Walking in the underground of the Imperial City, Yang Guang appreciated the underground palace that almost hollowed out the imperial city and the imperial city from a bystander's point of view. This is a three-dimensional city. The imperial palaces opened to Yang Guang's organization are like castles in the air suspended on the ground. Except for the specially reinforced foundation, almost all of them are occupied by the city.

Using the world's superb craftsmanship skills and superb skills in mechanisms, Yang Guang drove the demons he controlled to almost empty the palace city and the imperial city.

The cornice attic is located on the ground and connected by bridges and cableways. The ground is hollowed out. On the basis of retaining the magnificent beauty of the imperial city and the beautiful scenery of the garden, it hollows out the underground and is reinforced by the mechanism steel structure to build a hollowed out underground city. A large number of craftsmen and craftsmen recruited live and work here, creating a holy land for Yang Guang's mechanism art.

"The skill of the mechanism craftsman in the Sui Dynasty is superb. Whether it is Yu Wenzhi and the Linjiang ten palaces built for me, or the Yang Gong treasure house built by Lu Miaozi for Yang Su, it is an amazing miracle in this era when the scientific understanding is not developed, not to mention the thirty foot high walls of Luoyang and Daxing City, the masters of mechanism skills!"

"It's nothing to build a 100 meter high wall for the two capitals, which is equivalent to the 33 story high wall in 1500 years. I just dug a canal of more than 2700 kilometers, and the world was full of flames? How unreasonable!"

Listening to Yang Guang's complaint, Huang Chang can only smile bitterly: "Your Majesty, the Beijing Hangzhou canal is beneficial for thousands of years, runs through the north and south, is the foundation of China's great unification, and will prosper for 500 years, is the foundation of the prosperity of the South and the Ou of the unification of the north."

Yang Guang looked at him with his head tilted. "Don't I know this? I still need you from the Song Dynasty to tell me?"

Huang Chang could only continue to smile bitterly: "After all, in the world where I was born, I didn't have such a high skill in mechanism in Sui and Tang Dynasties. I heard that the war god Hall of Jingyan palace is a masterpiece of mechanism learning in the world. It's mysterious and strange. I can't even think of it! Therefore, the old theory of Sui and Tang Dynasties in my hometown may not be the same as this world. The reason why the history is similar... Maybe it's the will of heaven!"

"The world that can change eyeballs at will may not be normal!" Yang Guang said faintly.

Huang shang will be shocked by this, but Yang Guang won't. He is a person who has seen the world. Although he hasn't witnessed the legendary Jingyan palace moving along the track of the stars in the sky, he has the construction methods of star sized cosmic warships in his memory. Naturally, he doesn't care about these, but the main consciousness vaguely warns him that he can't directly apply the technology in his memory.

It's like hiding from the peep of something.

Therefore, we have to combine with the local mechanisms of the world to realize some of our ideas.

Huang Chang led the way in front and said: "in recent years, the Sui Dynasty has built many palaces, dug canals for more than ten years, and made siege mechanisms several times. Therefore, there are many great masters skilled in mechanism skills in the imperial court. In addition, under the erosion of the soul of his Majesty's demons, he has reshaped himself for a large number of prisoners and rebel prisoners, and reborn into a person proficient in science."

"With the cooperation of the two, the study of mechanism has been greatly expanded. Smelting, casting, construction, power, machinery, chemistry, physics and engineering have entered the country rapidly. Only electric power has failed to meet the requirements."

"If we catch another batch of rebels, nothing in the world is enough, just there are many people!"

"Even if the last Wagang rebel is electrocuted, you should complete the motor core and power system!" Yang Guang ordered.

"Now we can use Hydropower to generate electricity and drive a five horsepower motor, but it will take several years to improve the combination with mechanism technology. The power scale is enough for craftsmen to manufacture and supervise small-scale electrolytic aluminum, and the smelting of steel is on the right track..." Huang Chang quickly reported.

Yang Guang interrupted him and said, "to control the input speed of science, we should mainly help the mechanism technology of the world, summarize the principles and provide ideas. We should never lead its development, so as not to attract the attention of the 'Lord God' and damage the great event of the Buddha!"

"Yes! So I have been afraid to forge firearms on a large scale!" Huang Chang reported.

Yang Guang came to a complex attic. The security here is very strict. There are eunuchs from East and West factories everywhere, and a bunch of demonized twelve guards guarding here. However, as Yang Guang, he can easily enter.

Inside is an ordinary forging and processing room. Perhaps there are many amazing organs and machinery in other places, but it is really a normal scene here. There are some different things only on a high platform in the center of the side hall.

It was a huge Arm Armor twice the size of an ordinary person's arm. It was composed of countless parts and machinery. It was red with blood and emitted an amazing heat. Yang Guang touched the surface of the arm armor as if the heat of melting gold and eroding iron was isolated by the magic gas, but it was enough for him to feel the lethality.

Yang Guang stuffed his right arm into the arm armor and felt the only warm temperature inside and the mechanical structure very close to the muscle. He approached and looked at the mechanism art. The harmonious components form a perfect whole, transport the Qi, and control the hot force on the surface of the arm armor to mix into a hot Qi.

"Magic weapon!" Yang Guang sighed.

"Superb workmanship!" he raised his right hand and felt the smooth movement of the arm armor.

"It's good to have such achievements in the subject of integrating real Qi and mechanism!" Yang Guang stretched out his right arm and poured magic Qi into his right hand. The terrible erosion force immediately entangled the arm armor.

"If there is a hot internal expert with genuine Qi attribute, hold this magic weapon..." Yang Guang glanced at Huang Shang, and he immediately announced the name of the weapon: "iron smelter!"

"Hmm! Holding this iron smelter... Can immediately defeat the top experts. The evil king and empress Yin are all right. Although they can't win, it's hard to lose! If you create another martial arts cooperation, it's not difficult to establish a school. But..." Yang Guang suddenly said sharply: "do I want these wastes?"

With a slight fist clenched, the arm armor made of precious alloy sounded broken from the palm of his hand. Under Yang Guang's grip, a powerful magic weapon was broken into countless pieces.

"Get your ideas out of the weapon! I don't need strong power. There is no power in the world that can be stronger than me! Use the way of mechanism to explore the wonders of heaven and earth and realize all kinds of true Qi. What you can't do is the goal you want to achieve, such as flying, controlling water and fire, and resisting a thousand forces."

"I'd rather you gave me a strange thing with a fuel injection pipe so that people can manipulate the flame with true Qi than you take out such a fool." Yang Guang said coldly.
