Gu Bai could feel that the concentration of spiritual energy in front of him was getting higher and higher. Now he could even see some spiritual water gathering in some small pits, which proved that he must be very close to the inner city.

Gu Bai knew very well that almost all the powerful people in Dongju City lived in the inner city. Although Gu Bai was fully prepared at this time, and he was now nearly fifty meters underground, and there were also traces of blood on his body.

There was no power fluctuation coming out, but Gu Bai couldn't cover up the sound. If someone really found out, there was nothing Gu Bai could do, so now he could only try to reduce the sound as much as possible.

Gu Bai was like an insect, moving his body bit by bit underground. In fact, at this time, there were already many high-purity spirit stones around Gu Bai, but Gu Bai was not tempted by this little bit.

Attraction, instead of approaching these things, continued to shuttle underground.

On those spirit stone veins, Aoki Hunter's roots are very lush, and Gu Bai can feel that these things can't be cut off easily, and Gu Bai doesn't want to make such a big one now.

Dongjing, if you are exposed now, all your previous efforts will really be wasted.

Continuing to crawl forward, time has completely stopped for Gu Bai. He no longer knows how long he has been down. Anyway, Gu Bai is mentally tense now. As long as he feels something is wrong, he will stop immediately.

, stopped breathing, and waited for the feeling to disappear before he would move on.

He didn't know how long he had been crawling. Anyway, just when Gu Bai couldn't stand it anymore, he suddenly felt that his body was empty. Gu Bai was shocked and grabbed the walls on both sides.

Just below Gu Bai, a tunnel actually appeared.

When he saw this thing, Gu Bai was immediately overjoyed. He knew exactly what it was. It was a mine tunnel. In other words, where he was now was where people from Dongju City usually mined.

It's getting brighter and brighter here.

The spirit stone veins in the ancient city are also constantly being consumed. They are not sealed and not used at all. Otherwise, the cultivators in the ancient city will not have the resources to show off.

When he got here, Gu Bai became even more careful. This place was very clean, which meant that people often came to this mine. Just when Gu Bai was thinking this, Gu Bai's ears moved and he heard some subtle sounds. This

The sound was very familiar to Gu Bai. It was the sound of footsteps, possibly from miners or patrolling soldiers. However, when he heard this sound, Gu Bai became a little excited, which meant that he had really entered the enemy's lair.

"Haha, this time I'm really awesome!"

Gu Bai suppressed the excitement in his heart, squeezed into the tunnel very carefully, and then fell down from the tunnel. There were still many roots here, but there was not much movement.

After landing on the ground, Gu Bai immediately felt a lot more at ease. Standing in the tunnel, Gu Bai did not directly start to explore the surroundings. He also eliminated the aura around him to prevent others from discovering clues. He wanted to make this place look like it had never been there before.

It's like no one else has been here.

After all traces of laughter were gone, Gu Bai started to

Move forward point by point.

However, after walking a few steps, Gu Bai felt his heartbeat speed up.

You can see countless spiritual energy embedded around this tunnel. Of course, this is just a little bit. Inside the tunnel, there are a large number of spiritual stones stacked together. Although the purity of these spiritual stones is not very high,

Gu Bai discovered some unexpected information on these spiritual stones.

These spiritual stones are not simply piled together, but each spiritual stone has been cut open, and the spiritual energy inside is overflowing.

"This can't be..."

When Gu Bai saw this scene, a thought suddenly came to his mind, and he had his own guess.

These spiritual stones do not look like they have just been mined, but have been unearthed for a while. Maybe these are the spiritual stones that those people took to the store to exchange, and after these low-purity spiritual stones were recovered

, so everything was moved here.

The spiritual energy in this spiritual stone vein is extremely abundant. Under the influence of Aoki Kari, the spiritual energy in these spiritual stones is now completely absorbed and transformed into pure spiritual energy, which is fed back to the spiritual stone vein and Aoki Kari. Finally, the spiritual stone

After the spiritual energy in the mineral veins becomes rich, the spiritual energy will be re-gathered into these spiritual stones that have become empty shells. After being nourished, these spiritual stones will transform into pure spiritual stones.

"That's fine too!"

Gu Bai was stunned when he thought of this. He was completely confused. It seems that Dongju City has found a way to use the spirit stone mine sustainably. I have to say that this method is indeed quite clever and easy to operate.

