The Witcher: Son of the Planes.

According to the time node, the main buildings outside the wizard base have been built, but the wizard tower inside is still waiting for the final debugging. Although it can be opened and used now, in order to avoid causing instability, neither Colin nor the Della family are willing to take the risk.

It will take another three days to debug. This is the result reported by the wizard in charge of debugging to Colin and the Della family.

Before Margaret left, her daughter Charlotte kept asking her to take good care of Colin and protect him as soon as possible if he was in danger. No matter how impatient Margaret was, she had no choice but to agree to her daughter's request.

But after arriving here, he saw that Colin and his men's attack was like a rainbow piercing the sun, rising step by step, with no sign of decline, so he had no intention of taking action.

The annoying Aska next to her kept chattering about how the Voltalin in their dimension were and how they were similar to the undead creatures here. Margaret felt the hair on her body grow thicker as she listened to him.

As for the other third-level strongman who was invited, he was much more reserved. Although he was facing two aliens, the gap between demigod and third level was still quite large. He did not want to make random remarks and cause displeasure to the two, so his presence seemed to be very low all along.

(Well, so low that the name Wendy Nan rarely appears.)

In this battle, the division of labor between Colin and the Della family was also very clear. The old patriarch Yurix was responsible for the construction and use of the wizard tower, and Old Tang followed Colin to command all combat troops.

Neither Old Tang nor Colin left the battlefield. Their idea was to hold on for three days. After three days, facing the powerful wizard tower, they believed that the other side would retreat. As for the space fortress in the sky you mentioned?

Well, it was rented, and all the consumption was calculated directly with the Dela family. The main gun would not be fired easily unless it was absolutely necessary. The elders of the Dela family who stayed behind were very meticulous and their calculations were more sophisticated than those of Chief Julius.

Although Colin's share of future profits will only be 30%, he does not need to be responsible for these trivial matters, which saves a lot of trouble.

When recruiting Abaddon, Colin felt that the Dark Knights and Terror Knights were similar to orthodox knights, only more rational and less humane.

But when a small group of first-level dark knights appeared in the integrated army of the natives of the Skeleton Plane and launched a charge under the leadership of a second-level terror knight, he realized for the first time the importance of the profession of knight.

In the many plane wars he had participated in before, he had never had the luxury to use knights like this. Maybe he was so generous in the early days of the plane wars in the wizarding world (in fact, he was forced to do so because there were really no slave creatures available). Later, with the increase in the number of conquered planes, a large number of slave creature armies became available, and such scenes have gradually disappeared.

The slave creature army is indeed useful. They don't care about casualties and don't feel bad about losses. But in terms of the intensity of the attack and the shock it brings to people, the knights' cluster charge undoubtedly gave Colin a new visual experience.

"Go ahead, Centaur Legion." Colin issued a new order. The Della family and Colin brought a lot of slave creatures this time, but in terms of clustering ability, only the Centaur slave legion on Colin's side had a chance to fight against them.

The dark knight cluster on the opposite side was like a cone, piercing into the middle of the Centaur slave army and continuously advancing backwards.

Just when they thought they could break through these alien races and turn around to try again, the leader of the Centaur Slave Corps, Marigao, also roared unwillingly, "Centaurs."

"We will win! We will win!" What responded to him was the Centaurs' roar in unison.

The power of the Centaurs is not weak at all, and group attacks are their strong point. However, Colin did not buy any special ones this time. He still used the leftovers from the last attack on the Esilia plane, which only had tens of thousands of Centaurs.

Moreover, there are not many professionals above level one here, which makes them seem inferior to the opponents. However, faced with the huge difference in numbers, they were able to hold them off in the end. Although they may not be able to defeat the opponents in one go, as long as they are entangled, Colin can deploy new combat methods.

Other wizards also saw the intention of this small group of dark knights, and Abaddon and others who were supposed to take the lead were transferred elsewhere at the beginning to fight against a large number of skeleton warriors.

Seeing the chaos caused by the enemy's group attack, Colin immediately pulled Abaddon and the others back, and arranged a large number of wizard apprentices to focus their fire on the Dark Knight natives.

Although they are all Dark Knights above level one, the principle of "many ants can kill an elephant" still applies to them. Except for the considerable results they achieved in the beginning, they have lost their rapid mobility.

Not only that, they are even unable to cluster.

Because the Centaurs forcibly separated them, they also began to "enjoy" the group attack from Colin's side. The witchcraft attacks of dozens of wizard apprentices were not something a first-level dark knight could easily withstand.

And it wasn't just one, but one after another. In a short period of time, more than thirty of the nearly one hundred Dark Knights fell.

Upon seeing this, the leading Terror Knight hurriedly called on his subordinates to gather around him and follow him in the evacuation.

But there is a saying that is very good and very appropriate, "When you come, you are fine, but when you leave, you can't go back."

This is the consequence of this small group of dark knights blindly charging into the enemy camp.

Although they fought desperately, in the end less than ten of them escaped, including three Level 2 Terror Knights.

Seeing that the internal destabilizing factors had finally been eliminated, Colin felt that he still had a long way to go as the general command of the front line. How could he march and fight without keeping reserve troops? Wouldn't he be in a mess when encountering such an unexpected situation?

Fortunately, the enemy did not have many people. If there were thousands or tens of thousands of these high-level professionals charging in groups, Colin felt that they might not be able to hold on. Not to mention three days, it would be considered extraordinary for Colin and his team to be able to hold on for one day.

……

"What a pity. The four-legged creatures on the other side are pretty good, but they lack high-level combat power. If a large number of level one or above professionals form a team and charge, the effect should be no less than that of the Dark Knight just now." The three giants of the Skeleton Plane hidden in the back observed and analyzed the combat power of Colin and his team.

"Well, yes, the kid in the middle, whose strength hasn't even reached the peak of level two, actually has the style of a commander, very much like me back then." said the terrifying demon lord Arthas.

"Tsk, you? You are not much different from that escaped Terror Knight." Bone Dragon King Gregory said disdainfully.

"Do you want to fight? Do you want me to loosen your bones?" asked Arthas.

"You two, can you please be quiet for a moment? Don't you want to wait and see when your promotion to level four ends?" said the Lich King, Ner'zhul.

"Hmph!" Finally, Gregory and Arthas did not forget their original intention and still gave face to Ner'zhul.
