Military industry genius Yang Wei returned to the eve of the counterattack against Vietnam because of an accident and took the initiative to enter the Firearms Research Institute. Starting from solving the defects of the "notorious" firearms, the sniper rifles, 81 bars, and grenades were born one by one, with their performance far exceeding that of the time.

Tanks, armored vehicles, etc., the synthetic battalion appeared in the PLA queue decades ahead of schedule...

Starting from canard fighter jets, then to stealth canards, and finally to canards...

"I traveled back to Hong Kong in the 1970s and only wanted to make money. Why are you forcing me?" Zhang Jun was very distressed. The fans of this generation were not good and always threatened him.

Movie fan: If you don’t make movies, I won’t buy your Subor game console!

Fan: Jun Ge, if you don’t release an album, I won’t buy your Walkman!

Comic fans: Please publish comics soon, or I won’t buy your Apple computer!

Novel fan: If you stop updating again, I will never buy your newspaper again!

…

Damn, this is simply too much!

Zhang Jun was furious, but to make money, he had to toil away on side projects like making movies and releasing albums. Unexpectedly, he became a world-class superstar... replacing Michael Jackson, Leonardo DiCaprio, James Cameron, Spielberg...

Travel through the world of The Return of the Condor Heroes and become the protagonist Yang Guo.

Thinking of the upcoming scene of the late Southern Song Dynasty, with its stormy and chaotic times, Yang Guo was paralyzed!

No, as a modern office worker, why did you ask me to travel through time? My fried chicken, my French fries, my happy water, all gone.

Fortunately, at the critical moment, the Fishing of the Heavens system was activated.

[Congratulations to the host, you obtained the Nine Yang Magical Art by fishing]

[Congratulations to the host, you got the Dugu Nine Swords by fishing]

[Congratulations to the host, you gained one year of training experience by fishing]

From then on, Yang Guo's strength increased rapidly. He had all the skills and internal strength, soldiers, money and food, and steam and technology all exploded.

What? Decades later, the Mongolian army marched south to capture Xiangyang City, leading to Guo Jing and his wife dying for their country?

Sorry, I can’t wait that long. My subordinates are already impatient to put the imperial robe on me!

A different late Han Dynasty, a different struggle for hegemony.

The rising Xu Shu, the surviving Pang Tong, and the reused Zhao Yun,

The still-living Guo Fengxiao and the unrivaled commander Zhou Gongjin. Everything unfolds in the Three Kingdoms era, during the Qin Restoration. Qin possesses elite warriors, who can challenge them?

Yue Zhenshan traveled through the Republic of China and found that this world had Qigong cultivation, poisonous Gu corpse refining, alchemical magic, and strange scholars who talked about mysterious science. He started with a blacksmith shop and suppressed the world with iron and blood...

Reborn in 1977 as an educated youth sent to work in the suburbs of Beijing, Wang Haoran needs to reverse more than just his personal destiny! Family, country, and world affairs, the country and the society are all under my control!

This book tells the story of a time traveler who becomes a national treasure-level scientist by relying on his scientific research ability. When he came, the country was poor and backward. 20 years later, a prosperous and civilized country has risen!

In his previous life, Du Yun worked himself to death in order to make money and improve his family's already poor life.

Unexpectedly, he did not report to the underworld as folk legends said, but was directly reincarnated into the royal family of Dongxing Kingdom and became the ninth prince.

Because he has never drunk Meng Po soup, he has memories of his past life.

Feeling tired from the previous life and having a noble status in this life, he just wants to give up and live the leisurely life he wants.

Unfortunately, things don't always go as planned. Even if he doesn't fight or compete, malice will come to him automatically.

Fortunately, he has a mysterious seed in his body that can assist in cultivation and enhance his understanding, and even sense the malice of others, so he can avoid danger and seek good fortune, as well as some other abilities that allow him to grow safely under various calculations.

Therefore, while enriching himself, he hid himself and acted like an unlearned person, so that those with malicious intentions would turn their attention to other outstanding princes.

With fewer and fewer calculations, the unappreciated Du Yun can finally grow up in peace and live a carefree life.

However, he also knew that this was only temporary. When the battle for the throne began, even if he had no interest in that position, he would be forced to get involved.

Therefore, while growing up, he is also secretly developing his power to facilitate his future carefree life.

In this way, even if you have to fight in the future, you will have a certain foundation and will not be helpless.

As for the final effect, we can only wait and see future developments.

"Yan Sihan~ Hug~" She moved closer and hugged the man's waist.

The man suppressed his voice: "Jiaojiao, you have no chance anymore."

[Sweet and scheming little queen x extremely indulgent Regent King]

Entering the world of the Red Mansion, he is a prince unrecognized by his father.

On the day he first meets his father, he asks, "Your Majesty, do you remember Jiang Xuelian by Xuanwu Lake that year?" Father, you are unwilling to acknowledge me as your prince, but I insist you do.

Father, you are unwilling to pass the throne to me, but I insist you do.

I love the golden hairpin, but I love the land even more.

"A complete set of design drawings for the F-4 Phantom II fighter, Sidewinder missiles..."
