The body of Half-Step Great Power Yang Xing was put into the machine room. Li Shiming took out some blood with strange energy and mixed it with other fourth-grade top-level corpse refining materials.

This blood is also extremely crucial. It is collected from the body of Yang Xing, a half-step great man.

The blood cannot be used directly after it is taken out, it needs to be transformed. Based on IBMz15's analysis of the blood of multiple corpses, IBMz15 estimated the composition of the blood of 'Flying Yaksha'.

Li Shiming spent decades in the computer room, constantly transforming the blood with a precision of 0.05 nanometers, resulting in the blood that is infinitely close to the blood of 'Flying Yaksha'.

During the corpse refining process, if you want to refine a corpse of a certain level, you must use the blood of the corresponding corpse as a medium.

He didn't have the blood of 'Flying Yaksha', so he could only research and transform it by himself.

Of course, even if the 'Flying Yaksha' existed, with his strength he would not be able to obtain blood from the 'Flying Yaksha'.

He even suspected that there was a 'Flying Yaksha' standing there, and he couldn't tear open the 'Flying Yaksha's' skin defense.

The blood that he created that looked like the 'Flying Yaksha' was mixed with a variety of top-grade fourth-grade corpse refining materials to form a special talisman ink.

Finally, he added his essence and blood, as well as a part of his spiritual energy into the talisman ink.

This is a method developed by IBMz15 to enhance the recognition of the master by the corpse. After adding spiritual energy, it is equivalent to adding the soul of the master to the process of forming the corpse's soul. This makes the corpse easier to control and reduces the risk of backlash.

Of course, this research has little practical use for other cultivators, because no cultivator would consume his or her own spiritual energy in order to refine a corpse. This is the energy of his or her own soul.

Under normal circumstances, the failure rate of refining a corpse, especially refining a high-level corpse, is very high. If the cultivator consumes his mental energy every time he refines a corpse, he will go crazy due to the loss of his soul without even having to wait for the corpse to be refined.

Li Shiming is different. He has 191 brains, each with its own spiritual energy. He does not worry about excessive consumption of spiritual energy that would affect his own soul.

He began to draw runes on the body of Yang Xing, the half-step great man. With his current level of ability and more than a hundred brains operating at the same time, this task was not difficult.

During the period of drawing the runes, the prepared corpse refining formation can generate more Yin and cold energy. This time it is not about refining a golden corpse, so the more Yin and cold energy needed, the better.

The corpse of Yang Xing, a half-step great power, is of very high quality and can naturally carry more "corpse refining runes".

Before, he used the corpse of a great monk at the peak of his powers, but he only drew 400 million "corpse refining runes" before the corpse reached its limit.

As for the corpse of Half-step Great Power Yang Xing, he drew a full 2.5 billion 'Corpse Refining Runes' before the corpse of Half-step Great Power Yang Xing reached saturation state.

Two and a half billion "corpse refining runes" are densely covered inside and outside the body of Yang Xing, a half-step great man. All the "corpse refining runes" maintain a balance of energy.

This is thanks to the precise calculations of IBM z15. Otherwise, once an energy imbalance occurs, the probability of failure in the refining process will increase greatly.

He placed the corpse of Yang Xing, a half-step great man, into the corpse refining array. At this time, the corpse refining array had absorbed energy for ninety-nine days, and the cold energy inside was about to condense into cold spiritual mist.

Just over ten breaths after the body of Half-step Great Power Yang Xing was placed into the Corpse Refining Array, the cold and gloomy energy in the Corpse Refining Array seemed to have found an outlet and flowed into the body of Half-step Great Power Yang Xing.

A large amount of fourth-grade top-level corpse refining materials in the corpse refining formation were all flowing into the corpse of Yang Xing, the half-step great man, with different corpse refining energies.

Li Shiming stood outside the corpse refining formation, watching the corpse refining process quietly.

He needed to record every change in this corpse refining to provide reference data for subsequent improvements.

He did not think that he could succeed in one go. After all, he was refining the 'Flying Yaksha', a refining method that had never been heard of in the world of immortal cultivation.

On the body of the half-step great power Yang Xing, countless "corpse refining runes" lit up, and the corpse became a luminous body.

He activated the 'Divine Eyes' and at the same time controlled the corpse refining formation to sense the changes in the corpse of Yang Xing, a half-step great power, within the formation.

The body of Yang Xing, the half-step great man, is transforming into a refined corpse. This is not beyond his expectations, and the whole process is still under his control.

The 2.5 billion "corpse refining runes" began to refine the corpse of Yang Xing, a half-step great man, in the corpse refining formation, and the first unexpected thing happened to him.

