Lei Jingshen looked at Xue Wei. He did not mind the fact that he was so honest. Although it sounded like he wanted to turn Lei Jingshen into a guinea pig, this was the kind of risk that one needed to take if they wanted to get more strength.
Strength was not something that came naturally. One had to fight for it or build it up slowly. If there was a chance of suddenly building up one's strength rapidly, one had to be careful.
There was a chance that it would destroy one's foundation, making it unstable, and if this were not the case, then it would bring with it tremendous risks.
Was he, Lei Jingshen, someone who cowered in the face of danger? He understood that what was being done would place him in danger, but he was willing to take the risk as it might push him even further.
Xue Wei nodded his head in approval. He had not assumed wrongly; Lei Jingshen was a true warrior with a heart that beat for cultivation. Although he might lose his life, he was willing to take the risk.
"Let's find a peaceful place. Lin Xuan, you will have to stand guard."
Lin Xuan was not at all insulted by Xue Wei ordering him to become a mere guard, and he nodded his head with a grim expression.
Xue Wei and Lei Jingshen entered a big tent. This tent was reserved for the Emperor and King ranked experts, and one could only enter if they got permission.
This tent had formations and inscriptions imbued around it, so only those who had a strength that could rival Lei Jingshen's could actually enter. It was the last defense of the army's current base.
It was the most suitable place to try and see what would happen when Lei Jingshen got infused with essence blood from the Holy Son of the sovereign beasts.
While Xue Wei was inside, Lin Xuan gave free rains to another King ranked expert to find nine soldiers with good talent or high tolerance for pain, so that they could be mutated as well.
These Kings and Emperors had heard much about Xue Wei before, and knowing that they would be seeing him do his magic upfront, they became excited.
This King ranked expert was not jealous of Lei Jingshen. While he also wished he could get such a boost in strength, he was a human, and thus unable to undergo the mutation.
As soon as Xue Wei entered the tent, they found the bed belonging to Lei Jingshen. Here the Blue-Eyed Lightning Leopard sat down in a meditational trance and cut a slash on his arm. When the blood began flowing, Xue Wei also cut a wound on his finger. The wound was small, but every drop that left his body was essence blood. He dropped five drops into the wound on Lei Jingshen's arm, and after finishing the wound closed by itself again.
Lei Jingshen was about to say something when a soul-wrenching pain erupted inside his body, making his face pale and his body tremble.
He instantly understood why some of the previous people had not survived this torture. While the normal blood was supposed to be much lighter than the essence blood, Lei Jingshen was a King ranked expert, so he should also be able to withstand more pain.
Gritting his teeth, Lei Jingshen had no other option than to wait for the pain to subside. He could not control it at all, his body was being wrecked with pain, but he also felt a strange new energy roaming in his meridians. He felt how his Qi was being purified, and he felt his innate talent rising compared to before.
The more pain he felt, the more his body was improving, and this alone was enough for him to hold on for dear life. He was like a small boat on the stormy sea. He had no other option than to try his best to survive, since if he could not hold on, only death awaited him.
He was able to avoid screaming in pain, but that was not because he did not want to, but because his body was paralyzed due to the transformation. He could only clench his teeth as he allowed the pain to run rampant in his body.
After two days, there was no change to Lei Jingshen's situation, but Xue Wei was relieved. Since he could withstand it for so long, he was more or less out of danger.
As such, he began fetching the regular experts who would receive a normal mutation, giving them blood one after another. After he was done, his face was slightly pale, but he did not mind. Instead, he took out a few healing pills, threw them in his mouth, sat down on the ground next to the many mutating experts, and began cultivating. He had to restore the amount of blood he had used.
After a week, Lei Jingshen woke up from his coma. He looked like a ghost, his face was pale as if there was no blood at all beneath the skin. His movement also seemed somewhat rusty, as if he still experienced pain with each move, but a brilliant smile hung on his lips.
He often went to find Lin Xuan, the two of them seemed to understand the other's thoughts, and they discussed the mutations in detail to understand the changes that were happening when using essence blood versus normal blood.
They planned on telling Xue Wei their results later so that he could use it to mutate his friend. However, it was clear that the subject of the essence blood mutation had to be a King ranked expert or above.
