The western suburbs of Chang'an City.

The war in the south did not affect Yang Hao's mood at this time.

Today is a memorable day for him to make fun of Daqi, and the rumbling cannons resounded through the fields of the western suburbs.

After several years of unremitting efforts, a large number of craftsmen, and countless sums of money, the state of Qi finally applied gunpowder to the military field in a real sense.

Although the heavy artillery could only be fired at a distance of about 200 meters, the workmanship was extremely crude.

There was even a cannon that exploded, but this did not hinder Yang Hao's mood of cheering in the slightest.

How important artillery is for a country, how unclear he is.

Although this kind of artillery cannot be applied to actual combat at present, at least the projectile has been successfully set out, which proves that its research direction is correct.

As long as the production process is further improved, he believes that in the near future, artillery will be equipped on a large scale in all armies of the Qi State.

Sometimes, totalitarian rule is far more efficient than democracy, and there are not so many things that go wrong.

Although officials at all levels lack capacity, they are able to implement the policies they have formulated well.

This is due to Yang Hao's prestige comparable to that of the god of Qi.

Under this prestige, no constraints exist, and the only goal is to move forward, forward, at any cost.

What money is, it's a bunch of shit, it doesn't need to be in the right place, what's the use of having more money.

Qi is not a commercial society, as an agricultural civilization, as long as the basic materials of food and cloth can be guaranteed, other pleasures are trivial, and they are no longer within the scope of Yang Hao's consideration.

The country of Qi, which has developed for nearly ten years, is a relatively deformed society, with an extremely shallow cultural heritage, and under the influence of Yang Hao, there is no soil for art to breed at all.

Music, painting, and other things that cultivate sentiment can be eaten as food.

Even the art troupe created by Yang Hao is an extremely embarrassing existence.

In the past ten years, there have been less than five fingers of new dramas, and literary and artistic workers can only live by holding on to their old books, and their status is higher than that of savages.

Wei said excitedly: "King, only one of these three artillery pieces is explosive, it is really blessed by the ancestors, I think it won't be long before this artillery can exert its power on the battlefield." ”

Yang Hao nodded and said: "Firearms are sharp, they will definitely dominate the battlefield in the future, only artillery is not enough, and after perfecting the artillery casting process, you must start to develop muskets."

”

Wei sighed and said, "The Ministry of Industry has also tried to make a cannon that can be held by one person, but its power is really not suitable for use in the army. ”

"It doesn't matter, as long as you continue to research, you will always find a way, I Daqi has too much money to train an archer, and it can't be used as the main force without a few years of work, if the musket can shoot a projectile of about 100 meters, even a child can kill a strong man, so that my Daqi can be peaceful forever."

Wei smiled bitterly, Yang Hao's request, judging from the current Qi country's technology, is really too high.

Yang Hao smiled and said: "You don't need to have any pressure, this matter is not enough, there is no strong enemy around our country now, but improving the power of weapons is a policy to secure the country, and it must not be interrupted." ”

"King Shengming!"

Yang Hao said: "Whether the saint is holy or not is a lie, the country of Qi is not my own country of Qi, for more than ten years, how much sweat have you paid for this great country, this king understands in his heart that you are the builder of this country." ”

"Don't dare!"

"What if the minister can pay some hard work for the king and the country of Qi, as long as the Great Qi is strong and the people live in peace, it is enough."

Yang Hao nodded and looked at Song Shilang behind the guard.

"Song Aiqing handed over the fold the day before yesterday, this king has already read it, and the idea is very good, but there are some places that need to be improved."

When Song Shilang heard this, he hurriedly said: "Listen to the king's teachings!" ”

"You say that there is a star in this sky that does not change all year round, and that this star can be used to show the way for the voyage fleet, and this king thinks that this idea is correct, but it is not perfect.

In the past few days, this king has followed your ideas and watched the starry sky at night, which has been quite rewarding.

The world we live in is a huge sphere, and the sphere is free to number, no matter how large its essence cannot be changed.

If a line is drawn horizontally and vertically on the sphere, the point at which the two lines intersect is the only one.

The king called the horizontal line latitude, and the vertical line was the precision.

Whether at sea or on land, as long as you can measure its guards, you can determine your position.

”

Yang Hao always has some unique ideas, which has become the subconscious common sense of everyone.

After finishing speaking, the officials of the Ministry of Industry did not think about whether this idea was wrong, and instinctively thought that since Yang Hao had come up with this method, it would definitely work.

But when they understood it according to Yang Hao's train of thought, they always felt that there were some things that were difficult to understand.

"King, this world is so big, even if it is spherical, how can we measure the latitude and longitude, after all, we are too small compared to this world."

Hearing this, Yang Hao immediately laughed.

"It seems that you have been an official for too long over the years, and you have lost a lot of arithmetic knowledge."

Everyone was a little confused, not knowing what Yang Hao meant.

Seeing this, Yang Hao squatted on the ground regardless of the image, and said: "Everything in this world has a law to be found, if you observe carefully, you will find that the sun on our heads, the sunrise position in winter is south-east, and the sunset position is south-west; In summer, the sunrise position is north-east and the sunset position is north-west; Around the spring and autumn equinoxes, sunrise is due east and sunset is due west.

Speaking of which, you should be able to imagine that the world we live in is always revolving around the sun.

The vernal and autumnal equinoxes, on the other hand, mean that the sun's rays shine directly in the middle of the sphere.

Knowing this, we can use shadows and trigonometric functions to roughly measure the latitude and longitude of a location.

It's just that the specific calculation of this king has not yet been communicated, but the direction should be correct.

The rest is up to you.

”

As a good thrower, the king of Qi naturally threw this astronomical problem to these ministers, not that he didn't want to do it, but he had no choice but to return most of his knowledge to the teacher.

As for the sextant, he had never seen it, even if he was given time to study it.

But he is the king of a country, and it is impossible not to dare to do anything, and to engage in these scientific studies every day.

This is a pain for these ministers of the Ministry of Industry, what Yang Hao just said is to explain from the perspective of God, for officials who have not seen a model of the solar system, the amount of information is too great, and for a while they can understand that a three-percent is already talented.
