"Warriors' weapons are divided into three grades, namely ordinary weapons, sharp weapons, and divine weapons. Each type is divided into three grades: upper, middle and lower. Among them, ordinary weapons are ordinary weapons, which are mainly distinguished according to their sharpness and sturdiness.

But mortal vessels cannot carry the inner energy."

"Sharp weapons are not only sharper and stronger than ordinary weapons, but they can also carry inner energy and exert the power of warriors above the inner energy realm. The quality mainly depends on the transmission of inner energy and the degree of loss. Low-grade sharp weapons can transmit less than 40% of the inner energy.

In terms of Qi, medium quality can transmit 50 to 70%, and high quality can transmit 80 to 100%."

"As for the divine weapon, it can not only transmit the inner energy 100% without loss, but also increase the power of the inner energy. Not only are the materials used for the divine weapon extremely precious, but they also require a forging master in the innate realm to create them. They are rare in number and generally

Only those who are in the Xiantian realm can hold it."

Yu Guihai talked eloquently and gave a general description of the classification of warrior weapons.

"good."

Yu Renlong nodded in approval, reached out and took out a long knife with a slender blade from the weapon rack and handed it to Yu Guihai.

"This sword is called Xuan Blade. It is a top-grade sharp weapon, no less than the Lengyue sword in my father's hand. Now it belongs to you."

Yu Guihai stretched out his hand to take it, and suddenly felt his hand heavy. He was slightly shocked, it was such a heavy knife.

The blade of this knife is slender and looks light, but it weighs over a hundred kilograms, which shows that the material is special.

However, his cultivation has reached the high level of body training, his body is strong and his strength is endless, so this little weight is nothing to him.

He held the long knife in front of his eyes with one hand, held the handle of the knife in his right hand, and pulled out half of it with a clang.

Half of the black blade appeared in front of you.

He was slightly startled, and then he pulled out the entire blade. He didn't know what material the blade was made of, but it was completely black. Even the blade was pitch black.

No wonder it’s called Xuan Blade!

Whoosh!

Putting the long sword into its sheath, Yu Guihai was overjoyed and said, "Thank you so much, father!"

This knife is black, low-key, non-reflective, and fits his personality very well. He likes it very much.

"You and I, father and son, don't be polite!"

Yu Renlong waved his hand, and then said with a serious face: "With your cultivation level, I shouldn't have given you this sword, but the other mid-to-low-grade sharp weapons are either heavy swords or double swords, which are not suitable for your sword skills. So.

My father gives you this sword."

"But children holding sharp weapons can easily injure themselves. You must be careful when using this knife to avoid injuring yourself."

"I remember, kid!" Yu Guihai said hurriedly.

"That's good! Now come with me to comprehend the Shuiyue Ningfeng Knife!" Yu Renlong nodded and said

"I see!"

After Yu Guihai learned the Shuiyue Ningfeng Sword, he understood why his parents repeatedly emphasized that the power of this sword technique can only be exerted by the inner Qi.

This sword technique uses internal energy to drive the execution. The continuous sword energy is like water and silk, and it is constantly entangled, and even the wind can solidify.

It can make the enemy appear to be in a torrent, unable to control themselves and drifting with the current.

When you can no longer struggle, you can see a round of sword light like a bright moon in the sky, slashing down and taking the enemy's leader.

The name Shuiyue Ningfeng also comes from this.

After understanding this, Yu Guihai no longer paid attention to this sword technique.

He first spent two days upgrading the Thirty-Six Gale Blades to perfection.

After it is perfected, the power of this sword technique greatly increases. When it is used, the sword light around the body flashes, like a ball of sword light and a strong wind sweeping everything, exuding a huge momentum like a strong wind sweeping away fallen leaves, making it difficult for people to have the desire to compete with them.

On this day, midnight came and everything was quiet.

Yu Guihai was alone in his room, sitting on the bed, looking directly at the invisible interface in front of him that no one else could see.

Until the upgrade point suddenly changed to 1.

Then, he reached out and picked up the small white jade bottle placed in front of him, which was the bottle containing Peiyuan Dan.

He wants to break through to refine his internal organs.

He decided to use Peiyuan Pill at this time after some consideration.

Generally speaking, such treasures should be used at the most critical times. It is recognized by ordinary warriors that the most critical level of body training is blood refining and marrow refining, while viscera refining should be placed at the back.

The main reason is that the blood and spinal cord do not contain muscles, so it is difficult for strength to penetrate and is the most difficult to temper. Therefore, it is necessary to use good drugs to assist in increasing the tempering effect.

However, he looked through the inheritance left by his ancestors and mentioned it.

"The brain is protected by bones, but the strength is not high enough. It is difficult for ordinary exercise drugs to reach it. Even the effect of Peiyuan Dan cannot reach the brain. It is better to use more soothing and refreshing drugs for better results."

Of course, this statement is currently not recognized by current martial arts theory. Most martial artists reserve the best physical training drugs for use during marrow refining.

But Yu Guihai is different. He has medical knowledge from his previous life and he agrees with this very much.

Moreover, he believed that the internal organs were the most important part of the physical body. If the internal organs were strong, everything else would become stronger. If the internal organs were weak, the other organs would not be able to become strong.

Therefore, after comparing the two, he decided to use the Peiyuan Pill when refining the internal organs to maximize its effect.

Yu Guihai took the small white jade bottle and took a closer look, then rubbed off the wax seal and pulled out the cork.

A faint scent of medicinal medicine flows into the tip of the nose, and I immediately feel relaxed and happy, and my whole body feels comfortable.

His eyes lit up, he didn't expect this thing to be so magical. It seemed that its efficacy was absolutely extraordinary, and perhaps its body-building effect would not be bad.

He stretched out his hand and poured it down, and a green pill rolled down into his palm, making his hand feel slightly cold.

This projectile is about the size of a red date, green as jade, round and smooth, just like an emerald ball, and looks extraordinary.

"Pei Yuan Dan!"

When Yu Guihai saw the true appearance of Peiyuan Dan, he became even more convinced that this medicine had extraordinary effects. After all, based on its appearance alone, it was by no means comparable to those dark, bitter ordinary medicines.

Without hesitation, he immediately raised his hand and pressed it to his mouth, then swallowed the Peiyuan Pill in one gulp.

Soon, I felt a heat spreading in my belly, as if there was a heater inside, making my whole body warm and comfortable.

"Upgrade the Infinite River Technique!" Yu Guihai muttered silently.

Rumble~

It was like thunder roaring in my mind, and countless scenes of cultivation passed by in circles.

He quickly became familiar and in-depth with the internal organs and the methods of training the internal organs. This was all gained through personal experience during countless hard trainings. It was far more profound than what he had learned on paper from the exercises before.

At the same time, his body also underwent drastic changes. The muscles all over his body were wriggling in waves and constantly contracting inward. Especially the abdominal muscles were twitching rapidly as if they were equipped with small motors.

Judging from the appearance, he was huddled together and shrunk by a full circle.

The powerful energy of Qi and blood is continuously transmitted into the body along with the peristalsis of muscles. Various internal organs are like entering a washing machine equipped with a powerful massager, being continuously rubbed, vibrated, washed and washed.

The powerful medicinal power of Peiyuan Dan turns into a warm current that continuously moisturizes the internal organs, allowing them to quickly recover from wounds and at the same time rapidly strengthen them.
