Time is like water.

Decades ago.

The captains and vice-captains of the Yalu City Guard, Willy and Mia, are in the prime of their lives. Because of his strong martial arts, one loves to wear black clothes and the other loves to wear white clothes, and he is vividly praised by everyone as "black and white double wall".

In the past years, no matter what happened, as long as the two people with black and white walls made a move, they would definitely turn the danger into a disaster.

The perennial companionship made the two people feel affection for each other, and eventually became husband and wife and had a pair of children.

Generally speaking, a single fifth-order martial artist is enough to be called a giant to deter the Eight Desolations.

And the only Yalu City has two fifth-order martial artists, Wei Li and Mia, to guard it, such a lineup can only be described as terrifying.

True to their title, the Black and White Walls are the solid walls that stand on the city of Yalu, the most powerful guardians. No matter what kind of battle, they can win.

It's just that......

Fifteen years ago, that battle to the death with the West French bandits.

In order to put an end to the atrocities of the Sifa bandits, the guards of Yalu City were locked in a bitter battle.

Facing the black and white walls, the masked man of the Western Law Thieves is a sixth-order martial artist!

Winning by numbers usually only happens between low-level martial artists. At the intermediate level, ordinary fourth-order martial artists can also engage in crowd tactics, and they don't eat this set anymore, let alone sixth-order martial artists.

In front of the two fifth-order martial artists, they could only be crushed.

"Ahem......"

After another confrontation with the masked man, both Willy and Mia were thrown from the far side, coughing up blood in their throats and suffering serious internal injuries.

With the abilities of the two of them, with the fifth order against the sixth order, how easy is it to win this battle?

In fact, the two of them also know that their chance of winning, probably, is not even one in 10,000.

"Also...... Can you fight?" asked Willy.

"Reluctantly, reluctantly......" Mia said.

Carrying everyone's hope, the two men stood up again.

No matter how many times they fall, as long as there is still a breath left, they will definitely get up again. That fighting posture, no matter how shaky, is also the spine that will not collapse in the hearts of the residents of Yalu City.

Looking at the masked man from afar, Willy and Mia's faces were more solemn than ever.

If nothing else, they will die in this battle today.

In fact, if these two people want to leave and save their lives, it is not difficult. But if they retreat, the other guards behind them, the people behind them, will be exposed to the enemy.

So, they have to stand here.

Even if you die, you don't back down half a step.

Guarding the city and its inhabitants is their duty above all else.

However, it was not enough to contain the masked man, Willy and Mia would at least have to suppress the man, or even defeat him, in order to win the battle......

This is simply wishful thinking.

If they can do such a thing, it can only be described as a miracle.

Miracles are always vividly depicted in the story, beautiful and full of fantasy. In real reality, it is almost invisible. A miracle is called a miracle precisely because it is something that is impossible to do in itself.

"Die. ”

The masked man's murderous angry voice fell, and everyone watched in despair as the black and white walls they had hoped for fell like autumn leaves.

Even at the cost of his life, the black and white walls are nothing more than a situation where a masked man is seriously injured.

Of course, this is already quite remarkable! An ordinary fifth-order martial artist, even if the two of them join forces, it is difficult to shake a sixth-order martial artist, let alone seriously injured.

"Mommy!"

In a far corner away from the battlefield, two children with somewhat similar faces witnessed this, and the cries of their loved ones were heart-rending until they were hoarse.

It was the darkest and most unforgettable day of their lives...... The masked man who killed their parents, half of the cold face exposed, the two children will never forget until death.

Coincidentally, Willy and Mia's lifeless eyes happened to look in the direction of the children.

In today's death, Willy and Mia will never regret it, nor will they be afraid to pay with their lives.

They can die calmly, but they feel guilty, and parents cannot accompany their children until they reach adulthood......

Time turns.

The fierce battle in Yalu City finally ended.

It was an unhealable scar in many people's hearts, the black and white walls fought for their lives to seriously injure the opponent's sixth-order martial artist, and the other guards were also red-eyed because of this, fighting to the death without their lives, and finally made the person who robbed the group have the idea of retreating.

At the same time, in that battle, the Western Law Bandit Troupe, which killed two fifth-order martial artists, became famous and became the most notorious gang in the empire, growing day by day. It was only after that Isaiah joined the Sipha Bandits.

And the guards who died in the battle will not come back.

They are all heroes admired by the people of Yalu City.

The black and white double wall is no longer there......

Sometimes, people always feel that those two people in the dark are not far away. They felt that Willy and Mia were still somewhere in the city, guarding the city of Yalu and the people, but they couldn't see it.

The current captain of the guard of Yalu City is a one-armed man named Mori.

Most of the guards of Yalu City were killed and wounded in the previous death, and he was one of the lucky ones who survived. Maury is the biggest fan of the black and white wall, and now he is also the man who takes over the burden of Willimia and carries it on his shoulders.

"Don't worry, Yalu City, I will definitely protect it! Don't worry about the two children, they will grow up well!"

He swore to the graves of the two men.

Even if he only has one arm left, let him use this arm to protect the future of the city and the growth of those two children.

With redoubled cultivation and perseverance, Mo Li finally broke through the shackles of the third-order peak and stepped into the dignified fourth-order realm.

The Yalu City Guardian gradually redeveloped into a scale.

The streets and alleys that were reduced to ruins in the battle to the death have also been restored to their former prosperity.

All of this was defended by the guards who died alive and dead, with their blood and lives.

Time is like flowing water, year after year, and finally the pain in people's hearts has been diluted. Only after tea and dinner, sometimes they talk about the war of that year, the heroes of that year, thrilling, singing and crying.

The powerful, reassuring figure is bright black and white, no language, resolute as a mountain, and has only stayed in people's memories since then.

Life and death, there will be no goodbye.

Willy and Mia, the black and white walls of Yalu City, seem to have become history since then.

Until—

Ten years later, a pair of teenagers and girls dressed in black and white clothes inherited the name of black and white walls and walked into everyone's sight......
