Sending Yuan Wenxin away, Lan Jing returned to the study and continued to draw until the end of the day.

She had just put down her pen and stretched her waist when there was a sharp knock at the door.

Lan Jing frowned, wondering in his heart, who would knock on the door at this point in time? Could something have happened?

Thinking of this, she quickly stood up and asked, "Who's outside?"

"Shizi, his subordinate Zhang Biao, has something important to return. ”

Lan Jing walked over quickly to open the door, only to see Zhang Biao eagerly arching his hands waiting for her response, she took a deep breath, "Say, what's wrong?"

"When I returned to Shizi, I just received news that the troops led by General Qu had been captured by the Tartars, and the grain and grass had also been taken away. Zhang Biao responded.

Lan Jing's face froze, "How could such a thing happen?" Qu Chongyi brought all the elite soldiers. ”

"Hui Shizi, my subordinates can't figure it out, it stands to reason that it is impossible for the Tartars to have such a large army sneak into our Daqing Kingdom. Zhang Biao's face also showed solemnity as he spoke, "If they have food and grass, then they will definitely attack our Mobei military camp again soon." ”

Lan Jing nodded, "If this continues, my weapon has not been made yet, and the person has been destroyed." ”

The two were silent for a quarter of an hour, and after Zhang Biao looked at Lan Jing twice, he asked, "Shizi, what should we do now?"

Lan Jing thought for a moment and said, "Tell Chen Ziyi the news, let him strengthen his precautions, and then inform Grandpa Yang that he will start work overnight, and I will go over with the artwork now." ”

"Yes, my subordinates obey. Zhang Biao turned around and left.

Lan Jing hurried to the iron factory with the drawings, and unlike the last desertion, the workers were sweating in and out shirtless, carrying things.

The fox guarding the iron factory saw Lan Jing and hurriedly greeted him, "My lord, is the news you just sent true?"

Lan Jing said as he walked inside, "What news are you talking about?"

The fox approached Lan Jing and whispered, "It's Qu Chongyi who was intercepted...".

Lan Jing turned sideways to face him, "Regardless of whether the news is true or not, it's good to prepare as soon as possible..."

Before her words fell, Yang Tie strode over, "Xiao Jing, you're here, what's the picture?"

"Here, this diagram is just a preliminary idea, and everyone has worked hard to make it in the past few days. Lan Jing handed the artwork to Yang Tie.

Yang Tieru got the treasure, looked at it carefully, and then pointed to the picture and said, "Here, is this really feasible?"

Lan Jing didn't dare to pack the ticket, so he had to say, "You'll know if you do it." ”

Her words were understood by Yang Tie as sure that it was okay, so she immediately started to do it.

………

Three days later, a series of weapons drawn by Lan Jing from memory were made.

Looking at the formed weapons, not to mention the workers, even Chen Ziyi was amazed, and excitedly pointed at them and asked, "How do you use these?"

Lan Jing stepped forward with a smile and stood next to the weapon, and said, "This is the Zhuge Repeater, which has a long range and great power, and is several times better than a bow and arrow." ”

After introducing the Zhuge crossbow, he took a few more steps, "This catapult can throw stones into the enemy's army, but we don't throw stones, but instead of throwing stones, we can use spirits instead, spirits can make fire, and with rockets, it can have an unexpected harvest." ”

Speaking of this, Lan Jing couldn't help but sigh and said: "I want to drop a bomb, but unfortunately I can't remember the formula, I only remember a golden ratio of 1:2:3, if I make a bomb, they dare to be fierce again, I will throw a few more into their army, to ensure that there will be a time for him to cry!"

"What is that?" After hearing this, everyone was excited again, listening to what the adults said, it seemed that the thing called the bomb was very powerful!

Lan Jing came back to his senses, "Oh, it's nothing, you don't understand it, continue to tell you about this weapon." ”

Everyone was slightly disappointed, but if the adults didn't say anything, they didn't dare to ask again.

Lan Jing moved two more steps, "This is a cloud supporter, okay, I admit, this is an ordinary support, the main function is to give the Tartars a chance to attack the city if they are not defeated, then they can use this to support the ladder to climb the clouds." ”

"And this, this is an armored vehicle, and now you can't see the power, but when you get to the battlefield, you will find that it is the natural enemy of the cavalry. This empty space can accommodate people, and the wheel below can be pushed directly. ”

"Look at the following, this gear will leave gaps in the inside and bottom of the car when the car moves slowly, and with a special chopping knife, it can cut the horse's feet in the enemy's formation, and the upper two sides also leave gaps, and you can use a spear to stab the enemy. ”

After Lan Jing finished speaking, everyone's eyes widened in shock, and it took a while for someone to take a big breath, and some people began to exclaim: "This is amazing, why didn't we think of it before?"

"Can you think of it in your brain? ”

"Hehe, I know I'm stupid..."

Lan Jing shook his head and smiled, "Actually, this is not what I think, I am as stupid as you, this is what others think." ”

No one believed Lan Jing's words, and they all thought she was modest, but they wouldn't argue with her about it.

Chen Ziyi touched this and that, and nodded with satisfaction, "Xiao Jing, I have taken these weapons away now, you urge them to do some more, especially this armored car and Zhuge Repeater." ”

"I'll go with you, just look at Grandpa Yang here. Lan Jing said.

Chen Ziyi shook her head, "Now the camping place outside the city is often sneak attacked, although it is not an official war, but it is full of dangers, you aunt..."

Hearing this, Lan Jing hurriedly interrupted him, "As a prisoner, this prince has the responsibility and obligation to fight against the Tartars with everyone. ”

Yang Ji glanced at Chen Ziyi and said, "Xiaojing, you better stay, here, there are still many places that are not particularly clear, you are not here, you are not sure." ”

"Yes, yes, you won't have a backbone as soon as you're gone. The fox said.

Lan Jing turned his head to look at them and smiled slightly, "I believe Grandpa Yang, there is absolutely no problem with him." ”

Yang Tie happened to come over from inside, and when he heard this, he said, "Xiao Jing is right, don't worry, leave it to me." ”

Yang Ji sighed, he knew that his father was a hindrance.

Chen Ziyi had no choice but to say: "It's okay to go, but you have to let someone follow you to protect you." ”

Lan Jing waved his hand, "Let's talk about it then, I have a hunch that there will be a fierce battle soon." ”

As soon as her words fell, Wang Qiang strode in, he handed a note to Lan Jing and said, "Shizi, this is sent by Tartar." ”

Hearing this, Lan Jing took the note, and only one sentence was written on it, "Tomorrow at noon, prepare a hundred stones of grain and grass for your general." ”

"A hundred stones, he won't rob it..."Yang Ji said angrily.

Lan Jing gently hooked the corners of his mouth and gave the note back to Wang Qiang, "Six tons of grain, they think it's beautiful." When you go back, just say that our generals are willing to sacrifice their lives for Daqing, and let them kill or chop at will. ”[.]
