What kind of ninth-level spell is the most suitable for rubbing, Lin Yun is not sure, because there are too many ninth-level spells that want to rub up, and any ninth-level spell rubbed onto this ninth-level extreme spell can exert the most extreme characteristics of the spell, not only the power of the eleventh-level spell, but also the power to change the rules.

Lin Yun continued to comprehend the rules, study the Truth Rune, study the Origin Chapter, and even planted the branches of the Eternal Ancient Tree in the southeast of the natural half-plane, waiting for the branches of the Eternal Ancient Tree to sprout, and waiting for this branch to grow into an Ancient Tree of Life, and then continuing to cultivate according to the established plan, maybe he would be able to reproduce the power of the Eternal Ancient Tree, which would be a leapfrog help for the birth of intelligent life in the natural half-plane.

Off-duty, Rena, and the mage legion were all thrown to the battlefield by Lin Yun to experience, and they were all now in the high-speed ascension period, and in this kind of war, it was easiest to improve their level.

The bloodlines of Xiu Ban and Rena have begun to be developed, and they basically do not have any level restrictions at present, they only need to develop the power of the bloodline, and they can continue to improve their level, and the same is true for the mage legion.

The legion mages of the mage legion, since Kurum first advanced to the heavenly rank, there have been people who have followed the advanced heavenly rank, and when all the legion mages have advanced to the heavenly level, the true power of the mage legion will begin to completely enter the outbreak stage.

After all the fifty legion mages have advanced to the Heavenly Rank, the strength they can exert is definitely the strongest existence below the fifth level of the Heavenly Rank, and in this kind of war against the undead, the fifty Legion Mages are tireless killing machines, and the speed of strangling the undead may be second only to the Holy Light Mage of the fifth level of the Heavenly Rank.

Time flies, that is, more than a year has passed, and the Northrend coalition army is almost ready to drive the undead out of the Dirty Blood Domain, and the spatial stability in that passage space is almost completely stabilized, and a month later, it is the best time to open the six-pointed star array.

Ninety percent of the territory in the entire passage space is occupied. Steel fortresses are rooted in this passage space like nails, and in the sky, the magical light like an aurora envelops the entire passage space, and the space here has begun to be separated from the undead plane. It's just the last step.

The more you get to the last step, the more nervous everyone is, and after several years of fierce battles, it is only now that the most critical step is spoken, if it fails in the end. Then the efforts of the Northrend coalition for several years will be completely in vain.

The most important thing is that the passage space can already withstand the power of the ninth level powerhouse of the Heavenly Rank, and when it is completely stable, anyone, any powerhouse can unleash their power wantonly after arriving here.

The Lionheart King, the Forest Elf King, Agaron, and Alonzo had all appeared on the front line at this time to prevent possible emergencies, and Lin Yun also walked out of the natural half-plane, waiting for the final battle.

When he came to the undead disguised as an undead again, Lin Yun finally found something abnormal. The infighting of the undead has all but ceased......

In a short period of time, the intensity of the infighting was rapidly declining, and when Lin Yun walked along the way, he even saw that the army of the undead who were originally fighting fiercely seemed to have received some order, and they stopped fighting and retreated to their own territory.

When he arrived in Ymir's territory, he once again received a large amount of undead essence, so that the ninth-level extreme spell position on the Sage's Chapter really emerged, but Lin Yun was not happy at all.

"Bowdy. Why are you here, didn't Lord Death come? I've received a call from Lord Hunger......"

Hearing Yimir's words, it was strange that Lin Yunneng was happy, and his previous guess was finally confirmed.

Those undead lords are going to have their brains out one by one. After fighting for so long, even if there is no hatred in itself, and now that it is angry, how can it be so easy to stop the infighting.

This is only possible if a truly top-notch undead powerhouse appears, and even if it is a powerhouse of the level of the Bloody Lich. It may not be able to suppress these undead lords, and the most likely thing is that the four knights under the command of the king of the undead have appeared on the battlefield in person......

Unexpectedly, listening to what Ymir said, it seems that the Hunger Knight has arrived, and the Death Knight has also arrived, so if nothing else, the Plague Knight Peg must have also arrived.

The Plague Knight's Scepter and the Plague Heart were snatched away, and two of the four Knights came, and it was even more impossible for the Plague Knight not to come.

All three have arrived, and the last war knight will inevitably come here as well......

Speculate backwards again, the appearance of the four knights at the same time only shows one problem, the king of the undead has awakened, without the order of the king of the undead, how can these four unruly guys who usually fight each other to the death, how can they gather together......

