Different from the tragic battle outside the city, at this time, in the depths of the earth, in a top laboratory, countless scientific researchers in white coats are crazy busy, almost the entire elite of Huaxia Kingdom is gathered here, and it is not difficult to see a few foreign faces, they have been working overtime for seven days in a row, red eyes and black circles, everyone is tired.

"The 302nd test failed, and the rabies virus could not cause effective damage to the cells of this xenogene. ”

"The three hundred and third trials failed, and Bacillus anthracis was unable to effectively damage the cells of this xenogene. ”

"Three hundred and four failed attempts, Yersinia pestis was unable to cause effective damage to the cells of this xenogene. ”

......

"These damn silicon-based creatures!"

"Every piece of data must be carefully recorded, except for those lethal germs, viruses, and other attempts should not stop!"

Dai You looked at the tube in front of him, which had consumed two-thirds of the blood, and a trace of sweat oozed from his forehead.

This tube of blood was extracted by Dai You from Beixing's body, and at that time, he joined forces with the Azure Squad to repel Chen Mo and his party, and also eliminated the Queen Bee, and gave an extra package drawing to the Azure Team.

Now it is certain that the northbound is also the alien alien species, I don't know what method was used to blend into the famine world, and ambushed, and then according to the information left by Menil, this northbound is at least the existence of the fourth-order peak, the high-level among the aliens, and the bloodline is noble.

The fourth-order peak is obviously already stronger than the existence of the four-winged xenomorph, you must know that the northward movement of the fourth-order peak at that time was still in the famine world, and it was also suppressed by part of the famine rules, and the real strength is likely to be the existence of the fifth order, or even above.

Unintentionally planted willows, willows are shady!

In the face of such a distinct class of xenos, it is definitely a very difficult thing to get the blood of the high-level xenomorphs of the northbound species, and now, it is this tube of blood, which has become the most precious thing in the hands of human beings to deal with that xenomorph.

Failed again! Although Dai looked calm at this time, he also began to become anxious, could it be that he was in the wrong direction from the beginning?

Is it really not feasible to use high-level alien blood to develop biological and chemical weapons that are only effective against silicon-based life, so as to achieve a blow to the entire alien race?

"Sir Dai, there's a new discovery from the Ergonomics Department!" Dai You was still pondering, when a voice broke Dai You's thoughts.

When I came to the ergonomics laboratory, everyone here was stunned to look at the picture on the big screen opposite, with a long mouth and a look of disbelief.

I saw that on the screen, a strange cell was rapidly devouring the cells around Tonghua, and was constantly growing its strength, and then these weird cells were more and more, and more and more unstable, looking extremely irritable and aggressive.

The injection of white blood cells in the human body into the northbound blood directly led to the mutation of a very small part of the cells in the northbound blood, resulting in the production of extremely rare emerging virus cells.

Dai You's eyes burned as he looked at the four-winged xenomorph in the cage of the experimental vessel full of pain, and a strange smile appeared on the corner of his mouth, he had found what he wanted.

Dai You was very decisive and began to assign new tasks to his scientific researchers.

A small team tasked with strengthening the airborne transmission of the 'Trial' cells and increasing airborne survivability.

Team 2 is responsible for increasing the cellular activity of the 'Trial' cells, increasing their resistance to cold and heat.

Three squads are tasked with increasing the additional infectivity of the 'trial' cells while reducing the likelihood of the virus being detected in the early stages.

Team 4 is responsible for increasing the destructive ability of the 'Trial' cells, so as to quickly cause xenomorphs to be incapacitated by the virus until they die.

Team 5 is responsible for ensuring that the 'Judgment' does not have any effect on the human body, and that it is only spread among silicon-based life.

.......

Then the entire research institute began to run at a high speed again, but at this time, everyone's research had been replaced by the study of that emerging virus cell, which was still too weak, and needed to be strengthened and upgraded.

Trial I..... Trial II.... Judgment III... Trial IV....

The physical fitness of human beings is far inferior to that of xenos, and there is no comparison, any two-winged xenomorph can easily kill nearly a hundred strong men, but humans are not powerless to fight back, and humans have technology!

Armed with the power of science and technology, human beings are far more difficult to deal with than the natives in the famine world, a strategic nuclear bomb is like a full-strength blow of a fourth-order master, not to mention a hydrogen bomb, an atomic bomb, and even a fifth-order master's full force of a single blow, but these are strategic forces after all, and they cannot be used for conventional strikes.

Nowadays, when human beings are facing a desperate situation, the power exerted is even more endless, just like now, the 'judgment' virus is evolving at a speed that ordinary people cannot understand, I, II, III, IV originally evolved to this extent in nature without millions of years would not have been possible, but with the joint efforts of countless top scientists, everything is so expected.

......

At this time, the battle outside CQ City did not end, but became more tragic because of Ling Hong's appearance, the xenos obviously did not expect that there were still fifth-order existences among those humans whose general physical fitness was in the early stage of the first order, and they were also blinded for a while, and a large number of xenos died in the hands of Ling Hong in pieces, and the bones were gone, until the appearance of a higher-level xenomorph king.

A face that was almost indistinguishable from a human being, except for his eyes, dark green eyes, and a height of two meters floating in the air, indifferently ignoring Ling Hong, exuding an incomparably powerful aura on his body.

Mid-fifth-order! This xenomorph in front of him is definitely the mid-fifth-order! Ling Hong is almost sure.

"Killed so many shrimp soldiers and crab generals, big fish, finally come out, you are the king of xenos, right?"

I don't know why, Ling Hong felt that the strange man opposite should be able to understand his words.

"My Wang... Lack is... Can you Ulu... of, I am six.. Six Commanders!"

Several intermittent harsh voices came from the mouth of the demonic strong man, the accent was a little strange, which made Ling Hong very uncomfortable to hear, it seemed that the northbound Chinese was better among those aliens, Ling Hong was a little depressed.

“can.. Chinese?"

“%@#！”

The demonic strong man suddenly looked confused, and then his face darkened, and he reacted that he had been ridiculed, by a human being in the early stage of the fifth order.

Seeing that six wings suddenly grew behind the angry xenomorph strong man, Ling Hong also put away his joking expression, ready to come for real.

Although Ling Hong at this moment is in the early stage of the fifth order, he has already completed the transformation of all-attribute magic, and his real combat power is close to the middle of the fifth order, coupled with the help of weird time magic, space magic and ability, Ling Hong is now seven points sure of killing this six-winged xenomorph in front of him!
