In fact, they had already laid out some mechanisms when they were building the city wall.

This is OK to prevent some sneak attacks, and it must be in the right position.

After all, the defense line between the north and the south is too long, and it is almost impossible to spread some mechanisms into the entire defense line between the north and the south.

Besides, the two countries are in a good state of friendship. If there are business travelers here, you can't let everyone be buried in the government, right?

This is unreasonable.

It also lost its style as a great power.

However, it is possible to set up trap mechanisms in some places where people don’t often leave.

Or, you can start to set up patrol posts a few miles away from the city wall, which is also OK.

Of course, the patrol post only serves as a reminder.

They cannot be the main force of defense.

Qin Zicheng sighed countless times. If their clairvoyance had been better, maybe they wouldn't have to be so nervous.

Qin Zicheng's mind flashed, and he naturally thought of Feng Wuye.

Maybe, can she have a way?

The purpose of things like Qianliyan is to see further and then discover the enemy situation as soon as possible.

Feng Wuyao looked at Qin Zicheng with anticipation, and she had to say speechlessly that she thought of a solution.

After closing the door, Feng Wuyao entered his mustard seed space and began to search for if there was anything similar to Climate Eye.

I found two masks in the corner. This was plundered from the world in the past. I just thought it was fun at that time, so I threw it here.

Feng Wuye covered his mask on his face, and the scene in front of him changed.

I took it off and felt that I was not very satisfied with it.

After searching for a while, the space was out.

Feng Wuyao handed the mask to Qin Zicheng, "I bought this thing from a businessman before. I just thought it was fun at the time. See if it will be useful to you."

Qin Zicheng took it and tried it on his face. He felt that the scene in the distance was brought closer, and he could clearly see the grass leaves beside the courtyard gate.

Qin Zicheng was very happy, but found that there were only two such masks, and he was inevitably a little disappointed.

For their long defense line, there are indeed fewer two masks.

"It seems that this thing cannot be worn for a long time, which can easily damage the eyes. It is best to wear it in rotation. It is the limit for one or two people to wear it."

Qin Zicheng nodded, "Okay, I'll take this mask first, and an old craftsman from the Ministry of Works came. I'll ask him to see if he can create the same thing in the same way."

This is much better than the clairvoyance they used before.

Not only is the distance seen farther, but the picture is clearer.

Qin Zicheng went to find Song Lun and the old craftsman excitedly, hoping to make the same mask.

Of course, the most important thing is not the mask, but these two things on the eyes.

Feng Wuyao saw that he was so excited, and swallowed the words he said to him again.

Then, with a thought moving, a small box was added to the palm of your hand.

There are the best crystal stones inside. Without this thing, the effect of the Clanlie is probably difficult to achieve.

Feng Wuyao sighed, placed the box directly on the table, and then continued to take a nap.

Ji Gang and others did not expect that this thing is much better than the clairvoyance they currently use.
