Early the next morning, Xu Huabiao came to the south gate of Luoyang to see off the army that went out to Hongnong.

Pei Zhuhyun was busy filling in the big hole dug by Xu Huabiao because he wanted Pomeranian to smile, so naturally he didn't follow, and Xian Enjing, the nominal military commander in Luoyang, became the well-deserved commander-in-chief of this rescue of Hongnong.

It's just that she still has to gather the part of the army that is harvesting crops around Luoyang who have the strength to join the Shence Army, and then lead the troops to Hongnong, this process will take five or six days, so this time it is actually the Shence Army's own main formation.

Pei Xiuzhi led the team, followed by the four deputy capitals, and 3,000 cavalry.

However, Pei Xiuzhi was a little unconfident in herself when she left, after all, this was the first time she had led a team of more than 500 people, and she really had no experience.

In order to make this girl, who has few opponents in the world to fight, but when it comes to self-confidence, I am afraid that she is not as confident as Lin Yun'er, who has always been a low-key guard, but only one day late, Pei Zhuhyun was urged by Xu Huabiao to set off quickly to catch up with the army.

Originally, Bae Joo-hyun was still thinking about setting off with Xian Eunjing.

And five days later, Xian Enjing, who followed the reorganization of the two thousand cavalry in Wancheng, finally took the Lin Yun'er embroidery for several years, and then Xu Huabiao prepared for a long time before printing and dyeing the side of the strategy written by Xu Huabiao himself, which has many indescribable colors and lines, at first glance it is just very messy and dirty, but Xu Huabiao thinks it is very beautiful The Shence Army military flag also rushed to Hongnong with Xian Enjing.

Although Xian Enjing didn't understand the use of the military flag that Xu Huabiao insisted on, it was ......

Well, the lord's requirements, subordinates don't need to understand.

And after the army set off, Xu Huabiao also devoted himself to his own work.

In the blink of an eye, it's a month.

I went to the Ministry of Industry every day during the day, discussed with Zheng Caiyan and some craftsmen in the Ministry of Industry the design drawings of the cold forging armor and crossbow that Xu Huabiao handed over some time ago, and then experimented together.

Before Xu Huabiao drew the design drawings to let the Ministry of Engineering build the hydraulic press has completed two generations of replacement, according to Xu Huabiao's "simple steam engine" theory, after the power of the hydraulic press strengthened, now in accordance with Xu Huabiao's requirements in the stamping machine to create cold wrought iron sheets, even, there have been some cold forging armor has been manufactured, according to Xu Huabiao's plan, this is the future of the Shence Army's standard equipment, nearly a thousand years earlier iron floating slaughter......

However, the refined steel required for the hand crossbow is still very early before it can be made.

However, the design idea of Xu Huabiao's hand crossbow inspired some craftsmen in the Ministry of Industry to make some improvements to the current crossbow, and the power, range and operation have made great progress compared with before.

Of course, this kind of thing is not suitable for the Shence Army and the Shenji Battalion, it is too cumbersome, but if it is used by the infantry to defend the city, the power of this thing is terrifying.

Of course, these are some of the many things that people in the Ministry of Industry have to do, but they are not what Xu Huabiao, who likes to have nothing to do, wants now.

Now what he wants to do is something else.

"Lord Thorn Shi, there must be something wrong with the whole recipe now, it's not that the furnace temperature is not enough!"

"This ...... I just remember to add limestone...... Why don't you add some soda ash to it? Well, also, can you consider adding some feldspar to it? ”

“…… Is it okay to add things like this? ”

"That's what an attempt!" Xu Huabiao smiled and patted the researcher's shoulder, "Research is to keep trying!" After trying all the impossible, you can find the possibility! Come on, let's try again! ”

“…… Well, I'm going to get some materials. The researcher nodded, and walked out of the secret research room located beneath Luokoucang.

Xu Huabiao sat on the stool next to him a little relaxed, picked up the water bowl on the table, and poured it into his mouth.

Glancing at the one that had just come out, it was supposed to be a furnace of glass of slowly condensing liquid.

A pile of glass beads of various shapes.

It's beautiful, but it's not what I wanted!

What I want is liquid glass, and then I can cool and pour it......

He wants to use it as a telescope now! Before, on the Yangtze River, he had to rely on Lin Yun'er beside him to help her guide, although he didn't say it at the time, he still felt very ashamed in his heart.

As for the telescope, it is not difficult for Xu Huabiao to design the optical path, the key is to make a set of lenses with a specific focal length!

Of course, these glass balls with the transparency of quite good, the size of a girl's fist, can actually be polished a little, and then they can be sold as handicrafts.

There's no need to throw it away!

Just as Xu Huabiao stood up again and squatted back into the freshly baked glass manure pile to look through the naturally formed masterpieces that could be used as a collection, the basement door opened.

"It's fast this time...... Yes! You're back! ”

Xu Huabiao turned his head and saw the person coming in behind him.

