Chapter 172

Ying Wuji frowned, thinking.

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

"Under the fish?"

When Xia Yuan heard Luo Chuan's words, he was also puzzled, not understanding why he should aim below the fish.

However, based on the boss's insight, it should not be wrong.

He chose to trust the boss!

Xia Yuan held his breath and stared at the water.

By coincidence, a fish swam past in front of him.

Good chance!

Xia Yuan's eyes focused, his arm muscles tensed, and the spear burst into the water!

The location of his attack this time was below the fish!

Huh!

Unlike before, this attack directly pierced the fish!

Xia Yuan picked up the spear and looked at the fish still wriggling on it, a little surprised.

"It really worked..."

Xia Yuan came to the shore of the lake and put his spear on the ground.

He looked at Luochuan and asked puzzledly, "Boss, why did attacking below the fish work? I clearly aimed at the fish before, but I couldn't hit it?"

This question was on everyone's mind.

Why was that?

Looking at those eyes full of curiosity, Luochuan felt he had to share the charm of physics with them!

The science of another world, it is up to Luochuan to carry forward!

"Do you know why we can see things?"

Luochuan thought for a moment and raised a question.

"It's because we have eyes!" Gu Yunxi replied excitedly, "Some monsters don't have eyes. They perceive the environment by mental power!"

The rest of the students gritted their teeth.

Hateful!

Such a simple question was actually preempted!

Contrary to Gu Yunxi's expectation, Luochuan shook his head.

Obviously, her answer was wrong!

"Boss, what did I say wrong?" Gu Yunxi was a little angry.

"I think it's because of the light."

Xia Yuan touched his chin and then gave this answer.

Luochuan nodded, "That's right."

A smile appeared at the corner of Xia Yuan's mouth.

That was the smile of a winner.

Gu Yunxi was puzzled, "Why?"

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

Gu Yunxi's expression froze.

It seems... this is indeed the truth...

"But…"

Gu Yunxi wanted to refute, but was held back by her best friend Jiang Wanshang.

Jiang Wanshang persuaded in a low voice, "Yunxi, it's alright, you don't know the boss's strength and realm. He should be correct in everything he says."

Gu Yunxi gave an "Oh" and did not refute.

She was not the kind of unreasonable girl.

At this time, Luochuan's voice sounded again.

The two quickly recovered and listened carefully.

These things Luochuan said sounded quite novel to them.

This was a new kind of knowledge different from cultivation!

Luochuan continued, "It is because there is light that we can see all things in the world. Just like mirrors and lakes, light falls on them, is reflected, and falls into our eyes, creating images."

Everyone nodded in agreement. Luochuan's words were easy to understand, and the examples he cited were relatable.

Luochuan went on to say, "Similarly, when light passes through certain substances, its path changes. This phenomenon is called refraction."

At this point, some people struggled to understand.

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

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

Everyone followed.

"Look." Luochuan inserted the branch into the water. "Does the branch seem to be bent?"

They all observed the branch in the water and noticed that it appeared bent.

"It's because of refraction. The light changes direction as it moves from air to water, making the branch look bent."

The students marveled at this new understanding.
