The Witcher: Son of the Planes.

Arthur and Colin met at the back of the second-floor wizard base. When Arthur came, he only brought a fourth-level knight and a fourth-level wizard, which did not alarm too many people. Only a few people at the second-floor wizard base knew that Knight Arthur had been there.

"Uncle Arthur, is there something important this time? Are we going to launch a general attack?" Hathaway took the initiative to accompany Colin, just to find out what exactly was going to be done.

Arthur looked at Hathaway lovingly. Although Hathaway was Merlin's disciple, Arthur felt that she was no different from his own disciple. It was just that Hathaway did not have the talent of a knight, so she could only learn predictive witchcraft from her old friend.

"Well, there is a mission that is very important for us to completely defeat the Burning Legion. Your teacher Merlin saw Colin's luck and hoped that he could go with me."

"Wizard Colin, on behalf of the Wizarding Union, I solemnly ask you whether you are willing to complete this sacred mission for the wizarding world."

Colin was drunk and didn't even know what task he was supposed to complete, but he was put under such a big label and said he didn't want to. Is it appropriate?

Not to mention Hathaway's relationship, how could I refuse Master Merlin's arrangement?

"I do." That was the only answer Colin could give.

Arthur nodded. It seemed that the little guy still had some sense of the overall situation.

Hathaway was anxious, and hurriedly pulled Arthur's arm and shook it, saying, "What kind of mission is this, Uncle Arthur? You're driving me crazy."

Arthur looked at Hathaway. There was no one else around, so there was no possibility of the news leaking out.

"I need to take Colin to the third level of the underground world, the base camp of the Abyss Demon Clan, to destroy the Gate of the Abyss."

"Ah? The Gate of the Abyss? Shouldn't we launch the general counterattack and then naturally reach that location and destroy it?" Hathaway asked in surprise.

"If that were the case, it would cause more lasting damage to the wizarding world. The Burning Legion must make quick decisions and rush to the surface world as soon as possible. We also want to make quick decisions and get rid of the opponent as soon as possible. This is also the idea of ​​your teacher Merlin." Arthur explained.

"Colin, what do you say? If there is no special situation, we will leave overnight." After Arthur answered Hathaway's question, he was ready to take Colin to complete the task.

"Lord Arthur, I'll just tell Hathaway a few words and then I can leave."

"Uncle Arthur..." Hathaway was still saying something when she was taken out by Colin.

"I have no other requests, except that you, Sister Lina, and Princess Sofia must work together to survive until victory. At the same time, you must try your best to take good care of our people. If the war goes wrong, you should leave. Master Merlin will naturally have other arrangements. Don't fight to the death."

"I understand, and so do you. The teacher is a level six wizard, so there must be a way. If you really can't accomplish it, just withdraw first." Sometimes it is difficult to distinguish right from wrong in front of family members, and the overall interests are sometimes not as important as family members.

After the two looked at each other affectionately for a few seconds, Colin took the lead and followed Arthur away.

Hathaway came out with Colin and went back alone to explain everything to Lina and the sisters. Her husband Colin had gone to complete another mission.

……

After Arthur took Colin and the other two out of the wizard base, they quickly went around the back to another fault. Although there were many small groups of demons below, none of the four had any intention of destroying them.

There are many roads from the second floor to the third floor. Under Arthur's leadership, the few of them quickly found the nearest cave and passed through it.

Several of them were strong warriors above level four. Not only were they fast, but they also made little noise. Even after passing through several demon armies, they did not arouse the other side's vigilance and easily reached the third level of the underground world.

After reaching the third floor, I found that this place had become a paradise for demons. The original ruling system had completely collapsed, and the natives of the underground world had now become lambs for the demons, to be slaughtered at their will.

Even Colin, who was a "hard-hearted man", felt a little reluctant at this moment, but he couldn't care less about them because he had more important tasks.

"Everything will pass. The shorter the time we take to complete the mission, the greater their chances of survival. Let's go," Arthur reminded the three.

When Colin and his companions arrived at the ruins of the original three-story wizard base, they found that there was still a small demon squad stationed there. Colin briefly paid tribute to the wizards who had fought to the death here, and then followed Arthur to continue moving deeper.

These will be restored and rebuilt after the war. Colin alone can easily eliminate the small team below, but now is obviously not a good time to eliminate them.

"Don't worry, these demons will be made to pay with blood." Arthur also noticed Colin's discomfort.

Continuing to go deeper, they soon crossed canyons and gullies and headed towards the base camp of the abyss demons.

As the distance got closer, the number of demons here continued to decrease. Perhaps Magros did not expect that the wizards would send some people to attack their base camp.

The journey from the second floor to their current location was smooth. They did not provoke any demons along the way, nor were they discovered by the demons. As long as they reach the base camp of the Abyss Demon Clan, the mission will be half completed.

……

Although Colin and his team were very fast, the fighting here became fierce again after they left the second-floor wizard base. Some wizard towers that were not built in the early stage had no chance to be completed.

The few wizard towers that were built began to suffer damage under the enemy's desperate attacks.

Lina and her team were pretty lucky. They took advantage of this period of time to erect the half-finished wizard tower. With the two wizard towers cooperating with each other and Lina's maneuvers outside, the situation here was relatively better.

The three female generals arranged Edith and others in the wizard tower, and their close people were also arranged in convenient retreat positions.

Although William, Conrad and others wanted to charge in, talking about the glory of knights and so on, Lina refused to allow it. She needed to complete Colin's instructions and minimize the damage to her relatives and friends.

As for what you said about the slave army suffering heavy casualties due to the lack of high-level generals (wizards and knights)?

What about Lina?

As long as our relatives and friends are not killed or injured, isn't the slave army meant to be consumed?

Cannon fodder is cannon fodder. If they don’t die here, they will die in the defense of the wizard base on the first floor.

Well, there is nothing wrong with Lina's thinking. Conrad and his men have experienced so many plane wars, but their thinking has not changed completely. It's nothing more than the loss of some money. The damage to relatives and friends is what Colin is unwilling to face.
