The Witcher: Son of the Planes.

In the past few years since Colin returned to the wizarding world, he hadn't had time to deal with Raul's family and the legendary wizard Slibo before the invasion of the abyss plane occurred. It's just right, there's no need to think about anything else, you guys can come along too.

As for the communication with the Victoria's Secret Magician Council, we can only wait until the invading army from the Abyss is resolved. Do you think they won't live to see that time?

That's because they have a hard life. The Victoria's Secret Wizarding Council also missed an opportunity for communication. Colin is now an orthodox wizard, and the Wizarding Council is just a supernatural organization in the place where he was born. What's more, Oscar is a good leader now.

A demigod-level wizard who is also a third-level magician is also one of the most powerful. Although Colin still holds the status of an honorary elder, the connection between them is not as close as it was at the beginning.

It will take some time for Colin to assemble his army, but several forces close to the latest entrance to the underground world have already begun organizing advance troops to enter the underground world.

All kinds of extraordinary powers on the first and second layers of the underground world will gather on the third layer to resist the invasion of the Burning Legion with all their strength.

According to the news from my old friend Beta Bloodhoof, the entire Tauren clan, except for the underage members, even the females have begun to go to the battlefield. As a force in the underground world, they will not and cannot avoid this large-scale battle.

According to the intelligence Nora collected, the Blazing Knights of the Magik Empire have already set out, the Warlock Family of the South Coast has also sent out a coalition force, the Third Legion of the Thunder Knight Empire is also being urgently mobilized, and the improved airships of the floating city have also begun to be delivered to various major forces. The war is beginning to affect every force in the wizarding world.

The slave army is of course the main force of the first wave of charge, but the mortal world is not immune. Instead, it is necessary to build a large-scale defense system near each exit of the underground world to prevent the abyss demons from bypassing the front battlefield and sneaking into the surface world.

As for Colin, although he had to respond to the call of the entire alliance conference to send troops, he could not just leave Emerald Island alone. He originally hoped that Sophia could stay and look after it.

But the sea wizards also have combat missions. Although they don't get along well with Poseidon, Sophia can't openly violate the arrangements of the Alliance Conference and not send troops regardless of the consequences, especially when she is still a level four combat force.

In the end, Colin could only leave Helen and Nora behind, and let Locke and Deborah, his niece Emily, and his old friend Marcus stay behind, while all the other relatives and friends followed him into the underground world.

Hathaway returned to Emerald Island several months later. When she brought back the news, Master Merlin and his men had already relocated and modified the plane coordinates. However, he could not take any action before completely cutting off the connection with the Abyss World, and neither could the three guardians. Therefore, the first wave of battles could only rely on the joint efforts of all major forces.

From this point of view, the Burning Legion that came from the Abyss Plane is not much different from the high-level combat power of the Wizarding World, but in terms of extraordinary power from level two to demigod level, the Burning Legion has fewer, after all, the Wizarding World is fighting on its own land.

When it comes to bottom-level combat power, the wizarding world still has the upper hand, but it takes time for the major forces to mobilize the slave legions, and the Burning Legion also needs to be completely deployed through the Gate of the Abyss, so everyone is in a hurry.

The third layer of the underground world has already engaged in battle with the first wave of the Burning Legion's troops. Faced with the massive amount of abyss demons, only large-scale wizard towers can resist for a longer time. If the natives of the underground world rely solely, they will soon be wiped out.

The joint reinforcements of Colin, Lina and Sofia were the second wave to arrive in the underground world. They were received by the wizard Phyllis who used to work at the second-floor Holy Tower Auction House. This former second-level wizard has now reached the peak of demigod level.

"It's Wizard Colin, Wizard Lina, and Wizard Sophia," Phyllis confirmed.

"It's us, you are Phyllis?" Colin continued.

"Yes, I didn't expect Wizard Colin to know me. It's an honor."

"Yes, I've been to the underground world's exchange before. At that time, Wizard Felice was the host and sold a lot of valuable items."

"It seems that Wizard Colin also knows about the underground world. This makes things easier. The third-floor Wizard Tower has been destroyed by the enemy, and reinforcements from various forces are still arriving. We are building a new defense system near the second-floor Matasia City. Wizard Colin, you can divert some people to stay here to help build the Wizard Tower."

Phyllis is such a wonderful person. As soon as Colin heard it, he knew that the other party was doing him a favor. Now everyone is busy heading to the third floor of the underground world. The third floor has not been lost. Although the second floor does have the requirement to build a defense system, you, an external reinforcement force, actually want to stay and do this kind of logistical task. You are really overthinking.

Colin guessed that the other party should have some understanding of him, and seeing that the three level four strong men came together this time, they just wanted to make friends with him in advance.

But having said that, it is also necessary to leave some people here. If the third floor cannot be defended, the defensive position on the second floor will be very important. Therefore, it is even more important to plan ahead and have a suitable piece of land. Otherwise, after retreating in the future, there will be no place to stand and you will have to squeeze with others.

Colin, Sofia and Lina are all family members, so it only takes a few words to decide who will stay behind. Helen's nephew, the third-level knight William, and the third-level wizard Edith will stay behind to lead some wizards from the Emerald Academy and a small number of slaves to complete the task of building the wizard tower arranged by Phyllis. The rest of the people will continue to follow Colin and the others into the third layer of the underground world.

Phyllis did not leave the second floor. He simply arranged a guide and then went to receive other support troops.

It doesn't really matter whether there is a guide or not. First, Colin knows very well where the battlefield between the demons and wizards in the third layer of the abyss in the underground world is. Second, small forces can be seen coming and going everywhere on the road, but Phyllis also has good intentions.

Colin and his friends were led by their guide Tuan. According to Tuan, he was one of Phyllis' registered disciples. He used to be Phyllis' subordinate, but was later accepted as a disciple. It was considered a quick achievement.

But he didn't catch the right time. Not long after he was promoted to the second-level wizard, he encountered this big action in the underground world. It is hard to say whether he can survive to the end.

Colin was not as pessimistic as Tuan. He felt that the wizarding world would definitely defeat the Burning Legion completely, but he just didn't know how many people would die.
