When Zhou Yuan stepped into the Ancient Scripture Building, the darkness in front of him suddenly fell, but the darkness did not last long, but a starlight rose from under his feet and then spread.

What appeared in front of his eyes seemed to be a corridor of starlight, and on both sides of the corridor, there seemed to be countless balls of light appearing, and then popping out like bubbles.

Zhou Yuan stared at those bubble-like balls of light, and could faintly see that there seemed to be something inside them.

"The things in these light balls should be exercises, source techniques, source patterns, and source soldiers..."Zhou Yuan thought thoughtfully, but there was no way to spy inside the light ball, so there was no way to know the grade of the things inside.

All of this seems to depend on their luck.

"No wonder it's casual. Zhou Yuan smiled bitterly, inside these balls of light, there may even be nothing, as long as one is grabbed, it will be sent out of the Ancient Scripture Building.

Zhou Yuan looked at those balls of light and hesitated for a while, but he didn't do it immediately, but took a step, avoiding those floating balls of light, and walked forward.

He was going to make an observation first.

He didn't stop, his gaze swept carefully, and at the same time, the spiritual perception also spread, trying to peek inside the ball of light.

However, these methods are ineffective, and the ball of light seems to be able to shield the perception of the divine soul, so even with Zhou Yuan's mid-realm divine soul, it is all in vain.

"Is it really just one that can be grabbed at random?" Zhou Yuan frowned, in that case, the randomness would be too great, and it was not easy for this ancient scripture building to be able to enter once, if it was so casual, it would really be a waste of opportunity.

He pondered for a moment, and suddenly his heart moved.

"You can't snoop on it in ordinary ways, I don't know... How about the Barrier Breaker?"

Thinking of it, Zhou Yuan's heart moved, and he saw that there was an ancient holy pattern spinning in the depths of his pupils, and with the operation of the holy pattern, he looked at the light balls floating back and forth again, and then he was happy to see that inside the light balls, there seemed to be an uncertain light emerging.

Although he still couldn't see the things in it clearly, he was able to judge the level of things inside the ball from the strength of that light.

Looking at this appearance, it is obvious that the better the grade, the stronger the light.

And inside some balls of light, they are empty, and no light appears, which should be because they are originally empty, and if anyone catches this ball of light, they must only come out empty-handed.

Zhou Yuan's face was filled with joy, and with the help of the Barrier-Breaking Holy Pattern, he didn't have to touch the elephant blindly, it was all up to his imagination.

So, he slowed down his pace and walked forward slowly, the holy pattern circulating in the depths of his pupils, sweeping over the balls of light.

In this way, the time of half a pillar of incense passed, and Zhou Yuan came all the way and found four balls of light with the strongest internal light, according to his guess, inside these four balls of light, they must all be treasures at the level of Tianyuan Technique.

Zhou Yuan couldn't help licking his lips, his eyes were blazing, Tianyuan Technique, even in the Cangxuan Sect, this is an extremely rare thing, if there is no great merit, it is absolutely impossible for ordinary disciples to get it.

Even he, now, he had only just cultivated a low-grade Heavenly Source Technique.

Any Heavenly Source Technique, which can be cultivated, can be described as a huge improvement in one's own combat effectiveness.

"I can only choose one. Zhou Yuan hesitated for a moment, and then gritted his teeth, and was about to reach out and grab a ball of light.

Airplanes!

However, at the moment when he was about to catch it, Zhou Yuan's palm suddenly froze, because he noticed a slight fluctuation coming out of the Qiankun bag.

Zhou Yuan was stunned, and as soon as he shook his palm, he saw a jade light appear.

In the palm of his hand, an ancient jade plaque slowly rose, and among the jade plaques, an indescribable aura was emanated.

This jade plaque is the seal letter given to him by the ancestor of Cangxuan in the land of holy miracles.

And the previous subtle fluctuations came from this seal.

"What's going on?" Zhou Yuan looked at the jade plate in his hand that shook slightly, this was the first time this had happened since this seal letter arrived in his hand.

Buzzing!

And when Zhou Yuan was shocked, the balls of light around him seemed to be aware of this breath, and then they burrowed into the wall of light with a bang and disappeared.

