By the way, Zhao Feng hurried to the blacksmith shop, and Master Wang was teaching the blacksmiths a class with the made mold.

"Master Wang, stop for a while, I'll have something to ask you for trouble!" Zhao Feng said.

Master Wang immediately put down what he was doing: "Lord, I wonder what's wrong?"

"That's right, I suddenly thought, can we design the tip of the gun and arrow like this?" Zhao Feng began to draw on the paper.

I saw that Zhao Feng saw the tip of the gun with a blood groove! This tip of the gun was somewhat similar to the triangular military spear of later generations. This is another suggestion that Qing'er gave Zhao Feng. In addition to bleeding, the blood groove on the gun tip has a more important role, which is to facilitate the extraction of the gun tip!

After the triangular spear tip pierces into the human body, blood will flow out with the blood groove, but the muscles will not clamp the spear tip tightly because of contraction! I believe that both ancient and modern people hope to save some effort, right?

Moreover, what's even more amazing is that the wounds pierced by the tip of this gun are triangular blood holes, and the flesh and blood near the wound cannot be squeezed to achieve the effect of stopping bleeding! Moreover, the wounds caused by the tip of this gun are all ruptured by blood vessels, so what's the point of you just suturing the surface?

Such wounds can almost be said to be fatal in the late Han Dynasty, where medical technology is still very poor!

"Sir, it's too hard to build the gun tip you draw." Master Wang said, "It can be basically made, but some details cannot be taken into account."

"Let's do this, first create such a gun tip as much as possible, and take the finished product to me first, and then I will decide your next step." Zhao Feng said.

"Yes, lord!" Master Wang bowed.

"By the way, have Yun Chang and Yide's weapons been built?" Zhao Fengfu asked again.

"I have built it overnight and it will be completed in the next few days!" Master Wang was also very excited when he mentioned these two weapons. Which blacksmith doesn't want to create a magic weapon with his own hands? According to Zhao Feng's design, once these two weapons are built, they will be peerless magic weapons!

"Well, you can have snacks! Don't make any mistakes!" Zhao Feng said.

"Yes! I must do my best!" said Master Wang.

"Okay, then I'll leave! Find me any difficulties whenever you have!" Zhao Feng strode out of the blacksmith shop.

...

"Xue'er, how do you feel today?" Zhao Feng asked softly after feeding the chicken soup.

"It's much better. If Brother Feng takes care of me like this, Xue'er doesn't know what else to say." Bian Xue said with tears in her eyes.

"It's all my women, why are you talking about these?" Zhao Feng pinched Bian Xue's face and said, "Just make good compensation for me in the future!"

"Yes!" Bian Xue nodded with a red face.

"Master!" At this time, the butler knocked on the door.

"Hmm? What's the matter?" Zhao Feng asked.

"There is a man outside the door who calls himself Nanhua and wants to see his lord!" said the housekeeper.

"What? You said Nanhua?" Zhao Feng said in surprise, "Come in quickly, no, I'll go to greet you in person! Xueer, you lie down first."

"Yes." Bian Xue nodded obediently.

Zhao Feng strode out of the room.

Speaking of Nanhua, he was one of the three immortals at the end of the Han Dynasty and the most powerful of the three immortals. It can also be said to be the master of Zhang Jiao, the leader of the Yellow Turban Rebellion.

As soon as he left the door, Zhao Feng saw an old man with a blue-eyed and a quinoa stick in his hand.

"I don't know if the old immortal is coming, and I'm sorry to welcome you. I hope you can forgive me!" Zhao Feng bowed respectfully.

"Hehe, Prefect Zhao is polite!" Nanhua said with a smile.

"I'll ask the old immortal to give me some advice!" Zhao Feng said respectfully.

"It's easy to say!" Nanhua laughed and walked into the prefect's mansion.

"I wonder what is important about the old fairy coming to find Feng?" After entering the living room, the guest and hosted guests sat down, Zhao Feng asked first.

"Haha, I observed the celestial phenomena at night and discovered a demon star and four emperor stars." Nan Hua said with a smile.

"Oh? What does that old immortal mean?" Zhao Feng said calmly.

