No matter when, Kuro Kudo's desire to leave this world has never changed.

As for why he was rescued by Mao Lilan - that was his last cry for help from this world.

Until he asked Akai Shuichi the meaning of being alive, it was his cry for help.

Anyway, if you give me a reason to live, I can survive. Please save me.

This is what Kurokudo wanted to say.

So he asked the question. He asked the FBI agent who, no matter what he had been through, remained firm in his belief and walked unwaveringly towards his goal.

He asked: "What is the meaning of life?"

The FBI did not give him a satisfactory answer. He said, "There is no meaning in life, but as long as there is a reason, it is enough to live."

The reason.

The boy who fell into darkness thought that his Shiho was dead, Ayang was dead, and his sister was also dead.

He has no reason to live.

Then just go die.

After all, there are many reasons to die.

He thought so, and so he did it.

Lu Qi sorted out the cause and effect of the matter, and began to think about how to reasonably make Hei Kudo rekindle hope of asking for help again.

After thinking about it, he only thought of Lu Jiu.

Let this guy who does not exist in the original script "sharply" notice that something is wrong with Kuro Kudo, and then help him.

After finalizing the general plan, Lu Qi began to think about the details.

For example, how can he get Riku to cooperate with him?

After thinking for a while, he turned around, opened the bathroom door, then opened the bedroom door and came to the living room.

He probably has an idea.

When the boy opened the door of the room, there was a faint knock, which mixed with the sound of the door lock opening and was not noticeable.

At least not the big detective in the living room.

But Lu Jiu, who was wearing the shell of Fukuzawa Yuji and also practiced swordsmanship, discovered it sharply.

This little sound brought back memories.

Before he and Luqi broke up, little Luqi was very attached to him. Even when it rained, thundered and lightninged, he would carefully knock on his door, gently.

If it were someone else, they probably wouldn't be able to hear the slight knock on the door at all, but Riku, who had practiced swordsmanship for a long time, had sharp five senses and could easily detect the knock on the door.

Then she would open the door, tell the little deer a story, and then hold him to sleep.

Later, whenever Xiao Luqi had difficulties, he would gently knock on the door in this way, and Lu Jiu would tacitly take him to his room, and then solve his problems or relieve his emotions.

Over time, this gentle knock on the door became their unique secret signal.

Although after that incident... he never heard such a knock on the door again.

It only took a few seconds from falling into memories to coming back to his senses, and soon Riku and Conan turned their gazes to the black-haired boy who came out of the room.

He wasn't sure if the sound was intentional or accidental.

The black-haired boy raised his eyes and looked at the two people in the living room. His ocean-blue eyes seemed to be quieter than usual, but with an unspeakable firmness.

It was as if he had found his final destination.

Conan subconsciously felt that something was wrong, but after looking carefully, he felt that there was nothing wrong.

The boy was usually so quiet, and there was no change now.

He couldn't see what was there.

Lu Jiu was stunned when he saw Lu Qi. He seemed to have never seen Lu Qi like this before.
