The Witcher: Son of the Planes.

The envoys of the three major human empires all rushed back, busy reporting the latest agreement contents to their home countries and carrying out the most extensive mobilization.

The Elf Kingdom has completed mobilization, and this time the ancient war tree has also joined the war.

Needless to say, Listan's slave armies are all stored in another dimension, and they can join the battle at any time as long as they are brought to the battlefield. As for those wizards and knights, they have long been accustomed to war, and even those who are participating in the war for the first time are not unfamiliar with it, and are waiting for the order for the general attack at any time.

As the orc coalition forces retreated a hundred miles ahead of time, there is currently no fighting between the two sides. However, after the orc emperor Bolt Tiger issued an order for a full resistance, soldiers from all over the country have begun to rush to the vast plains.

Steelmane City, where Barrick is located, is seriously short of mid- and senior-level generals because of a trick played by Colin before the war. But this time it is an all-out resistance. After arriving at the vast plains, they will be regrouped. Not only will all the new barracks be sent out, but some male orcs and some female orcs of powerful races will also be forcibly recruited in the city.

……

On this day, whether it was a coincidence or fate, when the orc army arrived at the vast plains, the armies of the human countries, the elven kingdom, and Listan also arrived at the designated battlefield. This time, it was the elven coalition that took the initiative to advance nearly a hundred miles.

The largest war in the Agri plane in nearly a hundred years is about to break out!

The troops Colin was in were still under the leadership of his old superior, the Knight Beruk. This war was something Colin had never experienced before. Compared with the previous times, it was far more numerous in terms of personnel size, high-level combat power, and number of races.

Although the vast plains are very broad and the battle line is very long, what Colin wants to say is that it is not long enough, because the troops of both sides cannot be fully deployed, and the battle line of hundreds of kilometers is simply divided into nearly a hundred combat zones.

人类三大帝国各自负责15个战区，精灵王国负责10个战区（第1到10），利斯坦独自负责45个战区（第11到55），而科林所在的位置就是被临时定义为第55战区的作战区域，这里紧邻奥斯帝国负责的第56战区。

Although generally speaking, Listan is a guest army and a reinforcement, but considering that Listan occupies 45 war zones, it seems not wrong to call Listan the main force.

The 55th War Zone was assigned 8 slave creatures, 500 knight squires, 30 knights, 100 wizard apprentices, and 20 wizards. The Dwarf Musketeers were hired by the Oss Empire, so this time they returned to their employer and were assigned to the 56th War Zone.

The orcs facing Colin and his men might not be divided into as many areas as theirs, but it seemed that there were more of them.

It is not an exaggeration to describe the two sides as enemies meeting and being extremely jealous of each other. The atmosphere is right, and there is no need to issue any special orders for a general attack. Just one word, "Go!"

Colin did not stay behind. There was no need for any fancy stuff on such a large battlefield. Just use whatever has the greatest lethality and the widest coverage. With the joint cast of several wizards, the large-scale group attack spell, Fire Thunder Star Shower, was formed and smashed towards the opposite side.

The orcs' bodies had already glowed red, and it was obvious that they had gone berserk on their own. In addition to the red light, there was also a circular halo.

It is obvious that the opponent's configuration has also improved this time, and their shamans have taken action. This aura should be an endurance aura, which can quickly restore the orcs' physical strength and injuries.

But no matter what kind of halo it is, a fire thunder star shower with such a wide coverage cannot be resisted by simply adding a halo.

Within the range, orcs below the low level were vaporized directly, some low level orcs were burned to death, and some were still struggling while dying. Those above the middle level were slightly better off, not to mention those who were unlucky enough to be in the center of the range, but all the clever ones avoided this spell attack.

In the following time, Colin and his companions did not release any joint spells, but each of them showed their unique skills. Some released chain lightning, and some released ice storms. Colin was still the same, releasing the group attack spell Rain of Fire, and each time he could take away nearly a hundred orcs.

The slave creatures at the front have already fought with the orcs. Both sides are shed their blood in a small space. If you cut me, I will definitely bite you. Even if you fall down, you don’t want to have an easy life. My comrades can definitely take you away. The main word is "consume!"

Colin did not pay attention to other war zones. Just on the few kilometers of the 55th war zone, the total number of troops deployed by both sides was close to 20. In addition to the large number of orcs who fell, many slave creatures also died, especially the attacks of some "beasts", which sometimes made them unable to defend themselves. However, compared to being enslaved for a long time, perhaps death is more of a relief.

The battle line between the two sides is undoubtedly the most brutal. This linear millstone of life and death constantly reaps the flesh and blood of both sides. Occasionally the line will be twisted, but it will soon be straightened and return to its original state.

The light of the stars gradually faded away, and the fierce fighting between the two sides was getting more and more intense, with no sign of stopping. Colin's mana reserves were top-notch among those of the same level, but the frequency of his spellcasting was much lower. This was still good, at least Colin had not taken any replenishing medicines, while some of his companions had already taken mana potions for the second time.

Lord Beruk had not been watching the battle from the rear for a long time. He joined the battlefield at dusk. Rushing out with him were the last reserve forces of the 55th War Zone. The 55th War Zone had put all its strength into the battle without holding back at all.

Strictly speaking, the number of casualties on the opposing orcs is much greater than that on Colin's side, but the overall number of orcs is still large. Up to now, the opponent is still continuously attacking the weak battle line.

Colin was ready to take the mana potion. His mana had already run out. In order to prevent any unexpected situations, he must not wait until he was completely out of mana before taking the potion. He took out a bottle of mana potion and poured it into his mouth. The mana potion flowed into the stomach through the esophagus. The effect was very obvious. Soon Colin felt that his mana was recovering at several times the speed. In a very short time, his mana reached 60%.

Suddenly, Colin felt a surge of malice like a tide. It turned out that an harpy on the battlefield was rushing towards him.

The harpy is somewhat similar to the harpy encountered before, but also completely different. The harpy is a monster, while the harpy is an orc.

Except for the incompletely evolved limbs and beak, the harpy's other physical features are almost the same as those of humans, except for the pair of wings that are five meters long when spread out.

Colin looked at the approaching harpy, wondering why the other party chose him, but he was not afraid. He would use his strength to tell the other party, "If you want to die, you should do it as soon as possible. If you find the right person, you will be wiped out in a minute."
