Then, he waved to Han Sanqian, got up and walked towards his stove.

Han Sanqian and the other two quickly followed, and then the group of four arrived next to the stove.

Next to the stove, there is a small wooden cabinet. The old man is about half a tall body and is covered with dust on his face. In addition, it is placed in the corner. If you don’t look closely, it will be difficult for ordinary people to notice.

You said it was a mound of soil, and no one seemed to doubt it.

He gently patted off the dust on it, and half of the room was filled with dust for a while. Then, with the sound of creaking wood, he opened the cabinet.

When the cabinet was opened, about half a box of dry green plants lay peacefully inside.

"If you want to move the treasure pot, you still need this. This is a special thing in the extreme snow. Although it looks like grass, it is actually not grass."

"What is this?" asked the pangolin.

The old man smiled gently, took out a dried green plant, then gently put it in his hand to crush it, lifted his hand and put it in front of the three of them.

This thing is very broken, like powder.

"Miba??"

"sand?"

Pangolin and Xia Wei guessed.

"It's a fish egg, right?" Han Sanqian asked.

"Fish egg?"

When he heard this, Xia Wei and the Pangolin made a sound in surprise almost at the same time, and opened their eyes wide to look at the powder in the old man's hand.

It is as thin as sand, with extremely small particles. It is extremely difficult to say a word about sand, let alone involve it with fish and eggs.

The moonlight ghost fish is so big, how could the fish eggs be so small? And even if it is a very small fish species, the eggs it grows are definitely not as funny as that.

"You're right."

But at this moment, the old man looked at Han Sanqian and nodded with a smile, which was considered to be acknowledging Han Sanqian's statement.

The two of them were shocked and exclaimed: "Is this really a fish egg?"

The old man nodded, and Xia Wei and Pangolin suddenly looked at Han Sanqian strangely. He really didn't understand how Han Sanqian connected these things to Yudan.

Han Sanqian smiled. Obviously, this was indeed a guess, but it was also a well-founded guess.

The old man once said that there are only two types of creatures in this extreme snow land, one is the blood worm and the other is the moonlight ghost ray. The extra plants are already suspicious.

Secondly, if a place is closed, it is like this extremely snowy place. If it lasts for a long time, it will inevitably have its corresponding ecosystem.

This is the key to the formation of an area.

"If I guessed correctly, these fish and eggs are also food for those bloodworms, right?" Han Sanqian said.

The old man smiled and nodded again: "Young Master Han is smart, that's true."

Han Sanqian smiled and said, "That's right."

Moonlight ghost fish are mainly fed by bloodworms, so old men can use bloodworms to catch moonlight ghost fish.

But how can the bloodworm survive? In this extremely snowy place, there is only the only creature, the moonlight ghost ray.

This reminded Han Sanqian of the Snake Island on Earth.

Almost everything in the snake island is full of snakes, and almost everything except snakes cannot be born. There are only simple seabirds that occasionally skip the island to stop temporarily, but this does not allow the gradually expanding snake group to have enough food.

However, snakes can still survive and expand because there is another creature on the island, that is, mice.

The natural enemy of mice is snakes, and naturally they are also the food of snakes, providing essential energy for the growth of snake groups.

However, despite this, the mice on the island have not become extinct because of this, and even the number continues to expand gradually.

The reason is that although snakes feed on rats, mice will use snakes as food when they hibernate. The two rely on this to form an ecological chain to make the island prosperous.

Isn’t this extremely snowy land like the snake island?

The blood worm was eaten by the moonlight ghost fish, but the blood worm clan was still growing. This shows that the blood worm must also feed on the moonlight ghost fish.

Big ones are not good, small ones are OK, right?

This is Han Sanqian's guess that these are fish eggs and bloodworm food.

"I even understand one thing." Han Sanqian suddenly looked up at the old man.

Xia Wei and the pangolin were like two confused rattles, looking at the old man as Han Sanqian looked at the old man, and at the same time, he turned Ben to the old man's eyes.

The old man smiled slightly: "Oh? What's the matter?"
