Zixu didn't dare to be careless. He first observed the structure of the entire telescope and found that there were several small holes in the telescope. He could see that there were screws inside. Then he took out an extremely small knife from his sleeve, opened the screws, then took out the mirror of the telescope, carefully observed the sunlight, and then took out a small magnifying glass from his arms and looked at the mirror.

God knows how much is in Zixu's clothes.

Xu Shu and Gan Ning looked at each other, not understanding why Zixu was so concerned about a glass mirror. Could it be that he was also planning to transport it to the Western Regions for sale?

Zixu slowly put the lens in his hand back into the slot in the copper tube, and then said with a serious expression, "This thing is indeed not from the Red Star Camp!"

Because telescopes have high requirements for workmanship and involve military affairs, only Hongxing Glass Factory has produced them so far.

"Although the quality of this glass is also very good, it is still a little different from the glass in our Hongxing Camp. There are extremely small debris inside that cannot be seen clearly. Even so, it can be used. The other party's glass production technology cannot be underestimated.

Did Manager Meng report this?”

"It was not confirmed before, so it was not reported."

"I think this matter is of great importance and must be reported as soon as possible and a special person will send this item to the general of Liaozhou. The glass comes from the general's sect. I think only the general knows what the matter is."

Xiao Meng nodded and immediately said goodbye and left.

"Master, what's going on?" Gan Ning asked immediately.

"I don't know either. But after seeing this thing, I just felt a whim... I felt a little ominous." Zixu shook his head with a gloomy face.

People who practice cultivation like him can sometimes sense something that is difficult to explain.

"Is there a natural disaster again?" Gan Ning looked at the sky and asked.

In recent years, natural disasters have continued, and Gan Ning is almost numb to natural disasters.

"Hey, I'm not good at studying. If my mentor is there, I might have calculated it more clearly." Zixu shook his head, not explaining what that unknown thing was.

"What is the Taoist priest's mentor?" Xu Shu asked at Zixu.

Zixu was silent for a while and slowly said, "Great Master... Zhang Jiao!"

really!

Xu Shu did not discuss the fact that Zhang Jiao was Zixu's master.

"Okay, there is a dedicated person to deal with this matter. We don't need to think about it. Do you want to go and see the school in Chang'an?"

"School? Just what I wish!"

Xu Shu pressed down on the doubts in his heart and continued to visit Chang'an City with Zixu.

After all, they are going to set out for Hebei tomorrow.

On the other side of Liaodong, Gongsun Du just received a dangerous war report.

Because of the activity of the cavalry led by Ma Chao, Jiandu did not receive any warning of the loss of Fang County and directly faced the fierce attack of the 12th Army.

The 12th Army's eighty mortars were bombarded in turn, which was extremely terrifying. In the battle report obtained by Gongsun Du, the description of it was that the heaven and earth were shocked, and the sun and the moon were lost. People dared not stand on the top of the city, and the livestock could not be scared to death.

Gongsun Du, who had never seen the power of a firearm, had no idea.

No matter how strong the Hebei army is, it must pay attention to the basic law. It will shock the heaven and earth, and the sun and the moon will lose its light. Why don’t you say that the Hebei army’s fighting spirit turns into horses? It’s so terrifying?

Wait...What is fighting spirit?

Anyway, Gongsun Du felt that the Beiyan recommended by Liu Yi was unreliable. He had said before that he could stay for a few months. Now, he came to ask for help on the first day.

Ahhhh!

Gongsun called Liu Yi over and cursed him in a daze.

"Look, this is what you told me about my first best general in Liaodong in the future? My best generals in Liaodong are all like this. Can I still sleep at night?"

Liu Yi took the letter of help, frowned and said, "Ming Gong, the person who escaped from Yuan Shao before also said that Ma Ziyu had something called artillery in his hand, which was extremely powerful.

The Battle of Jieqiao in the past was because of artillery that Yuan Benchu ​​caught him off guard, which made Ma Ziyu get Jizhou and swept across Hebei.

Therefore, I will think that the content of this letter is not false. Although Bei Yan is brave and wise, he is inevitable to panic in the face of this unprecedented weapon of siege."

"What? Is it because of this artillery that we won't fight in this battle? I will go to see Ma Ziyu with my own head?"

"Ming Gong calmed down his anger. Although the artillery was sharp, it was definitely not invincible. Bei Yan was just young and had no experience. I wrote a letter to him carefully find the weaknesses of the artillery, and good news would come.

And we can use Jiandu City to test out the characteristics of artillery. As long as we can think of ways to restrain the artillery, even if Jiandu is lost, we will definitely win in the end!"

Liu Yi's words slowly extinguished Gongsun Du's anger. He nodded and said, "Well, let me do it like this. Tell Bei Yan that he would have to defend as long as he had said before. Even if only one soldier and one soldier were left, he would have to guard the danger for me!"

"promise!"

Seeing this, Liang Mao next to him felt that it was an opportunity, so he stood up and said, "Ming Gong, I think it's time to contact the princes and the court of the Central Plains."

Gongsun Du nodded.

He was originally preparing to have some achievements, such as asking the Hebei Army to leave thousands of lives under the city of Liaodong before sending a letter of help. Now it seems that it is time to get early.

Gongsun Du asked someone to draft a letter, and Liang Maoze handled the military affairs for a while and returned to the account to rest.

Liang Mao returned to the account and quickly found a book from the book box, then searched for the words he needed, wrote a secret letter, and then came to the postman in the army with the letter and asked him to deliver it to his mansion.

This letter appeared in Gongsun Du's hands half an hour later.

Gongsun Du opened the letter and looked at it. He found that they were talking about some trivial matters in the military. Then he asked his family for safety and nodded and handed it to the postman who came to report and said, "Send it here. If there is any reply, send it to me first."

"promise!"

Although Gongsun Du was using Liang Mao, he did not really feel relieved about Liang Mao. Liang Mao, Jia Zhong and others also knew it well, so they would definitely not understand the letters unless they had a codebook and decryption method.

The letters from these senior military officials were delivered by fast horses, and they arrived in Xiangping in just one day.

After Jia Zhong received the letter, he immediately took out a book like Liang Mao and began to decipher it.

A quarter of an hour later, a long list of unseen radio waves flew towards the Liaodong Operations Command, which was moving towards Fang County.

"The 12th Army put a lot of pressure on Liaodong. It started asking for help so soon."

Ma Qiang returned the telegram to Guo Jia and said, "Fengxiao, I am very interested in what kind of behavior those who received a letter of help from Gongsun Du will perform. What should I do?"
Chapter completed!
