Dozens of Heavenly Demons were armed with various weapons, and their power was amazing, as if thousands of troops and horses were galloping, and the killing qi shook the Void Realm.

One of the Heavenly Demon Leaders was dressed in blood-colored armor, exuding a terrifying aura all over his body, and with a sword in his hand, he was the first to rush into the void and kill Zhao Yu.

Laugh at!

Zhao Yu immediately struck out, slashing with a sword, and immediately shook the Heavenly Demon Leader into the air with a sword, making him spit blood from his mouth.

"It's not good, this immortal boy's sword technique contains destructive power, if we are slashed by his sword, we will definitely die!"

"Run!"

Seeing that the leader was injured by Zhao Yu's sword, the other Heavenly Demons immediately retreated.

Snort!

One after another, the incomparably powerful sword qi immediately flew in, instantly slashing all the more than a dozen Heavenly Demons at the front.

A moment later, all the Heavenly Demons had fled.

After Zhao Yu repelled the Heavenly Demon, he once again advanced towards the depths of the ancient hall.

Half an hour later, the figure of an old man of the Immortal Clan appeared in the void in front of him, his eyes were cold and his body was lean.

"Golden Immortal-level peak powerhouse!" Zhao Yu's Void Realm Artistic Conception immediately probed the strength of the old man, and his heart suddenly sank, and his face changed greatly.

"I actually met a Golden Immortal-level peak powerhouse, what should I do now?" Zhao Yu immediately shuttled into the Void Realm, and many thoughts immediately flashed in the sea of divine consciousness.

The old man's eyes were like lightning, and he saw Zhao Yu in the void through the void, and then his figure blurred, and he rushed into the void in an instant.

Golden Immortal-level peak powerhouses can also easily travel through the real world and the virtual world, although the virtual world has some constraints on their strength and speed, their strength is too terrifying, and it is still far stronger than Zhao Yu.

Rumble!

Zhao Yu urged the artistic conception of the void with all his might, and frantically shrouded the old man.

However, the figure of the old man can be blurred, merging with the surrounding void, and disappearing in an instant, like a ghost.

Laugh at!

Zhao Yu immediately waved the Green Bull Sword, and one after another sword qi shrouded the surrounding void.

While!

A sword qi flew into a void, and suddenly the void burst with a bang, and then the figure of an old man appeared out of thin air.

Although Zhao Yu's speed and body technique were not as good as the old man's, after he used his Void Sword Technique with all his might, the speed of those sword qi was far above the old man's.

When!when!

The old man only relied on a pair of fleshy palms to block one sword qi after another, and his palm technique was very mysterious, and he could actually dissolve some of the destructive power contained in the sword qi.

Boom! Boom!

A moment later, Zhao Yu suddenly conjured sixteen clones, and then his deity disappeared out of thin air.

Snort!

In an instant, dozens of sword qi shrouded the old man from all directions, and each sword qi contained a trace of destructive power.

The old man faced so many Zhao Yu's clones besieging him, and although he tried his best to defend, he was still in a predicament, after all, it was difficult for his palms to block so many sword qi attacks.

Whoa!

Suddenly, the old man's figure blurred, blending into the surrounding void.

However, after Zhao Yu's deity fully exerted the artistic conception of the Void Realm, the traces of the old man were still discovered by him.

Snort!

After a few breaths, a void was shattered by dozens of sword qi, and then an old man covered in blood emerged.

"I was wounded. The old man looked coldly at Zhao Yu's sixteen clones, and was secretly shocked in his heart.

Laugh at!

Zhao Yu's deity came out of thin air again, and it was very abrupt to stab out with a sword, immediately stabbing the old man.

Liu Mei and a white old man were looking down from the top of the Life Immortal Tree, looking at the ancient hall, and Zhao Yu and the old man were fighting in the ancient hall.

"The realm of this little guy of the Immortal Clan is only a quasi-golden immortal realm, but his strength can be compared to a peak powerhouse of the golden immortal level. The white-haired old man muttered suddenly.

"His immortal cultivation talent is even in the Origin Immortal Realm, which can be regarded as a demon level, and his strength has increased more than ten times compared to before entering the Zhong Immortal Mansion. Liu Mei smiled and said approvingly.

Half an hour later, the old man was finally killed under the crazy siege of Zhao Yu's sixteen clones and the deity.

"This time he was able to successfully pass through the Third Tree Cave World again. When the white-haired old man saw this scene, he immediately smiled.

"Master, will he be able to pass through the Fourth Tree Cave World?" Liu Mei suddenly asked after a while.

"I think he has a 450% chance of passing the Fourth Tree Cave World. The white-haired old man pondered for a moment, and then said lightly.

Hearing this, Liu Mei nodded silently.

Swish!

Not long after, Zhao Yu turned into a streamer and rushed out of the ancient hall, and then a mysterious force enveloped him and rushed out of the Third Tree Cave World.

"Hahaha, I succeeded! I actually managed to enter the Fourth Tree Cave!" At this time, Zhao Yu was extremely excited.

Liu Mei and the white-haired old man looked at Zhao Yu's face full of surprise, and they couldn't help but smile.

Zhao Yu continued to fly upwards along the main trunk of the Life Immortal Tree, surrounded by a vast starry sky, countless stars were twinkling, and it was very silent.

"As long as I pass through the Fourth Tree Cave World, I will be able to enter a higher level of space along the Life Immortal Tree and become a disciple of the Zhong Immortal Mansion, and at that time I can get a few Golden Immortal-level treasures. After flying away for half a month, Zhao Yu finally approached the Fourth Tree Cave World, and at this time he secretly said in his heart.

Zhao Yu's gaze fell for a long time in the vast tree cave world in front of him, where there was a dead silence, and there seemed to be nothing.

"Zhao Yu, congratulations on coming to the Fourth Tree Cave World, it is the easiest of all the Tree Cave Worlds, and it may also be the most difficult one. Suddenly, the figure of Liu Mei appeared on the trunk of the Life Immortal Tree beside Zhao Yu, she looked at Zhao Yu with a smile and said.

Zhao Yu hurriedly smiled and nodded.

"Zhao Yu, the Fourth Tree Cave is actually a strange world, you can see with the naked eye that there is nothing inside, but in fact, there are many heavenly treasures hidden in it, but there is also great danger. If you can stay in it for a year and survive in the end, even if you succeed, you can become a disciple of my Zhong Immortal Mansion. After a pause, Zhao Yu said again.

"Thank you seniors for reminding me, I know!" Zhao Yu hurriedly said respectfully.

Zhao Yu has the information of the Qingfeng Heavenly Xuan Realm Human Immortal Clan, as well as the information of Kong De, so he also knows some of the situation in the Fourth Tree Cave World, and countless powerhouses stop here.

"You go in. Liu Mei said suddenly. At this moment, her heart was full of anticipation, since the death of her master, it had been a long time since Zhong Xian Mansion had not had a new disciple born.

Swish!

Zhao Yu hesitated for a moment, and then rushed into the Fourth Tree Cave World.

"Since Zhong Xian Mansion fell into this Heavenly Xuan Realm, there have been countless powerhouses who have entered Zhong Xian Mansion in the long years, this Zhao Yu's cultivation talent can be regarded as the highest one, and it is also the youngest one, his life and death grinding is naturally much less, I don't know if he can break through, I hope he will not fail. Liu Mei watched Zhao Yu rush into the world of the Fourth Tree Cave, and said secretly in his heart.

Although she has the heart to help, she doesn't have the strength. Everything in the Zhong Immortal Mansion was set by her master, and only the powerhouses of the Origin Immortal Realm could break those rules.
