In order for an immortal cultivator to become an immortal, he must go through three rounds of heavenly tribulations.

The small catastrophe of the Jindan period.

The middle heaven tribulation in the infancy period.

and, the Great Tribulation that broke through to the Tribulation Period.

Now, Han Lidu is the Great Heavenly Tribulation, in addition to the Nine Heavenly Thunders, there are also Wind Tribulation and Heart Tribulation.

The so-called wind tribulation refers to the samadhi divine wind, the earthly evil wind, and the heavenly evil wind.

As for the heart tribulation, it refers to the attack of the inner demons.

The demons belong to a special kind of demons, they do not have a physical body, but exist in the form of spirits, they are good at seducing, creating illusions, once they fall into it and cannot extricate themselves, it will lead to the depletion of the soul.

The clouds in the sky had dispersed, and winds began to coalesce around.

Cheng Bo can sense that the condensed wind has a biting coldness, but there is a sense of dignified and upright, this should be the samadhi divine wind.

He withdrew from the confines of the mansion and left Han Li to survive on his own.

Soon, the three divine winds condensed and formed, blowing towards Han Li in the mansion.

However, the formation outside the mansion lit up again, greatly reducing the power of the samadhi divine wind, and when the remaining small samadhi divine wind fell into the mansion, it could no longer pose a threat to Han Li.

An hour later.

Han Li successfully defused the samadhi kamikaze.

Then, a great deal of wind poured out of the ground, enveloping him as if it were about to swallow him.

In this regard, Cheng Bo is not worried, even if this Taizhen Immortal has no arrangement, with the life essence in his hand, even if he is seriously injured, he can quickly recover to the peak.

Sure enough, as Cheng Bo expected.

Han Li survived the storm very easily.

Then the calamity came.

The three-headed Heavenly Demon walked out of the void separately and instantly locked on to Han Li, turning into three streams of light and shooting towards him.

"Bang! bang!"

The three demons were all rebounded by the formation outside the mansion.

And Cheng Bo, who had been observing this scene, showed a little heartbeat.

This heart demon seems to be all spiritual spirits, if he can refine and devour them, it will definitely be of great benefit to his spiritual cultivation.

However, the inner demon will be dangerous to Han Li, but it is not an opportunity to hone his state of mind, so he is a little hesitant.

"Forget it, just grab one!"

Now that he has made a decision, Cheng Bo directly used his spiritual power to form a large net to envelop a demon.

After a brief panic, this heart demon immediately calmed down, and then turned into Ma Zhenzhen's appearance.

I have to say that the heart demon's ability to perceive people's hearts is too strong, and he can actually capture some of Cheng Bo's memory fluctuations in an instant, and thus become a certain character in his memory.

turned into Ma Zhenzhen's inner demon and began to pose, trying to lure Cheng Bo.

But how hard Cheng Bo's mind is, how can a small heart demon be tempted, so, as soon as his mind moved, a spiritual transparent flame appeared in the spiritual net, and the demon was burned wildly.

"Don't Cheng Bo, I'm real, don't you love me, let me go, okay?"

"Ma Zhenzhen" struggled painfully while begging Cheng Bo for mercy.

"Put away your little trick and die obediently!"

Cheng Bo sneered.

Next, the inner demon kept changing his state, constantly changing into his woman's appearance, but Cheng Bo was unmoved.

Eventually, the inner demon was refined into a fist-sized mass of spiritual power.

Then he was directly included in Zhihai.

At the moment when this spiritual power entered the sea of knowledge, it suddenly came to life and shot towards his soul.

"Huh!"

Cheng Bo smiled disdainfully, and his spiritual power turned into a tentacle monster, which instantly restrained this spiritual power, and the roots were deeply rooted in it, instantly crushing the last core of the heart demon.

As soon as the core of the heart demon was shattered, it completely died, and the remaining posture was a ball of pure spiritual power.

Running the "Thunder Sound Spirit Diagram", this group of spiritual power was quickly absorbed by his spiritual power.

Half an hour later.

This group of spiritual power and Cheng Bo's spiritual power were completely integrated, which made his spiritual power grow a lot, and he was getting closer and closer to the seventh-order spiritual master.

Exit the sea of knowledge.

Cheng Bo's gaze fell on Han Li's body.

Those two heart demons have broken into the mansion, although they have been weakened, but they still bring a certain amount of trouble to Han Li, until now, Han Li has not escaped from the predicament, but has fallen into the illusion created by the heart demon.

Cheng Bo didn't have much to worry about this, firstly, he helped kill one heart demon, secondly, the formation weakened the strength of the other two heart demons, and finally, Han Li himself also had the strength of a fifth-order spiritual master.

