Chapter 676: Sword World Star Upgrade! (Main World)

Sword Art Online world, 2031.

"It's been nine years without me noticing."

"Yes, if things had gone on as normal, even Suguha would have graduated from college a while ago."

To Kirito's adoptive parents, Suguha's parents, Kiritani Minetaka and Kiritani Midori, who were sitting at the dining table, sighed with emotion, because today was the ninth anniversary of the appearance of the mysterious tower.

There were too many changes in nine years, and they could be said to have missed their children's entire youth. Although they occasionally got news about the two children because of Kirito's efforts, they still felt a little dazed every time they thought about the fact that the children were fourteen or fifteen years old when they landed, and they would be twenty-three or twenty-four years old when they saw them again. They didn't know what it would be like.

"According to the agreement between the country and the alien, Kirito and Suguha will be back in four or five months... There won't be any accidents, right?" Kiritani Midori said with some worry.

"We have to trust the country." Kiritani Minetaka shook his head: "There shouldn't be any mistakes."

"That's good... Speaking of which, dear, do you think I should prepare a gift for Yuuki Asuna?"

"You think too far ahead, let's eat."

"How far is it..." Kiritani Midori muttered.

After enjoying a sumptuous dinner, the two put down their chopsticks one after another. Kiritani Minetaka went to watch TV, and Kiritani Midori called to the kitchen: "Xiao Qian, I'll trouble you with these dishes and chopsticks."

"Okay, ma'am." The answer was a crisp girl's voice, and a robot full of metallic beauty came over.

It skillfully arranged the leftovers, cleaned up the garbage on the table, and then went to the sink to wash the dishes. The movements were flawless and clean and fast.

In the past nine years, especially in the past three years or so, the world has changed very quickly.

In the long run, space immigration is already something that can be achieved, and human bases are being built on Mars and the moon in full swing.

To put it more recently, the car that my family just replaced uses the latest electric technology. A small "calcium carbide" is enough to last for more than 18,000 kilometers, and the cost of electricity is very low. Oil cars have basically been swept into the corner.

The birth of various industrial robots and civilian robots has liberated manpower. Although it had an impact on society at first, it has gradually eased with the rise of new industries.

Medical care, communications, travel...

There are new changes every day.

Nowadays, everyone has developed the habit of watching news and reading consultations at all times, because you don’t know if you will not be able to keep up with the changes in the world’s trends if you don’t go out for three days.

Kiritani Minetaka was watching the evening news.

And at the first moment, he found that the host’s expression was a little dazed, and his hands holding the manuscript were shaking slightly-that was due to extreme excitement, and he couldn’t control his unstable emotions no matter how hard he tried.

Something big happened?

"I, my station's news. According to the longevity treasure 'Nitolomi' in the mysterious tower and the immortal disease 'NDH', with the help of our friend Mr. Ji Xing from another world, our national treasure scientist Professor Suiren has made a major breakthrough in his research, and the life potion 'LLΙ type' has entered the clinical stage.

Preliminary estimates show that this drug can cause the human body to produce... delay... reduce... and eventually reach the level of increasing the average human lifespan to 100 years. Please continue to pay attention to the follow-up progress!"

"Actually..." Kiritani Fengtaka was shocked and looked at his wife who was also shocked.

Can we expect the arrival of an era of immortality? !

The world was shocked by this!

...

Starlight (six stars): 0%

At the same time, in the mysterious tower, Ji Xing looked at his wrist, and the first five seven-star beads emitted a perfect light, and the fifth star that required 100 billion starlight was finally full!

And soon after, a new seven-star bead prompt popped up and appeared in front of Ji Xing.

[Under your influence, the one-star world 'Sword Art Online' is promoted to two-star, and special rewards are obtained, and a special function: virtual reality is enabled. ]

[Virtual reality: In the invaded world, you can consume a certain amount of starlight to experience the impact of one or several choices in the virtual world, and deduce the subsequent events. (Each invaded world can only be used once)]

Sounds like... a life simulator?

It is a very practical function.

Just like in the mysterious tower, if Ji Xing uses this function after entering, he can understand in the virtual deduction whether it is better to 'directly explain the identity to the players and unify the players to attack the mysterious tower', or to conceal the development and gain trust first.

The former can also know which players are dragging their feet and what hidden dangers there are in the simulation, which is equivalent to an extra opportunity to eliminate wrong options.

I don't know how much it consumes, and it's a pity that it can't be used in the main world, but this function will definitely play a role in the next invasion and bring more benefits to Ji Xing.

"Great profit. Although the virtual reality technology in Sword Art Online is very exaggerated, and can even create artificial worlds and souls, it is only a one-star world, probably the top of one star.

