Kel'thugad was already very interested in psychics.Don't look at the undead knights in this world were invented by Gul'dan, in fact, necromancy has appeared in Azeroth for a long time, and even necromancy in humans can be traced back to the first batch of mages who learned magic.Merry Winterwind, who participated in the Troll War at a young age of 3,000, was the first necromancer of mankind.The old mage is still doing his best to protect Azeroth in his undead state.Unfortunately, psychics are not well received by mainstream magicians, and they are also ostracized in Dalaran, and Kel'thugad himself has a great interest in psychics, and of course many of these experiments have to be carried out secretly.This war between the Horde and the Alliance gave Kel'thugad a glimpse of the power of the undead, especially the appearance of the Death Knight, which represented the future development direction of the psychic school.That's why Kel'thugad actively participated in this war, and did not hesitate to go to the front line himself, capture two undead knights, and bring them back for study.He even proposed at the meeting in Dalaran that the Alliance should also have its own Undead Knights, but his proposal was opposed by almost everyone.Dalaran's various schools of thought hate psychics, and this kind of play with life and soul is basically difficult to support everywhere.The church forces in the alliance are even more opposed, originally the church is an organization that uses the Holy Light, and they naturally locate the undead to the evil camp, and the guys who use the Holy Light always put themselves in the position of "justice" without authorization.Moreover, there is also the problem of power struggle, after the Stormwind Kingdom revealed the training method of paladins, the forces belonging to the church began to train a large number of physically strong priests to become paladins by relying on this method, and began to look for adapters from the army.This has greatly increased the status of the churches in various countries, and at the same time, there are many military people who have risen in status and occupied high positions, of course they don't want their status to be threatened, and the undead knights are all from the dead, and the dead come out to grab the rights of the living, of course, they can't get the support of the living.In fact, this proposal should only be somewhat agreed by ordinary soldiers in front-line battles, because regardless of whether magic is evil or not, mitigating death is true, and only ordinary soldiers of Finn who are really in danger of life don't care about this, and just want to have a way to reduce their chances of dying on the battlefield.Ordinary soldiers and officers are completely different in this regard.It is a pity that ordinary soldiers did not have the opportunity to participate in the meeting.So Kel'thugad's proposal fell through.Later, a somewhat disheartened Kel'thugad received a package from an anonymous member of the public, and after making sure that there was no danger, he opened it and found the Book of Medivan.The magical knowledge in the book is all-encompassing, and the name of the book makes Kel'thugad think about it, regardless of whether there is danger in it, and eagerly absorb the knowledge in it.As he read more, Kel'thugad became more and more aware of necromancy, and he would often go to the front line of battle, because it was the only place where he could study necromancy openly on the front line, after all, no one could argue with the enemy's tactics.In the course of continuous combat and research, Kel'thugad discovered that the tribe's undead troops were becoming more and more advanced, and the death knights had more and more means, and the captured undead, except for a part of the self-consciousness, the remaining large number of ordinary undead, were faintly following the will of a distant land.Having obtained the Book of Medivan, Kel'thugad tried his best to find the owner behind the undead, so Kel'thugad got in touch with the Lich King Gul'dan.
