That’s how the so-called Zimmer River actually takes shape!
If the daughter and mother rivers are both in exactly the same channel, then the discovery of the daughter river will inevitably lead to the discovery of the mother river, and the enemy, by adopting such means as cutting off the flow, will also completely cut off the source of the mother river.
So, in that case, the stratagem looks good, but it will be very badly used.
But if the sub-mother river is not out of one channel, then the construction may not reach the time and labour-saving side of the essential sub-mother river.
“The sub-mother river has to be well designed, so it can naturally and skilfully circumvent this problem.”
Han Sanqian’s idea for the mother river was to directly dig out a huge concave shape as the body first, and of course, this concave was an inverted trapezoid.
That is, the way it was wide at the top and narrow at the bottom.
“On top of the earth, we have a place that used to be hit by flooding all the time, that place
was originally a fertile land, but the floods caused it to be very dry at times, and at other times it was attacked by floods.”
“But the ancestors were very clever, and they came up with a method of curing the water, so that that place, from then on, had favourable winds and rains. This thing, called the weir, when the rainy season comes, the weir will divert the water, the pressure of the water will be drained out, so that the flood no longer rages, when the drought comes, the weir will likewise divert the water, the water in the river will be irrigated to the relatively dry place, so as to ensure that this piece of plains land, there is water at all times.”
“Though that weir was used to treat water, we ourselves should learn to learn by example.”
“Therefore, I intend to use the weir in our Zimu River.”
The old Dragon King was a bit confused by what he heard, he was a titular king of the water, but at this moment, he was being used by Han Sanqian on water healing
face crazy lessons.
However, he didn’t have the slightest bit of resistance or aversion, instead, he was learning with an open mind.
“Our inlet and the neighbouring zone, as wide as you can expand it for me.”
“To give you an idea, I’ll give you a figure.”
“For example, at the opening, we set a width of about ten metres, so this river goes all the way downstream.”
“But in the process, I ask that the banks of this river begin to shrink.”
“It can be nine metres, eight metres, or even directly shrink to one or two metres after a certain distance.”
The old Dragon King shook his head, still not quite understanding, wasn’t this just simply fixing a river from wide to narrow, and what did it have to do with any kind of sub-mother river?
Han Sanqian had known that he would have such a reflection, picking up a tree branch and drawing a divination-like character on the ground.
In fact, the river
became narrower, it didn’t mean that the entire river really became narrower.
Han Sanqian just started to leave an embankment in the centre of the river to divert the flow.
It looked like the main river was only about four metres wide, but in reality, the real width of the entire river was still ten metres, only that embankment had been divided by another six metres to form another river.
In other words, the river was gradually split in two.
“It’s just that the other river that has been divided into two, we’ve divided to the other side as soon as we leaned on the riverbank, but instead, it’s hidden under the ground.”
The old Dragon King frowned deeply when he heard this, but soon he came to a sudden realisation.
“I see, the so-called Zi Mu River is splitting the river in two. If this is the case, the amount of work we have to do has not actually increased, because from beginning to end, all we have built are three river channels
.”
“It’s just that, these three river channels were secretly divided into six by us.”
Han Sanqian smiled and nodded, “Not bad, exactly.”
“This method is wonderful, this …… This really won’t increase our workload, on the contrary, to a certain extent it also reduces our workload by quite a bit.”
Because originally it might be a direct ten metres distance, which needs to be dug directly without, but, because now there needs to be a riverbank in the middle, the middle part doesn’t even need to be dug yet, in this way, this isn’t solving the time and cost, and what is it?
Thinking of this, the old Dragon King finally revealed a smile.
Han Sanqian gently smiled, “No need to be happy so early, we although this solution is theoretically feasible now, there are still some pain points that need to be resolved in practice.”
“Mr Han, what other problems do we need to solve?”
