According to the method of Gao Fujijiao, Li Fayuan commanded people to carry out the initial processing of rubber and make it into a semi-finished product, and then go back to vulcanization and stamping mold to make finished rubber. In addition, the work of transplanting rubber did not stop, although he explained how to transplant it, but Li Fayuan still consulted the patriarch seriously.

In order to ensure the success of the rubber transplantation, Li Fayuan, under the advice of the patriarch, only dug the size of the bowl, and then selected the towering trees with good growth and cut dozens of bundles of branches.

After another three months, the three great ships were filled with rubber and rubber trees, as well as water and food for the voyage.

Li Fayuan found the patriarch and said: "Patriarch, there have been many disturbances for several months, and now that our goods are ready, we are ready to return, and we sincerely invite you to visit Datang, I don't know if you are willing." ”

Over the past few months, Li Fayuan helped the patriarch exterminate all the nearby tribes that threatened them, and taught them to make clothes from tree bark, and gave him a lot of cloth and porcelain brought with the ship, so that the tribesmen forgot Li Fayuan's original barbarism and were full of gratitude.

Now the tribesmen are more than ten times as many as before, and the increase in population has brought about the great development and prosperity of the tribe.

"My respected general, thank you and your soldiers for your generous gifts to my tribe, so that our tribe has better conditions to survive, and I express my deep gratitude to you on behalf of the more than 5,000 people of the tribe." The patriarch gave a salute.

"You don't have to be polite, without your help, we can't find rubber on this trip, and you help us boil rubber, as far as I said, if you intend to use rubber to trade with me Datang, your tribe will get endless treasures, and you will also build your own country at that time."

"My dear general, what you said is very true, but now many people in the tribe are still unstable, I need to stay to stabilize the tribe, and besides, I can't reach the Tang Dynasty thousands of miles away at my age, wait for the next time you come, when the time comes, I will select the young people in the clan and then sail with you, is it okay?"

"Okay, do you need me to deter the ambitious guys in the clan before I leave?" Li Fayuan asked, his so-called deterrence was killing, and the patriarch naturally understood what he meant.

The patriarch shook his head and said: "Now they are all the labor of the tribe, and the tribe cannot survive without being young and strong, and when they find that they are independent and do not live well or cannot survive in the tribe, they will stabilize, which is the blessing of the tribe, thank you for your kindness." ”

Li Fayuan was also polite, because to be honest, these people had helped him a lot, and now he let himself do it to the defenseless them, Li Fayuan couldn't bear it, and when he saw what the patriarch said, he nodded with a smile.

The patriarch asked, "General, is the Tang Dynasty you said really so rich?" Is it true that the population is more than 50 million? ”

"Of course it's true, we mainly farm, and we have a vast land, so we can feed such a large population, now it is estimated that it is more than sixty million, and there are countless big cities, of course, if you hunt and cultivate according to the method I taught you, the food will be greatly abundant, and the population will naturally increase steadily."

"Thank you, general, thank you for bringing us the gospel."

What is this, we are here to plunder, and they are still grateful to themselves, and fortunately, Li Fayuan is thick enough and black enough, otherwise he really can't afford to be thanked by others.

The patriarch took out a bag from his arms, handed Li Fayuan a bag of animal skins and said: "This is the seed that our clan has exchanged for their lives over the years, in order to express our gratitude, the elders of the clan have unanimously discussed with me as a thank you gift, and please don't refuse." ”

Although I don't know what these seeds are and whether they can be planted in Datang, Li Fayuan still took them with both hands and expressed his highest gratitude, seeds, which Datang dreamed of.

More than a month has passed, and all the work is well prepared. On this day, the wind and the sun were beautiful, and on the wharf built in the harbor, Li Fayuan and others waved goodbye to the old patriarch and others.

"May the god of the sea bless you, my beloved general, bless you with a smooth arrival in the heavenly Tang Dynasty, and at the same time, please wait for me to express my supreme respect to His Majesty the Emperor of the Celestial Empire."

"Thank you, Patriarch, I look forward to the next time you can arrive in Datang with me."

"This will be my biggest wish for the rest of my life."

"It's getting late, goodbye, and I hope you and your people get through as well as possible."

"Thank you!"

Li Fayuan ordered all to board the ship, as the sails were raised, the three large ships that had been repaired slowly sailed out of the port, Li Fayuan looked at the port town built by himself on the shore, and was full of emotion in his heart, and silently blessed them in his heart.

On the ship, whether sailors, soldiers, or gentlemen and students, all waved excitedly and said goodbye to the people on the shore, they did not expect the trip to be so smooth, although they also experienced a hurricane on the sea when they came, but the purpose of the trip was achieved, and a fine nautical chart was also drawn, which was the greatest wealth, laying the foundation for the future Tang Dynasty to conquer this rich land.

Now that the task has been completed, and new friends have been made thousands of miles away, and now they have finally embarked on the journey back to Datang, everyone can't hide the excitement in their hearts, so they all wave their hands hard.

When the big ship sailed out of the harbor and disappeared into the horizon, the old patriarch on the shore dispersed with his people.

A sturdy young man was still longing: "Patriarch, do you say that the country that General Li said is so strong really exists?" ”

"It should exist, the outside world is very big, we are just a corner here, and another one, it can be seen from the weapons in the hands of the samurai who came with General Li, their weapons are made of fine iron, and what is even more frightening is their kind of weapons that can thunder, because of military discipline, we can't see it, it's a pity."

"General Li said that they have a academy called Qingbei Academy in Datang, which is the holy place for Datang to do learning, and the weapon that sends out the thunder is the result of the academy, I really hope that one day I can visit Datang and bring back advanced weapons to protect our people from infringement."

"Nick work hard, you're still young, you'll have a chance."

"I really yearn for that god-like kingdom, listening to what those soldiers said is so good, I can't sleep for days and think about it repeatedly."

"Heru, dispel your thoughts, your mother is now frail and sick, and she can't do without your care, you should find a suitable tribal woman to marry as soon as possible, and leave offspring."

Hearing the patriarch say this, Herumaihuang's face was rarely flushed, which provoked a burst of ridicule from children of the same age.

Although Li Fayuan and the others are gone, they have taught them the methods of clearing the wasteland and farming, which still need to be explored by them. More than 5,000 mouths still need to be fed, fortunately Li Fayuan also gave them a lot of iron tools, and promised that if they can find iron ore next time, they can consider teaching them a simple method of iron smelting, so that they can directly step from the semi-stone age into the iron age, which is what the old patriarch cares about the most.
