After making a decision, Emperor Shi Tian was also resolute, and immediately sent all the Flawless Soul Crystals in his hands down, and asked them to quickly retreat and advance.

Immediately afterwards, Emperor Shi Tian personally supervised his subordinates, carefully searching the looted land and the various alchemy buildings on it, wanting to see if more Flawless Soul Crystals could be found?

Of course, the Flawless Soul Crystal is not easy to find, and there is no trace of it for a few days anyway, but as the lair of a high-level demon lord, there must be a lot of good things in it.

Gold-level alchemy buildings, there are thousands of them in each nest, and even legendary-level alchemy buildings must be there, and there are quite a few. If you add it all up, there can be dozens or even hundreds.

There is no doubt that all of these are very valuable resources.

A small half of them are all kinds of biological nests, and another half is all kinds of precious resources and minerals, and the rest are messy things, but they are also very useful, and there are almost no ones that cannot be used.

However, just a few days after Emperor Shitian Meizizi was searching for treasure, a piece of bad news came from the front line.

As the saying goes, if you walk too much at night, you will eventually encounter ghosts, and Emperor Shi Tian will be unlucky to step on thunder this time.

In fact, he blamed him for underestimating the wisdom of the demon lord, and when he launched the left and right hook plan, he thought about developing from the middle to the sides, although some less important battle zones would be jumped away, but the general direction was extended to both sides in order.

As a result, the family found out the pattern, and then there was a very powerful and clever demon lord who felt that he was likely to be the target of a sneak attack, so he took precautions in advance.

This sage-level Fire Demon Lord pretended to send a large force to attack the defense line of the Heavenly God Academy, but in fact, the troops he sent out were nothing more than cannon fodder, and most of them were illusions created by spells.

Of course, these illusions are all behind, and there are real troops around to protect them, so they who did not directly participate in the battle were not found to be abnormal by the defense forces of the Heavenly God Academy.

After all, this matter is too unusual, the defense forces here have been fighting with demons for thousands of years, and they have never seen demons dispatch phantom legions to conduct deception operations.

As a result, their carelessness at this time created a lot of trouble for Emperor Shi Tian.

After Emperor Shakti's doppelganger received false information from the front-line troops of the Heavenly God Academy, he mistakenly thought that this guy had transferred the main force to the front line, and the nest in the rear must be empty.

So according to inertia, without much careful inspection, he stupidly led thousands of horses and thousands of troops to kill the past.

After the spatial rift opened, the army of the undead, which was as wide as 100,000 miles, slaughtered the opponent's lair like a tsunami.

At the beginning, the fire demon's troops did seem to be underarmed, and they also seemed to be taken by surprise, so that the mobilization was chaotic, and they were completely unable to resist the attack of the undead tsunami, and they were defeated and retreated.

Many of the Fire Demon Castles were overwhelmed by the undead, and they had to rely on the complex terrain inside for their last resistance.

In general, this resistance is futile, and as long as the external situation does not change, the little strength inside will sooner or later be eaten up.

This time, however, the external situation has indeed changed.

Just when the army of the undead was about to enter the hinterland of the opponent's Chinese army, suddenly, a series of fiery red demon teleportation arrays began to flash in various places of the lair out of thin air.

With each flash, thousands of demons suddenly appear in place.

If these demon teleportation arrays are behind the demons, then the teleported demons will immediately assemble and form the same tsunami-like scale, and in turn press down on the army of the undead.

And if these demon teleportation arrays are in the place occupied by the undead army, then they will immediately launch a fierce attack on the surrounding undead, directly catching the undead troops off guard.

Although they simply won't last long, they will be drowned by the sea of the dead again.

But they also bought precious time for their side, and the teleportation array behind them was still operating, and tens of thousands of undead troops were constantly teleported over.

As a result, the speed of killing in the Sea of the Undead could not even catch up with the speed of the opponent's reinforcements, so that these demon forces became more and more numerous, and they also happened to be located in various transportation arteries and near the demon castle.

Obviously, it is impossible for a force that can teleport so quickly and on such a large scale to be in the abyss plane.

Teleporting across planes is particularly expensive, and the speed of teleportation is relatively slow, so it is impossible to do so quickly.

So there is only one answer, these troops must be hidden in a nearby place in advance, and it may be in some special space in the demon castle.

And those teleportation arrays were also buried in the lair early on, and they were also buried deep and concealed, so they could avoid the detection of necromancers.

It is very obvious that people are planning to plan and design a trap for Emperor Shi Tian.

Judging from the size of the opponent's troops, as well as the consumption of the teleportation array, this is beyond the ability of an ordinary high-level demon lord.

