The Witcher: Son of the Planes.

Colin was in a very good mood when he saw his mother-in-law Margaret return safely.

After all, bringing his mother-in-law to participate in the plane war this time was actually a semi-deceptive nature, and with the help of his mother-in-law's charm, he deceived His Majesty Askha, so if Margaret was really injured because of this, Colin would definitely feel guilty.

After a short rest, Margaret and her friends held a brief meeting with Colin and the Della family. The topic was the proposal of the three giants of the Skeleton Plane.

The three giants promised that as long as Colin could provide some information or knowledge points for promotion to level four, they would recognize Colin's and his team's right to rule the current occupied area and allow them to recruit other small lords on their own.

The conditions can be said to be quite favorable. If Colin and the others agree to this, the war against the Skeleton Plane can be said to be over, and it will not affect the subsequent harvest of benefits. As for the will of the plane, if the benefits provided are great enough, it may not be impossible to join the big family of the wizarding world.

But Margaret and the others just said they would come back and think about it, and did not express any agreement or disagreement on the spot.

Because whether it is Margaret, Asuka or Wendnan, they all have no perfect plan to advance to level four. Asuka is better, after all, he was promoted to demigod much earlier than Margaret, and he can be said to have touched the edge of the law. But even if everything goes smoothly in the future, it may take two or three hundred years to advance.

As for Wendy Nan, she is even further away. She hasn't even reached the level of demigod yet. It's too ambitious and not appropriate, right?

Colin has Hathaway's relationship with him, so he has no problem contacting Merlin, but will Merlin share some information about Level 4 for such a small benefit?

Colin thought about it and didn't think he had that much nerve. Hathaway could be considered Merlin's disciple, but when it came to the relationship between the wizarding world and the other world, as well as the improvement in the strength of the natives of the other world, Merlin had a lot to consider.

Another option Colin could consider was to find Master Griman, but Colin might not be able to meet him if he went directly to ask for a meeting. He first needed to find Dean Rodbell. With the little interest they had now, the other party would not care at all. Maybe he would choose to send troops directly to take over the Skeleton Plane.

The Della family can also contact the god-level strongmen through several connections, but after calculation, it is not cost-effective and the cost is too high. Instead of spending so much effort, it is better not to attack the Skeleton Plane.

How to do?

Colin and his team's proposal for the Big Three seemed to have reached an impasse.

If they hold on, with the help of the wizard base and wizard tower, it will not be difficult for the lower-level combat forces and they can hold on for a long time.

There is always a but. Margaret and the others can't stay here forever to help them guard the base.

Moreover, the space fortress is rented. Without the support of these foundations, the wizard base and wizard tower here cannot withstand the attack of the three giants.

Of course, Colin and the others could also use the excuse of needing to contact powerful beings from the wizarding plane to delay time, but this has a limit after all. You can use a few years or even a dozen years to perfunctorily deal with the three giants, but you can't go on for decades or even hundreds of years without any results.

Even if the opponent has a longer lifespan, I believe he does not have that much patience to wait. Then there is only one result, the opponent will continue to launch endless attacks until Colin and the others are killed or repelled.

The battle has been going on till now and they can only hold on with the help of Margaret and the others. If they leave, even the level 3 warriors on the opposite side will be able to find time to launch a sneak attack on Colin and the others.

If they had not attracted the attention of the Big Three, Colin and his team could have continued to develop slowly and still ensured their existing interests. But now the strength of both sides was clear at a glance, and they knew what the other side was worried about.

Then, there is only one way left, which is to convince Hathaway and influence Master Merlin through Hathaway.

If it succeeds, Colin's profit ratio will increase by ten to fifteen points as a result of Colin's efforts.

As for what else Master Merlin agreed to and fought for with the Big Three, that had nothing to do with Colin and the Della family.

After the basic discussion results came out, it was Colin's turn to do some ideological work on Hathaway.

Fortunately, Hathaway also participated in this plane war with Colin beforehand. The only problem was that Colin didn't know how important Hathaway was in Merlin's heart.

……

"Have you finished the discussion? What's next?" Hathaway asked casually with concern when she saw Colin returning to his residence.

"Well, the discussion is over. The next task is left to you and me."

"You and me? I don't think the two of us are good enough in front of so many demigods." Hathaway said doubtfully.

"Well, I just hope to ask your teacher for help and share some experience or knowledge about how to advance to level 4. The other party promised us to occupy the existing territory."

"...You're welcome. The teacher doesn't even know that I'm participating in the Plane War this time. Besides, since it involves alien races, the teacher may not agree."

"We have to give it a try. If we can negotiate, the wizarding world will have a new dimension, which will be beneficial to the growth of the world. Moreover, if Master Merlin is willing, we can gain even greater benefits."

"Let me think..." Hathaway was silently calculating something in her mind and didn't speak for a long time.

Colin could only wait quietly without making any noise to disturb Hathaway.

After about a few dozen minutes, Hathaway began to sweat. When Colin was about to wipe it for her, Hathaway finally spoke, "After my calculations, I feel that the inclusion of the Skeleton Plane into the Wizarding World system seems to be a foregone conclusion, but the details still need to be discussed. If I go to the teacher, he will most likely agree."

"Really?"

"Well, I believe in my calculations, but I don't know what the teacher will come up with. At most, it will be about joining the Wizarding World System Covenant, what it takes to reach the Skeleton Plane, and so on. In short, it can't be separated from these contents."

"Then let's go to the Bone Plane without further ado, and then go back through the plane channel."

"You should at least tell Master Margaret and the others. There's no need to rush."

"Yes, yes, let's go together." After saying that, Colin prepared to take Hathaway to find Margaret.

"It's better to go there during the day. After all, you are Charlotte's husband. If I go there, Master Margaret will be somewhat embarrassed. And you'd better invite everyone else to come with you so that it can be regarded as a formal farewell."

"Ha, you are thoughtful. Since it is getting late, Ms. Hathaway, are you willing to do something meaningful with me?" Having solved a difficult problem, Colin was in a good mood and became interested.

"Well..." Hathaway was speechless.
