Since he had discovered such a special plant, of course Meng Yuan had no reason to let it go, although Meng Yuan didn't know how they were alive, but it didn't matter, anyway, this was the world of magic, even if he encountered something magical, it wouldn't be surprising. I didn't see that some of the demon clans were still on fire, didn't they live well? So a withered tree or something, it's normal!

But what Meng Yuan values most is that they are not afraid of fire! That's right, Meng Yuan tried to ignite these plants that lived in hell, but no one had any~ So no matter what the effect of these magic plants was, the fire prevention alone made Meng Yuan very satisfied. Therefore, in line with the idea of perfecting his small world, Meng Yuan once again sent an engineering team to start a new round of scraping.

"Trees? Dig it up! Grass? Dig up the land together! What the? Found a new species? Took! What the? There's a demon clan gathering place nearby? Village? Grab them all! Adults read memories, collect blood samples and samples, and the young ones are caught in the small world and assimilated! ”

A month later, it was really a barren place. The demon people who lived nearby disappeared inexplicably, and the not too large Soul Burial Forest was gone, whether it was animals or plants, whether it was big trees or small grass, all of them were gone, and there was nothing left in the original place except for the soil pit that was dug alive into a basin.

And Meng Yuan ran to the Demon Clan's palace, which was the Demon Clan's castle. And the reason why Meng Yuan dared to come here so blatantly was because Meng Yuan was ready to use troops against the Demon Clan.

Now Meng Yuan has hundreds of giant dragons, many of which are higher level seven, such as crystal dragons, purple dragons (magic dragons), poisonous dragons, and holy dragons. And there are a lot of low-end cannon fodder, and all kinds of undead clans are under his army. Of course, in addition to the troops, the biggest confidence that gave Meng Yuan the courage to come here to spread wild was a piece of information, an intelligence of the Demon Clan's use of troops against the underground race. As for the source and accuracy of the intelligence? Of course, it came from those demon clans whose memories were read by Meng Yuan, so there was no doubt about the accuracy!

As early as three days ago, the Demon Clan had gathered most of its forces to launch a frantic attack on the underground race, the reason was that the Demon Clan knew the information that the vitality of the ground race had been seriously damaged, so the Demon Lord felt that this was an opportunity! A chance to completely reverse the status quo of the Demon Clan!

In the perennial war, the underground races have always been sandwiched between the demon races and the above-earth races, so they are also the most damaged. The Demon Race is different, although they also have an above-ground entrance on their backs, it is full of powerful dragons, so the above-ground race has not been able to attack the underground from there, and similarly, the Demon Race has no way to go to the above-earth world through there. Therefore, the demon clan only needs to face the underground clan. In addition, the underground clan has been at war with the earthly races and demons all year round, so in terms of strength accumulation, of course, there is no such powerful accumulation as the demon clan.

Of course, due to the taboo against the above-ground races for many years, the demon clan has not been in a hurry to expand its power in addition to competing with the underground race for resources, and even when the underground race is invaded, the demon clan will go to help. Because the demon clan knows that once the underground race is destroyed, it will be their demon clan next, so the two races have always maintained this half-friend and half-friend relationship.

But now it's different, the Demon Lord found through the spies he planted in the surface world that the earth world has now broken the previous deadlock, the powerful human has lost a castle, and the equally powerful undead have started a death fight with the humans, and then the human race has suffered heavy losses and has to form a new alliance with the elves, and the undead have mostly disappeared except for some remnants.

The most important thing is that now the combined forces of humans and elves are fighting against the forest swamp tribes and barbarian races, so the above-earth races no longer have the extra energy to come underground to fight the autumn wind. Therefore, the Demon Lord felt that this was an opportunity to strengthen the power of the Demon Race, as long as they eliminated the Underground Race, then the Demon Race would completely dominate the Underground World. And taking advantage of the opportunity of the melee between the races on the ground, it is not impossible for the demon clan to rush out of the ground. Even if they can't break out of the ground, then taking advantage of the chaos in the ground world, the demon clan can use this time to digest and stabilize the newly occupied territory and make their race even stronger.

In short, the Demon Clan's abacus is very good, but what they don't know is that the entrance to the ground behind them, which is considered to be very safe, has been opened, and the person who opened the entrance has led the army to the location of their palace, and intends to deal them a fatal blow when the rear of them is empty!

"Ke'er, are our siege troops ready?"

Ke'er said: "Yes, master! Our troops have been prepared, in addition to the magic troops, our technology arms are also ready for war, we have prepared 10,000 soldiers equivalent to the first class of arms, 3,000 people equivalent to various combat vehicles and individual mecha units of the second or third class troops, 500 units of heavy tanks and large mechs equivalent to level 4 or 5, more than 100 units equivalent to the blasphemers of the sixth or seventh class and more than 100 super heavy combat units that you named super large tanks! In addition, we have more than 100 fighters of all kinds to provide air support for us at any time. ”

Meng Yuan nodded with satisfaction after listening to Ke'er's return, you must know that since the first time Meng Yuan used the technology class to attack this world and failed, Meng Yuan had a sullen breath in his heart. You must know that the level of magical civilization in this world is almost the same as Meng Yuan's level of scientific and technological civilization, so why does Meng Yuan's scientific and technological army have to be pressed and beaten by others? Therefore, after a deep review, Meng Yuan found a problem with himself, that is, Meng Yuan had always used the lowest level of troops, and only occasionally used high-level troops. As for the reason? Of course, it's because of the high cost of high-level troops, the long cycle, etc.

It wasn't until Meng Yuan shouted the slogan of fighting the natives and was abused by others that Meng Yuan felt his shortcomings, so he used the past few months to start frantically building high-level troops, and converted all the resources he had accumulated all the time into combat effectiveness, so the above scene appeared.

And Meng Yuan did this for only one reason, that is, to let these natives taste what is called the combination of magic and technology, and what is called the integration of sea, land, air, sky and demons. Of course, the premise is that it is based on the premise that the rear of the demon clan is empty, otherwise Meng Yuan wants to attack head-on? I guess it will have to be developed in this world for a few years!