Especially the troops that the other party teleported to the back of, there are basically at least three or four layers, all of which are high-level troops above silver, and there will even be legendary demon suppression arrays.

It is precisely because of these strong existences that they can still stand firm under the continuous impact of the sea of undead.

If they just rely on numbers, the legendary mages hidden on Emperor Shitian's side will definitely teach them how to behave.

In fact, after seeing that the situation was not good, the front-line commander on Emperor Shitian's side had already ordered the release of legendary spells regardless of losses.

You must know that these guys are in the hinterland of the Sea of the Undead, and the area covered by legendary spells is often a few kilometers or even a dozen kilometers, and it is difficult to control accurately.

So if you smash it like this, no matter how much the other party dies, you will definitely be injured a lot by mistake anyway.

But no one wants to injure their own people by mistake until they reach the point of exhaustion, and in any case, it can be seen how bad the situation at the front line is.

However, even if Emperor Shi Tian's side had already gone out and smashed the legendary spell into the hinterland of his undead sea, the result was still not optimistic.

Because most of the legendary spells were blocked by the opponent's legendary masters, they only caused a small amount of damage to the opponent's troops, and basically did not hurt the overall situation.

Only a few legendary spells exerted their due power, directly emptying a piece of land within a radius of about ten miles, whether it was the enemy or their own people, they were completely blown to pieces, and even the ground was cut several meters.

But even so, it still didn't hurt the opponent's teleportation magic array, and with one teleportation light after another, the cleared land was once again filled with a large number of demons.

Emperor Shi Tian estimated that the opponent's magic array was likely to be hundreds or even thousands of meters underground, and it was not easy for legendary masters to destroy them, at least not something that could be done by a few legendary spells.

Of course, if the other party just made such a move, Emperor Shi Tian's army of the undead would not be afraid at all, wouldn't it be more than humans? Who is afraid of whom?

Although after several successive wars, the bone frame on Emperor Shitian's side has also lost tens of millions, or even hundreds of millions, but it can't stand the speed of other people's production?

To build a bone shelf, as long as there is enough magic, enough bones and enough necromancers, there is no shortage of the Emperor of Heaven.

In addition, the Seven Sovereigns of the Undead themselves are extremely powerful in military strength, and with hundreds of thousands of years of savings, even they themselves don't know how many undead troops they have.

In this case, Emperor Shi Tian is absolutely confident to use his troops against any demon lord.

The big problem is that those high-level demon lords are not idiots, they have already found out the information that the Seven Monarchs of the Undead have returned to Emperor Shitian, and they know that the number of this guy's undead troops is too large to count, and he is not afraid of loss at all.

Therefore, in view of the advantage of Emperor Shitian's strong forces, these high-level demon lords were definitely out of the way, and they were stunned to make a super giant divine weapon.

This is the first time that Emperor Shi Tian has seen the legendary super giant god soldier on the battlefield, but it is a pity that he is the one who is threatened.

The super giant divine weapon prepared by the other party was a type that Emperor Shi Tian had never seen or heard of.

To put it simply, it resembles a giant red slime with a cone-shaped volcano on its head that is not much smaller than his body.

So how big is this slime? Emperor Shi Tian estimated that if this guy was a standard spherical shape, it would definitely have a diameter of more than 3000.

Although the volcanic pressure above his head was a little flattened, combined with the height of the volcano hat itself, the height of the thing reached more than 3,500 meters.

This thing is different from other super giant gods, other super giant gods will use their size advantages, with super huge weapons, to sweep or hit the troops on the ground, without casting any spells, they can create no less lethality and coverage than legendary spells, so it is also known as a legend!

This means that every move is a legendary spell!

This slime obviously has no arms and no weapons, so it has no normal attacks, and it looks as if it has lost the terrifying lethality of the legendary move.

But in fact, it is not the case at all, because this slime is simply composed of ultra-high temperature semi-liquid metal, and the temperature in the body does not know how much, anyway, the temperature on the body surface is at least seven or eight thousand degrees or even tens of thousands.

Metal, on the other hand, is the easiest to dissipate heat to 4 weeks, so this guy is not at all.

When he was 100 meters away, the temperature was still above 5,000, and within 1 kilometer of him, the temperature was about one, two, or three, and he could basically melt steel.

Only a range of more than 2 kilometers away from this guy can barely keep ordinary troops alive, but in fact, the temperature at this distance is more than 100, so the water here is completely in the form of steam.

All in all, even an ordinary silver-level class is not qualified to be within 1 kilometer of him at all, so this guy's own lethality and killing area are definitely not inferior to legendary spells.
