Although bamboo is light and easy to process, its strength and high-temperature resistance are not enough to support the long-term, high-intensity operation of the steam engine.

Under the action of high-pressure steam, bamboo can easily deform or even break.

That’s why steam engines explode.”

He paused and continued, “Secondly, regarding the sealing problem, there is no suitable sealing material, such as rubber.

Steam engines are prone to air leakage during operation.

This would not only affect the efficiency of the steam engine, but could even cause the machine to malfunction.”

Li Shimin and others nodded frequently after listening.

They had noticed these problems before, but had never found a suitable solution.

Now after hearing what Li Haoze said, I suddenly felt enlightened.

"So, Xiaolangjun, how do you think we should improve this?"

Li Lizhi rubbed the "little princess's" hands and asked humbly.

Li Haoze thought for a moment and replied, "To solve the material problem, our first choice should be steel, especially those key parts that need to withstand high pressure and high temperature."

"Alternatively, we could try using tempered steel as a transition material, replacing areas prone to deformation with harder and more durable specialty steels."

"As for the sealing problem," he continued, "at present, it seems that the only solution is rubber."

"Rubber?" Li Shimin was no stranger to refined steel, even though it was precious and rare.

But for him, the emperor of the Tang Dynasty, it was not difficult to obtain it.

However, this was the first time he heard the word "rubber", which made him feel a little confused.

"Yes, my Lord, it is rubber.

This is a material with excellent elasticity and sealing properties, which is the key to solving the steam engine leakage problem."

Li Shimin frowned when he heard the little divine beast address him, but he still asked humbly.

"But I've never heard of this rubber. Where does it come from?"

Li Haoze smiled slightly, "Old Emperor, you don't know this!

This rubber is actually formed by the solidification of the sap of a tree.

This tree is called the rubber tree, and it grows in the far south of the South China Sea and east of the East China Sea."
