Tie Hongyan replied: The middle vertical emitted silver light, and the silver light disappeared, appeared again, disappeared again, appeared again, disappeared again, appeared again, appeared again, appeared again, appeared again, appeared again, appeared again, appeared in total three times. The last time the silver light disappeared, it started from the top of the vertical, and more and more parts disappeared until the light below also disappeared. Then, the part outside the vertical began to flash three times at the same time, and the silver light was emitted. After the third silver light disappeared instantly, two silver highlights appeared on the left and right side of the same low place as the lowest point of the middle vertical. The two highlights flashed once and disappeared directly.

Ye Chi thought while listening to Tie Hongyan's words. After a moment, she said: I think we need to find the vertical position in the middle.

Tie Hongyan nodded and said: I am also thinking about this question. After all, the one that emits silver light first is the middle vertical. I think the position of the vertical should be between the two patterns on the wall, and the distance between the two patterns should be the same. What do you think?

Ye Chidao: Let's go to the middle and look for it.

The two of them arrived at the middle of the two patterns.

Ye Chi asked Tie Hongyan: What method should I use to find which vertical line?

Tie Hongyan said: Since the light emitted by the vertical line is silver, I guess it might have been tried with a silver hook.

So do we need to measure it accurately? Ye Chi asked.

It should be. Tie Hongyan said.

Take the rope on the silver hook and use the rope to measure it, and you can accurately find the same place as the two sides. Yechidao.

Tie Hongyan untied the rope on the silver hook, and then used the rope with Ye Chi to measure it.

After finding the exact position at the same center of the two patterns, Ye Chi placed the rope on the ground, letting one end of the rope stick to the wall.

It's the head, now we have found it, should we try it right away? Ye Chi asked Tie Hongyan.

Try it. Tie Hongyan said, just use the silver hook to scratch it from top to bottom.

Let's take a trance together.

After Tie Hongyan agreed, he held the silver hook with Ye Chi and drew the wall from a very high place in the middle.

Just as the two of them were scribing to the end, a silver light flashed from the place where the silver hook streaked, and then the silver light disappeared.

Silver light really appeared! Ye Chidao, it seems we did the right thing.

The position we chose when we started to draw was just high enough. Tie Hongyan said.

Yes. Yechi said that if he was shorter, he might not be able to flash silver.

The silver light disappeared quickly, just like the prompt I saw just now. Iron Red Flame said, should we draw the second stroke now?

Yes. Yechidao, let's start.

The two of them held the silver hook together and stroked from top to bottom in the middle.

The silver light appeared again and then disappeared.

Tie Hongyan said: Let's do it again.

Yechi nodded and then held the silver hook together, and scratched from top to bottom like the last time.

When the silver hook was scratched to the end, silver light emitted again, but this time the silver light did not disappear immediately.

Tie Hongyan said: Is it necessary for us to do something to make the silver light disappear this time?
