Unconsciously, Su Yu has changed from the exiled son to the king of a country.

The issues and positions that Su Yu needs to consider at present are no longer a matter of a county in Heishi County, nor a county in Beishan County.

He needs to think from the perspective of the entire Yanhuang Empire, and the most important thing for a country is undoubtedly the improvement of people's livelihood, economy, military and other aspects.

Especially in the Sifang Continent, where the status of the human race is low, Su Yu has more problems and scruples to consider.

"Knock knock. ”

Su Yu's fingers lightly clasped on the desk, and after a long time, he decided.

Upgrade your territory first!

Then use virtual buildings to improve and strengthen the development potential of the entire Yanhuang Empire.

Now that the army and generals are also sufficient, Su Yu is not in a hurry to continue to expand the army and summon new generals, and to improve as soon as possible and lay a solid foundation for development, which is a very important thing.

Running a country is like a strategy game played by Su Yu in the previous life, not only must be good at battles and situations, but also take into account its own development, and must not focus on one aspect and ignore the development of the empire as a whole.

However, it is much more difficult to run the Yanhuang Empire than to play games by himself in his previous life, and Su Yu at this time has no chance to delete the number and retrain, and he must be cautious in every step.

"System, I want to upgrade the territory level!"

Su Yu opened the system screen and said in a deep voice.

【Drip!Territory upgrade begins!】

The system emitted a series of sounds, and a faint light began to appear above the virtual territory and virtual buildings displayed on the screen, constantly flickering, and then the light expanded, filling the entire system screen.

In less than a stick of incense, Su Yu's people's energy has plummeted by one million, and the system has completed the territorial upgrade.

Congratulations to the host, the territory upgrade has been successful!The current host territory level is level 3. 】

The system's prompt sounds.

Su Yu looked at the scene on the system screen, and there was not much change, but the earthy yellow earth seemed to have become more spacious, and the virtual buildings did not increase or change.

Su Yu opened the attributes of the system territory.

Aside from the requirement to upgrade the next-level territory that requires 10 million people's energy, there are no other obvious changes.

Just when Su Yu frowned, the next wave of prompts of the system sounded continuously.

[Drop!Congratulations to the host, successfully upgraded the territory!The system Wanjie Mall opens three-level permissions!]

[Congratulations to the host, successfully upgrade the territory!The system opens the upper limit of the three-level upgrade of virtual buildings!]

[Drop!Congratulations to the host, successfully upgrade the territory!The system rewards the number of times you use the lord's altar once!]

[Drop!Congratulations to the host, successfully upgrade the territory!The system rewards the number of draws for using the colorful roulette once!]

Congratulations to the host, successfully upgraded the territory!The system opens the virtual building technology tree. 】

......

A series of system prompts made Su Yu a little confused.

"There are so many benefits just to a level?"

Su Yu touched his chin, he guessed that it might be because the upgrade of the territory to level three was a watershed, because he had a hunch that after this upgrade, I am afraid that there will not be a large number of system rewards in the future.

But even so, Su Yu was still very happy, originally he just planned to upgrade a level to get some small system benefits, increase the authority of the Wanjie Mall, and expand the upgrade ceiling of the virtual building.

didn't expect the system to find out with a conscience and give Su Yu so many benefits.

Su Yu put aside the rewards he was familiar with for the time being, he opened the system screen and looked up the introduction of the latest virtual building [Technology Tree].

[Tech Tree]: The system virtual building can use the energy of the people to conduct research on any technology item has been improved, but all the technology options that are lit up can be converted into drawings and built using the virtual building blacksmith shop.

The technology tree is displayed in Su Yu's virtual territory in a very intuitive image, it is a lush tree that towers into the sky.

But as long as Su Yu clicks on this big tree with his finger, the system screen will automatically pop up a close-up of this big tree.

