This knife has a fast attack power, but when the big knife of the Shura Ghost Venerable falls on this bone, it can't leave a mark on it.

It's so hard!

It seems that this is most likely the bones of the demon dragon.

"System Analysis!"

At that moment, Zhao Feng just swept over, and then glanced at it.

"Ding! This thing is the tailbone of a powerful immortal beast after death!"

The system prompts.

Now, Zhao Feng can be sure!

Since it is the tailbone of the demon dragon, there may be some clues.

At the moment, everyone was spinning around the tailbone to see if there was anything wrong.

As for the stone demon, it is responsible for digging up the dirt around this tailbone.

"Young master, there is a gap here, and the white mist comes out of here. ”

At this time, Fei Fei made another discovery.

"What?"

Hearing this, Zhao Feng hurried over and found that there was really a small hole with a diameter of one centimeter on the tailbone.

"Stone Demon, go in and take a look!"

Zhao Feng immediately turned the stone demon into a thin needle and drilled into it.

Inside, there is no cave!

That demon dragon was huge, and a single small amputated tailbone could become a big mountain of its own, and his bones were definitely not small.

The stone demon entered the bones at this time, and at that moment, Zhao Feng just broke through the void and drilled in.

Everyone, come in together!

"Haha, fortunately, the stone demon can change a lot, otherwise I wouldn't be able to get in!"

Zhao Feng grinned.

It is impossible for a human to enter through such a small hole, not even an immortal, unless he can chisel through it.

However, this demon dragon is at least at the level of the Nine Heavens Xuan Immortal, even if the bones of the corpse after death are not something that ordinary people can hurt, just now Shura Ghost Venerable has tried, no wonder the Demon Dragon Hall is trapped here, even if they find this small hole, I am afraid there is no way.

"Elder Shura, Shura Ghost Venerable, you two go to explore the way. ”

Zhao Feng said to the two of them, as for him, he was hiding in the body of the Earthquake Heaven, after all, there might be some danger in this place.

As for Fei Fei, she returned to the cultivation space and continued to cultivate. Every day in the outside world is very precious to her.

Sure enough, the inside of this keel was not so simple, and the tree elder and Shura Ghost Venerable who went to explore the path directly sent back the news.

Ahead, there is danger!

"Is it a bone soldier, comparable to the Nine Pinluo Heavenly Immortals?"

Zhao Feng swallowed his saliva, this Nima is too cheating.

The hall master of the Demon Dragon Hall was nothing more than a Jiupin Luo Heavenly Immortal, and three Jiupin Luo Heavenly Immortal-level bone soldiers suddenly appeared in front of him, which was simply incredible.

However, thinking that this demon dragon was at least at the level of the Nine Heavens Xuan Immortal, Zhao Feng calmed down again.

What about the level of the Heavenly Immortal of Jiupinluo, the elder tree can solve it, let alone the Shura Ghost Venerable?

Soon, Zhao Feng rushed over and saw Shu Lao and Shura Ghost Venerable, who were fighting with the three bone soldiers.

"Little Master, although the combat power of this bone soldier is not strong, its defense is amazing, and the bones can't kill them with a single sword!"

"The bone is full of strength, it is enough to hurt the Nine Heavens Xuan Immortal-level master, but this bone soldier should be born after countless years of demon dragon bones, and it is natural that the defense is strong!"

Zhao Feng said slowly.

"Then what should we do, do we break in, or?" asked the tree elder with a frown.

Zhao Feng hesitated for a moment and said, "Shura Ghost Venerable, you catch one, I'll see if I can take him!"

The ghost fire eyes of the Shura Ghost Venerable flickered twice, and almost instantly captured one of the bone soldiers, and as for the remaining two, they were handed over to the tree elder and the stone demon.

"Forced Redemption!"

Zhao Feng approached the bone soldier and cast a forced exchange.

"Ding! Forced exchange failed!"

This bone soldier doesn't know what level it is judged by the system, anyway, with Zhao Feng's realm of the three rank Luo Heavenly Immortals, it is impossible to accept it.

Since it doesn't work, try the next trick!

"A Thousand Absolute Slashes!"

Zhao Feng sacrificed the Fire Immortal Sword and slashed it directly.

"Bang!" "Bang!" "Bang!"

A subtle muffled sound fell into Zhao Feng's ears, and there were two thousand shocks.

It's a pity that this Thousand Absolute Slash still failed to kill this bone soldier.

"It seems that it is tricky!"

Zhao Feng's eyes narrowed slightly, and he thought for a moment in his heart.

"Little master, why don't we stay here for the time being, and when your strength improves, maybe it'll be fine. Elder Shu reminded.

Hearing this, Zhao Feng nodded slightly and said, "Okay, since that's the case, then let's wait for a while and let me break through first!"

He had destroyed the Demon Dragon Hall before, and he had a large number of heavenly and earthly treasures, and at this time, his magic value was back to zero, but since the last breakthrough time had not been long, he was waiting for time.

Then, he tried the other two bone soldiers with a forced exchange, but it was still the same, but it didn't work.

"Stone demon, you trap the three of them, let's wait here for a few days!"

Zhao Feng said to the stone demon.

To be honest, Zhao Feng didn't want to let go of these three bone soldiers, after all, this bone soldier was born from the bones of that demon dragon, this was a Nine Heavens Xuan Immortal-level bone, for him and Shu Lao, it was a huge income, how could he let it go?

When the stone demon heard this, he quickly turned into a round ball, and then the Shura Ghost Venerable threw the three bone soldiers into it one by one, and then trapped them.

These three bone soldiers are only Jiupin Luo Heavenly Immortals, and they can't break through the stone demon's defenses at all, so they can only be trapped inside.

Then, Zhao Feng asked Shu Lao to wait at the end of this tailbone, while he himself went outside.

Time, little by little.

About seven days later, Zhao Feng felt that the time was almost up, so he began to exchange for heavenly and earthly treasures.

"Ding! Congratulations on your breakthrough, you are currently a Sipinluo Heavenly Immortal!"

"Ding! The Ember of Thunder and Fire has broken through, and it is currently the Seven Rank Luo Heavenly Immortal!"

"Ding! The stone demon has broken through, and he is currently the Eight Pinluo Heavenly Immortal!"

"Ding! Shura Ghost Venerable has broken through, and he is currently the Eight Pinluo Heavenly Immortal!"

"Ding! Congratulations on your breakthrough, you are currently a Wupinluo Heavenly Immortal!"

"Ding! The Ember of Thunder and Fire has broken through, and it is currently the Eight Pinluo Heavenly Immortal!"

"Ding! The stone demon has broken through, and he is currently the Jiupin Luo Heavenly Immortal!"

"Ding! Shura Ghost Venerable has broken through, and he is currently the Nine Pinluo Heavenly Immortal!"

"Ding! Congratulations on reaching 60 mana!"

When he broke through to the Four Rank Luo Heavenly Immortals, Zhao Feng cleared the magic value once, and then broke through again, rising sixty points at once.

Then, he exchanged a large amount of heavenly treasures to reset the magic value to zero again.

However, he has almost used up the harvest of the Demon Dragon Hall this time.

"The Five Rank Luo Heavenly Immortals, the Shura Ghost Venerable and the Stone Demon have also arrived at the Nine Rank Luo Heavenly Immortals, and now our strength should be enough to kill a bone soldier, right?"

Zhao Feng said secretly in his heart, and then let the stone demon release a bone soldier.
