The Flux Finger Sword Technique wasn't a technique one could learn easily. Firstly, it had harsh requirements on the quality of one's finger bones. The finger bones had to be strong enough to withstand the flow of flux goldthorn energy, or one should just forget about using one's fingers as a sword.

Although Xiang Shaoyun had cultivated the Vicious Prison Finger technique before and had finger bones much more durable than a regular person, his finger bones were still not strong enough to withstand the power of the flux goldthorn energy. He still needed to give his fingers some tempering.

Since his soul clone was much stronger than his main body, the clone would have a much easier time practicing the technique. Even so, each time the clone tried using the technique, its fingers would suffer the pain of getting stabbed by countless needles. His only option was to withstand the pain. He would only be able to use the technique after he completely adapted his finger bones to the flux goldthorn energy.

While his clone was cultivating the Flux Finger Sword Technique, his main body was cultivating the Limit Stimulation Technique. The Limit Stimulation Technique utilized a unique high-tier energy to torment one's skin, flesh, meridians, organs, and bones as one used the technique to withstand the pain. The resulting pain would push one's potential, bring one to one's limits, and make one forge a flawless physique.

Cultivating this technique was very much an act of insanity. One could very well turn mad from pain if one failed to withstand the suffering. Xiang Shaoyun had withstood the pain of flame, lightning, and flux goldthorn energy. His fortitude was far greater than a regular person's. Thus, he was willing to give the Limit Stimulation Technique a try no matter how hard it seemed.

He slowly guided the flux goldthorn energy, gradually spreading it over every inch of his body. The stinging sensation assaulted his entire body. He hurriedly started chanting the technique's mantra, using the mantra to harvest the power of pain. His pain intensified, and it reached a point where he started wailing in pain.

Fortunately, Xiang Shaoyun had laid down an isolation restriction in the area. Otherwise, his harrowing wails would spread a great distance. He felt like he had reached the very limits of what pain could feel like. Every inch of his body was suffering. His meridians, organs, bones, and so on were suffering a pain more than 10 times of what he was feeling when he first guided the flux goldthorn energy around his body.

He rolled on the ground, and in pain, he vented his suffering and threw out punches everywhere, leaving numerous fist prints in his surroundings. When practicing a technique like the Limit Stimulation Technique, the longer he withstood the pain, the better it would work. Thus, Xiang Shaoyun clenched his teeth and forced himself to maintain a sliver of consciousness.

Even when he bit into his tongue, he didn't feel it, as the pain he was feeling all over his body was much more intense. After persevering for an hour, he reached the verge of fainting from pain, and he finally withdrew the flux goldthorn energy. He collapsed weakly onto the ground, no longer able to muster any strength.

Even with the end of the torment, he did not fully relax. He was silently relieving the numbing sensation his entire body was feeling, and some impurities started seeping out of his pores. Soon, his entire body was wrapped by a layer of foul and viscous substances.

He had just undergone a body cleansing process, returning his body to the purity level of a baby's. Generally speaking, only extremely valuable treasures would be able to cleanse one's body in this manner. Using the Limit Stimulation Technique, apart from the cleansing, one could also strengthen one's body, discover one's hidden potential, and forge a filthless physique.

If Zang Yuan knew that Xiang Shaoyun was able to last an hour during his first cultivation session, he would probably jump out of his grave from sheer shock. After all, back when he first cultivated this technique, he had fainted before even lasting half an hour.

He was only able to last an hour after cultivating the technique for a year, achieving the same body cleansing effect.

Xiang Shaoyun's clone returned to the main body and shared in the benefit of the cleansing, allowing his soul to grow as well.

His plan was to stop cultivating the Flux Finger Sword Technique. Instead, he would be focusing on the Limit Stimulation Technique for a while to temper both his body and soul. When his body reached a certain level, his finger bones would also be able to reach a level where they could withstand the flux goldthorn energy. At that time, he would be able to form a sword with his fingers.

After an hour of rest, he felt much better. It was then that he smelled the stench on his body. He was disgusted and hurriedly used the profundity of water to wash himself. Only then did he feel better.

As he swung his arms around, he could feel that his entire body had turned swifter. His entire body was brimming with energy and life force, an extremely amazing sensation. It was as though his very pores were breathing in the air around him. His energy circulation had also hastened a lot, and his senses had improved considerably. In short, he was feeling something so wondrous no word was adequate to describe it.

"Worthy of being the Limit Stimulation Technique. The more pain I can endure, the more of my potential I can force out. The potential of mankind has always been boundless," muttered Xiang Shaoyun in a pleased manner.

After resting for three days, he finally recovered to his peak condition and got used to his cleansed body. He then went straight back to cultivating the Limit Stimulation Technique.

A new round of torture began. This time, he was also punching his surroundings and destroying everything. He wasn't exactly applying a lot of force, but his punches were too strong, and the rocks around him couldn't take his punches. He punched so hard his fists started bleeding. Terrible wounds appeared on his fists, wounds that were the result of him not using any energy in his punches.

An hour passed, and the cultivation session ended. Many impurities seeped out of his pores this time as well, but there weren't as many as the previous time. That was proof that the number of impurities within his body had reduced considerably.

Also, it was also probable that Xiang Shaoyun had lasted the same length of time with an improved body, so the technique wasn't working as well for him. Even so, he had still reaped considerable gains.

The more impurities he expelled from his body, the better he felt. Not only had his senses been enhanced, but his energy circulation had also increased in speed and responsiveness. It was as though he had been reborn anew.

An old tool would eventually deteriorate in quality, but when the tool was reforged and optimized, it would be a much better tool. That was what was happening to his body. His body was still young, but he had not cultivated it during his childhood.

Although he had soaked in many medicinal liquids to temper his body, it did not guarantee a body as excellent as someone who had cultivated since childhood. Through the Limit Stimulation Technique, he was able to slowly gain a body comparable to someone who had cultivated since young. Having such a constitution was very beneficial for his future cultivation.
