The Troublesome Hero Among the Heroes

Under the afterglow of the sunset, Nicholas II left Jesse Mack’s farm with Charles “biu”, and then appeared on a wall surrounded by soft green, white In the garden surrounded by pillars and green roofed buildings.

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

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

When Charles left the garden with Nicholas II, a young guard asked the person next to him in a low voice, "Captain, shouldn't that kid be Your Majesty's..."

"Don't talk too much, can you talk nonsense about Your Majesty's family affairs?" His Captain stopped him from speaking, "Just know some things by yourself."

Gula II took Charles into the building with the garden all around, and Charles discovered that it was a palace that looked splendorous and majestic.

There are crystal lamps on both sides of the corridor. Paintings protected by golden frames are hung on the white walls, and there are exquisite patterns painted by gold paint on the white ceilings.

A silver-haired, red-faced human maid in a maid costume has long been waiting there. She bowed and saluted when Nicholas II came, "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 to point. Charles said: "Then prepare him a room and two sets of clothes."

After the maid retired, Nicholas II said to Charles, "She is the maid here, if you have any needs Just tell her."

Charles nodded.

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

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

Behind the door is a magnificent great hall with an area of ​​thousands of square meters. The floor of the great hall is made of dark smooth marble. Apart from various patterns, there seems to be a map in the center. The walls and ceiling of all around are made of bright red as the main color, decorated with golden patterns, and the huge glass windows on both sides of the window frames are also made of gold. Opposite the gate is a high platform about one meter high. On it is a rough stone chair carved from rock without any decoration. The back of the chair is carved with the coat of arms of a double-headed eagle. On the wall behind the stone chair is a huge double-headed eagle coat of arms made of gold.

"This is the Ekaterina great hall," Nicholas II introduced to Charles, "It is the place where the Ceremony is held in the Winter Palace. Every year between the autumnal equinox and the second year's vernal equinox, we will go from the river The other side moved here to live."

Then he pointed to the stone bench in the magnificent palace, which was rougher than the stone bench in the park, introduced: "Before the establishment of the Rurik Empire, our ancestors We sat on a rock on the top of the mountain on the other side of the river and managed the land. When Fyodor became the first King Rurik, he built that rock into the seat of the double-headed eagle. From now on, it will be the throne of every emperor. When I moved here, it followed."

As he approached, Charles carefully looked at this rough "Dragon Throne".

"Do you want to sit and try?" Nicholas II asked Charles with a smile.

Charles shook his head desperately. This is a real guy, not the copycat Dragon Throne in the scenic spot. Each person takes 50 yuan to take a photo.

The two sections of the great hall have doors leading to the rear. Nicholas II leads Charles into one of them, and both doors lead to a corridor behind them.

"The place where we were just now was the work area." Nicholas II continued to be a tour guide for Charles, "After crossing this corridor, it is the living area of ​​the Winter Palace."

In the end, Charles was led by Nicholas II into a spacious office. The walls on both sides of the office are filled with bookshelves. Near the doorway, there are four sofas forming a circle. There is a coffee table in the middle of the sofa, and the innermost is a desk, and a pair is hung on the wall behind. Map, there are many labels on the map with records written on it.

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

At this time, the head maid came in with the cart. When the head maid gave him a drink, he saw that Nicholas II’s dinner in the cart was a fried steak, a bowl of vegetable soup and A few slices of white bread.

The books on the bookshelf in the office are of philosophy and technology. Almost every book has notes written by Nicholas II.

In a book called "slime feeding technology" by a giant dragon named Verdra, on the page that introduces the types of slime feeding, Nicholas II puts it on the sticky note It says "Consider whether it can be used in sewage treatment."

Charles slightly smiled, and then he beckoned to the head maid who was waiting for Nicholas II to dine—actually waiting for him to finish collecting the dishes—and asked her to get paper and pen for herself come over.

Then Charles wrote and drew on the paper.

When Nicholas II finished his dinner, he came to Charles's side and looked curiously at what the nephew was writing.

Sewage in this world is basically domestic sewage. In addition to the low population density, generally speaking, it can be discharged directly into natural water bodies, and there is no need for sewage treatment.

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

The pollution in Charles's pharmaceutical workshop is more serious. It is said that a long time ago, because of this, he almost had a fight with his neighbors in the lower reaches of the river that passed through the territory. Therefore, their home lights up the technology tree of sewage treatment.

▦→▩→⍌→⌨→⊍→≋

After Charles drew a set of slime sewage treatment process flow chart, Nicholas II asked him to explain.

So Charles pointed to "▦" and "▩" to explain to Nicholas II: "This is a coarse grille and a thin grille, used to filter large debris in the sewage."

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

(￣ᐦ￣)☞⌨: "This It is an aeration tank, where slime lives. They will eat the dirt in the sewage. Because the density of slime in the water is too high, it is necessary to install a supplementary air device at the bottom of the tank."

This A device like a goldfish bowl that emits a string of bubbles to oxygenate the water is the most important thing in this sewage treatment system. The problem of excessive density of aquatic slime leading to hypoxia death has plagued Charles's ancestors for many years. . In the end, they solved the problem by using a water tanker to drive the wind box and apply a bamboo tube sealed with slime glue as a ventilation pipe.

(￣ᐦ￣)☞⊍: "This is a secondary settling tank, where the sludge can be settled down, and then the clear water above is drained away. The sludge underneath is a good fertilizer."

After listening to Charles’ explanation, King Nicholas II asked some questions about the data. It’s just that Charles didn’t know the situation of the aquatic slime here, so the professionals of the Nicholas II organization could only slow down. Experiment slowly.

In the end, Nicholas II took the blueprint and said that he would let the experts evaluate and experiment as soon as possible, and if possible, put it into construction as soon as possible.

Charles didn’t know. Later, to commemorate Charles’s contribution, King Nicholas II named the first sewage treatment plant in Abyss City as "Imperial Family Charles First Sewage Treatment Plant." Diana laughed to death when he got the news.

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