This was Shimizu's third time in the Land of Rain.
After the war ended, the Land of Rain was in ruins, especially since the country had been devastated during the Second Shinobi World War, and even the Daimyo had taken his treasured wealth and fled to the Fire Country's capital.
Now, even if the Daimyo returned from the Land of Fire, he wouldn't have much wealth left, and having been away from the Land of Rain for so long, he had almost lost most of his power.
And he clearly didn't have the ability to take back that power from Hanzo of the Salamander, who was a formidable figure.
However, while Hanzo was good at fighting, he was still in the exploratory stage when it came to governing the people's livelihood.
"Lord Ebizo, this is the White Sea, the only inland sea in the ninja world. Of course, some people call it White Sea Lake, considering it the largest freshwater lake in the ninja world."
On the edge of the water, Hanzo of the Salamander pointed to the endless water ahead and said to Ebizo.
Shimizu looked at the scenery where the sky met the water, with continuous drizzle, thinking that this should be the sea area where Jiraiya and Konan died in the original timeline.
He once thought that the Land of Rain was a landlocked country, so where would the sea come from? It turned out that in the real world, there really was an inland sea.
"If you want to build a canal connecting the two countries, this is the most suitable starting point," Hanzo said.
"Lord Hanzo, does Amegakure possess information on the terrain of the White Sea Lake's coastal areas and the relevant water veins?" Shimizu stepped forward and asked Hanzo.
Hanzo frowned slightly, looked at Shimizu, and then looked at Ebizo inquiringly.
Ebizo chuckled.
"Lord Hanzo, although Shimizu is my disciple, he has more say than I do on this matter."
Only then did Hanzo re-examine Shimizu, knowing that the overall plan for building the canal was made by this young man.
Even though he was the actual person in charge of this group, he was not qualified enough in many aspects.
Geographical terrain has been closely related to military affairs since ancient times, so Hanzo's actions could be considered necessary caution.
It's just that those Amegakure ninjas will definitely try to learn something about puppet techniques from Sunagakure during the process of accompanying and monitoring.
"Okay," Ebizo agreed readily.
As long as the Black Secret Technique wasn't spread, it would be difficult for other ninja villages to cultivate Jonin-level puppeteers like Sunagakure. Not to mention the White Secret Technique.
After all, a genius like Sasori, who could independently develop a Red Secret Technique, was not so easy to come by. Without the relevant knowledge system, even if they had such talent, they wouldn't be able to grow without the relevant early training.
Some other bits and pieces have actually been stolen from Sunagakure by spies from various ninja villages to varying degrees.
"Then for the next period, we'll be bothering the people of Amegakure."
With Hanzo, this key figure, settled, the subsequent matters were uniformly coordinated by Shimizu.
Fortunately, his avatar in the DC world had some experience in personnel management due to the need to manage such a large gang as the Hogg Union. With the assistance of Ishido and Miye, managing a surveying team of dozens of people was not a problem.
"There are three main sources of water for White Sea Lake. The most important is natural rainfall. The average annual rainfall in the Land of Rain is over 3,000 millimeters, while the estimated average annual rainfall of White Sea Lake is over 20,000."
"The second largest source is the Takitsubo River in the Land of Waterfall, which is the river with the largest water volume in the ninja world, and the end of the river is connected to White Sea Lake."
"Another is the river formed by the snowmelt from the high mountains located at the border of the Land of Rain and the Land of Stone and the Land of Wind…"
In a room, Shimizu and Ebizo sat on tatami mats, listening to an intelligence ninja transferred from the intelligence division reporting the information he had collected.
"The average length of the lake surface is about 210 kilometers, the width is about 50 kilometers, and the area is over 10,000 square kilometers. The depth has not yet been fully surveyed, but using the Wind Release sonar puppet made by Lord Shimizu, combined with the detection of Water Release sensory ninjas, the deepest depth found is already over 1,000 meters."
"Based on the data currently detected, the average depth of White Sea Lake is definitely over 500 meters, so we can conclude that the water storage capacity of this large lake exceeds five trillion cubic meters…"
This was the message that the intelligence ninja was reporting, which moved Ebizo.
Five trillion cubic meters of fresh water!
How long would that be enough for their Land of Wind!
While listening to the report from the intelligence ninja, Shimizu looked through the relevant terrain documents.
Lake Baikal in his previous life was also called the North Sea in ancient times and was the lake with the largest water storage capacity in that world, and the water there was even larger than the White Sea Lake here.
Of course, this White Sea Lake was already shocking enough, and it was no problem to call it an inland sea.
Shimizu was more concerned with information such as water flow rate, flow, water quality, surrounding ground height, slope, soil type, etc., and synchronized this information to his avatar in the DC world.
At this time, in the DC world, several hydraulic engineers were constructing a hydrogeological model together according to the information Shimizu told them.
Shimizu told these people that he wanted to develop a 3D sandbox game and asked them to help design part of the map.
Although they didn't know why designing a game map required doing these things, and they also had to plan a canal based on this information, Shimizu gave a lot of money, and these hired scholars put in all their effort and invested in it.
In this day and age, it was common for rich people to have some strange quirks and requirements.
"Very good, thank you all. I hope to get a complete plan within a month. I wonder if that's possible?" Shimizu, wearing a white suit, said with a smile to the hydraulic engineering experts.
"Mr. Wot, the data you provided is very detailed. After we go back, we will use computer-aided mathematical modeling software to assist in the work, and we expect to complete the plan within twenty days," the leading bald white scholar said to Shimizu, pushing his glasses.
"Professor Jeff, I believe in your professional abilities." Shaking hands with the experts and having his assistant send them away, Shimizu turned his gaze to a bodyguard from the League of Assassins.
He had another guest to see.
