According to rumors, the Great Wizard of Ubus had already entered the threshold of an eighth-order wizard six or seven years ago, and he was only stronger than Chen Xuyuan.

I thought it was a diplomatic document or some kind of alliance contract under the city, but Master Chen, who had already taken the parchment scroll casually, paused his right hand slightly, and exchanged a few vague messages with Master Bruno's eyes, and then unfolded it to see that it was indeed the cultivation and improvement of several wizard spells in different fields, they were:

Command Plants in the Plant Field. It is a fourth-order spell. Can only control 1 or more plant creatures, communicate with the caster on a friendly basis, and cannot control the opponent from committing some suicidal behavior against their will. It's definitely too much to use this spell to launch an artillery sea tactic similar to "scattering beans into soldiers", after all, this spell also needs to consume a moderate amount of mana. Therefore, it is not very useful, but whenever a spell is created, it is always worth learning and learning. In the past, Chen Xuyuan used the elimination method to tame the animals, and then stuffed the soul into some living things, dead corpses, and objects, and then tried to use spells to communicate command and control. This kind of spell that directly commands plants would be a good addition to simplifying his refining of functional magic weapons;

This seemingly lethal spell is also Monahsini's "well-intentioned" choice. The greatest value of this spell for tribal shamans is to help them ask if herbs are poisonous and to understand their properties, or to help them find places in the mountains where certain edible fruit trees and medicinal herbs grow in abundance.

The other two spells are the Song of Madness in the Hate Realm, which forces several people who are not determined to attack each other in a frenzy. This spell seems simple, but not many people can understand and learn it. Like modern medical knowledge, it is necessary to have a certain understanding of the operating mechanism of the biological brain, which cannot be easily learned by simply dissecting a few corpses. In terms of the Karui lifestyle, it is basically difficult to obtain the high-end knowledge of the Plains that they have blocked;

The last Corruption Field's [Blight Technique] can infect the recipient with a specified disease;

The other party took out this spell, and if it was another caster, it didn't have to think too much, but it also had a name among the Karui people: it was also called Gu Poison by the shamans, a terrifying spell that was easy to learn, but could not control the consequences when released, and represented a great and subtle threat of death.

This means that the other party is in a major crisis of extinction, and is no longer afraid to use the last resort.

The Karui siege equipment and armor weapons completely lagged behind the surrounding farming nations. But why have they plundered their caravans from ancient times to the present day without being encircled and exterminated by large armies sent by the kingdoms?

Although the Karui people are fierce, and the nomadic tribes of the steppe desert are the same custom that almost all the people are soldiers, it is not easy to completely eradicate them. The peninsulas scattered in the southwestern corner of the continent, as well as the mountains and cold forests, and the islands scattered along the southwest coast are inhabited by the Kalu people, and it is difficult to concentrate and completely exterminate them. And even if the northern mountain Karui people are wiped out, every year there will be tribes further south that split into smaller tribes due to overpopulation and gradually migrate to fill the land gap.

In a head-on confrontation with the elites of various countries, the wise men of the Karui people will definitely not let the clansmen fight hard, but will run around and fight a guerrilla war in the mountains.

If the soldiers of several surrounding countries spend a lot of effort and mountain people playing hide-and-seek in the mountains, it will lead to the embarrassing situation of the US military in the quagmire of the Vietnam War, and will be slowly dragged down by huge logistics supply lines.

The logistics of the armies of various countries also have some space equipment used to carry important military supplies.

However, ordinary spell equipment such as space bags cannot pass through portals, or be carried for remote teleportation, which will cause the space spells inside to open up and anchor space fragments with spells to temporarily fail - the contents inside will be directly thrown by the space rift and all thrown to the unknown plane. Even if the space bag spell is constant again, it is impossible to randomly link to the vast and nearly infinite space fragments and find the original one.

But those are not the most important reasons.

The reason why the Karui wizards made the high-ranking people of the surrounding countries jealous.

The most important thing is just one thing.

Ancient times.

When the Karui tribal alliance was strong, it also tried to launch frequent attacks on the Azmerians, Azmeris, and Oriaths on the plains, competing with them for a wider area of survival and arable land.

However, some of the sharp-eyed shamans of the Karui tribes during the war found that although the enemies were docile farming peoples and were not kept in feudal slavery by much ferocity, their superiority in the enemy's endless war equipment and spell equipment was enough to put their own side in a slowly weakening disadvantage in terms of strategy. Some of the most ruthless shamans thought about how to turn the whole strategy around, and finally they got inspiration from what they found most difficult and terrible in their own life experience: the plague.

When they collected some lethal pathogenic bacteria such as Ebola, sleeping sickness, Hendra virus, Congo hemorrhagic fever, Maqiubo virus, Marburg virus, Lhasa fever, rinderpest, etc., from some diseased animals in the jungle, they mixed the dead corpses and cultivated them into terrifying biological and chemical weapons that made their people smell and colored, and finally put them on the battlefield of the decisive battle.

The Karui counted the beginning of the war, but did not have the last laugh at it.

The final result of that war was that there were no winners, and the battlefield was full of dead bodies that bled and died of illness, and the military flag camp tents were discarded at will in the [Death Plague Battlefield] where even vultures did not dare to visit. The armies and clansmen of both sides fled after the virus got out of control, but most of the people who returned from the battlefield were still infected with this terrible [Unknown Plague], some of the soldiers who deserted and went straight back to their hometowns, and many other people in the interior of the country.

Because of the backward medical diagnosis technology at that time, it was impossible to distinguish between a carrier of the virus and an early symptomatic person. In the end, the king at that time was relentless and sent troops to seal off the suspected infected areas, making the troops wear masks, and the surface of the armor and the wells in the streets were sprinkled with quicklime.

One morning, the king ordered all the blockades to be slaughtered, not even the slightest sign of the disease, and all the villages were burned for days and nights, and even the forest fires in the surrounding area continued for weeks, killing and wounding hundreds of thousands of people, and finally eradicating the plague.
