Seeing Yang Hao's expression as if he was eating people, several officials were startled.

"It should be true."

The man said with some fear.

Yang Hao immediately laughed wildly when he heard this.

"Good! Good! Good! God help me! God help me! ”

Several people not only looked at each other, but they didn't know why Yang Hao was so excited because it was just a rather strange thing.

"If you find out where the man in that place is, bring him quickly."

"Chief, that man is on rest this day, and he should be in the city at this moment."

Yang Hao nodded and said, "Go and send someone to find it now, no!" Never mind! I will be in the city now, and you will bring him to me in the palace at once. ”

After speaking, he ignored the stunned few people, and returned to the city excitedly with the guards.

Not long after Yang Hao returned to the palace, officials from the Ministry of Industry brought a soldier over.

Yang Hao was not interested in asking his origin, and asked directly: "You have really seen the place where there is bird droppings." ”

Being able to be received by Yang Hao in person, the soldier's already nervous brain was blank at the moment, and he didn't hear what Yang Hao was saying at all, just kneeling there on one knee.

Yang Hao frowned and said, "Fetch a glass of water for this soldier." ”

When the maid on the side heard this, she hurriedly got some water from the pottery and sent it to the soldier.

The soldier shuddered and took the glass of water, and drank it dry to feel much better.

After Yang Hao asked him to sit down, he asked again.

The soldier hurriedly said: "Back to the leader, my subordinates have indeed seen it." ”

Yang Hao's heart was relieved when he heard this, and said, "Tell me in detail." ”

The soldier wiped the sweat from his forehead and said, "On that day, a few of our subordinates were ordered to go downstream to survey the river, and two days later, we came to a large lake, and in the lake was the land of guano.

When we saw that there were a lot of birds over there, we thought it would be good to go and catch a few to eat, or to find some eggs.

But when we got there, we found the stench so foul that the ground was full of bird droppings, making it difficult to walk, and we saw that the lake was too big for the canoe to walk in it, so we went ashore and returned along the bank.

”

Yang Hao's heart was beating extremely fast, and he once again confirmed the accuracy of this news, he thought that he would be able to deal with it calmly, but he couldn't control his excitement at all.

The temptation of guano is too great for other tribes to avoid, but he knows that as long as the guano is mined back, this year's grain production will definitely increase a lot.

Deep cultivation, water irrigation, if you add this natural compound fertilizer, damn it, Yang Hao doesn't know what words to use to describe it.

In addition to the absence of pesticides and high-yielding seeds, the agricultural conditions in Daqi are almost perfect.

As long as he didn't make fatal mistakes in the later stage, thinking about the possible yield of an acre of land, the corners of Yang Hao's mouth almost left saliva.

"It's gone, it's been issued! Damn, it must be mined, and if anyone dares to stop Lao Tzu, I'll fucking screw your head off! ”

Yang Hao's expression was a little hideous.

When the soldier saw Yang Hao's uncertain expression, he secretly beat a drum in his heart, wondering if he had said something wrong.

But soon Yang Hao's voice sounded again, and said: "You step back first, I will send someone to find you after a while, you take turns off today, I allow you to rest for two more days, report the names of the soldiers who were with you that day, and no one will reward three copper coins." ”

When the soldier heard this, he was immediately overjoyed, and hurriedly bowed: "Subordinate Leader Xie, Leader Xie!" ”

Yang Hao waved his hand and motioned for the soldiers to stand back.

After the soldiers left, Yang Hao paced back and forth in the palace excitedly.

"Guano and guano and guano canoes are definitely not going to work, you have to use boats.

No, the shipbuilding of the dog day is too slow, and it is cold to wait for the ship to play with shit.

”

Yang Hao stopped and clapped his fists.

"I can only use canoes, so I can't manage so much."

The excited Yang Hao hurriedly came to the desk and pushed the sundries aside.

I started thinking about the construction of the raft.

Although guano can be transported back by land, there is certainly no time to save manpower by water.

However, although the raft is easy to do, Yang Hao still has to consider how to make the raft return, after all, it is not an easy thing to go upstream.

All he could think of was sails and slendermen.

However, the manpower consumed by the slender man is too large, and now the Daqi tribe lacks everything, and the population is even more short.

If the slender man is used, then the embankment will not be built or planted, and all the fiber will be pulled in the past, which is certainly unrealistic.

It's just that Yang Hao, as a person who grew up inland, has only seen sailboats on TV, and it is simple to make a raft with sails, but how to drive it is really a troublesome thing.

Yang Hao roughly designed a simple sail raft diagram, took his own set of carpentry tools, left the palace, came to the courtyard to find some finger-thick branches, ready to make a model.

The palace maids have long been surprised by some of Yang Hao's special hobbies.

Serving beside him, he watched curiously as Yang Hao fiddled with this pile of dry firewood.

But what made Yang Hao depressed was that as soon as the materials of the raft model were processed, the sky darkened.

Yang Hao had no choice but to let people light a bonfire and continue his modeling career by the light of the fire.

In order to grow more food, Yang Hao also worked hard, fighting until the second half of the night, and finally made the sail raft.

Yang Hao looked at his works with satisfaction, and couldn't wait to try the effect of sails.

It's just that looking up at the moon in the sky and the Milky Way across the sky, I can only temporarily dispel the restlessness in my heart.

Holding the treasure in his hand, he returned to the dormitory with his own achievements.

Fell asleep on the bed.

Yang Hao, who had something in his heart, got up early the next morning, hurriedly made a bowl of millet porridge, and ate an egg.

didn't even bother to wash his face, and went out of the palace gate with a mold.

In order to experiment with the characteristics of the sail, Yang Hao found a large clay jar, filled it with water, and put the raft model into it.

In order to simulate the wind, Yang Hao asked several maids to gently incite in one direction with a fan that was hurriedly made.

The raft moved, but the tank was too small to get exact test data.

Seeing this, Yang Hao asked the maid to stop, called a few guards, and found an open space for them to dig a ditch here.

With a bronze shovel and a bronze pickaxe, it was not difficult to dig a ditch one meter wide and about twenty centimeters deep.

In less than an hour, a straight ditch was completed.

Fill it with water and experiment again.

This time, with a large enough test site, Yang Hao's test went smoothly.

Using the wind made by manpower, Yang Hao recorded the wind in all directions, the angle of the sail, and the image of the raft in detail.

Looking at the data on the bamboo slips, Yang Hao felt that he was simply the Einstein of this era, a Newton-like figure.

I admired myself in my heart.
