Two months later, deep in the swampy jungle.

In the secret room of the Bai family, the aura suddenly concentrated in one place, and the place where it was concentrated was Ren Qingfeng, who was sitting upright.

I saw that his eyes were closed, and it was very calm to look up.

But his aura is not calm, the aura around him is continuously absorbed by him, and he is in the middle of the impact foundation building!

The True Qi in the sea of Qi was surging, increasing dramatically, and Ren Qingfeng carefully controlled the flow of True Qi.

This process is not easy, if you are in a hurry, then the true qi will burst into the sea of qi, hurting the spiritual root, the injury is small, and if you don't do it, it will be regressive.

If it is too slow, then it will never be able to sublimate the qi sea, and then it will not be able to enter the middle stage of foundation building.

The foundation building period is the next realm after the peak of the Qi cultivation period, and after the cultivator enters the foundation building period, he will break away from the realm of mortals and officially enter the door of cultivation.

There are four stages in the foundation building period, which are the early stage of foundation building, the middle stage of foundation building, the late stage of foundation building and the peak of foundation building.

The so-called foundation building is to form the foundation laid by Jindan.

The more solid the foundation, the more likely it is to get married.

The amount and intensity of true qi in the middle stage of foundation building are about three times that of the middle stage of foundation building, and so on, the late stage is three times that of the middle stage, and the peak is three times that of the later stage. And every time you advance, because of the irrigation and nourishment of the aura of heaven and earth, it will make the body more tenacious and strong.

Under the layers, the gap between the cultivators at the peak of foundation building and the cultivators at the early stage of foundation building can be imagined.

Theoretically speaking, it is not necessary to wait until the peak of the foundation to try to tie the Dan, and you can also try it in the early stage of the foundation, but the success rate is pitiful, because its foundation is too little, once it fails, the sea of qi of the foundation collapses, and the light will be seriously injured, and the heavy will fall.

Therefore, cultivators usually wait until the peak of foundation building to impact the Jindan Realm, when the foundation is full and the foundation is solid, and the success rate can reach one percent.

Don't look at the low probability of one percent, you must know that the success rate of hitting the Jindan realm in the early stage of foundation building is less than 1 in 10,000!

Moreover, even if the attempt to build the foundation fails, it will not hurt the fundamentals, at best, it will return to the middle stage of foundation building.

This is very similar to the cultivation method of the fighter, but there is no concept of Jin Dan in the fighter's cultivation system, and the fighter is only pursuing a majestic and powerful fighting spirit.

At this time, Ren Qingfeng has reached a critical moment in the middle of foundation building, and the sea of qi will be full and will be sublimated.

He manipulated his true qi and was extremely careful.

"Break it for me!" Ren Qingfeng shouted.

The true qi in the sea of qi was like substance, colliding and condensing with each other, emitting a dazzling milky white light.

"Boom!" Finally, the sea of qi stopped the waves, and the wind and waves were calm, as if the fury just now had not happened at all.

"It worked!" Ren Qingfeng opened his eyes and stood up.

Feeling the powerful true qi in the sea of qi far beyond the initial stage, he was overjoyed.

Arrogant, he took out a sharp sword, raised his hand and waved, and a sword qi slashed out.

Bombarded on the stone wall on one side.

I saw that this hard stone wall made of bluestone was actually slashed out by this sword qi and blasted out of a large pit with a diameter of nearly five meters.

"It's powerful!" Ren Qingfeng nodded slightly, "If this move hits the lord-level giant python that I encountered in Maple Leaf Ridge, it will definitely be able to break through its phosphorus armor, and the final result will definitely be that I win." ”

"The strength of True Qi in the middle stage of foundation building is similar to that of a sixth-order fighter, if the opponent is still a fierce cat in this swampy jungle..."Ren Qingfeng recalled the process of fighting with the fierce cat, "Although there is a battle strength, it is still difficult to win. ”

The Dou Qi Pill is almost consumed, and the few remaining ones are not of much use.

"Dousheng Dan!" He took out this elixir, which was extremely precious to the fighting master.

You must know that even if the price of a Douqi Pill in the academy is lower than that outside, it will reach two thousand amethyst coins.

That's the price of a low-level Yellow Rank Bucket Weapon!

And Dousheng Dan, 30,000 amethyst coins, ordinary fighters are willing to spend money to buy one when they hit the next class.

The price of a low-grade Xuan-rank bucket weapon is 100,000 yuan, and three Dousheng Pills are almost able to catch up with a low-grade Xuan-rank fighting weapon.

The value of an ordinary fighter is only about 200,000.

"No matter how precious the elixir is, it is still used for cultivation. Ren Qingfeng took out a Dousheng Pill.

"It's true that it can be converted into strength!" Let the breeze swallow it.

Impact the late stage of foundation building!
