The room at the east door was extremely simple, except for a wooden bed, there was a blackboard that occupied the entire wall, and the blackboard was full of dense patterns and some ugly writing.

The east gate sat on a tripod, and by the light of the fire, he wrote and drew on the blackboard very seriously.

Paper is an incomparably precious thing, and the little bit of the east gate simply can't withstand such a large amount of drawing work, and the reusable blackboard has become the only existence that accompanies him day and night.

It is a very happy thing to devote yourself to the career you love.

Yang Hao sometimes envies these pure researchers, no matter what era they are, such talents are the key to promoting the progress of human civilization.

It had been a long time since he had scolded the thief God, because he felt that it was definitely a gift from God that so many talents could emerge in the Qi Kingdom.

Otherwise, with his ability alone, it is estimated that he is still struggling to support in the melee of the city-state.

Yang Hao thought in his heart that the most correct thing he had done in his life was to put himself in the right position, and he had never underestimated the wisdom of human beings in ancient times from the beginning.

A person's strength is always limited, he is not an all-powerful god, and he does not have an incomparably anti-heaven artifact when he travels, nor does he carry a huge amount of materials with him, just like Doraemon, he can conjure up whatever he wants.

To the extent he is today, he has reached the limit of what an ordinary person can do.

In July of the 14th year of Hongwu, when the first batch of edible radishes was harvested, Shixi, who had sailed for a month, led the small test ship and returned to the port of Chang'an.

After the inspection of the Ministry of Industry and the information brought back by Shixi, the first ship in Qi that meets the requirements of ocean-going navigation officially passed the test.

Yang Hao, who was excited, immediately rewarded everyone who participated in the research of the ship, and made a great contribution to the meritorious ones.

And named this first test ship, Hongmeng.

With the perfect performance of the Hongmeng, shortly after the return of Stony Creek, Chang'an Shipyard and Penglai Shipyard immediately started work in full force.

The materials for the ship have already been prepared, just waiting for the ship to be launched across the ocean.

And the imperial court also officially began to recruit crews.

Since it is a long voyage to the sea, it is full of unknown dangers.

The recruitment of the imperial court was not smooth, and people like Shi Xi with a strong spirit of exploration were a minority in the Qi Kingdom after all.

For ordinary people, it is not good to stay in such a peaceful and safe environment in Qi Country, and they have to go to the sea of cannibalism like death, this is not a disease.

Shi Xi saw this in his eyes and was anxious in his heart.

The recruitment work lasted for half a month, and there were less than two people in Chang'an City who were willing to sign up.

There are 100,000 people living in Chang'an City, and this disparity in proportion makes Yang Hao not know what to say.

But if you use coercive means to force others to be sailors, Yang Hao doesn't want to do such a domineering thing.

After thinking about it, Yang Hao had a good idea.

It is understandable that people with a stable life are reluctant to take risks.

Therefore, Yang Hao changed his thinking.

Compared with the surrounding areas of Chang'an City, the living standards of the people in the state capital, far from the political center, are still at a very low level.

For these difficult areas, he believes that there must be people who are willing to die for them under the great reward.

In order to be able to form an expedition as soon as possible, Yang Haoming's herald distributed the official documents recruiting sailors to the border state capital area as quickly as possible.

All he could do was wait patiently.

It's just that Yang Hao was not idle while waiting, and let Shi Xi and those selected sailors have a fully enclosed sailing skill learning.

For example, how to locate on the sea, how to draw nautical charts, write logbooks, record ocean currents and other related skills.

To this end, Yang Hao sacrificed a navigation artifact and a beautifully shaped compass.

This compass is made of a hard-won magnet, and the number of the entire Qi country is less than three, which can be described as a priceless artifact.

Stony Brook looked at the hands that were turning in the plate, and immediately understood the importance of this thing for navigation.

Since the day he got the compass, this thing has never left Stony Brook's side again, even if he sleeps, he has to keep it within his reach, and in his heart this thing is even more than his own life.

For the upcoming voyage, Yang Hao made as many complete preparations as possible.

He sorted out all the relevant nautical knowledge in his mind, whether it was useful or useless, or hearsay, and instilled it in these crew members.

From this year onwards, Yang Hao ordered the household department to make as many fruits as possible into sealed cans.

Among the nautical knowledge that Yang Hao knows, the most terrible thing about ocean voyages is the lack of vitamins for a long time.

As the first person to explore the world in later generations, Magellan was shot by a poisoned arrow in a battle with the local natives, and died in a foreign land.

But then Captain Elcano continued to lead the fleet, but one by one their crew began to fall.

The nightmare scurvy of the Age of Discovery led to the death of countless crew members, and the terrible scurvy raged in the fleet like a plague, with countless crew members having swollen gums, swollen legs, and tendon atrophy, and wordless horror permeating the entire fleet.

Yang Hao naturally would not ignore such an important matter.

And he also knew what the cause of scurvy was, and his purpose was to get the fleet back from the American continent as quickly as possible, and if the crew fell short because of his own negligence during the long voyage, he wanted to grab the ground with his head.

The production of cans is not complicated, as long as they are sterilized at high temperature and sealed and preserved, at least they can give the crew a certain amount of vitamin C as a supplement before the cans are completely destroyed.

In the atmosphere of large-scale production in the whole country, at the beginning of August of the 14th year of Hongwu, after more than two months of calm in the Academy of Sciences, another commendable thing happened.

A person who had no sense of existence before was actually canonized as an official researcher by Yang Hao.

And this person is the prisoner of Dongmen who has been engaged in bridge research for a year.

Within a year, Dongmen did not achieve the impossible bridge that Yang Hao once said, but he used his own efforts and existing materials and technology to make a good design.

Although the bridge he designed can only be like a child's house compared with the professional bridge designers of later generations.

But after Yang Hao saw it, he felt that it was very feasible and could theoretically meet the needs of laying rails.

As long as the bridge is built, it can immediately save the time of loading and transshipment, which is of incomparable importance to the flow of materials between the north and the south, and can be said to be the most important alternative method before the emergence of the north-south Grand Canal.
