Of course, among all the devouring things, it is the most efficient to use the flesh and soul of the monk. After all, mountains, rocks, civil engineering, and the like contain very little spiritual energy, and even if it is a spiritual stone, spiritual material, or even a spiritual vein, the spiritual energy contained in it is not as pure and abundant as the spiritual energy accumulated by the monk for thousands of years.

Therefore, for the Heavenly Dao of the Demon World, the best and fastest way is to devour the flesh and blood of the monk, of course, this is only for the dead monk. Because the living monk has a very strong ability to control his own aura, it is not so easy to be swallowed and absorbed.

Of course, this is not to say that the "Demon World Heavenly Dao" does not even have the ability to forcibly absorb and devour a low-cost monk, but in that way, under the full resistance of the other party, it will consume a lot of energy to suppress the other party. It even consumes more energy than you get, so it's a bit more than worth the loss.

Therefore, the "Demon World Heavenly Dao" will not hesitate to consume a large number of original sources to cultivate the "Demon Race", and ask them to kill for themselves, and one energy may be exchanged for two, three or even ten hundreds. Taking 10,000 steps back, even if these demons are killed, they are just reabsorbing themselves, and they can't lose too much.

However, now there are no fierce beasts to attack the "Demon Race" that has passed through the "Demon Passage", so there will not be so many cultivated creatures and flesh to absorb him. As for calling "Demon Soldier" to send death to provide energy again, it is also an emergency method that will only be used in extraordinary times, if there is no limit to use, all the energy is used to build "Demon Passage", there will not be enough manpower to resist the opponent's counterattack and expand the territory for him.

Now that the "Demon Realm Channel" wants to be reinforced, the energy required can only be absorbed and devoured from the area he is shrouded in. It's just that this is much slower, don't look at the "Demon Realm Passage" in just over a month, it has been upgraded to the level that the God Transformation Stage can pass, but don't forget that it consumes tens of millions of living beings and flesh.

But now, it is a very limited thing to rely on this is only a few thousand miles in circumference, and it is not a spiritual stone vein or a giant spiritual vein, but it is a very limited thing to extract spiritual energy just from ordinary mountain and stone land, and even basically there is no effect.

But that's the case, within that thousand miles, the grass and trees have long been turned to ashes, the insects and ants are extinct, and there will not even be a lonely ghost anymore. ("Demon World Heavenly Dao" is very aggrieved, tens of millions of monks in your family have been fighting here for a month, and it's strange that these are not dead.) These are really nothing, and the most unbearable thing is that if you look closely at this thousand miles of circumference, you will find that everything has been completely changed.

The first is that all the ups and downs of the terrain here have disappeared, all the original peaks and rivers have disappeared, and the rocks have turned gray-yellow powder. If you look closely, the riverbed still exists, but it has dried up. And even if you take a closer look at the earth, you will find that it is a lifeless appearance.

As long as you have a little experience, you will know that such a land is already "Dead Land", and there will be nothing to grow on it, and the reason is that such a land no longer has the slightest aura.

As for the air, at this time, there is not the slightest trace of the aura of travel as strong as that of ordinary places. The reason is naturally that the travel aura within a thousand miles has been swallowed up. However, the strange thing is that the aura in one place was absorbed too thinly, and the aura in other places was replenished, but this time the aura in the air thousands of miles away was still rich, but there was no trace of aura replenished.

This is naturally the counterattack of "The Heavenly Dao of the Sin Universe World", after all, it is most appropriate to fight against the "Heavenly Dao" or the same "Heavenly Dao". It is the "Xingzhou Heavenly Dao" that controls the surrounding aura to replenish the range of thousands of miles, so where will it become the aura vacuum zone.

Not only that, if there is a scattered immortal level who comes here and carefully observes with a powerful divine sense, you will find that not only the aura in the air, but even the aura contained in the earth is slowly retreating backwards, and the closer you get to the "Demon Domain" (the area covered by the Demon Heavenly Dao, hereinafter referred to as the "Demon Domain") is the more and more the aura is getting thinner.

However, "Xingzhou Heavenly Dao" doesn't seem to be good at completely extracting all the spiritual energy, and there is still a lot of spiritual power left in all places. This is related to the style of "Sin Chew Heavenly Dao" that leaves a glimmer of life in everything, but "Demon World Heavenly Dao" is even more extreme in doing things, leaving no room for anything.

And "Demon Domain" will naturally not be limited to a mere range of thousands of miles, but there are constantly new "Demon Clans" swarming through "Demon Realm Passage". These, the demons are constantly planting new large and small "Demon Heaven Introduction" magic array arrays, so that the "Demon Domain" continues to expand its scope.

And such a big fluctuation here has already spread throughout the entire "Sin Chew World", and it should even be said that when the "Demon World Passage" just connected the "Demon World" and "Sin Chew World", it was already sensed by "Old Huluzi" and others.

In fact, in these last decades, the demon race and the human race almost all of them were together. This is so that once the situation is discovered, you can attack at the same time as quickly as possible, so that you have enough strength to block the first wave of "Demon Clan" invasion attacks.

This is to learn from the experience of the last "Demon World Invasion" power dispersion, for this reason, everyone spent a lot of manpower and material resources to find the record of the last "Demon Invasion", but unfortunately the time is too long, and the income is really very limited.

However, although this time they sensed the opening of "Demon Passage", everyone repelled each other. After thousands of calculations, no one would have imagined that "Demon Passage" would be opened in "Flood Land".

In this way, not to mention that the team of centaurs will kill in the past, will those fierce beasts who do not have enough intelligence to like to kill cooperate. The distance alone was too far away, making it impossible for them to rush there in the first place to stop the first batch of Demon Troops.

You must know that last time, it took them several months to get to the place where the "Hongqiao Immortal Mansion" was, and at that time, only a few of them could carry the rest of the disciples with poor cultivation and go at a relatively fast speed.

And this time, although everyone's cultivation has made a breakthrough, what they had to fight against at that time was "Demon Army", so they must bring enough people to go. After all, against the army, it is still the army that is the most suitable, and no matter how high and powerful a single person's cultivation is, it is beyond the reach of the power, once the strength is exhausted, the high-level monks can only be slaughtered.

Fortunately, now that the armies of the human race and the demon race have been assembled, the human race is guarding near the "Mausoleum of the First Emperor", after all, there was a small "space crack" leading to the "Demon World" before. And the army of the demon clan is near the place where the last "Demon Passage" appeared. These two places are actually the places where they expected the most likely appearance of "Demon Passage".
