The sun-shooting cannon lay silently on the plain, stretching from the west side of the imperial capital Sun City, all the way forward, and the length seemed endless.

At this time, a group of high-ranking officials and dignitaries of the empire were gathering at the starting position of this cannon.

Hundreds of lighting techniques reflect this piece as if it were daytime. The barrel, which is as high as 10 zhang in diameter, shone in the light, flashing with the cold light unique to metal!

"Your Majesty, please give the order to open fire. A minister stepped forward and said to a middle-aged man in plain clothes standing with his hands in his hands.

This man is not special in appearance, but his expression and demeanor all show a style of not being angry and arrogant.

He is Yu Wenhan, the emperor of the Rising Sun Empire, but he did not wear the emperor's dragon robe at this time, and he also stood with the ministers and craftsmen.

Yu Wenhan smiled and shook his head, and said to Shang Yi beside him: "The matter of firing the cannon is still done by the divine craftsmen of our empire." ”

Shang Yi was not polite, and only nodded to Yu Wenhan. Seeing that the expected time was about to arrive, his slender eyes firmly grasped the five hourglasses standing on the side.

He meditated in his heart: five, four, three, two, one.

"Fire!"

With a "hum" sound, everyone could sense that the aura that had already been stored at the base of the sun-shooting cannon burst out in an instant!

Ten breaths later, a hundred miles forward from the cannon base, a thick link that was specially thickened and reinforced, suddenly burst out with a dazzling orange light!

This proves that the cannonball has reached the first acceleration link, and this bright light is the scene of the explosion of energy, which is revealed by the leakage.

After another eight breaths, the two hundred miles away, the same knot-like reinforcement ring, burst out the same orange light again!

This second hundredth mile saves two breaths of time compared to the first hundred miles.

After about six breaths, the third reinforcement ring located three hundred miles away lit up!

The speed of the shells is getting faster and faster, and each time it passes through a reinforced link, it will receive an acceleration.

However, as the velocity of the shell increases, the acceleration becomes less and less.

For a full 1,300 miles, the thirteen acceleration rings were lit up in turn like marquees!

For the last hundred miles, judging by the interval between the flashes of the acceleration ring, it took four breaths for the shell to pass this distance.

"Bang!"

Accompanied by a sonic boom that resounded through the sky, a cannonball with a sharp front end and a narrow and thick rear end burst out of the barrel!

At the rear pedestal, Shang Yi ordered: "The second shell is in the chamber!"

A "boom" sounded, and the gun mount was opened from the tail. It's like opening a huge portal, revealing a black hole two feet in diameter.

In this way, the wall of this cannon barrel is also thick enough!

The outer diameter of a full ten zhang was originally only two zhang of holes inside.

But if it weren't for this thickness, I am afraid that it would not be able to withstand such ultra-high-speed shells!

Hundreds of people pushed a long cart, which carried the same cannonball as the previous one, two zhang square, and the length reached ten zhang!

"Hey, hey!"

Men were barearmed, drenched in sweat, nervously sliding the shell into the chamber.

"Boom!" the portal at the rear of the gun mount was securely closed.

Inside the spirit stone trough, the spirit stones that were originally stacked like mountains were quickly consumed like flowing water. The aura inside the gun mount began to gather rapidly.

"Shang Qing, which hero is in this second cannonball? I can't think of anyone else who can compare with that kid from the Tuoba family. Yuwen asked with a little curiosity.

Hearing this, the Fuguo Gong Tuoba Chengyu, who was standing on the side, immediately lowered his head. He was worried about his resentful look, and Yu Wenhan saw it.

If Yu Wenhan hadn't personally agreed, how could he have allowed his son Tuoba to do such a stupid thing? The empire is not his own family!

"Your Majesty, the two shells in the back are not controlled by anyone. They will follow the trajectory of the first shell and end up hitting the same place. Shang Yi explained calmly.

"In that case, why don't you just add a few more shells? Isn't that more certain?" Yu Wenhan didn't ask about the technical aspects of the Japanese cannon before, but he came to the scene in person because of the great stakes today.

Shang Yi said: "Because after firing three shells, this sun-shooting cannon is almost scrapped, and there is no way to fire more shells." ”

"I see. Yu Wenhan nodded.

As the aura gathered again, Shang Yi issued another order: "Open the cannon!"

......

Let's say that after the first cannon was discharged, it flew over the top of Longqian Pass, and the huge sonic boom that pierced the air caused a big disaster to the soldiers and civilians in the pass!

The porcelain in almost all homes burst instantly, and even several old brick houses collapsed.

Their ears could not hear a single small sound for three days, and they were permanently damaged.

For a long time after that, the people who came out of Longqian were famous in the empire for their use of wooden dishes and the habit of speaking in a loud voice.

This matter is completely because things were so rushed that no one thought of these details that needed attention. In fact, even if I thought about it, I am afraid that I would not have time to do it at all.

In addition to the deafening sonic boom along the way, the shells themselves shone violently.

In fact, the shell itself was flying entirely by inertia. The roar and light were not produced by any powerful formation or mechanism.

The roar is actually a continuous popping sound made by a cannonball that exceeds the speed of sound and constantly breaks through the sound barrier. The speed was so fast that the sounds were so connected that it sounded like a non-stop roar.

The luminescence is the shell of the shell, and the high-temperature heat energy generated by friction with the air makes the air close to the shell shine dazzlingly!

Such an eye-catching cannonball immediately attracted the attention of the border army of the Dark Alliance.

They sent out scouts, but they couldn't catch up at all, and could only watch as the cannonballs shot into the depths of the Dark Alliance!

Of course, they still sent an alarm to the rear through various means, such as the divine sense contact of high-level magicians.

They clearly realized that this terrifying and strange thing must be headed for the Alliance's Heaven Stealing Demon Array!

As for whether the rear has time to defend and whether it can be defended, at this time, we can only pray for the blessing of the Dark Lord.

But a moment later, another cannonball flew by with the same roar and glow!

This time, the defenders of the Dark Alliance were no longer stupidly flying in pursuit, they sounded the urgent alarm again, and waited apprehensively.

Sure enough, after a while, there was another one!

"How many are there?"

After waiting for a long time, they finally understood that there were three such things in total, shooting into the Dark Alliance's body along the same trajectory.
