No one expected that at the end of this huge rock passage, a huge abyss appeared again, and at the bottom of the abyss, an immortal tree grew, and it grew all the way from the bottom of this abyss to the top of this cliff.

Looking at the countless multicolored undead mushrooms growing from the undead trees, this scene was so familiar, these were almost two identical undead trees.

Seeing an immortal tree again, everyone was surprised and inexplicable.

This immortal tree is an ancient strange tree, and even legend has it that it existed at the beginning of the formation of the earth, and it is unknown how many trillions of years it took to grow thousands of kilometers high.

The existence of such an ancient strange strain is unimaginable, and no one would have imagined that in this underground world, there is a second immortal tree.

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

"Oh no, the magma eruption is getting more and more violent, and this magma will soon ripple over." Hu Shengzhe's face changed color, and he looked back at the dark passage behind him.

This time the underground magma eruption was really terrifying, and the passage made of stone gates and solid rocks could not be stopped, and everyone rushed all the way over, but after all, they could not outrun the natural power of the magma eruption.

Everyone felt the earth tremble, and the shaking became more and more violent, and in the rocky passage behind them, a crimson light suddenly lit up in the darkness.

Soon the light turned a fiery red, like a blazing sun.

The lava was flowing down the rocky passage and crashing in, appearing within a hundred meters of the passage behind the group.

There was no way back, and in front of him was the huge canopy formed by the undead tree, and below was the dark abyss, and no one knew how deep this abyss was.

With no choice, Zhou Kesheng let out a low roar: "Go!" ”

The first one rushed to the oncoming canopy, and as before, the only option for everyone was to use the canopy formed by countless undead branches to descend and escape to the deeper bottom of the abyss below.

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

Xiao Ling, Yu Tingting, Wang Lei and others rushed to the canopy of the tree, the temperature in the air was gradually rising, and there was a scorching air flow in the rock channel, and the surging magma flowed along the rock channel.

Eight people stepped on the canopy, and with the help of dense thick branches, they went down at full speed.

Soon he heard a bang from above, and suddenly a firelight tore through the darkness above, Xiao Ling looked up and saw that the fiery red magma was like a fountain, spewing out along the exit of the rock passage, pouring down, and spraying all of it on the crown of the undead tree.

All kinds of shrill sounds sounded, a large number of branches were breaking, followed by a "raging" sound, but it was the large mass of branches that burned violently.

The fiery red magma was constantly spewing downwards from the canopy, and a large number of branches and multicolored mushrooms were burned, and the scene was terrifying.

Everyone had already fled to the other side of the canopy dozens of meters away, and then kept fleeing down, and soon reached a hundred meters below the canopy of the undead tree.

Fortunately, this first round of magma eruption was not very powerful, and it did not completely swallow and submerge this huge undead tree.

A large amount of magma flowed downwards to illuminate the darkness, and there was no need for the light of searchlights and camping lanterns to illuminate the surroundings clearly under the flames of the magma and the burning undead trees.

This is an underground abyss with a diameter of hundreds of meters, thousands of meters deep, with an ancient immortal tree growing in the center, the main body of the tree pole is more than 100 meters in diameter, and it is covered with luxuriant branches of different thicknesses in all directions, these branches form a canopy, from top to bottom, it becomes a passage that can help people climb up and down.

In the rocky passage above, a large amount of magma was spewed out along the passage, igniting the branches of the undead tree, and the temperature in the abyss was rising, and everyone felt the scorching heat and sweat.

Between life and death, everyone fled for their lives, kept going down, and soon followed the immortal tree down to a depth of two or three hundred meters, and the eight people all climbed to the other side of the immortal tree, avoiding the direction of the magma jet, but the flames ignited by the magma became more and more vigorous, and gradually approached downward, and the entire abyss was illuminated by the flames in a fiery red, and the thousand-year-old immortal darkness was swallowed up at this moment.

Xiao Ling was the fastest, looking at the darkness below, this immortal tree was no smaller than the one he encountered before, based on this estimate, this abyss was only a thousand meters deep, and when everyone reached the bottom of the abyss, it was equivalent to having descended to an area below four thousand meters underground.

However, Xiao Ling knew that this depth was nothing to the earth's crust.

The thickness of the earth's crust is uneven, with an average thickness of about 17,000 meters, and the average thickness of the continental part reaches an astonishing 33,000 meters, and the thickness of some alpine areas can even reach 60,000 or 70,000 meters.

The four thousand meters below the surface are 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 is not young, but his agility is not inferior to that of young people.

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

Suddenly, a miserable scream sounded beside Xiao Ling.

Xiao Ling, who was using his hands and feet together, was in his heart, and was busy turning around, and saw Du Changde on the other side of the team suddenly falling down, and at some point in the position he had just climbed, there was another person, who was grinning and showing a smile.

This person was silent, suddenly appeared, no one noticed it in advance, and when Du Changde reacted, he had already snatched the military waist knife in his hand, and stabbed it into Du Changde's chest with a knife, kicking him down.

Du Changde fell down with a terrible scream, smashing several branches all the way down, rolling down the crown to the edge, and instantly disappeared into the darkness below.

"Zhang Shuang?" Xiao Ling's eyes suddenly widened, and he couldn't help but cry out.

This suddenly appeared in the canopy, and the one who snatched the knife and killed was Zhang Shuang, an instrument and equipment expert who should have died a long time ago.

At that time, when everyone saw the first immortal tree, a group of people once went down the tree, but Zhang Shuang was attacked by the man-eating beast, one of his faces was bitten off, and he fell down, and he couldn't even find the bones.

No one could have imagined that Zhang Shuang, whose face had been bitten off and had died, suddenly reappeared in the canopy of this immortal tree like a ghost, and even snatched the military waist knife in Du Changde's hand, and stabbed Du Changde in the chest and heart with a knife, kicking him down.

Like Xiao Ling, this change shocked everyone, this cool hand was agile, like an ape, killed Du Changde, and with a flicker, he wanted to pounce on Yu Tingting, who was only two meters away from him.
