There are not only plants in the underground world, but also many animals.

Rosa lightly covered her red lips, "It's incredible. There is such a vast underground world beneath the Desert of Death."

Yan Qingqing said calmly: "There are all kinds of wonders in the world. The Tianyuan Continent is vast and has countless secret realms. Who can say for sure what strange phenomena we will encounter?"

Her family background is mysterious and she has seen many secret places.

Although the underground world is mysterious, it is not enough to arouse her curiosity.

Not long after, everyone was blocked by a big river.

The temperature near the river dropped sharply, almost like entering an extremely cold ice cave.

Yu Yi frowned, "Stop first, there is something wrong with this river."

In fact, without his reminding, everyone understood that there was something strange about the river in front of them.

How can an ordinary river be so cold?

Yu Yi picked up a dead branch on the ground, walked carefully to the river bank, and touched the dead branch to the river water.

The end of the dead branch that touches the water quickly freezes and spreads upward along the dead branch.

He was so frightened that he hurriedly threw away the dead branches in his hands and retreated quickly.

"Damn it, how can I cross this river?"

Rosa frowned, "Can you fly there?"

Yu Yi shook his head and said: "I don't know, let's try catching a bird first."

Without Yan Qingqing's orders, several guards with bright minds had already spread out to look for flying animals in the underground world.

Not long after, a guard came back carrying a colorful strange bird.

He walked to the river bank and threw the strange bird into the air.

The strange bird got free and immediately flapped its wings to escape, but it couldn't fly and fell directly into the river.

As soon as the strange bird's body touched the surface of the river, its entire body was frozen into ice and sank into the water.

The river suddenly rolled violently, and a group of strange fish about one meter in size with small lanterns hanging on their heads and covered in red jumped out of the water, scrambling to snatch the strange bird.

The strange birds were eaten clean before they even sank into the water.

The strength of the lantern monster fish is not very strong, only around the first level, but there are many of them.

These strange fish have sharp teeth and are very difficult to mess with.

Yu Yi has no doubt that their teeth can bite through bones.

"hiss……"

Everyone took a breath of cold air.

Gu Boyuan couldn't help but swear, "Play with a hammer, the river is closed to air, the water is cool and there are countless red strange fish."

"What should we do?" Yan Qingqing was also a little confused.

The situation before us is beyond everyone's expectation. If you want to get out of the underground world, you must cross a river.

However, the river in front of us is not passable by ordinary people.

Even using ice spells to freeze the surface of the river didn't work. The temperature of the river water was already lower than the freezing temperature, but it didn't freeze due to some special reasons.

Rosa put away her charming expression and became unusually serious.

She looked at the strange river water and paced back and forth.

Yu Yi also held his chin with his hand, thinking about how to cross the river.

Yan Qingqing suggested: "I think we can cross the river on those strange fish."

Yu Yi shook his head, "I feel a bit confused. First, the strange fish is only about one meter in size. Can it bear our weight?"

Second, how to conquer the strange fish?

Third, when we step on a certain strange fish to cross the river, how can we ensure that we will not be attacked by other strange fish?"

Gu Boyuan smiled confidently, "Brother Yu's three questions are very simple: First of all, we are just borrowing strength. We only need to carve a formation under everyone's feet to reduce the weight, so we don't have to worry about the strange fish not being able to bear it.

Secondly, we can catch some animals and put them on the river bank, then attract the strange fish and blow them back to the bank.

As long as the strange fish reaches the shore, it is not at our mercy.

The third question is even simpler. Kill all the strange fish and leave only the number needed to cross the river. Then you don’t have to worry about being besieged by the strange fish."
