In the dark passage, the team composed of mages and meat shields, while vigilantly looking at the mud warriors around them, cleaned up the demon devouring rats that rushed up from time to time, except for the low-level demon devouring rats that appeared at the beginning, to the higher and higher-level demon devouring rat leaders in the back, and the demonic beasts outside the city were attacking from the underground passages, fortunately, the passages were narrow and those huge high-level demonic beasts could not enter, otherwise the consequences would be unimaginable.

Bancroft frowned, "The passage here must be destroyed as soon as possible, and we can't wait for these burrowing demon eaters to destroy the foundations of Blizzard City." ”

Long Tianyou knew that this passage was the passage of the last decapitation mission, and it seemed that it was the aftermath of the last operation, and he still remembered the heroic sacrifice of the soldier when he saved people.

Whirring, the scorching fire dragon roared past, leaving a passage roasted by the fire, and the red-haired old Able eliminated a large wave of demon eaters: "The more and more garbage is cleared underground, you have to think of a way to stop them." "The old man is very irritable, like an ant, it bites you and doesn't die, but waves of harassment and annoyance are annoyed to death, for these hurtful problems, it has always been his old buddy who gives advice, and he is only responsible for contributing.

Bancroft threw a tornado over, the ashes of the underground demonic beasts were swept away, and the hot air of the passage also brought a little coolness, and the entire passage was dug out of large and small caves, and from time to time a demon eater rat or something would come out of it to make trouble.

"This underground has been hollowed out, it is not ideal to clean it up purely by manpower, if the strength is low, it will be sent to death, and the strength of the high strength will not be able to be displayed in this terrain, we should go back and report to the Operations Coordination Department first to see if they have a better idea. "Bancroft has no choice but to retreat to the ground first, then seal the passage here, and wait for the people above to come up with a solution.

The three of them returned to the ground with a disgraced face, and the demon eater rats on the ground were almost cleaned up by the army, which benefited the young man to attract most of the firepower before, and then the two high-level magicians made the soldiers behind them much less resistant, and the successor demonic beasts were also blocked by them, and it was easier for the soldiers to clean up the demonic beasts.

"Report to the sir, the demonic beasts on the ground have been cleared, and I would like to ask the two lieutenant generals to instruct the next step. "A military officer came to ask for instructions.

Long Tianyou can be regarded as not knowing the titles of the two high-level magicians, he can't be so clumsy.

Bancroft said majestically: "You lead the army to guard here, you must block the demonic beasts here, no one is allowed to retreat half a step without my order, I will report the situation here, see how the above arranges." ”

Old Abel turned to the young man and winked his eyebrows, as if he was triumphant and silent, and said, "Look, Lao Tzu is a senior officer, and you little soldier must be obedient."

Long Tianyou pursed his lips and pointed to the burned clothes on his body, you still owe me a piece of clothing, and the shortcomings were revealed, and old Abel was deflated at once.

In the end, Bancroft flew away quickly, he was a wind mage, and his speed was the fastest of all, so it was up to him to report the situation as quickly as possible, and the old Able stayed behind to guard in case something unexpected happened.

Why did it suddenly become quiet, this is a bit strange, the young man thought secretly.

The Demon Eater rats, which had been in an endless stream, no longer came out of the hole, Long Tianyou also had to be idle, and the demonic beasts on the ground were also swept away, which was originally a fortunate event, but intuitively, the boy always felt that something was wrong there.

At the same time, thousands of meters underground in the center of Stormwind City, the demonic beast ore veins that protect the formation energy for the whole city, click, click, countless demon devouring rats are happily gnawing the magic crystals underground, and I don't know how they bypass the heavy protection, they are destroying the core of the city's magic circle at an alarming speed, Blizzard City's strategic reserve of the magic beast core is not wrong, but the tenth-level demon beast core can only provide energy for the protection formation of the whole city of Blizzard for a short time, and the magic crystal veins under the ground are the real power energy, just like the foundation and pillars of a house, and the magic crystal veins are the foundation of Blizzard City。

Oops, feeling that the energy output of the central magic array began to be unstable, and even greatly decayed, the face of the old magic array master who was guarding the magic array changed drastically, and almost instantly, under the extension of his magic power, he sensed the dense destroyers underground.

While the old magician tried his best to maintain the output of the formation's energy, and more high-level magic crystal cores were invested in the energy conversion node without money, he urgently summoned the city lord of Blizzard City, and about five minutes later, all the main decision-making leaders of Stormwind City gathered here.

"Master Angelo, what's the situation here now?" Just received the bad news of the Demon Eater raid in the city, and before he could react, the city lord Archibald received even worse news, and he didn't even have time to listen to the detailed report, compared to the casualties of the Demon Eater raid and the crisis of the city break, which was more important and obvious.

"The underground bed of the Demon Crystal Vein is being destroyed by unknown creatures, if we don't want to find a way to stop it, it will take about half a day for the protective magic array in the city to rely on the Demon Crystal Core to maintain its operation, the first city lord of Blizzard City chose to establish Blizzard City here, a large part of it is because there are huge magic crystal veins underground.

In fact, the underground magic crystal veins are also protected by a layer of magic array, and there are also layers of physical defense, but no one would have thought that these mutated demon eaters who feed on magic crystal energy, all energy-related protection is as fragile as tofu.

And the most terrible thing is that because the Demon Eater Rats are thousands of meters deep underground, there is nothing that can be done about the destruction of them by humans on the ground, and no matter how strong the attack is thousands of meters underground, the lethality can be negligible.

If it's forbidden magic, it's fine, but if that's the case, the forbidden spell will also destroy everything on the ground, which is an unsolvable knot. Even the builders who originally designed Blizzard City didn't take into account the current situation, after all, large-scale energy-feeding monsters were extremely rare and unheard of.

The old magician has elaborated on the current predicament, but no one has been able to offer a solution that works.

"May I ask Master Angelo, if the veins of the magic crystal under the ground are destroyed, how long can the energy reserves on the ground be maintained. "Admiral Yarman has to consider the worst-case scenario, he is a soldier, and a soldier has to think about the whole situation from the facts.

"If the worst happens, the reserve of the Treasure Crystal Core may last for three months, and considering the current situation and the consumption of the attack circle, it may not be able to hold out for a month. "The old magician gave a disappointing statistic.

"Prepare for a strategic evacuation, I'll leave it to you here, and I'll go back to the military headquarters to come up with a plan for retreating. Admiral Yarman said coldly, as the top person in charge of the military department, he can't have a fluke mentality.
