In the sinkhole, the yin wind whistled and whistled away.

When blowing through Su Tianju, the fragrant wood spirit grass planted on the side of the tower swayed for a while, turning up emerald green waves. The spirit deer raised in the middle of Sutian raised their heads in the sound of the wind and waves, and among the green leaves flying with the wind, their eyes moved with the yin wind in the air.

In that tower, the ghost mother's rare eyebrows danced, looking at the Nine Heavens Mirror, and the eyes that were as black as paint were full of excitement and excitement.

This ancient god technology product that was used to deal with the Demon God Sky Cavalry back then, she hadn't seen it for a long, long time. At this moment, seeing that Lai Yueqi and Ying Ying had studied the books of the ancient gods, it took more than a year to make the Nine Mirrors, which were exactly the same as the Nine Mirrors used by the ancient gods, and the ghost mother seemed to have seen an old friend who had not seen her for a long time, and her heart was irrepressible.

Before Emperor Xudu came to power, a cruel and tragic war between gods and demons broke out in the underworld, and many ancient god technologies were lost. The ancient gods, who were victorious and survived, soon split into two factions in the human world, the evil gods and the good gods, and launched a great war to destroy and protect the souls of people.

Many of the ancient gods who were proficient in kitsch and obscene techniques died in the great war on earth, and the few remaining ancient god technologies were lost a lot. Since then, the civilization that the ancient gods once created was as bright as the stars, and it has also dimmed. After the Emperor Xudu came to power, he wantonly destroyed the traces and writings left by the ancient gods, and called it conquest, but in fact, he was afraid that the ancient gods were once like a dazzling sun, and the radiant skills and magic skills would fall into the hands of his enemies.

Emperor Xudu had no choice but to cut his love and destroy most of them. As for those that cannot be destroyed, they are all collected and hidden.

Since then, most of the ancient god technology has died out in the Netherworld, including the ancient books that record the technology and magic of the demon gods who have been working against the ancient gods for hundreds of years, and many of them have been burned by the Emperor Xudu.

After that, because of the prophecy, the Emperor Xudu did not dare to let the souls of knowledgeable people stay in the underworld for too long. Therefore, the technology of the underworld has not progressed, and all technology has stagnated. The self-contained underworld is obviously ahead of the world's thousands of years of science and technology, but it has been completely surpassed by the world for thousands of years.

Such days continued until Xiao Shizhu came from the human world to the underworld.

This human soul who has not studied in college and does not have many diplomas, knows more than too many cultured and pretentious ghosts that technology determines whether a ghost country is strong or not. And advanced technology is also the source of the progress of the ghost country.

In the tower of Sutianju.

Xiao Shizhu looked at his wife's happy appearance and smiled indifferently. He turned his eyes to look at the Nine Heavens Mirror in front of him. After looking at it carefully, he also recognized that among the eight trapezoidal crystal mirrors, the small red dots that appeared were forming a large mandarin duck array, moving slowly on the crystal mirror.

It is in line with the current situation of the air forces of the Nine Shadows Kingdom that are busy patrolling in the air around Yuque City at this moment.

"It's like a radar on earth. Xiao Shizhu thought silently, turned his eyes to Lai Yueqi and asked, "What is the principle of this Nine Heavens Mirror?"

"It uses soul energy and ghost energy perception sigils. Lai Yueqi held her already bulging belly with one hand, and raised her slender and calloused index finger with the other hand, and drew a circle on the Nine Heavens Mirror, saying: "The Nine Heavens Crystal made of Kunpeng blood, which can refract scenes thousands of miles away, is made into a mirror. Then, as long as you pinch out the technique to activate the perception talisman and inject the ghost qi into it, the location of the ghost qi in the air will appear on the mirror. ”。

"And continue to inject the caster's ghost energy, and control the Nine Heavens Mirror with his heart at will, he can be in the middle, on this piece of Kunpeng Blood Crystal, reflecting the aerial scene that the ghost who uses the Nine Heavens Mirror wants to see. Ying Ying, who took over the words, changed the ten fingers of her hands and changed her technique.

