Jiang Ming's heart moved, and he pretended to know nothing and cooperated. "Why?"

The black sword hurriedly explained, "The fog here can replenish my energy. It's a rare and wondrous thing. Not only can it assist in martial arts cultivation, but it also has a terrifying weakening effect on immortal cultivators. If they're not a Foundation Establishment Realm martial artist, even a Golden Core Realm cultivator will suffer if they come into contact with it!"

"Oh? I tried to collect it before, but I didn't succeed!" Jiang Ming said lightly. However, he was surprised. Previously, he only found that this fog could weaken immortal cultivators. However, he had not found out that it had an auxiliary effect on martial artists.

"As expected of the black sword. Even if it's irritating, its knowledge is extraordinary." Jiang Ming thought to himself, "Maybe taking this black sword will really bring me some unexpected joy. Of course, the premise is that this psychopath doesn't cause me any trouble."

"Only by using a special material as a medium and using a specific technique can the fog here be absorbed. For example, my body!" the black sword said arrogantly, displaying its utility. "I can collect it for you. In the future, when you're cultivating or facing an enemy, you can release it!"

"Oh, there's a technique? Why don't you teach me!"

"I'm not bragging. However, this technique has extremely strict requirements for the medium. Fellow cultivator, you definitely don't have it on you." The black sword swung its blade repeatedly.

Jiang Ming sighed. "You're being mean to me."

The black sword was stunned. Finally, the black sword gritted his teeth and passed on a nameless technique to Jiang Ming.

"This is a technique that specializes in the circulation of blood Qi. It can collect and refine all kinds of strange forces in the world that are beneficial to martial artists. However, it needs to be circulated with special materials, such as what my body is made of," the black sword said faintly. Obviously, this technique was extremely precious. It had described its value to Jiang Ming to prove its sincerity.

Jiang Ming silently recited this technique. However, he was extremely shocked in his heart.

He had seen a lot of martial arts cultivation techniques since he started cultivating. However, most of them were methods to improve blood Qi and simply burst out the power of blood Qi. Compared to the mysterious techniques of immortal cultivators, they were rather crude.

And this nameless technique was the first martial arts technique that he had ever seen that could be considered exquisite. It could absorb strange powers and refine them into the body. It was much more brilliant than any other technique.

"It seems that the era of martial arts of the past was glorious."

Jiang Ming thought of the first primitive martial artist who fought against the heavenly tribulation with his body. That should be the first instance of martial arts.

"The physical body is the foundation of a person. Everything is rooted in the physical body. Perhaps the end of the martial arts path is far beyond what ordinary people can imagine!"

Jiang Ming thought of the Hundred Tribulations Sacred Body again. Was it an exploration of the end of martial arts in an ancient civilization?

"Fellow cultivator, how is it? Just let me do it!" the black sword said eagerly, wanting to show off his ability.

"Ah? Don't panic, I happen to have something here, let's try it first."

Jiang Ming laughed and took out a black thing.

The black sword, which was jumping up and down, was instantly stunned.
