Zi Yao pulled out the metal wire and stood in front of the stainless steel door with Lord Evil Monarch waiting for the door to open, and with the sound of "creaking", the door slowly rose inward, and a completely different scene from the end of the world was displayed in front of the two.

The evil monarch was also extremely shocked, and took Zi Yao's hand and walked inside, the warm spring wind was blowing slowly, and the soft lights in the vast space were evenly distributed on the roof of the cave to illuminate the entire space, and all kinds of green vegetation appeared in front of the eyes.

The position on which they stood was the commanding height of this huge space, from which two gentle roads led downward, and the whole space was extremely rich in vegetation, including apple, pear, cherry, papaya, walnut, camphor, wheat, corn, cucumber, eggplant, potato, and so on.

The stainless steel door behind them may have been set up with a timed automatic closing function, and a 'creaking' sound closed again, Zi Yao and the Evil Monarch were not worried because now the two of them used stealth techniques, unless they used infrared detection equipment to find their traces.

The evil monarch took Zi Yao's hand and the two jumped up along the middle road, and quickly jumped towards the end of the road, Zi Yao had no time to complain, it was already half an hour later when the two crossed the edge of this cave, Zi Yao roughly calculated, this is an area of more than 70 square kilometers.

On the way over, they saw a lot of people working, these people were a little strange, for some reason they seemed to be machines, their movements were very stiff, and no one talked or laughed, all of them bowed their heads and worked seriously, and the frequency and speed were the same, which made Zi Yao extremely puzzled.

Of course, the evil monarch felt Zi Yao's doubts, and Miyin told Zi Yao, "These people should also be a form of zombies, maybe one of Kong Xunxian's experimental varieties!"

Zi Yao suddenly realized, grabbed a person's wrist nearby, and probed his body without interrupting his work, as the evil lord guessed, this person is also a zombie, but he can't evolve without a crystal nucleus, but he can complete the instructions and arrangements of high-level zombies to work.

What a cheap and obedient labor force this is! I don't know how to betray yet, it seems that this Kong Xunxian's research on the zombie virus has reached a certain height, Zi Yao is no longer entangled and turns around and pulls the sleeve of the evil monarch, and the two of them walk towards a low passageway.

Beyond the passage, a wider space appeared in front of Zi Yao and the Evil Monarch again, this place was wider than the cave just now, the height of the cave had exceeded two hundred meters, and a sun was modeled in the middle with a set of lights.

In the place where Zi Yao and the others are standing, there is a crack in the wall of the cave on the left hand side that is gushing with spring water, bubbling spring water, forming a pool of water below, along the terrain of the cave constantly stretching to the right side, forming an underground river, the surrounding green crops are more abundant, many are not the species that Zi Yao and the Evil Lord know, there is no shortage of traditional Chinese medicine and some rare plant species.

Some of the traces on the high cave cliffs are artificially carved and some are naturally formed, Zi Yao analyzed that this place should have been a place for soldiers in ancient times, but it was expanded and renovated by Kong Xun first, and then planted a large number of vegetation and crops, this is no longer Noah's Ark in the general sense, this is an underground royal city.

Following the direction of the water, the two of them walked cautiously, Zi Yao had already explored that the water here had not been polluted, she was extremely puzzled, why all the rivers on the ground had basically dried up except for the seawater, but the water here had not been polluted and dried up?

Could it be that like Enron, they built their own water treatment plants?

Thinking about a patrol team coming over, although the two of them were invisible, they couldn't directly block the right road, so they quickly jumped up and fell to a ginkgo tree on the edge of the underground river, and the team members who passed below kept complaining.

"Patriarch Kong won't let that kid named Liu Qixuan stay!" A thin little boy asked suspiciously.

"Cut! Stay, why stay? I don't know if he really has the ability, although he has a lot of people, but if he wants to join the temple, he must have a certain strength, it depends on the price he can't come up with!"

"No, the surname Liu really has this strength?"

"Why do you defect to us when you have this strength?"

"Stupid, I guess I offended someone! I want to find the protection of Patriarch Kong! I can't understand this?"

“……”

A few people walked farther and farther away as they spoke, Zi Yao and Lord Evil Monarch jumped down, and Zi Yao asked in confusion, "Why did Liu Qixuan go here? How did he know that there was such a base?"

The evil monarch rubbed his chin with his index finger, pondered for a moment and replied seriously: "Demon, he should have known some secrets of the end times through Enron's spatial ring, otherwise he would not have been able to find it so directly, and he would have brought all his personnel over!"

Zi Yao suddenly realized, "By the way, An Ran once wrote all his memories into a notebook and put the notebook in the space ring, if Liu Qixuan finds this notebook, he will understand everything, I see! A scumbag is a scumbag, and he thinks of himself in everything!"

What the evil lord is most happy to see is that the demon only has his own appearance in his eyes, and what male protagonist and female protagonist all retreat!

Holding Zi Yao's hand and walking while discussing, Lord Evil Monarch felt that this space was only Kong Xunxian's planting space, and his experiment and living area should not be here, and sure enough, the two of them checked around and found no useful value, and the most in the space were zombie laborers.

Zi Yao and the Evil Monarch followed the road to find another passage, and there were people guarding here, the Evil Monarch and Zi Yao held hands and looked at each other, they were not afraid of these people, but they disturbed everyone and were not conducive to the next step of the investigation, and after thinking about it, Zi Yao secretly told the Evil Monarch.

[After a while, when someone comes out, you use a little wind spell to blow up some fine dust like this, and while everyone closes their eyes, we dodge in, how about it?]

The Evil Lord nodded, and the two of them stood next to the guards and waited quietly, and after a while, the patrolling people had just returned, and the two followed these personnel closely and blended into the passage.

As soon as you enter here, you will feel that you have entered a small town, with five-story stone caves on the right hand side and left hand side, with windows and doors, as well as platforms and stairs to communicate with the bottom, at a glance it is an ordinary person's house, and roughly counted that all the stone houses are not less than 20,000 or 30,000 rooms.
