Dear Lingshi

The bone shrinking technique is actually the same as the shape-changing technique that Lu Yunsheng had learned before, but the bone shrinking technique is more advanced than the shape-changing technique.

The Shape-Changing Technique is to change one's appearance and shape by circulating one's true energy, which makes it easy for cultivators at a higher level to discover the flaws.

This bone shrinking technique uses blood and qi to directly change the shape of bones, thereby completely changing a person's appearance and body shape. This change from the root is more covert than the shape-changing technique.

After Lu Yunsheng understood it, he naturally would not miss this secret method.

"Blood Yuan Finger, Blood Soul Sword Technique, One Yuan Heavy Sword Technique."

Lu Yunsheng looked at these dazzling methods of attack and killing and passed them by completely. Now he had no shortage of offensive means. Even after he broke through the Xuandan realm, he only roughly studied the seal method that came with the Xuanyuan Rouhuan Order.

Back then in Xiu Hanze, Lu Yunsheng had seen Tong Lu forcibly perform the first level of the seal technique, the Kaishan Seal, in the Fumai Realm.

In fact, this seal method is extremely powerful and has extremely high requirements for qi and blood. Even the first level of the seal method, the Kaishan Seal, has to wait until the Xuandan stage to be performed. After Lu Yunsheng had a brief understanding of this seal method, he planned to condense the Xuanying when the time comes and start practicing directly from the second level, the more powerful Blood Dragon Seal.

After all, he has no shortage of offensive and killing methods now.

After quickly browsing the first level of skills, Lu Yunsheng went directly to the second level.

Lu Yunsheng discovered that the higher the floor, the more profound the collected secrets became, but most of them were offensive techniques. Lu Yunsheng went all the way up to the sixth floor and finally discovered another extremely interesting secret technique here.

This secret technique is called Pure Yang Fist. It has only four moves in total, but it includes finger techniques and fist techniques, and is quite powerful.

This is still secondary. What makes Lu Yunsheng curious is that this secret method can actually temper the body when practicing. However, the only drawback is that to practice this secret method, the physical realm needs to reach the Xuandan stage.

"Pure Yang is fire, the body is the furnace, and Qi and blood are medicine. Use the furnace to refine medicine, and use the medicine to nourish the furnace." Lu Yunsheng looked at the contents of this secret method and recited it out loud involuntarily.

"Interesting!" Lu Yunsheng couldn't help but laugh happily as he watched. This Pure Yang Fist actually uses some specific movements to draw the pure Yang power between heaven and earth into the body, and then combines it with Qi and blood to achieve a certain effect of tempering the body.

After Lu Yunsheng memorized this secret method, he continued to move forward, but in the next few floors, he did not find any secret method that excited him.

After returning to the secret room, Lu Yunsheng couldn't wait to start practicing.

With his current state of mind, it only took him a few days to master the four secret techniques: Blood Robe Technique, Blood Shadow Escape, Bone Shrinkage Technique and Inch Step Technique.

However, the profundity of the Pure Yang Fist was beyond Lu Yunsheng's imagination.

The first move of the Pure Yang Fist is called Pure Yang Drill, which is a boxing-type move. Lu Yunsheng originally thought that he could easily learn it with his current physical cultivation at the early stage of Xuan Dan.

But he couldn't bear it anymore after just practicing for a cup of tea.

After resting for a while, Lu Yunsheng stood up, set up his posture again and began to practice according to the content of the exercises.

As he performed simple yet mysterious movements, Lu Yunsheng began to feel a slight heat flow into his body.

"This heat flow should be pure yang energy." Lu Yunsheng thought to himself.

Driven by this heat flow, the qi and blood in Lu Yunsheng's body began to stir again. At the same time, there was a burning sensation spreading from the middle dantian in his chest to his entire body.

Not long after, the blood and qi in Lu Yunsheng's body began to boil. This situation only occurred in the initial stage of boiling blood.

The difference from the boiling blood and qi in the Boiling Blood State is that now the blood and qi in Lu Yunsheng's body are boiling with an extremely unbearable heat.

He felt like there was a pot of boiling water inside him.

"Persevere!" Lu Yunsheng gritted his teeth and encouraged himself secretly.

By the time Lu Yunsheng had barely completed the first move of the Pure Yang Drill, his robe had already been soaked with sweat.

Seeing this, Lu Yunsheng simply took off all his clothes and continued to practice wearing only a pair of pants.

After practicing three times in a row, Lu Yunsheng could no longer hold on. He sat down on the ground, panting, and thought to himself, "This boxing technique looks simple, but it is more tiring to practice than climbing the Dragon Subduing Tiger Mountain. It seems that it really has the effect of tempering the body."

After pausing for a moment, Lu Yunsheng took out a third-level Qi and blood pill from his storage ring and swallowed it. The consumption of Qi and blood from practicing this boxing technique was also terrifying. After just doing a few simple movements, most of the Qi and blood in his body had been consumed.

When the medicinal power contained in this Qi and Blood Pill spread in his body, Lu Yunsheng immediately activated the Xuanyuan Rouhuan Order to refine the medicinal power and restore his consumed Qi and blood.

The next morning, Lu Yunsheng walked out of the secret room and looked for a bare mountain top near the two gates.

There are no trees on the top of the mountain, only a huge bluestone. This place is very suitable for practicing the Pure Yang Fist.

The reason why Lu Yunsheng came here to practice was because of a sentence recorded in the Pure Yang Fist: "Practicing this skill under the sun can achieve twice the result with half the effort. Practicing at noon is even more effective, but it can only be practiced once in a lifetime."

After Lu Yunsheng had a preliminary understanding of this technique yesterday, he decided to go outside today to try it out and see what the difference was.

Lu Yunsheng leaped onto the boulder and found that it was not only wide but also very flat, making it a perfect surface for practicing this boxing technique.

Although it was not yet noon, the sun had already risen halfway up the sky. Lu Yunsheng did not waste any more time and set up his position directly on the boulder.

As soon as he started practicing, Lu Yunsheng clearly noticed something different.

At this moment, he felt a pure yang energy that was even more intense than the one he had experienced during last night's practice, flowing into his body through the acupuncture points all over his body.

"It's so hot!" Lu Yunsheng exclaimed.

As soon as this hot pure yang energy entered his body, Lu Yunsheng found that a hot current was rising from his chest.

As the two streams of hot air converged in his body, the horrifying feeling of heat almost made him lose his mind, as if there was a furnace inside his body.

Lu Yunsheng exclaimed, then quickly clenched his teeth and continued to perform the Pure Yang Diamond movements meticulously.

He had soaked in the glacier of Fuhumen countless times and had also experienced using thunder tribulations to temper his body. It can be said that Lu Yunsheng had extremely rich experience in tempering the body.

What does it mean to temper the body?

To put it simply, the body is kept in an extreme environment for a long time. The process of adapting to the environment is actually slowly increasing its strength.
