After emptying the tree hole, Li Yiyi said goodbye to Lin Zhuosheng and Luo Meiren, and then walked towards the city gate with the two worms, and when she was waiting for inspection at the gate, Li Yiyi heard someone calling her, and turned her head to see that it was Qin Bai.

"This is for you, I know you are a stranger, this, you only need to inject power into it to use, this thing is very precious, you must put it away."

When Qin Bai saw Li Yiyi, he quickly stuffed things into her hand and instructed in a low voice.

Li Yi looked at the bamboo tube in his hand, and his dark eyes skipped a smile slightly.

"I don't even know what it is, and how do you know I'm a supernatural."

Qin Bai saw that the line for inspection was quite long, so he said:

"Now I can still sell grain and wine, and the only thing I know is wood."

Li Yiyi suddenly realized, but I really hope it is wood, but unfortunately I am not.

"I don't take people's things for nothing, this is for you, it's an exchange between the two of us."

As he spoke, Li Yiyi took down a five-colored stone from the nouveau riche gold necklace and threw it to Qin Bai.

Qin Bai looked at the five-colored stone in his hand and asked Li Yiyi

"What is this?"

"Burying it in the soil can turn two acres of land into fertile soil suitable for planting."

There weren't many words, but it was enough for Qin Bai to be shocked, and he could plant!! In the last days, in this ice age, where there was almost no grass, some people even said that this thing could make the frozen soil grow food! This woman is too bold, and she dares to give away this kind of treasure at will!

"No, this is too precious, I don't want it, you take it well."

Li Yiyi tilted his head one by one, how could this person still pick it, he didn't want the five-color stone, so ......

"Since you don't want this, then I'll give you this."

Today, this causal old lady has to go back!

Taking back the five-colored stone, Li Yiyi took out another piece of lilac crystal nucleus and stuffed it into Qin Bai's hand.

Qin Bai's eyelids jumped, and he felt that he might have been rejected.

"What is this?"

Li was annoyed by the question

"You have so many questions, the courtesies are still exchanged, if you give me something, then I have to return the gift, this is the rule, understand?!"

“…… Oh. ”

Qin Baiyi's 'post-apocalypse' really no one has taught him this.

Just as he was stunned, Li Yiyi had already passed the checkpoint and walked into the distance.

When Qin Bai came back to his senses, he happened to see that Li Yiyi had already walked out of the city.

"Alas......"

With a faint sigh, Qin Bai walked back a little depressed, and when he got home, Qin Bai found that the crystal nucleus was still in his hands.

Spreading out his palm, Qin Bai knew that this was a low-level crystal nucleus, which was of little help to the current people, but he was still curious to input power.

The lilac crystal nucleus emitted light, and Qin Bai also screamed in an instant

"It's !!"

Tonight is a full moon, and it is very large, and from time to time there are a few clouds floating in front of the big moon like turtles.

At this moment, a figure suddenly burst out of the clouds, the figure hovered in the air, turned its head to look in the direction, and then disappeared in a flash.

Two days later, Li Yiyi hovered in the air and looked at the black snake-like sinuous crack in the white snow below.

Looking at this crack, Li Yiyi suddenly remembered the North Third District a few decades ago, when there was such a long trench not far from the outer city gate, but it was dug manually, and one was natural at first glance.

"Here's ...... Is it volcanic lava or an underground hot spring, making such a big fog? ”

Li Yiyi rubbed his chin one by one, do you want to go down and take a look, the hot steam fumigation from below is so comfortable, but it's so dark here, what if a super boss suddenly pops out! She's scared!

"Humility, hehehehe."

After following Li Yiyi for so long, how could he not know the urine of his boss, so he didn't even bother to say anything, and flew out of Li Yiyi's arms directly, and jumped into the bottomless crack.

Li Yiyi and the big earthworm waited on the edge of the crack in the ground for more than an hour before humbly coming out of the crack in the ground.

waited for the humble heart to return to Li Yiyi's arms before saying:

"Boss, it's very deep down there, almost more than 2,000 meters, there is a river at the bottom, the river is very hot, I explored the water, and within my perception range, I didn't find any creatures."

"Well done."

Li Yiyi rewarded Humility with a high-grade earth attribute spirit stone.

Humbly satisfied, he put the spirit stone into the storage bag, and then squeezed together with the big earthworm to sleep, and when he went out, it was almost freezing.

If it's okay, what are you waiting for?

"Whew!"

Facing the wind and snow, Li Yiyi learned the diving athlete's falling action and jumped into the dark ground crack, which was very wide, so Li Yiyi simply let go of himself and began to fall freely.

When the descent reaches about 500 meters, the spacing between the ground cracks gradually narrows, and then it is changed to fall against the wind.

The deeper he fell, the higher the temperature, and when Li Yiyi landed on a protruding stone platform above the boiling river, the temperature and humidity around him were estimated to be comparable to those of the previous sauna.

Li Yiyi shook his head and said after probing around:

"This place won't be the back door opened by God again."

The temperature of this underground river is about 120 degrees, and with her divine sense, she can't even reach the bottom of it, and there are no living creatures under the water.

But these are not the most critical, the most important thing is that this water can be drunk!

Li Yiyi has a beast-shaped jade pendant that can be tested for toxicity, if it is poisonous, the jade pendant will turn purple-black, and if it is not poisonous, it will not change.

Because there are hot springs on her Sun Moon Mountain, the hot springs there have a strong smell of sulfur, but there is no smell in this hot river, in order to confirm the guess in his heart, Li Yiyi took out the jade pendant.

"Damn, this is a bug in the apocalyptic Ice Age."

Such a good place, don't take it for yourself, I'm sorry for myself!

If there is an underground river, then there should be no possibility of a sudden merger in this crack, and in addition to this worry, she must now find the source of the river.

Even if you can't eat the whole seam, at least you have to hold the source in your hands to feel at ease.

Li Yiyi looked in the direction of the countercurrent, and then set a ban here, in case other people or demon beasts broke in while she was away.

After going upriver for about half a day, Li Yiyi finally saw the end of the crack.

"Nima, this slit is too long, and it almost kills people."

Landing on a stone platform, Li Yiyi simply sat down and rested first.

Looking at the huge dark red cavern in front of him, where the boiling river was constantly pouring down, Li Yiyi couldn't help but sigh again at the creation ability of nature.

After resting enough, Li Yiyi flew out of the crack in the ground and found that the source of the crack turned out to be a super snow mountain!

"Shall I take this mountain together......

The greedy Li has now attracted the attention of this snow-capped mountain again.
