After Ye Feng extracted and completed the phagocytosis gene, he used the anesthetics and experimental equipment in the laboratory to simply make several anesthetic bombs, which were invented by human beings after the end of the world and used by humans themselves.

After all this, he decided to leave Nongda, although the zombies of Nongda were crushed by Ye Feng, and after this period of hunting, there were thousands of fewer women.

And most of the zombies were led by Ye Feng to the east gate of the school, and the experimental building where Ye Feng was located was close to the west gate, which was relatively safe, but Agricultural University belonged to one of the urban centers of Yashi, and the zombies here were very dense, and it was not suitable for long-term waiting.

There are a large number of zombies, and the possibility of naturally evolving high-level zombies is great, once a third-order zombie is evolved, even if Ye Feng is right, it is difficult to escape, and the third-order zombie can completely crush a one-star ability.

With the improvement of the level, in addition to the strength will double, the IQ will also slowly increase, the second-order zombies are compared to the first-order zombies, and they already know that picking up the weapon to attack humans can improve their combat effectiveness.

The third-order zombies are more intelligent than the second-order zombies, although they no longer use weapons such as kitchen knives and steel bars, they can quietly hide in the shadows, suddenly attack, ambush humans, and even consciously find nearby human hiding places.

Therefore, it is almost impossible to hide in the city center where zombies are densely populated for a long time, the higher the evolution level of the zombies, the stronger the IQ recovery, and even when the zombies reach the seventh order, they can already track the human beings and find the human base camp hiding in the urban area.

Since most of the zombies of the Agricultural University were led to the east gate by Ye Feng, and the experimental building was close to the west gate, it was a lot more convenient for Ye Feng and the others to leave the Agricultural University, and Ye Feng was not looking for the heavy truck parked at the east gate.

Instead, he quietly sneaked to the parking lot near the West Gate, Agricultural University is a national 211 major university, the school leaders are naturally very rich, and there are many rich second generations among the students, so it is not difficult to find a good car.

Ye Feng and his party came to the parking lot near the west gate and found a square and domineering Humvee, and after a lot of rummaging, they started the Humvee.

After seeing Ye Feng's skillful and simple start of this Hummer, Chen Yalu's three daughters looked at Ye Feng's eyes, with a hint of complexity, as we all know, the current car, the anti-theft system is very advanced, even if it is a domestic car, it is no exception, especially a vehicle with a price of hundreds of thousands, it is almost impossible to start without a key.

Stealing a vehicle is not as simple as in the movie, jump in, touch the line and ignite it, but Ye Feng took less than three minutes from entering the Hummer to starting, this speed, this kind of technology, is completely comparable to the great master among car thieves.

If it weren't for Ye Feng being Bai Yao's classmate, these people would definitely think that Ye Feng had learned to steal cars since he was a child, and he was already a habitual thief, obviously the girls misunderstood Ye Feng, and the car stealing technique was almost one of the necessary skills for survivors of the end times.

After the Hummer was activated, Chen Yalu took a stance and rushed towards the west gate of Nongda, and then, under the guidance of Ye Feng, he drove towards the street with the fewest zombies.

Humvee is an American military car, excellent performance, full of horsepower, under the driving of Chen Yalu, encountered a small number of zombies, or as before, directly crashed into the air, encountered dozens of zombies, first with a submachine gun a burst of strafing, in the use of the Humvee to hit over.

Along the way, although I encountered several corpses, there was still a thrilling escape, plus the pre-detection route, the choice of the road with fewer zombies, and the detour around the city, after two hours, finally left the old town of Yashi and returned to the sea clouds.

After Ye Feng and his party got out of the car, Ye Feng first walked to the corridor, observed it carefully, and found that the trap placed in the corridor when he left did not appear abnormal, so he waved his hand with peace of mind and signaled everyone to enter the sea clouds.

The trap set in the corridor is not completely aimed at zombies, but humans, and this trap is not aggressive, but an early warning trap, as long as someone walks by, the trap will be triggered inadvertently, so that Ye Feng will know that someone has come.

Similar to this trap, Ye Feng also set some in other places, such as putting a toothpick on the door, as long as the door was opened, the toothpick caught on the door would fall, so that even if someone else closed the door anew, Ye Feng would know that someone had come.

After everyone returned to the sea and clouds, there was a feeling of returning home, Chen Yalu and the three daughters walked around for a while, and after finding no problems, they began to wash rice, wash vegetables and cook.

In the half month of farming, almost everyone has eaten compressed biscuits, and they have never eaten a hot meal, and now when they come back, they naturally want to cook a good meal.

Chen Yalu's three daughters cooked, Zhang Ying stood by the window to observe the surrounding situation, and Ye Feng entered the room, closed the door, and came to the windowsill of the room.

Standing by the windowsill, Ye Feng flipped his hand and took out a light blue, double-helix-looking DNA syringe from the space ring, this DNA syringe was naturally the extracted phagocytic gene.

Looking at the syringe in his hand, Ye Feng's face showed a hint of contemplation, Ye Feng was thinking about how long to inject.

According to the theory in the original universe, the earlier the phagocytic gene is injected, the higher the degree of fusion, because as the evolutionary continues to evolve, the body's genes are optimized again and again, and it has become very strong, and it will be very difficult to fuse the phagocytic gene, and even directly lead to gene collapse.

Human genes, in fact, are not perfect, with many defects, before the disaster, up to one-third of human beings have some genetic defects, such as common color blindness and color weakness.

Even those who do not exhibit two-thirds of the genetic defects do not mean that the body is perfect and has no defects, in fact, these defects are masked by dominant genes, because human DNA is a double helix structure, one from the mother and one from the father, and these two sets of genes are almost the same except for the X and Y differences about sex.

Everyone, regardless of whether there is a genetic disease, the gene will be defective, there are also strong and weak, even the dominant gene of the double eyelid gene, there are also sizes, some double eyelid genes through protein expression, so that the eyes are very large, very smart, on the contrary, some can express double eyelids, it does not look very large, completely similar to the single eyelid, that is, the so-called inner double eyelid.

Human evolution is to constantly optimize these genes, such as a color blind person who cannot distinguish between red and green, through evolution, will slowly repair the defective genes in the body, and finally completely return to the normal person, clearly distinguishing colors.

Repairing genes is just one of the benefits of evolution, the stronger the evolutionary, the more complete the body functions, after the human race reaches the three-star evolutionary, it is almost difficult to catch a cold, and it is difficult to infect the body with a common cold virus.

Samsung is not completely immune to the virus, if the blood containing HIV or Ebola virus is injected into the vein of the Samsung Evolutionary, the Samsung Evolutionary will not be immune, especially after the injection of the Ebola virus, it will still rupture the capillaries of the whole body a week later, turning into a puddle of pus and blood and dying.
