With the support of the energy ore in the treasury and the high-grade Demonic Beast crystal nucleus, nine spiritual energy sources were soon opened.

Guarded by a team of Imperial Guards in shifts day and night, coupled with the defensive capabilities of the formation itself, the safety of the Aura Sources can be guaranteed.

Bai Qi, Zhao Yun, Su Long, Lu Bu, Hua Mulan and other legendary realm generals took a large number of original Nirvana Realm masters and Enlightenment Realm masters in the imperial capital to the source of spiritual energy to cultivate, striving to break through as soon as possible and complete the new Nirvana Realm Nine Turns.

A spiritual energy source is very large, almost able to accommodate tens of thousands of people, and it is located in the nine large school grounds of the imperial capital. A source of spiritual energy can accommodate the cultivation of all high-level martial artists, and the waterfall-like spiritual energy vortex allows the martial artists to bathe in it, and their strength increases rapidly.

And the other eight spiritual energy sources can't be empty, right?

Su Yu simply arranged for the soldiers of the core legion of the Yanhuang Legion, the Women's Army, the Repeater Army, the Trap Camp, the Tiger Army, the Bingzhou Wolf Cavalry, the Black Jade Cavalry and other soldiers to go to the remaining eight spiritual energy sources to cultivate, and arrange the soldiers to cultivate in batches.

The existence of the source of spiritual energy is undoubtedly a blessing for the soldiers and high-ranking martial artists of the Yanhuang Empire, and the thick spiritual energy makes their cultivation speed extremely fast, including the strength of the soldiers in the army.

In the next week, Su Yu, who has more than 30 million points of people's energy, lit up all the core technologies of the electrical era on the science and technology tree, and by the way, also lit up the core technology of the information age [computer and communication], spending 20 million points of people's energy.

Including [aviation technology and principles], [electrical technology], [artificial satellite technology], [electromagnetic technology] and a series of more important scientific and technological data that are difficult to develop in the short term of the scientific research institute have been lit up by Su Yu, and these scientific and technological technologies have been handed over to the scientific research institute.

Although the scientific research institute has not yet reached that height, Su Yu has already prepared their scientific and technological research and development route for a long time in advance.

In addition, Su Yu also selected some branches of gunpowder technology and some scientific weapon technologies such as electronic weapons, molecular weapons, nuclear bombs, neutron bombs, and hydrogen bombs to light up with popular energy.

As for the remaining scientific weapons, Su Yu directly exchanged them for detailed data theory books in the Wanjie System Mall, and stuffed them into the scientific research institute along with all the design drawings.

The talents I have spent so much time cultivating are now the time to exert themselves!

The sum of these technologies made Su Yu spend a full 30 million people's energy.

It can be said that all the people's energy rewards that Su Yu received were invested in the scientific research institute, and the scientific research institute has been operating extremely fast under the command of Zhuge Liang.

It can be said that so far, the scientific research institute has become the core building of the Yanhuang Empire, it is located next to the imperial palace, and it is the place where all the outstanding students, craftsmen and alchemists of the entire Yanhuang Empire are most eager to go.

Only those who have learned are qualified to work in the scientific research institute, which is the highest honor in the hearts of the craftsmen and students of the Yanhuang Empire! The entire seven major counties of the Yanhuang Empire plus all the schools, craftsmen, and alchemists in the Great Demon County have worked hard, hoping that they can show excellent results, enter the university scholar's mansion, and then enter the scientific research institute.

As for the title of the craftsman......

It's a pity that the people in the scientific research institute have not yet developed a more powerful energy bomb, so the title of craftsman promised by the emperor can only be postponed.

It is worth mentioning that due to the importance of the scientific research institute, Su Yu specially approved all the energy ores and demonic beast crystal nuclei in the treasury to be invested in the Yanhuang Scientific Research Institute, and handed over the construction and operation rights of the national factory to the Yanhuang Scientific Research Institute.

