The source of the vines could already be seen in the distance, as if they were growing directly in the Nile, Lin Zifeng and the others followed the vines to the bank, and sure enough, all the vines extended from the Nile.

"Who are you?"

Lin Zifeng and the others were still looking at this strange thing, and suddenly they heard someone calling them, speaking in English.

Lin Zifeng and they were stunned, because there should be no one in the city anymore, and when they turned around, they saw a black man in a suit and leather shoes.

"We were passing through, out of curiosity, to come and have a look. Cai Bing turned his head and said to the black man. But before he could say a few words, Lin Zifeng interjected.

"Are you Professor Dan?" Lin Zifeng finished speaking, and everyone looked at Lin Zifeng.

"Do you know him?" Xue Qiang asked beside him, but before Lin Zifeng could speak, the black man said.

"You know me?"

"Well, I've read your papers, and I've read your materials. Everyone looked at Lin Zifeng suspiciously.

"This is a well-known professor of botany, and he is now a companion to us, and he is now using his knowledge to improve the environment of the Sahara Desert, and I hear that some results have been achieved. Lin Zifeng spoke in Chinese, so the black professor did not understand, and then Lin Zifeng explained what he just said to the black professor, and the black man heard Lin Zifeng say that these people were actually walking with him, and the serious and vigilant expression on his face was swept away, and turned into a smile.

"Come with me. After saying this, the black professor turned around and left, and Lin Zifeng and the others followed.

Not long after walking, several people came to a luxurious house, where a small generator worked all day, the room was brightly lit, the black professor beckoned everyone to sit down, and also took out food to entertain Lin Zifeng and them, in addition to the black professor, there was also his wife and a beautiful black daughter, the black professor was afraid of Lin Zifeng and they were polite, and they ate with them, and also took out a few bottles of good wine, and shared them with Lin Zifeng.

After talking about it for a while, I found out what happened, on the second day of the dark energy outbreak, everyone in this city woke up from a coma and was attacked by the beasts of the Nile, because of the huge number and continuous flow, so the local government organized an army to escort people to other cities, and the city became an empty city, and the black professor was entangled in another thing at that time, so he stayed here.

The black professor was originally a botanist, and then he thought of improving the environment through plants, and after many years of research, he finally researched a plant, which can make sand into fertile soil by secreting a special liquid, but the efficiency is not high, and it takes a huge amount of money to plant this plant in large quantities, so there is no country or organization that is willing to pay this money, and the professor has always wanted to strengthen the characteristics of this plant through his own efforts, so that the country or organization can spend money to plant this plant in large quantities and improve the environment of the desert, but it has not been successful, and the black professor also took out a pot of soilThe professor said that this was originally a pot of sand, but now it has become soil, and it is very fertile, that is, it needs a lot of mineral water, and it takes a long time, and everyone is very shocked that it can cultivate this plant, which is really amazing. But later, this plant actually mutated, just after the explosion of dark energy, the day the black doctor woke up, he found that this plant actually moved, it was originally a vine plant, and now it is scurrying around in the ground with its vines like feet, like an octopus, but it is indeed just a plant cultivated by the black professor, this plant is not aggressive to humans, the professor grabbed him, and it wrapped around the professor's arm, as if to show intimacy to the person who created it, but this thing became particularly dependent on water after the transformation of dark energy, and it withered after a while, and the black professor put it on the ground and poured some waterThe plant's ability to change sand into soil seems to have been greatly enhanced, and after a while, the surrounding sand became soil, but it was not fertile, but at this moment, suddenly a wild beast launched an attack on humans, and crocodiles and black beasts like baby fish also emerged from the river, because the black professor's laboratory was very close to the river, so it was also attacked, at first there was only a black beast attacking the laboratory, the beast broke the window and jumped into the black professor's laboratory, and began to destroy, the black professor was about to attack the black beast with a baseball bat, but he didn't hit, and was scratched by the black beast on the armBut when it continued to attack the professor, it was suddenly entangled by the previous vine plant from behind, and the tip of the vine pierced directly into the body of the beast, and after a while, it was sucked dry of blood and fell to the ground, and then the vine walked to the professor's side, and a liquid seeped out from the vine, and applied it to the professor's injured arm, only for a moment, the blood stopped, and then healed at a speed visible to the naked eye, and the vine wrapped around his arm again, as if to protect his master, the black professor looked at the plant that saved his life, and his heart was full of gratitude, and for the next few days, the plant was like the protector of this laboratory, blocking all attacking plants.

After a few days, the people outside evacuated the city, because there were so many beasts here, ordinary guns could not form a limited damage to the beasts, and in order to avoid the beasts, everyone had to choose to leave the place where they had lived for many years.

When the black professor walked out of his laboratory for the first time, there was no trace of anyone on the street, only some wild beasts were gnawing on people's corpses, and in the next few days, the black professor had been cleaning up the wild beasts in the city, and the vines were really powerful, as long as the wild beasts were in front of it, there was no other way to go except to escape, there was no human population in the city, there was no blood of the wild beasts, and the vines dried up quickly, and the professor had no choice, so he put it on the bank of the Nile, so that it could have water to draw, and the professor accompanied it on the bank for several days, and the vines grew day by day, and the roots of the vines seemed to have evolved a mindOne day the professor's mouth became dry and cracked because of the long sun exposure, the vine seemed to see this situation, a vine spread over, put it to the professor's mouth, came a small mouth, the water in the body flowed into the professor's mouth, the professor felt particularly cool after drinking, and the chapped lips also improved, the professor felt amazing, this plant was originally cultivated to improve the environment, and now it has the effect of filtering the water source.
