Mortals cultivate immortality, and their IQ is playing with their heartbeats

Li Chengfeng's expression remained unchanged as he respectfully said, "Master, please go out with peace of mind. I will definitely take good care of the medicine field!"

"I'm giving you three hundred Qi Replenishing Pills. I'm leaving you all my savings of ten years. You must consume them this time. If you don't reach the fourth level of Qi Refining within a year, your fate will also be death!"

Tian Ku said in a gloomy voice, as if he had made some kind of determination.

Li Chengfeng felt like he was sitting on pins and needles. The Fallen Copper Coin had driven Tian Ku crazy, but instead, it had plunged him into a place of eternal doom. It was truly an ominous object.

Tian Ku threw a small bag to Li Chengfeng and said, "This is a storage bag. You can take things out by just scanning it with your divine sense. Inside are three hundred pills. I'll go back and pack up. Perhaps I'll leave tomorrow. Take care of yourself!"

He snorted coldly and returned to his own cave.

Sweat dripped from Li Chengfeng's forehead onto the ground. He realized that he was too naive in front of Tian Ku. Fortunately, he still had some value.

He dragged Wang Bao's body out and buried it next to the medicine field. Then, he fetched several buckets of water, washed the room clean, and closed the stone door.

The storage bag was indeed easy to use. As long as his divine sense enveloped it, he could see the things inside. Whatever he enveloped, he could take out. However, it could only hold inanimate objects, not living things. The storage bag was only one cubic meter in size, very small.

Li Chengfeng thought it was indeed a good treasure. Inside were thirty bottles of pills, ten pills per bottle.

Tian Ku had quite a lot of savings over the years, but would there be significant side effects from taking these pills? If he didn't take them, his strength wouldn't improve.

Li Chengfeng decided to take one pill to experience it and then make a decision.

The pill was too potent upon entering his stomach, emitting a violent aura. He could only use his Qi vortex to grind and scour it, expelling the spiritual energy within the pill and removing the impurities from his body.

This Qi Replenishing Pill was obviously substandard, with an overly strong bloody aura. Such rapid improvement in strength would definitely leave hidden dangers.

Over time, a large accumulation in the body would be equivalent to ruining his future. Tian Ku had no good intentions. The only thing he cared about when refining these pills was their powerful medicinal properties, forcing rapid growth and making his cultivation advance by leaps and bounds.

It took Li Chengfeng a full six hours to refine one pill. A trace of impure bloody energy was added to the pure spiritual energy of his Qi vortex.

Taking pills was much slower than extracting spiritual energy.

After thinking it over, he decided to first extract one-tenth of each Qi Replenishing Pill's spiritual power. Once he advanced to the third level of Qi Refining, he would definitely be able to refine the Qi Replenishing Pills much faster with a third-level Qi Refining vortex.

Li Chengfeng was relatively clever and could think about problems from various perspectives. Therefore, he didn't delay any further and immediately did as he planned. It took him more than an hour to extract one-tenth of the spiritual power from all the pills.

As expected, with a "boom."

His dantian finally became full, and his meridians were also swollen to the extreme. Everything came naturally. The Qi vortex expanded by another one-third, and the speed of rotation became even faster. The pressure increased, the meridians became more resilient, and his divine sense expanded to three thousand meters.

Ordinary third-level Qi Refining cultivators could only expand their divine sense to three hundred meters, a difference of ten times.

Advancing to the third level of Qi Refining was already difficult, but advancing to the fourth level would be even more so. The third level of Qi Refining was a watershed.

The next day, he came to the medicine field and cast the Rain Spell. Under the nourishment of the spiritual rain, the spiritual herbs were verdant and lush, growing vigorously.

Tian Ku's cave opened and then slammed shut with a "bang." He stuck a yellow talisman on it and said, "Your teacher will not return for another year. You all cultivate diligently. Zhang, the steward, will take care of your daily lives here."

Having said that.