The Yanhuang Research Institute is now coordinating all the research and operation of energy ores, including the steam engines and production lines that are sold and eliminated by the Yanhuang Alliance, and all of them are handed over to the research institute.

Even the ogre laborers and the laborers gifted by the various tribes were sent to the orc empire to mine.

According to Zhuge Liang's instructions, this group of laborers can only be free if they mine to a certain amount! For the sake of freedom, the work mood in the laborers is extremely high, and there is no need to supervise the work at all, one by one, day and night mining!

Half a month later, the alien nations within the Yanhuang Alliance all possessed steam engines and production lines, and these new technological items brought rapid changes to their racial countries.

The powerful productive forces of the countries and races up and down the Yanhuang Alliance burst out, which shocked the entire Eastern Continent!

Especially the Orc Empire, in just half a month, it has regained its vitality and prepared the domestic army, except for the smaller population, the recovery speed of all walks of life is extremely fast!

This made the races of the Night Alliance stunned!

"What happened in the Orc Empire, and why did they recover so quickly?"

"Didn't the Emperor say that the Orc Empire would not be able to recover within a hundred years? I heard that they had already re-formed the Orc Legion three days ago!"

"Damn! How did they do it! No matter how terrifying the orc's reproductive ability is, these millions of orc legions can be equipped with weapons, armor, and arrows? I don't believe it!"

"I don't believe it either, but in fact, the Orc Empire has already completed the formation of a new army! And I heard that Andrew Beast Lord is still preparing to form a new Beamon Legion, and even a series of equipment such as Beamon Knight and Giant Saddle are ready, just waiting to select Beamon Giant Beasts from Beamon Sacred Mountain!"

"Oh my God! Even if a Beamon knight is excellent, if you want to control the Beamon Giant Beast well, you can't do without the Giant Saddle! But a pair of Beamon Giant Beast's giant saddles add up to at least hundreds of pounds, and the structure is extremely complex, if you want to build a set, it will take at least a month!"

"And there are at least a hundred Beamon Giant Beast Legion in the Beamon Giant Beast Legion to be called a legion, they have so many Beamon Knights, I believe, but where did they come from so many giant saddles! The number of craftsmen in the Orc Empire is notoriously rare!"

In the court of the Night Empire, the pot has already exploded. Everyone couldn't accept this fact, but the Yanhuang Alliance told them with actions that the Yanhuang Alliance was becoming unstoppably stronger!

The civil and military officials exchanged their heads one after another, and in the face of the changes in the countries of the Yanhuang Alliance, they all felt extremely frightened.

Originally, the Yanhuang Empire was already very powerful, but now even the allies with Su Yu have become stronger, and their development speed has far surpassed that of the Dark Night Alliance!

If they are allowed to develop like this, within fifty years, the Dark Night Alliance will inevitably lag behind the Yanhuang Empire, and the Dark Night Alliance will definitely suffer a big loss in the confrontation between the two major forces in the future!

The people in the Night Alliance are like ants on a hot pan, everyone is extremely anxious.

We must find a way to know why the Yanhuang Alliance is so powerful! When necessary, we will not hesitate to use force! Even if we start a war, we must find out the reason!

The Night Emperor ordered on the spot: "Investigate! Strictly investigate the widow to the end! You must know what is going on inside the Orc Empire and the other principalities of the Yanhuang Alliance! Why do they have such a strong development force!"

The intelligence agencies of the entire Night Alliance are operating frantically, and the Orc Empire can still resist the spying of the Night Alliance spies, but some of the principality races in the Yanhuang Alliance do not have this strength.

Soon, the Night Emperor learned the inside story.

It turns out that the duchy races of the Yanhuang Alliance have two things called "steam engine" and "production line"!

Just when the Night Emperor thought that he had discovered the "great secret" of the Yanhuang Alliance, he had not yet figured out the role of the "steam engine" and the "production line".

A sudden storm of public opinion suddenly erupted within the Dark Night Alliance.

The second more.
