Contrary to the fiery colors just now, all the big mushrooms turned pale yellow at some point, like the yellow canopy on the emperor's head when he traveled.

Qiao Hua's heart was full of confusion. He had heard of plants whose leaves would turn in the direction of the sun, but it was the first time he had seen a plant that could change color. And the change from fiery red to golden yellow is too obvious.

The dwarf tyrannosaurus was immediately interested, and he observed curiously for a long time. During this time, the giant mushrooms changed from yellow to light green, and the color tends to gradually deepen.

Qiao Hua guessed that the color change of the large mushroom was likely to follow the order of the spectrum, and the basis of the change was the difference in the amount of heat absorbed. As for why this effect occurred, he only had a few conjectures, and he was not sure.

Qiao Hua originally wanted to observe for a while, but now he had no chance, because the waves on the sea reminded him that it was time for the high tide, and now he was still more than twenty miles away from the shore. It's not an easy ride, so he's going to try to catch a ride.

In the midst of the surging waves, Qiao Hua swam up and down. The tide tumbling forward and its own strong physique made this dwarf tyrannosaurus move forward extremely fast, and it had the style of a strong swimmer.

It's just that the sea breeze keeps pouring into his nose and mouth, which makes him really feel a little uncomfortable. After Qiao Hua roughly determined the direction, he simply buried his whole body in the seawater and moved forward quickly in a diving attitude.

The swimming fish that followed the rolling tide were left behind by this unlucky guest in the sea. In the end, a swordfish-like guy who rushed to the front was also caught up by Qiao Hua, who flicked his head and knocked the proud underwater formula car aside, because the unlucky fish was in his way.

But after sneaking underwater for about half an hour, Qiao Hua suddenly felt that there seemed to be some strange change in himself.

It's an amazing feeling. Qiao Hua felt as if he was drawing something from the water, and the cells on his skin seemed to have changed to another state in an instant, no longer closed to the outside, but becoming a channel for contact between the inside and outside of the body.

Although this change is not very obvious, the perception group of this dwarf tyrannosaurus body's body has already captured the information conveyed by the body at the first time. He could conclude that this was not caused by the interference of external factors.

Qiao Hua couldn't help but look down at the bottom of his body, and what he saw seemed to be no different from usual.

But the changes he could perceive became more and more intense over time. The lungs, which were originally in a tense state, gradually relaxed for some reason, as if they had lost their utility in this space.

A light flashed through the dwarf tyrannosaur's mind.

Are you breathing underwater on your skin?

Qiao Hua suddenly felt that his heart began to beat wildly. Obediently, this is my dream!

If it was in normal times, such an excited mood would inevitably make his oxygen consumption extremely fast, but at this time, all Qiao Hua could feel was a regular slight contraction of the body surface tissues. If it weren't for the sensitivity of my feelings, I wouldn't even be able to detect it at all.

And, after another period of time, the dwarf tyrannosaurus couldn't help but open its mouth and spit out some of the exhaust fumes that circulated through its body. If it was in normal times, he would never stop until he squeezed out the last trace of oxygen.

After a period of adaptation, Qiao Hua roughly guessed in his mind the principle of the breathing mechanism he was currently using based on his physical feelings.

If I guessed correctly, my skin is stimulated by strong water pressure, and the guidance of some aquatic animal genes in my body can filter out water molecules while allowing oxygen to pass through. Oxygen enters the tissue cells from various channels, and then enters the capillaries distributed throughout the body, and fuses with the blood to participate in the circulation of the whole body.

The dwarf tyrannosaurus had been tried many times, and now this skin respiration mechanism was not always open. The prerequisite is that it must be underwater, and it must be under a certain amount of pressure, whether it is external pressure or self-imposed pressure.

To explain it figuratively, we can compare these breathing channels on the skin to a kind of pressure valve, which will automatically open when the pressure is high enough and close automatically when the pressure is lost. Moreover, this kind of channel is unidirectional, and can only enter but not exit.

In this way, Qiao Hua quickly thought that the reason why he molted these days may be because he wanted to open this breathing channel after the skin was renewed.

And it was only at this time that the dwarf tyrannosaurus finally noticed a problem that he ignored today.

I plunged into the sea in the morning, and it wasn't until noon that I woke up and got out of the water, and the whole process took half a day. The longest record of apnea before this was only about an hour, and there has been no major breakthrough.

If I guessed correctly, I should have opened the gene lock for underwater breathing after the molting was completed, but after sleeping in the water for so long today, I still didn't notice this.

"I'm so stupid, I'm really ......"

At this time, only Xianglin's famous quotations could express Qiao Hua's speechless mood.

With the push of the tide and the frenzied intensity, it took only two hours for the dwarf tyrannosaurus to return to shore from its position on the island. Fortunately, the current only carried it vertically away from the shore, and after Qiao Hua swam to the surface, it didn't take much effort to find his base on the shore.

What made this dwarf tyrannosaurus rex strange was that a group of small figures appeared under the tree where the core was located.

When they got closer, Qiao Hua realized that it was a group of small dogs and bears. Bean paste was among them, playing with one of the big bears.

"Whew-"

There were also a few small canine bears who were obviously interested in the little squirrels in the trees, and kept raising their heads and roaring.

"Squeak-"

The pit lay on its stomach on the tree, apparently terrified of the small creatures with their sharp canine teeth below. However, as soon as he inadvertently looked up, the little squirrel suddenly caught a glimpse of a green figure with a turtle shell floating in the sea, and his eyes suddenly lit up, and he changed his previous depressed appearance and began to jump up and down between the branches.
