Doctors are very important to human beings, even if these wizards only have some poor knowledge of herbs, but for the young country of Xia, it is also very helpful.

Wang Lang believed that as long as these wizards really regarded themselves as a part of this country, with their full support, the medical level of Xia Kingdom would definitely be able to reach a new level.

Now that sorghum liquor has been brewed, although there is no way to distill a good concentration of alcohol, but seventy or eighty degrees of liquor can also play a certain role, and as a modern man, he knows that a very powerful antibiotic, penicillin is extremely common in nature, and can be obtained from rotten fruits.

Of course, Wang Lang doesn't know how to use these penicilliums, but as long as he has a clear direction, he can use a large number of animals for experiments, or go to the northern forest to capture those cannibals for human experiments, and it is not impossible to think about one or two.

Wang Lang can only put aside the medical matter for the time being, these wizards He believes that as long as he lives in the Xia Kingdom for a long time, he will naturally be loyal to himself, and he is still a little confident in this.

In the dry season, the hot sun bakes the earth, and the crops in the fields are sluggish.

The people who have the fields, the husband and wife, carry the burden to fight the drought.

A family of five or six acres of land is a drop in the bucket under this inefficient watering.

In this case, Wang Lang estimates that the corn yield this season is definitely not as good as before, but the drought has not affected the growth of potatoes, and compared with corn, potatoes are much more vigorous.

Out of concern about the drought, Wang Lang called the Ministry of Household and the Ministry of Industry to come over.

"You've seen the weather now, and if you don't think about effective methods, there will definitely not be much corn production this year." Wang Lang said in a deep voice.

"Your Majesty, the people of the country have been working very hard to carry water and water the ground, but the weather is too hot, and the water poured down will dry up quickly, what can be done about this, if this season reaches the harvest season, and then tax the people, I am afraid that the rest will not be enough for their own food." Kong Er said worriedly.

"I still understand this, and I asked you two to come to discuss with you about the future drought fight! In the past few days, I have roughly come up with a note, if the Ministry of Industry thinks it is feasible, then the Ministry of Household will arrange for money and grain to implement the plan here as soon as possible. Wang Lang said slowly.

Since ancient times, agricultural civilization has been fighting with the sky and the earth, the damage of floods to crops is very huge, the idea of building water conservancy facilities has appeared in Wang Lang's heart for a long time, but he has been busy with other things before, and he has not taken care of this side for the time being.

Now that the Xia Kingdom has settled down and has enough manpower, it is just the right time to take advantage of this opportunity to build these things.

Under the curious gazes of the two, Wang Lang pulled out an animal skin from under the desk where he was working.

And this animal skin has been painted with a brush full of strange patterns.

Kong Er and Mu Feng, who were already literate, saw the names of the five cities on the picture, and the river in the middle had been marked as a big river.

"Your Majesty, is this our map of the Xia Kingdom?" Kong Er asked.

Wang Lang smiled and said: "It's not wrong to say it's a map, I call this thing a water conservancy and irrigation map." ”

"Irrigation map?" The two asked suspiciously.

Wang Lang pointed to the tired spiderweb-like lines on both sides of the river on the map, and said, "These lines will be dug into rivers for irrigation in the future." ”

Looking at the spiderweb-like lines on the map, thinking of the distance between Linhe and Yancheng, Mu Feng couldn't help frowning, "Your Majesty doesn't know how wide this river will be dug?" ”

"Each digging is three steps wide, and the length is about five acres of land!"

When Mu Feng heard this, his face changed, and he said, "Your Majesty, this project is too large, I'm afraid it won't be completed in a year!" ”

Wang Lang smiled, "Don't be afraid, if you can't do it in one year, you can do it in two years, and if you can't do it in two years, it will take three years, if this project is completed, not only our generation can benefit, but our children and grandchildren can also look at this thing, grow countless grains, no matter how hard it is, we must use our own strength to let this world develop according to our own wishes." ”

"I am truly ashamed of His Majesty's determination, and compared to His Majesty's foresight, it is as if my eyes can only see the size of a palm." Mu Feng smiled bitterly.

"Don't say that, you have to think more and see more in the future, as long as you can manage the Ministry of Industry well, it will also be a matter of merit in the present and in the future." Wang Lang said with a smile.

"Then Your Majesty, how should our household department cooperate!" Kong Er asked.

"Your household department has to set aside a part of the money and grain from the annual tax revenue as materials for the construction of this project, and this amount of money and grain cannot be easily used at any time, understand? However, if this year's grain production is reduced, taxes can be reduced depending on the situation, and the people of the country will not be deprived of food. Wang Lang said solemnly.

Kong Er nodded and said, "Obey the order!" ”

"Okay, you two will cooperate more in this matter in the future, and you must implement this matter as soon as possible, and step down!"

"Retire!"

The two bowed and left Wang Lang's residence.

The construction of water conservancy facilities is necessary in the agricultural era, and the huge benefits brought by irrigated agriculture are far from being comparable to those brought by the weather.

After the two left, Wang Lang repeatedly looked at the water conservancy engineering drawings he designed, this project is definitely a huge project since the establishment of the Xia Kingdom, if it can be successful, although it can not be 100% eliminated floods and droughts in the future, but it will definitely double the grain output.

A few days later, under the organization of the Ministry of Household and the Ministry of Industry, the construction of the water conservancy project began, they first started the construction from the Yancheng side, and gradually carried out along the river, the project was very complicated, and after a long construction period, Mu Feng was very bottomless, and he didn't know if he could successfully complete this task.

At the time when the Xia country was fighting drought, the expedition team had stepped out of the tribe's sphere of influence and truly penetrated into the wilderness.

All the personnel of the first expedition have become officers of the expedition corps of the military department, and they no longer do such dangerous things personally.

Today's six expeditions are composed of members from the second to the seventh expeditions, of which the members of the second expedition are the most experienced and the progress of exploration is faster.

In two months, the second expedition had left the other five expeditions far behind.

Now on a hillside, a member of the expedition took off a roll of animal skins he was carrying, laid it on the ground, looked at the direction, and marked the mountain on a rudimentary map.

"Captain, this place has been marked!"

The leader of the second expedition took the map and looked at it, nodded and said, "Keep going, we will reach the river in front before dark, and we will spend the night there today." ”
