The next day, Yun Yi woke up from his sleep and felt that the Xuantian Gong in his body was functioning as usual.

As usual, Yun Yi came to a place with a good view, and according to the familiar route of practicing Qi, with purple eyes, he practiced the Purple Demon Pupil as usual.

Yun Yi watched the rising sun, and saw a hint of purple in the distance. Yun Yi looked at the purple with surprise, and he clearly felt that the purple in his eyes was bigger than usual.

Yun Yi could roughly understand that as his cultivation level increased and his body transformed, the energy he needed would certainly increase. However, Yun Yi still didn't understand what the purple energy in his eyes was. That magical energy obviously had great benefits for his mental strength.

Yun Yi watched the purple in his eyes gradually disappear and fell into deep thought. Although the Purple Demon Pupil was an eye skill for him, it was more of a way to assist the growth of his mental strength. The flaw of the Purple Demon Pupil was also obvious. It could only be practiced at sunrise, and the progress of practice was very slow. If Yun Yi remembered correctly, according to Tang San, most of the Tang Sect disciples only practiced to the first level of the Purple Demon Pupil.

Mental power is an area that many people cannot explore and has great room for development. Yun Yi also knows in his heart that the Purple Demon Pupil is ultimately just an eye skill. However, this eye skill is of great help in the growth of mental power. However, if it is said that it can help soul masters cultivate mental power, it is far from reaching this level.

Yun Yi believed that a method of cultivation should at least be as good as meditation cultivation. It can be practiced anywhere and can significantly improve mental strength over a long period of time. The Purple Demon Pupil can only be regarded as an auxiliary effect in Yun Yi's understanding. During the more than ten years of cultivation, Yun Yi understood that the growth of mental strength was the result of the joint effect of multiple factors.

Meditation practice, physical growth and exercise, and the absorption of spirit rings can all help grow mental strength.

After thinking for a while, Yun Yi still had no specific direction. It was extremely difficult to create a method to cultivate mental power. This was also his shortcoming. Yun Yi's strong learning and comprehension ability was based on the premise that others pointed out the direction. Without direction, no matter how strong Yun Yi's ability was, he would not be able to display it.

"What are you thinking about?" A gentle voice sounded in Yun Yi's ears.

Yun Yi came back to his senses and saw Zhu Zhuqing approaching. He shook his head slightly and said, "Nothing, I'm just thinking about some problems in cultivation."

As Zhu Zhuqing got closer, Yun Yi also understood what the beauty in front of him meant. He smiled slightly, and then he hugged Zhu Zhuqing in his arms and gently kissed her cheek.

Zhu Zhuqing puffed up her lips slightly and said in a light voice, "You only know how to practice."

Yun Yi gently rubbed Zhu Zhuqing's head and chuckled, "A lot of things have happened during this period of time, and my little kitty has indeed been neglected."

Zhu Zhuqing turned her head slightly and blushed. She didn't say anything, but slowly leaned on Yun Yi's chest, found a comfortable place and rubbed it gently.

The two were being affectionate, when suddenly a silver bell-like chuckle came from behind, "Zhu Qing, you betrayed our alliance in just one day."

Yun Yi turned around and saw Ning Rongrong running towards him, jumping and skipping. Zhu Zhuqing blushed and gently pushed Yun Yi away.

Yun Yi chuckled upon seeing this and said, "Oh? Kitty, what agreement did you guys make behind my back?"

Zhu Zhuqing blushed and glared at Yun Yi. Ning Rongrong came over and took Zhu Zhuqing's arm, snorting and saying, "I won't tell you."

Yun Yi smiled and didn't care. He just raised his hand to help Ning Rongrong tidy up her hair which was slightly messy due to running.

Feeling the unintentional tenderness, Ning Rongrong's face flushed.

"Let's go, let's go eat." Yun Yi said with a smile.

Eating is a very enjoyable thing, especially eating with a beautiful woman. Of course, except for yesterday's binge eating to replenish energy, Yun Yi couldn't even taste many things.

Yun Yi also enthusiastically prepared a sumptuous breakfast for everyone.

After eating, Yun Yi said hello to everyone and headed towards the offering hall.

Seeing this, Ning Rongrong couldn't help but complain, "Sister Nana, why does Xiaoyi go there to practice every day? Isn't it better to practice here?"

