…

After coming out of Cao's Mansion, all of Wu Liang's ideas were successfully realized and he was in a good mood.

So when he returned home, Fu Ou Duan called Dian Wei, Liu Jinshui and others together, cooked meat and drank wine to celebrate, and worked hard until midnight before returning to visit and rest.

When he got up the next day, another inspiration flashed in his mind.

So I got up immediately, got charcoal and linen, and sketched for a long time. Then I took the drawings to the city and found a cobbler's shop.

"Master Jun, what is this? Does it look like a grimace?"

Holding the drawings Wu Liang brought, the cobbler looked at them for a long time without understanding what they were.

Wu Liang smiled, pointed at the drawing and said, "Don't worry about what this is, just help me make it. Your reward is indispensable. By the way, this ghost face is hollow near the mouth. Look carefully. Don't do it."

I got it wrong."

"Okay, how much do you want?"

the cobbler asked again.

"Let's get twenty pairs first. I'll come back to you if I need them."

Wu Liang thought for a moment and said.

What he has made now is actually a gas mask. If he encounters a tomb with bad air and even uses poison gas to prevent theft, it will come in handy.

Of course, also subject to the limitations of materials and technology of this era, Wu Liang was unable to make a gas mask as sophisticated as that of later generations.

But you can still try something a little simpler, and it will always have some effect.

For example, he designed the "ghost face" near the mouth to be hollow.

At that time, you only need to burn some charcoal, then crush the charcoal, wrap it in linen, and stuff it tightly into the hollow ghost face. If you wear it on your face like this, you can still resist the intrusion of poisonous gas as much as possible in a short period of time.

.

The charcoal bag can also be taken out, replaced and reused.

Think back.

The small drum of unknown purpose, the Luoyang shovel, the engineer shovel, the Suihou Pearl, the Yin Yang Stone, the Flying Tiger Claw...and now there is a gas mask.

Tomb robbing tools have become more and more comprehensive, and this is officially on the right track.

…

Three nights later.

The lights in Cao's Mansion are brightly lit, and a lobby has been transformed into a banquet hall after simple renovation.

Wu Liang came to Cao Mansion with a very formal invitation made of bamboo slices, and was quickly invited into the hall and placed in a central position.

Boss Cao is also interested.

When he first arrived, he was not allowed to sit too far forward so as not to cause dissatisfaction to others.

He was not allowed to sit too far back, lest others would look down upon him as an insignificant character.

At this time, there were already some people in the banquet hall.

Although I dare not say that all of these people are Boss Cao's trusted generals, most of them should be generals whose names can be mentioned in history.

It's a pity...Wu Liang couldn't recognize any of them just by looking at their faces without knowing their identities.

These people were originally greeting each other and chatting. When they saw Wu Liang sitting in the middle seat after being introduced, they all showed curiosity.

Some people even started whispering, without even thinking, they must be discussing who this new face is.

How could he be able to sit in this position?

Especially those who were placed in positions below Wu Liang, in addition to being curious, seemed to be slightly dissatisfied.

Wu Liang didn't take the initiative to talk to them. He just felt a little uncomfortable being stared at by these eyes, so he simply closed his eyes and calmed down.

After a while.

"Captain Wu, are you okay?"

A familiar and somewhat teasing voice sounded, and it sounded like it was Cao Zhen.

Wu Liang opened his eyes and saw that standing in front of him was not only Cao Chen, but also a young man with sword-like features and a cold and arrogant temperament, who was about the same age as Cao Chen.

This person is none other than Cao Ang, Cao Zixiu, the eldest son of Boss Cao.

Wu Liang had met Cao Ang once before when he first met Boss Cao in the camp on the outskirts of Tan County, but at that time it was just a brief meeting and they didn't even exchange a word.

"Colonel Wu."

Cao Ang cupped his fists and gestured to Wu Liang. Although he was still a little raw, he probably already knew his identity and what he was doing, so he showed more respect.

"I've met the eldest son."

Wu Liang also stood up and paid his respects.

Seeing this scene, everyone was undoubtedly more confused about Wu Liang's identity, and their eyes became more curious.
