Immortality: Starting as a Butcher to Level Up in Cultivation!

Inside the cultivation room.

Wei Hong sat cross-legged on a golden silk futon, his eyes tightly closed.

After storing both secret techniques into the system, he planned to first cultivate the 【Blood Fiend Secret Technique】.

Currently, he didn't have many life force points left, so he could only temporarily upgrade the 【Blood Fiend Secret Technique】 and the 【Six Armor Secret Incantation】's Lin character formula to the proficient realm.

He still needed to reserve some life force points to improve his refining skills.

After upgrading the 【Blood Fiend Secret Technique】 to the proficient realm, Wei Hong officially began cultivating this secret technique.

According to the records in the jade scroll and the cultivation insights absorbed during the realm upgrade, he first circulated his own cultivation method, gathering all his mana in his dantian.

Then, at the center of the mana vortex, he slowly drew out a trace of fiendish energy hidden deep within his body.

This fiendish energy was like a wisp of black smoke. As soon as it appeared, it caused a burst of stinging pain in his dantian, as if countless tiny needles were pricking him.

Wei Hong endured the pain, carefully guiding this wisp of fiendish energy, enveloping it with mana, and then guiding it to slowly travel along his meridians.

As the fiendish energy slowly circulated through his meridians, Wei Hong's body began to change.

A faint black halo appeared on the surface of his skin, and his muscles tensed up involuntarily, as if every muscle was trying to break free from the constraints of his body.

Wei Hong could feel his strength gradually increasing, but this increase in strength was accompanied by great pain. His meridians felt like they were being torn apart by a powerful force, and there was a risk of them breaking at any moment.

In order to control this fiendish energy, he didn't dare to be negligent. He concentrated all his energy and focused all his mind on guiding the flow of the fiendish energy.

He constructed a mana channel in his mind, trying to make the fiendish energy run according to the route he set.

However, that trace of fiendish energy was like a mischievous child, always deviating from the route he set and scurrying around.

Whenever the fiendish energy went out of control, Wei Hong's body would experience a burst of severe pain, his face would become even paler, and beads of sweat would roll down his forehead, wetting the futon in front of him.

This was because it was his first time cultivating the 【Blood Fiend Secret Technique】. Even though he had used life force points to upgrade it to the proficient realm, the cultivation insights he had absorbed were not that abundant, so he couldn't precisely control that trace of fiendish energy.

When he could freely control that trace of fiendish energy, it would mean that he had successfully cultivated the 【Blood Fiend Secret Technique】.

Just when he was about to give up, Wei Hong suddenly remembered a key point mentioned in the jade scroll: use the heart as a guide, and use intention to control the energy.

At this moment, he suddenly realized that he had been too focused on the guidance of mana and had neglected the intention of his heart, so he immediately abandoned all distracting thoughts and concentrated his inner intention on that wisp of fiendish energy, using his firm intention to control the fiendish energy.

Soon, the fiendish energy that had been scurrying around became gradually docile under Wei Hong's powerful intention, and then slowly ran in the meridians according to the route he set.

Taking this opportunity, he immediately increased the guidance of the fiendish energy, and more fiendish energy surged out from the dantian, merging into his mana.

In the next moment, Wei Hong was blessed with inspiration, and his hands immediately changed their hand seals.

Buzz!

His body, along with the mana and fiendish energy within it, shook, and the mana immediately surged.

He could feel his strength increasing at an alarming rate. With every breath, he could feel the surrounding spiritual energy surging towards him like a tide, being absorbed into his body like a whale devouring it, and quickly transforming into mana.

The surge of mana naturally led to a rapid increase in strength.

However, this improvement came at a price. As the fiendish energy continued to increase, the pressure Wei Hong was subjected to within his body also grew. His meridians had been eroded by the fiendish energy to the point of being almost broken, and although his physical body had also been strengthened a lot, his internal organs were under tremendous pressure, and countless tiny cracks appeared on the surface of his skin.

Blood flowed from the various tiny cracks, dripping onto the futon.

His bones were also making "creaking" sounds, as if they would break at any moment.

Moreover, the essence blood in his body also began to burn, assisting the surge of mana like firewood.

Wei Hong was shocked and did not dare to continue drawing out the fiendish energy, and immediately stopped guiding the fiendish energy, because if he continued to draw out the fiendish energy in his body, his body might not be able to withstand the too rapid increase in strength and would explode directly.

"Hoo!!!"

After a while, Wei Hong finally breathed a long sigh of relief.

At this time, he was able to freely control the mana in his body, as well as the strength that had just surged several times.

The first time he successfully used the 【Blood Fiend Secret Technique】, he felt the domineering and power of this secret technique.

"As expected of an explosive, desperate secret technique, it really can't be used unless absolutely necessary."

Wei Hong murmured, but he was very satisfied with this secret technique.

He could clearly feel that although he had only drawn out a small part of the fiendish energy in his body during his first use, his strength had increased by at least three times. If he drew out more fiendish energy, it would naturally increase even more, but he could not control it at the moment.

One reason was that his realm of this 【Blood Fiend Secret Technique】 was not high enough, and the second was that he was not skilled enough. He still needed to practice constantly, so that he could slowly allow his physical body and meridians to adapt to the changes in the fiendish energy.

"However, the next time I cultivate, I don't need to go directly to the last step. I only need to constantly familiarize myself with the previous steps and let the meridians adapt to the circulation of the fiendish energy."

Wei Hong knew clearly that his first use was just to test the strength of this secret technique.

The next time he cultivates, he doesn't have to go to the last step, so that he won't completely use the secret technique, but just keep practicing the previous steps, and he can slowly improve his realm and become more familiar with it.

He subconsciously clenched his fists, and could feel the powerful power contained in them.

Moreover, the mana in his meridians was now building up, just like a volcano about to erupt. Once activated, it could unleash extremely terrifying power.

"With a three-fold increase in strength, I should be able to instantly kill that rogue cultivator at the third level of the Golden Core stage, right?"

With his original majestic mana, and then increased by more than three times, if he encountered that rogue cultivator at the third level of the Golden Core stage at this time, perhaps he wouldn't have to be so troublesome at all, and the other party would be killed on the spot with two spells.

However, such an improvement also requires a huge price. Wei Hong could feel that his meridians were becoming riddled with holes under the corrosion of the fiendish energy, and the injuries to his physical body were also rapidly expanding.

Although these injuries and side effects were temporarily not obvious under the surge of strength, Wei Hong knew very well that when the duration of the secret technique ended, these side effects would be completely revealed, enough to make a Golden Core cultivator wish he were dead.

A quarter of an hour later, Wei Hong clearly felt the ravages of the secret technique's side effects.
