Earlier, Rutherford took Ain and the two of them directly through any door and left the small room in charge of the reception in the town hall. Later, after opening the Lost Lock to stabilize the situation in the city a little, Rutherford summoned Brady to inform him that the destination of any door's teleportation was underground in the Clock Tower.

Because this is the center of the entire Winterfell Locks and some arcane alchemy equipment, and at the same time, Rutherford can better control the changes in the entire magical energy, so the master of prophecy did not choose to leave. When I interrogated Brady before, if I received a message from the Northwest Fortress, I could tell you directly through the teleportation technique.

But things have now developed to the point where there is no way to solve them with teleportation...... At that time, they all thought that the outer guards arranged by each fortress were enough to detect Drew's skeleton army in advance, but they didn't expect this result.

……

"Brady, why are you here?" As soon as Brady pushed the door open and entered the basement, the voice of Rutherford, the master of prophecy, was already ringing.

"Master...... The situation is probably worse than you expected......" Brady's face was gloomy, "Quinton, the commander of Warneburg, has sent a summons, and the skeleton has begun to attack the city. ”

"Siege?" The Master of Prophecy was also taken aback, and even Aine was frightened. Even if Drew and Rutherford had been informed of the accumulation of anomalous magical energy at the same time, and had immediately started mobilizing and summoning, they would not have started the siege right now.

"How long can you keep it?" The first concern of the Master of Prophecy is also this problem, because of the unity of the Northwest Fortress Group, if one fortress is breached, then the role of the entire Northwest Fortress Group will be greatly reduced. It was even reduced to ornamentation.

"According to Quinton, I think it can only support a day or so." Brady shook his head helplessly, "Because Drew's skeleton doesn't know that we can't rely on teleportation to support Warneburg, otherwise ......"

The Master of Prophecy was slightly lost in thought, but Ain, who was on the side, nodded.

"If nothing else, I don't think Drew's side will get any news of the unstable space in a few days." Seeing that Rutherford didn't speak, the mage interjected first.

When the Master of Prophecy heard Ain's words, he asked with some doubts, "Is there any sufficient evidence?" ”

The mage nodded, then shook his head, but didn't say anything. And when the Master of Prophecy saw this action of Ain, he closed his eyes slightly again and began to feel it.

This time, he had blocked the fact that he already knew that space was unstable from his memory, and once again conducted a round of exploration of the space around him.

"That's ...... like this," Rutherford opened his eyes and said with some sighs, "It turns out that this kind of instability has begun to tend to heal, so many unstable points have been hidden in the normal space, and the main world is really powerful and magical." ”

"Then excluding the possibility that Drew may send high-level undead, what is there to hinder now that can speed up the progress of the Skeleton Skeleton's siege of the city?" Seeing that Rutherford was affirming what he had just said, the mage asked again.

"Then there is acid, the acid that was originally used to melt the ashes produced by incineration and at the same time corrode the bone frame, because now this extreme snow has all frozen." Brady said, "Now it's relying on the fire glue and grease to stop the bones through fire. ”

"Acid? What acid? When the mage heard that the acid was frozen, he continued to ask with great interest.

"This ......" Brady was stumped by the question, because he didn't really know the details.

However, Vincent, who had been carrying the instrument on the side, spoke at this time: "I use alum oil collected by condensation during iron smelting, why, does it affect different acids?" ”

"Send a message to Warneburg, I have a way to deal with the acid that has turned into ice." After hearing Vincent's explanation, the mage nodded slightly.

Because this real world is similar to the game, he also knows what the properties of alum oil are, and to put it bluntly, alum oil is the sulfuric acid in the original real society. The sulfuric acid is not volatile, and in a relatively concentrated range, the freezing point is very low, anyway, it is impossible to solidify at the outside temperature.

"There's a way?" Brady was already a little at a loss, but after hearing Ain's words, he suddenly had hope.

"Yes, I've read from a long book on alchemy that alum oil has a very special property." The mage nodded affirmatively, "Just heat these flasks, evaporate two-thirds of the acid, and throw them directly into the trench." Alum oil is the time when it accounts for about one-third of the volume of the entire acid solution, and it is the time when the acid is least likely to solidify. When you just throw it down, it has residual warmth, so you can steam a little more water, because when you dissolve the bone rack, you need to consume alum oil. ”

Although several people in the entire room had not heard of this property of alum oil, everyone knew that alum oil was consumed when dissolving the bone frame, so since there was no way to do it now, it was better to try it according to Ain's method, maybe it would be effective, and it would be able to delay the arrival of support.

"Did the temple inform you?" After arranging for a mage to send this method to Warneburg through a teleportation instrument, the Master Prophecy asked Brady if he had informed the temple.

Brady nodded, and then said, "I have already sent someone to inform me, but now because the archbishop has not gotten up yet, so after the prayer of the temple is completed tomorrow, I will personally go to the temple and visit the archbishops of the various temples to tell them the current situation." ”

The Master of Prophecy still agreed with Brady's approach, so he breathed a sigh of relief, and then narrowed his eyes slightly and said, "Now the result of the instrumental observation is that the magic energy has stopped growing......"

Vincent took Rutherford's words and said to himself: "According to the current situation, it is estimated that in more than twenty days, the demonic energy that should be accumulated will be able to slowly dissipate. ”

Although it was the best way for mages like Rutherford and Vincent to dissipate their magical energy like this, for the situation in the Northwest Province, it was definitely a nightmare for this kind of extremely cold snow to last for nearly a month.

"Master, isn't there any other way?" Brady was deeply upset by the outcome, but he probably already knew that it was the safest and safest way to do it.

The Master of Prophecy shook his head and said decisively, "No." ”

Unsurprisingly, Brady was a little gloomy. After all, the land around Winterfell City is also his fiefdom, and if it snows like this, most of his own people will suffer even more. In normal years, some poorer lords would freeze to death, but now in this extreme environment, it is even more normal. I don't know if those nobles will be willing to share a few gold coins from their money bags this year...... Brady thought.

As the night wore on, Ain collapsed on the table as he couldn't hold on, and the mage in charge of monitoring the instruments changed positions. As for Brady, Vincent, and Rutherford, they are strong and do not rely much on rest to recover their energy. Although there is not enough rest to recover their depleted spell slots, for spellcasters like Vincent and Rutherford, a few less spell slots in the lower ring will not hurt.

But there was a fierce struggle in the ditches outside the city of Warneburg, inside and outside the walls, until the sky was slightly bright, and it was another dawn.

Quinton looked at the slightly revealing sun and sighed with emotion: "Perhaps, this is the last few suns we have seen......
