As the skeletons continued to deepen, Dong Changsheng found that the passage inside became more and more complex. The underground mining area where he was located seemed to be only a small part, and thousands of skeletons scattered and did not reach the limit here.

If he was not mistaken, the entrance to the ore vein found by Mu Qingshan should be just one of them.

This can also be verbally confirmed from Beitangmu's memory.

After the exploration of the skeletons during this period, the overall distribution of nearby spirit stone veins has emerged in his mind, but it is not consistent with what Beitangmu knows.

Although the terrain inside the Luofeng Secret Realm will change greatly every time it is opened, according to records, the distribution of underground ore veins has not changed much. Otherwise, the secret realm will only be opened for one month, and those who come in will not be able to find the location of the ore veins.

An hour later, Dong Changsheng, who was in the rear, began to move. Now the skeletons have found the general direction rich in the flame spirit stone ore veins, and all the skeletons are concentrating on exploring there.

With the previous exploration of the skeletons, he faced many forks of roads and was no longer confused. He just needed to move straight forward according to his memory.

As we continued to move forward, stones with a size of fists began to appear on the surrounding cave walls, emitting a light red light. They were the lowest-grade flame spirit stones.

However, Dong Changsheng didn't care about these low-grade roasted flame spirit stones. Not to mention Dong Changsheng, even if other people in the secret realm came here, they wouldn't care too much.

Because these low-grade roasted flame spirit stones cannot be preserved in the outside world for more than one month, this is caused by the incomplete rules of the Lingwu World, those people are staring at the medium-grade roasted flame spirit stones that can be preserved for a long time.

As for the top-grade roasted flame spirit stone, it is a rare existence.

Among the mineral veins of Luofeng Secret Realm, low-grade spirit stones are relatively ordinary, medium-grade spirit stones are rare, while high-grade spirit stones are rare.

According to records, only when Luofeng Secret Realm is opened three times on average, someone will find a top-grade Roasted Flame Spirit Stone.

Spirit stones of different grades are not only a difference in energy contained within them, but more importantly, a difference in quality.

Just as Dong Changsheng was running and tidying his thoughts, a noisy squeak suddenly came from the mine road ahead.

When Dong Changsheng heard this, he paused slightly, and then continued to run forward along the middle of the passage.

After a while, a group of rat monsters, which were generally more than one meter long, rushed out of the darkness and hurriedly followed the corners of both sides of the passage. When they passed by Dong Changsheng, they did not show any abnormalities.

These are all spirit-eating mice, which mainly feed on spirit stones. The hair on the surface of the body is extremely tough, which can greatly offset physical and spiritual damage. They have a very sensitive sense of smell, and their limbs and teeth are extremely sharp, and they have a strong desire to attack living creatures.

It is precisely because of this that the spirit stone ore veins are the territory of the spirit-eating rat, and other monsters dare not come in at all.

After walking forward for a while, Dong Changsheng finally saw the figures of the skeletons. These were gathered from other directions and were waiting for Dong Changsheng here.

Seeing this, Dong Changsheng took them into the soul space without stopping.

At this moment, he suddenly sensed that a skeleton team was completely dead in an instant, and there were no suspicious targets in his sight.

The direction the skeleton team explored was exactly the most abundant direction of the Rotten Flame Spirit Stone, so he accelerated his pace while ordering other skeletons to gather there.

...

Yu Kongqing carefully checked the pile of broken bones on the ground. Seeing that they were indeed dead, he waved to the darkness. Immediately, more than a dozen figures rushed out of the darkness.

These people are all descendants of Yu Kongqing, and they are from the Yu family. After entering the secret realm, they are not far apart. They are connected with each other through family secret techniques and finally gather together.

They and Mu Qingshan and others did not enter the underground spirit stone vein from the same place, but they met in the cave in front.

Of course, it goes without saying that the force of both sides is not at the same level. In order to reduce competitors, Yu Kongqing killed them all in an instant.

Yu Kongqing and others were really lucky. They only took less than a day to find this place and walked a distance. There is a high probability that the medium-grade roasted flame spirit stone would be found inside.

However, just as they were full of joy and were about to receive the harvest, a team of skeletons suddenly came here.

This immediately reminded them of Dong Changsheng, who was also a skeleton. Although Yu Kongqing was extremely afraid of Dong Changsheng, he was unwilling to give up the spirit stones that were within his reach, so he took the risk of killing all of these skeletons.

He hopes that Dong Changsheng will not find these skeletons dead in a short period of time, or at least not find out who will die at the hands of those skeletons.

However, since most of the skeletons were exploring nearby, Dong Changsheng just ordered them to rush to the place where the skeletons died, and immediately three teams of skeletons approached here.

I happened to see Yu Kongqing and others. Although they were killed instantly again, Dong Changsheng had already recognized Yu Kongqing.

Yu Kongqing glanced at the broken bones on the ground, flashed to the next generation, and said in a deep voice: "Come with me."

After saying that, he ran straight forward. The disciples did not hesitate at all and immediately followed closely.

Just after they left, teams of skeletons also came here, and then scattered to search for their traces.

...

Two days later, Yu Kongqing and others came to a cave.

The cave was filled with spirit stones that were fused into the walls, and most of these spirit stones were low-grade flame spirit stones, and occasionally a few medium-grade ones.

However, Yu Kongqing had no intention of digging out these spirit stones now. He glanced at everyone behind him and found that they were all gasping for breath. Several people were still wearing some scars on their bodies. After thinking for a while, he said, "Take a break for a while."

Everyone behind him immediately sat down on the spot when they heard this and seized the time to recover their energy.

During this period, no matter where they hide, they will always be found by the skeletons. Although the skeletons are of average strength, the owner behind them is not something they can provoke, so they can only avoid them as much as possible.

However, it was raining all night long. Not long ago, they encountered a group of spirit-eating mice. Although no one died under Yu Kongqing's protection, some people were still injured.

Afterwards, they fled in a hurry under the pursuit of the spirit-eating rat group and the skeleton group, and did not dare to stop all the way, for fear of being entangled, which would attract Dong Changsheng.

Yu Kongqing felt the messy and strong energy position of the cave, and breathed a sigh of relief, thinking: "They shouldn't be able to find this place in a short period of time."

However, at this moment, a skeleton appeared at the entrance of the cave.

The moment Yu Kongqing saw this skeleton, he immediately shouted: "Beware."

The people beside him who had just sat down immediately stood up, tightened all over and prepared for the battle, and looked at the entrance of the cave along Yu Kongqing's gaze.

The skeleton walked into the cave step by step, and the momentum on his body continued to increase. Everyone felt that a huge rock was pressing on their hearts, and their bodies began to tremble involuntarily.

In the dead cave, the heavy breathing sounds of the people were clearly visible.
