One must know that the black stones he used were of the seventh grade at worst. Even members of the Jinxuan macaque clan would not be willing to use such high-quality black stones in their daily practice, let alone other forces.

The highest quality of black stones is rank nine, and rank nine black stones are strategic resources, and no one would use rank nine black stones in daily practice.

Although the eighth-rank black stone is not as precious as the ninth-rank black stone, it is still very difficult to obtain. Warriors usually treasure the eighth-rank black stone. After losing a lot of energy in the battle, they will use the eighth-rank black stone when they need to use the black stone to replenish it.

And generally it is the most urgent, when life and death are at stake, the precious eighth-grade black stone will be used.

This is still a martial artist of the Jinxuan Macaque Clan. If it is a human warrior, even if it is a strong beast, most of them do not have eighth-grade black stones, let alone use eighth-grade black stones.

Even in life-and-death battles, it would be very good to have seventh-grade black stones for use. Of course, one would not use seventh-grade black stones for normal practice, but some low-quality black stones.

It is a very extravagant thing to use the seventh-grade black stone to cultivate, even for the members of the Jinxuan Macaque Clan.

Qin Ming did not hesitate to use the seventh-grade black stone to cultivate. Logically speaking, the speed of cultivation should be very fast, but compared with the golden energy, it is still much slower.

"Even if you use a ninth-grade black stone, the cultivation speed cannot surpass the golden energy. It seems that the golden energy is more precious than I imagined. I must cherish it." Qin Ming sighed.

There is a ninth-grade black stone in his interspatial ring, but even he is reluctant to use the precious ninth-grade black stone for cultivation.

Most importantly, Qin Ming felt that even if he used the precious ninth-grade black stone for cultivation, it was far inferior to golden energy.

Knowing the preciousness of golden energy, Qin Ming became even more precious about golden energy, and only hoped that the space in his mind could absorb more golden energy.

In this way, Qin Ming quietly practiced in the room, and after the practice was over, he would start alchemy.

He didn't know how long he would stay in Lingyun Cave. Usually he didn't have time to refine alchemy, but now he just needed to heal his injuries, so he refined some more pills.

In this way, he can just do other things in Lingyun Cave, and there is no need for alchemy at all.

Even if he has no way to climb up, he can still take all these refined beast-level enlightenment pills to Qincheng and sell them, so as to increase his popularity on behalf of Qincheng.

Such a high-quality beast-level comprehension pill may have never appeared in the entire Jinxuan macaque family. Once such a grade of pill appears on the market, it will definitely be snapped up by warriors.

And it will also attract a large number of masters to Qincheng, and the stronger the warriors, the more wealth they have, so Qincheng can earn more black stones.

Qin Ming didn't know that a war was about to break out outside, and once the war started, Qin City, which was on the outskirts of the Jinxuan Macaque Clan, would inevitably be abandoned.

Therefore, it is obviously unrealistic to sell these high-quality pills in Qin City.

However, the supply of beast-level enlightenment pills is in short supply, and these pills are of extremely high quality, even if they are not sold in Qin City, they will not be sold at a relatively high price in any human city.

Especially when a war is about to break out, all warriors seem to have gone crazy, improving their strength in various ways.
