The Witcher: Son of the Planes.

Polit led the wizard army to the base on the Sutters River. After only one day's rest, he reached an agreement with the demon leader here. The slave army would launch the attack as the vanguard, followed by the demon army, and the wizard army and the upper demons were behind.

The tactics are simple and crude, but it works.

The Cambrian City Guard phalanx where Colin was located stood together with the city guards of other cities in the Dia Kingdom and were jointly responsible for the defense of the lower section of the river.

In the past, Colin always launched attacks from behind the slave army. Now, seeing the slave army attacking like a tide, he discovered from another perspective the horror of the wizarding world's way of doing things.

Various slave creatures from multiple dimensions have lost their basic thinking except for the bloodthirsty killing factor and extreme hunger. In their eyes, the only thing they need to consider is tearing everything in front of them to pieces.

Faced with the familiar scene from the past, Colin had no time to express his feelings. He and Hathaway had to be careful not to use wizard methods at will, or even if they did, they had to pay attention to the methods and try to choose those with less chance of exposure.

Fortunately, Colin still had the foundation of his knight training. Although his physical fitness had declined due to the last promotion, his data was still between that of a quasi-knight and a first-level knight. It was not a big problem for him to deal with most slave creatures.

Although Hathaway felt a little uncomfortable, she was not a melee fighter, but considering the uncontrollable nature of large-scale war scenes, she did not dare to hold back. However, in order to reduce the chance of being exposed, she still released some elemental witchcraft below the quasi-level.

She was not good at these elemental witchcrafts, but no matter how bad she was, it was not difficult for a second-level wizard to cast these witchcrafts below the quasi-level.

With the addition of the demon army, the war gradually became more intense, and the casualties of the human kingdoms, elves and dwarves began to increase. Of course, the casualties of the slave army and the demon army were also not small.

Colin casually hacked and killed the invading slave creatures and demons. He was waiting for an opportunity. He needed to contact the wizard on the opposite side and send the information on his side over.

Hathaway also understood what Colin was waiting for. She did not concentrate on dealing with the slave creatures and demons crossing the river, but was silently calculating something in her heart.

"Let's go, let's move slowly down." Colin remembered Hathaway's silent message in his heart.

"Huh? Oh." Colin suddenly realized that Hathaway was reminding him.

After a while, Colin and Hathaway gradually began to move sideways downward without making any sound.

The section that the Cambrian City Guards were in charge of was originally on the downstream edge of the river. After Colin and Hathaway consciously moved downwards, they gradually reached the very edge of the front line.

"What? You suddenly remembered to ask me to come here? Do you want to get away from them and take the opportunity to escape?" Seeing that the city guards were some distance away, Colin whispered to Hathaway.

"No, I calculated that there is an opportunity here, which should be beneficial to us. Now just be patient and wait." Hathaway couldn't say much before the opportunity appeared.

Colin didn't care when Hathaway didn't say it clearly. Since they had already arrived here, they could leave at any time. The third-level magician was still in the middle of the river, far away from them. Colin was not afraid of ordinary second-level professionals.

As the war intensified, the battle line on the riverside was finally unable to be held back. In addition to the slave creature army and the demon army, the regular army of the wizarding world finally showed up. The approaching knight army and the familiar witchcraft hit the riverside.

The natives of the Esilia plane suffered greater casualties, and the opportunity Colin and Hathaway had been waiting for appeared.

A large number of fast-galloping Centaurs appeared in Colin's sight. Leading them was Knight William, holding a spear and wantonly harvesting the lives of the natives of the plane.

Suddenly he also discovered his uncle Colin, and his actions paused, but his good psychological quality allowed him to recover immediately.

After arranging Knight Locke to continue leading the Centaurs to charge, William left the team and fought with Colin.

Being close, it was convenient to do anything. While fighting with William, Colin briefly recounted what had happened since he entered the Kingdom of Dia, and asked William to tell the commander here when he returned.

But William said that the battle had already reached this side, and Colin could just leave the battlefield at any time, so why should he stay there? He also asked Hathaway to persuade Colin.

But Colin said he had his ideas, as long as normal contact was made.

After a period of fake fighting, they finally managed to hold out until the end of today's battle.

The natives of the Acillia plane finally withstood the first day's attack. Under the effect of the forbidden spell of Tanas, the third-level great magician and commander of the Dia Kingdom, Polit did not want to suffer heavy casualties on the first day, so he retreated to the riverside.

Tynk, the commander of the Cambrian City Guard, had been observing Colin and Hathaway all day today. Except for a few fierce battles when he had no time to observe them, he basically recognized Colin's "achievements". After all, Colin actually killed two or three slave creatures.

This record is not false. Although he and his wife were suspected of cheating (when they slipped to the edge of the front line), they did not do anything else out of the ordinary. Overall, they did not seem like foreign invaders.

"Let's observe for a few more days. If there is nothing unusual, we will lift the surveillance. The soldiers should be rewarded for their meritorious service. We can't let our brothers down." This was what Taink thought after the war.

Colin could feel the vague gazes on the battlefield all day long, and he probably guessed that it was from Tynk's surveillance, but he believed that he should not have revealed too many flaws. Even during the short battle with Knight William, there were other soldiers around.

It was just that Knight William and Colin both chose to let go, which made that short period of battle seem a bit stalemate. In a very short period of time, there were rarely any casualties in that area.

After getting in touch with William, Colin believed that the headquarters would naturally issue new tasks in the future. He just needed to patiently do his lurking work. If he really listened to William and directly left the battlefield, then the lurking for a year would be basically meaningless and he would not have achieved any practical results.

……

"Wizard Edith, my uncle Wizard Colin and Ms. Hathaway appeared on the other side. Let us report the situation to Commander Pollitt." After the battle, Knight William was busy informing Edith that Colin was safe.

Edith was very happy to hear the news. She finally calmed down after being upset for a long time. She looked at Sophia and said, "Thank you for your hard work, Chief Sophia."

After Colin left, although senior sister Falsa and Helen's uncle Joseph were elders, they did not want to interfere in the control of Colin's legion, so the control was handed over to Edith. However, Edith was not a second-level wizard, so Sophia was more useful against the headquarters.

"I'm happy to help." Sophia did not refuse. She and Colin had been getting along quite "pleasantly" in recent years. Although a powerful neighbor might bring some other risks, it might also bring great benefits. Sophia did not want anything to happen to Colin.
