Immortal cultivation starts with copying.

Before leaving, Chen Yunhao and Zhang Qing made a deal.

Chen Yunhao bought all the monster corpses that Zhang Qing had not sold yet.

In Zhenhuang City, Zhang Qing was the leader of a team, so the entire team's harvest depended on him, which was more than one hundred and twenty corpses of monsters.

In recent months, many monks have fled to Wanling City, causing the price of monsters to drop slightly.

Therefore, Chen Yunhao never sold out the monster corpses in his hands.

Originally, he only had a dozen or so, but this number was not enough to do anything.

But with the corpses of more than a hundred monsters killed by Zhang Qing, he might be able to exchange them for a monster pill when he returns to Yuxian City in the future.

Since both parties were acquaintances, Chen Yunhao was not short of those spirit stones, so he gave Zhang Qing a good price.

Zhang Qing's life-saving magic weapon was damaged and he was short of money, so both parties were happy.

After the two parted ways, Chen Yunhao returned to the market to do some shopping, and then asked the shop that had helped him make the elixir last time to entrust him with the task.

After six or seven days, Chen Yunhao once again entered a state of seclusion and cultivation.

It may also be because he suffered a loss in the wilderness, Chen Yunhao always felt uneasy staying in Wanling City.

Therefore, he had to build his foundation as soon as possible. Only after building his foundation would he have some ability to protect himself and be able to cross a million miles and return to the Yuxian City he was familiar with.

This retreat lasted for a year and a half, during which Chen Yunhao came out two or three times to buy some elixirs and tiger soul pills.

During the year and a half that he was in seclusion, which should be about half a year ago, three or four human cultivators who had reached the stage of Divine Transformation gathered in Wanling City.

I don’t know what these powerful people on the Northern Yuan Continent were discussing, but they all left after one day, and it seemed that they were heading towards the wilderness.

More than half a month after several Jindan cultivators left, a human cultivator brought back news.

It is said that the monster was spotted one or two thousand miles away from Wanling City.

But there are not just one or two, but hundreds or even thousands of them. They are not just in one spot, but are everywhere along the border of the wilderness.

So it didn't take long before a piece of news spread throughout Wanling City.

That is, the monsters are no longer confined to the wild areas, but are expanding into the human territory. This is not a good thing.

This means that a war between humans and demons is about to take place, and the demons have unilaterally broken the pattern on the Beiyuan Continent that has not changed for tens of thousands of years.

The human race will definitely not retreat. Losing territory means losing resources. Without resources, how can they cultivate immortality and achieve longevity?

Chen Yunhao didn't know all of this and hadn't come out for more than half a year, but fortunately his cultivation had reached a critical juncture.

After a year and a half of secluded practice, I have achieved the Great Perfection of Qi Refining, which is really perfect, but I have reached a bottleneck.

The bottleneck is for most ordinary cultivators, but it is not difficult for a cultivator like Chen Yunhao who has good spiritual roots and aptitude.

But before making a breakthrough, some necessary preparations must be made.

For example, the foundation-building pills have already been prepared, and there are more than double portions.

The Peiyuan Pill, which is used to stabilize cultivation after building the foundation, has also been purchased long ago.

In order to prevent any accidents from happening during the foundation-building process, he had purchased a highly defensive formation at a high price half a year ago.

This formation not only has strong defensive capabilities, but can also conceal all fluctuations of spiritual light and precious energy within the formation, making it perfect for use in conjunction with the Baji Locking Gate Formation.

Everything is ready, all we need is the east wind.

Chen Yunhao was not unfamiliar with the foundation-building process. After all, he was from a sect.

Not only were there records of this in the sect's scriptures, his master Zui Dao Ren had also told him about it, and even his two senior brothers had given him some pointers on what to pay attention to.

The true energy in the body is surging and flowing through the meridians, and it feels like the meridians are almost reaching their limit.

But Chen Yunhao knew that this was far from enough. Next, he had to compress the true energy in his meridians as much as possible.

It is not yet time to take the Foundation Establishment Pill. You must continue to take the Small Yuan Pei Pill to increase the true energy in your body.

When the true energy in his meridians has been compressed to the point where he can hardly control it, it is time to take the Foundation Establishment Pill.

The effect of the Foundation Establishment Pill is more of an auxiliary function, and it does not force a cultivator's cultivation from the Qi Refining Stage to the Foundation Establishment Stage.

The Foundation Establishment Pill has three auxiliary functions. The first is that it can protect the cultivator's meridians so that they are not torn apart by the exploding and surging true qi.

Secondly, it can assist cultivators in compressing the true Qi in their bodies, helping them transform the true Qi into true essence.

The third one is very crucial. The foundation-building pill has a purifying effect and can purify the cultivator's true qi.

The third point is very important, but it is almost useless for cultivators with natural spiritual roots.

Because the true qi in the body of a cultivator with natural spiritual roots has only one attribute and does not need to be purified at all, there is almost no bottleneck for cultivators with natural spiritual roots when breaking through the foundation.

Chen Yunhao has mutated dual spiritual roots. So far, the true energy in his body tends to be fire-attributed, which is also a single attribute. The third one is not very useful to him.

So, which cultivators would be most useful for the third rule? Naturally, it would be cultivators with three, four, and five spiritual roots.

The properties of the true qi in the bodies of cultivators below the third spiritual root are more complex, and it is more difficult to purify it.

This is also the reason why cultivators with poor spiritual roots need to prepare a few more foundation-building pills. Sometimes they need three or five foundation-building pills to advance to the foundation-building stage.

The purpose of this purification is to purify the chaotic true qi into one main attribute, with other attributes as auxiliary.

In a word, it’s not that one cannot cultivate immortality with spiritual roots of the five attributes, but the price to pay is too high.

Others can reach the destination by taking one path, but cultivators with five spiritual roots have to take five paths to reach the destination.

The effort and resources invested in this process are four or five times that of cultivators with natural spiritual roots, so most cultivators with five spiritual roots end up living a mediocre life and stop at the stage of refining Qi and building the foundation.

As far as Chen Yunhao knows, there is no set of exercises in the entire Beiyuan Continent that is specially created for cultivators with five spiritual roots.

It's so difficult to cultivate and improve the five attributes of the five spiritual roots at the same time! It's absolutely against the will of heaven!

Although the Five Elements Sect is called the Five Elements, there is no record of any such exercises.

The origin of the sect is the spiritual roots of the five founders of the sect, which are the spiritual roots of the five attributes of gold, wood, water, fire and earth, so it is simply called the Five Elements Sect.

It seemed that the true energy had been compressed to the extreme and was showing signs of running wild.

Chen Yunhao hurriedly took out a foundation-building pill and swallowed it in one gulp.

The foundation-building pill was touched by the golden essence and jade liquid, and it melted in the mouth, went down the throat, and immediately spread to the internal organs, muscles, skin membranes, and blood vessels.

Suddenly, Chen Yunhao felt as if a layer of invisible energy was attached to his aching meridians, and the pain disappeared immediately.

And the true energy that he had compressed with all his might seemed to become a little docile.
