Several people discussed it one after another, and finally came up with a relatively appropriate solution.

Four people were already the maximum number who knew this secret, and it was absolutely impossible to let one more person know it, so everyone agreed that several people would take turns testing the conditions for triggering the white stone.

Everyone wrote down the physical factors that could trigger the repulsive ability, and then carried out the experiments one by one. During the experiment, one volunteer touched the white stone, and the other three assisted.

"But I don't have the white stone now. When I came back from the last expedition, you all said that the white stone was a very precious thing, and I only have that small piece in my hand." Su Nian became worried.

"Bai Shi is not a problem, I still have some on hand," Sha Qilin patted his chest and took the responsibility of finding resources.

"It's this experiment to trigger Bai Shi's ability that is quite difficult. There are only four of us. What if after the test, all four of us are sent away?" Chu Beichen raised a fatal question at this critical moment.

Everyone fell into deep thought. They had never heard of any scientific experiment being successful after just one try.

According to Chu Beichen's statement, everyone felt that although it might not necessarily be so unlucky, what if it happened?

"So our idea is still not safe enough!" Han Qing sighed again. He is the oldest among the group and now has become the leader of the four-member team.

"Uncle, I have a good way to keep safe, but you have to let me join!" A still childish voice sounded.

"Kang Kang! When did you come?" Chu Beichen opened his eyes wide in surprise. You know, in order to prevent anyone from eavesdropping on the terrace, he had thoroughly searched the environment of the terrace in advance and then locked all the doors leading to the terrace.

Kang Kang smiled slightly and pointed at a bamboo dragonfly on the grape trellis. "This bamboo dragonfly is a robot I made. Through it, I can see everything going on on the terrace."

"And Dad, the door to the terrace has a combination lock, right? Your combination is so old-fashioned, I got it right in one try!"

If you are not as skilled as others, you will be bullied. Chu Beichen, as a father, feels very embarrassed because his son has completely crushed him in terms of IQ.

Su Nian quickly pulled Kang Kang aside and said, "Kang Kang, it's wrong to eavesdrop on adults' conversations. Besides, you are still young and shouldn't get involved in such things!"

Kang Kang scratched his head. "I'm a little young, but I don't think age has anything to do with this matter. At least I have a good idea for testing Bai Shi!"

As an uncle, Han Qing loved his nephew the most. He pulled Kang Kang in front of him and said, "Good nephew, your uncle believes in you. Come, tell us what good ideas you have!"

Kang Kang nodded seriously and said like a little adult, "If you want to test the white stone, the conditions you can provide are nothing more than the physical changes of sound, light, cold and heat."

"There are some other reactions that don't require human operation. I have many robots that can adapt to this job!"

Sha Qilin coughed. "Kang Kang, you really put me to shame. Honestly, few labs can set up such experimental conditions right now. You just mentioned a lot of robots..."

Kang Kang wasn't in a hurry at all. He didn't even use the remote control, but waved his hand casually. "Okay, I know you won't believe me unless I show you something practical. Come out, it's time to show the adults what we're made of!"
