"What's the solution?"

Everyone's eyes were focused on Tang Li, and they saw her say with a bright gaze: "Do you remember the arithmetic problem we did in the academy, knowing the speed, time, and weight of the water flow to find the distance?" ”

Zong Rui, a scumbag, has not yet understood, and Ying Huaichen Yuan Yifei and a few others have already reacted.

Yuan Yifei clenched his fist with one hand and knocked it on his palm, and said excitedly: "I know, you want to know Ning Ye's current drifting location through algorithms!" ”

Chu Zi'an hurriedly said: "Then what are you waiting for, let's calculate it quickly." ”

Bai Qiancheng showed a look of embarrassment: "But the speed of the water flow will change, we didn't measure it at that time, and the speed is different from that time, and the calculated results may not be accurate." ”

Everyone's expressions were slightly condensed, and they were not afraid of a little error, but because of the rain some time ago, the water flow grew and changed rapidly, and they couldn't use the speed at this moment to find the distance.

At this time, Tang Zhuofeng, who was paying attention to the situation on the river, listened to their conversation with a little distraction, and said loudly: "What's so difficult about this, the Metropolitan Water Division has to detect the speed of the river every day, isn't it enough to ask them for data?" ”

When the words fell, he summoned soldiers to find the capital water division.

Soon the Tsutsui Division learned of their request and immediately sent a booklet.

Tang Li and the others looked at the booklet, using the ground as paper and the wooden branch as the pen, and began to calculate.

As soon as Tang Zhuofeng finished communicating with an official, he turned his head and saw them head to head, under the light of torches, from time to time to say a few words, and then seriously write and draw on the ground.

And his Xiao Jiu seems to have become the backbone of the group, everyone surrounds her, and he has to ask her for instructions on what to do.

Tang Zhuofeng was very surprised.

If those brothers and sisters in the house saw this scene, they would probably think that there was a sister in the family who had just grown up.

It's just that this initial growth seems to have deviated from the point...... Normal orientation.

"Forget it!"

"I'm good too!"

"Wait, I haven't figured it out yet!"

Ying Huaichen, Yuan Yifei, and Chu Zi'an did not wait for Zong Rui, and reported a number in unison.

Bai Qiancheng and Zhong Linyou looked at each other and smiled: "Coincidentally, I calculated this number." ”

Zong Rui sighed: "Why am I so much worse than you?" ”

Tang Li looked at the numbers on the ground and curled his lips: "Then it seems that we all calculate the same, now let's verify whether it is correct or not." ”

She turned around and asked the officials of the Metropolitan Water Division: "Excuse me, how far is the distance from the place where the prince fell into the water to the place where the four corpses were recovered?" ”

After the chief officer of the water department asked his subordinates, he reported a number.

Yuan Yifei and Zhong Linyou high-fived: "It's the same as what we counted." ”

Ying Huaichen smiled slightly: "Then now we can calculate Ning Ye's position at this time while looking for it." ”

If Ning Yuchu hadn't left the river halfway, then he would still be going downstream, time was changing, and his position was also changing.

Chu Zi'an touched his chin and said, "We need a helper to measure the speed of water." ”

As soon as the words fell, Tang Li's eyes fell on Zhong Linyou: "Far away in the sky, close in front of you." ”

Zhong Linyou stood up and patted his chest: "Wrap it on me." ”

He had studied the rivers and boats for so long, and finally used them for a while.

Tang Li ran to Tang Zhuofeng: "Second brother, borrow a boat." ”

Tang Zhuofeng had already learned of their plan, but this was not an ordinary thing to make a fuss, the involvement was complicated, and he should not let them go to the river in public or private.

But—

Yu Gong, he has to find that kid.

Yu privately, he also wanted to find that kid.

"Tsusuiji, give them a boat."