He stepped on his flying sword and soared into the sky with a "whoosh," breaking through the air and leaving in a carefree and elegant manner.

Li Chengfeng breathed a slight sigh of relief. Now that the old guy was gone, he could think of a way to resolve the toxins in his body.

He didn't take any action. He meditated and cultivated, swallowing pills, and then sensing the impurities within the pills. This bloody energy remained in his body, which made him very distressed.

How could he refine this bloody energy? This bloody energy was within his dantian, mixed within his spiritual energy. He began to convert it into the power of life, but the bloody energy could not be integrated. He then converted it into the power of death, but the bloody energy still could not be integrated. He suddenly converted it into soul power, and the bloody energy suddenly merged into it. The soul and blood energy were compatible.

He then used soul power mixed with bloody energy to fuse the power of life and the power of death, making it more stable and without obstruction.

This allowed him to break through to a completely new cultivation method. Then he kept deducing and comprehensively cultivating, and it took him a month to finally solve the problem of the bloody energy in the pills.

Generally, when swallowing and cultivating pills, the Qi vortex is used to scour, break, and absorb the spiritual energy, and eliminate impurities.

Li Chengfeng allowed his soul power to form a vortex, his life force to form a vortex, and his death force to form a vortex. With these three vortexes formed, he could envelop the pill.

Then the three vortexes rotated rapidly, forming a powerful friction force. Normally, it would take a day of meditation to absorb one pill, but now it only took three hours to complete the absorption.

In the blink of an eye, three months had passed, and he had managed the medicine field in an orderly manner.

Steward Zhang Wei was a martial arts expert who had entered the Innate Realm, possessing great strength. He never spoke carelessly and always maintained a demeanor that kept people at a distance. All the food and supplies were delivered from above, and the ropes were quickly retracted, giving no one a chance to escape.

Zhang Wei led ten martial arts experts to supervise everything, allowing everything in the valley to operate in an orderly manner without any mistakes.

Li Chengfeng was not in a hurry to break through. At the third level of Qi Refining, he had almost exhausted ten bottles of pills, but the Qi vortex in his dantian had not yet been filled.

The main reason was that his Qi vortex was equivalent to three of other people's vortexes, and it was also more pure.

Steward Zhang Wei was a cautious person. He never spoke to anyone, never interacted with anyone, and did not prevent Li Chengfeng from killing him.

Because with him there, many things were inconvenient for Li Chengfeng to do. If he killed Zhang Wei, he could fully manage and control this place.

The third level of Qi Refining was strong, but he suffered from not having any spells. He was not the opponent of the other party. Fortunately, the Rain Spell was even more violent at the third level of Qi Refining. Hitting the stone wall could create a hole as big as a washbasin.

Li Chengfeng secretly observed that Zhang Wei's cave was heavily guarded, with several experts taking turns guarding the outside. Moreover, his stone door had a mechanism that would "click" when pulled, alerting the people inside if it was damaged.

Li Chengfeng discovered that his cave was two hundred meters away from Zhang Wei's cave. He decided to dig a tunnel from his side. Because his divine sense was strong, he could reach three thousand meters without any deviation.

Li Chengfeng first converted all the spiritual energy in his body into the power of death, and his whole body was filled with death energy, like a ghostly zombie. His hands were like knives, and with a grab, rocks flew and he began to dig.

In this way, for half a month, he finally quietly opened up a tunnel. All the rubble was cleared out by him, loaded into the storage bag, secretly taken out, sprinkled in a corner not far away, and then buried with soil.

He stopped ten meters away from Zhang Wei's cave. He could only start digging when Zhang Wei left the cave to avoid arousing the other party's suspicion.

Another five days passed, and it was only half a meter away.

Li Chengfeng began to prepare for the assassination. He first familiarized himself with the feel of stabbing with the dagger.

He also practiced the Rain Spell hard for ten days. He could cast three explosive water droplets at a time, and the three droplets could quickly fuse together and explode when activated. The power could blast open a pit of two cubic meters. He had to kill with one blow.
