Early the next morning, Su Chen and Wang Tiancheng went out.

However, Su Chen went to the cultivation tower, and Wang Tiancheng lost the martial arts pavilion, and the two did not go the same way, so they separated after leaving the mansion.

Walking on the way to the cultivation tower, Su Chen met many people, but when those people saw Su Chen, they all hurriedly avoided from afar, looking very scared.

In this regard, Su Chen shook his head, he naturally knew that these people were like this after seeing the decisive battle between him and Xu Tianhe yesterday.

But it's good that some people in the province keep coming to harass themselves.

After about half an hour, Su Chen finally came to the cultivation tower.

The cultivation tower seems to be made of special materials, with a total of nine floors, forty or fifty meters high, and the area is still very large.

According to what Cui Xueping said yesterday, the higher the position of cultivation, the faster the speed of cultivation.

Of course, cultivating in the cultivation tower naturally comes at a price, and if the cultivation tower is compared to a hotel in the hot summer, then the contribution value is money.

You are only eligible to move in if you have paid the bill.

According to Cui Xueping, just cultivating on the first floor of the cultivation tower will cost fifty contribution points, and you can only stay in it for twelve hours at most.

In other words, if you want to stay at the first level of cultivation all day, you have to spend at least one hundred contribution points.

Su Chen only has a total of two hundred contribution points now, and at most, he can only cultivate on the first floor of the cultivation tower for one day.

As for the second layer, the minimum standard is one hundred contribution points, and if you want to cultivate in it for one day, you need a full two hundred contribution points.

In the upper three layers, Su Chen's current contribution value is not even qualified to enter.

However, Su Chen came over this time, mainly to test how much the cultivation tower can increase the cultivation speed, as for the contribution value, it is a big deal to go to the Yunling Mountain Range to hunt demon beasts and exchange them.

While thinking about it, Su Chen had already walked into the cultivation tower.

The space inside is very spacious, and you can feel that the aura here is indeed a little richer than the outside world, but it is still a little unrealistic to say how much cultivation speed can be improved.

Su Chen looked at it and saw someone queuing up at a table not far away.

Sitting at the table was a man in his thirties, and after he took the identity card of the person in line, he checked it and gave him a wooden card.

Because Su Chen had already asked Cui Xueping about the cultivation tower yesterday, he knew that what could really increase the cultivation speed in the cultivation tower was a separate stone room.

Before entering the stone chamber, you have to use the contribution points to exchange the number plate of the stone chamber with the person in charge of the cultivation tower.

It seems that the man in his thirties is the person in charge of the first floor.

Thinking of this, Su Chen no longer hesitated, walked to the back of the line and began to line up.

In about five minutes, it was Su Chen's turn, and he handed his identity jade card to the man in front of the table.

After the man took it, he urged his true qi, and Su Chen's information appeared from the identity jade plate, and his contribution value was displayed behind his name.

"Su Chen, how long are you going to stay in the cultivation room. After checking the identity of the jade pendant, the man asked lightly.

"Twelve hours. Su Chen replied.

The man didn't say anything more, deducted Su Chen's fifty contribution points, and then took out a wooden card and handed it to Su Chen: "305 stone room, you must come out on time after twelve hours." ”

"I understand. Su Chen nodded, took the wooden card, and turned to leave.

Then, after turning around on the first floor, Su Chen finally found the No. 302 stone room, opened the door of the stone room with a wooden sign, and walked directly in.

The space inside the stone chamber is not large, and the layout is very simple, except for the futon in the middle, there is nothing else.

It's just that as soon as Su Chen walked in, the whole person was stunned.

The aura in the stone chamber is too rich, nearly sixty percent more than the outside world!

You must know that the spiritual aura inside the spirit ruins is already very strong, plus this sixty percent, it is not an exaggeration to say that it is a cultivator's paradise!

Cultivating here, it is estimated that it can already be comparable to the cultivation speed of using spirit stones.

Moreover, this is only the first layer of the cultivation tower, and the aura of the second and third layers is not even more terrifying?

