After checking it several times and feeling that nothing was missing, Masu went straight to his father's room.

Although some nobles talked about the children and commoners mixing together, he wished that the tribe would have more warriors like his son, so he used children to play around, and people laughed at it. However, through this incident, Rosnecke discovered another talent of his son: leadership! In the past few days, I was thinking about talking to my son about whether he needed help, but I didn't expect him to come.

"Alonsi, come here," Rosnecker beckoned Ma Su over, and hugged him on his lap, kissing his face with a mess, ignoring the fact that Ma Su's little face had already turned into a bitter melon face.

"Father, I have something I want to discuss with you!" Ma Su broke free from his father's clutches and looked at him seriously and said.

Seeing his son's serious appearance, the more Ronecker looked at it, the more he liked it, and said with a smile: "What can you discuss with me?" ”

Alice, the mother on the side, said lovingly: "This child has been old recently. I've heard people say that you go out of town a lot, and when you come back, you lock yourself in your house and don't even let anyone clean your room. I went in and took a look, there were paintings all over the wall, what are you doing with Alonsi? ”

"Is there such a thing?" Rothink asked in surprise.

"Yes, father and mother, what I am going to talk about today is those paintings," Ma Su said, taking out the picture in his hand and handing it to his father.

"Boy, how did you tear your clothes like this, this is fine linen." Alice saw the origin of the "cloth" and exclaimed.

"What is this?" Rothink asked casually as he unfolded the fabric, he was looking at the map of the aqueduct, and after a moment, he looked at his son in surprise and said, "This is the map of our tribe?" Did you draw it? ”

"Father, he is not only a map of the tribe, but also a map of the irrigation layout of the canals."

"Layout of the canal irrigation, where?"

"These regular lines are," said Ma Su, pointing to the vertical and horizontal lines.

Rosneck's eyes followed Masu's fingers, and the more he looked, the more surprised he became, and he was surprised to find that these regular thin lines actually divided the tribe's territory into pieces, and then looked up and asked, "What is the use?" ”

"Divert water from the river to irrigate the fields."

Rosnek pointed to a large area and said suspiciously, "But I remember that there are no fields in these places. ”

"If the canals can be repaired and there are enough people, these places will be fields," Ma Su affirmed.

Rothink looked at the drawings carefully, his eyes became brighter and brighter, but soon they dimmed again, shook his head and said: "The water in the canal is all drawn from the river, and now the water level of the river is very low, there is no way to bring it up, the water is flowing to a lower place!" Child! However, don't be sad, I know your mind, and you're doing a great job! ”

Ma Su did not accept Rosneck's comfort, still with a confident smile on his face, and said, "The second picture can make the water flow high!" ”

Rothink was like being bitten by a mosquito, snatched another picture, looked at it seriously, looked at the schematic, and suddenly looked up and said to the subordinates outside: "Go and call Paul, be quick!" Then he looked down at his confident little son and said seriously: "Child, tell me, where did this picture come from, I want to find this person." ”

"There is no one else, it is your son, me!"

"Is it really you?" Seeing his son's serious answer, and then thinking of his son's performance in the past half a month, Rosnek said in disbelief: "How did you think of it?" No one in the tribe taught you these things, and what do the symbols on this picture mean? ”

Ma Su had a headache and made up: "I heard Paul say that there is a shortage of food in the tribe, and there have been droughts in the past two years, and my father is worried about this. So, I was thinking about how to solve the problem of water, and when I saw the small river over there, I was thinking about how to make the water flow high, and the gods were on it, and finally I thought about it. I was inspired by the grinding disc and wanted to use a human push to get water, but it seemed difficult! One day, when I saw a big tree being pushed by the current, everything worked out. ”

Alice, who was on the side, took Ma Su in her arms lovingly, kissed the top of his head, and looked proud. And Rosneck, knowing that his son wanted to invent this thing because of himself, stroked his hair lovingly and nodded repeatedly.

"When the problem of getting water was solved, I thought: With water, we can have more fields, why not? And then there are these canals! Father, in this case, will we be able to solve the problem of food? ”

"Not to mention, this time next year, we're going to be struggling with how to store food," Rothink said excitedly, imagining what the future would bring.

Then Paul came in a hurry from outside, saw his mother and brother with them, and said, "Father, are you in a hurry to summon something?" ”

"Big deal," Rothink said with a smile on his face, handing him the drawing, "It's your brother's drawing, take a look!" ”

Paul looked at Ma Su suspiciously, and looked seriously, but soon he found the crux of the problem and said excitedly: "Is this a tool to lead water to a high place?" ”

Rosnecke repeated what Masu had said earlier, and for a moment the room was filled with hope.

"Father, are we going to have a meeting right away and tell the elders about this," Paul said excitedly.

"Tell your men now!" Rothneck said.

"Wait!" Ma Su stopped, and then under the puzzled gaze of the two, he said: "Father, the use of these two things is not only for food, I have some other ideas. ”

"Hurry up."

"I hope my father doesn't take out the cart at the meeting and only talks about the construction of the canal," Mr. Masu said uncertainly.

"Aronsi, those elders will not agree without the drawings of the cylinder car, you know, the construction of the canal requires a lot of manpower and material resources. Who will do what there is no hope for, this is not good! Paul explained to his ignorant brother.

"Yes, Alonsi, your brother is right!" Rosnek nodded.