Originally, he had expected that the 'corpse refining rune' would be transformed into 'speed rule mark', 'strength rule mark' and 'defense rule mark', just like the previous golden corpse refining.

But on the body of the half-step great power Yang Xing, a fourth rule mark appeared, that is, the 'thunder and lightning rule mark'.

The 'speed rule mark' was due to the fact that he had added the core of the golden corpse from Tianren Dongtian into the ink talisman. The 'strength rule mark' and the 'defense rule mark' were converted autonomously by the corpse during the corpse refining process.

Strength and defense are two abilities of corpse refining, and also two basic abilities.

However, Li Shiming did not expect that the "lightning rule mark" that appeared on the body of the Half-step Great Power Yang Xing was because the Half-step Great Power Yang Xing himself was a Half-step Great Power of the Thunder Element?

Li Shiming was not aware that, at this point, the corpse refining process was deviating from the IBMz15 simulation process and was heading towards an unknown direction.

"Crack". Continuous sounds were heard from the body of Yang Xing, the Half-Step Great Power. These were the sounds of his bones being transformed.

The corpse of Yang Xing, a half-step great man, was lifted up into the air by the corpse refining formation. Instead of growing bigger, his body shrank instead.

The half-step great power Yang Xing was very tall, nearly 1.9 meters tall, but at this moment he had shrunk to 1.2 meters.

Behind him, a pair of bony wings appeared, and then a layer of membrane formed on the surface of the bony wings.

Li Shiming can't do anything now. He can only record all the data and analyze and study them slowly later.

The face of Yang Xing, who was half a step away from becoming a powerful being, was also changing, slowly transforming into a face with a sharp mouth and fangs, and no longer had any resemblance to Yang Xing.

"Huh!" Li Shiming discovered at this time that a fifth rule mark appeared on the body of this corpse with sharp mouth and fangs.

The fifth type of rule mark only appears on the wings of the sharp-mouthed and fanged corpse, and a "space rule mark" appears on each of the two wings.

Li Shiming could no longer understand the sharp-mouthed and fanged corpse in front of him. Everything was out of control.

What follows is the most crucial scene. The soul fire begins to grow in the body of Sharp-Billed Fanged Man, and his heart begins to beat slowly and powerfully.

The soul fire was very small at first. As soon as it appeared, Li Shiming sensed the existence of the contract, which made him feel much more at ease.

Although many of the situations that occurred were beyond expectations, this enhanced master-client contract did not fail.

The soul fire became stronger and stronger. After a hundred breaths, the strength of the soul fire exceeded that of a fourth-grade late golden corpse, and it was still growing.

Its heart began to beat normally, once every ten breaths, circulating the body's energy each time.

Suddenly, the corpse with pointed mouth and fangs let out a sharp howl towards the sky. Its aura suddenly rose, breaking through the late fourth level and reaching a new realm.

At this time, Li Shiming felt the repulsive force coming from heaven and earth.

He felt it from the Sharp-Mouthed and Fanged Corpse through the contractual relationship between them.

He knew that this was an impending thunder tribulation. Regardless of whether the Sharp-Billed and Fanged Corpse could survive the thunder tribulation, it at least showed that his process of refining the 'Flying Yaksha' was relatively successful.

However, he looked at the sharp-mouthed and fanged corpse in front of him and wondered if it was the 'Flying Yaksha'.

The corpse with pointed beak and fangs is different from the 'Flying Yaksha' in the records. It has an extra pair of wings and the ability to control space.

What Li Shiming didn't know was that the half-step powerful blood transformation that he and IBMz15 were researching contained too much imagination. Although IBMz15 referred to a large number of classics, these classics did not have any detailed data and were completely specious descriptions.

Therefore, the so-called 'Flying Yaksha' blood that he transformed has nothing to do with the real 'Flying Yaksha'.

But the blood he modified has theoretical support and possesses the characteristics of fifth-grade corpse-refining blood. Even though many of these characteristics are speculative, the fifth-grade characteristics do exist.

The consequence of using this blood as a medium is that unknown changes occur.

The appearance of a corpse with pointed mouth and fangs is not surprising. In fact, being able to refine a corpse is considered a success. It is possible to refine any monster using that imaginary blood.

Li Shiming was just about to add the secret method of lightning resistance to the Sharp-Billed and Fanged Corpse Refined, which was also the reason why he dared to refine a high-level corpse.

Although the thunder-resistance secret technique blessed by the 'Shenxiao Thunder Pearl' cannot reach the level of a great power, it is far superior to the effect of the thunder-resistance secret technique performed by the peak thunder cultivators.

It is because of the existence of the secret method of thunder resistance that he can maintain a very high success rate when refining corpses.

