The medium-grade spirit stone contains nearly a hundred times more spiritual energy than the low-grade spirit stone, but even so, after putting it in the black disc, it was consumed after only a few minutes of support.

Unlike just now, the white light released by the black disc after the medium-grade spirit stone was installed was a little richer than it was just now, but Tang Han still did not understand what the white light had.

The third time, he replaced the black disc with 12 top-grade spirit stones. The result was similar to the moment. Except for the white light emitted by the black disc, he still only persisted for four or five minutes and disappeared into the air.

What is this guy? He has too much appetite? The 12 top-grade spirit stones are enough for a ground-level warrior to practice for a month. Unexpectedly, they were consumed so quickly, which made Tang Han really a little painful.

However, this confused him again. It is said that after the black disc consumes so much spiritual energy, it should play a huge role, but he has not yet realized what the white light has.

"Little thing, do you understand? What the hell is going on?"

Tang Han asked the Spirit-Devouring.

The Spirit Devouring said, "I didn't understand it, but generally speaking, magic weapons only have four major functions: attack, defense, healing, and cultivation. Now, the white light emitted by the black disc does not have any attack or defense functions. You can try healing and cultivation, it should be in these two directions."

Tang Han felt that the Spirit-Devouring said something reasonable, so he took out the Dragon Slaying Dagger and gently cut a bloody mouth on his hand, and then used 12 top-grade spirit stones to activate the black disc.

As a result, he found that the white light emitted from the black disc had no effect on the wound on his hand. It seemed that its function was not to heal the wound, but it should be the last effect, and it must be of great help to practice.

However, the black disc can only be activated for four or five minutes at a time. This time is too short. Before he can enter the state of meditation, the spirit stones have been consumed.

After thinking about it, Tang Han took out hundreds of top-grade spirit stones at one time and then carved a magic circle that automatically supplied spirit stones to the black disc, so that it could last for a period of time.

Tang Han suddenly thought of the four Tianxin Grass seeds he got, and felt that it would be a pity if the spirit stone was used up like this. He took a flower pot from outside, planted the four seeds in the flower pot, and placed it in the middle of the pile of top-grade spirit stones.

The seeds of Tianxin Grass have extremely high requirements for growth conditions. They need to provide a large amount of spiritual energy when germinated. This is also the reason why the seeds of these four Tianxin Grass are preserved intact.

After doing all this, Tang Han sat cross-legged next to the spirit stone and then activated the black disc again.

When the white light emitted from the black disc shone on him, Tang Han began to hold his breath and enter a state of cultivation.

Finally, he discovered some benefits of illuminating white light. Under the illumination of white light, his mentality was extremely peaceful, and he entered a state of emptiness and light in almost the blink of an eye.

Xuantian's true energy was slowly circulating in Tang Han's body. This time he entered into a very deep meditation, and I don't know how long it took after his practice.

Suddenly, a light click came into Tang Han's ears, awakening him from the state of meditation.

He opened his eyes and saw that the hundreds of top-grade spirit stones that were originally piled up beside him had disappeared. The sound of the bang just now was that the black disc had consumed all the spirit stones and fell back in front of him.

Tang Han sighed in his heart. This guy consumed too much spirit stones. If so many top-grade spirit stones were used for cultivation, it would be enough for an annual use for ordinary people.

Is it effective after giving so much? Tang Han closed his eyes again and carefully experienced the changes in his body.

However, after checking, he found that the true qi in his body did not change much, which was basically the same as his usual practice effect. In other words, this kind of white light illumination did not help him in his practice, except to calm his mind.

Tang Han couldn't help but frown. If this black disc had only this effect, it would be really sorry for the spirit stones he had consumed.

At this moment, a faint fragrance surged into his nostrils. Tang Han turned his head and saw that it was the four seeds of Tianxin Grass he placed in the middle of the spirit stone that had sprouted. At this time, it had turned into about an inch of green seedlings, looking green and lovely.

The fragrance of Tianxin Grass is really special. It was only a little bigger just now, and the fragrance emitted was extremely strong.

The Tianxin grass has sprouted. How long have I been practicing? Tang Han couldn't help but be shocked.

According to the records in the inheritance, it usually takes about three days for Tianxin grass to sprout. Has it been three days since I just entered into meditation?

He savored it carefully again. According to his previous practice experience, the time for entering meditation should be about three days this time.

If this is a bit troublesome, he originally promised Nalan Qianqian to treat the Wolf Warrior this weekend. When he was practicing, it was 2:00 a.m. on Thursday evening. If it had been three days, it should have been Monday now.

Tang Han hurriedly took out his phone to check the time, but he was surprised to find that the time of the phone showed that it was 8:30 am on Friday.

How is it possible? Is the phone broken?

If the time is displayed according to the mobile phone, about six hours have passed. But if it is really six hours, it is impossible for Tianxin Grass to sprout, and Tang Han himself feels that the practice just now should be about three days.

He calmed down and thought about it seriously. It might have been only six hours, because the pile of spirit stones he piled up was about six or seven hours at the rate of consumption of the black disc, and it was absolutely impossible to supply the black disc for three days.

This is strange. Although the Tianxin Grass is placed in the middle of the spirit stone, it is absolutely impossible for it to sprout in six hours. And I really feel that after three days, what's going on?

Suddenly, Tang Han's heart moved, and he shouted in ecstasy: "I understand, I finally understand."

In his mind, everything that just happened was instantly integrated. No wonder this black disc had the word "time" written on it. It turned out that its effect was not offensive defense, nor was it healing and practice, but could change the changes of time and turn the flow of years. This is the true meaning of time.

In other words, after the spirit stone starts the black disc, the flow rate of time will be increased several times within the white light exposure range.

He roughly calculated that the 6 hours and 3 days of 72 hours increased by 12 times, which means that his cultivation speed under the black disc was illuminated by 12 times compared to his usual practice.

This discovery made Tang Han ecstatic. It seemed that this black disc was worthy of being a magical weapon and could actually change the changes of time.

Generally speaking, whether it is a magic weapon or a magic weapon, it is extremely rare and rare treasure that can change time. It seems that he really found the treasure this time.
