"I understand, what you mean is that every time we test, we can change a circle?" Lan Zhize looked stunned.

Du Gang shrugged and said, "It's almost the same. You can understand it as a judgment question. Every time you test, you can judge whether there is a son of destiny in this circle. If not, you can change to a place to test. If there is, you can enter the third stage..."

"I see!"

Everyone suddenly realized and showed admiration.

"ox!"

"That's amazing!"

This time, the four of them were convinced.

At the beginning, Du Gang was wondering whether he really had the ability to lock in the son of destiny, but now, there is no doubt at all.

"Is this equivalent to finding someone by enclosing land?"

Lan Zhize named Du Gang's method with a smile, "Draw a piece of land with Du Gang's red line and circle it. The four of us are responsible for the test. After the test, the son of destiny was in the field. If it was not tested, then change to another piece of land..."

Du Gang smiled and said, "Not only that, what I just drew was just for your understanding. In fact, if you don't use so many circles, the circle we use next to find someone is actually a straight line!"

“???”

The four of them just felt that they understood something, but when they heard this, they were confused again.

Du Gang became interested and began to tell everyone: "We assume that the position of the son of destiny will not change!"

"In fact, the position of the son of destiny should not change in the short term, because we will measure it once every hour..."

"His position remains unchanged, so the direction we measured is certain, and they are all fixed on a straight line..."

As he said that, he drew a straight line in the center of a row of circles on the map, connecting seven or eight red circles together.

“Fixed?”

This time, everyone still couldn't make a turn and couldn't understand it.

“The reason why it is fixed…”

Du Gang thought that they had not learned basic mathematics, nor did they say it in a complicated way, but pondered for two seconds. When he looked up, his eyes suddenly lit up and he smiled and said, "Let's do this, you should imagine the sun as the son of destiny now. His position is fixed. In this way, what we have to do is to keep approaching him, draw red heart circles, and ask you to do tests, all for progress..."

"And once the circle we draw exceeds the sun, then the fixed direction will change, which also means that we have the specific position of the circle and can conduct the third stage of testing..."

"I understand, I understand!"

This time, Kou Yingwu was the first to clamor.

He looked excited, "I understand, just do what you said, Du Gang, you are such a genius. With this method, we will definitely be able to find the son of destiny..."

As he said that, he looked up at the sun and nodded, "The time is almost over now, it's almost time to reveal it. It's time for us to start the next stage of testing..."

Then, he ran towards the north with a proud pride.

Kou Yingwu felt bitter inside.

His grandma, if I stay there, I feel like I am mentally retarded.

He basically didn't understand what Du Gang said, but he just felt that he seemed to be right!

"ah?"

Looking at his back, Du Gang was speechless.

Does this guy really understand?

Going directly north, this is the direction I tested before!

He shouted helplessly: "Wait, you're in the wrong direction!"

"Now, we are going to advance along the northwest central line. When we reach the center of the circle, I will assign you directions..."

When Lan Zhize heard this, he was originally willing to show off his pride. He stopped what he had just said.

Because, like Kou Yingwu, he thought that the direction he wanted to test was still the West...

Tao Xuanzhu seemed to have some understanding. At this moment, she looked at Du Gang with anticipation and asked: "What do you mean is that we used to test according to the direction of the mainland, but now, we need to test according to the direction of the circle you draw?"

"That's right!"
