Deep Palace Pet Peach Blossom Flawless

Lan Qingwu smiled faintly: "How difficult is that! Chu Ming can just go for it. Do you still remember what the Queen Mother taught you? But the Queen Mother doesn't want to gain their approval, as long as we can live in peace."

The Sixth Prince put down the teacup in his hand and said, "Of course I remember. Mother once said that practice is the only criterion for testing truth. If they don't believe me, I will show them!"

The Seventh Prince quickly replied, "Mother, my brother has already started preparing, and we've even asked our Second Brother for help!"

Lan Qingwu nodded: "There's plenty of time for spring hunting, so it's good to find something else to do!"

It turned out that before the Sixth Prince came to pay his respects to Lan Qingwu, a round of debate had already taken place in the emperor's meeting.

The cause was simple: the Sixth Prince and his senior brother had been privately discussing the color of the sea. Influenced by Lan Qingwu, the Sixth Prince naturally knew that the color of the sea was affected by the refraction of sunlight and the depth of the sea. He then argued with another disciple of the great Confucian scholar Yuan Zhiqing. Unexpectedly, that senior brother, Xie Yiqian, was a stubborn scholar. In the central tent, Xie Yiqian asked his master in front of Emperor Shenwu, Yuan Zhiqing, and a group of foreign envoys: "Sir, I really don't understand what my junior brother said. The sea looks blue, isn't it because it is sea water? The water in other lakes is clear and transparent, but why do you say that all water is transparent no matter what kind?"

Although Yuan Zhiqing was a man of profound knowledge and extensive reading, he was skeptical of the Sixth Prince's words. However, in front of the envoys from several countries, he couldn't afford to refute his young disciple. He knew the Emperor Shenwu's intentions; his young disciple was already a potential heir to the throne.

Even so, the magic eagle also shouted: "Isn't this something that can be seen with the naked eye? This is also worth arguing about!"

The Sixth Prince said, "The color of seawater is primarily determined by the scattering effect of light, suspended matter in the seawater, depth, and other factors. The ocean we normally see appears blue or green. The first is the scattering effect of light. Sunlight is composed of seven colors: red, orange, yellow, green, cyan, blue, and violet, each with a different wavelength. When sunlight strikes the ocean, the longer-wavelength red and orange light is absorbed more by water molecules, while the shorter-wavelength blue and green light is more easily reflected and scattered. Therefore, the ocean we see mostly appears in these colors. Because the human eye is insensitive to violet light, even if some violet light is reflected back, it is difficult for us to perceive it."

Then there's the suspended matter in the seawater. Nearshore water contains more suspended particles, such as plankton, algae, and sediment. These particles can affect the propagation and absorption of light, causing the water to appear different colors. For example, if algae in the seawater grow in large quantities, it can turn the water a yellow-green color. Large amounts of silt or other minerals can also change the color of the water.

Finally, there is the depth of the sea. As the depth increases, long-wave light such as red is gradually absorbed, leaving only short-wavelength light able to penetrate deeper water layers, which makes the deep sea area appear more blue.

Of course, other factors, such as weather conditions, sky color, and the observer's visual perception, also influence our perception of seawater color. So, although seawater itself is colorless, it can appear to have a variety of colors depending on where and when we observe it. Of course, some lakes also appear to have different colors, and the same principle applies to the color of seawater!

Shuying felt dizzy after hearing this and said, "I don't understand! There are so many other rivers and streams, how can they be transparent? I still think that the sea water itself is colorful. Even though we are far away in the Far North Grassland, we have heard of these things!"

The Sixth Prince did not argue, but simply said to the Emperor Shenwu: "Father, I will invite you brothers to go hunting with me someday!"

Of course Emperor Shenwu readily agreed.

Little did they know that the Sixth Prince had secretly ordered people to build a river ditch several hundred meters long not far from the tent and inject a clear stream into it. He followed Lan Qingwu's advice, made some adjustments, and sent people to surround the new stream with thick curtains so that no one could see what was going on inside.

Two days later, the Sixth Prince invited his master and senior brothers to go and appreciate the Colorful Lake.

At that time, Mr. Yuan Zhiqing was accompanying the emperor in the middle tent, which was packed with people, including important civil and military officials, envoys from several countries, etc.

Xie Yiqian immediately perked up: "Master, let's go see the colorful stream! Can Junior Brother really make the river water turn colorful?"
