In this secret realm, the treasure elixir and the fierce beast are generally born and accompanied.

To obtain natural materials and earth treasures, we must first face the challenge of fierce beasts.

And there are also some fierce beasts that are precious drugs themselves. For example, this thunder cow is covered with treasure.

The shell on Lei Niu's back is the best material for making protective gear. Lei Niu's body has excellent conductivity. Blood is the best choice for writing holy stripe. The shell of the body is also the best material for making soft armor and special holy talisman.

But leiniu is also extremely dangerous.

Although they are like snails in the mundane world, slow in action and slow in response, the reason why they can grow to such a huge body is that they control the power of lightning as their name suggests.

At ordinary times, you can shrink in this hard shell that is too hard for the enemy to start. When you want to attack the enemy, as long as you stretch out two tentacles, you can emit extremely strong lightning. It is said that if you can survive the thunder and lightning of Lei Niu, it has a miraculous effect on external skill forging.

Such a big thunder cow is a windfall.

The little eagle was smiling and was about to start.

Gu Yuan suddenly gestured and asked him to look forward.

Let's look at the Bush "hill" in front of us.

Soon we found something wrong. In the so-called hills, some stones were trembling slightly, as if they could breathe.

What happened?

Can the stone move?

Of course, real stones can't move. Take a closer look, these brown yellow giant lying stones of different sizes are clearly a thunder cow lying on the ground sleeping

This discovery startled the little Eagle who almost acted rashly.

If it was a lone thunder cow, they would not let it go, but there were countless thunder cows lying in this "hilly" shrub land for miles

As the saying goes, it will affect the whole body at once. If the little Eagle rashly started just now, he may have been besieged by these thunder cows now.

"No wonder there is no living thing in this area..."

The little Eagle couldn't help muttering to himself. As a once arrogant genius, at this moment, he couldn't help being a little distracted.

Gu Yuan was calm.

Because he clearly felt that the thunder cow's heartbeat at his feet was very slow. It seemed that there was no emotional fluctuation because of their existence.

Whether the thunder cow is asleep or awake, it doesn't seem to care that several tiny "creatures" step on his back.

"We first slowly get down from this thunder cow, and then quickly exit this thunder cow land and continue to move forward in other directions."

Through the simple map, they had a general understanding of the habits of Lei Niu.

Lei Niu likes to burrow into loose humus to inhabit and lay eggs. If it can be so quiet and motionless in groups, it can only lay eggs.

This is the first time that we have encountered such a large-scale spawning.

The little Eagle asked puzzled, "why do you say these thunder cows spawn collectively?"

Li Cheng patiently explained, "in addition to leiniu, as far as I know, many fish and turtles also lay eggs collectively. I heard that some turtles lay eggs on the beach. Every time it's spawning season, the whole beach is full of turtle eggs.

This spawning time may last for several days, so as long as we move faster and leave, it's still safe. "

Fierce beasts also retain their own animal nature. Any creature has maternal nature, and reproduction is a necessary condition for the survival of the population. Therefore, these small "creatures" that disturb their spawning will ignore them and concentrate on spawning as long as they have not been harmed.

However, if they wait for their eggs to finish, these creatures will leave without interest. In order to ensure the safety of their eggs, they may have to let alien species die on the spot every minute.

"However, the number of these thunder cows is too much?"

"Leiniu is a nocturnal animal.

They like humidity and are afraid of drought, and in this secret environment, they don't have many natural enemies, so they can reproduce such a huge number. "

"Besides, how do you know they are laying eggs?"

"We all copied a map of Zhan Beibei, which is introduced in detail. Who makes you lazy?"

"I see when you copy.

I have to draw and write by hand. It takes a long time to toss, and I don't want to do it. Besides, aren't you the same as me? "

"Zhan Beibei's introduction about Lei Niu is very detailed. Lei Niu usually hides in the soil. Only when laying eggs, half of them are exposed and half of them are buried in the soil."

"That's what you see now, so when they lay eggs collectively, that is, when they are weakest, every time when they lay eggs, their enemies will come to beat the autumn wind."

"We can talk about leiniu after we leave. What we need to do now is to leave here as quickly as possible and retreat to a safe place. Everyone should be careful and don't disturb them."

Gu Yuan's words seemed to be an inevitable omen. They had not completely quit the land of thunder cattle. Suddenly, a short, sharp sound of explosion came from the far horizon.

"Buzzing, buzzing..."

"Buzzing, buzzing..."

The sound is very harsh, like someone pulling the glass with foam.

This is the effect that the sound generated when the wings of insects rub against each other is amplified countless times.

This sound is like a talisman for Lei Niu.

Everyone soon felt the vibration of the land. After this burst of explosion, it seemed that all thunder cows vibrated at the same time.

After this shock, the heartbeat, which was still relatively regular, began to accelerate.

This acceleration is not only the vibration that can be felt when the sole of the foot touches the shell.

It seems that the whole earth, even the surrounding air, began to vibrate at the same frequency.

The earth was buzzing with shock. In the bushes, the only remaining branches and leaves of the huge fruit eaten by thunder cows rustled, as if they were going to completely polish each other's branches and leaves, and some small stones couldn't help bouncing and fluctuating on the ground.

Gu Yuan glanced at the horizon in the distance. It seemed that there were dark clouds on the top, and the mountain rain was about to come. He immediately thought of something. He quickly stretched out his hand to hold the little eagle, called Li Cheng and Yun Duoduo, and no longer did any disguise, nor did he care whether Lei Niu would find himself and rush out of the land of Lei Niu.

They escaped quickly.

But the stars fell faster, accompanied by bursts of buzzing in the sky, hundreds of thousands of huge fireballs like stars were hitting here quickly.
