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

Before long, all ten pills had their medicinal power extracted and refined by Li Chengfeng. Of course, nine-tenths of the medicinal power still remained in the pills.

Li Chengfeng wouldn't consume them. The fishy smell they contained made him feel inexplicably dangerous. Now that he had the Qi Refining Second Layer cultivation method,

he meditated and cultivated, but the spiritual energy was too thin. Having grown accustomed to rapidly increasing his spiritual energy, this kind of cultivation made him feel extremely dissatisfied.

He quickly opened his eyes and discovered that his Qi vortex had barely changed.

He still needed pills to improve his cultivation. Otherwise, with his aptitude, he probably wouldn't be able to break through by cultivating step by step.

He had no choice but to begin researching the Rain Summoning Technique. Mobilizing the spiritual energy within his body, slowly, moisture began to condense within the cave, then transformed into a light, drizzling rain, sprinkling onto the cave walls.

He succeeded on his first try. Li Chengfeng possessed an extraordinary comprehension ability when it came to cultivation methods and secret techniques, which was inextricably linked to his soul.

Then, he repeatedly deduced whether the Rain Summoning Technique could be used to kill. In truth, any cultivation method, if used properly, could be used to kill.

But the Rain Summoning Technique could only drench an enemy in water. How could that kill?

What if there was poison in the water? His eyes shone. Thus, he converted his spiritual energy into death energy. The death energy was vast, and the water mist turned grayish-white.

His body, from top to bottom, was as dry and cracked as old tree bark, filled with the scent of death and decay. Once again, he activated the Rain Summoning Technique. With a "whoosh," black raindrops poured down from the sky, splattering on the stone wall and emitting a sour, rotten smell.

Li Chengfeng walked over to inspect the stone wall, finding it covered in pitted potholes. It was indeed effective.

What would happen if raindrops mixed with the power of life and death were used simultaneously?

This idea seemed easy but was actually very difficult. He slowly deduced it for a day but couldn't find the answer. Only a few scattered drops landed on the stone wall.

With a "bang," a fist-sized hole exploded in the stone wall. Because the two forces didn't fuse, he used a bit of soul force to wrap them. The collision of the two forces formed an explosion. What would be the scene if these raindrops, packed with explosions, were sprinkled on a person?

However, he couldn't do it yet. It would consume too much spiritual energy, and even more soul force.

Li Chengfeng had to find a new balance point.

In the evening, he went to the medicinal field. Last time, he extracted the spiritual power from thirty plants. Now, he extracted the spiritual power from the remaining ninety spiritual herbs.

This caused the spiritual energy within his body to become saturated, with faint signs of a breakthrough. This made his expression turn solemn. If he advanced to the Qi Refining Third Layer, it would be too fast, and his foundation would probably be unstable.

He wasn't in a hurry to break through. Instead, he felt that his body's progress was too fast and not a good thing. He needed to solidify the foundation of the Qi Refining Second Layer.

During cultivation, cultivators inevitably absorb some useless impurities into their bodies.

Li Chengfeng had a sudden idea and used "Drawing Energy from the Source" on himself. He chose waste energy. The Qi vortex shrank by one-tenth, and the waste energy inside was drawn away, making the spiritual energy even purer.

Li Chengfeng practiced the Rain Summoning Technique and noticed a drop of gray-brown rain at his fingertip, half gray and half green, with a black line perfectly separating them.

He flicked his finger. With a "swoosh," guided by his spiritual sense, the raindrop accurately struck the wall not far away. With a "bang," a bowl-sized hole immediately exploded in the stone wall, two or three times stronger than the first time.

Sure enough, as his spiritual energy became purer, its power also became stronger. It could kill Tian Ku by surprise.

Li Chengfeng always felt that Tian Ku's strength was even greater and that he possessed some kind of treasure. He wouldn't act without absolute certainty and had to endure.

After completing his tests, he meditated to recover a bit of spiritual energy. The stone door was knocked with a "tap, tap, tap."

