From seeing it

No one expected that at the end of this giant rock passage, a huge abyss appeared again. At the bottom of the abyss, there grew an undead tree, which grew all the way from the bottom of the abyss to the top of the cliff.

Looking at the countless colorful undead mushrooms growing from the undead tree, this scene is so familiar, these are almost two identical undead trees.

Seeing an undead tree again, everyone was inexplicably surprised.

This undead tree is an ancient and strange tree. It is even said that it existed when the earth was formed, and it has taken trillions of years to grow to a height of a kilometer.

It is unimaginable that such an ancient and strange tree exists. No one would have imagined that there is a second immortal tree in this underground world.

Behind the giant rock passage, there was a faint rumbling sound, and the ground was shaking slightly.

"No, the magma eruption is getting more and more violent, and the magma will soon spread over." Hu Shengzhe's face changed color, and he turned to look at the dark passage behind him.

The eruption of underground magma this time was really frightening, and the passage made of stone gates and solid rocks was unstoppable. Everyone rushed all the way, but after all, they couldn't escape the natural power of the magma eruption.

Everyone felt the ground shaking, and the shaking became more and more intense. In the rock passage behind, a crimson light suddenly lit up in the darkness.

Soon the rays of light became fiery red, like a blazing sun rising up.

The magma was flowing and impacting along the rock passage, and appeared within a hundred meters of the passage behind everyone.

There is no retreat, the huge canopy of the undead tree is ahead, and the dark abyss is below, no one knows how deep this abyss is.

Having no choice, Xiao Ling suddenly let out a low voice: "Let's go!"

He made a decisive decision and was the first to rush to the oncoming canopy. As before, the only choice for everyone was to use the layers of canopy formed by countless undead branches to escape to the bottom of the deeper abyss below.

At this moment, everyone is already three thousand meters below the ground.

Zhou Kesheng, Yu Tingting, Wang Lei and others rushed up to the canopy of the tree. The temperature in the air was gradually rising. There was a hot airflow impacting the rock passage, and the turbulent magma flowed along the rock passage.

Eight people stepped on the crown of the tree, and with the help of densely packed thick branches, they descended at full speed.

Soon there was a bang from above, and suddenly a burst of fire tore through the darkness above. Xiao Ling raised his head and saw fiery red magma spraying out along the exit of the rock passage like a fountain, pouring down, All sprayed on the crown of the undead tree.

All kinds of piercing sounds sounded, and a large number of branches were breaking off, followed by a "blazing" sound, but it was the large group of branches that burned violently.

The fiery red magma was constantly spraying, pouring down along the crown of the tree, and a large number of branches and colorful mushrooms were burned, burning flames, and the scene was appalling.

Everyone had fled to the other side of the canopy tens of meters away, and then continued to flee downwards, and soon reached a hundred meters below the canopy of the undead tree.

Fortunately, the first round of magma eruption was not powerful enough to completely engulf the huge undead tree.

A large amount of magma flows down, reflecting the darkness. At this moment, there is no need to use searchlights and camping lights. Under the magma and the burning undead tree flames, the surrounding area can be clearly illuminated.

This is an underground abyss with a diameter of hundreds of meters and a depth of a thousand meters. In the center is an ancient strange undead tree. Layers of tree crowns, from top to bottom, become a passage that can help everyone climb up and down.

In the rock passage above, a large amount of magma sprayed out along the passage, igniting the branches of the undead tree. The temperature in the abyss was rising, and everyone felt hot and sweaty.

Between life and death, everyone fled desperately, kept going down, and soon followed the undead tree to a depth of two to three hundred meters. Eight people climbed to the other side of the undead tree, avoiding the direction of the magma spray, but The flame ignited by the magma burned more and more vigorously, and gradually approached downwards. The entire abyss was illuminated by the flames, and the eternal darkness of thousands of years was swallowed at this moment.

Xiao Ling was the fastest, and there was still darkness below. This undead tree was no smaller than the one he encountered before. Based on this calculation, the abyss was probably a thousand meters deep. When everyone reached the bottom of the abyss, it was equivalent to falling It reached the area below 4,000 meters underground.

But Xiao Ling knew that this depth was nothing compared to the earth's crust.

The thickness of the earth's crust is uneven, with an average thickness of about 17,000 meters. The average thickness of the continental part has reached an astonishing 33,000 meters, and the thickness of some high mountain areas can even reach 60,000 to 70,000 meters.

The 4,000 meters underground is still on the surface of the earth's crust.

Xiao Ling was the fastest, followed by Liu Guangsheng, Qin Yang and Zhou Kesheng. Although Zhou Kesheng was not young, his agility was not inferior to young people.

As the flames from above gradually approached downwards, the temperature became higher and higher. In the flames, a large amount of magma erupted from time to time, making the situation dangerous.

Suddenly, a scream sounded beside Xiao Ling.

Xiao Ling, who was going down with hands and feet, was shocked, and hurriedly turned his head, and saw Du Changde on the other side of the team suddenly fell down, and there was an extra person at the position he had just climbed, grinning , smiled.

This person appeared silently and suddenly, no one noticed beforehand, and when Du Changde reacted, he had already snatched the military waist knife from his hand, stabbed it into Du Changde's chest, and kicked him off.

Du Changde fell down with a shrill scream, smashing several branches of trees all the way down, rolling along the canopy to the edge, and disappeared into the darkness below in an instant.

"Zhang Shuang——" Xiao Ling's eyes suddenly widened with a terrifying light, and he couldn't help shouting.

This suddenly appeared in the canopy of the tree, and the person who grabbed the knife and killed him was Zhang Shuang, an instrument expert who should have died long ago.

At that time, when everyone saw the first immortal tree, a group of people went down the tree. As a result, Zhang Shuang was attacked by the man-eating beast. One face was bitten off, and he fell to his death. Even the bones were not found.

No one would have thought that Zhang Shuang, whose face had been bitten off and was already killed, suddenly reappeared in the canopy of this undead tree like a ghost, and even snatched the military waist knife from Du Changde's hand, and stabbed Du Changde with one blow. Chest heart, kicked it down.

Just like Xiao Ling, everyone was horrified by this turn of events. Zhang Shuang was as agile as an ape. After killing Du Changde, his figure flickered, and he wanted to pounce on Yu Tingting, who was only two meters away from him.