A big smile hung on his face.

"Childe, what are you doing...... What is this? Yes! It's so beautiful! ”

"Glass! Do you like it? Pick two and play with them! ”

"Play? This one...... Is it appropriate? ”

"What's out of place? It's a scrap in the first place, just play with it. ”

“…… Waste? Such a beautiful ......."

"It's useful, and it's not just for the sake of looking good."

"Oh...... Then I'll take a look at ......."

"Look!" Xu Huabiao smiled and stepped aside.

Lin Yun'er squatted to the place where Xu Huabiao was squatting just now, and rummaged in it.

Soon.

"I want both!"

Lin Yun'er lifted two glass balls, which were already relatively round.

"Well, you just take it...... By the way, Jieqiong is back, right? Bring two to her too...... And Yun Xi ......"

"This ...... The princess didn't come back. ”

“…… You've been gone for so long, and no one has picked me up? ”

"This ...... The princess would not come back with me, and I could not force her to come back. I persuaded her for a month to no avail. Lin Yun'er said a little worriedly.

“…… What the hell is she going to do? ”

"I think the princess may only say ...... to your son," Lin Yun'er had a weak expression, "Why don't you go to Xuchang?" ”

"What am I going to do in Xuchang......

"When I came back, Lord Li Xiuman asked me to send a letter to Gongzi, and asked you to help him go to attack Yecheng together."

"I'll help...... I just don't want to help! And didn't Bae Joo-hyun already help Jung Yoon-ho come up with an idea? Do you still need me? ”

"Huh? Jung Yoon-ho's idea was from Lord Joo-hyun? No wonder! Lin Yun'er's face was abrupt, "I'll just say, how could Zheng Yunhao, who has always been well-behaved, suddenly come up with such a trick...... Dig a small ditch, then drink water directly into it, and use water to make a moat that separates Yecheng...... Well, it's really like Joohyun-sama's style! ”

“…… I'm definitely not going to Xuchang. Xu Huabiao shook his head.

"But the princess told me before I came back that the Son of Heaven also wants you to go to Xuchang, as if there is something to discuss with you......"

“…… Then I can't go. ”

"Childe...... Isn't it okay to resist the decree and not obey it? ”

“…… Well, I'm busy! Oh! That's right! Let's go, Yun'er, let's go to Hongnong! ”

“…… Childe, you're not going to do it! ”

"I don't want to see the Son of Heaven now......"

"Why......" Lin Yun'er still didn't understand.

"Well, let's bring all the people from the Shenji Camp who are still in Luoyang and go to Hongnong together."

“…… Bring it all? The battle situation on Hongnong's side is not good? Lin Yun'er was stunned, and she couldn't care about what she just said.

"It's okay! At the beginning, although the soldiers led by Oh Jong-hyuk surrounded Hongnong City, Eun Jing commanded the Shence army to constantly attack outside, and Zheng Xiujing commanded the Chang'an reinforcements led by Park Ji-yeon, who had arrived in advance, to go out of the city from time to time to attack, making Oh Jong-hyuk in a dilemma. Xu Huabiao said with a smile, "What Pei Zhu-hyun gave me is that Liu Xianhua of Xiliang, who is waiting for Sun Shengwan to contact, and Han Geng's cavalry that Cheng Xiao went to Wuguan to transfer, and then the east, west and south sides are flanked at the same time, and Zheng Xiujing and Park Ji-yeon break through the middle and defeat Oh Jong-hyuk's army in one fell swoop. It is estimated that the time should be in the near future, and a general attack will be launched. Let's go see the bustle and then ...... Well, make some other arrangements. ”

"Is that so...... It's not impossible. Lin Yun'er smiled and nodded speechlessly, "If you don't want to go to Xuchang, this is also a good excuse." ”

"Then you clean up, by the way, how many people from the Shenji Battalion are left in Luoyang City?"

"This time I brought some people back from Luoyang, and the princess said that there were so many strange people over there, leaving only Wu Chengji, Sun Naen and Quan Nara, and the others were in Luoyang."

"Well, take it all with you." Xu Huabiao nodded, "This time, there may be a chance for the Shenji Battalion to fight." ”

"Oh, then I'll get them all armed?"

"Well, you go and arrange it, tomorrow we will leave for Hongnong."

"Good...... Well, this ......" Lin Yun'er shook the glass ball in her hand.

"You can take it and play with it!" Xu Huabiao smiled, "I also have to go and tell Yun Xi, she will give birth in a month or two, I will leave at this time...... I'm afraid that she is in a bad mood, so I have to go to appease her. ”

“…… Well, let's go, I'll go and tidy up the Shenji Camp, Childe, you go to find Yunxi, right? ”

"Okay."

Xu Huabiao nodded and followed Lin Yun'er out of the underground laboratory.

Soon.

“…… Huh? What about adults? Let's go? ”

Carrying a large basket of materials, the researchers finally returned to the underground lab, only to find that the place was empty.

……
