While Zhou Yan took this opportunity to slowly deal with the demon leader.
"Damn it!" At this moment, the demon leader also realized that the situation was not good. Although he was a strong individual at the Demon King level, he had not yet broken through to the Demon Emperor realm. Therefore, he did not believe he was Zhou Yan's match.
So when Zhou Yan began to attack him, the demon leader knew that if this continued, he would be in great danger. Most importantly, he had discovered that all the other demon troops outside the city had been annihilated.
"Run!" At this moment, the demon leader saw Zhou Yan preparing to flee. But how could he escape? Fleeing under Zhou Yan's nose was simply courting death.
Zhou Yan directly pierced the demon's chest with his sword. The demon immediately fell into a pool of blood, and then his corpse turned into a pile of flying ashes and dissipated into the air.
After dealing with the demon leader, Zhou Yan's guard detachment returned to his side, and the demon soldiers outside the city had also been cleared out.
Zhou Yan then led his troops back to his territory. Upon returning, Zhou Yan immediately announced that he would hold a celebration to reward his troops.
Of course, Zhou Yan's aim was to attract more people to join his army through the celebration, so that his plan could be carried out smoothly.
Zhou Yan's celebration was also very grand. Not only did the people within Zhou Yan's territory participate, but also people from surrounding villages came. Many residents from nearby villages even came to join the fun, hoping to join Zhou Yan's army through this feast. Because since Zhou Yan's previous celebration, they had already known that following Zhou Yan was much safer than staying in their villages.
This celebration was held under Zhou Yan's instruction, so it was very grand. Not only humans were celebrating, but also monsters. Zhou Yan invited many monsters to participate in the celebration. Since there were a large number of these monsters, the celebration was a grand spectacle.
Zhou Yan paid a huge price for this celebration, which was intended to attract demon troops.
Zhou Yan dared to do this because he believed that the celebration would bring greater fame to his army and secure more resources for himself.
The celebration was a great success. During the celebration, Zhou Yan also took the opportunity to win over a group of demon soldiers. Of course, these soldiers were not real soldiers, but were sent by the demons to monitor humans.
During these few days, these demon soldiers began to suspect Zhou Yan's army. This was because they found that Zhou Yan's army had not encountered any danger during this period and was constantly expanding its forces. This made the demon soldiers suspect whether Zhou Yan's army had defected to other forces.
Therefore, these demon soldiers had been secretly observing Zhou Yan's army during these days, but they could not discover anything, which made the demon soldiers very puzzled.
During this celebration, the wisdom displayed by Zhou Yan also made the demon soldiers extremely wary. Especially after the demon soldiers saw Zhou Yan's terrifying strength at the celebration, they became even more fearful of him.
So, during these few days, these demon soldiers became much more well-behaved. This way, even if Zhou Yan's army didn't harass the demons, the demons would not have time to attack Zhou Yan's city.
On the second day after the celebration, Zhou Yan once again assembled his troops, preparing to attack the demon cities. This time, Zhou Yan intended to thoroughly subdue these demons.
On the third day, Zhou Yan personally led his troops to attack these demon towns.
"Big Brother, there are many ore deposits in this region." At this moment, a system prompt sounded in Zhou Yan's mind.
"En?" Zhou Yan became excited when he heard this prompt.
It turned out that just now, the system had transmitted a map to Zhou Yan, marking many ore deposits, all of which were minerals that Zhou Yan needed.
Zhou Yan was very happy when he saw this map, because these minerals were enough for Zhou Yan to forge many demon cores, which would make his army stronger and stronger.
"Let's go, we'll go and seize these ores. These things are very valuable," Zhou Yan said with a smile to the surrounding guards, and then led the soldiers towards a demon city.
"Who goes there, stop!" At this moment, a group of demons on horseback from afar charged towards Zhou Yan and his group.
"Kill!" At this moment, Zhou Yan let out a cold snort, then took the lead in charging, and the surrounding guards followed closely behind Zhou Yan.
Zhou Yan and his group were very fast. Before the demon soldiers could react, they were all killed.
"How have these humans become so powerful?" on a distant mountain peak, a hidden dark figure murmured. He was the leader of the black-robed demons who had brought his troops out to investigate Zhou Yan's true strength.
"My Lord, why are you here?" At this moment, another black-clothed demon rushed over and said.
"I am here to observe these humans. I did not expect their strength to grow so rapidly. It seems we must eliminate these humans, otherwise, if they become powerful, we will be in trouble," the black-robed demon leader said after a moment of silence.
"My Lord, if that is the case, let us go and help eliminate this Zhou Yan now. Their strength is too great, and our soldiers are suppressed to the point where they cannot hold their heads up," the other demon said.
"I wish I could, but recently my cultivation has encountered problems, and I cannot leave this place for the time being," the demon leader said with a frown.
The key to his recent breakthrough lay in the improvement of his state of mind. As long as his state of mind improved, he could continue to advance.
However, what the black-robed demon leader did not know was that the improvement of his state of mind had already failed.
