The Witcher: Son of the Planes.

Colin's contact with the Emerald Island was very smooth. Whether from Colin's current strength or kinship, there was no reason to refuse, not to mention that Marcus was also an official first-level wizard.

Now that the communication was complete, Marcus was ready to go to the Emerald Academy to show his talents, so he naturally didn't want to stay in the city of Morgwen any longer. After saying goodbye to Colin, Helen and Connie, he hurriedly boarded the airship to the Emerald Island.

Ever since Rose left, Helen felt that she could no longer fully control family affairs. Many of the guards she had brought from Emerald Isle had grown old, some had returned to their families, and some had died of old age.

In desperation, they could only let Edith, the young master's mother, take care of it herself. The insight of a first-level wizard was naturally extraordinary, and some possible intrigues would naturally disappear without a trace.

After Marcus left, Colin had the idea of ​​going to the underground world again. His second child was about to be born, so he had to earn more money for milk powder. After reporting to his teacher Lina, Lina told him that he must return within five years, and no later than ten years, as the Heaton family might have new actions.

Of course, during the period before Colin went to the underground world, Helen and Connie increased their exploitation of Colin. As to whether there would be any results, everything is still unknown.

As for having children, Colin has always let nature take its course and never forced anything. After living there for a while, Colin could no longer bear it and, after many instructions from his family, Colin finally decided to leave.

……

The first level of the underground world was still not much different from before, and there was no sense of the war that was being waged on the third level with the demons in the underground abyss.

Colin, who was in the city of Vatna, felt a little envious when he saw the extremely hot sales in the major stores. Perhaps a hint of the gunpowder of war could be seen from the enthusiastic buying and selling of goods in the stores.

Colin tried to contact several friends, including several friends from the Tauren tribe, but none of them were there. However, their chief, Gamor Bloodhoof, wrote back, saying that the Tauren were employed by the third-floor wizard tower, and many of their tribesmen had gone down to the third floor to earn extra money.

Colin tried to contact Dara Beng again, whom he hadn't seen for many years. Unexpectedly, he succeeded this time. Dara Beng succeeded in breaking through and advancing to the second level after failing once. Although it caused considerable damage to his body and it was unlikely that he would be promoted to the second level, he was promoted to the first level, which made him an existence that could not be ignored in the underground layer.

It was a coincidence that Colin was able to contact Darabang this time, because there is both competition and cooperation in the third layer of the underground world. Facing the attack of the abyss demons, there is of course more cooperation.

As the backbone of the wizard tower on the first floor, Darabang naturally had to contribute his part. It was a coincidence that he came up this time, and once again recruited adventurers and warriors of various races on the first floor to serve on the third floor.

Colin was just about to try his luck on the third floor. Since his old acquaintance Dara Beng was also doing the same, he naturally signed up with him. If he made a contribution, a small portion of the merit points he generated would naturally go to Dara Beng.

Unlike other warriors of various races who have lived in the underground world for a period of time and need to buy some supplementary supplies and medicines, Colin had already prepared all kinds of supplies before going to the underground world, so naturally he would not buy high-priced items in major stores.

Daraben still needs to recruit a group of strong men. His task is to recruit high-level combat forces. Colin also needs to understand the situation of the Abyss Demon Clan in advance. Since he has already signed up, there is no need to rush.

Three months later, it seemed that Daraben had recruited the right people. Daraben signed a contract with everyone on behalf of the wizard tower on the first floor of the underground world.

Of course, the contract will also vary according to the strength of the person who responds to the call. As a powerful first-level wizard, Colin is naturally treated very well. Colin took a look at the content of the contract, which is no less than going out to participate in a plane war.

Colin had never been to the third floor before. The last few times he came to the underground world, he only bought some things at the auction house on the second floor. This time when he arrived at the third floor, his most intuitive feeling was the strong atmosphere of war and the heavy smell of blood. The various ethnic groups walking on the road were also in a hurry and very cautious.

Under the leadership of Darabang, Colin and others followed him to a camp, which was a support camp on the first floor of a wizard tower. After bringing Colin and others to the destination, Darabang left as he needed to complete other tasks.

The person who contacted Colin and others was a first-level wizard named Gareth. He was one of the people specially sent by the three-story wizard tower to connect with the reinforcements from various places.

According to Gareth, no matter who the contract was signed with, since you have come to the third floor of the underground world, you are here to serve the third floor of the underground world and must obey the management of the third floor wizard tower.

Colin took this to heart. After all, you are here to participate in the war, and it is definitely not okay to be unmanaged. Although he signed a contract with the first-floor wizard tower, without thinking too much, Colin also knew that there must be a relevant agreement between the first-floor wizard tower and the third-floor wizard tower.

Gareth continued to explain the relevant precautions. There was nothing else to say, just be obedient and follow the arrangements. There were many camps like the one where Colin and his team were, and this was just a camp for the supporters of the wizard tower on the first floor. Each camp would take turns to fight in order.

Given that Colin's camp is short of manpower, and the newly recruited Colin and others still have about half a month to familiarize themselves with the situation.

The rules were made clear, and everyone understood the responsibilities that needed to be performed, so Gareth did not stay long and went back to other things.

Colin had learned a lot from Dara Beng on the first floor, such as the races of the Abyss Demons, those who were above level one, those who were good at sneak attacks, etc. However, these were all oral narrations from Dara Beng, and Colin wanted to check it out for himself.

After asking relevant people, Colin plans to follow people from other camps to see the specific battle scenes tomorrow.

Colin's requirement is that you arrive on time when it is their turn to fight. There is no mandatory requirement to stay in the camp. After all, the contract has been signed, and they are not afraid of you deserting the battlefield. If you actively violate the contract, the punishment from the will of the wizarding world will naturally make you pay a heavy price.

After a night's rest, Colin appeared outside the camp early the next day, waiting for the battle from the neighboring camp.

Not long after, a group of warriors appeared in the camp next door, and Colin followed them to the battlefield.

While rushing to the battlefield, Colin saw troops from other camps constantly joining in, and finally tens of thousands of warriors gathered and marched towards the battlefield.