Immediately afterwards, on the round mirror in the middle of the Nine Heavens Mirror, the scene of white clouds was reflected. And on the top of the clouds, several air cavalry of the Nine Shadows Kingdom were flying in the clouds, flying in the wind.

"Well, it's really convenient. Seeing this, Xiao Shizhu nodded, and there was finally a trace of excitement in his eyes, which disappeared in a flash, but then he shouted in his heart to make people happy.

If this thing had been made earlier, maybe in the war of Weishan Castle, it would have been able to resist the enemy outside the city in time.

It's just that Xiao Shizhu also knows the truth that the world is impermanent. Therefore, the disappointment in his heart was as fleeting as the excitement in Fang Cai's eyes.

"Chen Ruo, send Mrs. Lai back to the palace. Xiao Shizhu glanced at Lai Yueqi, the bulging belly, and said slowly.

Lai Yueqi's bulging stomach was not filled with undigested supper overnight, but his Xiao Shizhu's flesh and bones. Lai Yueqi is no better than the ghost mother and Tu Yaoqing, after all, she was born as a Yanshi and drank the secret medicine of sterilization. Don't be a ghost mother who does everything possible to help her heal, and she can't be pregnant. But she will only have this flesh and blood in her life, so Xiao Shizhu still takes special care of her now.

When Chen Ruo responded and was about to escort Lai Yueqi back to the palace, Xiao Shizhu said to Lai Yueqi in a deep voice with a little displeasure: "You don't care about the affairs of the ordnance supervisor for now, give me an honest and peaceful baby; ”。

When Lai Yueqi heard this, not only did she not get angry, but after smiling faintly, she said goodbye to the ghost mother and walked away slowly with Chenruo.

"National teacher, I have to trouble you in this matter, give the moon girl more a safe baby. Before Lai Yueqi left, the ghost mother said to Yingying.

"No. Yingying didn't shirk it, and immediately responded.

At the same time, Su Tianju and the Ordnance Supervisor are ready to cooperate and start mass production of the Nine Mirrors. Do you calculate, how many craftsmen and dark coins will be needed?" Getting back to business, Xiao Shizhu asked this, and walked straight to the chair on the side and sat down, but his gaze was still on the Nine Heavens Mirror.

If it can be equipped to all parts of the Nine Shadows Country, as well as every fleet of sailors, with the Xiancha Flying Thunder Vehicle of the Nine Shadows Country, and the well-trained Air Cavalry Flying Army, the Nine Shadows Kingdom will no longer be afraid of the Emperor Xudu's Firmament Army, and the sudden air attack launched by the Emperor Xudu.

No, it should no longer be afraid of any of the ghost country's air forces and air raids.

Thinking of this, Xiao Shizhu, who was also rarely excited and excited, trembled suddenly with the index finger and middle finger of his right hand.

"With our current land and the number of fleets, if we need to equip it, it will cost at least 70,000 (700 million) taels of underworld silver, and it can't be the underworld banknotes printed in the world, but the real gold and silver refined from the underworld silver mines. After a quick calculation in her heart, Ying Ying estimated that she gave Xiao Shizhu a number.

This is the financial revenue of the Nine Shadows Kingdom for more than two years; at this time, the border is still under construction, and the foreign war is still continuing, and it seems that it is only more than two years of financial revenue, which is also a large amount.

No matter how rich the Nine Shadows Country is, if you have to take out so much money at once, it will also make the treasury empty.

"Okay, I'll approve the money when I go back. Xiao Shizhu didn't think about it for too long, so he gritted his teeth and responded.

Practical science and technology is the highland, practical science and technology is the future, and practical investment in science and technology is a long-term return and the foundation of hegemony. It can also make the ghost soldiers of the Nine Shadows Kingdom invincible on the battlefield, and Xiao Shizhu knows these truths.

