Lan Xi waited in place for about ten minutes before he saw a small shadow flying up from the depths of the crypt.

"Master, I've already found out everything about this place." Mobao flew back to Lan Xi's side and said.

"Tell me about it." Lan Xi leaned against the wall, playing with the dagger in his hand.

"I have made preliminary calculations that the city should be able to accommodate 50,000 to 80,000 people, and in addition to these residents who live on the rock wall, there are many residents on the ground floor. However, those who live on the ground floor should have a lot of status in this place, and each of them is equipped with a vehicle that can fly, and the size of the house is much larger. And I also found that the inhabitants of this underground city are most likely not human. Mobao said.

"Not human?" Lan Xi was slightly stunned.

"Hmm." Mo Bao nodded, "On the way to find the teleportation array, I saw a lot of stone sculptures, although these stone sculptures look very similar to humans from a distance, but up close, they are all creatures with lizard heads and tails. If I'm not mistaken, this is supposed to be a lizardmen's lair, and the environment here is also suitable for the lizardmen's living conditions. ”

"Lizardmen?" Blue Creek was a little surprised.

Lizardmen are a relatively common race in the universe.

They have a lot of strength, but they can't cultivate.

So I can only be enslaved by humans to do some drudgery that requires effort.

"As for the teleportation array, I also found it, but the damage is very serious, from the surface, it should be an ultra-long-distance teleportation array, and every time it is activated, it needs to consume no less than ten high-grade spirit stones." Mobao continued.

"Since this place can be used as a temporary residence for the lizardmen, it means that there must be something they need here." Lan Xi raised his eyes and glanced at Mo Bao, "Have you searched those buildings on the ground floor?" ”

"We've searched it, but we haven't found anything of value." After a pause, Mo Bao continued: "Since the people of Moyun Mountain know about the teleportation array, then they must have been to the bottom floor, and it is very likely that the useful things in those buildings have been looted by them. ”

"I have a guess." Lan Xi narrowed his eyes.

Here, since there are a large number of gold-swallowing rats, it means that there are a lot of metals in this place.

Plus she had seen interest money before.

It was a rare metal that was used to make high-tier warships and ships.

It is also very powerful when used to refine weapons.

However, after all, it is not a material for refining weapons, and there is still a certain gap between it and advanced magic weapons.

"Mobao, check the geology here." Lan Xi suddenly spoke.

"Yes, master." Mobao nodded obediently and turned on the scanning function.

After about a few minutes, Mobao had a result.

"Master, I found a vein of gold ore, this vein is about two thousand meters underground, and the degree of mining is less than twenty percent." Mobao opened the virtual panel, and then placed the scanned vein structure map in front of Lan Xi.

"Sure enough." Lan Xi was not too surprised to hear this result.

The only thing that made her puzzled was that such a large vein of interest gold, less than 20% of the mining level, all the lizardmen here were transferred.

Was there some accident?

Lan Xi set her eyes on the structural diagram of the ore vein, and soon, she made a discovery.

"What is here?" Lan Xi asked, pointing to an area on the tectonic map.