Hu Liena smiled and said, "How can Xiaoyi have the energy to practice if he stays here? As for what Xiaoyi is practicing specifically, I don't know either. Anyway, it's not a good idea to stay here to practice."

Shui Bing'er and Zhu Zhuqing also nodded in agreement.

Yun Yi did not rush to the Offering Hall, but went to the Pope's Hall first. At this time, Bibi Dong was still sitting in front of the desk in the side hall. Perhaps it was too early, Bibi Dong did not deal with the affairs in the hall as usual.

"You come to my place so early, why don't you spend more time with them?" Bibi Dong looked at Yun Yi and joked.

"I'm here to ask you a question." Yun Yi said with a smile.

"Oh? Why don't you go up and ask those people?" Bibi Dong looked at Yun Yi and said meaningfully.

Yun Yi shook his head slightly and said, "What I want to ask today is related to spiritual power. You can guide Nana to develop into a pure spiritual soul master, so it is obvious that you have studied spiritual power."

Bibi Dong heard this, her eyes full of nostalgia, nodded and said with emotion, "Yes, that's right, I do have some research on mental power, what do you want to ask?"

Yun Yi whispered, "Do you think it is possible to create a method to cultivate spiritual power?"

Bibi Dong shook her head slightly and said, "Maybe, but it's not worth it."

Yun Yi looked puzzled and asked, "Why do you say that?"

"Xiao Yi, I understand what you are thinking. Due to the special nature of your martial soul, your body and cultivation are growing very fast. The faster you grow, the less room you have to explore. That's why you want to focus on your mental strength." Bibi Dong said slowly.

Yun Yi nodded in agreement when he heard this.

Bibi Dong paused and continued, "In fact, it's not just me who has thought about this question. Many people have thought about it, but many have given up."

"Why?" Yun Yi asked in confusion. "Many people cannot reach the level of Titled Douluo in their entire lives, let alone pursue a higher level of spiritual power? The mainstream use of spiritual power in Douluo Continent now is to sense and assist in combat, and a soul master who wants to experience the mystery of spiritual power must at least reach the level of Soul Saint."

"Even I made a great effort to let Nana take this path, because I know that Nana has a good talent, but her martial spirit is a bit average compared to the top martial spirits. If she follows the normal training method of agile attack spirit master, Nana can certainly achieve the title step by step, but she will be a bit mediocre among the titles, and may even be worse than a ghost. So I guess she took the path she is on now."

Yun Yi nodded slightly. After listening to Bibi Dong's words, he also understood that the main theme of Douluo Continent is still martial spirits. In order to compete for resources, soul masters mostly focus on combat effectiveness, and cultivation is the embodiment of combat effectiveness. The threshold of mental power is too high. Even if someone is willing to study it, they will soon be eliminated by the continent. Even though Yun Yi possesses extraordinary mental power, he can only use mental power to assist his battles.

A research with high threshold and low initial returns will eventually be abandoned in this world of endless fighting. This is why soul guides can develop so rapidly after ten thousand years in Douluo Continent.

The research threshold is low, the use threshold is low, and the benefits are huge both in the early and late stages. How can such a weapon not be attractive?

"Then tell me, should I still study methods to cultivate my spiritual power?" Yun Yi looked at Bibi Dong and said softly.

"You have a lot of time, of course you can try, but I think it's difficult, Xiaoyi, you have to understand that the martial soul and the soul master are actually a pair of twins. In a sense, the martial soul can be said to be another soul of the soul master. The soul master and the martial soul are mutually reinforcing. Soul masters will encounter bottlenecks in the process of soul power cultivation. Why do you need a soul ring to cultivate to level ten? In a sense, there is an imbalance between you and your martial soul, and at this time you need a soul ring to make up for it."

"The same is true for mental power. When a soul master and martial soul reach a certain level, the soul master can feel the existence of mental power. At this time, mental power will maintain a certain balance with martial soul and cultivation. The purpose of your creation of mental power cultivation method is that you want to make your mental power stronger, and at this time you will break this delicate balance."

Yun Yi's body shook when he heard this, and Huo Yuhao, one of the protagonists of the original novel, suddenly appeared in his mind. He suddenly understood why Huo Yuhao, even in the God Realm, was still the one with the strongest spiritual consciousness in the Douluo God Realm.