What's more, he is still the protagonist of this world, and he has an atmospheric possession, so he doesn't think that the two-headed demons have no choice but to get him.

Really.

Two hours later, Han Li still broke away from the illusion created by the heart demons, and took the opportunity to kill the two heart demons, and then refined and absorbed them, becoming part of his spiritual cultivation.

But his expression was a little embarrassed, obviously, in the illusion, he had experienced a lot of things.

As soon as the heart demon died, it meant that Han Li had officially stepped into the early stage of the tribulation.

The next moment, he stood up, walked out of the mansion with steps, and bowed to Cheng Bo: "Big brother, thank you for your help!"

"Second brother, don't blame the eldest brother for stealing your opportunity, the eldest brother is already very satisfied, why thank you!" Cheng Bo smiled.

"How so!"

Han Li also smiled, the inheritance left by the Taizhen Immortal was very strong, even if he was only in the early stage of the Tribulation, but during the Tribulation Period, his strength could almost sweep, and this place was brought to him by Cheng Bo, so he didn't blame Cheng Bo at all in his heart, but was very grateful to him.

Soon.

The three of them reunited in the spaceship.

Cheng Bo gave Han Li and Zhang Ying the elixir that the immortal medicine had refined, and these potions could at least allow them to break through to the late stage of the Tribulation.

At the same time, Han Li informed Cheng Bo that he had obtained one of the nine great inheritances, and he could barely be recognized by this world, and he could leave here at any time.

But Cheng Bo suggested that Zhang Ying survive here.

After entering the elixir, Zhang Ying entered the retreat again.

Three months later, Zhang Ying's catastrophe came.

The clouds were condensing, but Cheng Bo squinted, whether he could break through to the seventh-order spiritual master would depend on this time.

"Boom!"

The first thunderbolt fell.

As soon as Cheng Bo's body flickered, he intercepted the thunder first, and introduced the thunder energy into Zhihai to refine his spiritual power.

Together.

Two courses.

Three courses.

At the sixth thunderbolt, Cheng Bo sensed that his spiritual power had reached a critical point and began to enter a metamorphosis.

But he didn't break through right away.

Instead, he helped Zhang Ying withstand the rest of the thunder tribulation, and then officially entered the breakthrough.

"Third sister, if you can't bear it, take the life essence!"

Cheng Bo gave an order, then dodged to the side and broke through seriously.

I don't know how long it took.

Cheng Bo Zhihai's spiritual power has finally completed its transformation, and he has officially stepped into the seventh-order spiritual master.

Compared with physical cultivation, spiritual teachers are more powerful, and this profession is also more thoughtful.

It is not uncommon for a seventh-order spiritual master to kill an eighth-level physical cultivator, and it can even compete with a ninth-order physical cultivator.

If the seventh-level physical cultivation has the qualifications to be knighted, then the seventh-order spiritual master will definitely be knighted.

"Whew!"

Cheng Bo exhaled a breath of turbidity, raised his eyes to look at Zhang Ying who was in the tribulation, and then his face sank, and he found that Zhang Ying's soul breath was actually constantly weakening, obviously she had fallen into the environment created by the demon and couldn't extricate herself.

Han Li was watching anxiously from the side, helpless.

"Big brother, the third sister's situation is very bad!"

Han Li said.

Cheng Bo nodded, indicating that he knew.

Time passed slowly, Zhang Ying's soul aura weakened faster and faster, and there was no intention of breaking away at all, if it continued like this, it would not take two hours for her soul to completely die.

"What should the eldest brother do, if it goes on like this, the third sister will die!"

Han Li shouted anxiously.

Cheng Bo's face was also quite gloomy, and after pondering for a while, he said: "The only way to save the third sister is to enter the illusion created by the heart demon and wake her up, but this will be very dangerous, because the three-headed heart demon has devoured part of the third sister's soul and has become very strong! It's not easy to deal with them!"

"Big brother, let me go!"

Han Li took the initiative.

"No, I'll go, my mental power is stronger than yours, you may not be the opponent of the three-headed demon when you go in! Okay, there's not much time, I'll go in first! Take care of my body!"

As soon as the words fell, Cheng Bo's spiritual power was directly thrown into Zhang Ying's Zhihai, in order to save the other party, he only left a trace of spiritual power in Zhihai, if he was attacked by external forces at this time, it would be very dangerous.

"Hmm!".

In a certain bar, Cheng Bo, who was lying on the booth, slowly opened his eyes.

His expression was a little confused: "Where is this?"
