Actually, the plan started the night before.

In the afternoon of the same day, Ye Dill had confirmed all the routes and the entrance to the ventilation duct, and she told Bai Qi the entrance point through the [communication rope], and told all the plans for the future.

So that night, Bai Qi used the [Replica Shadow Puppet] to make a replica of himself, and then pasted the [Unobtrusive Card] on himself.

The compartment he lives in is the furthest one, with no players directly opposite.

As long as he does all this while lying on his side on the bed, neither the player on the opposite side nor the outside surveillance can detect it.

By the time it was time for dinner, the transparent wall opened, and the invisible, self-contained body and replica came out of the cubicle and entered the cafeteria together.

The replica completes the task of eating dinner, while the main body stays in the cafeteria until dinner, when all players have left and the cafeteria door is closed.

This is what Bai Qian inadvertently observed when he was exploring the outside with the [Unobtrusive Card] before.

When the door of the canteen is closed, the monitoring in the canteen will also be closed.

Probably because the ability of the spirits is not enough, it will be difficult to run many rooms at the same time.

So when it is determined that a room is free of players and the door is closed, the Avatar will choose to turn off the monitoring in that room in order to have more energy to run other areas where it is needed.

It just so happens that the entrance chosen by Ye Dill is the vent of the canteen.

After everyone left, the cafeteria door was closed, and the monitoring was closed, Bai Qi entered the ventilation duct.

Bai Qi walked a little way into the ventilation duct and met a replica of leaf dill waiting at the fork in the road.

Then Bai Qian handed the [Unobtrusive Card] to the replica of Ye Dill and pasted the replica of Ye Dill on his body, and came out of the ventilation duct of the cafeteria until the next morning.

When it was time for breakfast, Ye Dill entered the cafeteria, and entered the only monitoring corner in the canteen under the pretense of observing whether people could hide from the back of the canteen door.

It was also there that leaf dill and replicas were swapped.

Ye Dill stuck the [Unobtrusive Card] behind the door and did not move, while the replica and Jin Xiaohua converged and left the cafeteria together.

After the cafeteria was closed again and the monitoring was also closed, Ye Dill left the [Unobtrusive Card] under the table in the corner of the cafeteria, and then climbed into the ventilation duct on the table.

When the cafeteria opened again at noon, Gu Qingqiu sat in the corner of the cafeteria.

In the past few meals, Gu Qingqiu has been sitting in that corner every time, and Gu Qingqiu has an unsociable personality, so this behavior will not attract the attention of others.

Moreover, Gu Qingqiu acted alone most of the time, and others did not dare to pay too much attention to him.

In addition, when eating, the players are always talking and chatting, noisy, and will stand up and gesture when they are excited.

As long as Gu Qingqiu seized an opportunity for someone to stand up and block his figure, he could stick the [Unobtrusive Card] on his body, hide himself, and quietly wait for the cafeteria to close.

And the fact was just like Ye Dill planned, because there was no movement, even the spiritual creature didn't notice that Gu Qingqiu disappeared at that time.
