Chapter 258: New Developments of Soul
When Su Yu took over Xu Jiawei's order, he knew that the Su family's affairs had been resolved satisfactorily, but he still would not tell anyone that his parents and clansmen were alive. Although these things might be used as bargaining chips by Jing Hongchen, Su Yu was not worried at all because Luo Yu was still in the Sun and Moon Empire.

This is his trump card, an unknown trump card for desperate situations!

After returning to the Su family, Su Yu did not hesitate at all and began to issue orders with Xu Jiawei's order.

In just three days, the Su family was in perfect order inside and out, and everything seemed to have returned to normal operation, but there was no longer the grand occasion of the past. The disappearance of Su Xinyuan made it impossible for the Su family to restore its former grand occasion.

Because his network of contacts was completely severed, although Su Yu could spend time to reconnect them, there was no need to do so.

"Boy, why do you want to go back to the world of the dead?" asked Old Yi kindly.

"I can't fall behind in my teacher's lessons. I still need to learn necromancy. After all, I am still far from getting the teacher's permission. Moreover, if I can't become familiar with the teacher's necromancy, how can I fully revive the teacher in the future?"

He had missed many classes on Yi Lao's necromancy, and now the situation had entered a brief period of calm, so he could calm down and concentrate on becoming a necromancer.

Under the guidance of Yi Lao, obscure and mysterious magic spells continued to be chanted from Su Yu's mouth, and he began to construct magic based on his mental power. There is no quick way to master necromancy. If there is, the price is that Yi Lao will pay with his own life.

In the original work, Huo Yuhao did not spend too much time learning Yi Lao's undead magic, but he was able to easily master the undead magic left by Yi Lao. This is obviously related to the third martial soul in Yi Lao's work.

Continuously overlapping magic arrays were rapidly constructed in the world of the undead, and complex magic runes were constantly taking shape and being engraved.

As time went by, the magic circle emitting black light suddenly shattered, and the gathered magic power also scattered at the moment of shattering.

"Cough cough cough..."

Su Yu coughed a few times in embarrassment. There was a price to pay for failing to cast high-level magic. Although the magic Su Yu cast now was not very high-level, the backlash was not that strong.

Relying on the body transformed by the gold of life, he can resist this backlash. At most, his blood and qi will surge a little, and it won't be a big deal.

"It seems that I need to practice more..."

Every failure is accumulating experience for success. If you always fall in the same place several times, it is very likely that you have made no progress.

"If it were a real battle, you would have already become a real undead. Your casting speed is too slow..."

The old voice echoed in Su Yu's ears, and Old Yi slowly condensed his body in front of Su Yu. Now Old Yi seemed to have recovered well, and even his previously illusory body had become a bit more solid. It was just unknown when he would be able to fully recover.

"Well, I'll practice more, practice more..."

Su Yu defended himself without any confidence.

Su Yu did waste a lot of time learning necromancy, but Yi Lao did not blame him. He had been watching Su Yu through his whole life.

However, Master Yi did not relax his assessment of Su Yu because of Su Yu's personal reasons. In the teaching of necromancy, Master Yi had very high requirements. The reason he gave was that as my disciple, the requirements were naturally higher.

Indeed, just a little.

Just a few billion...

"Don't even think about going out for the next two days. Practice the seven high-level magic circles I taught you today until I'm satisfied. If you continue like this, your great talent will really go to waste. What are you doing standing there? Go practice. I've already allocated a venue for you."

With a wave of Yi Lao's hand, Su Yu's feet were empty. Then, after a dizzying moment, he came to an open space in the world of the dead.

The place before me was a valley filled with corpses, and it was dead silent as far as the eye could see.

"I forgot to remind you that this Valley of Corpses may give birth to liches, abominations, skeletons, or... Anyway, you should pay more attention..."

"Hey, hey, teacher, you..."

Before he finished speaking, a pale skeleton arm grabbed Su Yu's ankle. The cold touch made Su Yu subconsciously want to circulate his soul power and summon his soul ring and martial soul. However, the next moment, he was dumbfounded. His martial soul was gone...

The soul ring is gone, and the soul power can no longer be sensed! !

…………

After a hectic fight with the enemy, Su Yu quickly adjusted himself. After all, he had been tortured by Yi Lao in the same way last time.

Although the seven high-level magic circles of the Yilao Sect were complicated, after practicing many times, he was able to barely maintain the circle until the end.

