When the transmission and the internal combustion engine are combined, products that transcend the times will be born.

Although cars with only a transmitter can also be used, such cars cannot reverse, which brings great inconvenience.

It was until the advent of the later gearbox that the car became more convenient.

It was also from that time that the convenience of cars began to show itself.

Considering the technical difficulties, Liu Zheng paused and said: "Let's first develop a gearbox with a forward gear and a reverse gear. Combined with the operation of the internal combustion engine, we need a vehicle that can walk without horses."

Upon hearing such a request, the director obviously didn't believe his ears, but Stephenson, who was transferred to the engine research room, was extremely excited.

When he said that he would apply a giant steam engine to a car, no one would believe it. As a result, Long Yan directly built such a machine at that time.

And now Liu Zheng said whimsically that he would build a car that can walk without horses. He was inexplicably excited.

This is also a study that is unlikely to succeed.

But it doesn't mean that it really won't succeed.

He believed that with the current level of technology, it might not be a big problem anymore. After all, battleships and steam trains that were more difficult than this kind of thing had already been built.

The director sighed and said: "I will try it, but now there is no way to guarantee success."

Liu Zheng nodded. This kind of thing still requires a long time of research, but problems with steam engines have gradually been exposed.

Most steam engines are not convenient to carry.

Moreover, the current steam engine has reached a bottleneck in terms of power, and it is difficult to improve it.

This is controlled by the structure of the steam engine and current technical barriers.

And now Britain has used Longyan's steam engine technology to create a Dreadnought-class battleship.

A battleship of this level already poses a danger to Long Yan to a certain extent.

It was only a matter of time before steam engine technology was broken through.

Therefore, for Long Yan, the invention of the internal combustion engine became particularly important.

The successful production of the internal combustion engine means that Long Yan will be able to research such a terrifying weapon as the tank.

A super weapon that is nearly invincible on land.

The advent of tanks can directly change the current military combat pattern, unlike the advent of artillery and muskets.

Although the troops use hot weapons, more cold weapons and cavalry are already the most damaging arms on the battlefield.

But after the advent of tanks, the status of cavalry will decline infinitely. Faced with such a crushing weapon that cannot be destroyed at all.

The enemy's artillery and musketry were in vain.

Thinking of this, Liu Zheng's heart beat excitedly, but the premise of all this must be based on the success of mature and stable research on internal combustion engines.

...

At this time, America.

The party at George's house has come to an end.

Qin was so drunk that Lingding was so drunk that Earl Lane carried her to the car when she left. For such a humiliating behavior, George could only say sorry.

There was no way he could drink less to Qin. Maybe if he drank more, he could forget all the unpleasantness.

That's what he thought.

When Earl Lane left, he said to George: "I hope that after today, Qin will not want to see you when she wakes up."

George nodded and said, "May your wish come true."

Earl Lane boarded the luxurious carriage and set off to leave.
