Due to the high cost of materials, Li Changsheng did not slack off in the production of high-grade dissolving agents, especially robots, who meticulously integrated various materials.

Soon, Li Changsheng's forehead was covered with sweat.

"Kaylan!" Li Changsheng called, once the sweat drops in the high-grade dissolving agent, the consequences are very serious.

Kailan flew over, holding a silk scarf in her hand and gently wiping sweat for him.

After wiping, Kailan immediately flew to the corner as light as silent, for fear of disturbing Li Changsheng, who was extremely focused.

"Add candlelower powder!" At this time, Li Changsheng added the last candlelower powder and then covered the lid.

The small fire simmered for a quarter of an hour before Li Changsheng put out the flame. After opening the lid, he saw a small pool of purple liquid in the container.

This is the advanced dissolving agent. Li Changsheng can't wait to install them in test tubes. There are three tubes in total. Finally, the test tubes are completely sealed.

"Done!" Until now, Li Changsheng was relieved.

At this time, Kailan condensed a small group of water of life. Li Changsheng opened his mouth and swallowed the water of life.

The water of life had an immediate effect. Li Changsheng felt warm all over, as if he were in the warm sun in winter. His limbs were full of strength, and his spirit was restored to its peak.

"Hard work, Kelan!" Li Changsheng stretched out two fingers and touched Kailan's small head.

"No hard work!" Kailan smiles happily, her smile is still clean and spotless, not infected by the dye vat of the world.

At the next moment, Li Changsheng began to set up the restraint system. He decided to purify the blood of white tiger immediately.

Soon, the restraint was completed and began to be activated.

Li Changsheng stands in front of the experimental platform and takes out the semi-finished blood from the space ring. As long as the advanced blood vessels in these blood are removed, the pure white tiger essence blood can be purified.

After taking the medicine, Li Changsheng's visual field changed immediately, and two kinds of blood vessels could be seen.

Among them, the white tiger blood vessel imprint accounts for the majority, while the advanced blood vessel imprint belongs to the inactive recessive blood vessel, which is far less than the white tiger blood vessel in quantity.

Li Changsheng took out a high-level dissolving agent and fell down to the blood in the vessel and started the final purification experiment.

He has done many purification experiments. According to his calculation, even if the power of purification is not up to 10%, 8% still exists, and there is no probability of failure.

Although there is a big gap with the complete blood vessel book, it is much higher than the purification efficiency mastered by Yuanling Academy. In addition, the purification technology of Xuefu still has a great probability of failure.

This is the main reason why Yuanling academy never wanted to purify the blood essence of sanzujinwu. With the purification efficiency and success rate of nakengda, even if all the goblins with three feet of Jinwu blood in Langya state were purified, not enough blood essence could be purified.

The high-grade dissolving agent works quickly and slowly wraps up most of the high-level blood vessel marks.

Soon, the structures of these high-level bloodstains began to collapse, dissolve, and eventually precipitate into the bottom of the vessel.

Soon, Li Changsheng was very painful and poured half a root of high-level dissolving agent, which completely stripped the high-level blood contained in the blood.

The whole process lasted half an hour. At this time, the bottom of the vessel was filled with a large amount of sediment. When the last trace of high-level blood disappeared, the blood suddenly burst into a strong golden light. These lights quickly gathered and finally turned into a clear white tiger shadow.

Just the shadow, it brought a very strong pressure to Li Changsheng. He quickly opened his five star orifices and was covered with a layer of bright stars.

From the point of view of the feeling, the prestige of the white tiger shadow has been comparable to the dragon power of the adult black dragon, giving people a feeling of not angry but powerful.

Under this strong pressure, the restraint system began to feel like a collapse. Fortunately, before the collapse, the shadow of the white tiger had turned into a golden light and penetrated into the blood again.

This vision was not detected by outsiders. Soon, after filtering out the magazine, Li Changsheng poured the golden white tiger blood essence into the bowl, just got a large bowl of white tiger blood essence.

After finishing the treatment, Li Changsheng can't wait to come to the backyard and summon AI Xi out.

It seemed that she had a resonance with her own blood, and her eyes were full of greedy humanity.

"Ash, this is the white tiger blood essence I specially prepared for you!"

With great temptation, AI Xi reluctantly moves her sight away from the white tiger blood essence and turns to Li Changsheng.

"You are my life demon pet, I will not treat you badly, drink it, I believe you will become stronger!" Li Changsheng held the bowl and put it in front of AI Xi. His heart was full of expectation.

At this time, AI Xi has reached the upper level of 9, as long as you drink this bowl of white tiger blood essence, I believe it will follow the trend to complete the breakthrough in the world.Of course, this is not the most important. If AI Xi's white tiger blood is further improved, its race will also be greatly improved, and its strength will certainly increase greatly.

Roar ~

AI Xi gave a joyful roar, gently arched Li Changsheng with his huge tiger head, opened his mouth, and a strong suction force was generated, just like a long whale sucking water. The white tiger blood in the bowl flew up and fell into the mouth of ash accurately.

As soon as she lifted her neck, she swallowed all the blood essence of the white tiger.

In the blink of an eye, the white tiger blood essence began to play a role, and it fused with the blood of ashy. Ashy quickly fell on the ground, and felt that the blood in her body seemed to be boiling. There was no pain in her body, and it was even more itchy.

It's hard to express this feeling in words. All in all, the pain ashie suffered this time was more intense than the last time she took the blood fruit.

At this time, AI Xi's whole body was full of gold and green light, and its body began to increase at the speed visible to the naked eye, from six meters to eight meters, and finally the change slowed down.

At the same time, in the sea of consciousness of AI Xi, a clear shadow of a white tiger appeared, which was quickly swallowed up by AI Xi. In this blood transformation, it once again obtained part of the inheritance from the white tiger.

The whole process lasted for about half an hour, and the glory wrapped in ashy slowly shrank, revealing her growing tiger body.

AI Xihu's body shook, sending out far more than before the prestige, although there is still a gap with the white tiger shadow before, but the difference is not very far.

With the help of this bowl of white tiger blood essence, AI Xi's blood rose successfully, which directly led to the completion of its evolution and a breakthrough in the realm.
