"Congratulations to the host, the system upgrade was successful!"

A prompt sound pulled Luo Chen back from deep thoughts, and his whole body was filled with excitement!

"System, what changes will happen to this upgrade?"

"This system has been fully upgraded and has entered the 3.0 era. The functions and architecture have undergone tremendous changes!"

"First of all, from the summoning system to the sign-in system, it is divided into daily signs, monthly signs, and annual signs according to the level. Daily signs can sign magical weapons, sweat-blooded BMWs and some rare treasures!"

"And monthly signing is possible to sign out civil and military officials and generals who have been in China for 5,000 years, so that they can serve as the host!"

"As for the annual signing, it is even more precious. Only the annual signing can be signed out on January 1st every year, and a pre-Qin figure can be randomly signed out!"

"At the same time, the lottery system and system mall have also been innovated, and the system functions have been increased!"

After listening to the system's introduction, Luo Chen's eyes were full of surprise: "Change the summoning system to a sign-in system?"

"Dog system, are you right?"

"This system has new functions, a technology tree!"

"The host can conduct scientific and technological research and development through the science and technology tree, accelerate the historical process, and promote industrial development!"

"What!"

Luo Chen's eyes were full of surprise. If he was not mistaken, this should be the biggest difference in this update!

"System, check the details of the technology tree!"

As soon as he finished speaking, a three-dimensional picture full of science fiction appeared in front of him. From bottom to top, the dark icons really dazzled Luo Chen!

"System, how can this technology tree be lit up!"

"There are three ways to light up the technology tree!"

"The most direct thing is to use points. The points required by each technology are different!"

"The host can also randomly light up the technology tree if it achieves some battle victories or changes the historical process!"

"The host can also light up the science and technology tree by establishing a scientific research institute and obtaining scientific research value!"

Luo Chen's eyes were full of surprises, and this system upgrade could be said to be just right!

Now Luo Chen’s biggest need is not civil officials and military generals. The five generals of the Dragon Army are in charge, including Dian Wei Guanyu, Yuwen Chengdu, Ma Chao, Cheng Yaojin, etc.!

The literature includes Di Renjie, Zhuge Liang, Guo Jia, Xun Yu and others, which can be said to have gathered all the heroes in one day!

However, the innovation of technology has almost reached a bottleneck!

It is a dream for Luo Chen to achieve industrialization by relying on his own strength. Even if he has a system, it will not work for thirty or fifty years!

However, the driving effect of this technology tree is so terrifying!

As long as the technology tree is illuminated, it will be incalculable to promote Daxia's technological innovation!

"System, light up the Zhuge Crossbow!"

"Does the host use 50,000 points to light up the Zhuge Crossbow?"

"yes!"

"Congratulations to the host for obtaining the drawings for making Zhuge Crossbow!"

Luo Chen took out the drawings of the Zhuge crossbow directly from the system space, was stunned for a moment, and suddenly asked: "System, can Zhuge Liang make the Zhuge crossbow method?"

"meeting!"

"Wori!"

Luo Chen's eyes were full of anger, and he felt like he was being put on.

"System, you're cheating me!"

"I don't want it, refund the money!"

"This system does not support the return function!"

"Wori!"

Luo Chen couldn't help but swear, "Come here!"

"exist!"

Zheng He jogged in all the way, looked at Luo Chen's deep face, and did not dare to ask too much, and saluted respectfully!

"His Majesty!"

"Talk this drawing to Lin Chao and tell him that if you cannot make Zhuge Lianbi for me within one day, I will punish him with a salary!"

"yes!"

"etc!"

Luo Chen suddenly waved his hand to stop him and said softly: "Come Zhuge Liang for me first!"

"yes!"

Zheng He looked at Luo Chen with a strange expression and walked out quickly.

Not long after, Zhuge Liang hurried over: "Your Majesty!"

"It's just right!" Luo Chen asked impatiently: "Kong Ming, I want to ask you, do you know how to make crossbows?"

"Serial crossbow?"

Zhuge Liang hesitated for a moment and nodded slightly: "I'm thinking about it!"

"Um!"

"Look at this drawing!"

Zhuge Liang took it with a puzzled look and looked at it, his eyes full of surprise: "This..."

"Your Majesty! Where does this drawing come from?"

Luo Chen smiled and said, "I have nothing to do and think about it myself."

"Your Majesty, I admire you!"

"With this crossbow, our army's combat power will be greatly improved!"

Luo Chen sighed and said softly: "It's just that the production of this crossbow is too cumbersome. It seems that it is not that easy to mass-produce it in a short period of time!"

Zhuge Liang also nodded slightly and said with a smile: "Your Majesty, I'm afraid that the envoys from all countries will come here for another purpose, right?"

Luo Chen nodded with a smile, "No, it seems to be for the martial arts conference!"

"Martial Arts Conference?"

Zhuge Liang was quite surprised: "I didn't expect this..."

"Does they want to change the martial arts conference to be held in my Daxia?"

"Um?"

A trace of surprise flashed in Luo Chen's eyes and he said softly: "Is it Wang Sen telling you?"

"Where is this saying?"

Luo Chen was stunned for a moment and smiled and said, "I just talked about this with the Minister of Rites, but I didn't expect you to guess it!"

Zhuge Liang smiled and said, "This matter is not difficult to guess!"

"Your Majesty, this may not be a bad thing for us!"

“Why?”

"They just want to open the gates of my Daxia. But now my Daxia has the Jinyiwei White-Yiwei guards to monitor the world, and there are many masters and masters in charge. They want to turn the world upside down, and they are afraid they are delusions!"

Luo Chen nodded slightly and said softly: "After that being said, now that I am a war in Daxia, if a large number of people rashly let a large number of people enter the country, both the Jinyiwei and the local area will bring huge pressure!"

Zhuge Liang nodded, this is undeniable!

"Let me do not show up tomorrow, and you will hold a banquet in the world and entertain envoys from all over the world!"

Zhuge Liang's expression suddenly changed slightly: "Your Majesty, is this a bit inappropriate?"

Luo Chen smiled faintly and said softly: "It's okay, Qin is my enemy, Western Chu, Jingguo's attitude has nothing to do with me, and Da Zhou will not mind, so he has to do with Bei Cang, hum!"

"They have known about the plans of several countries this time, but they have not communicated with us!"

Luo Chen was also quite angry, and there was no need to accommodate the envoys of several countries!

"His Majesty!"

Zheng He walked in slowly and said softly: "Your Majesty, the Ministry of Rites sends a message, Ning Gong's funeral is ready!"

"According to the constitution, we will be buried tomorrow!"

Luo Chen nodded slightly: "I will attend Ning Gong's funeral tomorrow!"

"ah?"

Zheng He was stunned: "Your Majesty, are you saying that you want to attend Ning Gong's wedding in person?"

"good!"

Zhuge Liang was stunned for a moment, his eyes flashed: "Your Majesty..."
