Li Qieyou didn't expect that rubber grass also existed on the Bank of Swan Lake, the nest of sand thieves.

In fact, he doesn't know rubber grass. After all, not many people have seen this kind of thing in future generations. Even the name of rubber grass is occasionally seen by Li Qieyou when surfing the Internet.

It was not until that day that he collected wild grapes and took them back to the sand bandit camp to make wine that he noticed his clothes and rubbed some milky white colloidal substances.

He tried to wipe it with his hand, but found that the colloidal material had solidified.

This elastic solid made Li forget his worries and immediately flashed a lightning bolt - natural rubber!

Of course, natural rubber will not appear inexplicably in the sand theft camp.

The only possibility is that when he went out to collect wild grapes by the lake, his clothes rubbed the glue liquid from rubber grass, and then he left this small piece of natural rubber after solidification.

With this in mind, Li Qieyou immediately rushed out of the sand thief camp and ran to the area where he had collected wild grapes.

After a careful search, Li Qieyou finally found a plant that looked like a dandelion. One of the stems and veins had been broken, and there were also milky elastic colloids on it.

Li forgot to worry and was overjoyed. After determining the shape of rubber grass, he searched around and found a lot of rubber grass.

This unexpected joy immediately made Li forget his worries and gave birth to the hope of escape.

He has been caught by sand thieves for a whole year. His wife in Chang'an should have given birth to his child. The idea of going home is stimulating him at any time, almost driving him crazy.

Taking the opportunity of making wine for the sand thieves, Li forget worry secretly collected a lot of saltpeter, sulfur and charcoal and made some explosives.

He even thought about threatening the sand thief leader with these explosives in exchange for his chance to escape.

Only when he calmed down did he reluctantly give up the idea of dying.

In any case, as long as he is alive, there is hope of going home.

The accidental discovery of rubber grass made Li forget worry immediately think of the same vehicle he and Su Changqing had figured out to cross the desert for the army, that is, sand boat.

When Su Changqing visited North America, he once saw someone playing this novel thing called sand boat in the desert.

In short, a sand boat is like a sailboat traveling in the desert.

The structure is also very simple. The lower part is a wooden board with four rubber wheels, and the upper part is equipped with a sail supported by a movable mast.

Driving a sand boat is like driving a sailboat. The wind drives the sand boat to move quickly in the desert. Driven by the wind, the sand boat can even run nearly 80 kilometers per hour in the desert.

Li forgot to worry and finally did not choose the sand boat as a tool for the army to cross the desert, just because there was no rubber tire, so he had to give up.

Now that he has found rubber grass in the sand stealing camp, it means that he can collect natural rubber to make tires, and then use sand boats to escape from the sand stealing camp.

As long as we grasp the opportunity and drive at a speed of 80 kilometers per hour, those sand thieves will be tired to death, and it is impossible to catch up with him.

After all, the fastest speed of a camel running is only about 40 kilometers, and it doesn't last long. As long as the sand boat has the wind and goes with the wind, it can escape quickly.

Today, there are only two problems to be solved.

One is how to collect rubber to make tires. The other is that he can't manipulate sails and needs to explore slowly.

But these two problems are not difficult.

First of all, he doesn't need the pneumatic professional tires of later generations. He just needs to make four elastic solid tires.

Although untreated natural rubber is not resistant to aging, this has no impact on Li forget worry. He made tires just to escape and did not need long-term use.

The way he can think of is to make several tire molds, and then collect the rubber liquid of rubber grass every day and inject it into the mold to let it naturally solidify into natural rubber.

When the rubber liquid fills the mold, the round natural rubber tire is obtained.

Although the strength and durability of the tires made in this way must be very low, Li forgets to worry about so much.

As for learning to sail, he also came up with a way.

Swan Lake covers a very wide area, and there are a large number of fish resources in the lake.

But these sand thieves are lazy people, otherwise they won't make a living by looting, so they won't do fishing.

So Li forgets worry and asks Du Qing to plead with the leader of the sand thieves. He is willing to go down to the lake to fish for the sand thieves to improve their food.

Sand thieves will not refuse such a thing.

Anyway, the Swan Lake is surrounded by the vast desert. I don't worry that Li forgets to worry and will sail away.

The sand thief leader happily agreed to Li forgetful's request and asked the craftsmen captured by them in the camp to build a small boat for Li forgetful's requirements.

Unlike the traditional rowing boat in the Tang Dynasty, Li QIAOYOU asked craftsmen to install a sail on the boat for him.

His purpose is very simple, that is to take the opportunity of helping sand steal fishing to practice how to manipulate sails.

Li Qieyou had never been in contact with sails. At the beginning of his practice, the sailboat was not obedient at all and kept spinning in the water. Instead, the sand thieves looked at it as a joke, pointed at it and made fun of it.

Ignoring the ridicule of sand thieves, he repeatedly went to the lake to practice boating every day, and collected the rubber liquid of rubber grass by the lake and injected it into the tire mold.

After practicing for nearly half a year, Li forget worry's ability to manipulate the sail has become perfect, and the four rubber tires have been made, and the conditions for escape are finally ripe.

He originally wanted to take Du Qing's father and daughter to escape, but Du Qing shook his head and refused when he learned of his escape plan.

"My Lord, if you take the slave and my father, you will have two more burdens, and you may not be able to escape from the sand thieves. The slave is willing to stay and cover for my Lord, and wait here for my Lord to lead a large army to save the slave."

Li forgets to worry that Du Qing's words are not wrong. If the sand boat carries three people, the speed will be much slower, and he has to prepare three people's food and water, which is heavier.

Du Qing's father still lacks legs. It's really inconvenient if he wants to run for his life with him.

Li Qieyou, who was not hypocritical, immediately assured Du Qing, "don't worry, Qing Niang. I, Li Qieyou, swear to heaven that after I successfully escaped back to Datang, I will lead an army to exterminate sand thieves and rescue Qing Niang immediately! If I break this oath, heaven will strike and thunder, and I will not die!"

Du Qing quickly bowed down: "the Lord is serious, and the slave naturally believes in the Lord."

Therefore, Li forgot to worry and finally chose to escape alone.

But neither he nor Du Qing could have expected that Li forgetful worry had successfully escaped from the sand bandit camp. In less than ten days, the old rogue Cheng Yaojin led the iron cavalry of the Tang Dynasty, such as a divine army, to destroy the sand bandit and save Du Qing's father and daughter.

In other words, if Li forgets worry and continues to stay in the sand theft camp, he has been saved and can return to Chang'an to see his wife and children

But fortune made people, but Li forgot to worry. He didn't expect to go out of the wolf's mouth and into the tiger's den because he had run for dozens of days earlie
