After swimming on the lake, Ao Muyang slowly dived down with Lu Zhizi.

Soon, Lu Zhizi's brows frowned.

Ao Muyang knew what was going on. When diving, the water pressure increased, and the inside and outside of the ears could not maintain balance. The gradually increasing air pressure would slowly push the eardrum into the ears, causing discomfort.

If it is forced to descend, it may cause serious consequences such as bursting of the eardrum. There is a ethnic group in Southeast Asia called the Bayao people. They float on the sea all their lives. In order to overcome this problem, everyone will pierce the eardrums when they are born!

Ao Muyang observed Lu Zhizi's expression, and after seeing her frown together, he brought her to the surface again and said, "Discomfortable ears? I will teach you two methods. The first one is called Vanshi's technique. You pinch your nose and try to blow out your breath slowly..."

Lu Zhizi took a dozen breaths, nodded and smiled, "It's much better."

Ao Muyang also nodded: "Okay, let's teach you the technique of Toebi. You plug your nostrils with your fingers and then swallow them. This way you can open the throat tube and move your tongue to send air into the trachea to maintain the balance of internal and external pressure. When you feel uncomfortable when you dive, use these two methods to adjust the pressure of the ear canal and respiratory tract."

Lu Zhizi looked at him admiringly and said, "You can go to be a diving coach, how can you know so much?"

Ao Muyang shook his head lightly: "Is this a lot?"

This is really not a lot. He has spent a lot of things on Baidu in the past two days, but he has not had the ability to remember it all. He remembers these things now...

Lu Zhizi gave her admiring eyes at the right time: "Of course, you know a lot."

Ao Muyang raised his head and said, "It's not that I'm humble. These are really basic methods. Did your diving coach kill pigs in the past? You don't understand this."

Lu Zhizi said, "I don't have a diving coach."

Ao Muyang wondered: "Didn't you say you've learned diving in Miami?"

Lu Zhizi: "Let's learn by yourself."

Ao Muyang gave a thumbs up, domineering! Niu Pen! You are amazing! Three-combo!

After diving again this time, everything went much smoother.

After many ups and downs, Lu Zhizi learned very quickly. With the help of a submersible, she could soon penetrate more than ten or twenty meters under the water.

At this depth, the sun is still bright, and the summer sun is very strong and can easily penetrate forty or fifty meters. Of course, you cannot expect the brightness of the underwater to be the same as on land.

The water plants at the bottom of the lake swayed, and some freshwater fish came in and out. When you lifted the water plants, you could see the snow-white sand. There were stones of large and small scattered in some places. Lu Zhizi found some water snails on a stone and immediately became happy.

Ao Muyang floated to the water to breathe after a while, and he couldn't let Lu Zhizi notice the abnormality.

In this way, Lu Zhizi kept looking for water snails for him and asked him to take him on the boat.

There are fish and shrimps in the lake, but they cannot be caught by hand, so the water snails and river clams became the targets of Deer Zhizi.

After collecting some water snails and river clams, Lu Zhizi was less interested and her interest in diving was no longer so high.

Ao Muyang smiled, went over and grabbed her hand and took her to swim for a while before continuing to dive.

Further down, the water became deeper and the light was worse. Lu Zhizi wanted to turn on the headlight, but Ao Muyang stopped her and shook her head to her to signal her not to do so.

After he changed his breath several times, a trance pillar appeared in front of them.

At this time, Ao Muyang swam above Lu Zhizi and helped her turn on the headlight. In an instant, the halogen light shot out a wide yellow giant sword. The giant sword passed by was full of giant trees!

Yes, trees appeared at the bottom of the lake, and this tranced pillar was actually a forest...

I saw tall and short trees rooted at the bottom of the lake. Their bark was dark-brown and the branches were short and sparse, but there was a green area on it. There was also green in some places in the trunk, as if they were growing underwater.

Some carp and crucian carp shuttled through it, and the figures of silver carp and white carp could be seen from time to time. Ao Muyang sank into the water and stirred the bottom of the lake. Suddenly, a big catfish emerged...

Lu Zhizi was full of surprise. She had a wide range of knowledge and knew that some trees could survive in the water, such as metasequoia and red willow.

But these trees are just roots in the water, unlike this forest. They are all underwater as a whole, and they are in such a deep lake. This is simply a miracle!

Ao Muyang asked her to watch the woods by herself. He floated up and changed his breathing, but he did not really surface. There would be light guidance, so he could monitor Lu Zhizi's vision.

The headlight is fixed on Lu Zhizi's forehead. If she wants to turn her head or raise her head, the light will change its angle and position.

Looking down from above, Ao Muyang saw a school of noodles fish. The bodies of these fish are as slender and narrow as chopsticks, almost transparent throughout. They are a great freshwater fish.

In addition, noodle fish also has seawater fish species, but its taste and nutritional content are not as good as freshwater fish.

Ao Muyang was very sorry that he did not bring a fishing net, otherwise he could catch it and make dinner by one net.

Lu Zhizi also noticed the noodle fish and fish. She slowly reached out to her. The fish thought she was also a tree at the bottom of the lake. She was not afraid, but slowly passed by her.

This scene is very beautiful, and Ao Muyang regrets again. He just needs to have an underwater camera. It must be great to take such a photo.

Lu Zhizi looked at the little fish passing by her and was filled with joy, but suddenly, the little fish became panicked and disappeared in a hurry.

She was wondering, a black shadow fell from above her head, hugged her from behind and moved her several meters in the water, and a hand groped on her waist.

Lu Zhizi was shocked, and she quickly turned her head and saw that it was Ao Muyang holding her behind.

This made her feel sank. What is he going to do?

Ao Muyang hugged her and moved her hand and stretched out his hand on her waist. Then he pushed her away and raised his arms. The yellow light shone on it, making the quick knife in his hand shine coldly!

In addition to the lights, it also shone a fish. Lu Zhizi looked closely and saw that the fish was very big, about one and a half meters long, and it looked like a torpedo and had a cylindrical shape.

Its body is pointed, head is pointed, and mouth is pointed and long. Compared with its scales, its fins are small, and its overall silvery white, with only a gray-brown color on its back.

Lu Zhizi saw this big fish with her own eyes for the first time, which could grow such a big fish in fresh water!

The big fish was very fast and had a very arrogant attitude. After it appeared, it was shuttled quickly, not afraid that Ao Muyang and Lu Zhizi would actually swim around them.

The distance was very close, Lu Zhizi saw the sharp and sharp teeth in the fish's open mouth, like shark's teeth!

Taking advantage of the moment when the big fish swam past, Ao Muyang waved his arm suddenly, and a diving knife cut across the big fish's body.

Suddenly, the fish blood flowed out!

The big fish is not as cruel as a shark. After being injured, it swings its tail and disappears quickly.
