Datang: Signed in for Seven Years and Was Exposed by Empress Changsun

He personally dispatched, asked Shouhou and others to hold a farewell ceremony, and sent Li Shimin and others to the gate of the cottage.

At this time, the gate of the cottage was tightly closed, which was different from when they first came in.

At the same time, because Empress Zhangsun was critically ill when she came in, they didn't pay attention to it.

So when Li Shimin and others came to the gate of the cottage, they couldn't help being stunned.

They all stared wide-eyed, looking at the gate of the cottage in horror.

Is this the bandit's cottage?

How can it be?

This is stronger than Chang'an City, right?

I saw the high wall of the cottage was erected, and it was wrapped with a layer of iron sheet.

On the city wall, there are sharp blades and strange launching tools.

This thing is a huge box, at first glance, there are hundreds of thick bows and arrows inside.

Li Shimin and others have never seen such things, but they can guess their function.

If there is an enemy coming, the bow and arrow in this box will definitely be shot out.

There are more than a hundred arrows in a box, and more than ten boxes, how many thousands of troops have to be shot and killed?

In addition, the gate of the cottage looks unusually tall and strong.

You can tell at a glance that it is made of pig iron.

From the perspective of Li Shimin and others, even exhausted soldiers could not break through this kind of iron gate.

This f*cking, impregnable cottage!

Is this really a cottage?

"Keming, Xuanling, auxiliary machine, have you seen such a city gate?"

Li Shimin asked in shock.

His eyes are already a little demented, and he feels that he can't digest it.

"No, never."

Du Ruhui, Fang Xuanling, Changsun Wuji and others who were questioned shook their heads in astonishment.

They can't explain these things in front of them, and they have completely exceeded their cognition.

Never seen again...

What they experienced in Lianyun Village in the past two days made them feel like they were dreaming.

It seems that everything is not so real, but everything is true.

"The chief of the village is going out, open the gate of the village quickly!"

The thin monkey walked in the front and spoke loudly.

The voice fell.

There was a sound just now, and the big iron door was slowly opened.

Li Shimin and others stared at the gate of the village, wanting to see what they saw.

However, no matter how they looked at it, they didn't know how the gate of the village was opened.

But one thing they can be sure of is that this kind of gate cannot be opened by manpower.

"Li Hong, how was this door built?"

Li Shimin asked tremblingly.

He has an idea, if this kind of gate is made in an important city, such as Chang'an City, such as a frontier city.

Doesn't that mean that you don't have to worry about being detained by foreign races and killing your own compatriots?

Thinking of this, Li Shimin trembled with excitement.

"It took me three full years to build this door, so don't think so much, Your Majesty."

Li Hong waved his hand and said.

Although he didn't know exactly what Li Shimin was thinking.

But he can still guess the general idea, so he dismissed his thoughts.

At that time, in order to make this door, he had consumed many rewards from the system.

Now it is difficult to get another door like this out.

"Ok."

Li Shimin sighed helplessly.

A lot of disappointment flashed in my heart.

He deeply remembers this structure in his heart.
