When Sima Hui was in the Shangyong area, Zhuge Guo was in the Longxi area, the east and west defense lines were quite long, and it was very difficult to defend, and it was not ruled out that Cao Cao's dead army would bypass Shangyong and Longxi, and they might enter Hanzhong from the Western Regions.

This time, the three of us led the troops to leave Jingzhou, first to Shangyong, Sima Hui was in Shangyong is arranging the formation, he was overjoyed when he knew that I was coming.

The news of the sentinel detective said that the Wei army had recently made a big move, and the fine work in Cao Ying's work also flew pigeons to pass on the book, which said: Recently, Cao Cao rebuilt the army of the dead, and dug up most of the dead people and corpses in the northern region, which were as many as one million, gathered in one place, and looked black and oppressive.

Above the base of the Legion of the Dead, black crows flew all day long.

Sima Hui has written this information and sent it to Hanzhong, Zhuge Liang has learned the news, he has transported the first batch of grain and grass to Shangyong, the second batch of grain and grass is about to be sent, the destination is Longxi, although the wheat in Longxi this year is very good, but it is not yet the harvest season, Zhuge Liang is worried that the northern front is about to face a time-consuming war, the grain and grass are not enough, I am afraid that the defense will easily collapse.

Zhuge Liang wrote that he would soon lead a large army north to fight against Cao Cao.

Zhuge Guo heard that she came back from Nanzhong and came to Shangyong, and she came from Longxi to show me her ability to deploy troops.

Zhao Yun, Ma Chao, Xiahoudun and Zhang Liao respectively led the army to the north, and when discussing with Sima Hui about the fight against Cao's army, Zhao Yun said: When I was in Nanzhong, I led the army to pursue the Mengqi people, and I might as well kill into the fog, and a few people suddenly appeared in the fog, luring our army to chase and kill to the depths of the jungle, and fell into the trick of the gorgon, and was plundered into the cave.

Zhao Yun paused, his face was ashamed, the eldest husband was captured by a demon girl, it is indeed a little difficult to say, but he continued: Although he was captured by the demon girl, he did not eat half of her rice, and relied on the chocolate given by Xia Gongzi to support his physical strength, and dared to ask Xia Gongzi, what is this food similar to Chinese medicine pills, it can resist hunger, this kind of food, easy to carry, if it can be carried by our sergeants, it is very convenient, and it can greatly increase the combat effectiveness of our army.

Ma Chao has also eaten my chocolate, not only Ma Chao and Zhao Yun, but several people here have eaten it, and they all said: Yes, Xia Gongzi, what is this thing, why not use it as military food.

I stood up and said to everyone: this is chocolate, a high-energy, high-calorie sweet, in Western countries, this food is often used as a kind of hunger food, easy to carry, when hungry to eat a piece can support the human body for a long time.

Although Sima Hui is a Taoist figure, it is the first time he has heard of chocolate, and he said: Where does this kind of thing grow?

I said: things are good things, the main raw material of chocolate is cocoa beans, and you can make chocolate by grinding cocoa beans into powder, but this kind of thing grows in Africa and South America, far away from us, and to Central and South America, you need to build large ships, cross the ocean, reach South Africa, and transport cocoa beans, coffee beans and other things from there.

Sima Hui asked me: How far is it to South America?

I took out the map of the world and spread it on the table, pointed to South America, and pointed to Asia where we are now, and said: Look, from here to here, let's not talk about land alone, let's talk about the ocean, to cross the Pacific Ocean, if you go from the west, you can go a little less ocean, but the land is not necessarily less dangerous than the ocean, and the transportation of cocoa butter, the ship is relatively less laborious, if it is pulled by a horse-drawn carriage, it may be more troublesome, although the Silk Road is a key road to the West, but I think, It is more feasible to go to the Americas by steamer, and the distance is tens of thousands of kilometers.

Sima Hui was taken aback, he knew astronomy and geography well, looked at the map, shook his head again and again, he said: This is simply the other side of the world, to go to the other side of the world to find food, this is ......

At this time, Zhuge Guo, who had not spoken, spoke: I see that the speed of the boat on the water is much faster than that of a person.

Zhuge Guo is only fifteen or sixteen years old, and he is so confident about this matter, I turned around and said: Do you think you are Columbus?

Zhuge Guo didn't understand what I meant: Columbus? What Columbus?

I explained: At that time, Columbus drove a ship from here to here, and discovered the New World, and there was also a person named Zheng He in my country, who was the famous Zheng He who went to the Western Ocean.

Zhuge Guo stood next to me and immediately said: We can also go to the West!

If I say that if I sail a ship, it is not realistic to transport cocoa beans to the Americas according to our current navigation technology, and it is estimated that the journey will take a year.

Zhuge Guo pouted and said: Exaggerated.

I looked at the map, just talking about South America, ignoring Africa, it's closer to Africa, cocoa beans generally grow near the equator.

I pointed to Africa on the map and said: go here, cocoa beans grow here, we go through the Indian Ocean, try to avoid taking the land route, there are many countries here, there is nothing to rob before we go to Africa, cross the Indian Ocean, even if there are pirates on the ocean, but we send warships to protect the transport ships, there should be no problem.

Zhuge Guo took my arm and said, "I said that you must have a way."

However, to go to Africa, it will take half a year to go back and forth, to say the least, and there are no ships that can sail far away.

Sima Hui said: At present, if you want to build a ship, you can only hand it over to Sun Wu, who is tied to Jiangdong, and the shipbuilding technology is relatively advanced.

I said, "What Mr. said is very true, I know a little bit about shipbuilding technology, and I can help Sun Wu improve his ship technology."

When I was in school, I participated in many activities of model aircraft in junior high school, and in the high school of Thirty Mile Town, I made some aircraft carriers with my own hands, which are similar, although the technology of the Three Kingdoms is backward, and many auxiliary technologies are not in place, which will definitely lead to the technology I provide cannot be realized, but I will apply some of the knowledge I have learned to the ship, and it will definitely be able to sail away.

I said that it could be done, that I could help build ships for the voyage, and everyone was very happy, but now we could not wait for a year later, and I said to everyone: military rations can be relied on more than chocolate, and there are many things that can be used as military rations for marching and fighting.

For example, canned beef, and beef jerky, especially beef jerky, don't require any advanced technology.

Later, I personally guided and built many houses for drying beef jerky, which is not to be mentioned later.

Everyone was discussing the matter of military rations, and someone came to report that there was a situation on the Longxi front, and asked Zhuge Guo to return quickly.

Longxi can't be lost, Longxi has planted a large area of wheat this year, and these wheat may be the war preparation food of the Shu army in the coming year, so Zhuge Guo got up immediately, I said wait.
