This guarantee is actually made up by Yang Cong, because Yang Cong himself is not immortal, but he lives several times longer than others, and he will not age.

But Yang Cong believes that he has the system and sooner or later it can be realized.

"Oh? Eternal life? Very attractive look. "Heathcliff (Kayaba Akihiko) is also a little interested, he doesn't know if Yang Cong is lying or what he said is true, but this is enough to arouse his interest.

"How?" Yang Cong looked at Heathcliff (Kayaba Akihiko), and now it was time for Heatscliff (Kayaba Akihiko) to make a choice.

"I feel like immortality is good, but are you sure you can give me what I want?" Heathcliff (Akihiko Kayaba) looked at Yang Cong.

He thought about it when he was very young, and then he would make this world now, but this world will eventually be destroyed, and he is very curious about what Yang Cong said, he doesn't know what makes a person have such confidence.

"I can give you what you want, and I can give you room to develop." Yang Cong said.

"Okay, then I'll see what I can get." Heathcliff (Akihiko Kayaba) wanted to give it a try, and he didn't regret it anyway.

Life is all about learning to gamble, and if you bet right, then you have succeeded.

Hearing Kayaba's consent, Yang Cong directly asked the system to use the contract on Heathcliff (Kayaba Akihiko).

The contract is that as long as Yang Cong does not die, the person who signed the contract with him will not die.

And in the same way, if Yang Cong dies, then the person who signed the contract with him will die.

"Akihiko Kayaba, don't resist, go with your heart."

Heathcliff (Akihiko Kayaba) nodded, indicating that he heard it.

"Sign the contract..."

Kayaba Kiehiko suddenly felt a force guiding him.

He didn't know what it was, but he thought that this should be what Yang Cong said would follow him forever.

"If the contract is signed successfully, 300 points will be deducted (2400 points remaining)"

"Now that you know, I can give you what you want." Yang Cong spent a little more points to strengthen Kayaba Jinghiko's physical ability.

"Now the two of us have signed a contract, and you are bound by me to serve me." Yang Cong said.

"Hehe, can I regret it after all this, I hope you can do what you said and give me what I want." Heathcliff (Akihiko Kayaba) said.

Heathcliff (Akihiko Kayaba) also sensed the connection between himself and Yang Cong and believed what Yang Cong said.

And he is looking forward to what Yang Cong said to give him what he wants.

That's what Heatscliff (Akihiko Kayaba) cares about the most.

"I will." Yang Cong smiled and looked at Heathcliff (Kayaba Akihiko), at this time Heathcliff (Kayaba Akihiko) has been subdued by him, which means that his goal has been achieved.

"The mission was completed, and it was recognized by Akihiko Kayaba, and the task reward was the world's 'seed'."

Yang Cong, who received the information, looked at the information on the completion of the task, and knew that Akihiko Kayaba had sincerely chosen to follow him.

"So now, my master, what do you need me to do." At this time, Heathcliff (Akihiko Kayaba) looked at Yang Cong with interest, not knowing what choice Yang Cong would make now, whether to end the game directly or continue to play.

"The relationship between the two of us can only be known by the two of us, and I think the two of us should have a fight." Yang Cong said: "And I think this ultimate battle should be after the seventy-fifth floor." ”

Although Yang Cong has been recognized by Heathcliff (Akihiko Kayaba), Yang Cong still feels that it is best to fight him and then defeat him, otherwise Yang Cong will not have any sense of achievement.

Then Yang Cong still talked about Yui, he had already planned for Yui, and now he just reminded Heathcliff (Akihiko Kayaba)

"Also, I think you know Yui's identity better than me, now that she's my daughter, don't move, after SAO, I'll get a realistic body for her, so that she can be like a normal person."

"As you wish, my lord." Heathcliff (Akihiko Kayaba) spoke in a respectful tone.

This made Yang Cong a little uncomfortable, after all, he still didn't want others to call him master, so he said: "Don't call me master in the future, it's weird." ”

"What's that called?" Heathcliff (Akihiko Kayaba) looked at Yang Cong.

"Just call me Yang Cong." Yang Cong said.

"No, how can that work." Heathcliff shook his head and said, "Since I am already your follower, then there is a division between us and master. ”

"Then what do you call it?"

"How is the lord."

"Okay, okay, that's it."

…………………

After that, Yang Cong left the headquarters of the Blood Alliance Knights, and as soon as the headquarters of the Blood Alliance Knights was headed, he saw Yasi and Yui.

"Daddy!" Yui waved to Yang Cong with a low voice.

"Yui." Yang Cong also saw Asuna and the two, and trotted all the way to the front of the two.

"I shouldn't ask, but I want to ask." Asuna asked, "What did you talk to the head of the regiment?"

"Nothing, just talking about the future." Yang Cong didn't lie to Asuna, at least what Yang Cong said was true, talking about the future.

"Hmm." Asuna was afraid that something would happen to Yang Cong and the head of the regiment.

After all, Yang Cong and the head of the regiment are two very strong people.

After that, Asuna and Yang Cong took Yui to dinner, and the next day they were going to attack the boss.

Everything is in place.

In the evening, Yang Cong and the three returned to Asuna's house.

The next morning, Asuna and Yang Cong took Yui to Kirito and them.

Kirito is also one of the high-end players, and of course he was also drafted.

And the reason why Yang Cong and Asuna came was to talk about Yui and put it here.

After all, Yang Cong and Asuna are both going to attack the boss, of course, they can't bring Yui to go.

Yui is also very obedient, no noise, and obediently plays with Yuki.

So Yang Cong, Asuna and Kirito rushed to the meeting place.

As soon as I arrived at the meeting place, the whole venue was full of people, at least hundreds of people. This time can be said to be SAO's biggest strategy battle to date.

They are led by the Knights of the Blood Alliance, the first major guild, the Second Great Guild, the Ayn Grant Liberation Army, and the Third Great Guild, the Holy Dragon Alliance.

Gather the scale of nearly 300 people to attack the boss.

What they don't know is that this is not only the biggest strategy battle in the entire SAO, but also the last battle of the SAO.

After that, the whole game is over.

This once terrifying death game is over.

At that time, SAO will only be history.

Yang Cong and the three of them appeared to me, and they immediately attracted everyone's attention.

Asuna is the most famous of them, and there is basically no one present who does not know her.