"The four emperor stars, one is in Jiujiang, the second is in Luoyang, and the third is in Zhuojun. However, these three are dim and dull compared to the fourth one." Nanhua said.

"Oh? Where is the fourth one the old immortal refers to?" Zhao Feng's tone was still very calm, but at this time he was extremely surprised. Sun Jian was in Jiujiang, Cao Cao was in Luoyang, and Liu Bei was in Zhuo County! The heads of the three immortals at the end of the Han Dynasty seemed to be worthy of their reputation!

"Hehe, it's far away in the sky, close in front of you!" Nanhua stared at Zhao Feng with a smile.

"Is the old immortal talking about Zihu?" Zhao Feng pointed at him and asked in confusion.

"That's right!" Nanhua said with a smile, "Zihu is the most shining one among the Four Emperors Stars!"

"Really?" Zhao Feng frowned slightly.

"I am not surprised by favors and disgraces! I am indeed a hero, and the old Taoist admires it!" Nan Hua said.

"The old fairy is joking." Zhao Feng waved his hand, "I don't know if the old fairy is coming to Liaodong this time..."

"First, let's see what kind of person the leader of these four emperor stars is, and secondly, it's for my incompetent apprentice!" Nan Hua said.

"Advisor?" Zhao Feng was puzzled. Could it be that he refers to Zhang Jiao?

"Hey! As you think, my unworthy disciple is Zhang Jiao!" Nanhua seemed to see through Zhao Feng's thoughts, "At that time, I gave him three volumes of "The Strategy of Peace" to make him use his own behalf to save the world, and he? Hey! What is the dead of heaven? Huang Tian should stand up! It's simply confusing the world!"

"Haha, Master Zhang also wants to transform into the world, but the way he used was wrong." Zhao Feng said with a smile.

"Zihu, don't underestimate the power of writing Taiping! That's not just a book, it's all-encompassing. If you practice properly, you can reach the sky and the earth!"

"So powerful?" Zhao Feng asked, "Then isn't Zhang Jiao invincible now?"

"It's not entirely true. I still have three books. Now I give it to Zihu. I hope Zihu will study it well and will definitely crack the "Balance Essence"!" After that, Nanhua took out three books from his sleeve, and saw that they said "Sky Escape", "Earth Escape" and "Man Escape" respectively!

"This is? "Dunjia Tianshu"? But wasn't this written by Zuo Ci?" Zhao Fengdao.

"Oh? Zihu actually knows this book? But what Zihu said, my junior brother Yuan Fang? Why is this book written by him?" Nan Hua looked at Zhao Feng in confusion.

"This..." Zhao Feng scratched his head awkwardly, unable to say it and why, it can't be said that it was said in "Romance of the Three Kingdoms", right?

"Haha, since Zihu doesn't say it, then the old Taoist will not ask. However, Zihu, you must remember that you are the biggest variable between heaven and earth, and you must make good use of these three volumes of heavenly books! The old Taoist said goodbye!" After that, Nanhua rose directly in front of Zhao Feng's eyes and flew towards the sky.

"Is this old man really a god?" Zhao Feng murmured.

"Of course, Nanhua is of course an immortal. In history, it was precisely because he gave these three volumes of heavenly books to Cao Cao that Cao Wei won the world. However, Cao Cao's descendants were not successful, so the heavenly books were abandoned, so the Sima family was able to usurp power successfully! Otherwise, what would happen if the Sima family had a smart plan?" Qing'er said.

"So that's it! According to what you said, can you still know the master of this "Dunjia Tianshu" by yourself?" Zhao Feng asked.

"Of course, "Dunjia Tian Shu" is the legendary wordless heavenly book. Only by being recognized by the heavenly book can you see the words on it. Big idiot, your luck is really great. The reason why Nanhua did not give the heavenly book to Cao Cao but gave it to you was the result of the heavenly book's own choice!" Qing'er said.

"Hehe, hehe!" Zhao Feng couldn't help but smile foolishly.

"Why are you smirking? Hurry up and study "Dunjia Tianshu"! I can save some trouble in the future!" Qing'er rolled her eyes and said.

"Huh?" Zhao Feng seemed to hear Qing'er's voiceover. It seemed that his system was even better than "Dunjia Tianshu"!
Chapter completed!