We have to wait for the Hunter World. Holy Light is not easy to learn. Three years have passed, and Jin and Biscuit are still one step away from the initial awakening. Xiao Gon and Killua still need at least two or three steps... There is at most half a year, so it should be in time."

As for whether one or two people can master the Holy Light and pass it on to the Hunter World from four stars to five stars, it is a matter of luck. Ji Xing also shared those technological things with the Hunter World, but it is obviously much more difficult to upgrade from four to five stars than from one to two.

After browsing the 118 full-level skills in the attribute column, Ji Xing thought for a while and set off to the first floor of the mysterious tower.

Black Iron Palace, square.

It is the "birthplace" of the new player.

Ji Xing stood in the middle of the square and took out 1,500 magic-sealing silks from the prop column, almost covering the ground here!

"If you are conscious, you should have more power after the level has just been upgraded. Can you hear me?"

He spoke to the void, and the person he was communicating with was the world of Sword Art Online!

"If you are conscious, if you have been watching here, you should be able to determine my identity as an intruder. I have no ill will towards you, I just take some things I need."

"We are not enemies. Under the current circumstances, we are mutually beneficial, and you have already gained sufficient benefits. When I defeat the Boss of the 100th floor, you will still benefit."

"So..." Ji Xing grinned: "Why don't you show it a little? You should know the benefits I want, and it shouldn't be difficult for you, right?"

Silence.

After the voice fell, Ji Xing stood there for a minute without feeling embarrassed.

It's better to try it out.

Although he has invaded so many worlds, this is the first time he communicates with the world he invaded... even if he is not sure whether he can be heard.

Sword Art Online world, you don't want to be invaded by Yu Yu Hakusho world, right?

So you won't try to kick me out.

It's best if there is benefit, but it's not a loss if there is no benefit.

After waiting for a while, there was no reply, Ji Xing shook his head and bent down to collect the "Demon Sealing Silk", but suddenly saw that this item had a new function.

[Synthesize]

He couldn't help but smile.

"Synthesis, confirmed!"

Buzz——

The bright golden light filled the entire Black Iron Palace Square, and 1,500 Demon Sealing Silks quickly merged together and turned into a dark red...key.

[World Key]

[Level: Unknown]

[Effect: Unknown]

[Introduction: An ordinary key, which seems to contain a trace of the origin of the world. ]

"Happy cooperation." Ji Xing looked up at the sky.

...

Demon Continent.

Ji Xing's main body also looked up at the sky.

The setting sun was setting in the west, and the red clouds were like blood, dyeing half of the sky, which was magnificent.

It was July 1, 2105 in the demon calendar, and there was only half a year left before the three hundred years!

"Does this world have a world will? Is the world invaded by the Seven Stars Pearl real or virtual? The three worlds of Sword, Hunter, and Youyou are close, is there a world that is closely connected to this world? Are the supervisors of the demon clan stationed in the adjacent world?"

Many thoughts flashed in Ji Xing's mind. In the past three years, the changes in the demon continent have also been huge.

DNA demon detection technology has now been implemented in all towns above level five, ensuring the cleanliness of the hunter team. Although there is no condition to do universal detection, random inspections have also been fruitful from time to time, greatly reducing the situation of infiltrating demons eating and drinking.

As the three hundred years approached, the friction between humans and demons has become more and more, and small wars broke out every day. Many remote villages and towns have cancelled their establishments, and a large number of people have migrated to larger towns.

As the center of the human race, Zhongdu has a population of nearly eight million, and the streets are even more prosperous, just like the splendor before the disaster.

Ji Xing has not made any great inventions, but the name Li He has long been known to everyone. Even adults will use his name as an example to motivate their children.

The national idol has brought a huge amount of starlight.

[Starlight (six stars): 1387.542 billion/10 trillion]

But there is still an insurmountable gap from the 300 billion of five and a half stars. Just as Ji Xing judged, this world does not have the population and strength to allow him to collect starlight to five and a half stars.

The conversion rate of half-people has been steadily increased to 70% step by step. The speed of self-cultivation is getting slower and slower. If he had not accumulated terrifying talents in one world after another, every 1% increase would probably take 10 years.

For Ji Xing, now he has more than 90% confidence in "successful self-rescue"!

But if you want to save the world...

"Li He." At this time, Xiao Ai walked into his office and said, "Sun Qin just called and said that Zhongdu is going to hold a 'Human Technology Seminar' in three months. It will gather elite professors from all walks of life in the five cities. I want to ask if you are willing to host this conference as the host."

"Before thinking about victory, think about defeat first. Even if you lose the war in half a year, you still have to leave seeds and the future, right?" Ji Xing shook his head and said, "It's about to start."

Xiao Ai nodded: "Yes, it's about to start."

3k, there is another chapter before 12 o'clock, and then there will be a long main world plot.
