Zhou Yuan soon came to the place where he had a hunch.

"This is ......"

The hunch is here, very strong. A stone had been cut off, and there were corners next to it that proved there was once a high-grade crystal - but it looked like someone had taken it away with a pickaxe.

"No, what I'm looking for isn't here......"

Zhou Yuan frowned and knocked on the stone, then took out the pickaxe and continued to dig. At this time, the things that were dug up were just some "stones with crystal corners" that were only worth a few gold coins, or just worthless "stones" - Zhou Yuan just took the pickaxe and cut all the stones one by one.

The black stream of data appeared where the stone had been cut open - which meant that something that made the program unstable appeared in the map in the form of matter.

So...... What the hell is that unstable thing? Zhou Yuan stretched out his hand and touched it towards the black data stream—it turned out that Zhou Yuan had an injured right hand, and after pulling it out, his right hand was gone, and as a result, Zhou Yuan was wasted a bottle of full recovery potion.

"Hmmm......"

Zhou Yuan thought for a moment, then took out a red legendary-quality prop like a bull's horn, hung a buff on himself, and then put his hand inside.

But it didn't work...... Even if Zhou Yuan opened the invincibility buff, this hand still disappeared in the turbulence of data, but because of the invincibility buff, the right hand was restored at the same time as it was withdrawn.

"What the hell is in there...... Helpers help me with a guard. ”

Zhou Yuan frowned - now it has actually reached the point where it is necessary to protect himself from the auxiliary program? Fortunately, the program of the black shadow is strong enough, this time the purple light curtain with the black shadow logo on Zhou Yuan's body has not been destroyed, and Zhou Yuan has successfully taken out that thing.

After Zhou Yuan's hand was lifted, the original position of the thing returned to its original state, and Zhou Yuan's hand was wrapped in a black data stream. Zhou Yuan gently groped for the style inside with his hand - it should be metal, and it seemed to be some kind of coin or something......

Zhou Yuan deposited the coin in his backpack. To Zhou Yuan's surprise, he actually saved it - but the other grids all turned into black data streams, and even the ingredients in Zhou Yuan's backpack, recovery potions and other things disappeared along with them.

"In other words, you can only save one coin......

Zhou Yuan clicked on the backpack interface and saw the style of the coin - that kind of coin was no different from the ordinary 100 yen coin, and he couldn't see the special features; the name of the item and the description were a mess of garbled characters, and he didn't know what it was used for.

Zhou Yuan took out the coin again, but there was nothing else in the backpack except gold coins - it seemed that it could really only hold one coin. It's just that through the auxiliary program Zhou Yuan, you can know that the gold coin only calculates the number, and the code position is different from the item.

In other words, the code represented by this coin can destroy all nearby material codes, but will not affect the game itself...... Is it?

"Wait......"

Zhou Yuan suddenly thought of something and turned the coin over.

I still remember that it was a science and technology exhibition at that time, and when Rentaro Okabe and Mayuri Shiina went to listen to Makise Hongriqi, they specially called Zhou Yuan...... And Zhou Yuan also went, but he didn't go to see Makise Hongliqi, so he didn't go in.

At that time, when they purchased the Upa capsule toy machine, Rentaro Okabe and Zhou Yuan used a single-sided coin for the first time in order to test the accuracy of the capsule toy machine's judgment of coins, and the result was a failure......

Zhou Yuan turned the coin over.

On the front side, there is a word "100 yen" written on both sides, and on the other side, there is a special "Okama" written by Rentaro Okabe as a sign......

That's right, this is the same thing that was used to buy the toy Upa in the first place...... Zhou Yuan remembered that his luck was not very good, so he only smoked a red one, and then went to the comic exhibition separately from Rentaro Okabe.

This coin is indeed ......

Suddenly, the coin disappeared from the backpack - rather abruptly, and even the effects were removed, and the contents of his backpack were gradually recovering.

Wait a minute......

Before Zhou Yuan could say it, he felt the touch on his body and his hand in the real world, and raised his hand to take a look.

A coin lies in the palm of his hand.

“…… This ......"

The hunch was correct, this thing was definitely peculiar enough. This coin Zhou Yuan took to do experiments, Okabe Rentaro took it to write, and was regarded by Zhou Yuan as the kind of coin that can be tossed with heads and tails, and the effect is not bad, there is Okabe Rentaro's handwriting on one side, and finally Zhou Yuan put it in the collection bag, and then disappeared after the world line change with the collection bag.

I didn't expect it to appear here, and there was no trace of wear and tear in a year and a half, and even magically crossed the game, came to reality, and was picked up by Zhou Yuan.

"Cut, is that guy actually ahead......"

At this time, a player with the appearance of the Karamburi Blade was hiding behind a rock, looking at it coldly.

There is no support for the Komaliu Blade, and he knows that he can't win Zhou Yuan in the game. And that coin appeared in the Sword Art Online game world, and it was useless to find Zhou Yuan in reality.

This coin is also one of the four items that the Eighth World needs to find, and it is indeed the one used by Zhou Yuan and Rentaro Okabe in the first place - its significance is not yet known.

At this time, it was taken by Zhou Yuan first and even extracted to the real world, but the Flowing Blade glanced at it and left, and it was this turn that made the Flowing Blade not see the moment when Zhou Yuan extracted the coin to the real world.

On the other hand, Zhou Yuan, who got the special coin, was in a much better mood, and went back to continue to guide Kirito and Asuna - now Kirito and Asuna can launch dozens of points of damage, that is, the basic power skills have been mastered.

The next step is to repeat the exercises hundreds, if not thousands, and get familiar with how to get the most out of it. However, Asuna obviously can't practice anymore - the second knife flow is mainly agility, and Asuna feels that she doesn't need such a skill anymore, and it is better to level up faster.

In fact, that's it, it's just a useless little trick, and the damage is definitely not as good as the Starburst Air Flow Slash. Kirito is still learning, and Zhou Yuan continues to teach Kirito some ways to use it.

And Kirito learned very carefully - after two days, Zhou Yuan had already begun to teach Kirito to rely on Tieshan.
