Yang Xiaotian and the two flew quickly towards the cave.

However, when coming to the cave, the dark dragon had been paying attention to the changes in the corpse river, and beware of the terrifying beings in the corpse river.

When I came to the gate of the cave, I saw that the gate of the cave was closed, and there were runes imprinted on it, even if millions of years had passed, these runes were still shining.

The entire cave is not cast with fine iron, but with huge animal bones, which exude an amazing corpse aura.

The corpse was rolling, and there was a faint mournful sound.

Obviously, these corpses have turned into spirits.

Yang Xiaotian was shocked, what kind of beast bone is this, and the corpse qi can actually turn into a spirit.

"This should be the corpse beast in the corpse river, after being killed by the Huangquan Patriarch back then, he used his bones to refine this cave mansion." The dark dragon said with a solemn face, "These corpse qi have turned into spirits, and they are very troublesome."

Even he said it was very troublesome, which shows the horror of these corpses.

Yang Xiaotian tried to urge the power of the Eternal God Body, and his fists burst out.

Suddenly, the power of time blasted into the rolling corpse qi.

A terrible howl rang out.

What surprised Yang Xiaotian was that his time power could only make the rolling corpse qi lighter, and could not completely assimilate these corpse qi.

Moreover, Yang Xiaotian's attack made the originally calm cave light vibrate, and endless corpse qi gushed out, roaring towards Yang Xiaotian and the dark dragon.

Yang Xiaotian was startled, and the dark dragon hurriedly retreated, until they reached the entrance and exit of the underground, and the gushing corpse qi from the cave stopped.

It is no wonder that the Huangquan Patriarch Cave Mansion has always been well preserved, even if someone can enter this underground corpse river, it is extremely difficult to enter the Huangquan Patriarch Cave Mansion.

Yang Xiaotian had no choice but to let the dark dragon wait for him outside, and then let Ding Ye protect himself with a light shield and come to the gate of the cave again.

Yang Xiaotian put his palms on top of the gate, trying to manipulate the power of the Eternal Divine Body to see if he could assimilate the gate.

What made Yang Xiaotian happy was that under the power of the Eternal God Body, the gate was assimilated little by little, although the speed was very slow, but at this rate, it could be assimilated in a tea time at most.

Just as Yang Xiaotian continued to assimilate the gate of the Cave Mansion, Yan Ping, the immortal god of death and the son of the god of the underworld, also came to the main hall of the Huangquan Demon Gate.

The Immortal Reaper looked at the terrifying fist power that stretched to the end, and there were some fluctuations on his expressionless face.

"The first demon gate back then, but it ended up like this, it's a pity!" Yan Ping, the son of the god of the underworld, looked at the Huangquan Demon Gate Hall in front of him and sighed.

The Huangquan Demon Gate was destroyed, and he had just broken through the Divine Spirit Realm.

When the Huangquan Demon Gate was destroyed, the news came out and shook extremely in the Cangshen Continent.

"It's just a matter of winning and losing." The eyes of the Immortal Reaper returned to indifference, and he and a few others continued to fly towards the Yellow Spring Forbidden Land.

Underground in the forbidden land, under the power of Yang Xiaotian's time, the gate of the cave was finally assimilated.

Looking at the big hole in the gate of the cave, Yang Xiaotian was overjoyed and flashed in.

In the cave, the corpse qi is even stronger.

However, with the support of Ding Ye's light mask, Yang Xiaotian shuttles freely in the cave.

The space in the cave was bigger than he had imagined.

The front hall alone is several kilometers in size.

Yang Xiaotian walked around, didn't find anything useful, and walked to the backyard.

In the backyard, there was a towering giant tree.

This giant tree is all bones, even the branches are bones, and on the branches, there are more than a dozen fruits.

These dozen or so fruits exude an astonishing aura of death, but there is a divine light circulating on the surface.

"What is this?" Yang Xiaotian was shocked.

"The Tree of Death." Ding Ye said.

Death Tree!