The key lies in the soul method created by Huo Yuhao and Alex. It not only allows soul masters to successfully obtain soul rings, but also retains the consciousness of soul beasts. From another perspective, isn't this consciousness mental power?
Yun Yi sighed secretly in his heart, and now he understood the key to creating a method to cultivate mental power. No, it cannot be said to be creating a method to cultivate mental power, because the prerequisite for greatly improving mental power is that mental power and martial soul must achieve a delicate balance. According to Bibi Dong, mental power cannot grow independently without martial soul.

Looking at Yun Yi's expression, Bibi Dong smiled and said, "It seems that you already have the answer in your heart."

Yun Yi nodded slightly and said, "There are thousands of ways to cultivate, but they all lead to the same destination. Even if I continue to improve my cultivation, my mental power and martial soul can also be improved under the influence of my cultivation, but they are supplemented by mental power. Even if I create a method to cultivate mental power, I will eventually encounter a bottleneck, and then I will need to improve my martial soul and cultivation."

Bibi Dong looked at Yun Yi and nodded with satisfaction, "It's good that you understand. Although you don't need to study the methods of spiritual power cultivation, I suggest that you study your body more. It is difficult for others to improve their martial souls. Only by relying on spirit rings can the martial souls change. But your martial soul is your own body. The biggest difference between your body as a martial soul and other martial souls is that you have more ways to grow, such as exercise, eating, and even autonomous development. If you truly understand everything about your body, you will become extremely powerful."

Yun Yi looked at Bibi Dong and fell into deep thought. He felt that he already knew his body very well, but Bibi Dong's words made him hesitate. Perhaps he did not understand it as well as he thought.

"Okay, it's time for me to take care of things. You can go upstairs and think slowly." Bibi Dong's voice brought Yun Yi back to his senses.

Yun Yi also bowed slightly towards Bibi Dong and said, "Yes, sister."

As Yun Yi was about to leave, he suddenly thought of Qian Renxue from yesterday and quickly reminded her, "That sister..."

Bibi Dong looked up and glanced at Yun Yi when she heard that. "What? Is there anything else?"

Yun Yi hesitated and said, "Sister Xue, she seems to know something."

Hearing this, Bibi Dong's face changed and she quickly asked, "What did she say to you?"

Yun Yi shook his head when he heard this, and then he recounted to Bibi Dong what happened yesterday.

"Sister Xue, when she came back, I felt that she had become different. It was as if she had let go of something and no longer looked as worried as before." Yun Yi said to Bibi Dong.

Bibi Dong looked a little unhappy when she heard this. Combined with what Yun Yi said, Qian Renxue did not come down to look for her yesterday, which made her very uneasy.

"Maybe Xiaoxue also thinks I am wrong." Bibi Dong thought to herself and couldn't help but smile sadly.

Seeing this, Yun Yi asked with concern, "Sister, are you okay?"

Bibi Dong took a deep breath and said, "Xiao Yi, after you finish your training today, can you bring her to my place?"

Yun Yi pretended to be ignorant of the truth and nodded to comfort him, "Of course, I believe Sister Xue will not blame you for the undercover matter."

Bibi Dong forced a smile upon hearing this and said, "Go ahead, I'm fine."

Yun Yi nodded slightly, then turned and left. Bibi Dong looked at Yun Yi's departing back. At this moment, she wished very much that those words of comfort had just been spoken by Qian Renxue.

Yun Yi sighed slightly after leaving the Pope's Palace, turned around and looked back at the magnificent hall. The weak are not qualified to make choices, and the same was true for Bibi Dong back then.

Yun Yi was thinking about going up the mountain. Soon, he saw Qian Renxue's figure outside the main hall of the worship hall.

Qian Renxue slowly walked forward and looked at Yun Yi and said calmly, "You're here too late. Are you ready to start?"

Yun Yi looked at Qian Renxue in front of him and asked doubtfully, "Start? Start what?"

Seeing Yun Yi's confused look, Qian Renxue raised her lips slightly and said, "Grandpa said that you have learned a lot and it's time to repay your debt. First, you will be my sparring partner until I beat you."

Hearing this, Yun Yi looked Qian Renxue up and down with strange eyes, as if he had heard the funniest joke in the world.

"Of course I can be your sparring partner. I'm just afraid that someone will need me to spar with him for the rest of his life." Yun Yi looked at Qian Renxue and chuckled.

Seeing Yun Yi's despicable look, Qian Renxue couldn't help but grit her teeth. A golden sword suddenly appeared in her hand, and she rushed towards Yun Yi in an instant, "Little... little thief, die!"