But before he could give the Sharp-Mouthed and Fanged Corpse the secret thunder-resistance technique, the Sharp-Mouthed and Fanged Corpse suddenly appeared in the sky and stood under the thundercloud.

Li Shiming frowned slightly. Although he did not order the Sharp-Billed and Fanged Corpse Refiner to accept his secret method of resisting thunder, the Sharp-Billed and Fanged Corpse Refiner took the initiative to rush towards the thundercloud without receiving his instructions. It seems that there are still some hidden dangers in cross-level corpse refining.

The corpse with sharp mouth and fangs howled at the thunderclouds, which was a provocative act.

In any case, Li Shiming would not do this, as it would cause the thunder calamity of heaven and earth to intensify.

Sure enough, amid the howling of the sharp-mouthed and fanged corpse, the thunderclouds in the sky more than doubled in size, and lightning flashed in the thunderclouds.

Li Shiming felt the thunderclouds in the sky and his scalp tingled. This was the strongest thunder tribulation he had ever encountered.

While he was thinking about it, the first bolt of lightning struck.

The corpse with sharp mouth and fangs did not dodge and allowed the thunder to strike him.

The corpse with pointed mouth and fangs let out a scream, and cracks appeared on his skin.

It is visible to the naked eye that these cracks heal quickly once they appear, and the speed at which the cracks appear and heal is almost the same.

"What a strong recovery ability!" Li Shiming couldn't help but exclaim.

The Sharp-Mouthed and Fanged Corpse's ability to recover is such that it can most likely fight a long war of attrition with the enemy as long as it is not killed instantly by one strike.

"Boom", the second thunder fell and hit the body of the corpse with sharp mouth and fangs.

This time, not only were there cracks on the skin, but the muscles beneath the skin were also torn.

But at the same time, the skin and muscles began to heal quickly.

When the third bolt of lightning struck, the wounds on the sharp-mouthed and fanged corpse's body were so deep that bones could be seen.

Li Shiming was about to be happy when he saw the sharp-mouthed and fanged corpse taking on three thunderbolts, but he discovered that the thunderclouds in the sky did not disappear, but were growing thicker and thicker.

Only then did he realize that this was not an ordinary golden corpse tribulation, but a stronger tribulation.

The fourth bolt of heavenly thunder struck, shattering a large area of ​​the skin and flesh on the body of the sharp-mouthed and fanged corpse, and then quickly grew out again.

There was a period of twenty breaths between each round of heavenly thunder. No matter how badly the Sharp-Mouthed and Fanged Corpse Refiner was injured by the previous round of heavenly thunder, twenty breaths was enough for it to recover to its best condition.

When the eighth heavenly thunder came, the corpse with sharp mouth and fangs looked extremely miserable. Except for its head and wings which were still intact, the rest of its body was destroyed by the heavenly thunder.

After the eighth heavenly thunder ended, the body of the sharp-mouthed and fanged corpse began to recover again.

However, the injury this time contained the destructive power of the rules of heaven and earth, and the recovery process of the Sharp-Mouthed and Fanged Corpse was obviously slowed down a lot.

Li Shiming was extremely nervous. It had come to this point, and if he could hold on a little longer he would be able to survive the catastrophe.

But he couldn't help Sharp-Billed and Fanged Man to refine the corpse. If he intervened at this time, he had a feeling that he would also be listed as a target of disaster by the rules of heaven and earth.

With his defense, any bolt of lightning could destroy his soul.

This made him dare not interfere with the tribulation process of the Sharp-Mouthed and Fanged Corpse Refiner. If he had used the secret thunder-resistance technique before the tribulation, there would have been no problem, but now he was already in the process of tribulation.

Now it all depends on the ability of the Sharp-Billed and Fanged Corpse Refiner, but he is not optimistic about the Sharp-Billed and Fanged Corpse Refiner.

Because the Sharp-Mouthed and Fanged Corpse, which had survived the eighth heavenly thunder, had obviously reached its limit, it would be too difficult for it to survive the strongest ninth heavenly thunder.

Suddenly, Li Shiming's figure flashed and he retreated several thousand meters away.

The thunder condensed from the thunderclouds in the sky gave him a great sense of threat before it was even fired. Although his location was outside the range of the heavenly calamity, his sense of danger told him that if he stayed where he was, he would most likely be affected.

Finally, the ninth thunderbolt fell. It was a dark golden thunderbolt, carrying with it the power to wipe out everything.

Li Shiming felt like the end of the world had come, and the world lost its color at this moment.

The wings of the sharp-beaked and fanged corpse retracted, wrapping its injured and unhealed body in the wings.
