Gu Tianfeng stood in the quiet courtyard, like the moonlight of water sprinkled down, turning him into a silver man.

"Buzz !!"

A light tremor came, Gu Tianfeng's body froze, his face changed, and he immediately sat down cross-legged, feeling the changes in his body.

That strange fluctuation came from his soul, and almost instantly, he entered a state of 'inner vision'.

In the soul space, this place is always so white, sacred and noble, like being in a pure divine lotus, there is an intoxicating fragrance.

The soul is the core of the human body, and when the soul is destroyed, the person dies.

Gu Tianfeng didn't dare to be careless at all, and probed the abnormality of the soul.

"Huh?" he groaned slightly, feeling dazzled, "how do I feel that my soul has become more brilliant and more dazzling?"

Indeed, a soul like a small sun, floating behind the vast soul space, emitted a soft light, and its surroundings were filled with soul power.

"I read that right, my soul has really grown, and I can feel more energy coming out. Gu Tianfeng was ecstatic.

Compared to before, the soul at this moment has indeed grown stronger, and the energy emitted is even stronger.

It suddenly occurred to him that the master had said that the soul can be regarded as a person's mind and a person's willpower.

When a person's willpower is weak, the soul fire can be very weak.

It's like a dying man whose willpower is already so weak that the fire of his soul can be extinguished at any moment.

"After listening to the master's words, my heart is like a rock, and nothing can shake my determination, and my Dao heart is more stable than before. Gu Tianfeng pondered, "Could it be that it is precisely because of this that my soul fire has become more brilliant?"

His eyes flickered, as if he had thought of something.

"Willpower is the embodiment of the soul, the stronger the soul, the stronger the willpower... The stronger the willpower, can the soul also be improved?" Gu Tianfeng half-squinted his eyes, slowly spoke, and said: "If the cultivation of the soul is the same as the cultivation of strength and artistic conception, then can I apply the principle of fusion and rebellious cultivation." ”

This is a huge change, arguably an unprecedented breakthrough.

Because, the soul is ethereal, no one dares to try it casually, and if you are not careful, you will perish directly.

His thoughts are extremely crazy, but Gu Tianfeng is very sober, time and everything are connected by an invisible chain, and there is always something in common.

What is willpower?

You are beaten half to death and you don't say a word, just because you don't want to give in, this is called willpower.

In the snow and ice, you swim in extremely cold water just to exercise your body, which is called willpower.

I am tired, but because of the thought of being a high school champion in my heart, I refresh myself to read until dawn, which is called willpower.

Just because of a certain thought in the heart, even if you are broken and persevering, this is called willpower.

Willpower is perseverance, patience, and a way to temper oneself and hone oneself through external suffering.

"You can give it a try. Gu Tianfeng decided.

"Pain is the best way to grind," he says. ”

I have to say, this is really perverted, and it can be said that it boosts willpower in an extreme way.

Gu Tianfeng pondered for a moment, left the small courtyard directly, and went straight to the trading house.

In the dead of night, it is the best time to cultivate, and the trading house is deserted, with only a few people coming in and out.

Seeing that the fierce and vicious person came again in the morning, the little attendant instinctively shrunk her neck, but tonight she was on duty, and said with a hard smile: "My lord, is there anything I can do to help you?"

Gu Tianfeng nodded and said lightly: "I need something that can stimulate the pain of the human body, but it can't damage the physical body." ”

This thing is very strange, but, Gu Tianfeng knows, the trading house must have it.

The little waiter breathed a sigh of relief and said with a smile: "Yes, we have an elixir here, called sawgrass, which is crushed and soaked in water, and the flesh is stained with unbearable pain, as if someone has been sawing it on the body with a saw." ”

Gu Tianfeng's eyes lit up, and he said, "Give it to me." ”

The little attendant turned around, and soon came over with a large package of elixir, and said with a smile: "These are enough to make ten barrels of elixir, a total of ten spirit pills." ”

"Hmm. Gu Tianfeng nodded, fortunately, it was very cheap.

