Shen Zifeng and another prisoner followed the Heavenly King Masked Man out of the underground cell and came to a relatively spacious corridor.

"Oh my God, why is it so quiet here?" the yellow-haired man asked uneasily.

"Now those guys have gone to rest, and there may be no one in the lab!" The Celestial King Masked Man explained to the two.

"Dare to ask where the master is sacred?" Shen Zifeng asked.

"Who is sacred, it's not that I want to help you, it's that I see Lu Yu unhappy!" The Celestial King Masked Man explained.

"Look at Lu Yu's upset, do you have any deep hatred with him?" Shen Zifeng continued to ask.

"That's not the case, you don't know, the competition is quite fierce now, and his laboratory alone is unbelievable!" The Celestial King Masked Man replied.

It didn't take long for the three of them to leave the aisle and come to a laboratory with a very large space, the scale of the laboratory was comparable to two football fields, and the people who built this laboratory should have spent a lot of manpower and power.

"It's just a laboratory, and this group of WBDs is so luxurious!" The blonde man complained.

"I'm not surprised that they can do such a thing!" Shen Zifeng said that this situation could not be more normal.

"Where's the lab exit?" the blonde man asked, "How long will it take to get out?"

"Let's walk for a while! I'm almost going to walk from one end to the other!" replied the Celestial King Masked Man, "You should be glad that the experimenters here are resting, and if there are still people here, you won't be able to get out so easily!"

"Oh, I know, let's get out of this lab! I'm going to rebuild the light soon!" Shen Zifeng said as he walked.

"Let me tell you a fact! You are still in Lu Yu's underground base, and the laboratory only occupies a small part of the entire base, so it's too early to get out?"

"What?" Hearing this fact, Shen Zifeng was very surprised.

"So, the headquarters of their "feudal state" is underground?" The blonde man asked.

"Yes, if you want to find that guy Lu Yun, you still need to go down!" The Man in the Mask of the King answered his question.

"I want to go down!" Shen Zifeng suddenly made this request.

"Go down, this can't be done, there are a lot of masters guarding below, just a few of us will basically die if we go down!" The Celestial King Mask refused his request, "Thank God you can escape to the surface!"

Before the three of them left the lab, they were attracted by a foul smell.

"It smells so bad!" Shen Zifeng complained.

"Looks like it's coming from that corner!" The blonde man gestured to a corner not far from them.

"Is it there? I can't see it very clearly!" Shen Zifeng said.

"Let's go check it out!"

The three of them came to a corner of the laboratory, where the gore was no different from that of a slaughterhouse. The smell of blood made the trio have to cover their noses.

I saw that there were all kinds of animal corpses on these experimental tables, including human corpses, and even more terrifying, there were still wreckage on the experimental tables, and the experimental tables and the ground were full of animal blood.

"It's so inhuman!" Shen Zifeng said and immediately covered his nose with his hand.

"Don't look at it, look at it again, don't miss the best time to escape!" The Celestial King Masked Man urged from the side, "If you can't escape from this place, you will end up like these animals!"

"Okay!" Shen Zifeng agreed, and walked out of the laboratory with the other two, this bloody scene Shen Zifeng could never forget.

The danger had only just begun from the moment they left the lab, and countless pairs of eyes were staring at the two of them.
