Qin Yan leaned back against the wall and looked back vigilantly.

The overturned green potion flowed out of the broken test tube bottle, and a huge black cat squatted next to it and stared at Qin Yan, his eyes were fierce and vigilant, as if he could pounce and bite him at any time.

This is a mutant cat.

Like those venomous spiders, they are all affected by chemical agents.

Qin Shi asked Pikachu, "How many such creatures are there nearby?" ”

Pikachu turned on the long-range infrared function and surveyed carefully: "Master, there is one outside the window on the first floor and one on the third floor." ”

These mutated creatures rely primarily on sound and smell to determine unknown dangers.

The longer you stay here, the more likely you are to attract more creatures nearby.

The spray also has a limited duration of action.

Qin Yan almost immediately made a judgment, quickly and accurately fired at the black cat, and the moment the mutant cat heard the sound outside the window, he turned the direction of the muzzle and accurately shot it in the head.

The whole process is beautiful and smooth, and it only takes a few seconds.

Pikachu wow: Handsome!

The laboratories on the first and second floors found nothing, and after turning from the balcony to the third floor to deal with the other mutant cat, Qin Xian took a bottle of well-preserved elixir.

As soon as he got up to the fourth floor, he smelled a foul smell that was stronger than before.

Qin Yan took out the medicinal herbs that Ming Yu stuffed for him, picked a leaf and swallowed it, put on his mask again, and then raised his gun and kicked open the door in front of him.

From the fourth floor to the seventh floor, the whole is opened up to form a huge open space. As far as the eye can see, the green mist lingers, rushing to the top floor.

This is probably Dr. Satsu's core research institute.

Pikachu is the most powerful new generation of intelligent optical brain in the entire interstellar except for the master control optical brain, and it took less than a moment to analyze the gas composition: "Master, the gas concentration here is highly similar to the concentration of acid rain, it should be that after the gas evaporates, it enters the atmosphere and gradually forms acid rain." ”

A large number of chemical agents leak out of the laboratory, causing biological mutations, and some of the slowly volatile liquids accumulate over the years into harmful gases that destroy the atmosphere.

2395 is the closest to Planet X, and once again unlucky.

If the source is not solved, the acid rain will not stop, the protective shield will be damaged, and the entire 2395 will face a major disaster.

"Master, the concentration of toxic gases here is too high, and the effect of gas masks is not strong, so you better go out first." You........ Eh, why are you okay? ”

Pikachu, as Qin Yan's light brain, has the main task of keeping an eye on his health at all times.

After checking that he was not affected by a trace of poisonous gas, even the senior light brain was stunned: "Master, your physical fitness is also amazing." ”

“..........”

Qin Shi: "Don't sell cute, disgusting." ”

Tough guy Pikachu: Huh~

Raising his hand and waving the dense fog in front of him, Qin Yan saw the potion scattered on the ground, sprinkled the dissolving potion that Professor Qin gave him on it, and waited for the gas to gradually dissipate.

This process lasted about an hour, and the blue fog faded so that the outlines and equipment of the entire space could be faintly seen.

Dr. Satsune should have put a lot of effort into establishing his experimental kingdom in the first place.

Qin Shi didn't know much about Zuo Xun.

I just heard Pikachu babble a few words before he came, saying that he was a scientific madman who had spent his life trying to study genetic mutations. As a result, a few years ago, I didn't know what an accident caused the laboratory to explode, and since then, he and the entire people of Planet X have all disappeared, most likely dead, and then left behind a bunch of harmful things, causing biological mutations.

Now it's even more of a problem for 2395.

But by some definition, his genetic research experiments were successful.

While waiting for the green mist to dissipate, Qin Xian made a round around and noticed that there was a very special design above the top floor of the seventh floor.