Of course, he also had to be on guard from time to time against those guys suddenly punching Su Yu!

Looking at the huge army of undead outside the Corpse Valley, Su's heart was so excited that he couldn't even express it in words. Given time, who wouldn't be an undead summoner?
three days later.

Exhausted, Su Yu slumped down on a stone. Three days of high-intensity magic output made Su Yu feel that his mental strength had been completely drained.

"In the past three days, I did a simple experiment, and it turned out that my guess was correct." Old Yi came over with a manuscript that Su Yu couldn't understand.

The writing on the manuscript was neat, but Su Yu could not understand a single word. This writing was different from the writing on Douluo Continent and Blue Star. It was obviously some kind of writing from the world that Yi Lao once lived in.

"Although I can't study the nature of martial spirits for the time being, I can solve the problem of spirit rings by transforming the spirit beast's soul into a spirit through a contract. This proves one thing: the essence of spirit rings is a special energy derived from the spirit beast's soul."

"Before that, Huo Yuhao was able to gain a blank ice-type martial soul from an ordinary spiritual-type martial soul due to the sacrifice of the giant bug. This shows that the martial souls of humans on Douluo Continent can be supplemented through some channels."

"However, these are just my speculations. I have limited energy now and cannot complete so much research, so I have done some analysis based on the spirit rings you absorbed in your previous soul contract. Facts have proved that the spirit rings absorbed by spirit masters come from a certain power in the soul of the spirit beast, and the process of you absorbing the spirit rings is to eliminate the consciousness and part of the soul belonging to the spirit beast."

"In terms of the creation of soul spirits, we don't necessarily need the soul of a soul beast. We can collect power from the soul beast and use part of the soul of the soul beast as a medium. Maybe we can make a prototype of a soul ring, but I still need a soul ring as research material. I think the little black dragon named Di Tian will be very interested in this matter."

Although Old Yi is in the state of a remnant soul, with the passage of time, his memory is gradually recovering. If Old Yi really recovers to his heyday, he will probably be able to defeat those guys living in the sky.

"But, teacher, I have a question?" Su Yu knew what Alex was planning. Why did the soul ring of a soul beast have to be produced after death? It was most likely related to the realm of the soul, and Master Yi was a top expert in this area.

"Little guy, what do you want to say?" Alex looked at Su Yu puzzledly.

"If we use the soul of a soul beast as a medium, how do we collect the power of the soul beast? Should we extract it directly from the soul beast's body, or use necromancy to absorb it? Moreover, no matter what experiment we do, we need experimental subjects. But where can we find the experimental subjects for the first stage?" Su Yu wiped the cold sweat from his forehead. Old Yi was really brave.

"This brings me to the experiment I did these past two days." Yi Lao chuckled, looked at Su Yu and continued, "Although you were the only one who used our Soul Contract before, and the result was not perfect. However, after that, I made some new improvements, and also did some experience summary and material collection based on the changes of those two little guys."

"During these three days, I tried to extract some souls from those two guys. As souls, their own powers also carry some unique characteristics from their lifetime, so before we officially conduct the soul ring experiment, we used them as materials. As for you, you are naturally the container."

Su Yu's face changed, "Isn't it possible that I am the guinea pig in that experiment?"

"What kind of experimental guinea pig are you? As the only human being who has successfully completed the soul experiment, you are naturally worth studying. Don't worry, you won't die if you fail. The worst that can happen is that both our master and disciple will become undead creatures. But don't worry, the experiment will be conducted in the undead world, not in your sea of ​​consciousness."

"So when should we set out? I think it's best to discuss this with Di Tian. We really don't have enough materials. If we continue to try like this, we will have to do some research on life forms in the end. Many soul beasts die in the Xingdou Great Forest every day, and with the teacher's current condition, we should be able to do research for a long time."

Let's get back to the topic. Although Su Yu is a good example, research on substitutes for spirit rings also requires experiments on living organisms.

There has been no substantial progress in the soul experiment. Although Di Tian knows that they have no way to rush such a major event, Su Yu also hopes that there will be some progress.

Otherwise, if the big promises you made are dashed, you will lose all your credibility.

In fact, Su Yu and Yi Lao had always discussed the research on souls. The research on souls in later generations was done by killing a large number of soul beasts and conducting countless experiments to fill the gaps in theory with practice.

Facts have proved that the soul experiments of later generations involve the soul aspect. In a sense, the Soul Ascension Platform is the gathering place of soul beasts’ souls and soul rings.
