Guan Yu, who returned to Daye City, did not go to the street of the law enforcement team, but entered the Xiong family's old mansion.

The old house was empty, and the door was closed.

Guan Yu found a room to live in, and then meditated cross-legged.

His current cultivation can indeed kill a ninth-level earth immortal in an instant, or even a tenth-level one, as long as he sneaks in or assassinates, he can easily kill him.

But there are also great drawbacks to their own conditions.

For example, if he didn't rely on his mental strength, his pure physical strength was not as strong as the Immortal Yuan of the ninth-level Earth Immortal.

For example, his physical strength still can't support the continuous burst of mental strength.

Now it's only a maximum of seven punches, and after seven punches, the body can collapse, so the strength of the body is still weak.

Besides, the mental strength did not seem to be endless, because after this battle, he found that the mental strength of the heart was decreasing. That's right, he now faintly saw that the heart strength of the heart had decreased by about one-third, because the color of the heart had changed, and the upper third of the heart had also failed, as if there was a bottle of water, and now he drank one-third of it, and there were two-thirds left.

Therefore, as his heart keeps beating, his heart will fail sooner or later.

He didn't know if he would die if his heart failed, or if it would continue.

Or is it that after a period of recuperation, one-third of the exhaustion will automatically replenish itself?

However, he felt that this probability should not be large, after all, the mental power is not the immortal yuan power is not the true yuan power, and an unknown power, he can't add it, so if the mental power disappears in the end, it will be an eternal disappearance.

The mental energy he is using now is all left over from the fused heart, and no amount of money can be made up.

"How do I replenish the power of the heart? What kind of power is this power, and where can I find it?" Guan Yu had a headache, if he didn't have the power of the heart, he would be nothing.

Maybe he can also kill a ninth-level earth immortal, but he won't have any confidence at that time.

"You have to strengthen yourself. Guan Yuyu thought for a long time, and then made a decision.

First, continue to absorb the Xingchen Enlightenment, as long as he can open more than thirty-six Orifices, then he can kill the enemy with the power of the simple acupuncture.

Second, he must also cross the catastrophe and strive to reach the Feather Transformation Realm, if he covers his breath when the time comes, he will not be able to soar, so that he can keep replenishing the Immortal Yuan, and he can use the Star Absorbing Great Law to keep sucking, not afraid of being exploded.

Third, look for things that replenish your mental strength.

Guan Yu made up his mind, and then began to prepare, he should have crossed the Ninety-Nine Heavenly Tribulation a long time ago, but he didn't dare to break through the last line of defense, and he didn't dare to continue to absorb.

But now he had a certain idea, he immediately retreated from the Yellow River Scroll, and began to absorb a large number of spiritual energy stones and various pills in the space ring.

"Huhu~" One by one, the aura stones were consumed, and they turned into powder in an instant, and after using tens of thousands, a sudden pressure appeared in his heart.

The doom is coming.

He immediately put on the yellow robe, and escaped from the mansion, and quickly ran out of the city.

After a while, he left the city, and then kept teleporting eastward, and after a dozen times, he had come to the Eastern Wasteland, but he did not stop, but continued to fly in the direction of the East China Sea.

After a day's flight, he reached the depths of the sea.

In this deep sea, there are not even islands, he flew away for a day, not to mention millions or even tens of millions of miles, and there is no one here at all, even if it attracts a huge catastrophe, no one will find out.

As he withdrew his yellow robe, there was a sudden pressure in the sky, followed by a convergence of dark clouds.

Guan Yu continued to prepare silently, this is the Ninety-Nine Heavenly Tribulation, and basically no one in the Heavenly Machine Domain dares to cross this Tribulation, because no one can survive it.

A monk in the Tribulation Period has accumulated a maximum of a few hundred years, and how can a few hundred years of cultivation be able to withstand the ninety-nine eighty-one heavenly thunderbolts?

Therefore, the monks of the Heavenly Machine Domain, 99.9% of them will not survive the Ninety-Nine Heavenly Tribulation, and most of them will transfer to the Earth Immortal after the Sixty-Nine Heavenly Tribulation, and they do not need to cross the Ninety-Nine Heavenly Tribulation.

