The research and development of guns and cannons, of course, will not release any rumors, and Qian Heng also knows that this kind of thermal weapon should not have appeared so early in this world.

But in the face of the strength of the Jin people, Qian Heng couldn't think of anything else that could win quickly, once Bianliang City was threatened by the Jin soldiers, if he let himself completely ignore it, let the Jin soldiers and horses step on the Central Plains. Qian Heng himself couldn't get over this hurdle from his heart.

Therefore, even if he was apprehensive, he still developed the gun, but in order to deal with the eyes and ears of the imperial court, Qian Heng also specially arranged for Yu Yunwen to study a set of weapons and ammunition specifically for the Jin people.

Naturally, it is impossible to use a gun rack, but a powerful stone thrower can be used as a projection power. As for the artillery shells, there are small gunpowder shells, and there are other special oil shells, and there are these two things, and it is not a problem to balance the gold people.

In the winter of the sixth year of Xuanhe, Deng Su and Chen Dong finally returned to Qiongzhou on a sea ship.

Deng Su and Chen Dong were full of vicissitudes on their faces, but there was irrepressible excitement on their faces, and the moment they saw the port of Qiongzhou, the tears of the two flowed down at that time.

Seeing the two of them kneeling down in front of him, Qian Heng didn't say much, and patted the two of them on the shoulders hard, but he understood very well in his heart that along the way, the two of them didn't know how many crimes they would have to suffer unimaginable to ordinary people.

Two ships, and only one was left when they returned.

Mentioning this incident, Deng Su burst into tears, "The owner, the subordinates failed to protect the brothers, a total of thirty-three brothers, and a sea ship, all of which were damaged at sea!" ”

Qian Heng nodded, and his eyes were a little red, "I can understand, Zhihong, you and Shaoyang will go to rest first, and when we recover, we will talk in detail about it later!" ”

Deng Su and Chen Dong shook their heads at the same time, "The owner, this time the subordinates have gained a lot, and if they can return to Qiongzhou, they will be home, and they have too many things to tell the owner in their hearts, and the subordinates can't wait!" ”

Qian Heng suddenly laughed, too, after all, an ocean voyage that took more than a year, if you want to talk about the harvest and experience, there will definitely be a lot. These two people were originally uninhibited, and they had seen so many new worlds, how could they endure it.

Thinking of this, Qian Heng nodded in agreement, "Even so, you have to go and freshen up first, the smell on your body is going to smoke people!" ”

Deng Su and Chen Dong glanced at each other, and then realized that the situation of the two at this time was obviously a little embarrassed.

Deng Su and Chen Dong went to freshen up and clean up, and the remaining crew members who came back also went to freshen up and rest under Qian Heng's arrangement, as for those who died on the voyage, Qian Heng specially Qin Hui to deal with this matter, and asked Qin Hui to ensure that those seafarers who suffered were rewarded generously.

In just an hour, Deng Su and Chen Dong, who had cleaned up Lisuo, came to Qian Heng's residence.

"Since you are so anxious to report the good news, then tell me what you have gained!"

Deng Su and Chen Dong glanced at each other, and Deng Su said, "Shaoyang, you say it first!" ”

Chen Dong was specifically responsible for recording sea charts, and as soon as Deng Su said this, Chen Dong took out the drawings he brought with him and put them in front of Qian Heng's table.

"Owner, this is the route recorded by the subordinates on this voyage, and a rough sketch is outlined!"

When Qian Heng's eyes fell on the drawings, his face changed slightly, and he raised his head suddenly, "You came back in a circle?" ”

Chen Dong nodded again and again, with irrepressible excitement in his expression, "Owner, in the past, in the books, I always paid attention to what kind of heaven and place are round, but when I came back this time, my subordinates suddenly found that this place is also round!" ”

Qian Heng's expression changed, "Shaoyang, it's good that you understand this matter in your hearts, but don't say it, at least don't say it for the time being, and only after we have a detailed map survey and confirmation can we reveal the news!" ”

Chen Dong nodded, and he also understood what Qian Heng was worried about.

On the drawing, starting from the coast of the Great Song Dynasty, it sailed all the way east, along the west coast of the Pacific Ocean to the north, through the Aleutian Islands, and then along the west coast of the American continent, that is, the east coast of the Pacific Ocean, until it sailed to the southernmost point of South America.

It's just that the Drake Strait in later generations was discovered by Chen Dong and Deng Su first.

The two of them were in the South American continent, and they had already collected most of the things that Qian Heng wanted, and according to Deng Su's ideas, after finding most of the things that Qian Heng wanted, they had plans to return home.

However, when the ship had sailed to the vicinity of the Drake Passage, Chen Dong found that after bypassing the southernmost point of South America, there was actually a huge sea area.

So Chen Dong persuaded Deng Su to agree, and the two continued to sail forward.

However, after circumnavigating the southernmost point of South America from the Drake Passage, I sailed for a long time without seeing any continents.

Even, after seeing the icebergs on the edge of Antarctica, in the face of such a behemoth-like iceberg, the sea boat piloted by the two people avoided the icebergs far away, so that they traveled into the middle of the Atlantic Ocean.

It was in the area of the center of the ocean that two ships encountered winds and waves that they had never encountered before, and the two abandoned the ship containing food and water in order to save the supplies they had collected along the way.

Just when everyone was about to lose their lives, the only ship finally made it to the southernmost point of Africa, the Cape of Good Hope.

After seeing the land again, Deng Su and Chen Dong no longer dared to venture into the depths of the sea, so they followed the coastline all the way and finally returned to Qiongzhou.

It was also on this journey that the sweet potatoes and peppers that Qian Heng wanted, as well as the corn native to China and America, were all collected by the two.

Even, there is more than one kind of tomato, and Qian Heng is a student of agriculture and can distinguish which varieties are edible.

However, there was something that surprised Qian Heng very much, which surprised Qian Heng.

These two guys, on the way back along Africa, actually recovered a large number of coffee beans from Ethiopia.

Qiongzhou is a very suitable place for growing coffee, although there are not many areas suitable for planting coffee, but in the Great Song Dynasty, it was able to taste the coffee that was introduced to China after a thousand years, Qian Heng's mood can be imagined, and he is also extremely excited.

Qian Heng immediately arranged for someone to grind the coffee beans that the two brought back, and took a few pieces of cane sugar that had just been boiled this year.

Seeing Qian Heng enjoying the brewed coffee, Deng Su and Chen Dong were full of shock.

"Boss, this thing is really drinkable?"

Qian Heng glanced at the two of them, "Why, you still don't believe in my judgment?" ”

Deng Su hurriedly shook his head, "At the beginning, we just followed the pattern you gave us from the owner and inquired along the road, where this kind of beans is produced, the natives there also said that this thing will be eaten by cattle and sheep when grazing!" ”

Qian Heng smiled, "Don't say anything else, you can taste it!" ”21010
