The entire Undying Mountain, and all the monsters there, were completely dumbfounded.

They never expected that Chen Xuan would possess such a treasure as the World Tree.

"Since you know that, then come and be fertilizer!"

Chen Xuan grinned.

What is his purpose in coming to the Undying Mountain?

Isn't it just to use these guys as fertilizer?

Before leaving the Undying Mountain last time, he had already captured an Emperor-level monster and experimented on it.

At that time, the World Tree drained the emperor dry, but later it was resurrected.

So now, Chen Xuan treats them as a continuous source of power.

Snap!

Chen Xuan's large hand struck out again, this time aimed at the red Undying Twin Venerables.

The latter naturally resisted with all their might.

But it was all for naught!

Chen Xuan slapped him a few times, leaving him dizzy and disoriented, as if his brain had been shaken to its limit, and he was completely out of his mind.

Then, using the same trick again, they imprisoned him with the laws and sent him to the World Tree.

The lush, leafy world suddenly rustled with activity, moving without wind, making excited sounds.

One of its branches extended out, its lush green leaves gently brushing against Chen Xuan's face, as if it were being affectionate.

It possessed basic knowledge and knew that Chen Xuan was its master.

At the same time, six roots broke through the Xuanhuang soil and inserted themselves into the limbs, brows, and dantian of the red immortal duo.

The roots and stems frantically absorbed the power within it!

"ah!"

The red Undying Duo also let out the same miserable scream as the black Undying Duo.

He felt his power being drained away little by little!

He is like a pond, filled with water!

The World Tree, like a relentless pump, is rapidly draining the water from his pond.

He struggled desperately, but no matter how hard he struggled, he couldn't break free!

They could only watch their strength being mercilessly drained away, little by little, without any chance to resist!

"Stop watching the show, everyone come over here!"

The strange emperors around them were terrified.

Their leaders, the two immortal lords, were as vulnerable as chicks in front of Chen Xuan!

How the hell are we supposed to fight this?

They immediately tried to escape and hide in their cave.

This is, after all, the Undying Mountain. As long as they hide deep enough, they feel that Chen Xuan won't be able to find them so easily for a while!

However, how could Chen Xuan let them leave?

He simply grabbed them with his large hands, one in each hand.

Soon, he captured 23 of the 24 strange emperors of the Undying Mountain and threw them all in front of the World Tree.

These are all minor minions; the World Tree doesn't need to send six roots to insert into their bodies to absorb power, just one root is enough.

Twenty-three white roots took deep root in the bodies of the twenty-three emperors, frantically absorbing their power.

"No, no!"

They cried out in pain and tried to struggle, but no matter how hard they struggled, it was to no avail.

Faced with absolute power, they were completely helpless!

"Roar!"

The Fighting Saint Ape roared at Chen Xuan, opening its blood-red maw and spitting as it lunged forward to tear Chen Xuan apart.

However, Chen Xuan directly imprisoned him using the laws of space and time.

After all, he was the monkey Gu Kong's uncle, and he was forcibly controlled by the Undying God and had his consciousness erased. He did not fall into depravity voluntarily, so Chen Xuan would not touch him and did not use him as nourishment for the World Tree.

Besides, after losing that half of the black iron rod, the Fighting Saint Ape had been bullied by the other twenty-odd Great Emperors in turn, which was rather unlucky and pitiful.

The World Tree is growing rapidly at a rate visible to the naked eye.

The power of these monsters is a great tonic for it!

"My God! Will the master one day grow the World Tree to be as big as a great world?"

The big black ox stared dumbfounded at the ever-growing World Tree, swallowed hard, and was overwhelmed with shock.

"This guy is a real scoundrel. He actually used other people's bodies as nourishment. He's even worse than the King of Hell in the underworld."

Dugu Rou couldn't help but complain.

She felt that she was a person with a lot of clever ideas.

But looking at Chen Xuan now, this guy is cunning and has even more tricks up his sleeve.

At least, she couldn't imagine using living people as fertilizer for trees, treating them like the dead.

"No, I... I'm dying..."

Among the twenty-three bizarre emperors, one who looked like a long worm spoke in a weak voice.

It is a centipede with a thousand legs, and its full size is hundreds of kilometers long.

But now, it is only a few dozen kilometers long, and it is skin and bones, looking extremely weak.

"Old Black, get down!"

Chen Xuan shouted loudly.

"Master, I'm here!"

The big black bull let out a strange roar, not knowing why Chen Xuan had suddenly called him. Without thinking twice, and knowing that it wouldn't harm him, he charged down first.

Chen Xuan grabbed the weakened centipede with his large hand, and the roots of the World Tree were pulled from its body.

Chen Xuan flicked his hand, hurling the centipede directly at the black ox, and ordered, "This centipede is extremely weak. You, kill it!"

"Huh? Me?"

The big black ox was dumbfounded.

Although the centipede was already very weak, it was still a powerful emperor!

But he, Da Hei Niu, was merely a Great God Emperor.

How am I supposed to fight this?

However, the centipede had already come crashing down, and Big Black Bull had no way to dodge it; he could only grit his teeth and face it head-on.

For a time, the two sides fought fiercely and evenly!

Originally, the Black Ox was suppressed by the Undying Dao and could not fly in the Undying Mountain. However, Chen Xuan used the Undying Law to possess him, freeing him from the suppression of the Undying Dao.

An hour later,

puff!

The weakest of the strange emperors finally succumbed to the World Tree's absorption and was completely drained, his body turning into bones.

His bones were blasted into powder and scattered into the yellow earth, where they served their last bit of nourishment.

However, in just a few breaths, a pool of black liquid appeared at the bottom of the Undying Mountain, and his body floated up from the black liquid.

He was resurrected.

Seeing this, Chen Xuan naturally didn't hold back and grabbed him with his large hand, continuing to let the World Tree absorb the energy.

Pfft!

This time, the two eerie emperors were drained dry by the World Tree, their bones even shattered, yet their ashes were still absorbed by the Xuanhuang Soil, without wasting a single nutrient.

Soon, the two of them were also resurrected and captured again by Chen Xuan's ruthless iron hand.

Puff puff puff!

In less than the time it takes for an incense stick to burn, three more eerie emperors exploded!
