Chen Ning continued on the road, light brain field exploration, satellite terrain scanning, and the information obtained from the MCA in Bingtang for reference, Chen Ning's trip can be described as a smooth journey, very stable, day and night, six or seven days to reach the target area.

But the trouble is that in the energy response equivalent map explored by the light brain today, not only can many stout energy reaction points be found, that is, A-level and A+-level xenomorphs are located, but there are always pieces of energy collapse areas, that is, areas that cannot be observed.

Chen Ning was really walking on thin ice, frightened step by step, and his travel speed slowed down a lot. He needed to find his target's chemistry complex, but he didn't know where it was, and he had to search the area himself.

"Brush, brush!" Chen Ning turned his body for a week, and the light brain assisted his body to make the most precise movements, not missing the slightest, the light saber on the back of his arm skipped over the vital parts of several xenos around him, "kick", he retracted the light saber, his body stood firm, and the surrounding xenos fell to the ground.

He turned on the satellite phone with a worried brow, and the blue screen appeared in front of him, and after becoming a member of the club's executive committee, Ma Lunman opened the authority of the satellite earth for him, and there was another "map" for the module that the initial panel could choose.

He clicked on it, and a 1:50,000 scale bird's-eye view appeared on the blue screen, determining his position, and increasing the scale until it was 1:2000, the largest scale a satellite map could reach.

Chen Ning quickly pulled the map on the blue screen, he had been looking for this area for five days, and he had not found the slightest clue about the laboratory.

The map moved, but his face became heavier and heavier, and the energy response equivalence map mapped by the light brain in front of his retina overlapped with the satellite map in front of him, seeming to ...... Except for those energy collapse areas, he had already searched them all.

The general area must not be mistaken, Chen Ning lived and studied here for a period of time in his previous life, that is to say, now he has to try his luck in those places.

The arrow had to be sent on the string, although it would take a little risk, but Chen Ning felt that he could not run this trip in vain.

Entering the first energy collapse area, without the constant operation of the light brain and the energy response prompts, he felt that the atmosphere around him was different, a little gloomy and dangerous.

Walking vigilantly at all times, Chen Ning entered a thorny bush, hunched over, and suddenly, he saw a white bone spur through the thin slit between the bushes.

Looking closer, he saw the full extent of the bone spurs.

It was a strange creature lying on the ground, its body undulating, and it was supposed to be sleeping. At intervals on its entire middle spine, a long, sharp bone spur grows out, piercing the dorsal skin, its claws and thick fangs are equally sharp, its body is slender, three or four meters long, and its limbs are thick, one person is surrounded by thick and half a meter high.

Searching the memories in his mind, Chen Ning knew that this was an S-level force xenomorph long-bone dragon, and it was no one more troublesome than Lin Bei, anyway, it was not something he could deal with now.

He quietly retreated, and before dawn carefully searched the entire energy collapse area where it automatically blocked the optical brain energy analysis, but still found nothing.

Over the next few days, he began to go out day and night, taking advantage of the rest of the night to sneak into their territory to investigate.

It turns out that under the control of the light brain's movements, his hiding ability is still commendable, as long as he walks around carefully, he doesn't provoke any xenos to avoid disturbing the biggest boss, and it's basically no big deal.

At this time, Chen Ning, who has a unicorn arm, has his own combat power of about A+ level, so it is no wonder that he can do this.

Finally, the hard work paid off, and he was determined to enter the sixth day of the energy collapse area, and when he searched the territory of the sixth S-rank xenomorph degree kite, Chen Ning finally made a discovery.

Between several large stones, a rusty and mottled iron plate with an area of one square meter lies quietly, and some characters that have long been blurred are engraved on it. Its surface is somewhat uneven, which was not the case at first, perhaps due to the changes in these years.

Although according to the memories of his previous life, this chemistry laboratory was definitely one of the best-preserved in the last days, Chen Ning couldn't help but feel a little apprehensive at this time.

Du Kite is an S-level xenomorph of the wind genus, more than 30 years after the beginning of the end of the world, the xenomorph only relies on its own strengthening, even if the starting point is high, it is rare to reach the S-level or S+ level at this time, at most, it is just to rely on talent to forcibly enter the S-level big rank, as a bottom S-class.

Of course, no matter how bad they are, they can easily crush Chen Ning to death, so Chen Ning's movements are still very small now, and he doesn't dare to take a step beyond the thunder pool, lest he attract the attention of Du Kite, I'm afraid that it can come to his side in the blink of an eye, and one move is instantaneous.

After cleaning the surface of the iron plate, Chen Ning finally found a small gap at the edge of it with his memory, opened it, and the rusty door shaft made a "squeak" sound, which was especially harsh in the silent night.

He scanned the surroundings, there was no abnormality, the movement quickly slowed down, and the "squeak" sound became smaller, and after three minutes, he was sweating profusely and finally let the small PIN pad under the iron plate be exposed in the air.

Chen Ning's eyes flashed with joy, he closed his eyes and remembered for a moment, and reached out to type on the keyboard.

The password is divided into 6 groups, each group of passwords is 12 digits, 14 digits, 10 digits, 8 digits, 16 digits and 12 digits, the order is fixed, and the six sets of passwords are respectively controlled by the 6 scientific researchers in this laboratory before the end of the world, just because this is the permission password to force access to the laboratory, which is very important.

It is precisely because of this that 12 years after the end of the apocalypse, human beings have enough technology to forcibly crack this set of passwords, thus opening the passage into this chemical laboratory, and Chen Ning happened to be quite interested in this matter at the beginning, and memorized this set of extremely complicated perverted passwords with numbers, English case and upper and lower case, and various symbols mixed with each other.

"Drip ...... The permission password input is successfully verified, please wait. ”

A mechanical sound came from the keypad, echoing in the air, and the sound was not loud, not too far away.

Unlike 587, this chemistry laboratory has a higher specification, and even has an AI butler to manage it in real time.

"Hiss-" The junction between the rusty iron plate and the ground erupted a stream of air, and then the iron plate slowly rose up to a height of about 10 centimeters, and the mechanical sound sounded again:

"Permission passed, Laboratory Exit 1 opened, Chemisman at your service."

"Humph!" Chen Ning put the keypad back on, then clasped his hand to the gap between the iron plate and the ground, lifted it up forcefully, and jumped into it with a shrunk body.

"Close Exit 1." He shook his clothes and said lightly.

"Yes." The mechanical sound echoed in the laboratory, "Hiss-", and the iron plate slowly fell again until it was tightly sealed against the ground.
