Ling Xiao took Yu Roufei, Xuan Yao, and Killing Heaven and left Xiaoao Palace.

Xuan Yao knew that the relationship between Ling Xiao and Yu Roufei was not ordinary, and he asked to enter the medicine tripod to cultivate.

Over the years, he has been working on the affairs of the Xiaoao Palace, and despite the help of Ling Xiao's elixir, he has only reached the high-level Tianzun strength mountain, and there is still a distance from the Xuan Emperor level, so he took the opportunity to calm down and cultivate well.

Ling Xiao didn't rush to the Heavenly Fortress immediately, but went back to the Northwest Barren Mountains first, wanting to meet the loser boy before leaving, and see what his current situation was.

It's a pity that when he arrived at the land of the Qilin clan, he learned from the old Qilin that the loser boy hadn't come back since he went out with him last time, and he should have gone on a mission.

Ling Xiao left the Barren Mountains with some disappointment, still missing this guy in his heart.

Then he went to Feng's house and picked up his master Feng Qingyuan.

Now that the Feng family has two more sages, Feng Qingyuan no longer needs to worry about what will happen to the juniors of the Feng family, she can rest assured that she will go to the Heavenly Domain with Ling Xiao.

She just didn't expect Ling Xiao to suddenly reach the Holy Rank so quickly, and it was only a short seven or eight years since he reached the high-level Xuan Emperor.

I don't know how many resources and time it took her to get to this point.

After receiving Feng Qingyuan, Ling Xiao immediately rushed to the Dragon Palace and met with the Dragon Maiden.

He didn't tell the dragon girl that he was going to the Heavenly Realm, lest she ask to leave.

Although Ling Xiao really wanted to have a powerful helper like the Dragon Maiden by his side, he knew that it was the best choice for the Dragon Maiden to stay in the Dragon Palace.

"Alright, it's time to head to the Heavenly Mat Fortress!" Ling said with a long sigh after leaving the Dragon Palace.

The explanations are all over, the people who should be seen are also finished, and it's time to leave.

......

The Heavenly Domain is a place that only the Sage can reach, and to get there, you need to go through the ninefold space level.

Those who have not reached the Sage, and those who do not know how to use space power, it is impossible to pass through those levels to reach the other side of the Heavenly Domain.

And this nine-fold space level is at the very edge of this continent, which is the so-called end of the horizon, and it is also isolated by many dangerous Jedi.

Ling Xiao, Yu Roufei, and Feng Qingyuan were already the strongest on this continent, and they sat on top of their respective spirit beasts, tearing through the space at full speed, passing through those dangerous Jedi, and rushing to the very edge of the sky.

With the strength of their Sages, and with the speed of an eighth-order spirit beast, it took them two full years to fly to the edge of the sky.

There are obviously strong spatial fluctuations here, isolating this continent, it is impossible for ordinary people to break the spatial power here and enter the other end, and ordinary saints rarely have that strength to do it, only the peak saint can break through the spatial power here with the help of the power of a high-level holy weapon or an eighth-order peak spirit beast.

Because there are a total of nine spatial power levels here, one layer is much stronger than the first.

"As long as you shuttle here, you will arrive at the Heavenly Fortress!" Ling Xiao sighed lightly, and without waiting for Yu Roufei and Feng Qingyuan to make a move, he gathered all his strength and blasted towards the spatial barrier.

Bang!

The powerful force forcibly forced open the spatial barrier, and a hundred-meter-wide crack burst open in an instant.

Ling Xiao, Yu Roufei and Feng Qingyuan immediately entered this crack and entered another layer of space.

Ling Xiao didn't say a word, and once again broke it.

Ling Xiao forcibly broke through the three spatial barriers in a row, and when it came to the fourth spatial barrier, he was shocked to find that the spatial fluctuations here were obviously much stronger, and the spatial power was constantly distorting, and the chaotic spatial power was surging towards them.

The three of them only felt some pain in their bodies, and they had to immediately mobilize their strength to resist these chaotic forces.

"Although I haven't been to the Heavenly Domain, I also know in some ancient books that this ninth-layer space power is by no means idle, especially after reaching the fourth layer, there is a chaotic space power that begins to invade our bodies, everyone should be careful, if it doesn't work, let me come" Yu Roufei said.

"I know what you said, but this chaotic space power is nothing, and you will take action later, but...... You'd better put on the defensive armor, the power you will suffer in the back layers will be very terrifying, and you may fall if you are not careful!" Ling Xiao also reminded Yu Rou Fei Dao.

Yu Roufei knew that Ling Xiao's words were right, nodded her head, and attached a Bright Armor to her body.

On the way to Heavenly Domain, Ling Xiao had already returned Yu Roufei's space ring to her.

Although he has not yet obtained her heart and body, the two have a lot of common topics and have become best friends and confidants.

Feng Qingyuan, who was on the side, knew Yu Roufei's strength, and did not steal the merits, and also put on a set of defensive armor, she secretly thought in her heart, "Xiao'er is even more powerful than the evil emperor's brother, and he can actually soak a woman stronger than him as his woman."

