For Waldree, the Withered Thorn was not a good thing, and as the species spread, it was she who suffered the most.

However, the Blighted Demon Thorn has a big drawback, only the main material plane can survive, and only if the elements are balanced, they can grow, so Waldrite is also their natural enemy, because Waldrite will drain the elements of any plane, leaving only a pile of waste without nutrients.

But Luo Qiu's words also made Ward Cui very confused, the destruction of the plane cannot destroy the undead creatures, but because of the death of the life race, a large number of raw materials are provided to the undead creatures, and the current billions of undead creatures have given Ward Cui a headache, if the number triples again, it is a torrent that is enough to drown everything.

After being taken by Luo Qiu to visit the new water-based defensive paint, watching a dry skeleton that was fragile and could be broken if he fell, after soaking it into a black armored skeleton that could not be broken no matter how he fell, Wardcui's inner retreat was shocking.

The sheer number of undead creatures was too desperate for a ruler like her to afford to contend with them.

In fact, she is not worried about enemies like the Lord of the Void, because the advantages of the other party are all things that she has a way to deal with, such as the army of the Holy Spirit, she has the Demon Planter Magician to deal with, and the advantage of the void, she can avoid the disadvantages in this regard.

But the huge number of undead creatures is something she can't deal with, and sending millions of demon planter mages across the plane is already her limit, but with the help of the Lord of the Void, Luo Qiu can easily send millions of skeletons.

And the main material plane has a dimensional barrier, she can't take root across the plane through the way of the holy seed like the chaotic plane, Luo Qi is already invincible.

Originally, she wanted to destroy the main material plane by thinning the withered demon thorns, so that it could degenerate into a chaotic plane, so that it could be invaded through the method of holy seeds, and she had done this to deal with the main material plane before.

However, she ignored the identity of Luo Qiu's undead creatures, destroying the main material plane would cause the number of undead creatures to increase dramatically in the short term, and in a few months, she would face billions of undead creatures from the void and directly destroy the plane she controlled.

This is a hornet's nest, if you don't destroy it, you can only watch it respond, but if you destroy it, you have to face the undead swarming creatures, can you survive the dying counterattack of the undead creatures?

At the thought of billions, Waldrey suddenly lost confidence.

After visiting the armored skeletons, Wardtre suddenly asked, "Since there are so many materials, why don't you kill all the creatures at once, but keep them?"

"Of course, it's for the plane barrier, kill all living things, the elements are unbalanced, the plane will be degraded, I sleep in the main material plane in a good way, it's the Lord of the Void who beats me every day, if I can't win, I'll buy me, let me fight you, compared with fighting and killing, I still prefer to sleep." Luo Qiu said in a tone that had once been in the sea.

Of course, if his words were heard by humans and dwarves, he would definitely vomit blood in anger, who caught them and beat them to death every day? The King of Steel Bones has only been in peace for three hundred years, and the last ten years have been tossed again, but the direction of the toss is different.

"Buy?" Wardtrine noticed a key word in Luo Qiu's words, and asked in surprise, "You accepted the Void Lord's employment to come to me for trouble?"

"How can I trouble you? I'm contributing my own strength to protect the plane set we live on, of course, the Lord of the Void has also paid some rewards, and everyone is happy, if it's something that doesn't involve the safety of the plane, you can also hire me, it's not interesting to fight and kill, win-win cooperation is what we should pursue, for example, do you need it?"

After learning what Kim Khora was, Wardtrie almost didn't jump, wasn't this magical item that accelerated the growth of plants exactly what she needed most?

......

After a cursory negotiation of a framework for cooperation, Wardtri gave him a coordinate, asked Luo Qiu to teleport a few bags of Jin Kela's trial packs to this location, and then gave him a way to clean up the withered demons.

The massive mass of roots beneath Triangle City began to shrink and roll back into the ground, rolling from the deepest part of the earth to the ground, and finally rolling into a tree the size of a bowl, burrowing out of the dirt.

The tree was gray and swarthy, with a metallic sheen, no leaves, and all branched branches, like an iron tree made of metal.

Of course, Luo Qiu would not leave it in the ground, but took it out by the roots and transported it to a clearing outside the Triangle City, where countless skeletons were already digging.

A pit with a diameter of two kilometers was dug out, a large amount of soil was filled into the pit, and a small hill bag seven or eight meters high and more than forty meters in diameter was piled up on top of the soil, and then iron trees were planted on the mountain.

In this way, the root system of the iron tree can only spread to the range of the small mountain bag, and if it leaves the range of the mountain bag, it will enter the rest of the soil, and the soil that is planted and died will kill the activity of the roots.

In addition, Luo Gu also built a wall around the perimeter of the mountain bag with Xiyang bricks to enclose the iron tree, leaving only some gaps inlaid with glass, so that sunlight can shine through the gaps and shine on the iron trees.

As for the air, it is filtered layer by layer, and the substances extracted from the ultra-fine fiber seaweed, the filter membrane formed by pressing, and the filter membrane folded into a zigzag structure, can filter pollen and other particles greater than PM2.5, and breathe through the filter membrane to prevent the tissue cells or pollen of the iron tree from spreading into the air.

There is also a mechanism on the top of the iron tree, and there is a large amount of soil on the mechanism, as long as the mechanism is activated, a large amount of soil will be poured down, burying the iron tree, inactivating and killing.

Under such layers of protection, it is ensured that the Iron Tree does not have any possibility of threatening the main material plane.

After doing all this, Luo Qiu was in the mood to wipe the cold sweat that didn't exist on his forehead, but fortunately he scared Ward Cui, otherwise things would be in trouble.

The blighted thorns spread, and it will be very troublesome to clean up, which will cause large-scale death of plants, ecological imbalance, and thus produce a chain reaction, and the final result is that the elements of the main material plane are unbalanced and degenerate into a chaotic plane, this process may be very long, but as long as it happens, it is almost irreversible.

The biggest problem with plane degradation is the loss of the protection of the plane barrier, and if Waldri is not mentioned at that time, maybe the Lord of the Void will not be polite to him.

Of course, these are all things that may happen in the future, and what will happen immediately is that a large number of living races will die, and all living things will become undead creatures, which is what Luo Qiu is most afraid of.

Oh my God, it's full of boring dead people, no production, no consumption, no entertainment, the whole plane is lifeless, and Luo Qiu will go crazy.

Fortunately, Wardtrio didn't know what Luo Qiu was pursuing, and he was really worried about the number of undead creatures skyrocketing, so he gave up the plan to exterminate all species and degrade the plane, and instead accepted Luo Qiu's proposal: You can also hire me, .......

However, compared to hiring Luo Qiu, Jin Kela's effect was more attractive to Ward Cui, and she hurried to verify it.

Luo Qiu had just teleported the sample to the coordinates given by the other party, and soon received the call of the Lord of the Void, which made Luo Qiu chuckle in his heart: Has the contact with Ward Cui been discovered?