In the Heavenly Machine Domain, there are many ways to cultivate the Earth Immortals, and as long as you practice the Earth Immortal Law, you can usher in the Earth Immortal Tribulation, and then there will be no Ninety-Nine Heavenly Tribulation, it will only be a thousand Earth Immortal Tribulation, so that the twelfth time can become an immortal.

But in the past 12,000 years, the vast majority of them have died and disappeared, or in other words, none of the 10,000 earth immortals have ascended.

Millions of earth immortals may not have become immortals, how many years, I have never heard of any earth immortals in the Heavenly Machine Domain who have successfully ascended, either died in the process of crossing the nine tribulations and ten tribulations, or died in the eleventh tribulation.

Therefore, there are very few of the Ten Tribulations in the Heavenly Machine Domain, none of the Eleven Tribulations, and as for the Twelve Tribulations, I am afraid that only the Forbidden Sea will appear.

Guan Yu can be regarded as having accumulated savings for many years, and his physical body and his own soul realm have reached a certain level, and he still has mental strength, artifacts and immortal weapons, so if nothing else, this Ninety-Nine Heavenly Tribulation will be successful.

Before, he was worried that he would be led after the successful crossing, but now he didn't have to worry because he had a scroll of the Yellow River.

Naturally, after he succeeded in crossing the tribulation, he was not an earth immortal, but a feather realm. If you want to go to the Spirit Gate, you can still go, because the Spirit Gate does not allow the Earth Immortals to enter, and feathering is no problem.

Even if the feather can't be entered, Guan Yu can still simulate the breath, so it's not a problem.

Guan Yu waited for an afternoon before the clouds of calamity were gathered, and then the first thunder fell from the sky.

The first one is not strong, that is, the power of ordinary lightning, Guan Yu stood in the sky and didn't even move, letting the thunder slash above his head.

The second path is a little stronger than the first, then the third path continues to strengthen, and then the fourth, fifth, and sixth paths...... Until the ninth road, Guan Yu suddenly laid down layers of defense, this calamity is also nine roads and nine sections, the ninth road is a big hurdle, the first eight roads are like tickling, but when it comes to the ninth road, Guan Yu feels that the crisis is coming.

"Boom~" silently, the ninth thunder was mixed with a purple light, just like the last thunder of the main ferry of Qingfeng Island, exactly the same!

Guan Yu held both hands to the sky, and then the thunder directly shattered his defenses, scorched his palms, and drilled into his head through the gaps in his palms!

"Boom~" Guan Yu only felt that his soul was like an explosion, and the whole person lost consciousness instantly, but then, Guan Yu instantly woke up again, and his eyes were cold.

Thunder Tribulation was slashing his spiritual sense.

He had a spiritual attack, and it was also because of the accident when he crossed the Sixty-Nine Heavenly Tribulation, and he remembered that the end of that split made him have an extra spiritual light in his mind, and that spiritual light was a spiritual attack. And now, there is still an aura in the thunder tribulation, which should be to destroy the spiritual consciousness that he appeared!

He vaguely guessed that this Heavenly Dao rule did not allow the spirit sense to attack this kind of technique, because it was a god-destroying technique!

"Whew~" Guan Yu took a deep breath: "Since you want to destroy me, then I will use the Thunder Tribulation to strengthen my spiritual strength." "He had already discovered that his spiritual sense attack was not of obvious use to high-level earth immortals, and it could only confuse the opponent's consciousness in an instant, so if he wanted to become stronger, he could only absorb the spiritual light in the thunder tribulation!

Thunder Tribulation is the law of heaven and earth, when someone else crosses the tribulation, the thunder will not attack your spiritual sense, but when he crosses the tribulation, the thunder also appears spiritual light, to destroy his spiritual sense.

Guan Yu wants to take this opportunity to continue to increase his spiritual strength!

When the tenth thunderbolt slashed down, Guan Yu saw a larger purple light, or spiritual light, and the thunder wanted to continue to destroy the spiritual consciousness that appeared in him!

"Star Absorbing Great Law!" Guan Yu roared and rose to the sky, the Star Absorbing Great Law was running to the extreme, he was about to suck the thunder aura!
