Back to the Age of Dinosaurs

In the distant forest lay some big dragons, including Diplodocus and Stegosaurus Ankylosaurus.

And Gulu found that these big dragons didn't have any wounds on their bodies, which proved that they were not killed by carnivorous dragons.

Taking a closer look, Gulu also saw that there were several ice spine dragons lying next to a diplodocus, and there was no wound on the ice spine dragon.

Gulu immediately realized that there might be some highly concentrated but colorless and odorless deadly gas in the forest.

Realizing this, Gulu immediately took Mungo back and had to go to an open place.

Gulu couldn't figure out what kind of gas it was, until Gulu saw that there seemed to be a few cracks on the huge ice wall next to the forest.

Glacier cracks will release a large amount of methane. Methane is colorless and odorless. If it is too dense in the air, it will poison people and of course dinosaurs. The forest is too dense, causing countless evacuations of methane gas.

A large amount of methane in the air is a precursor to melting glaciers!

Gulu ran very fast, and on the way back, he happened to meet a group of Parasaurolophus.

The parasaurolophus group rescued them, and Gulu immediately ran to Long and said, "Long, you follow Pado's group, don't go to other places, it is very dangerous now, you must follow Pado's group, come with me .”

Although Mungo was a tyrannosaur and was so close to them, these parasaurolophus were not afraid at all.

Because the IQ of Parasaurolophus is low, the leader thinks of Tyrannosaurus rex is scary, and they will be afraid if the leader sends them the information.

Now it belongs to the leader that he didn't think that the Tyrannosaurus rex was terrible. As long as Mungo didn't attack, they wouldn't be afraid.

Long looked blank: "Gulu, how do you know my name is Long?"

Gulu was shocked: "No, have you forgotten? The cave just before..."

Long slowly seemed to remember something.

In fact, Gulu can also understand that animals with low IQs generally have very bad memory, and the memory time is very short. They may only remember some very important things, or they may forget them at any time.

There is no time to say so much now, Gulu can only order him: "Long, you take the group and follow me now, immediately!"

At this time, Gulu saw Lauren and the group rushing towards them, looking very anxious.