Ling Xiao knew that this fourth layer of spatial barrier was extraordinary, and his combat power had increased again, and the golden dragon was illusory

Behind him there was a non-stop roar.

The two fists went out to sea like a dragon and smashed the spatial barrier.

Bang!

A powerful concussive sound, and the ripples of the surrounding space kept floating.

It's a pity that the spatial shield didn't crack like the first three layers.

Ling Xiao was not convinced, his strength increased several times again, and layers of scales had already appeared on the golden fist, and the infinitely powerful punch was enough to be comparable to the blow of a mid-level peak saint.

Bang!

The spatial barrier finally cracked, but this time it was not as cracked as the previous three layers, but only cracked for more than ten meters, and the healing time was quite fast, if the three of them didn't enter immediately, the spatial barrier would close again.

However, when the two of them had just entered the fourth layer, a wave of chaotic spatial forces that were even more powerful than before were blowing towards them.

The space twisted and twisted, and the power strangled at the three of them like sharp blades.

The three of them had no strength to muster their strength to stabilize their bodies and resist these forces.

However, this layer is no longer just the interference of the power of space, only to see the boulders falling like meteors, constantly drifting and coming.

The speed is very fast, and the power is terrifying, if it is hit by any boulder, I am afraid that the average saint will be seriously injured or fall immediately.

Ling Xiao, Yu Roufei, and Feng Qingyuan were taken aback, and hurriedly blasted at the boulders that were floating over, shaking them away.

However, these boulders are like endless, constantly drifting out from other ends, large and small, densely packed, it is simply like a wild explosion of rocks, which is difficult for people to parry.

Ling Xiao's physical body was comparable to a high-level holy weapon, and his fists and feet were like peerless weapons, smashing those boulders endlessly.

Yu Roufei and Feng Qingyuan are not as strong as Ling Xiao's physical body, but their strength is stronger than Ling Xiao's, and every time they make a move, those close boulders are also blasted into powder.

Yu Roufei originally thought that Ling Xiao would not be able to cope with it, and she wanted to help him, but she was relieved to see that he was still so calm and calm, and he brought out super powerful power between his bare hands.

However, she was still a little shocked that Ling Xiao's combat power was no worse than that of a middle-level sage, and she faintly appreciated Ling Xiao a little more in her heart.

Feng Qingyuan relied on the speed of the wind attribute, kept moving, and occasionally made shots, but it was not affected much.

"Don't worry about it here, there are endless rocks here, you must do everything you can to get to the next layer of shielding!" Ling Xiao called out to the two women.

Yu Roufei and Feng Qingyuan responded lightly, and the two of them began to dodge these chaotic stones like swallows, and together with Ling Xiao, they began to sweep towards the next layer of spatial barriers.

The distance between the fourth and fifth floors is not short, and the three of them have been speeding all the way for several days and still have not found a spatial barrier.

It's just that as it goes deeper, the many rocks appear more numerous, the speed of drifting is getting faster and faster, and the force of the impact is even more powerful.

The trio kept dodging, but they were still inevitably hit by a boulder, forcing them to smash it in a hurry.

Ling Xiao still relied on his fists and feet to break stones, while Yu Roufei and Feng Qingyuan had to take out the holy weapons and cut the boulders apart.

The three of them were forced to be unbearable, and Ling Xiao was also hit several times by the boulder, if it weren't for his physical perversion, I was afraid that he would be seriously injured or fall directly.

"No wonder only the Holy Rank can go to the Heavenly Domain, if any martial artist below the Holy Rank comes in, they will already become scum!" Ling Xiao said secretly in his heart.

The impact power of the boulder here is unbearable even for a mid-level sage, and a low-level sage is dead and lifeless when he enters.

"Can you still stand it?" Yu Roufei asked worriedly when she saw Ling Xiao being hit a few times in a row and rushed to his side.

"Don't worry, my body is very hard, these broken stones can't stand me, you help me take care of my master, don't let her get hurt," Ling Xiao responded.

Yu Roufei didn't say much, and immediately went to Feng Qingyuan's side to block more rocks for her.

The three of them rushed forward at a faster pace again, and if another three days passed, the rocks finally began to decrease, but the power of the spatial distortion increased again, and the three of them were breathless.

"Hey, this ...... Could this be the Black Ink Stone?" Ling Xiao slammed his fist on a stone that was not too big, and when he found that he had not been able to break it, he noticed that this stone was different from the others.

Ling Xiao didn't let the stone slip away from him, and looked at it, and suddenly found that this stone was extraordinary.

Black ink stone, a rare stone, is a precious material for refining vessels, no worse than those 10,000-year-old dark stones and 10,000-year-old deep silver, and it is an indispensable material for refining holy weapons.

Such a large piece of black ink stone weighed at least hundreds of catties, and it was difficult to find it in the Middle Domain, and if it was put up for auction, its value would not be worse than any eighth-order spirit grass, or even much higher.

Ling Xiao put the black ink stone away, and then looked at the other boulders and found that there was no black ink stone.

Just as he was about to give up looking, he noticed another piece flying towards him.
