The five ancestors appeared one after another, and the old man naturally followed, and today compared to last time, they were more restrained and even respectful.

When Zi Chen entered the Ancient Battlefield, it was only in the Imperial Sky Period, and he naturally couldn't kill the ancient beasts that surpassed the Dan Yuan, and he had this level of ancient beast essence blood, which could only be killed by the old man.

In order to clearly understand the old man's combat power, after the five of them went back, they also found Shangguan Bingxi again and carefully inquired about the situation at that time.

Shangguan Bingxi did not hide it, everything was 'told truthfully'.

But the news he got from Shangguan Bingxi was completely different from Zi Chen's. Shangguan Bingxi clearly informed that there were eight people of the same level who were fighting with the old man at that time, and the other party was desperately killing two.

Zuihou had to stop the battle because of the change in the rules of heaven and earth.

Although Shangguan Bingxi threatened that the old man was also seriously injured at that time, this still did not prevent their trembling hearts.

So when they came today, they looked restrained and respectful. And they also knew that Zi Chen had more than just a hundred drops of essence blood on his body, and they all hoped to exchange for more through normal means.

"A few seniors brought the materials so quickly?" Zi Chen looked surprised.

"After we went back, we searched through all the treasure troves, and the amount of materials that obviously belonged to the formation was not large, so we could find it quickly. ”

"Yes, we just found a batch of them, and we exchanged them for some essence blood first, and as for other materials, they are also being prepared. ”

Several people spoke.

Zi Chen nodded, understanding what they meant. Obviously, they were afraid that the other party would exchange their essence and blood early, so they each brought a batch to exchange it first. Moreover, they have such materials in their treasure house, and it is also because there are no outstanding array masters in the family, so once they obtain these materials, they will all be placed.

"Little friend Zichen, these are our list of materials, how much essence blood can you exchange for when you look at it?" Several people took out the list one after another.

These are all the materials required by Zi Chen, among which the quantity and weight are clearly written, in addition, in all the materials of Zuihou, the price of exchange for yuan stone is clearly marked.

These formation materials, Zi Chen is all useful, and they are very useful, so naturally they all have to be replaced. But when it came to exchanging, it was difficult, he didn't know how many high-grade yuan stones should be exchanged for a drop of ancient beast essence blood?

"A few seniors, in the history of Chaos City, have there been any auctions of ancient beast essence blood?" Zi Chen asked.

Several people looked at each other and shook their heads. No one can afford to have too many of them, and no one can put them up for auction. Moreover, among the major auction houses, except for a Buddhist scripture, nothing has been auctioned on the ancient battlefield.

"Then do the seniors know how much this drop of essence blood is worth?" Zi Chen asked again.

When several people heard about it, they wanted to say that this thing was priceless, and it would not be sold for any yuan stone, and it was a real priceless thing. But as buyers, they naturally wouldn't say that, and one by one they pretended to be stupid, just asking, "How much is Xiaoyou worth?"

Zi Chen suddenly felt disdainful, I want to know the price, I still need to ask you?

But looking at the five people's eyes, noses, noses, and hearts, it was obvious that they didn't plan to make a price, so after Zichen hesitated for a moment, he tried to say a price, "How about 50 million?"

Fifty million, naturally fifty million top-grade yuan stones. In other words, this drop of ancient beast essence blood is equivalent to twelve treasure pills, which is equivalent to Zi Chen's sky-high cost of hiring five hundred pills for a year.

This is an extremely frightening number.

Zi Chen thought that they would hesitate when they heard it, but who knew that they were expressionless, just nodded and said, "It's good that Xiaoyou feels good!"

This made Zi Chen a little embarrassed, he originally expected them to bargain, and he also had the heart to lower it for them. But people didn't say it, and Zichen couldn't continue to speak, so he exchanged it at the price of 50 million per drop.

It's just that Zi Chen didn't know that after the four people on the other side heard this, they were also greatly relieved. At the same time, he secretly despised Zichen in his heart, he was worthy of being from a barbarian land, and he had never seen any big world. You know, their previous minimum estimate was also more than 100 million high-grade yuan stones.

Because this thing is not measured by yuan stones at all, even if it is 100 million yuan stones, they are willing to pay. And they believe that if they sell these essence blood in other regions with strong backgrounds, the value of this thing will only be higher.

Moreover, Zi Chen did not open his mouth to ask for Yuan Liquid, but only asked for Yuan Stone, which also made them extremely happy. Because the strength has reached a level, the Yuan Stone is also useless, and only the Yuan Liquid has always been useful.

But Zi Chen is a barbarian, and the most expensive thing to buy in his life is Bao Dan, and a drop of essence blood is equivalent to more than a dozen Bao Dan, and he is content in his heart.

So, they thought they could only exchange a few drops of essence blood, but this time they also exchanged half more.

Among them, only the Shangguan family exchanged nine drops, and several other families also exchanged eight drops. The things they brought were all about the same, and the reason why the Shangguan family had a drop more was because the ancestor of the Shangguan family mentioned Shangguan Yue'er.

And he invited Zi Chen to Shangguan's house as a guest, saying that Yue'er hadn't seen you for a long time, and he was always talking about you.