The tree in front of him turned out to be the Demon Gate Treasure Death God Tree.

"Master Ding, is there a way to take away this Death God Tree?" Yang Xiaotian asked.

This Death God Tree, if it is obtained by the Demon Gate masters such as the Immortal God of Death and the Undefeated God of the Underworld, the strength of the Immortal God of Death and the Undefeated God of the Underworld will be able to be cultivated

Refining to an astonishing realm, this Death God Tree naturally can't stay.

"This Death Divine Tree, like the original Heavenly Dragon Divine Tree, has been linked to the power of the entire Cave Mansion, and it is difficult to take it away!" Ding Ye said, "If you want to take it away, you have to consume the Nine Heavenly Tribulation Thunder Water."

Yang Xiaotian frowned.

"However, you don't have to worry, this Death God Tree is impossible for others to take away." Ding Ye said.

Yang Xiaotian nodded, jumped up, and picked all the dozen or so Death Divine Fruits.

These dozen or so Death Divine Fruits contain terrifying death qi, although he can't refine them, but if he takes them first, he may be of great use in the future.

After collecting all the divine fruits, Yang Xiaotian tried to use the power of the Eternal Divine Body to see if he could destroy this Death Divine Tree, but as soon as the power of his Eternal Divine Body touched the body of the tree, it was dispersed by the power of the tree body.

It seems that the Death God Tree has been connected to the power of the Cave, and with his current strength, it cannot be destroyed.

Yang Xiaotian couldn't, so he could only go inside, looking for a way to refine the ancient heavenly coffin.

After a while, he came to a palace.

Inside the palace, there are countless books.

Amazingly, these books have been eroded by corpse gas for many years, and they are still intact.

Yang Xiaotian stepped forward and took a cursory look, all of them were the magical powers of the Huangquan Demon Gate, the swordsmanship, and many handwritings left by the Huangquan Patriarch.

Seeing this, Yang Xiaotian took away all these books and went back to read them later.

Subsequently, Yang Xiaotian found the alchemy room of Huangquan Patriarch again.

In the alchemy room, there is a big tripod that exudes dead air, and the body of the big tripod is branded with a river of corpses.

It seems that this is the Huangquan Corpse River Ding, one of the great gods of Cangshen.

Yang Xiaotian didn't go to refine, and directly took away the Huangquan corpse Heding.

In the alchemy room, there were many alchemy books, and Yang Xiaotian also moved them all.

Yang Xiaotian continued to search for the Heavenly Mandate Divine Stone in the cave.

He entered the ruins of the Huangquan Demon Gate this time, mainly for the Heavenly Destiny Divine Stone.

It's just that Yang Xiaotian searched all corners of the cave, but he never saw the Heavenly Destiny Divine Stone.

Isn't the Heavenly Destiny Divine Stone here?

Just when Yang Xiaotian was puzzled, suddenly, there was a roar and the roar of the dark dragon from outside the cave mansion.

Yang Xiaotian hurriedly flew outside the cave.

As soon as he flew out of the cave, he saw the figure of Yan Ping, the son of the immortal god of death.

The dark dragon is being besieged by the corpse demon, the blood demon, the evil Buddha, and the Brahma sword god.

Since the strength of the dark dragon has not fully recovered, coupled with the fact that the four corpse demons have joined forces, the dark dragon has been forced to retreat.

The Immortal God of Death, the son of the Hades God, Yan Ping, were watching the battle when they suddenly saw Yang Xiaotian flying out of the Huangquan Patriarch Cave Mansion, and both of them were startled.

"Yang Xiaotian!" Immortal Death, Yan Ping and the two spoke in unison.

No way!

How can you run into this kid anywhere?

Seeing Yang Xiaotian, the Immortal God of Death wanted to tear apart the corpse river.

Hearing the Immortal Reaper and Yan Ping exclaim, the corpse demons besieging the dark dragon trembled in their hearts, and they all stopped in fright.

"Master Ding!" Yang Xiaotian roared, and the howling sound shook the corpse river.
