"What the hell, you dare to yin me!" Yi Tian probed his brain into this giant cave and carefully examined the situation.

He sensed that this strange tree, which had just been manipulated by a mysterious force, had launched an attack on him.

Because he felt that this strange tree, unlike the abyssal demon tree in the Crowned Niuxun Rainforest, had its own consciousness, and was half plant and half creature.

This strange tree is like a pure weapon, manipulated by man.

And the mysterious power to control the strange tree comes from this pit underground.

He felt that there might be something unclean in the pit.

"I want to see what the hell is in the pit deep underground here?!" Yi Tian was not afraid at all, how could he be afraid of this kind of pit as an abyss seed?

With a stagnation of his wings, he flew straight into the groundless pit with no end in sight.

"Whew, Whew, Whew......"

As soon as Yi Tian entered the pitch-black pit, he immediately felt that there was no wind around him, and the yin wind was whistling around, and the gusts of yin wind were terrifying.

Below is a long passage, deep into the ground, zigzag, like a labyrinth, I don't know where it leads.

Yi Tian felt that deep underground, something inexplicable was secretly observing his every move.

He reached the underground, and deep underground, the ground was no longer as rancid as mud, but as hard as rocky ground.

"Click......"

There was a sound of joint movement in front of him, and a snow-white skeleton walked towards him with stiff steps.

"Sure enough, there are undead creatures," Yi Tian looked at the skeleton man carefully, "This skeleton doesn't seem to be conscious!"

He noticed that there was a flame in the skull, a flickering in the darkness.

Although the skeleton had a stiff pace, when it saw Yi Tian, it immediately took action, pounced from the side, and quickly approached Yi Tian.

"Look for death!"

Yi Tian stepped on the skeleton with one foot, as simple as stepping on an ant, and the fire in the skull disappeared without a sound.

He began to make his way slowly into the depths of the tunnel.

Although the five fingers were missing from the pit, it did not have a big impact on Yi Tian, and everything came into view clearly.

In the darkness, the tunnels in the pit grew wider and wider, and groups of skeletons appeared inside.

Those skeletons are not only humanoid, but also beast-shaped, strangely shaped and everything, and from the current appearance, it is completely impossible to see what it was like before birth.

Their bones are as hard as iron, and after death, they are affected by the evil qi around them, and all of them are transformed into undead spirits, becoming skeleton monsters.

There is no doubt that this space is a world of the undead, and under the nourishment of boundless evil energy, there may be countless undead monsters.

And this underground tunnel is extremely huge, like a labyrinth, all kinds of tunnels are staggered, extending in all directions, and I don't know where it leads.

Yi Tian did not have the slightest fear, and went directly towards the deepest place in the ground.

As he went deeper and deeper into it, the evil qi in the tunnel became more and more intense, and if ordinary creatures came in, it was very likely to be eroded by the evil qi and become undead or zombies.

Only an abyssal species like him, or a creature with extremely high resistance, is immune to the erosion of these evil qi.

"There won't be any thousand-year-old zongzi in this!" Yi Tian felt that the environment here was a little terrifying.

He seriously suspected that he would encounter an old corpse in the mountain in a pit.

"No matter what you are, you dare to yin me, even if you are an old zongzi, Lao Tzu will gnaw you too!" Yi Tian gritted his teeth, very unhappy.

He sped towards the depths of the tunnel, undaunted.

dared to go deep into the ground, not only by virtue of his identity as an abyssal species.

And the "Abyssal Furnace" has the ability to refine all kinds of xenomorphic energy.

These evil gases, corpse gases, miasma...... For him, it's all a great supplement.

Yi Tian was covered in black light, and he activated the ability of the Abyss Furnace.

With himself as the center, there are dozens of kilometers of corpse qi, evil qi, and miasma...... They all converged on him, forming a vortex, all of which he absorbed into the abyssal furnace within his body.

The thick black fog around them has dissipated a lot.

Yi Tian felt that he was full of physical strength, and his energy was constantly surging.

These are made up of corpse gas, evil spirits...... Although the energy converted is extremely limited to his strength, no matter how small the mosquito is, it is still meat.

Yi Tian ran rapidly in the tunnels, skimming one underground passage after another, which led in all directions, some were dead ends, and some were bifurcated passages.

As he went deeper, there were more and more skeleton monsters in the passage.

Some of the skeletons were like white jade, and the flames of their souls were flashing in the eyes of the two black holes.

They already had a faint consciousness, knowing that Yi Tian was not easy to mess with, and no longer rushed up to death without brains, but scattered and fled in all directions.

Along the way, Yi Tian has also killed many skeleton monsters.

He found that these things were really low-level, and they couldn't even contribute 1 abyss value.

Killing them is a complete waste of time.

Yi Tian didn't chase and kill, but only killed some of the skeleton monsters that didn't open their eyes and stood in the way.

"Boom ......"

A pitch-black beast-shaped skeleton monster appeared, opened its mouth and roared, and suddenly a raging flame appeared in the pitch-black bone mouth.

This flame is pitch black, extremely hot, and contains a high degree of poison, eroding the entire ground of the tunnel.

It's a pity that Yi Tian didn't dodge or dodge, he rushed directly over, swept by with a fierce wind, and let the black poisonous fire bombard his body.

He was not bad, and his strong resistance made him immobile in the face of this energy attack.

Yi Tian gathered the power of the abyss on his right claw, and with a "boom", the claw of the earth splitting was swung out.

Then the head of the pitch-black skeleton exploded with a bang, and it was directly blasted to the head.

A fire-like energy flew out, the consciousness energy in the pitch-black skull.

Yi Tian once again spewed out a blazing dragon's breath, and a rolling heat wave swept in all directions, and the other skeletons were burned into a handful of ashes by this power.

He was firing at full speed, speeding through the tunnels, and in an instant, he almost crossed hundreds of underground passages.

He didn't know how deep he had reached.

Along the way, there were more and more skeleton monsters around, and there were also some rotting corpses, ancient corpses, jumping towards him.

"Roar, roar........" Suddenly, a roar came, and a powerful consciousness locked onto Yi Tian.

Then, a cold light flashed, and it surged out from the depths of the underground passage, and a powerful ancient corpse appeared.

The zombie was a giant ape, more than 10 meters tall, dead for an unknown number of years, holding a huge stick.

The big iron rod was more than 30 meters high, mighty, and the evil aura spread out all over his body, with a fierce killing intent, and roared wildly towards Yi Tian.