Even the four balls of light selected by Zhou Yuan disappeared.

Zhou Yuan was immediately anxious when he saw this, as soon as this seal letter came out, why did he scare these balls of light away, so how could he take the treasure?

"It's too bad!" But it was useless for him to be anxious, so he could only watch the ball of light disappear, and he wanted to cry without tears.

While Zhou Yuan was speechless, the seal letter in his hand slowly floated up, and then headed forward.

Zhou Yuan was stunned, hesitated for a moment, and then quickly followed, this used to be the place where Cangxuan Ancestor cultivated, and now he came in with the ancestor's seal, he won't suffer a loss after all, right?

After following the Yinxin Jade Plate, Zhou Yuan walked all the way forward, and after a long time, his footsteps gradually stopped, because the starlight corridor in front of him had reached the end.

However, the seal letter still didn't stop, slowly moving forward, and then Zhou Yuan was shocked to see that as the seal letter approached, the end of the starlight corridor was slowly torn apart.

The jade plate flashed, as if urging Zhou Yuan to follow.

Zhou Yuan hesitated for a moment, and finally gritted his teeth, took a quick step, and stepped into the starlight gap with one foot.

As he stepped in, the scene in front of Zhou Yuan's eyes suddenly changed, and he found himself standing in an ancient house, which was quite simple and exuded the breath of time.

The jade plaque fell in front of Zhou Yuan and was carefully put away by him.

"Here, could it be the place where the ancestor once cultivated?" Zhou Yuan looked at the futon on the stone bed in front of him and muttered to himself.

He looked around for a moment, and finally stopped on the table in front of the stone bed, because he saw that there seemed to be four jade slips lying quietly on the table.

Zhou Yuan walked up curiously, picked up a jade slip casually, sensed it slightly, and then his pupils shrank sharply.

"It turned out to be a mid-grade Heavenly Source Technique..."

In the Cangxuan Sect, the Heavenly Source Technique that the disciples can obtain is generally at the level of the lower-grade Heavenly Source Technique, and if you want to obtain the middle-grade Heavenly Source Technique, the difficulty is not known to be many times higher than the former.

And Zhou Yuan didn't expect that he would pick up a jade slip casually in this room, and what was recorded was a medium-grade Tianyuan technique.

Zhou Yuan was shocked in his heart, and picked up the other three and looked at them, and found that two of them were medium-grade Tianyuan Techniques, and looking at their appearance, even in the medium-grade ones, they were not of low grade.

As for the last one, it was the most shocking thing for Zhou Yuan, because it was a volume of seven-rank exercises, which could cultivate seven-rank source qi!

These jade slips, placed at random, don't seem to be very valued by Cangxuan Ancestor at the beginning.

However, this is also for Cangxuan Ancestor, but for Zhou Yuan, it is all dreamed of, and now he is even greedily thinking about whether he can take it all away in one go.

But in the end, he still resisted his greed, after all, the ancient scripture building has rules, if it is discovered at that time, maybe it will be a bamboo basket for water.

"Then just pick a medium-grade Heavenly Source Technique. Zhou Yuan hesitated for a long time, and finally gritted his teeth and decided, although the seven-grade exercise was better, it had no effect on him.

So, he stretched out his hand, grabbed a jade slip directly in his hand, and then turned away.

But the moment he turned around, out of the corner of his eye, seemed to catch a glimpse of greenery, and then his footsteps paused, and when he looked down, he saw a green plant like a small green pine in the corner of the stone bed.

This thing is inconspicuous, and even if you see it, it is easy to be overlooked, after all, there is nothing strange about a green plant.

But at this time, Zhou Yuan's pupils had holy patterns circulating, so when he saw the green plant, he was stunned, because he could clearly see that on the trunk of the green plant, there seemed to be ancient traces, exuding a strange charm...

So he walked back quickly, put down the jade slip, and carefully picked up the green plant.

In the pupils of his eyes, the holy lines flowed, and the ancient traces on the torso of the green plants seemed to be beginning to converge, reflecting in his pupils.

An ancient message surged through his mind.

"Immortal body, Taiyi green wood marks. ”
