The Hero Who Troubles the Heroes

In the afterglow of the sunset, Nicholas II left Jesse Mack's farm with a sound of Charles "biu", and then appeared in a garden surrounded by buildings with green walls, white columns and green roofs .

There are many plants in the garden that Charles has never seen before, and the wind carries moisture.

The guards who were facing the enemy only lifted their fighting status after confirming that the person who came was Nicholas II, but their eyes fell on Charles.

After Charles left the garden with Nicholas II, a young guard asked the person beside him in a low voice, "Captain, is that child your Majesty's..."

"Don't talk too much, how can you talk nonsense about His Majesty's family affairs?" His captain stopped him from going on, "Just know some things yourself."

Nicholas II took Charles into the buildings around the garden, only then did Charles realize that it was a magnificent looking palace.

There are crystal lamps on both sides of the corridor, oil paintings protected by golden frames are hung on the white walls, and there are exquisite patterns depicted by gold paint on the white ceiling.

A silver-haired, red-faced human maid in a maid's costume was already waiting there. She bowed and saluted when she saw Nicholas II coming, "Welcome Your Highness back to the palace."

Nicholas II said to her: "Prepare me a dinner, bring it to my office, and prepare him a drink. He has eaten dinner."

Then he continued pointing at Charles and said, "Then prepare him a room and two sets of clothes."

After the maid retired, Nicholas II said to Charles, "She is the head maid here, if you need anything, tell her."

Charles nodded.

This corridor is not long, and at the end is a door decorated with gold.

When Nicholas II brought Charles to the gate, the two guards on both sides of the gate pushed open the gate.

Behind the door is a magnificent hall with an area of ​​thousands of square meters. The floor of the main hall is paved with dark smooth marble, and in addition to various patterns, there seems to be a map in the center. The surrounding walls and ceilings are dominated by bright red, decorated with golden patterns, and the window frames of the huge glass windows on both sides are also made of gold. Directly opposite the gate is a high platform about one meter high, on which is a rough stone chair carved out of rock without any decoration, with the coat of arms of a double-headed eagle carved on the back of the chair. On the wall behind the stone chair is a huge double-headed eagle coat of arms made of gold.

"This is Catherine's Basilica," Nicholas II introduced to Charles, "the place where the ceremonies are held in the Winter Palace. Every year between the autumnal equinox and the next spring equinox, we move from the other side of the river. Live here."

Then he pointed to the stone bench in the magnificent palace, which was rougher than the stone bench in the park and introduced: "Before our Rurik Empire was established, our ancestors sat on a stone on the top of the mountain on the other side of the river and managed this land. The land. When Fyodor became the first Rurik king, he made that stone into what is now the seat of the double-headed eagle. It has been the seat of every emperor ever since. I moved here When he was staying, it also followed."

After approaching, Charles carefully looked at this rough "dragon chair".

"Would you like to sit up and try?" Nicholas II asked Charles with a smile.

Charles shook his head desperately. This is a real guy, not a copycat dragon chair in the scenic spot. Each person takes 50 yuan for a photo session.

There are doors leading to the rear in two sections of the hall. Nicholas II took Charles into one of them. The backs of both doors lead to a corridor.

"The place where we were just now was the working area." Nicholas II continued to act as a tour guide for Charles. "After passing through this corridor, it is the living area of ​​the Hermitage."

Finally, Charles was led by Nicholas II into a spacious office. The walls on both sides of the office are filled with bookshelves. There are four sofas in a circle near the door. There is a coffee table in the middle of the sofa, and the innermost is a desk, and a pair of sofas are hung on the wall behind. Maps, there are a lot of labels on the map that say records.

Nicholas II asked Charles to rest on the sofa first. After reading the books on the shelf, he sat behind the desk by himself.

At this time, the headmaid came in pushing the cart. When the headmaid gave him a drink, he saw that Nicholas II's dinner in the cart was a schnitzel, a bowl of vegetable soup, and a few slices of white bread.

The books on the bookshelf in the office are all about philosophy and technology, and almost every book has a note from Nicholas II.

In a book titled "Slime Feeding Techniques" by a dragon named Veldora, on the page introducing the types of slime feeds, Nicholas II wrote on a sticky note: " Consider whether it can be applied in sewage treatment."

Charles smiled slightly, then beckoned to the head maid who was serving Nicholas II's meal—in fact, waiting for him to finish eating and collecting dishes—and asked her to bring a pen and paper for him.

Then Charles wrote and drew on the paper.

When Nicholas II finished dinner, he came to Charles' side, curiously watching what this nephew was writing.

The sewage in this world is basically domestic sewage, and the population density is low. Generally speaking, it is directly discharged into the natural water body, and there is no need for sewage treatment.

However, in densely populated places like Avalon City, Forged Holy Land, and Corn City, a large amount of domestic sewage will still cause small-scale environmental pollution.

And Charles and his family's pharmaceutical workshop was even more polluted. It is said that a long time ago because of this incident, he almost got into a fight with the neighbors in the lower reaches of the small river that passed through the territory. Therefore, their home lights up the technology tree of sewage treatment.

After Charles drew a flowchart of the slime sewage treatment process, Nicholas II asked him to explain~www.novelmt.com~ So Charles pointed to "?" and "?" and explained to Nicholas II : "These are coarse and fine grates to filter out large debris in sewage."

(￣?￣)??: "This is the primary sedimentation tank, which allows the sediment in the sewage to settle down."

(￣?￣)??: "This is the aeration tank, where the slimes live, they will eat the dirt in the sewage. Because the slime in the water is too dense, it needs to be installed at the bottom of the pool A device for supplemental air."

This kind of device that produces a string of air bubbles to oxygenate the water like in a goldfish tank is the most important thing in this sewage treatment system. people for many years. In the end, they solved the problem by driving the bellows with a water truck and using a bamboo tube sealed with slime glue as a ventilation pipe.

(￣?￣)??: "This is a secondary sedimentation tank, where the sludge can be settled, and then the clean water above is drained away, and the sludge at the bottom is a good fertilizer."

After listening to Charles' explanation, Nicholas II asked some data questions, but Charles didn't know the situation of the aquatic slimes here, so he could only let Nicholas II organize professionals to experiment slowly. .

In the end, Nicholas II took the blueprint and said that he would let experts conduct evaluation and experiments as soon as possible, and if possible, start construction as soon as possible.

Charles didn't know, but later Nicholas II named the first sewage treatment plant in Abyss City "Royal Charles Sewage Treatment Plant No. 1" in order to commemorate the contribution made by Charles, and almost laughed Diana who got the news to death. .

Later, this "Charles sewage treatment process" began to be popularized. In the field of sewage treatment, Charles' name has been passed down with sewage.
