According to the ratio of ten times of cultivation, the actual time will not be twenty days, and the core area will have to consume the resources of an entire spiritual vein.

The spiritual vein, if it weren't for the fact that Li Yiren put these five in the core area, Cao Fan would not have even seen it before.

Those who can possess spiritual veins are generally fourth-level sects, and even if they have third-level sects, they can't keep them.

More than eighty years ago, the Cangyun Sect had two spiritual veins, and after the sect was breached, it was directly withdrawn by the Qingtian Sect.

Although the current Cangyun Sect has a large array of protectors, the way to replenish the aura still relies on manually filling the spirit stone warehouse.

If a strong enemy is attacking, the speed at which the large array consumes spirit stones is too fast, there will be no time to replenish the spirit stones, so that the defense of the large array will be broken through.

Among the five spiritual veins, Cao Fan was ready to use one to lay at the core of the Cangyun Sect's Sect Protector Array.

With the supply of spiritual veins, the protection ability of the Cangyun Sect's Great Sect Protection Array will be raised to a new level.

In other words, Cao Fan was fully calculated, and there were only four spiritual veins left to control.

But the problem is that to maintain the operation of the core area of the Taishang Nine Realms, at least three spiritual veins are required, so he can only use one more spiritual vein at most to use the time law of the core area.

And after this spiritual vein was consumed, it only allowed him to earn an extra half a year of time dividends.

The effect of the spiritual vein is very large, and it is only used to earn 180 days of cultivation time, which is simply a blood loss.

Even the Li Yiren, who had five spiritual veins in his hands, gave up using this law of time after cultivating in the core area for a few days.

The cost is simply too high.

Cao Fan thought about it for a moment and resolutely activated the law of time.

He needed the veins so much, but he needed time even more.

If he didn't rush to greatly improve his strength before the Yuanying powerhouse of the Qingtian Sect attacked, Cao Fan would not have much confidence that he would be able to protect the sect with the existing Sect Protector Array.

Of course, it's a last resort. He would choose to let all the disciples enter the Taishang Ninefold Realm, and then teleport back to Earth through the Primordial Teleportation Crystal.

Cao Fan can choose to give his defeated enemies a way out and let them enter his own small world. But he was very reluctant to let his acquaintances and friends stay in it for long.

Because he is the master here, everyone enters here, and there is no longer any ** in front of Cao Fan.

Their every move, what they thought in their hearts, would all be exposed in front of Cao Fan.

Even, under the influence of the rules of the world, they will also subtly enhance their loyalty to Cao Fan.

In this way, friends are no longer friends, and relatives are no longer relatives.

This is not the result that Cao Fan wants.

One day, when all the people around you regard you as a god, all that will be left for you is endless loneliness.

Maybe to a certain level of cultivation, Cao Fan can handle all this calmly.

But growing up on Earth, he is still unable to adapt himself to such a transition.

An ordinary spiritual vein was about five miles long, and as soon as the time rule was activated, Cao Fan, as the master of the world, could clearly feel the rapidly depleting spiritual energy on the spiritual vein.

However, he couldn't control it so much, and directly operated the Heavenly Fortune Creation Technique and began to cultivate wildly.

Ever since he began to cultivate the Heavenly Fortune Creation Technique, Cao Fan had been spending almost all his time in constant busyness, and he didn't have much time to sit down and cultivate to his heart's content for a while.

Now, he is in his own world, and with a time bonus of one as ten, he can finally improve his cultivation happily.

Cao Fan's current cultivation potential value is 225 points, which is not even half of that of his precious apprentice Yu Xiaochuan.

In order for him to break through to the sixth level of Qi cultivation, what he needed was 260 Fa cultivation potential points.

The most common way for a monk to increase his cultivation potential is to spend a lot of time filling it in.

The longer the cultivation time, the more the Fa cultivation potential will increase.

However, due to the constraints of qualifications, some monks have to spend several years of penance before they can barely increase their cultivation potential by one or two points.

The closer you get to breaking through the realm, the more difficult it is to increase your cultivation potential.

Some monks are unable to improve their cultivation potential even after exhausting their entire lives.

In addition to consuming time, monks can also use high-quality resources to increase their cultivation potential.

High-quality elixirs and aura atmospheres all have the opportunity to increase the monk's cultivation potential.

Of course, this is only limited to the first time you take a high-quality pill. If you take the same pill too much, the effect will get worse and worse.

Good exercises can also help monks quickly increase their cultivation potential, and the more powerful the exercises, the more significant the improvement effect.

With Cao Fan's help, Yu Xiaochuan was able to increase his four-point Fa cultivation potential in less than an hour, and a large part of the reason was that the exercises he cultivated were too good.

You must know that the higher the potential value of the Fa cultivation, the more difficult it will be to improve later.

Ordinary monks want to increase the potential value of Dharma cultivation from 476 points to 480 points, and those who have good qualifications and are not bad in the practice are also required to practice penance for one or two decades. If the exercises are poor, I am afraid that they will not be able to achieve it for the rest of their lives.

Cao Fan possessed a pure fire spirit root, which itself had a fast cultivation speed. His current spiritual root qualification has reached level 20, and it has also greatly improved his cultivation efficiency.

Being in the midst of the five spiritual veins, the aura atmosphere is definitely extremely high-quality.

And what he cultivated was also a super-high-level top-level exercise, the Heavenly Fortune Creation Technique.

In addition, he also had many high-quality cultivation pills that Xin Qianyue had given him to take.

These factors combined, when Cao Fan was cultivating with all his might, his cultivation was equally amazing.

In the first month, Cao Fan's Fa cultivation potential increased by an average of three points per day. After a month, he had broken through to the peak of the sixth layer of Qi training.

In the next two months, Cao Fan's cultivation potential increased by an average of two points per day, and his cultivation continued to rise, reaching the peak of the eighth layer of Qi cultivation.

At this time, the gap between him and Yu Xiaochuan's Fa cultivation potential value was not that big.

In the last three months, Cao Fan's average daily increase in Fa cultivation potential slowed down, and he was not even a little less than that.

Especially when he finally hit 520 points from 519, it took him a full seven days.

520 points is the threshold of the Dharma cultivation potential required to cultivate the Heavenly Fortune Creation Technique to break through to the first level of foundation building.

This means that Cao Fan, who is already cultivating Qi and cultivating the Great Perfection, can start to impact the Foundation Building Realm.

Practicing ordinary exercises, monks can increase their combat power by 20 points when they break through to the late stage of Qi training.

When Cao Fan stepped into the late stage of Qi training, he increased his combat power by a full 30 points.

The ascension of each realm of the Heavenly Fortune Creation Technique requires a much higher potential value of Dharma cultivation than ordinary exercises.

Yu Xiaochuan's 480 points of Dharma cultivation potential for the Great Perfection of Qi cultivation rested on ordinary monks, which could meet the needs of the eighth layer of foundation building.

When breaking through the realm, it is much more harsh than ordinary exercises, and the benefits will naturally be greater.

Because of this, throughout the ages, good exercises have always caused frantic competition among monks.

Others can build a foundation in the Taishang Nine Realms, but Cao Fan cannot.

As the master here, if Cao Fan builds a foundation here, the biggest drawback is that he can't get the real realm breaking experience.

Because the rules of the world cannot allow a master to fail to build a foundation.

In this case, his foundation will not be solid, and there will be endless troubles.

Cao Fan had been in retreat for six months in the Taishang Nine Realms, and nearly twenty days had passed outside, so it was time to go out and have a look.
