With Xu Xuan's fourth level of Qi Refining, even if he breaks through the first level, it will be difficult to reverse the situation.

Xu Xuan decisively closed his eyes, sat cross-legged in the underground secret room, and began to practice.

He has his own reason for doing this.

First, in the stage of meridian opening, at a critical moment, taking one step forward, you can open up the first step of the five internal organs and five elements, the main fire!

Secondly, Xu Xuan has a large amount of Tianhuo Spirit Liquid, which is faster to improve his cultivation. He is now at the peak of the fourth level of God Refining.

In addition to these two points, Xu Xuan's strength can be increased by at least half, and he will be more sure of breaking through at that time.

He closed his eyes and began to mobilize the energy in his body, running along the mysterious trajectory of the hidden vein.

The hidden meridians are not meridians and acupoints, but are the magical pulses of the human body. Their trajectory lines exist in three-dimensional space and pass through the flesh and blood body composed of qi, blood, veins and bones.

In less than two days, Xu Xuan began to attack the second one. In order to speed up, he took out the seven-sided jade bottle.

A few drops of Tianhuo Spirit Liquid were suspended in the air, emitting a hot and heart-burning pressure.

A layer of red light appeared in Xu Xuan's palm, allowing a drop of Tianhuo Spirit Liquid to seep into it.

In an instant, a terrifying flame force rushed into his body along the fire element, burning every inch of Xu Xuan's flesh and blood.

Xu Xuan immediately guided this force to move in the hidden vein and felt that his own energy became stronger and stronger in the repeated impacts.

Just a drop of Tianhuo Spirit Liquid, Xu Xuan broke through a hidden vein.

"boom!"

A roar in the body, the flame force is like a fierce horse, strengthening diligence, opening up the deeper potential and strength of the human body, improving bloodlines and rising senses.

The Yuanli was circulating and moving in the hidden vein again and again, and Xu Xuan stepped into the fifth level of the God Refining without any obstacles.

The aura of his promotion was emitting, and the few people in the sand boat felt it and were shocked.

"I remember Brother Xu entered the fourth level of God Refining last time, but it took only two months."

Wang Shui was shocked.

Yanmei and the other three were also shocked.

Unexpectedly, Xu Xuan said he would go to the fifth level of God Refining when he was in seclusion. This speed was too terrifying.

However, what surprised them was that Xu Xuan was still practicing after being promoted to level one.

Three days later, Xu Xuan used three drops of Tianhuo Spirit Liquid to open the third one, and the Yuan power became more powerful and more diligent. Although this was far from enough to break through the sixth level, Xu Xuan felt an indescribable energy deep in his body.
