Chapter 177

Should be endless frown, thinking.

He knew that since the boss said so, there must be a corresponding reason.

"Under the fish?"

Xia yuan heard Luochuan's words, he also did not understand why to attack that position.

But with the boss's insight, it should not be wrong.

He chose to trust the boss!

Xia yuan held his breath and gazed at the water.

Coincidentally, a fish swam past him.

Good chance!

Xia yuan's eyes coagulated, his arm muscle strength broke out, and his spear even broke into the air!

This time, the position of his attack is under the fish!

Whew!

Unlike before, this attack will directly pierce the fishbone!

Xia yuan picked up the spear and looked at the fish which was still solemn. He was surprised.

"Unexpectedly, I really hit..."

Xia yuan came to the lake and put his spear on the ground.

He looked at Luochuan, puzzled asked: "boss, why attack the fish below can hit, I clearly aim at the fish, but the results can not attack?"

This problem is also a puzzle in everyone's mind.

Why?

Looking at that pair of eyes full of curiosity, Luochuan felt that it was necessary for him to popularize the charm of physics with them!

The science of the different world will be carried forward by Luochuan!

"Do you know why we can see things?"

Luochuan thought slightly and raised a question.

"Because we have eyes!" Gu Yunxi replied excitedly, "some monsters don't have eyes. They rely on mental power to perceive the environment."

The rest of the students gritted their teeth.

Damn it!

Such a simple question, unexpectedly was preempted!

Beyond Gu Yunxi's expectation, Luochuan shook his head.

Obviously, her answer is wrong!

"Boss, where am I wrong?" Gu Yunxi was a little angry.

"I feel, because of the light."

Xia yuan touched his chin and gave such an answer.

Luochuan nodded: "yes."

Xia yuan's mouth lifted a smile.

It was the winner's smile.

Gu Yunxi did not understand: "why?"

"In an environment without light, even if you have eyes, can you see things?" Luochuan explained

Gu Yunxi's expression was stagnant.

It seems that This is the truth

"But..."

Gu Yunxi also wanted to refute two sentences, and was pulled by her best friend Jiang Wanshang.

Jiang Wanshang low voice advised: "Yunxi, OK, boss strength and realm you don't know, he said things should be right."

Gu Yunxi "Oh" a, did not refute again.

She is not the kind of unreasonable girl.

At this time, Luochuan's voice sounded again.

The two quickly returned to their senses and listened carefully.

Luochuan said these things, they all feel quite novel.

This is a new knowledge which is different from practice!

Luochuan: "it is because of the light that we can see everything in the world. It's like a mirror or a lake, where light falls on it, is reflected off, and falls in our eyes, so there is an image. "

A nod of approval.

Luochuan's words are easy to understand, and the examples are all attempts in life.

"Similarly, the propagation of light, after passing through some substances, will change its path. This phenomenon is called refraction," Luochuan added

At this point, some people don't understand.

Luochuan knows that practice is the only criterion for testing truth.

He picked up a fairly straight branch and went to the lake.

The crowd followed.

"You see." Luochuan inserted the branch into the water, "does the branch look bent?"