Su Yu took a closer look and found that this [Science and Technology Tree] seemed to have dense branches, but in fact it only had two branches, both of which had introductions, and they represented respectively: military science and technology, and people's livelihood technology.

Su Yu clicked on this to check, he clicked on the branches of military technology, there are dense and countless leaves on it, each leaf represents a military technology, as long as Su Yu lights up, the corresponding leaves will emit a brilliant and dazzling light.

In terms of military science and technology, it has the research and development of military technology of gunpowder, the research and development of ammunition improvement technology, the manufacturing and research and development of AK47, the core technology research and development of heavy sniper rifles, the manufacturing and research and development of bullet production lines, the manufacturing and research and development of self-propelled spider robots, the manufacturing and research and development of Mustang light tanks, the core technology research and development of artificial satellites, the core technology research and development of intercontinental missiles, the core technology research and development of humanoid weapons, and the core technology research and development of quantum weapons......

Dense, countless military scientific and technological weapons entered Su Yu's eyes, making his mouth grow bigger and bigger.

From the manufacturing and R&D technology of pistol bullets, to the R&D and manufacturing technology of spaceships, to the wormhole jump technology and plane shuttle technology...... Even the most critical thing was that Su Yu also saw a technique that made his pupils constrict suddenly.

[R&D of scientific and technological equipment and internal qi, true qi, and immortal qi fusion enhancement theory]!

Undoubtedly, this technology can combine scientific and technological equipment with the martial arts of the Four Continents to burst out with even more powerful power!

Is it that the bullet has a longer range?

Or are the missiles more powerful?

Or maybe a laser knife can slice through the void?

Rao is Su Yu has already exerted his greatest imagination, and he still feels that it is still not enough to keep up with the shock given by the system.

Su Yu endured his excitement, exited the military branch page, and clicked on the people's livelihood science and technology branch page.

It is still a dense number of scientific and technological projects, which almost blinded Su Yu's eyes: the manufacturing and research and development of steam engines, the utilization and research and development of circuits and resistors, the improvement and application of electric lights, the strengthening and improvement of electric tracks, the core construction technology of subways, the core technology of communication foundation, the research and development technology of 4G network, the application and research and development of 5G overclocking technology, the core research and development technology of mobile terminals, the core technology of the Internet, the people's livelihood application and manufacturing research and development of levitating magnetic vehicles......

Of course, there is still a big killer in people's livelihood technology!

[The combination and improvement of people's livelihood technology and internal qi, true qi, and immortal lifeforms]!

"This ...... This ....."

Su Yu opened his mouth and stammered, Rao is steady and wise, and at this time, he couldn't help but be stunned on the spot, his deep eyes were full of shock.

"Hey~!, you want me to cultivate a super futuristic power that integrates technology and martial arts!"

Su Yu couldn't help but gasp and muttered to himself.

Su Yu bit the tip of his tongue hard, and a tingling sensation came, and blood flowed out of the corner of Su Yu's mouth.

It hurts.

It's not a dream!

"The Great Killer... This is my great killer!"

Su Yu couldn't help but smile at the corner of his mouth, he couldn't imagine that after the territory was upgraded to level 3, he actually gave him such a big surprise!

If he had known that this would be the case, he should have not hesitated to upgrade the territory to level 3 in advance!

It's not too late!

As long as the technology on the technology tree is lit up, Su Yu can predict that the Yanhuang Empire will bloom in his hands with an extremely amazing dazzling brilliance! Not only the Yanhuang Empire, but even the entire human race will benefit from this!

At that time, the Eastern Continent, the Four Continents, and the Hundred Ethnic Groups will no longer be targets!

This world will never tolerate my grand plans!

"Hahahaha!"

Su Yu couldn't help laughing, his heart was excited and hot.

The technology of his previous life, everything he once longed for, everything he thought about day and night, could be realized again!

If it weren't for Su Yu himself, he wouldn't be able to experience this kind of excitement, remembrance, longing, excitement, and enthusiasm.
