Lin Feng followed Mo Yan as they went deeper, the cave was dark for him, but he could still see some distance. But as they went deeper, it became even darker.

Mo Yan could see clearly in the dark too, not to mention she also had spiritual sense, but she knew that Lin Feng wouldn't be able to do so, that's why she had brought a light talisman with her.

She took out one and activated it, the talisman began floating above their heads and stayed there as she controlled it with her spiritual sense.

Lin Feng was finally able to see clearly, he was surprised because the cave had widened a lot, and right now they were standing in front of a big hole.

"This is the real entrance of the mine, junior brother, once we reach the bottom, we will be in the mine," Mo Yan said and extended her arms toward him.

He took it as he couldn't fly, but instead of being carried like an object, he pulled her into his arms and hugged her tightly, her bosom got flattened on his chest.

Mo Yan just shook her head and wrapped her arms around him while flying inside the hole. She really couldn't believe her own thoughts, as she felt it wasn't even a big deal... didn't it mean that junior brother was speaking the truth that after this mission she would change completely?

After two minutes, they left the hole and came into a vast expanse, Lin Feng got a little stunned, it was a massive cavern. There was no need for a light talisman either, as there were spirit crystals present inside the cave, spirit crystals are a little different from spirit stones.

Unlike spirit stones, which contain spirit qi they absorb, spirit crystals didn't absorb spirit qi, instead they used that spirit qi to produce light, and there were a lot of them here.

So much that it was as bright as day inside this cave, he could see a lot of spirit herbs scattered inside the whole cave and its walls, there must be a lot of rare spirit herbs here too.

Lin Feng was really awed by this cave, given its size, their sect had found a treasure trove, not to mention it was only an entrance, he could see that it went far deeper inside the mountain, probably covering a lot of mountains in this mountain range.

There was even an underground river going along the whole cave.

"We also found mystic obsidian and profound jade ore veins in this cave, this cave's value is really unimaginable, junior brother, if I have to say, then this mine is even more valuable than our other sources of resources combined," Mo Yan said with a smile.

Lin Feng nodded, even without the presence of anything else, this mine would be far more valuable than their other resources, because after entering here, he could clearly see that it was a very big mine, far bigger than what he had imagined before.

This mine definitely had more than one high-grade spirit stone vein. The abundant amount of spirit qi density, even after being absorbed by so many spirit herbs and spirit crystals, was proof of that.

Forget about those two sects, even the top sects of some big worlds would initiate a full-scale war for it.

"Let's go, junior brother, we have already found the cave that goes deeper where we can find high-grade spirit stones," Mo Yan said and flew toward a particular cave entrance inside this huge hollow space, there were a lot of these caves here.

They entered inside, and Lin Feng could already see a lot of lower-grade spirit stones on the entrance itself, this cave was not very big in height and width, it was about double his height and width, only two people could walk inside.

But looking at the amount of spirit stones poking out of the cave walls, no matter which direction they started mining, they would find a lot of spirit stones. After one minute, Mo Yan landed on the ground and unwrapped her arms around him, waiting for him to do the same.

Lin Feng smiled and hugged her tightly, while moving one of his hands down and grabbing her perky mounds while inserting his middle finger into the crevice where her rear hole was, and when he touched it, he felt her tremble a little, "Tonight, I'll breed this hole of yours, Senior Sister." His voice was filled with raw hunger, he was still not satisfied from their earlier intimacy.

Mo Yan quivered just thinking about it, she knew it would happen, so she wasn't surprised, but just thinking how that monstrous cock would even enter it was making her tremble a little, she couldn't believe how her master and aunt were able to take it in...

Lin Feng finally let her go and looked around, it was the end of this cave, he could see a few high-grade spirit stones in front where the cave ended, so no doubt if they mined here, then they would get some high-grade spirit stones, and as they moved deeper, it would increase in quantity.

But they had to dig the cave.

"Senior sister, you can sense the main spirit veins, right?"

"Yes, of course, junior brother, it is going above us, about three meters deep. So even if we mined in the front direction, it won't affect it," Mo Yan nodded.

Main spirit veins are branches that are directly connected to the spirit stone vein, and these veins consist of multiple small branches that later form spirit stones.

Destroying small branches while mining is normal, they will recover in a few years, probably a decade, and they will start producing spirit stones again.

But it is different for main branches, if they are destroyed, then it will take probably a hundred years for them to repair, so it is very necessary to not destroy them.

Lin Feng nodded, "So we are going to just mine now?"

"That's our main mission, but I also have to draw a teleportation array here."

"Senior sister, draw that array later," Lin Feng spoke hurriedly. He didn't want anyone else coming here and destroying their alone time together.

Mo Yan understood why he said it, "Junior brother, don't worry, no one will come even if I complete it, the other part of this array is on Mission Peak inside Peak Master Hua Ying's abode."
