Roland moved his quill, quickly writing lines of text on the paper.

Before coming here, he spent his days drawing mechanical blueprints in front of a computer. He thought he would rarely have the opportunity to write with a pen again, but he didn't expect to be using this ancient way of recording things again.

Beside his hand were two documents, both of which were plans he intended to implement next.

One was the large-scale production of sulfuric acid. The new equipment had already been manufactured by Anna and Soroya. The lead reaction vessel was replaced with a more sturdy and reliable iron shell, with an anti-corrosion coating on the inside, three times larger than the previous experimental version.

Considering that at this stage there was no way to collect or purify production waste gas (mainly from sulfur combustion and leaked nitrogen oxides), Roland set it far away from the Redwater River and residential areas – the southern end of the industrial park. He also planned to build a factory around the reaction device for isolation, and erect chimneys to increase the height of exhaust emissions.

Since increasing sulfuric acid production greatly helps to expand the scale of nitric acid production, putting the equipment into production was the most important task at present. The content on the document was to order Kaimo. Streel to select a group of disciples to specialize in the mass production of sulfuric acid. Barov also needed to recruit some reliable local residents to serve as auxiliary handymen. The first phase of the chemical plant would have about a hundred people.

The second document was the establishment of a public healthcare system.

To be honest, Roland wasn't familiar with this area. He didn't know anything about modern medicine, but this didn't prevent him from formulating a simple plan that met current needs based on common sense.

First of all, the biggest role of this department was publicity and popular science, such as boiling water before drinking, cooking meat thoroughly before eating, the causes and solutions of diseases, the difference between parasites and microorganisms, etc. Thanks to his growing prestige, it wasn't difficult to get the people to do something as required, but to make them understand why they should do it, someone had to be dedicated to promotion and education. Telling them once was useless, so he would repeat it seven times, dozens of times, like the slogans hanging in the fields. If he said it often enough, everyone would slowly accept this view.

Secondly, it was to encourage childbirth – the city hall had limited manpower, and he didn't want to set up a separate family planning department, so he temporarily included this in public healthcare. Population was always the most scarce resource in this era. It would be best if the people could have more children. Nana's ability even made up for a series of tricky issues such as production risks. With her, the postpartum survival rate could almost reach 100%. In addition, in order to avoid events such as abandoning baby girls and only giving birth without raising them, he formulated detailed subsidy and punishment policies, such as subsidies for baby girls being slightly higher than for baby boys, subsidies being paid in installments, and abandonment of babies facing fines and imprisonment, etc.

The last point was to be responsible for charging fees. In addition to fertility treatment, the medical institute would charge a certain fee based on the amount of magic power Nana consumed, which was both to reduce the burden on the little girl and to lay the foundation for the future hospital system. Roland had already thought of the first head of the department, namely Nana's father, Tigu. Pine Viscount.

The third document was the one he was currently writing, which was also the most complex and extensive of all the plans – the Border Town construction plan.

It involved the implementation of the town's own expansion and the merger of Longsong Stronghold. At that time, a series of common laws would definitely be promulgated to govern the people of the two places, and the judicial system and the public security system would also have to be added. It was definitely not enough to write these contents flawlessly based on his own knowledge. Roland planned to first list a draft, and then discuss and improve the other details with the city hall director, Barov.

After writing the opening part, he moved his slightly sore wrist and walked to the floor-to-ceiling glass window.

The weather today was very gloomy. He didn't see the sun in the morning, and by the afternoon, the sky was covered with dark clouds. It seemed that a heavy rain was brewing. The slightly chilly autumn wind swept across the castle's back garden, and he could hear the rustling sound from the olive grove.

At this moment, a black dot appeared in the sky and flew towards the castle.

"It's Lightning," Nightingale's voice came from behind.

"Probably going to the Misty Forest to pick mushrooms again," Roland said with a smile. Usually, when there were no reconnaissance missions, Lightning and Maisie's practice was completely free flight, so not returning to the castle for lunch was normal. According to the two of them, they often poked some bird eggs and beehives in the woods, or caught some strange little animals to roast and eat. Perhaps the final form of explorers would all turn into Beiyes.

In addition, although the Bird Kiss Mushrooms basically grew on trees, he always couldn't help but think of the "Little Girl Picking Mushrooms" story.

"Your Highness, you... are smiling strangely."

"Ahem, I thought of an interesting little story, do you want to hear it?"

"Hmm?"

Roland cleared his throat, "Once upon a time, there was a little girl who liked to count while picking mushrooms... Wait." The black shadow was getting bigger and bigger. Unexpectedly, the other party did not pass over the castle, but lowered its altitude and rushed straight towards the office's floor-to-ceiling windows. Roland was stunned for a moment, then reached out and opened the window. Lightning rushed into the room without hesitation.

"Your, Your Highness!" She shouted excitedly as soon as she landed, "I found a witch!"

"A witch?" Roland asked curiously, "Where?"

"In the stone tower in the Misty Forest," Lightning pointed to Maisie, who flew into the office afterward, "She can testify!"

"Coo!" Maisie looked up and said.

"Stone tower?" He frowned, "What exactly happened? Tell me in detail."

After listening to Lightning's description, Roland couldn't help but gasp. This guy was too bold. He actually dared to explore the ancient ruins where demons existed again with a pigeon. But what was even more terrifying was that a witch was actually sealed in the ruins? Of course, it might also be an ordinary person sealed by a witch... Anyway, this was an incredible piece of news.

"What's with the cries for help?"

"It's this thing. I found it on the table behind her," Lightning took out a palm-sized square iron box from her pocket. At first glance, it looked like a small mirror used for makeup. Opening the lid, he saw that there was a red gemstone inlaid inside. She moved the trigger next to the gemstone, and an anxious female voice suddenly appeared in everyone's ears.

"Save me..."

Roland shuddered suddenly. This voice was sometimes near and sometimes far, and it was really creepy. If he heard such a cry for help in a dark basement, he would definitely turn around and leave without saying a word.

"There is magic power in the gemstone," Nightingale appeared, marveling, "I can see a faint vortex of magic power, just like the operation in a witch's body."

Okay, it seems to be a magic recorder that can continue to make sounds. The possibility that the other party is a witch has increased again. "Are there any other such stones in the basement of the stone tower?"

"I didn't look carefully. Many places in the room were flooded," Lightning shook her head, "At that time, I just wanted to come back and tell you the news as soon as possible."

"Don't do this again in the future, especially going to dangerous places without permission," Roland patted her head, then looked at Nightingale, "Summon all the members of the Witch Alliance and Iron Axe to the office. The plan to search the ruins may have to be brought forward."
