The towering iron thorn net separates the inside and the outside into two worlds. The outside is lined with an orderly but insensitive criminal puppet army, while inside there are chilling screams from time to time.

This is the first time that Gu Chen has come to the research institute of the Ministry of Industry in a serious manner. Although he has heard about the inhumane research here, he still feels uncomfortable instinctively when he goes all the way.

On the way, he saw the skinned aliens, who were randomly hung on the iron wire net like animals.

He also saw hundreds of millions of aliens in a crystal. They lived in a small world and struggled against natural disasters, but they didn't know that the researchers from the Ministry of Industry were recording their lives and deaths while talking and laughing.

Life in this place seems extraordinarily cheap.

With a blank expression on his face, Gu Chen quickened his pace, and soon came to Kong Sheng's exclusive research institute.

"Please inform Fellow Daoist Kong that Gu Chen is visiting."

After explaining to the guard at the door a few times, Gu Chen waited beside him.

Not long after, I saw a green-haired Kong Sheng walking out quickly, and when he saw Gu Chen, he seemed very enthusiastic.

"Brother Gu, when I heard that you were released from the prison planet, I was happier than anyone else."

Kong Sheng exchanged pleasantries, as if he and Gu Chen were really brothers, and wanted to put his arms around his shoulders to show his closeness.

Gu Chen moved his position calmly, kept his distance, and spoke with a smile. "Fellow Daoist Kong should know the reason for Gu's visit, right?"

"Of course I know, Fellow Daoist Ouyang has already told me."

Kong Sheng was grinning, and didn't mind Gu Chen's alienation, and waved to him.

"Come, come! I'll give you a good introduction, just tell me what kind of weapon you need."

Gu Chen then followed him into the research institute, and under the introduction of Kong Sheng, he started to visit around.

There are many research institutes of the Ministry of Industry, and most of the other research institutes are jointly owned by many researchers, while Kong Sheng, the head of the Ministry of Industry, owns one building alone.

Kong Sheng's research institute looks much cleaner and more comfortable than other places. It is divided into upper, middle and lower floors, and the layout looks very open.

There are many huge glazed pillars in the hall on the first floor, and there are all kinds of things in the glazed pillars, which can even be called bizarre things. It seems that they are specially placed here for people to watch.

"The displays on the first floor are all my mature works, many of which have been used in practice. Brother Gu needs to choose weapons for his trip to Lei County. I suggest you choose them here." Kong Sheng said.

"I don't know which weapons here are more suitable for this mission?" Gu Chen looked around and asked casually.

It is true that many of those glazed pillars are weapons, but there are also some that are too different.

Gu Chen even saw the corpses of aliens soaked in the solution in some glazed pillars, and it was difficult to figure out their abilities and power.

"Hehe, it's boring to tell Brother Gu directly, why don't you take a guess?" Kong Sheng blinked.

"Gu's eyes are clumsy, I'm afraid I can't recognize it."

"Don't be afraid, don't be afraid, little brother Gu just give it a try, there will be rewards." Kong Sheng said mysteriously.

"Reward?" Gu Chen's eyes showed doubts.

"Under normal circumstances, he will apply for a weapon from me with the position of General of Heaven's Punishment. I will allow him to bring out one weapon at most."

"But if his eyesight is strong enough to identify the three most valuable killing weapons from here, I will allow him to bring out one more, or even choose among the three most valuable killing weapons."

Kong Sheng explained that this is a small game rule he made, and everyone in the criminal world knows it well.

"I see."

Gu Chen suddenly realized, and then smiled wryly. "There are so many exhibits here, it is really difficult to pick out the three most valuable killing weapons."

"It is precisely because of this that the reward is worthwhile. How about it, brother Gu, do you want to give it a try?" Kong Sheng asked expectantly.

"Of course we have to try."

Gu Chen nodded, not to mention whether the weapons here are against the harmony of heaven or not, but the lethality is genuine, it is helpful for his mission this time, so it is natural that he can bring one more item.

"Then please."

Kong Sheng stepped aside and watched Gu Chen choose a weapon with a smile on his face.

Gu Chen's consciousness spread out immediately, trying to sense the strength of each weapon's energy, but unexpectedly, when encountering the glazed pillar, his consciousness bounced back one after another!

There was surprise in his eyes, and Kong Sheng beside him said something. "Spiritual consciousness cannot see the true value of these weapons, it depends on eyesight."

Gu Chen kept silent, retracted his consciousness, and the next moment, his pitch-black eyes slowly turned into deep purple, and there was even a faint flash of lightning.

Shinto, deep sea purple pupil!

After Gu Chen's original Ziji pupil integrated the ability of seeing and hearing the divine body, his ability in sensing became very powerful.

And after he absorbed the origin of the Emperor of the Sea, he even indirectly obtained one of his pupil skills, called the Deep Sea Seeking Light Pupil.

The world where Neptune lives is full of vast oceans, and most creatures live in the dark and bottomless deep sea.

The Sea Emperor was born with a pair of deep-sea light-seeking pupils, which can help him capture the energy fluctuations of any living beings in the deep sea.

Within the line of sight of his deep-sea light-seeking pupil, the energy in all living things will glow. With the help of this pupil, he can easily judge the enemy's strength and physical condition.

It was through the magic of these pupils that the Sea Emperor rose up when he was young, and eventually grew into a world emperor.

And after he reached the Emperor Realm, this innate eye pupil was also sublimated to the extreme, and he transformed it into a pupil technique that can spy on the origin of others.

When Gu Chen absorbed the origin of the Sea Emperor, he accidentally obtained this pupil technique. After more than half a year of practice, he successfully fused it with the abilities of Ziji pupil and Wangwen divine body, turning it into a powerful pupil technique.

And because of the integration of the deep-sea light-seeking pupils, the color of the pupils became pure dark purple when the technique was performed, which was very similar to the original Ziji pupils.

At this moment, when Gu Chen cast the Deep Sea Purple Eyes, the many glazed pillars in front of his eyes suddenly underwent unusual changes, and the weapons inside released light of different strengths and colors.

What he couldn't see with his spiritual sense before, he saw clearly at this moment!

"Sea Emperor's pupil art is really unique. After improvement, even if there is a restriction, the strength of the original power inside each weapon, and even what kind of origin they belong to, can be clearly seen."

Looking at the many weapons with obvious strengths and weaknesses, Gu Chen secretly said in his heart.

"Brother Gu, why is he standing still? You can walk around and have a look." Kong Sheng reminded Gu Chen when he saw that Gu Chen hadn't moved for a long time.

Gu Chen subconsciously glanced at Kong Sheng with his deep sea Ziji pupil, and the pupil suddenly shrank like a needle!
