However, this demon had always signed a contract with the Wings Clan on its own accord in the past. It was unlike this time where it did not even have a body. How could he be a match for Li Yuanqing, a fifth-grade Grotto-Heaven Realm expert? He had just rushed over when he was slapped to death by Li Yuanqing.

The Demon Subduing Palm was the nemesis of this demon. Killing him was simply too easy.

Li Yuanqing clapped his hands and looked at the entrance of the hole with extreme ease, hoping that another demon would come out.

Unfortunately, he did not see any after waiting for a long time.

However, Li Yuanqing was not worried. He sealed the hole and came back the next day. He opened the hole and continued to wait.

This time, Li Yuanqing waited for an entire day but no demons rushed out. He could only seal the catacomb in disappointment at night. He did not get anything good today.

On the third day, Li Yuanqing unlocked the seal on the entrance of the catacomb again. This time, he was lucky.

Soon, a voice sounded in Li Yuanqing’s mind.

[Host, do you want to sign in at the entrance of the catacombs?]

Here it comes. Li Yuanqing finally figured it out. If a demon appeared from the entrance of the catacombs, he would be able to sign in again.

If no demon came out, he would not be able to sign in even if he guarded the entrance of this catacomb.

“Sign in!”

Soon, Li Yuanqing signed in again. This time, he took another hundred Demon Slayer Swords. He had two hundred Demon Slaying Swords on his hands now!

The effect of using it to nurture and set up a sword formation could not be better.

As expected, when Li Yuanqing obtained the Demon Slayer Sword, he saw another demon rushing out of the catacomb. This time, it was a fourth-grade Grotto-Heaven realm demon.

This was the first time Li Yuanqing had encountered a demon with such a high realm after his advancement. It was an excellent opportunity for him to practice.

As expected, a fourth-grade Grotto-Heaven Realm expert was not so easy to deal with. Li Yuanqing used the Demon Subduing Palm to hit him, but it was useless as he dodged it.

Even if he threw the Saint Extermination Stone over, he could only control this demon for a second. As expected, the stronger the opponent, the weaker the control of the Saint Extermination Stone.

His Saint Extermination Stone could at most stall a fourth-grade Grotto-Heaven Realm expert for a second.

Li Yuanqing only had one second to kill this fourth-grade Grotto-Heaven Realm demon. Therefore, in the next moment, when Li Yuanqing threw out the Saint Extermination Stone, he struck out with his palm, and the Clear Sky Sword stabbed out!

One second. Just one second. Li Yuanqing used his palm, sword, and the Saint Extermination Stone. In order to prevent this demon from being too powerful, Li Yuanqing planned to use the Sand Escape Technique to retreat a few steps before sealing the hole!

Of course, Li Yuanqing could not let go of the demon that had appeared from the catacombs. Otherwise, a fourth-grade Grotto-Heaven realm demon was enough to destroy the Northern Kingdom.

Therefore, for the sake of caution, Li Yuanqing even set up the Heavenly Cycle Demon Extinguishing Array at the periphery. This was to trap the thing that emerged from the catacombs.

After all, there were too many unknown things in the catacomb for him. There were more risks than benefits.

It was better to be cautious!

This demon had just rushed out of the catacomb. Although it had the strength of a fourth-grade Grotto-Heaven Realm expert, it could not withstand Li Yuanqing’s moves. The Saint Extermination Stone controlled its movements, then the Demon Subduing Palm and the Clear Sky Sword hit him!

Therefore, a second later, the demon’s soul had already dissipated. He was extremely aggrieved when he died. Who was this? Why was he so strong?

He was too unlucky!

On the other side of the catacombs, countless demons were nervously waiting for news. The person who had gone out was an expert. Even if it was only a wisp of his soul, he had the strength of a fourth-grade Grotto-Heaven Realm expert.

Didn’t the spiritual energy in the human world be scarce and that even first-grade Martial Saints were rare? When did a fourth-grade Grotto-Heaven Realm martial artist go over and not come back?

“The soul lamp is extinguished. He’s dead. He’s dead. His soul has dissipated!” A terrified voice sounded. The originally chattering voices suddenly became silent!

All the demons in the cavern looked at the flickering and unstable exit in horror. However, none of them dared to move. Not only did they not dare to move, but they were also retreating!

To them, going to the human world was to live a better life and snatch more resources, not to die after experiencing all kinds of dangers!

“Run!”

These demons retreated in unison. Moreover, in the hearts of these demons, they regarded the entrance of Catacomb No. 1 as the most dangerous place.

Although this place was the first to loosen up and a few companions went out first, the soul lamps of the companions had been extinguished, which meant that they were all dead!

This place was a forbidden area for demons like them. No one was willing to try it unless they had no choice.

In any case, this was not the only exit of the catacombs. It was too difficult to get out of the Catacomb No. 1. Almost no one was alive.

At least some of their companions could escape from the other catacombs. Furthermore, the ratio was not low. If there was a place where they could go to the human world alive, why would they fight to the death here?

More and more demons had this thought. Therefore, Li Yuanqing opened the seal and waited for the demons below to come up. He had actually waited for a few days, but none of the demons were willing to come up.

In the end, there was one who was not afraid of death. The strongest among these demons, a fifth-grade Grotto-Heaven expert, was pushed out. After being sent up, the remaining demons waited there uniformly.

If this expert could survive this time, they would also think of a way to rush over. After all, the temptation of the human world was still very great!

However, the soul lamp of the fifth-grade Grotto-Heaven realm expert went out not long after. This made the demons who were waiting for the news gasp in surprise!

This was terrifying. All the demons were terrified.

Catacomb No. 1 was really too dangerous. All the experts who went out had died. How dangerous would it be up there?! This was not an exit. This was a place to die!

These demons were terrified and rushed elsewhere. In any case, they could not come to Catacomb No. 1 anymore. It was too dangerous. This was a place to die! Moreover, one could not leave the entrance of this catacomb at any time. There was also a specific time. There were only two or three times every year to rush out when it was loose!

However, no one was willing to try such a suicidal opportunity!

It was too terrifying. It was really too terrifying. This was not the only exit in the catacombs. They had heard that their companions had escaped from other exits. It was much safer than here!

Li Yuanqing, who had been guarding the entrance of the catacomb for several days without encountering a single demon, finally sighed and quickly sealed the entrance!

This place was dangerous!
