Gao Cheng's body at this time has a thousand catties of huge strength, and the muscle strength and large tendons are far beyond ordinary people after tempering. With his current physical fitness, he could completely start cultivating the fourth level of the Golden Bell Jar Secret Thirteen Styles in one step.

However, for the sake of safety, Gao Cheng still tried it according to the cultivation methods of the first three layers. After breaking more than a dozen wooden sticks, Gao Cheng asked the martial arts hall disciples to slap with iron rods in their hands.

The sound of the iron rod slapping on the muscles continued to sound, Gao Cheng's skin turned red, and his brows moved slightly. His fists were clenched, and he was still motionless, blocking a full hundred bombardments. More than a dozen martial arts hall disciples gasped, their faces were pale, just now more than a dozen people took turns in battle with iron rods, Gao Cheng had nothing to do, but they were exhausted and almost paralyzed to the ground.

"Young master, are you okay?" Zhao Xuan, who was not far away, was terrified, lest Gao Cheng be injured by the iron rod.

Gao Cheng moved his hands and feet, and felt that his body was a little hot, and his skin and muscles were red from the iron rod. He said, "Don't worry, I'm fine, did I let you boil the water?"

Zhao Xuan hurriedly said: "It's already good, and according to the young master's orders, all the medicinal materials have been put in!"

Before cultivating this horizontal practice kung fu, Gao Cheng had already prepared according to the methods in the cheats, and even if he was injured, he could recover quickly through medicinal baths and the nourishment of qi and blood.

Zhang Shaotian saw more than a dozen disciples lying down tiredly, and secretly felt shocked by Gao Cheng's physical strength in his heart, and then stepped forward and said: "Gao Shaoxia, I will take the disciples back first, if Shaoxia still wants the disciples of the martial arts hall to help, just send someone to say it!"

Watching other people practice on the rivers and lakes is a big taboo, and slapping the body with wooden sticks and iron rods is not a secret for horizontal practice of kung fu, but the next medicinal bath is the core of horizontal practice. In view of this, Zhang Shaotian took more than a dozen disciples back with a very good eye to avoid suspicion.

Gao Cheng didn't be polite to him, nodded, and after he left, he came to the room next to the martial arts training ground, this room had no decoration, no tables and chairs, only a huge wooden barrel was placed in the middle of the room, and there were many medicinal herbs around.

At this time, the water vapor in the wooden barrel is steaming, and many strange-shaped medicinal herbs have been steamed in it, and all the medicinal power has been infiltrated into the water, and the hot water in the wooden barrel is slightly red, and when you smell the medicinal gas, you can feel the qi and blood begin to boil.

"This prescription...... It also seems to have the effect of nourishing qi and blood! It is similar to the Tiger Bone Blood Replenishing Soup in the Three Kingdoms World! And the effect is much more powerful than the Tiger Bone Blood Replenishing Soup!"

Gao Cheng sensed it slightly, and a thought suddenly popped up in his heart, "In the Three Kingdoms World, such a prescription for speeding up cultivation is a secret recipe that has never been passed on by a family. Cultivating exercises and auxiliary prescriptions is the foundation of a family. The four prescriptions recorded in the Golden Bell Jar Secret Book seem to be even more valuable than I imagined!"

Plop, Gao Cheng didn't continue to think, jumped into the wooden barrel, the boiling hot water suddenly surrounded him, and the medicinal power in the hot water began to flow down the pores of his body, constantly seeping into the skin and muscles......

The place where he was hit by the iron rod just now was stirred by the medicinal power, and it suddenly became hot, and the nearby qi and blood began to boil, Gao Cheng could feel a trace of medicinal power turned into qi and blood energy, constantly strengthening and repairing the wound.

"I see!"

Gao Cheng suddenly realized that the Tiger Roar Gong was to nourish the body and increase strength through food supplements. The Thirteen Secret Styles of the Golden Bell Jar are made through medicine, first destroying and squeezing the muscle tissue, and then using medicine to repair it, and strengthen the body in the process of continuous destruction and repair. The power added by this method is twice that of Tiger Roar.

It's just that such a method is already close to the devil's way, and only in pursuit of great power without regard for the body, if you are not careful, it will lead to serious consequences.

After soaking in the wooden barrel for more than half an hour, I added hot water two or three times, and the reddish hot water gradually became transparent. The medicinal power inside has been absorbed.

Gao Cheng left the barrel to change into clothes, his powerful spiritual power could sense that today's cultivation had increased the strength of his body a little, and the strength of his muscles had also increased a little.

"It's not bad, this exercise has some effects, but the first three layers don't have much effect on me, I can directly cultivate the fourth layer!

After feeling the effect of the Golden Bell Jar's Secret Thirteen Forms, Gao Cheng immediately decided to replace the Tiger Roar Gong with this technique and become one of the foundations of the Nine Yin Bone Breaking Gong.

At night. Gao Cheng consumed three hundred Destiny Points, integrated the first three layers of the Golden Bell Jar into the Nine Yin Bone Forging Skill, and then consumed a full thousand Destiny Points, which fused the fourth layer of the two exercises together.

"The fourth layer of the Nine Yin Bone Forging Skill (increases the strength of two thousand catties, increases the qualification of forty percent bones, strengthens the bones of the whole body, and enters the steel and iron bones)"

Gao Cheng saw the data displayed on the gray light curtain transformed by the Gate of Destiny, and his face showed ecstasy. As long as he reaches the fourth layer, his strength will be raised to a notch again. Especially the entry-level steel and iron bones displayed behind the Jiuyin Bone Forging Skill made him even more excited.

There are nine layers of training, of which the fourth layer is the Quenching Bone Realm. This realm is to refine the bones of the cultivator's whole body, and the stronger the bones, the stronger the strength the cultivator has. The strength of all the samurai at this level changed day by day, increasing rapidly.

Only when a martial artist cultivates to this realm will he have truly powerful strength, and this is the only stage where a martial artist can increase his strength the fastest. After the bones are refined, the cultivator has cultivated to the limit of the human body. It's hard to increase your strength.

The fifth layer of training strength is the Tongli realm! When a martial artist cultivates to this realm, he can integrate the strength of his whole body, and he can give full play to his own strength with his gestures. Condensed into energy.

The sixth layer of training strength is the realm of steel and iron bones! The limit of the strength training warrior strengthens the body, the body is like an iron casting, and it is difficult to hurt the sword and gun. This level can only be refined by breathing and breathing. Samurai at this level are qualified to command 10,000 troops in the Han official army of the Three Kingdoms World.

And the fourth layer of the Nine Yin Bone Forging Skill allows Gao Cheng to have part of the ability of the sixth layer of training when he is practicing the fourth layer, and the entry-level steel and iron bones can increase his physical strength by at least thirty percent. It can resist ordinary sword slashes.

Gao Cheng couldn't help but laugh when he thought of this. "The ordinary martial arts training warriors in the Three Kingdoms World, even if they reach the sixth level of training, the increased strength is not two thousand catties! As long as I break through to the fourth layer, I can sweep most of the sixth-layer martial artists! As long as I am not unlucky enough to meet extraordinary generals, coupled with steel and iron bones to resist dark arrows, swords and guns, there should be no problem with such strength to save my life in the chaotic army!"

At this time, Gao Cheng could finally breathe a sigh of relief. The sense of urgency in my heart was reduced a little. He came to the Condor World to have enough time to cultivate and have the strength to protect himself and Gao Tai and others. Now there is only one step left to complete the goal.
