Known 1: The river bank is 20 meters above the water surface;

Known 2: The deck of the ship is 25 meters above the water;

It is known that the boat is traveling at a speed of 150 meters from the river bank at a speed of meters per second;

Q: If you want to throw Charles from the river bank to the boat, find Charles's muzzle velocity, projectile angle and advance without considering air resistance.

Artoria answered: Intuitively.

Charles reacted: "The people on the boat caught me!"

At this moment, Charles decided to learn the advanced wind magic that can make people fly. The last time I "overclocked" at the altar, the wind wing I used was good, and it was capable of flying short distances and dodging maneuvers in tight spaces, and with a little light and shadow effects, it was a terra.

As for Artoria, she was able to tread on the water, she jumped from the bank to the water, and trotted all the way to the boat.

Mordred approached Charles, who was holding a bottle of mint water, and sniffed, "You smell of mommy." ”

"Don't worry about the details. Charles pulled out a piece of candied fruit and stuffed it into Mordred's mouth.

The fleet was now chartered by caravanserans, and the ship they were now on was about thirty meters long and seven meters wide, and was a common cargo ship on inland waterways. This ship carried the main members of the caravan and the most valuable cargo, and other vehicles, horses, etc., were transported by other ships.

Because of the extra time spent in Mason City, the caravan will directly enter the river by boat in the following days, and then go down the river to the knowledge city at the mouth of the sea, where it will rest and change ships before taking the sea route south to the Elven Tree Sea to complete the caravan's journey this year.

While on the way, many of the caravan members would leave for the New Year and return home in February, or wait for the caravan to arrive at several places along the way.

In a hurry, the fleet did not make any stops when passing through Charles's grandfather's territory, and headed south into the river.

Sailing life on the mighty and endless rivers is very boring, especially with a fleet that doesn't need to make many stops along the way.

After the novelty wore off, Charles simply asked the boatman for a fishing rod and sat on the side of the boat with Halkara, learning Elven language while fishing.

Now Charles's elven language can barely reach the level of everyday conversation, and the most important thing is that he is not afraid of being scolded by elves in elven language now.

At this moment, there was a noise on the shore in the distance, and a group of dog-headed and human-shaped animals in tattered clothes could be seen in the reeds on the shore, brandishing weapons such as clubs and stones, shouting at the fleet.

Someone on the ship shot an arrow at them, and the arrow exploded above their heads, causing the kobolds to flee from the shore in fright.

"These kobolds are so annoying. Halkala pouted.

Charles nodded in agreement.

Unlike the orcs of Sister Meow Momiji and Amiya on Rurik's side, humanoid demons such as kobolds belong to demonic beasts with a certain amount of intelligence, although their intelligence is only equivalent to that of human children.

Unlike goblins, goblins are only mostly physically weak, but their IQ is not low, while humanoids are not high in body and IQ.

However, these humanoids, which often come in groups and use some simple tools and weapons, are still a bit difficult to deal with.

When these humanoid demons are so numerous that they have the illusion that "I can win", their will to fight will skyrocket. If you demoralize them, they will flee as fast as they can.

Charles's maple grove also occasionally appears in the maple grove of his family's domain, and some humanoid demons from afar often steal the bucket of maple syrup from the people who collect maple syrup. However, many maple syrup collecting teams will leave a small bucket of maple sugar filled with poison not far away and let them steal it during breaks.

Near noon, Elizabeth called Charles to the bow of the boat.

Seeing the solemn expression on Elizabeth's face, Charles felt that something was going to happen.

Elizabeth said to him, "Charles, would you like to live with the Elven Tree Sea for a while?"

Charles looked at Elizabeth suspiciously, unable to understand what was going on. At this time, he felt that a magical barrier had been cast around him, isolating the conversation between the two of them from the outside world.

Charles thought for a moment and replied, "I think it's okay." ”

Elizabeth nodded, "Alright, I will leave the caravan for a while after returning to the Elven Court this time, and you will follow me during this time." ”

Charles nodded in agreement.

Elizabeth continued: "Aunt Leif brought news from my mother that the fishmen on the south shore of the Tree Sea were about to attack the coastal area again, and my mother asked me to go back and lead the army to take charge of the defense of the coastal area. ”

"I've thought about it for the rest of my time, and I'll take over this task after I've healed you, and then you can follow me to the south. ”

"If you can, I'd like you to add some experience of war. ”

"No problem. Charles narrowed his eyes, his primary goal now was to improve his strength and slash his enemies, and there was no better place to improve his strength than on the battlefield.

"You have to be mentally prepared. Elizabeth continued, "The war between the elves and the fishmen of the south has been going on for thousands of years, the longest war on the continent, and there is no room for détente between the two sides. ”

"This is not a small fight in the previous period, but a life-and-death war that takes place on thousands of kilometers of coastline, and anyone will die in the war, including you and me. ”

"I'm fine. Charles was at peace at this time.

Seeing Charles's answer, Elizabeth nodded, and she finally said, "Don't talk about this matter to others, I will announce it to everyone when the time is right." ”

Charles continued to nod.

While the magic barrier had not yet been removed, Charles asked a question that had been bothering him for days, "Sister, do you know what it is when Philip dug a pit and let Artoria go down?"

Elizabeth replied with a smile, "When you go to Abyss City in the future, go to the east and south more, and you will see the 'Pendragon Canal' that she blasted out to irrigate large areas of farmland." ”

At this time, Charles had already guessed what was going on.

The ancestor first dug a pit in the ground, marked the direction, and then let Artoria go down.

Artoria uses the EX curry stick to make a big move towards a specific location, and a section of the canal is almost complete.

For Artoria, the "Knight King" at the time, such a thing was enough to make her vomit blood.

Then again, Charles decided that if it was his own, he would let Artoria do the same.
