On the top of the mountain, the wind was very noisy.

The vegetation in the saline-alkali land is already sparse, and there has not been a trace of raindrops falling recently. The withered ground is covered with dust brought by the wind to the top of the mountain from time to time.

Auston I stood alone on the top of the mountain, and his servants were driven to the foot of the mountain by him. He was holding the drawings and needed to think about the problems encountered in the ongoing water conservancy projects on this land.

Although the soldiers who are working as laborers are full of energy inspired by the good news of obtaining the land's right for a hundred years, the lack of drinking water has seriously dragged down the progress of construction.

Wells can also be dug here, but the well water is bitter. After boiling, you have to filter out the scale in the water before drinking. Even so, the amount of water burned every day is limited.

If Auston I hadn't set an example and drank the water here with everyone, the soldiers would have been passive and slackened.

It has been a month since he pulled the army here to work, and the water canal has been basically completed, but the progress of the artificial lake used to store clean water is not a little behind.

"The progress is not enough, and it is best to dig deeper this lake so that the groundwater can be washed in the shortest time."

Auston I nodded after hearing the sound coming from his side. He could feel that the uninvited guest who suddenly appeared beside him was very strong, but without any malice.

"What are your opinions? Can you give me some advice?" asked Auston I.

"Give me ten ole, I promise that the construction of this artificial lake can keep up with the progress." The uninvited guest said confidently.

Auston I took a beautiful dagger from his waist and handed it over, saying, "If you don't bring cash, just use this to settle the bill, how about it?"

"No problem." The uninvited guest took the dagger, "But it's better that you need to cooperate with this matter, you just need to do this..."

The uninvited guest left, as if he had never been there, with only a black line on the top of the mountain, and the noisy dust.

"Calcium oxide! Why didn't I expect this trick?" Auston I was so depressed that he stomped his feet, then took out his pipe and smoked.

A few days later.

In the city of Sepas, the capital of the Kingdom of Reyrik, this summer is particularly hot, and cicadas are chirping on cypress trees everywhere in the city.

In a luxurious living room, the ice magic circle on the wall made the house cool enough. The two old men were sitting on their own sofas, one closed their eyes to rest, and the other quietly looked at the garden outside the window.

The living room door was suddenly pushed open, and the owner of the house, Earl Rank, walked in with great strides.

Rank said anxiously to the guest who had been waiting for him in the living room for a long time: "Saxony, Palatinate, I know what's going on."

The Marquis of Saxony, who had been closing his eyes, opened his eyes, looked at Rank steadily, and the Earl of Pafalz, who was watching the garden, also looked back.

The servants handed the master tea at the first time, and Rank picked up the teacup and drank it all in one sip.

The weather outside was too hot, and the elderly Rank couldn't stand it.

After putting down the empty tea cup decorated with the four demon characters "Flowers bloom and prosperity", Rank finally breathed a sigh of relief.

"Today His Majesty the King invited me to come over to let me identify a few old antiques." Rank said to the two old friends.

This morning they were gathered together to discuss the matter of Auston I pulling his army to the saline-alkali land to dig holes, but soon Rank was invited to the palace by Auston I.

Paladin was a little curious about this, and he asked, "What kind of antique is it that we actually need to invite our great scholars?"

"You guess." Rank looked at Palatinate with a hint of provocative expression.

Palatinately became interested. For decades, whenever Rank asked them to guess things often meant something good was going to happen.

"Did you dig it out there?" The first answer was Saxony.

"That's right." Rank picked up the tea cup where the maid filled the tea again. "Today, my Majesty invited not only me, but also a few old friends from the Knowledge City."

Pafalz and Saxon watched as Rank drank another cup of tea, quietly waiting for the following.

In addition to being a nobleman, Rank is also a famous historian and has special research on the history of the demons.

"It's a pity that Professor McGarden has passed away. If he were still alive, he would definitely be happy to see those antiques." Rank sighed.

Pafalz and Saxon were stunned. Since Rank mentioned his teacher back then, it means that this matter is inseparable from the demons.

Next, Rank didn't keep it a secret, saying: "That was a weapon used by the Demon Guards hundreds of years ago."

Paladin said in confusion: "But the demon army has not arrived in the east for almost a thousand years. Could it be that it was left by Ekaterina?"

Rank waved his hand, and all the maids in the living room withdrew, leaving only the three of them.

He lowered his voice and said, "That's a long-standing history. I believe everyone has heard of a war in the Knowledge City five hundred years ago."

Pafalz and Saxon nodded. They had heard of this history, but no one knew the cause and effect.

Rank said: "According to a confidential historical record, a brave man brought back the weapons used by the Virgin Mary, who was worshipped by the demons, and stored them in the Knowledge City."

"Later, the demon clan sent a large number of people to rob the weapon back. However, the troops sent by the demon clan were wiped out by us humans, but in the end, the demon clan who escorted that weapon disappeared together with the weapon."

Saxon's eyes showed a greedy light and he asked, "Can you be sure that the weapon is hidden in that piece of land?"

Pafalz's performance was not much better, but he still took a scruple and said, "Is it just a coincidence that those weapons were just dropped by chance?"

Rank said: "I thought about this problem on the way back. If only a few weapons are found, it doesn't mean anything, but if a large number of weapons are found..."

The three of them looked at each other and each had a guess.

Palatinate thought and said, "It seems that our Majesty has obtained some clues, otherwise he would not have paid so much attention to that saline-alkali land."

Rank agreed, "Yes, Your Majesty had a special concern for places where weeds can only grow, or even weeds, and I'm afraid this was planned by him many years ago."

"Let's help your Majesty," said Saxon. "There's not much water in that place."
