Chen Wen kept Xu Da and Chang Yuchun in the first place, but in fact, what he wanted to show them was the parachute!

However, I have been busy with glass and windproof goggles during this period. Chen Wen has not yet made a parachute that has only thought about a few signs.

"Two brothers! I haven't made the things I kept silent about, but I have two new objects on hand. I want you to take a look!"

Looking at Xu Da and Chang Yuchun's expressions of disappointment, Chen Wen took out the magnifying glass and windproof goggles by the table and said.

"What exactly are these two small objects?"

Seeing the magnifying glass and windproof goggles that Chen Wen put out, Xu Da and Chang Yuchun each took the same hand and played with it.

"Hey! Is this Liuli? Why does it look so clear?"

Xu Da was holding a windproof goggles in his hand. Although he didn't know what this thing was for, he was smart and could easily learn how to use it through details.

Xu Da put the windproof goggles in front of him, but found that the world in front of him was extremely clear.

This glass was called glazed in the Ming Dynasty, but because of technology, the glass produced by technology in this era was mixed with impurities!

Xu Da is also a well-informed general, but he has never seen such crystal clear glass without any impurities!

As soon as these windproof goggles were worn in front of me, Xu Da couldn't let go of them.

"Wacao! How can this glass still have the effect of enlarging it!"

"Brother Wen, have you imposed any spells in it?"

Chang Yuchun's reaction was even more outrageous. He saw him holding the magnifying glass in his hand and looking at his hand, but he found that the lines on his hand were magnified clearly!

Even the sweat glands on his hands that were as dense as holes could be seen very clearly!

"Brother Chang! The thing you are holding is called a magnifying glass!"

"I didn't impose any spells on this, they are all the power of the theory of Gezhi!"

Chen Wen just gave a brief explanation about Chang Yuchun's curious question.

As for the deeper theoretical knowledge content, even Xu Da’s smart little head may not understand it, let alone Chang Yuchun’s brain?

So he just talked about something easy to understand and fooled over. When he met someone who really understood this principle, he would not be too late to talk to the other party about the scientific knowledge and mystery in detail!

"Oh! This is really interesting in learning. This is amazing, right?"

Xu Da and Chang Yuchun couldn't help but sigh at the simple explanation made by Chen Wen.

Especially Chang Yuchun, he directly held the magnifying glass and refused to let go, and even placed the magnifying glass in front of him. Through the magnification principle, Chen Wen and Xu Da saw Chang Yuchun's Kazilan's big eyes!

"Brother Chang! If you like this thing, I will make two more decisions later, and I will give you one to one!"

Seeing that Chang Yuchun couldn't put down his love for the magnifying glass, Chen Wen also found it a little funny and quickly told him and Xu Da.

You should know that when Chen Wen gave something to others, he never favored one or the other. He could see that Xu Da also liked this magnifying glass, and he repeatedly wanted to grab the magnifying glass in Chang Yuchun's hand!

It was not until Chen Wen said that each person would give him one, and then he gave up and said, "Okay! With this magical magnifying glass, I don't need to work so hard to see the map in the future!"

Xu Da’s purpose of magnifying glass is exactly the same as Chen Wen. He planned to use it to look at the map!

Seeing two middle-aged and elderly men in their fifties snatching them up for a magnifying glass that was like a toy in their later generations, Chen Wen laughed a little.

But he followed the two of them. Anyway, the brotherhood between Xu Da and Chang Yuchun would not be hurt because of this snatch, so it doesn't matter!

However, after snatching for a while, Xu Da remembered that there seemed to be something to report to Chen Wen.

"Brother Wen! Look at my memory!"

"I just wanted to report to you about the lurking situation of the spy, but when I became obsessed with this strange thing, I suddenly forgot!"

After stopping to compete with Chang Yuchun for a magnifying glass, Xu Da thought about it for a while before he remembered what he was going to do!

"It's okay for Brother Xu! Just talk to me now!"

Seeing that Xu Da was here to report the progress, Chen Wen couldn't help but say a little formally.

"Brother Wen! Today, according to your wishes, I will send the soldiers of the Shenji Camp who had been trained by the spies of the Jinyiwei to lurk in Helin City!"

"It's just that Helin City is too precautionary now. I have been useless and finally sent them in!"

Seeing that Chen Wen's expression became a little serious, Xu Da also put away his carelessness just now and reported the situation to Chen Wen.

"Oh? Brother Xu might as well tell me what method was used?"

Chen Wen is quite familiar with Helin City’s current prevention and deployment.

The entire city is currently built by Naha, but after the rumors ferment, it will be unclear!

So Chen Wen was still quite curious at this time, what method did Xu Da use to send the spies in?

"This is not a problem! Although Lin Cheng emphasizes defense, the people inside always have to eat!"

"I happened to find out that the food transport in Helin City was secretly transported by a tribe next to it!"

"So I asked someone to capture some important figures from the tribe and coerce them to cooperate with us to send people in!"

"In this way, our people were secretly sent into Helin City through truckloads of food!"

"But once a week, the Beiyuan people in Lincheng are in food supply! If you want to know what our spies are in and what information can be brought out, you have to wait for a while!"

"At that time, the information in Helin City and some planning progress of the spies will be sent out as the food transport team leaves Helin City!"

When Xu Da heard Chen Wen ask about the method, he didn't hide it from the other party. After all, Chen Wen is the head coach and has the right to know all the information about the battle situation!

"Well! This tribe is not reliable. You must not lose your chains on them!"

Seeing that Xu Da had made arrangements, Chen Wen didn't say much, but asked questions about reliability and safety.

"Brother Wen, don't worry! I basically tied up the elders in their tribe! Even the shamans of their tribe were tied up by us!"

"You must know that these Northern Yuan people attached great importance to their shamans!"

"I will definitely help us honestly!"

Hearing Chen Wen's question, he seemed a little worried. Xu Da explained directly, so he made Chen Wen feel completely at ease.