This move was a great gesture of goodwill, so Zi Chen gave the other party one more drop, and this move was also envious of the four people next to him.

Immediately, Zi Chen took out the essence blood, and the terrifying ferocity contained in it also made the eyes of the five people eager.

With this breath alone, they knew that the essence blood was not adulterated, and it was indeed the true essence blood in the body of an ancient beast that surpassed the level of Dan Yuan, not the essence blood that was refined from ordinary blood.

After obtaining the essence blood, they seemed to be desperate to refine, and they didn't want to stay longer for even a moment, so they took their leave and left.

Of course, Zi Chen didn't want them to stay long, and he also had a lot of things to do. After sending the five people away, he called the people, took the five spirit rings, and walked towards the location where the pavilion was built.

It's just that when they came again, Zi Chen and the others saw that there were many demon beasts below, and they were dozens of miles away, and they also saw the figure of a human being.

The aura of heaven and earth here is extremely strong, and these demon beasts have been cultivating here before. As for those humans, they are some miners from the True Yuan Realm, who sense that there is something here and want to mine it.

"Tell Yukong to let them leave, and they won't bring anyone here again in the future!" said lightly again.

These miners are naturally also Zichen's people, so Wang Shan went to the leader Yukong to give a lecture.

"As for these demon beasts, let them leave first, and after we open the pavilion, they can come back if they want. Zi Chen thought about it, and finally left them a way out.

The monk is the best at showing off like this, so he went to warn those demon beasts, and there are even sky demon beasts here, which is really surprising.

This area covers an area of more than 100 miles, with dozens of spiritual veins, mountain ranges are continuous, and almost every mountain peak has a spiritual vein. The next lock spirit is Mo Lao's business.

He wants to use these formation materials to lock the spiritual veins below, this is a real jishu job, and no one in the group can interfere except for Lu Peng.

Moreover, Mo Lao deliberately mentioned Lu Peng and taught him the way of the formation, mainly with guidance and hands-on supplementation. Therefore, this huge project has to be completed by Lu Peng.

"There is not much difference between the Soul Locking Array and the Divine Forbidden Soul Locking Array, one is to block the soul thoughts, and the other is to lock the spiritual veins. You first have to rely on your perception to find the root of the spiritual vein, and the lock spirit is to lock the root. "Mo Lao taught.

Lu Peng kept nodding, and then released his spiritual thoughts to sense carefully.

Then he walked slowly from the top of the mountain to the bottom of the mountain, and stopped at an inconspicuous puddle.

"Mo Lao, I feel that the root of the spiritual vein is under this puddle. Lu Peng opened his eyes and said, he had always closed his eyes before.

"Yes, the perception is getting sharper and sharper, and the next thing is to lock the spiritual veins here. Mo Lao nodded.

Lu Peng took out a lot of materials from the spirit ring, and then began to place the materials according to the spirit locking array. During this period, he had to perceive the size of the spiritual veins and the range of the formation. After a busy hour, it wasn't until Lu Peng, who was sweating profusely, that he was done.

Just as he was waiting to accept Mo Lao's praise, who knew that Mo Lao actually shook his head and said, "The Spirit Locking Technique only allows you to lock the spirit vein, but it doesn't let you lock it." It is similar to the Divine Forbidden Soul Lock, but it is two completely different techniques. The Divine Forbidden Soul Lock is locked, and it will be released all at once when it is used. But the lock spirit is only locked and not locked, there must be room for movement, and this is a vast spiritual vein not a human soul, once you lock it, when the spiritual vein expands to the limit and breaks through the lock spirit array, it will bring destruction. ”

When Lu Peng heard this, cold sweat appeared on his face instantly, once the spiritual vein exploded, the power was really unimaginable. If you build a pavilion with this formation, then before other shili can attack, this place will turn into nothingness after the formation is broken.

So Lu Peng came again, but Mo Lao didn't tell him what to do, just kept mentioning points and letting him understand on his own.

After repeating this repeatedly, it took Lu Peng two days to successfully lock the branch of the smallest spirit vein.

Wiping the sweat from his forehead, Lu Peng said, "Old Mo, will this be too slow?"

Mo Lao shook his head and said, "It's okay!"

"But at this rate, it will take at least a few years to lock all the spiritual veins. Lu Peng said.

"Practice makes perfect!" Mo Lao smiled.

Just when Mo Lao took Lu Peng to lock the spirit, Zi Chen and the others were not idle, they traveled all over the radius of a hundred miles, until they recorded all the mountains, stones, grasses and trees here in their minds, and according to their own imagination to build something on the mountain peaks, they also made corresponding marks for each mountain peak.

Some of the marks run halfway up the mountain, meaning that they are flattened and only half of them are left. And some are just at the top of the peak, which is meant to be simply modified at the top of the peak.

And during this period, Zichen and others also kept communicating, of course, the loudest voices in the exchange were Wang Shan and the monk.

"This is the main pavilion of the future!"

Wang Qiong pointed to the thousand-meter-high mountain peak in front of him and said.

This is the highest mountain within a radius of 100 miles, and there are some small peaks on all sides, as if it is sanitized. And at the beginning, Mo Lao also said that under this main peak, there is a huge spiritual vein.