In fact, there are some difficulties. The most fundamental thing is to rely on Aoki Kari. After all, it is not an easy task to purify so many spiritual stones at once.

No wonder there is an endless supply of spiritual stones in this ancient city. It seems that the people in these restricted areas are not without brains, and they can still come up with such a method.

In addition to Aoki Kari's help, this is actually the ancient city's own plan. It is estimated that the ancient city has already made regulations. For example, once the mineral veins outside the ancient city are found, they will be dug out directly.

Spiritual stone veins are only high-quality spiritual stones with abundant spiritual energy. As for low-quality spiritual stones, they only need a large amount of spiritual energy from low-quality spiritual stones to be cultivated, and they can become high-quality spiritual stones after a period of time.

The tunnel where Gu Bai is now is filled with such low-quality spirit stones, so the people who come here should be patrol soldiers. Maybe this was also the place where high-quality spirit stones were produced back then, but most of the high-quality spirit stones were produced here.

The stones have all been dug out, and now it has become a storage place for low-quality spiritual stones. If he had seen so many spiritual stones before, Gu Bai would not have cared about the spiritual energy concentration at all, and would have put them all away first.

.

But this time, Gu Bai was indifferent, because it was not worth his risk to try for these spiritual stones. If something happened, all his efforts would be wasted.

Continuing to walk forward for a while, Gu Bai saw another large piece of spiritual stone. This spiritual stone was different from the others. He felt that the concentration of spiritual energy in this spiritual stone was very high, and it could at least be used for cultivation.

There is no problem. Now Gu Bai can't help but be tempted. A spiritual stone the size of his head is worth it.

Go on an adventure yourself.

Thinking of this, Gu Bai slowly knelt down and took a look at the roots near the spirit stone. After hesitating for a while, he finally made up his mind, and with quick eyes and quick hands, he directly put the spirit stone into the ring.

Fortunately, there was no movement at all.

When Gu Bai saw this situation, he finally couldn't help but breathe a sigh of relief. It seemed that these things would only be activated when certain conditions were met. For example, Gu Bai's condition was not enough to make the thing move.

Maybe this thing didn't feel the power aura from Gu Bai's body at all, or maybe for such a huge spirit stone vein, the loss of a spirit stone was not a big deal, and Aoki Shou didn't care at all.

"Haha, no wonder there is a strong man of the Ninth Path like Aoki Kari. Soldiers are still needed to patrol here. If we had relied on Aoki Kari's precautions, the spirit stone veins would probably be half empty by now!"

After continuing to walk for a while, Gu Bai frowned and leaned his ear against the wall. He seemed to have heard a sound just now, but the sound was very weak and he could not hear it clearly. Gu Bai wanted to confirm again.

At this time, the surrounding sounds were transmitted through the walls, and Gu Bai could clearly hear the footsteps. In addition to the footsteps, there were also whispers.

"The preparations for the opening of the spiritual pool have been completed. The two of us should prepare well. Then we will find a place closer and wait for the spiritual energy to explode. We may have a chance to attack the fifth path!"

One of them said very expectantly.

"Haha, we can think about it. Our talents are not very good. It is not easy to cultivate to the fourth level. Breaking through to the fifth level is a bit difficult, unless the two of us can practice directly next to the spiritual pool.

, otherwise, there is no chance, but with our

How can we have the opportunity to practice inside with our identities? You must know that the most central location must belong to the Holy Lord and the Lord Tutong. Only the elders can enter the places further outside. We can only

Just hang around outside and you can’t go in!”

Another person sighed and said, but he was also very optimistic and didn't feel anything disappointing.

"Then...it will be better than our usual self-cultivation. If we can reach the fifth-level realm, the treatment will definitely be completely different from the current one. Then we will have the opportunity to go to higher-quality mines to practice.

, this cultivation speed must be very fast, maybe we can also hit the realm of elders!"

Another person said very reluctantly.

"Well... what you said makes some sense, but I do think that we don't have to go to the fifth level. You also know that this time we fought against the human race over there, and the leader of the realm suffered heavy losses. Our king

Maybe in order to replenish our strength, we may be allowed to enter those high-quality mines to practice in advance!"

The man said in a deep voice.

"Really?"

The other person was immediately delighted, this was really good news.

"It's almost like this, and many people are spreading it like this now!"

"..."
