When he woke up, technician Li Yan became a steam boiler operator in 1970.

Faced with an era when families were penniless and coal and passion were burning together, others were thinking about how to shout slogans, but Li Yan was only thinking about how to make the boiler burn more vigorously and make life with his wife and children more comfortable.

Others see him as a big, rough guy sweating profusely, but he is actually the most leisurely "invisible boss" in the maintenance depot.

Using Newtonian mechanics to heat boilers? Coal consumption dropped by 30%, a feat the experienced boiler owner called a miracle.

· Make a home heater out of scrap parts? Keep your whole family warm during the coldest days of winter.

Giving a locomotive a "physical examination"? Fault hazards are easily identified, and safety production champions are easily awarded.

The trains that crisscrossed the country formed his information network, and the diverse passengers formed his personal connections. He offered guidance to returning educated youth, provided timely assistance to struggling experts, and with a glass of wine and a few prophecies, he paved a leisurely and stable path for himself amidst the whirlwind of the times.

When the spring breeze of reform blew, everyone was surprised to find that this train driver who always smiled had already stood at the top of the wave.

This is a leisurely daily life under the roar of steam, and also a legend of an ordinary person gently embracing an era with knowledge.

My uncle is the director of the FBI!

What?

You ask who I am?

Um, my last name is Hoover.

Li Ziteng's famous sayings, everyone here...

I traveled back to the 1950s and only had a 1-cubic-meter storage ring.

What should I do?

When I was worried, something even more terrible happened.

Both my parents were killed in front of me, and there was a 4-year-old sister in my arms.

Is this a king bomb?

Li Qiwei transmigrated as a rich young master of the Qing Dynasty who studied in Cambridge, England.

At this time, it was 1900, and science was flourishing.

In particular, physics is about to open up the world.

In the same year, Planck will put forward the concept of "quantum" and open up quantum mechanics.

Five years later, Einstein will publish the theory of relativity that shocked the world.

Later, Bohr, Schrödinger, Heisenberg, De Broglie and others were born.

These great names represent the highest peak of human wisdom, shining like stars.

Li Qiwei, who was a doctor of physics in his previous life, is excited at this moment.

He has no intention of participating in the change of world order, nor does he care about the ups and downs of countries.

He just wants to become the god of physics and guide the stars of physics.

Finally, he wants to make Huaxia Science stand at the top of the world.

In 1890, the sun was high over Surabaya on Java Island. Liu Yiming, who traveled from the modern times, had just woken up in Surabaya. Before he could figure out his situation, he was told that the natives were about to start a riot... The first three volumes: Deter the natives - Fight for Surabaya - Unify Java. The war was mainly carried out through the asymmetric development of industry, agriculture and military equipment. The first hundred chapters had a slower pace, with more battles and military descriptions, and less in the latter part. Fighting the Dutch was like a novice village, and you could beat them by upgrading and equipping them randomly.

Facing the imminent fall of his homeland, he joins forces with legendary figures like Scharnhorst, Gneisenau, and Clausewitz, striving to change Prussia’s doomed fate.

This is a sweeping epic of war — a vivid portrait of iron-willed soldiers fighting fiercely for their nation’s survival.

While European merchant ships were still searching for new trade routes across the world's oceans in the 17th century, in the distant region of Australia, the sound of roaring industrial machines could be heard.

Truckloads of coal are being shipped to factories, and countless industrial products are flowing to overseas markets.

When we come to trade with you with our goods, please do not let the cloth drop from our hands and hold the muskets behind our backs.

When the line infantry marched toward the earth in neat steps, when the cold cannons fired scorching shells.

Jiang Zirui stood at the harbor, watching the ironclad ships and merchant ships raise their red dragon flags, and pointed his finger into the distance.

"Let's go! Free trade!"
