In the closed "cylinder", the teenager and the girl look at each other.

"How do you choose this? There's no button or anything like that......" Fang Chang looked around a little suspiciously.

"Stupid." Zhou Yan pursed his lips and stretched out his little white hand to click on the text of "Duo Mode" in the air.

Unsurprisingly, when her fingers "touched" the text in the air, the game's interface changed.

The title that floated in the air disappeared. In its place is a "game tutorial" that is also holographic mode.

"How is this done?" Fang Chang could hardly believe his eyes, it was the first time he had seen this game mode.

"Holographic interactive system." Zhou Yan said coldly.

-- The so-called holographic interactive system is a relatively advanced holographic projection, which is different from ordinary holographic projection in that this kind of projection is interactive. Users can even interact with the projection to create a "tall" look.

As for the principle, it is actually similar to the motion capture system already installed by Hellfire Entertainment, which captures the user's movements through a camera or sensor, and then interacts with the projected image.

In today's rapid development of science and technology, this kind of projection is actually not an uncommon thing. But......

Zhou Yan stared at the game tutorial in front of him, and then was taken aback again:

"Is this game fully manual?"

According to the tutorial, this "holographic version of Tetris" is completely operated through the interactive mode!

If the tutorial is correct, this is undoubtedly the first ever holographic interactive Tetris!

"This ...... Just kidding, right? Fang Chang's eyes were about to pop out.

As an avid fan of music beat games, he is still more interested in holographic games, and has tried holographic helmets and other devices, but ......

This kind of projection equipment can be called "hunting". Even if it's the first time he's seen it!

The light projected by the generator reflects the image on the holographic membrane around him, and it is already a miracle to use such a small device to produce a holographic projection of this level.

What's even more terrifying is that this thing is still interactive throughout the whole process!

"Let's try it, shall we?" Zhou Yan said as he stood still in front of the "Player 1 position" prompted by the screen in the air, stretched out his right hand and gently placed it on the virtual "cardboard" composed of green squares in front of him.

By this time. Fang Chang, who was still a little unable to lift his spirits, had already entered an extremely excited state, nodded busily, and stood at the "Player 2 position" at an angle of ninety degrees to Zhou Yan's position.

At the same time as he came to the position, the handsome young man also stretched out his hand and placed it on the red square in front of him.

"Smack!"

When the two of them "touched" the large block floating in the air at the same time, the block suddenly shattered into many small green pieces, and landed on the "blue floor" projected above the round table, forming something that looked like the mountain slope in Minecraft.

Followed by. There is a translucent figure of small squares, which is also green, and it begins to slowly fall from above.

Completely different from normal Tetris, in this three-dimensional Tetris game, this row can only be eliminated if the entire plane is filled with cubes.

This "puzzle"-like mode sounds cumbersome, and it's even more cumbersome to play in two-player mode because......

"Don't move the block while I'm cāo." Zhou Yan glared at the young man next to him.

"I'm sorry to ......," Fang Chang nodded a little depressedly.

While the two of them were talking. The block had fallen in the corner. New graphics have appeared.

――In this Tetris game, you operate in a 3D space. Two of the players are responsible for the operation of the falling graphics in two directions.

If you explain it in mathematical modeling, it is simply that one person is responsible for the X-axis and the other person is responsible for the Y-axis.

Only when it is determined that there is no problem in both directions can the falling figure be successfully embedded in its proper position.

In this way, the cooperation between the two players is important.

Except that the purpose of the two must be the same. When one player is doing the same thing, if the other player is also doing it, there is no doubt that both of them will be in a hurry.

If there is no tacit understanding of the "twin chariots", the two players need to operate in order to have any hope of passing.

But maybe it's because the phase is too poor. Even if it has been said that Zhou Yan will take the lead, the two who are currently in the game are still constantly making business trips.

Zhou Yan stretched out his right hand and tossed the descending cube to the corner. As soon as she put down her right hand, she saw Fang Chang flip the cube over, but it made another mistake and stuck it firmly upside down on the "floor".

"Brain problem?" Zhou Yan asked.

"You're the problem, this should be reversed and put on the other side, right? How can you play like that? Fang Chang was very unconvinced.

"Since I'm the first to do it, you should follow my rules." The girl in the trench coat frowned.

"You can't play Tetris at all!" Fang Chang was still unconvinced.

"What did you say?" Zhou Yan clenched his small fists.

If it was in the past, she wouldn't care so much about this kind of thing, I don't know if it was because of someone's influence, she always felt that she had begun to become a little sensitive in terms of "winning and losing".

Thinking that this young man actually said that he couldn't even play Tetris, there was a faint anger in the girl's heart.

"Go away." She whispered.

"What?" Fang Chang didn't hear it clearly for a while.

"I said go away."

Zhou Yan said and stood on the side of the round table, which should be the middle of player 1 and player 2, and opened his arms to start the operation of two players at the same time.

Just threw a rectangle in the middle, Fang Chang beside her finally couldn't help it, stepped forward and grabbed Zhou Yan's arm roughly, and dragged her aside:

"Don't think that a little girl can do whatever she wants, I was just letting you do it!"

"Want to die?" The pale girl also stood in front of Fang Chang without showing weakness and raised her little fist.

Just when the two were about to fight, the three-dimensional figure in front of them suddenly appeared, Zhou Yan and Fang Chang turned around at the same time, and what caught their eyes was the figure of Zhao Nuo who opened the "screen" and walked in.

"Don't make a fuss, you guys better stop trying it out for the time being, let someone else come."

-- Now it seems that trying to listen to the opinions of these two guys was a tragic mistake. It's better to let someone else try it out...... (To be continued......)