After a long while, Su Chen came back to his senses from the shock, but he didn't sit down to cultivate, but showed a thoughtful look.

For no reason, how could there be such an extra aura in the cultivation tower, so there must be some subtlety here, which can gather the aura of heaven and earth faster!

Except for some real cave heaven blessed land, Su Chen felt that there was only one possibility, and that was the formation!

Only by using the formation can the aura of other places be gathered here and become a treasure land for cultivation.

Su Chen was preparing to study the formation, so he was naturally a little curious about what the formation in the spirit ruins was like, so he looked around the stone room to find the location of the weapon formation.

According to the knowledge imparted to him by Gong Yuechan, the formation requires an energy carrier, unless the strength is strong to a certain point, and the true qi in the body can exist in the void for a long time, so that the void condensation array can be carried out.

Even if this was the Spirit Ruins Academy, Su Chen didn't think that such a powerful array mage would exist.

Therefore, there will definitely be some formation carriers in the stone chamber, such as spirit stones and the like.

After careful observation, after a while, Su Chen saw that on one of the walls of the stone room, there were several similar stone blocks of different colors inlaid with them.

Those stones were carved with some talismans, and it was these talismans that were combined to form a formation of gathering spirits!

"It's a beast core!"

Su Chen showed a shocked look, because he found that those stones were the beast cores in the demon beast's body!

However, he had obviously tried, and because the energy in the beast core was too violent, it could not be used to depict the formation at all.

Could it be that Lingxu Academy really has such a powerful formation powerhouse, who can use the beast core to carve the formation?

Su Chen's brows furrowed tightly, if this was really the case, it could only mean that the last experiment did not mean that the beast core could not be used to depict the formation, but that his own strength was not enough.

After thinking for a while, Su Chen stretched out his hand and placed it on top of the beast core embedded in the wall, wanting to see how others dealt with the violent energy inside.

"Hey, something is wrong, the power in these beast cores is so weak. As soon as his palm was placed on the beast core, Su Chen showed a look of surprise and blurted out.

He found that the energy in these beast cores was much weaker than that in normal beast cores, and he couldn't feel the violent energy applied in the beast cores at all!

Such a situation made Su Chen ponder again, and after a while, he had a flash of inspiration and finally figured it out.

"I know, the normal beast core really can't be used to depict the formation, but it can be used in some ways to refine the violent energy in the beast core, so that although the energy in the beast core will become very weak, it can barely be used as the carrier of the formation!"

"However, this also has a disadvantage, that is, the residual energy in the beast core is too small, it can't last too long, and it needs to be replaced regularly, which is probably why the Spirit Ruins Academy lets members exchange the demon beast core for contribution points. ”

"After all, only with enough beast cores can the formation be maintained!"

Su Chen's eyes flickered again and again, if he guessed correctly, wouldn't he be able to use the beast core to carve the formation in the future?

Thinking of this, Su Chen couldn't wait to try it, but he didn't have the beast core on hand, and if he wanted to experiment, he had to go to the Yunling Mountain Range once.

It's just that he has already spent fifty contribution points today, so naturally he can't waste it, so it's better to cultivate first, and wait for tomorrow to talk about the matter of hunting demon beasts.

Taking a deep breath, Su Chen didn't think much about it anymore and sat down cross-legged to cultivate.

With the operation of the exercises, the aura in the stone chamber frantically surged towards Su Chen's body, and under this rich aura, Su Chen's cultivation also increased clearly.

Twelve hours later.

Su Chen opened his eyes, let out a long breath of turbidity, and then his face showed joy.

The speed of cultivation in the stone chamber was completely comparable to the state of using spirit stones, and it only took twelve hours for him to reach the middle stage of the sixfold spirit base!

If he followed his normal cultivation, he would need at least a week or so.

"It seems that the benefits of the Spirit Gathering Array to cultivators are not ordinarily great, if I have been cultivating in such an environment, in less than a month, I will almost be able to break through to the seventh level of the Spirit Foundation. Su Chen muttered to himself, a deep color flashing in his eyes.
