Chapter 159

Lin Cheng took the secret manual from the concubine's hand, his fingers rubbing it carefully, and said: "This is the Negative Mountain Bear Classic, which details the true qi operation routes and essentials for practicing Qi to Gang and cleansing the marrow. You can only read it at the Weiyuan Hall and return it to me before you leave; you can continue to come to me to get it tomorrow."

"Disciple remembers."

Xu Yang respectfully took it, feeling that the material of this secret manual seemed unusual; it was soft and very delicate, not like paper, and should be the skin of some strange beast.

Lin Cheng nodded and said: "Study it carefully, and strive to comprehend every essential before Qi Gathering Perfection, and practice Gang Qi in one go."

Gang Qi was much fiercer than true qi.

In the martial arts examination, the two Marrow Cleansing experts, Cao Rong and Yun Feng, only fought a few moves on the ring, and the entire ring was shaken down by the aftermath of their fight; in the end, the two fought on flat ground, almost destroying most of the school grounds.

"Master, why is Gang Qi so fierce, and what mysteries does it have?" Xu Yang asked, taking the opportunity.

"Gang Qi is the power of a martial artist's essence, qi, and spirit fused into one; true qi is formless and qualityless, like this air, although it truly exists, it is invisible to the naked eye.

But Gang Qi is different; it can already be seen with the naked eye, so its power is naturally extraordinary."

While speaking, a red glow erupted from Lin Cheng's hand, gradually covering his hand like crystal, although it was still transparent.

But it was indeed very different from true qi, no longer something that existed but couldn't be seen with the naked eye.

"You come and feel it."

Lin Cheng stretched out his palm covered with Gang Qi, like a work of art covered with a layer of red crystal.

"Good!"

Xu Yang pointed a finger at it; before he even touched the Gang Qi, he felt an astonishing scorching heat, and the invisible fluctuation seemed to want to melt his skin and flesh.

"Bang!"

An astonishing rebounding force came, and he only felt his finger bones vibrating, as if they were about to be broken.

Gang Qi was not only visible to the naked eye but also had a real tactile sensation.

"So strong!"

He couldn't help but be greatly surprised: "With this power to protect the body, even an expert at Qi Gathering Perfection couldn't be a match for a Marrow Cleansing expert."

"Qi Gathering Perfection?"

Lin Cheng laughed: "If an expert at Qi Gathering Perfection can comprehend the Mixed Origin Strength, they can still fight a few moves with someone who has just barely practiced Gang Qi, but that's only a few moves; an expert who has practiced Gang Qi killing a Qi Gathering martial artist won't exceed ten moves."

He paused for a moment and continued: "Do you know why it is said that the Mixed Origin Strength is the exclusive killer move of Marrow Cleansing experts? Because Qi Gathering martial artists need to comprehend the Mixed Origin Strength to achieve the unity of internal and external, the unity of mixed origin.

But after Marrow Cleansing experts practice Qi to Gang, they are also unified internally and externally; everyone is unified in mixed origin, and the other party's power level is stronger than yours, so how can you fight?"