Back in the yard, Gu Tianfeng took out the sawtooth grass, which was as sharp as the sawtooth around it, and then began to grind.

It was done in a few moments, and then a bucket of water was fought, and sawgrass was put in, and the clear water suddenly became green and terrifying.

Gu Tianfeng took off his clothes and went in.

"Hmm, why don't you feel it?" he wondered, could it be that the weight was too little?

At this time-

"Uh..." A huge pain instantly spread throughout the body.

The body seemed to be cut by countless saws, life was worse than death, Gu Tianfeng's two delicate eyebrows were twisted together, and he couldn't tell which was the left eyebrow and which was the right eyebrow.

"The body... Gu Tianfeng gritted his teeth and felt a trace of abnormality.

He wanted to raise his hand, but found that because of the severe pain, the body's functions became slow, as if there was a delay, and it was more like a rusty machine, which could not function.

"This ・・・・・" Gu Tianfeng couldn't cry or laugh, "Is this considered self-inflicted?"

However, the pain was so severe that he didn't think about anything else, and every piece of skin on his body was cut by a hacksaw, a pain worse than killing him with a single knife.

"Shinobi !!"

Gu Tianfeng gritted his teeth, simply closed his eyes, and silently endured the pain, only a clear heart was clear, that was his determination.

"Uh..."

Many times, he was pulled back to reality by the pain, and had to endure this inhuman pain, hacksawing the skin, although it was not a real hacksaw, but the pain was accurately transmitted to the brain.

"Hurt・・・・・

Severe pain can make people unconscious, this is human instinct, but Gu Tianfeng insisted that if he passed out and lost consciousness, what was the point of cultivating willpower?

"My heart is immortal, my soul is immortal... As long as I have a breath left・・・・・・"

Gu Tianfeng sat in the barrel, his heart to the sky, and silently endured this pain.

Time is advancing, but Gu Tianfeng is like a year, he is already sweating profusely, and he almost fainted several times.

The night was hazy and poured in through the window.

The barrel is gradually becoming clear again, and the medicinal effect is eroding.

A few hours later, Gu Tianfeng opened his eyes, his gaze was as deep as the starry sky at night, but there was a hint of surprise hidden in it.

"Got through it. As soon as he left the liquid, the pain disappeared instantly, and he moved quickly, quickly put on his clothes, sat cross-legged at the head of the bed, and entered a state of 'inner vision'.

In the soul space, the light is brightened into the day.

"This... The soul fire has actually strengthened a little more. "Gu Tian's style can't help it, a very faint trace, if you really want to compare it, it is even thinner than a hair, and only Gu Tianfeng himself can feel it.

"Great, my assumption is right, the strength of the soul represents the strength of willpower, the stronger the willpower, the more brilliant the soul will become, I actually succeeded・・・・・" The ecstasy in Gu Tianfeng's heart can no longer be described in words.

For a long time, Gu Tianfeng had been passively absorbing the energy emitted by the soul fire and cultivating soul power, but it was very weak, so weak that it was almost invisible.

At this moment, the enhancement of the soul can emit more energy, and the cultivation of soul power will also increase.

"The True Interpretation of the Holy Spirit is my biggest reliance, but I have been suffering from not having enough soul energy to enhance my soul power, with the enhancement of my soul power, I can see more clearly after entering the state of 'inner vision', and my grasp of true power is more accurate, at that time, my cultivation speed will be raised to a higher level. Gu Tianfeng clenched his fists.

The enhancement of soul power will also improve the perception of the external world, which is more conducive to the comprehension of the three realms of martial arts and strength refinement, and even the realm of artistic conception above the 'realm of unity'.

Although the soul energy has only increased slightly, but when it accumulates, the soul power will gradually become majestic, and finally the soul fire will be completely enveloped.

A new common sense made Gu Tianfeng excited, and he simply took out a bag, which contained two thousand Gathering Spirit Pills.

"I wanted to raise three thousand and cultivate again..." Gu Tianfeng said: "Forget it, let's start cultivating tonight, I don't know what the effect will be." ”

He couldn't wait to grab a spirit pill and throw it into his mouth.
