Seeing Zhang Ying with a confused face, Ye Feng suddenly reacted, slapped his forehead and said, "Forget, you can't accurately feel the intensity of life." ”

Although the supernatural beings, within a certain range, can feel each other's life intensity, but this feeling is only an approximation, and it is not accurate to how many numbers, unless it reaches the three-star evolutionary, the life intensity can be felt in detail.

Ye Feng was able to accurately feel the strength of his life, entirely because he was a spiritual power evolutionary, and in terms of perception ability, he far surpassed other evolutionaries, and in addition, Ye Feng, who had experienced the end of the twenty years, was already very familiar with the life intensity, so he could naturally feel any nuances.

The health intensity has increased from 1.24 to 1.29, such an increase, on the whole, is actually not much, and it is obviously unrealistic for Zhang Ying to feel how much it has increased very accurately.

It's like a person with a height of 176CM, who sleeps and gets up and suddenly grows 1CM taller, obviously can't feel taller.

I can't feel it, it doesn't mean that the growth rate is slow, I grow 1CM tall in a day, it is 30CM in a month, and I am afraid that it will be a giant in a few months.

"I can feel it!" Zhang Ying raised his head and looked at Ye Feng.

At this distance, Zhang Ying could also feel Ye Feng's life intensity, but obviously she didn't understand what Ye Feng meant, Ye Feng was able to reflect the life intensity with accurate numbers, while Zhang Ying could only roughly feel that Ye Feng's life intensity was stronger than her.

"I've gained a lot today, let's extract the evolution liquid together!" Ye Feng didn't intend to dwell on this issue, after all, the life intensity had not yet formed a complete research system, and it was more troublesome to explain to Zhang Ying, knowing that it would not bring substantial benefits in the future.

Ye Feng said as he walked to the front of the test bench, ready to ask Zhang Ying to help, otherwise he would not have to sleep at night if he wanted to completely extract more than six hundred crystal nuclei into evolution liquid.

Zhang Ying also walked to the side of the test bench, ready to give Ye Feng a hand on the side.

The two of them cooperated very tacitly, and the speed of extraction was also very fast, but Rao was like this, by the time all the crystal nuclei were extracted into the evolution liquid, it was already four o'clock in the morning, and from seven o'clock in the evening to four o'clock in the morning, it took almost nine hours.

By the time they were done, Ye Feng and Zhang Ying were already sweating profusely, don't look at the extraction of the evolution liquid just fiddling with the equipment, this is a highly focused job, which is not at all easier than physical work.

"Yes, a total of fifteen evolution liquids have been extracted." Looking at the test tube rack full of fifteen evolution liquids, even though Ye Feng, who was tired all over, also showed an excited expression, and at the same time, he was also glad for the initial choice, Zhang Ying's ability was really domineering.

Today, more than 600 crystal nuclei were obtained, of which more than 400 crystal nuclei were obtained by Zhang Ying.

Zhang Ying kills zombies very quickly, and is almost not afraid of being injured, for other abilities, even if it is more powerful than Zhang Ying, it is far inferior to Zhang Ying, after all, Zhang Ying is not afraid of being injured, and her strong regeneration ability can allow her to fight in any crazy way.

"Take it, after the injection, sleep well, and continue the hunt tomorrow." Ye Feng took out two bottles of evolution liquid, handed them to Zhang Ying and said.

For one-star evolutionaries, a maximum of two evolutionary fluids can be injected at a time is the limit, if there are too many, the body cannot absorb them, which is equivalent to waste.

Zhang Ying took the evolution fluid, his eyes were full of a hint of longing, after Zhang Ying was reborn, his mood changed a lot, and he was even more eager for power.

"Before you get injected, remember to eat some chocolate or powdered milk." Seeing Zhang Ying take the evolution liquid, Ye Feng instructed again.

Evolution fluid can transform the body, and can also be used as energy to supplement the energy consumed by the body.

This is somewhat similar to the process of eating milk in the human body, if a person drinks milk hungry on an empty stomach, the nutritional value becomes very low, because the protein in the milk is broken down as energy and cannot be absorbed and utilized.

Therefore, generally before drinking milk, eating a steamed bun can greatly improve the milk utilization efficiency, because the starch in the steamed bread can be converted into sugar, and with the steamed bread providing sugar as energy, it will not decompose the protein in the milk.

The same is true for the use of evolutionary fluid.

After telling Zhang Ying, Ye Feng walked to his temporary bedroom, and before lying down, Ye Feng took out a few bags of Snickers from the space ring, tore open the bag, put it in his mouth and chewed it.

Half an hour after eating Snickers, Ye Feng began to inject the evolution solution, and after injecting two evolution solutions in a row, Ye Feng lay down on the bed with a satisfied face.

Now that there is enough evolution liquid, Ye Feng doesn't have to worry about his evolution being slowed down, as long as the evolution liquid is sufficient, Ye Feng is confident that within half a month, his life strength will be close to 3 times that of ordinary people, that is, the strength of a one-star peak.

As soon as the day dawned, Ye Feng, who had only slept for a few hours, got up from the bed, as long as humans ensure five hours of sleep a day, they can maintain basic physical rest, as an evolutionary, they can compress this time even shorter.

Ye Feng got up and left the bedroom, and when he came to the hall, he saw Zhang Ying, who was slightly stunned, only to see that Zhang Ying had changed out of the sportswear he had worn last night, and put on a set of dark robes that covered his whole body, and was engrossed in practicing chopping with an axe.

Zhang Ying also found Ye Feng who got up, but his movements were slightly sluggish, and then he continued to practice.

Ye Feng came to the test bench, continued to sort out some experimental equipment, and put all these instruments for extracting evolution liquid into the space ring, and then searched for it in the laboratory, and put all the items that might be able to be used in the future into the space ring.

Now Ye Feng's space ring has ten cubic meters of reserve space, which can hold a lot of things.

"Shadow, let's go!" After Ye Feng collected the things he needed, he walked past the shadow and said lightly.

Zhang Ying didn't speak, stopped chopping practice, put the short-handled axe into the wide cuffs, and silently followed behind Ye Feng, just like Ye Feng's shadow.

Ye Feng left the laboratory and walked towards the school parking lot, now Zhang Ying has recovered, although the degree of evolution is not high, and the life intensity is only 1.29, but because of the domineering ability and strong combat effectiveness, it is not weaker than those evolutionaries who have reached 1.8 or even 2.0.

Now Ye Feng, after two nights of the assistance of the evolution liquid, his life intensity has also increased from 1.86 to 1.90, and with a superb fighting technique, he is already very strong.

The most important two people's abilities can be completely complementary, Zhang Ying has the ability to regenerate, and can be used as a meat shield to block the front, while Ye Feng is a spiritual power evolutionary, with the ability to attack accurately, as well as judgment beyond ordinary people, as soon as he makes a move, he attacks the opponent's vital points.

Under the two joining forces, the combat power is superimposed, not simply one plus one equals two, but greater than three.
