Regardless of the type of RPG, duels are one of the systems that will be considered.

Although there are many games that do not allow "PK", duels that are carried out by mutual consent are a characteristic of many RPGs.

After all, fighting monsters all the time is just as boring, and it would be a lot of fun if players could compete with each other and compare their game skills.

Therefore, even in a world like SAO, there is a dueling system.

Outside the circle, if the players PK so unauthoritatively, the player who attacks first will be given the attributes of the offender, and the color buoy will turn orange and cannot enter the circle.

In the circle, players are not allowed to commit any crimes, and it is a safe area.

However, if it is a duel, then it can be fought both inside and outside the circle.

In such a situation, as long as both parties agree, the attacker will not become orange.

During the Closed Beta period, duels were often used to test their sword skills, hold events, or settle disputes.

However, since SAO officially opened and became a game of death, duels have become a forbidden act.

The reason, of course, is that if the HP goes to zero, it will usher in real death.

As a result, no player will engage in a duel without permission, and only those with ill intentions will want to use the duel system to commit murder.

Although players who know that their HP will die when they reach zero will not easily agree to a duel, SAO's duel is also designed into three modes.

The first is a mode in which you fight until your HP reaches zero———— "Perfect Win Mode".

The second is a mode in which the battle ends when half of the HP remains———— "Half-Loss Mode".

The third mode is the mode that ends when you hit the opponent with a powerful attack first———— "First Strike Win Mode".

During the closed beta period, almost no players were willing to choose the first-hit win-loss mode that was too simple to distinguish the winner and the half-loss mode that would make people feel unentertained to duel, but after the official operation, the full win-loss mode has become a real taboo, and no player will choose to use this mode for duels.

Therefore, even if there is a dispute that cannot be resolved, players will only choose to duel in half-loss mode or first-strike mode to duel.

But in the remaining two modes, it is also not completely free of the risk of death.

For example, in the half-loss mode of the duel, the duel will end when one of the two sides of the duel has less than 50% HP, in the circle, when the window indicating the duel result appears, the player's continued attack will be blocked by the system's protection and nullified, and outside the circle, the damage value will continue to be added, but this constitutes a criminal act and will become an orange player.

This may sound like a safe bet, but if a player has 1000 HP and is attacked enough to deal 600 damage with 510 remaining, the HP will immediately drop to 0.

Even in a duel, once the HP becomes 0, the player will still die.

On the other hand, the attacker, since it is an attack in duel mode, even if the player is killed, it will not become orange.

This mode has been used by orange players and even orange guilds, which has killed many players, and it once made people panic.

To sum up, the half-loss win-loss mode has also been listed as a taboo, and no player will choose blindly anymore.

This leaves only the last mode.

"Winning and losing mode in the first hit."

In one of the deserted squares on the 24th floor of the main block, Heathcliff, who was wearing a bright red robe with a cross shield in hand, looked at Rogen opposite, and a magnetic voice sounded.

"When one side has half of their HP left, or if they give a powerful attack, they will be able to decide the winner, right?"

Hearing Heathcliff's words, Luo Zhen, who was standing opposite him, teased the colorful butterflies and flower butterflies flying beside him, and before he could answer, Asuna, who was present in the name of watching the battle, took the lead in speaking out.

"But, Commander, the first-strike win-lose mode is also risky, right?"

As Asuna said, even if it's a first-strike win-loss mode, it's still risky.

For example, if both dueling sides do not use an attack that is considered "powerful" to weaken each other's HP until the opponent's HP is only a trace away from half, and then launch a powerful attack that is enough to take away all of their remaining HP, it will also create the same risk of death as in the half-loss winning mode.

It's just that......

"Then both sides have to have the idea of killing each other, deliberately control themselves, and don't use a strong attack to do it, only one person has the idea of killing the other party, then not only do you have to control yourself, but you also have to have enough skills to see through and avoid the opponent's strong attack, that is very difficult, right?"

Heathcliff said with an unchanged expression.

"Therefore, it is very difficult to complete the killing act in the first strike win mode, and this is already the safest method, if it can't be done, you can only refuse the duel."

With that, Heathcliff set his eyes on Rozhen.

That's kind of what it means, "Are you going to do this?"

Luo Zhen did not answer.

"Let's get started."

With such a sentence, Luo Zhen told everyone his choice.

“…………”

Asuna stopped talking, just stared at the room, not knowing what she was thinking.

Heathcliff, on the other hand, smiled suddenly, looked at Luo Zhen, and also looked at the two rainbow butterflies flying beside him, and his fingers summoned the main menu with smooth movements, and then manipulated it.

In the next second, a window appeared in front of Luo Zhen.

"The player - "Heathcliff" - asked you for a 1vs1 duel, did you accept it?"

Looking at this window, Luo Zhen did not hesitate to click the "YES" button, and chose the last of the three options that popped up, "Complete Win and Lose Mode", "Half Loss Win and Lose Mode", and "First Hit Win and Lose Mode" ———— "First Hit Win and Lose Mode".

"Ding!"

A large window immediately appears between Rogen and Heathcliff, and a 60-second countdown pops up.

In this moment......

"Choke!"

With a crisp sound, Luo Zhen pulled out the one-handed sword he was wearing at his waist.

"Huh..."

On the other hand, Heatscliff slowly drew his weapon from the cross shield he had equipped.

It was a sword that was even more slender than Luo Zhen had imagined.

It's just that it shouldn't be a thin sword, but a one-handed sword like Luo Zhen.

"One-handed sword and cross-shield?"

Luo Zhen lowered his body.

Although it seemed to be a very regular one-handed sword envoy, Luo Zhen faintly felt that it didn't seem to be that simple.

"Goo!"

"Whew!"

Caidie and Huadie seemed to be able to sense the solemnity of Luo Zhen's heart, and while making a call, they also entered the combat state.

Looking at the two men facing each other, Asuna was still silent, but she didn't know when she held the hilt of the thin sword at her waist, and she was still exerting force.

And just like that, the countdown went on all the time.

10…

“————「DUEL」————”

When such a window replaced the countdown and appeared between Rogen and Heathcliff, the two of them stepped on the ground at the same time and rushed out.

The duel between the two guild leaders officially began.
