Gao Xianda walked out of the house carefully with a gun.

He looked at the exit and then looked at the depths of the room. The underground base didn't look very big, and there were several rooms. So Gao Xianda decided to explore it briefly.

Gongsun Yu has built such an underground base here, and I don’t know if he has any intention. He can’t go to any underground base when dealing with King Su. Even if he wants to raise soldiers, he will not be placed in this dark place.

So Gao Xianda walked in. The first one was a simple dormitory. There were four iron beds with upper and lower bunk beds, which could accommodate eight people.

But there was no one inside, so Gao Xianda walked towards the second room.

The second room turned out to be a laboratory, with glass embedded on the tight iron doors, which allowed you to see what was happening inside. There were four people in white coats busy there nervously.

There are various materials placed on the tables in the house, including metal, ceramic, rubber, etc. They are conducting various tests on these materials.

Pressure test, corrosion resistance test, tensile test... one after another, meticulously done. Next to it, there is a stamping hammer repeatedly hammering a piece of experimental material, making huge noise.

Gao Xianda didn't know what they were doing, but he actually ran to such a dark place to do an experiment.

Gao Xianda ignored them and continued to walk towards the room behind. The third room was also a laboratory, and there were four people doing experiments.

However, it seems that the experiments they did were slightly different. The table was filled with instruments such as test tubes and beakers, which contained various colors of liquids. They carefully blended the different liquids, left them to stand, observed, and recorded them in detail.

Some people also put part of the mixture into special instruments for oscillation or heating.

Some of the blended liquids are very stable in the bottle, some begin to bubble violently, and some even explode because of the reactions that are too violent.

However, they seemed to be accustomed to explosions. The operators had equipped protective measures in advance. After the explosion, they recorded the relevant data and cleaned up the garbage, and then began the next experiment.

Explosions occurred very frequently. Gao Xianda took a look at them and encountered two different explosions.

The two people in the laboratory, one was listening to the sound of irons and the other was listening to the bang explosion. No wonder they were not too shocked by the fact that Gao Xianda threw five grenades in the house just now.

I guess they all thought it was a big news caused by the laboratory next door.

Gao Xianda continued to walk inside, and there was only one last room left.

This room is different from the first two, and there is no glass door on the door that can be used for observation.

As soon as Gao Xianda came over, he heard a sound of footsteps coming from inside. He pushed the door and walked out from inside.

He was wearing a mercenary costume and a gun around his waist. When he saw Gao Xianda standing in front of him, he was stunned.

Gao Xianda's reaction speed was faster than that of him, and he directly pushed the "grenade enthusiast" to his head.

"Don't move if you don't want to die!" Gao Xianda warned.

The mercenary was obedient and quickly raised his hands to express his surrender.

"Tell me, what's going on here?" Gao Xianda said, "I'll tell you first, I can tell you if you are lying. If you lie, you will be dead!"

"Yes, yes!" said the mercenary, "What do you want to ask, just say. I will tell you what I know, please don't kill me!"

"Where is this place? Who built it? What do those two laboratories do?" Gao Xianda asked.

"This is an ordinary basement..." said the mercenary.

The black panther jumped out of the corner and rushed towards the mercenary.

But the mercenary seemed to be unable to see the Black Panther.

Gao Xianda moved his gun directly downward and shot him in the thigh.

The power of the "grenade enthusiast" is really great. This shot suddenly blew the mercenary's thigh!

The mercenary was unable to stand firmly and sat back into the door.

Not only did he hurt his legs now, but his butt hurt, and soon, he felt the pain of the black panther scratching his face.

"I said I can tell if you are lying." Gao Xianda said, "If you don't tell the truth, you will die soon."

"Yes..." The mercenary was no longer as cheerful as before. He seemed to be thinking about how to say that he could deal with Gao Xianda.

"This is an underground laboratory built by Brother Prostheus." said the mercenary, "helped him study things."

Prosut is Gongsun Yu.

As the mercenary finished speaking, Black Panther immediately stopped attacking. However, many blood marks had already been rumored on the mercenary's face.

"Very good, continue," said Gao Xianda, "what is studying?"

"I don't know... I really don't know!" The mercenary voice burst into tears, "These two laboratories are the people he hired to do experiments. What kind of experiments they did, I really don't understand, the big-headed soldier! They are all very high-tech things anyway. I talked to the scientists that their rewards here can make it as good as those who work outside for a year. That's why they willingly do bullshit experiments in this dark place. If you want to know, just catch a scientist and they know everything!"

"Okay, you've passed the test." Seeing that Black Panther didn't take action, he nodded, "How many bases are there like this? How many mercenaries are there?"

"I don't know how many bases are. I'm the only one here anyway." The mercenary said, "but there are 131 people in our mercenary team. They are all hired by Brother Prostheus."

"One hundred and thirty-one people..." Gao Xianda said in his heart, "This team has a lot of people. According to large numbers, even thirty people were killed in the arsenal; even twenty people were killed in the underground of Ni Ao's apartment; not counting the coward in front of him, then Gongsun Yu should have at least eighty people under him. If only one person is required to take care of such a laboratory, then what have the other eighty people gone to do?"

"What are the rest of the people doing?" Gao Xianda asked.

"Sir, I really don't know. Please, let me go!" said the mercenary.

However, this time it caused a commotion from the Black Panther. On the verge of attack, Gao Xianda stepped on the wound on the mercenary's leg with his foot and said, "I know what to say."
