"It's amazing. Pen, fun, pavilion www. biquge。 info "Zhang Xiaofan looked at the drop of black liquid, he couldn't have imagined that he could become like this, that is to say, the black liquid still has a way to be eliminated, from the previous teaspoon to a drop, which has made great progress.

"What is working?" said Zhang Xiaofan as he looked at the drop of black liquid strangely.

And then it didn't last long, and suddenly the black liquid returned to its original shape, and it was far twice the size of the previous teaspoon.

"This is ......" Zhang Xiaofan was surprised: "This is a positive derivation?"

There is a kind of cell that has the ability to make itself larger by swallowing some food, scientists call this positive derivative technology, which is currently being conquered, if humans master this technology, then they can use positive derivative to treat injuries and diseases that have broken legs on the battlefield, workers whose fingers have been strangled by machine tools, and patients whose skin has been disfigured, these people, they only need to eat some food to be able to return to their previous appearance, which can be described as a technology for the benefit of mankind.

However, it is very difficult to artificially have positive derivation, because this ability belongs to single-celled organisms, and humans have never found that a second life form has this kind of positive derivation ability other than cells.

Now, Zhang Xiaofan saw the existence of positive derivation on the black liquid, and he made him very worried in his heart, with this ability, if that alien life began to eat, then his volume would increase infinitely, and the nanowall besieging him would become like a toy, and he would no longer be able to pose a threat.

"It's been locked up for more than a year, and that alien life has no tendency to get bigger, it seems that either he doesn't know that he still has this ability, or he hasn't eaten. Zhang Xiaofan thought in his heart.

And the puddle of black liquid rose to the size of a fist, and the growth trend slowly stopped. But that's scary enough, knowing that he only had a teaspoon at first.

"I can't feed him anymore, and if the volume continues to grow, there will be unpredictable unknowns, and at this time, I really hope that humans have mastered negative derivative technology. Zhang Xiaofan sighed.

There are positive and negative, negative derivative technology is the inspiration that scientists get from positive derivation, which is to extract nutrients from the body of the object, so that it is infinitely obscene, such as tumors, varicocele, internal cancer This complex and intractable disease, after using negative derivative technology, their growth progress can be infinitely suppressed to achieve a pseudo-curative effect. Although it is a pseudo-cure, it is sufficient, and the negative-derived technology can suppress the tumor without deterioration for at least a hundred years, and by the time the tumor does worsen, the patient will already be dead.

Positive and negative derivative technology has always been the highlight of the research of the World Academy of Medical Science and Technology, and every day there are hundreds of scientists around the world working hard for the birth of positive and negative derivative technology, once successful, it will benefit thousands of patients.

Zhang Xiaofan took a box made of titanium, silver and tin and put it on the table, and directly used a nano glassware to knock the black liquid into it and lock it.

"Let's put it there for now, I can't study anything for the time being, I'll look at the corner specimens of this thing, if I can find any new breakthroughs, it would be perfect." Zhang Xiaofan said to himself, and then immersed himself in research.

......

Shen Mo looked at the chariot with some curiosity, if he really wanted to solve Sophia's group, he could have directly called all the hosts and overturned this chariot, but for the sake of fun, he passed the boring time of the space fleet in front of this planet, which was on par with Sophia and the others.

"The technology of human beings on this planet is much more advanced than that on the other side of the earth, and there are so many new technologies that can only be seen in science fiction, if I can occupy it, it will be much more convenient. The cockroach host silently attached to the chariot thought to himself.

The chariot has been moving forward, and the purpose of Sophia and the others now is to slaughter any monster they encounter on the road, and all the creatures they see are slaughtered, Li Muyun is originally a battle maniac, and Sophia's mission is exactly what he meant.

But the strange thing is that there are not many monsters along the way, as if they are all hiding, which makes Sophia and her party very puzzled.

"What's the situation? I can't even touch a monster. Li Muyun said with some irritability.

"What's the hurry, Hangchuan City is so big, it's possible that we just didn't meet it. Leng Yue shook her head and said, this Li Muyun is so impatient, how did he get selected as an agent in the first place?

"Hmph, boring. Li Muyun Erlang's legs were cocked, and he was speechless.

Hangchuan City was a first-tier city before, naturally there was an underground power grid and underground nuclear sources as the city's energy supply system, after the nuclear bomb explosion, these things were all prompted by the nuclear explosion, ground radiation and electromagnetic pulse and landslides are very many, it can be said that the entire Hangchuan City has become hell.

It is very difficult for a chariot to travel in such a place, and it is always exposed to danger from underground.

"The two monsters underground are also gone, and the radiation detector has detected a lot of excessive nuclear radiation nearby, so it is not appropriate to leave the chariot. Leng Yue looked at the screen and said.

"Well, got it. Sophia nodded, after experiencing the dragon dust, everyone knew that kind of monster would always come out of the ground and kill people, so leaving the chariot was a very dangerous behavior.

......

"How do you plan to solve the matter of Hangchuan City?" Yanhuang City, the Supreme Council, the eight top leaders gathered in this place to discuss matters related to Hangchuan City.

These eight leaders are the top leaders in the eight industries responsible for officials, military, economy, construction, public security, foreign affairs, logistics, and specialty, and they can be regarded as the highest positions in the country.

"Isn't it already blocked, hasn't the alarm been lifted yet?" asked Diplomat 1 in a loud voice.

"According to the report provided by the Secretary of Defense, that extraterrestrial life was not greatly affected by the nuclear explosion. Special 1 replied.

"How the hell did this thing come to us, why didn't the Ministry of Space feel it at all, this is a serious dereliction of duty!"

"Hmph, we don't know anything about extraterrestrial life, how can we blame the Ministry of Astronautics for this? Extraterrestrial life is inherently mysterious, and it's normal to be a smuggler. Military No. 1 said lightly, as a department for the defense of the country, this matter has evolved into what no one wants to see now, and no one is comfortable.

"Don't quarrel, don't blame each other for this matter, it's all for the country, let's discuss how to solve this alien life. "Economic No. 1 persuaded, a Hangchuan City was destroyed, but it was his Economic No. 1 who was injured, only he knew how much money the country spent on the development of Hangchuan City into a first-tier city.