He opened it and saw Wang Bao.

Wang Bao was the oldest of the three youths.

He said with a smile, "Senior Brother, can I come in and ask you about some cultivation problems? There's something I don't understand, and I'm afraid of being scolded if I ask the master."

His complexion looked somewhat unpleasant, indicating that he was probably having problems with his cultivation. Wang Bao's thoughts were more complex than the other two youths.

Li Chengfeng's pupils shrank as he carefully observed the other party's pupils, noticing a trace of panic, hidden extremely well, but captured by him, along with a hint of ruthlessness.

He immediately became vigilant. This kid had bad intentions, but his expression remained normal.

"If you have any cultivation difficulties, feel free to speak. This senior brother will answer them for you."

The two sat cross-legged facing each other.

Li Chengfeng appeared nonchalant, but his fingertips were subtly trembling, secretly operating the Rain Summoning Technique to condense a water droplet at his fingertip. A yin-yang fish-like water droplet was gently rotating, concealed by his sleeve.

"It's like this. I encountered a bottleneck when I was about to advance to the First Layer. I don't know how to break through. Please enlighten me, Senior Brother."

Wang Bao put on a humble appearance of seeking guidance.

Li Chengfeng said, "You can only move forward bravely. We cultivators fight with the heavens and the earth. You must never be discouraged when you encounter a bottleneck. No matter how painful it is, as long as you have an invincible belief, you will definitely be able to break through."

Wang Bao nodded gratefully and said, "Thank you for your guidance, Senior Brother. Without you, I really wouldn't know what to do."

Before he finished speaking,

he suddenly pulled out a sharp dagger from his waist and leaned forward, stabbing towards Li Chengfeng's left chest.

Wang Bao believed that his speed was very fast, but in front of Li Chengfeng, it was deadly slow. Li Chengfeng was already at the Qi Refining Second Layer Completion, and his spiritual sense was even stronger.

Li Chengfeng sneered, raised his hand, and instantly flicked out the water droplet, striking Wang Bao's chest. With a "bang," Wang Bao was sent flying by the huge impact, his back crashing into the stone wall. He fell to the ground, wailing in pain.

A large hole had exploded in his chest, with his internal organs faintly visible and blood gushing out.

He looked at Li Chengfeng in disbelief, filled with fear and unwillingness.

"How did you know I was going to kill you?"

"Your eyes were flickering, hiding murderous intent, and I don't trust anyone. I'm always ready to counterattack," Li Chengfeng's pupils narrowed slightly.

Wang Bao said helplessly, "I didn't expect you to be hiding so deeply!"

"Why did you want to kill me?"

Wang Bao said, "Because you're too excellent. You stole our light. We only just sensed Qi, and you've already advanced to the Qi Refining First Layer. In the future, the master will pass on his mantle to you. I killed you in advance, and I'll be the senior brother!"

Li Chengfeng looked at him with pity and said, "You're really foolish. Do you think the master is sincerely teaching us immortal methods? We're just his pawns!"

"Impossible!"

Wang Bao shook his head in disbelief.

Li Chengfeng walked up to him and said, "People die for wealth, and birds die for food. Is it worth risking your life for illusory benefits!"

After speaking, Li Chengfeng used "Drawing Energy from the Source" on him. He chose soul force.

Wang Bao let out a scream. One-tenth of his soul force was extracted. Li Chengfeng sent the soul force into his sea of consciousness, and his soul opened its large mouth and swallowed the soul force in one gulp.

Li Chengfeng felt his soul force strengthen slightly. It was indeed effective, but unfortunately, he could only extract it once.

Wang Bao died completely after his soul force was extracted, and his incomplete soul couldn't enter reincarnation.

At this moment, Wang Bao's fragmented soul gathered towards his chest.

Li Chengfeng tore open his shattered clothes and found an old copper coin, covered in rust and tattered. The soul was absorbed by the ancient coin.