Thinking of this, Lin Yun's face became a little ugly.

The majesty of the four knights under the command of the king of the undead is much stronger than imagined, their appeal to the undead is terrifying, the last time I came, the undead here were still in a crazy infighting, and even saw a forty-seven-level undead being killed by the opponent.

In other words, the last time I came here, the four undead knights had not yet appeared, and only half a month had passed, and the battlefield that stretched for thousands of kilometers had almost returned to calm, and the crazy infighting had stopped.

The deterrent power of the four knights may allow these undead to truly merge together and twist into a thick rope, and the strength that can be exerted at this time will be more than a hundred times stronger than in the previous war.

Not to mention the four four knights at the peak of the forty-ninth level, their strength will not be weaker than the mages of the ninth level of the heavenly rank, maybe they will be stronger in some places.

The plague knight's plague ability, now that he has lost his scepter and his plague heart, it is impossible to release the irresistible plague on a large scale, but this does not mean that the plague knight has lost the ability to release the plague, but he can't directly sweep the entire Northrend coalition with the plague wave as before.

Fortunately, he took away the Plague Knight's scepter before, otherwise, there would be no need to fight at all, and the Plague Knight alone would be able to turn the entire passage space into a plague infected area.

The existence below the Heavenly Rank will be completely wiped out within a week, and within a month, there will be no solution, and the strong people below the fifth level of the Heavenly Rank will all die under the power of the plague.

Thinking of this, Lin Yun felt a cold sweat on his back, fortunately, the Plague Knight had only been a little interested before, and he didn't plan to come in person at all, he just took out the Plague Scepter.

Half of the Plague Knights who have the means of large-scale suppression are abolished, and the other half is based on the Plague Knights' own strength......

But the other three knights are the most troublesome, and the plague knight is the weakest of the four knights, because the power of the plague is useless to the other three knights......

The Hungry Knight, who is said to be a ghoul, and the purest ghoul, is ugly and terrifying, with a head that occupies a third of his body, and has this huge mouth with three rows of interlaced sharp teeth, and it is said that no skeleton of the same level can withstand the bite of the Hungry Knight.

He can devour everything, everything can be devoured and digested by him, before being subdued by the king of the undead, the hungry knight hunts on the undead plane, devouring everything he can see, the emaciated and rickety body, it seems that he can never eat, his limbs are thin and slender, but he has the power to tear everything apart, he is the madman among the undead.

Once the Hungry Knight and the Plague Knight were at war, and this guy could even devour the Plague Knight's plague power......

The war knight was the first to follow the king of the undead, on the road to the king of the undead to conquer the plane of the undead, wherever this war knight wrapped in pitch-black armor appeared, it would be filled with war, and no undead lord was his follower, even in the battle with some undead lords, the army led by the war knight never lost.

The last Death Knight, the origin is the most mysterious, and the only one who has no definite origin, it is said that this guy is the first Death Knight of the Undead Plane, and the only existence that can use the Death Knight as a name.

It is also said that this guy is the second batch of Death Knights, but he killed all the Death Knights, so that all the Death Knights who appear in the future are shrouded in his shadow.

Once the Death Knight also competed with the King of the Undead for that supreme position, but in the end, he was defeated, and the King of the Undead devoured the Death Knight and took another step to become the current King of the Undead.

After the King of the Undead ascended the supreme Bone Throne, he resurrected the Death Knight, and since then the Death Knight has become the number one general under the command of the King of the Dead, which can represent the existence of the will to die......

Thinking of these four knights, Lin Yun's face turned a little green, he had just broken through to the eighth level of the Heavenly Rank in the past two days, and put it to any mage, this speed was terrifying, plus Lin Yun's own strength was much more than that of a mage of the same level, and now the powerhouse of the eighth level of the Heavenly Rank could be his opponent, and he basically couldn't find a few......

But thinking of the existence of the four great knights around him, Lin Yun felt his heart beat faster.

Damn, one is more ruthless than the other, the four ruthless people on the undead plane, pull one out at random, he has a good chance of not being an opponent, not to mention the gathering of the four ruthless people, if he is blocked here, he will definitely die very cleanly.

The four knights gathered together, and none of the mages under the divine fire could be their opponents, especially in the undead plane, and there was absolutely no exception.

If you want to defeat the four knights, you can only fight separately, the four come together, and only the king of the undead can suppress them, and similarly, only when facing the king of the undead, the four knights will bow their arrogant heads.

"Bowdy, what's wrong with you? Do you feel a call? Then let's hurry and go, we can't let the hungry adults wait for me, or we may be devoured ......" (To be continued.) )
