The protagonist chased the villain, and Tiandao screamed in anger

The sun penetrates the sea surface, and through the medium of the seawater, the swaying waves cast fish-scale-like light patterns. The seaweed in the shallow sea waters grows very well, soft like the fine hair of animals, and sways constantly with the water flow.

The silver-tailed mermaid led her fellows behind her, swinging her flexible and wide tail fin and swimming towards the deep sea. The rapidly broken water current scared the schools of yellow-bellied fish that were swimming in groups and made them flee in all directions.

[Wow, faster, so cool!] You Mu swam very fast. Tian Dao looked through You Mu's eyes and felt like he was on a yacht moving very fast. He jumped around excitedly.

After three years at Fred, I was so depressed that I found it strange to see any new scenery.

The deeper you go, the less penetrating sunlight is. In the dim light, within the deep blue seabed, a glowing underwater city can be vaguely seen.

As we got closer, a mermaid patrolling outside the city swam over with a lantern made of anglerfish light balls.

"Your Highness!" The man with the emerald green tail came over. He had received the news early in the morning and was waiting outside the capital. When he saw the silver-white figure approaching from afar, he excitedly greeted him.

"I haven't seen you for three years. You've grown up." You Mu looked at Xi's physique, which had doubled in size. He smiled and nodded with satisfaction.

[Is this Xi? I really can't tell. The little guy who looked like a bean sprout before has grown into a man! ] Xi has changed a lot. If it weren't for the bright hair color and fishtail, Tiandao really couldn't tell.

"I remember what His Highness said, that we must protect Tislanton and work hard to grow up and become stronger!" Xi held the bone knife and recalled solemnly what His Highness said while stroking his forehead when he left that day.

Xi is not very old, and has just reached adulthood. He has no relatives, and he is grateful to the White Tail royal family for their kindness.

"Well done. No matter what, we must protect our own waters." Xi is not a bad boy.

In the original plot, the reason why the stranger was brought back to the royal city without any precautions was because he had not received ideological education and security awareness reinforcement.

He was not aware of the dangers of bringing humans into the royal city without permission.

Argonas was still rational and did not bring any major disaster to the royal city. He was also discovered and detained by the guards in time. If Xi had brought a real spy who was extremely vicious and wanted to bring disaster to the royal city, the mermaid clan would be exposed to the enemy's sight.

In the story, You Mu saw Xi's advantages. He knew the terrain of the water, was flexible, had good eyesight and observation, and was stronger than the average mermaid. He was a good candidate for a scout.

Therefore, after entering the small world, You Mu, who made full use of everything, settled the trivial matters in the royal city and recruited some orphan fish similar to Xi before going to Fred.

"Yes" was encouraged by You Mu, and Xi's confidence increased.

"How is the Royal City now?"

"Everything is fine. The king is in much better spirits. The little mermaid at the Guidance Institute is growing very fast. They all miss Your Highness very much."

"Where's Yaji?" After a brief chat with Xi, the mermaids returned to the royal city together. You Mu didn't find a familiar figure in the patrol team, so he asked.

Yaji is the master that You Mu found for Xi. He is also the captain of the royal city patrol team, responsible for the stability inside and outside the royal city. In the past, Yaji should have been there at this time.

"Master has been temporarily transferred by the king to the trade line to supervise and stabilize the transportation of goods on the water and underwater. Your Highness, please walk slowly. I still have to continue leading the team on patrol, so I can only send you off here." Xi escorted You Mu to the city gate and stopped swinging his fish tail. Although he really wanted to follow Your Highness into the city, he could not leave his post without permission.

"Well, go ahead." He nodded in agreement. After briefly understanding the situation, You Mu led the mermaid behind him into the city.

The buildings of the royal city are made of slate rocks from the seabed, which were built and repaired bit by bit by the ancestors of the mermaids. Seaweed and colorful corals grow on them, and lights decorated with luminous pearls can be seen everywhere.

The mermaids swam with the help of their tails and did not need roads. It was only after they began to trade with the outside world that they opened up a wide road paved with gem beads leading to the central castle in order to welcome guests.

The number of mermaids is rare. One royal city and scattered settlements nearby account for most of the mermaids in the sea.

A white-tailed mermaid flashed by, and the familiar scent brought by the water waves made the mermaids living in the stone houses on both sides of the road look out of the windows one after another.

"It's Your Highness!"

"His Royal Highness is back!"

They returned all the way to the castle where the royal mermaids lived. The mermaid guards who followed them returned to their teams. Ryan followed Youmu to the palace of the Mermaid King to report the contents of the contract.

The main hall is large, covered with bright red carpet, and the light refracted and diffused by glowing jewels and crystals from the ceiling is soft and bright.

Sitting on the throne made of whale skeleton, the mermaid king's black tail is much longer than You Mu's tail. The thick ink-black tail is decorated with dazzling gold edges, which is the most direct symbol of royal identity.

"Father, I'm back"

You Mu swam forward a few steps and stopped beside the mermaid king.

“Just come back”

The broad webbed claws landed on You Mu's head. Although the mermaid king was old, he was still strong and powerful. He reached out and patted his son's head. After carefully checking that he was not injured, he felt relieved.

He originally wanted to let Fred go, as his youngest son's situation was special. The albino mermaid needed more patience to be cared for and was obviously not suitable to be exposed to humans.

It’s just that the eldest son doesn’t know how to socialize and is a taciturn person who only knows how to hide in the house. When he was confused and in trouble, the younger son stood up and convinced him with reason and evidence.

Now it seems that Mu is indeed more suitable than Luo to manage this royal city.

"Your Majesty, this is the conclusion of this peace negotiation. When leaving Fred College, Your Highness was ambushed by Enya, but we have no direct evidence..." Ryan presented a waterproof paper contract and mentioned the attack he encountered when leaving.

The mermaid king used the water to roll the contract over, lowered his eyes and flipped through it, and after listening to Ryan's words, he paused for a moment and said:

"Mu, go check on your brother. I don't know what Luo has been researching in his room these days. You are the only one who can talk to him. Rui En, follow me to the side hall."

"Yes, Father."

You Mu turned his tail and swam out.
