"Isn't this algorithm right?" Looking at the chessboard in front of him, Gray Yuan was a little disappointed. "I thought it would work out this way..."

"That's pretty much it," Chiba smiled delicately. "You're basically done with this question."

"Huh?" Gray Plains Wai showed a stunned expression. "Done?"

"That's right," the smile on Chiha's face widened. "Although this question is taken from "The Theory of Hair and Yang", it is indeed a bug question."

"What?" Gray Yuan Wai suddenly had a feeling that he had been deceived. “bug？”

"Yes," Qian Yu tilted his head, and then removed the chess pieces from the chessboard one by one, leaving only the original ones. "The accepted result is that the problem is unsolved, and black is unsolvable."

With that, Qian Yu put out another set of change diagrams.

"How did you get here?" Gray Plains blinked. "If I'm not mistaken, this was the way to do the problem at that time, and the black pieces died in a few moves?"

"yes," Chiba nodded. "You see, this is the solution to this problem when it was first developed, but this solution is actually a bit taken for granted, so recently someone has proposed the most powerful step on the basis of additional research. Although it turns out that black is still lifeless as long as white is dealt with properly, it is already far more advanced than the only solution that seems to be very certain from those who have come before him. ”

"In fact, there are many different solutions along the way, and there are many people who claim to have helped black find a way to survive, but in fact they all failed." Saying this, Qian Yu let the black piece break through at another point. "I've seen dozens of moves from the side, I've seen rushing out and fighting white on a large scale, but these methods can't be done because they don't have enough energy."

Saying this, the black and white pieces have been entangled all the way to the other side of the board, but the black pieces still cannot survive, and in the end they still can't get rid of the situation of pure death.

Gray Yuan looked at the chess pieces, not knowing what he was thinking.

"What's wrong?" Chiba keenly sensed that Gray Plains seemed to have something on her mind.

"I remembered the story of Matsumoto City," Gray Hara sighed as he glanced around. "You say, this time this incident, is there only a red Siamese cat?"

"What do you mean?" Qian Yu frowned slightly.

"You say, will our former friends be involved?" Gray Yuan Ai took out a sunspot and played with it in his hand.

Undoubtedly, she was referring to the organization.

"I don't think so, after all, it's too devastating," Qianyu's brow furrowed even tighter. "It's good to say that it is good to use it for research, but it seems that it is difficult to control the epidemic situation when it is practical."

It's not impossible for the organization to get involved in such a dangerous thing, but it's a foolish thing to do.

"What do you think will happen to black?" Gray Yuan seemed to say what was on the chessboard, but it seemed to mean something. "Maybe the power of black chess is still huge, but in the end it is a clean death situation... After that, those scattered pieces may not be able to escape the hunt of white. ”

"Maybe there will be pieces that will be captured, maybe there will be chess games that will fail, but more pieces are still alive," Qian Yu said softly. "Those pieces that are not caught in the fight, but are in inconsequential places, are safe."

"And before that," Chiba added. "Black doesn't have to be the only piece of chess."

Removing the last entanglement extension of Othello, Thousand Feathers placed a black piece in the same place where the original Othello was entangled—so that as long as Black tried to extend in this direction, it could communicate with the external potential and successfully break through the encirclement.

"Black looks like it is surrounded by many faces, but it's not necessarily dangerous. What's more, the two of us are far away from the battlefield, even if that piece of chess dies, it won't affect us. Qian Yu looked at Gray Yuan's mournful eyes and comforted.

At this moment, such a conversation suddenly came from beside them.

"Captain, what's the matter with me?" A young staff member said to an older staff member who was watching them.

"Huh?" The captain looked surprised. "I didn't look for you! Are you mistaken? ”

"Won't it?" The staff was stunned, and then showed a helpless expression. "I was taking care of the Suzuki consultant just now, and then I suddenly heard you call me, and then said that you are waiting for me in the recreation room here, so I packed my things and came to you."

"It's nonsense, I've been staying here, how can I go to you?" The captain frowned.

"Huh?" This time it was the turn of the staff to be dumbfounded. "This ......"

"Is there anyone else in the restaurant?" The captain suddenly thought of something and immediately asked.

"Those guys in the kitchen must still be over there, right?" The staff thought for a moment and said. "But maybe the waiter won't be there?"

"Let's take a look," the captain seemed to have thought of something, and immediately asked the staff to go with him to the dining room to have a look.

"......" with a somewhat subtle look in his eyes, Qian Yu looked at such a somewhat subtle conversation.

"What's wrong?" Gray Plains asked.

"I just always feel that something is not right," Qian Yu looked at the two of them walking towards the restaurant. "It's a subtle feeling......"

"Aren't you going to take a look?" Gray Yuan looked at Qianyu's expression, and seemed to see the doubts in his heart.

"Uh......" Qian Yu looked at Gray Yuan Ai, and hesitated after a moment. Then I'...... Check it out? ”

"Just go," Grayplain shrugged. "If you want to go, just go."

……

When Chiba arrived at the restaurant, he found that there were five people in the restaurant after counting the two staff members just now—the drunk Mori Kogoro and Suzuki Jiroyoshi, two staff members, and then one staff member.

"Really," the new staff members accompanied Kogoro Mori and Jiroji Suzuki, helplessly looking at the two staff members who had just arrived. "Are you guys like that, have you left Advisor Suzuki and Mr. Mori here?"

"You are?" The captain glanced at him.

"I've just been transferred to the queue of service personnel," the staff member said. "My name is Doi, please advise."

"Okay...... "The captain sighed and looked at the staff beside him. Are you hallucinating? It's not like a newcomer to apologize? If it weren't for him, Advisor Suzuki and Mr. Mori would have no one to take care of. ”

"It's okay, it's what I'm supposed to do." At this moment, the smile of the new staff member is quite bright.
