The Witcher: Son of the Planes.

After Colin and his team arrived at the wizard base on the second floor, they saw that it was in a mess. They did not expect the other side to launch a general attack so quickly, and the wizard base on the third floor fell after a short while.

The time left for the second floor is too short. Although everyone is trying their best to contribute their efforts, it will take at least a month to build it to the scale of a third-floor wizard base.

But there is not enough time now. The frontline troops of the Burning Legion have already occupied the main passages between the second and third floors. It will take only half a month at most for the main force to arrive here.

Of course, this does not mean that there are no other passages to travel between the second and third floors, but compared with this passage that can pass large troops, it seems less important.

Master Merlin and his men will be involved for a while, about three months, so the second and first floors need to resist the Burning Legion for at least three months.

Fortunately, all major forces received information about the tragic situation on the third-floor wizard base at the same time, so they all accelerated the speed of their support. While the wizard base was being built on the second floor, construction on the first floor also started simultaneously.

But compared to the second floor, the first floor has a more disadvantageous factor that is, there are too many passages. There are also several passages that can pass large troops. If the defense is dispersed, it will undoubtedly increase the pressure of defense. Therefore, some wizards proposed to blow up several passages in advance and reopen them later.

The idea seems to be a good idea, but it is actually a bad idea. Not to mention the abyss demons who have lived in the underground world for hundreds of years, they are also very familiar with the location of the passage leading to the surface world from the underground world. You can't avoid it by just blowing it up.

The Burning Legion has a large number of troops. Won’t they split up their forces to dig?

But even with such an idea, there are actually a few wizard leaders from major forces who want to try it out. After all, it is much easier to concentrate all their efforts to defend one place than to defend several places.

According to conspiracy theories, even if it reaches the surface, it may not cause any substantial harm to those large forces. Isn't there Master Merlin?

Only a few big forces near the passage are worried. They were the ones who benefited the most in the beginning. Now in this situation, the pressure is also on them. They are more worried than others.

The Grimaldi Islands is one of them. When Colin was studying at the Grimaldi Wizarding Academy, he made a lot of money by traveling between the surface world and the underground world. Now with this passage, the Grimaldi Islands are also worried.

But the others are old and powerful forces, much stronger than Colin. Although the one in power now is Dean Rodbell, Grimman has not fallen. During the two hundred years that Colin has been in the plane of the gods, they have almost recovered. Although they lag behind some other big forces and have not been promoted to level five, their strength is not weak at all.

Moreover, the Griman Islands has another characteristic: it is a large island. It would be tragic if the Burning Legion were to break through from here in the future.

Except for those middle and high-level demons, it is difficult for those low-level demons to leave the Griman Islands and reach the main continent of the wizarding world.

If you are confined to such an island, no matter how you think, it will be useless. So in terms of the degree of danger, it is actually less dangerous than the passage near the Megwen area where Lina's family is located.

It is still a bit far-fetched to say this. Colin and his companions do not want the Burning Legion to break through to the first level. They hope to resist the enemy on the second level.

The decision to blow up the passage was not ultimately carried out, as more wizards had a sense of the overall situation and knew that this sneaky approach would not solve the problem at all.

……

"Old friend, the third floor has been lost. How long will it take you?" asked Arthur, a level five knight.

"I already know about the loss of the third floor. In my prediction, the second floor will not be able to be defended either. The enemy is attacking very quickly this time, and there is a high chance that they will rush to the surface. I really don't have much time left.

But I also figured out one thing. This time it's not the Abyss's full-scale attack on us. It's just Magros himself leading the Burning Legion alone. If I were to deal with him alone, it would be easy. With the bonus of the plane's will, I can completely hold him back.

With the help of the three guardians, it is not impossible to kill him.

As for the remaining demons above level 4, they are not superior in numbers at all, you can easily defeat them. In addition, after they attack the surface world, you need to send an elite team to the base camp of the Abyss Demon Clan deep in the underground world, completely destroy the Abyss Gate, and cut off the connection with the Abyss plane, so as to completely eliminate the hidden danger this time."

"I'll go then," said Arthur.

Merlin looked at his old friend Arthur, the partner and relative who had accompanied him all the way. He gave up the opportunity to build his own power on his own, and often chose to be self-reliant, paying too much.

"It's quite dangerous. You can't go alone. You should take some other people with you. Oh, and take Colin with you. Taking him with you may bring you unexpected luck."

"What about Colin? I haven't seen him for a few years. I will make arrangements. Don't worry. I believe that after we get through this crisis, the wizarding world will become more prosperous."

"I also firmly believe that we can survive this disaster. There is nothing to fear from Magros."

……

Colin didn't even know that he was forced to take on a new task, which was arranged by Hathaway's teacher. Now most of his attention was focused on the construction of the second-floor base.

There are many level four experts here. In terms of strength, he may not be the worst, but in terms of promotion time, he is indeed the last, so he does not have much say.

Although Lina and Sofia came with him as part of the coalition, the command center on the second floor was more willing to acknowledge Lina's status. After all, Lina was stronger than Colin and had been promoted much earlier.

According to the division of tasks here, Colin and his team need to be responsible for the defense areas of the three wizard towers. Fortunately, they have four level four warriors, so the pressure is not great, but the construction speed cannot be increased. It is estimated that by the time the Burning Legion attacks in large numbers, it will be good if they can build two towers.

Both sides were racing against time. Half a month passed in a flash, and the Burning Legion's large force finally passed through the passages between the second and third floors and marched quickly towards the wizard base on the second floor.