He would rather eat less good food, use less good utensils, wear fewer gorgeous clothes, and save money to invest in various technologies.

"Pass my orders. Then he turned his head to Qing Lan, who was close to him, and said categorically: "From today onwards, I will explain my dietary expenses under the dietary monitoring system, and I will not eat meat during the New Year's holidays." Three meals a day of gruel and pickles, and a boiled egg for breakfast. All the money that has been saved is deposited in the treasury. In addition, the renovation and maintenance of the palaces and pavilions inside and outside the palace, as well as the purchase of utensils in the palace at the beginning of the new year, were immediately canceled, and the old objects were used. Tell Tianguan Lu Wu to return the money to the treasury immediately and hand it over to the money cabinet ghosts who take care of the treasury, so that they can immediately enter the treasury in case of emergency. ”......

In Dongyizhou, a hundred miles east of Weishan City, in the air, the few immortal chariots of the Nine Shadows Kingdom, escorted by countless flying thunder vehicles and air cavalry, flew away in the wind and headed west.

The wings that grew horizontally on his back folded Yu Rong stood at the head of the largest Xianchacha. The oncoming wind blew Yu Rong and couldn't help but squint his eyes.

Two days ago, he received a strict order from Yuque City, and he must rush to Weishan City on the third day to rush to the aid of Black Impermanence.

Yu Rong received the order and went on the road non-stop. In order to save time, he had his troops assembled along the way. Gather all the way along the way, and constantly assemble the air troops of the Nine Shadows Kingdom that are going to Weishan City to support along the way, one by one.

He also collected the support materials for Weishan City from all over the way along the way, so that the supplies and ghost soldiers did not have to assemble in front of him first, but saved time.

By the time he was about to arrive at Weishan City, Yu Rong had already gathered more than 100,000 air cavalry and flying troops, as well as tens of thousands of flying thunder vehicles. A huge air force covered the sky and the sun, and with Yu Rong and Xiancha, they were speeding westward.

It's just that the tragic battle in Weishan City, Yu Rong has also heard about it a little, looking ahead, the white clouds are long, and the distance from Weishan City is getting closer and closer, but Yu Rong is also more and more worried.

Who knows what has become of the city now? The battle report mentions that half of the castle has been burned to blackened ruins. It is said that even the road surface melted a lot in the flames. Even if you don't see it with your own eyes, just imagine the tragic scene, Yu Rong, a veteran of the battlefield who has been rolling on the battlefield for many years, can't help but tremble slightly in the corners of his eyes.

There is one more day, and the deadline is still one day away. However, the army led by Yu Rong was no more than a hundred miles away from Weishan City.

Along the way, he kept the troops whipping up, and the furnace that generated the flight power in the flying thunder car and the Xiancha was not extinguished, just so that he could rush to Weishan City as quickly as possible.

The wind was strong, and the supple white feathers on the wings on Yu Rong's back shook with the wind. When you squint, you can't see it quickly, and it has become a pair of small eyes that have been staring straight ahead.

"General Haei, I received a message from Weishan Castle, and the battle over there has come to an end at this time. The battered Firmament Army retreated to the sea to rest. The fungus man who accompanied the army walked over, stood beside Yu Rong and spoke quickly.

"What about the casualties?" asked Yu Rong in a calm tone as much as he could, after secretly breathing a sigh of relief.

Yu Rong knew that if it weren't for the heavy casualties of the ghost soldiers in the city, Xiao Shizhu would definitely not let him arrive within three days. Yu Rong could vaguely imagine how tragic it was in Weishan City.

"It's not optimistic, because the ghost people have tunnel protection, the casualties are not serious. But the ghost soldiers stationed in it have already suffered two-thirds of the casualties. The fungus man frowned and sighed softly.

"The herald ordered the whole army to advance at full speed, and hurried to Weishan City. Yu Rong didn't sigh, didn't say much else, just ordered categorically.
