At the far west from the headquarters, more than a million alliance troops were also in the midst of their assault on the last devil stronghold on this side of the region. This million-strong force was led by one of Emperor Rozwald's generals who was at the pseudo immortal stage.

At this moment, they were besieging a fortress where many devils had already sealed themselves inside. The fortress area itself was truly vast and protected by thick defensive walls.

The barrier that protected the fortress also had the same quality as those used in big cities. It could withstand many attacks from a peak pseudo immortal stage before breaking.

This only showed that the devils in this world truly did not hesitate to spend any resources to make any place they lived in possess strong defenses. These kinds of places must have consumed many resources just to maintain them.

The alliance troops already had support from one interstellar vessel in the upper atmosphere, and it had even fired the beam cannon a few times. However, the barrier currently erected around the fortress still had not shattered.

The general also did not rush things, since the alliance already knew about this information, so that was why they were patient with this war. If the devils did not want to come out of their turtle shell, then they would have to destroy it first even though it would take time. They were going to stay in this world until it was liberated from the devils.

As he observed the erected barrier that they were still trying to break with the combined attacks from several battle formations, he suddenly received an incoming communication through his communication artifact.

After he connected to it and heard the report being delivered, his eyes widened before he looked at the alliance troops.

"All breaker groups, retreat behind the red line, retreat behind the red line! I give the order for all troops to retreat behind the red line!" he shouted, causing many troops to be stunned.

The cultivators in the battle formations that were still attacking the barrier stopped their attacks. They were confused, but they obeyed and retreated. Just like what happened on Emperor Rozwald's battlefield, many were confused by the leader's decision.

However, the moment they saw the rain of swords descending from heaven, they were truly grateful that their leader had ordered the retreat.

If they were caught in the crossfire, there was no way they could withstand it and they would be instantly obliterated by those strikes. They even doubted if their bodies would leave anything behind.

The vast fortress was utterly destroyed without leaving any structure standing. The entire fortress was flattened into rubble. This was truly like a dream, since the strong fortress that had been standing fifteen seconds ago was already gone.

With this attack, they knew that Aldrian the Great had finally come out from his cultivation and joined the battle, and he joined it with a show of great power!

After destroying the fortress, Aldrian did not stop there as he then moved in another direction. He would help the alliance troops who were still engaged in battle with the groups of devils. The alliance troops had almost taken this vast region entirely.

Later that day, thanks to Aldrian, the region finally fell under the alliance forces. The battle that they thought would take another three days at most was finished today.

-----------------------------

Night finally fell on the region where the headquarters was located. The night on the Red Mist Star was much darker than in a normal world, just like any territory that had already fallen into the devils' hands. The red atmosphere and mist prevented the light from other stars from penetrating the surface of the world.

That had been the case across the world for many generations.

However, over the past few days, the headquarters had seen a different sky scenery. The red atmosphere above the city now showed a clear and beautiful night sky. The glimmering stars could be seen clearly from their position, just like on any normal world.

This was something that raised questions among many people here. From the experience of many, the sky should not have cleared this fast even if they had already set up a purification formation. Because of the negative energy that had accumulated for so long, the process of returning the atmosphere to normal could take months.

Moreover, they were in a world where the devils had already lived for a long time.

They did not understand how the negative energy in the city had already returned to normal levels, and they felt as if they were living in a normal world even though not even a week had passed since they landed on this world.

Many looked for the answer, and even Emperor Rozwald wanted to know the reason.

But this was the first time they had experienced something like this, and they still could not find the cause. Many simply gave up looking for the cause and moved on, thanking the heavens for this strange phenomenon.

However, for some people, their thoughts eventually turned toward Aldrian.

They did not know why, but they felt that Aldrian had done something that made this kind of phenomenon possible. They wanted to ask him about it, but he was in cultivation, so they stored their questions in their minds.

For whatever caused this strange phenomenon, they did not care as long as it benefited them.

At this moment, Aldrian was inside the largest tent erected in the headquarters. Beside him were many important figures such as Emperor Rozwald, Prince Ronwell, and the generals of the alliance force. Of course, Baek Jimin, Angelica, Xin Haotian, and the leaders from the Aster Empire were also present.

They had gathered here in a joyous mood to celebrate the successful steps in the mission to take back the Red Mist Star entirely from the devils' hands. Aldrian stood in the middle of the gathered people as he raised a glass of wine in his hand.

"To all of you, the brave warriors who battled the devils with valor, the ones who will be written in history as the warriors involved in this war to cleanse the devils from this world. May the glory always follow us!"

"May the glory always follow us!" the others said in unity before they drank the wine.

After they drank the wine, Emperor Rozwald, who was much closer to Aldrian, spoke to him.

"Your Majesty, with you here, I think it will not take long before the entire Red Mist Star is taken back from the devils. There is already no way those devils have the power to face our combined force, but with Your Majesty joining the battle directly, I think this will be a walk in the park."

The others also agreed as they heard it. Aldrian just smiled and shook his head.

"No, although I might be powerful, I am only one man, and my ability and capability are limited to a certain extent. The real heroes are all of you who have been fighting this past week without me. I am truly sorry I had to unexpectedly cultivate as I received an enlightenment at that moment," he said.

"Ah, that is nothing, Your Majesty. If, at that time, Your Majesty truly received enlightenment, then you must take it. Moments like that do not come often, and if I were in Your Majesty's shoes, I would also have instantly entered seclusion," Emperor Rozwald said.

"Moreover, Your Majesty's opening strike, when you created all of those meteorites, was enough to kill many devils in many places and destroy many of their fortresses and hideouts in the surrounding region. That made it easier for our forces to strike them, and it shortened the time needed for us to take the entire vast region." He added.

"Yes, Your Majesty, we don't mind at all. Your Majesty can take your time to cultivate. Besides, with Your Majesty not joining the battle, we had a chance to fight those devil bastards—something impossible if Your Majesty had joined, because Your Majesty would have already killed all of them in one sweep," one of the generals said in a joking tone, which made the others laugh.

The others also shared their opinions, showing that they had no problem with him not joining the battle earlier.

Aldrian smiled as he nodded to their comments.

"Thank you for your understanding and support. Now that we have already taken back the vast land in this world, the time when this world will finally be free from the devils will not be far off. Let us keep our good work and not let ourselves become arrogant because of our current success. Do not underestimate the devils' cunning nature," he said.

"Yes, Your Majesty!" the others answered in unison.

While the alliance force was in a festive mood, the opposite happened on the devils' side. There were still many places and regions that had not yet been touched by the alliance force because of their limited numbers. However, it was only a matter of time before they reached these places as well.

One such place was a city in a region far from the alliance force. Inside this city, Xarz's right-hand man was staying. He was staying inside one of the mansions where the local devil noble had lived in the past. The leader of the noble family here was also one of the devils who had joined Rulleus to the central star cluster along with many of his men and family members.

So this mansion only had a few devils staying in it at this moment, and he simply used it as his temporary dwelling.

After he escaped from the headquarters, he fled to a nearby city, but then he had to escape again as the alliance force kept pushing them back.

The alliance force's momentum was unstoppable, and the devils continued to lose ground.

This frustrated him because this was the first time he had felt something like this—no, this was the first time the devils here had ever been pushed this far.

At this moment, he was sitting inside his private bedroom, thinking about the current situation when he heard a knock on the door.

"Excuse me, my lord, another report has come."
