Ding Yang had never been to Huanglong Mansion before, nor had he seen Beihai Lake.

But along the way, I didn't listen to Xiao Da's introduction. Including the descriptions of the rest of the guards, it can be regarded as establishing an overall impression of Beihai Lake.

In particular, I also have a certain understanding of the environmental changes of Beihai Lake before and after the sunset catastrophe.

Originally, Beihai Lake was a saltwater lake, and not only did the lake live with many marine fish, but also many seabirds inhabited the surrounding area. When summer comes, there are always many birds hovering over the lake.

The fish caught in the lake are delicious, and some people often catch large fish that are 7o centimeters long.

There are many mushrooms growing around the lake, and it is said that it is also delicious. Ordinary people don't have any food at all, and they are all offered to the royal family as tribute.

It is said that there are many people who practice swimming in Beihai Lake, and the buoyancy is lower than normal, and learning to swim is always faster than elsewhere.

When Ding Yang pushed the horse into the lake, he immediately heard a terrible scream from the horse, and then trembled and rushed to the center of the lake like crazy.

In fact, Ding Yang didn't understand what was going on when he first heard the screams, and in his opinion, there was no accident for the horses to set foot in the lake.

Besides, when the horse first stepped into the lake, the depth of the lake had not yet reached the horse's calf.

However, after only a few steps forward, the horse's body began to decline quite a bit. Either the horse's hooves got stuck in the mud, or the lake began to deepen. It was clear that the water had overflowed the horse's thighs, and half of his body was in the water.

But the fact of the subsequent birth made Ding Yang dumbfounded, and the overall size of the horse seemed to shrink a little.

"I can't be dazzled, right? How could a creature shrink! "Ding Yang is a little strange.

Although the reduction is not large, it looks like it is only slightly smaller than just now. At first, Ding Yang thought that he was dazzled, but after a while, it became clear that he was not wrong.

Because the whole body proportion of the horse has shrunk again, so that there is a large gap compared to the beginning.

"This ...... No, I read that right, the size of the dark cloud is indeed smaller than it was at the beginning. Proportionally, it should have been reduced by two laps by now! Shrink...... How is this possible! ”

The facts are in front of you, but it's incredible. Ding Yang's eyes almost widened, and he was about to stare at the horse's body. But no matter what detail he analyzed, there was only one answer.

The horses did shrink in proportion, and they were still in two laps.

For example, at the beginning, the height of the horse can reach more than 16o cm. But now, after two laps, it is estimated that it will only be less than 15o centimeters.

Obviously, this is not because the horse's hooves have fallen into the silt at the bottom of the lake and caused the height to drop, but because the whole has shrunk.

"But what the hell is going on? What is the energy in the lake? It actually causes the whole creature to shrink in size proportionally! So where did the part of the volume that disappeared because of the shrinkage go? ”

The facts in front of him were incredible, which made Ding Yang immediately fall into deep thought and entangled.

Even Oni Dance once said that the basic rule of the universe is equal exchange. At the same time as the corresponding energy is released, the same amount of energy must be absorbed.

Only when the energy absorbed and lost are equal can the principle of conservation of energy in the universe be guaranteed. Otherwise, the universe will fall into an unstable state due to the asymmetry of energy. The unstable cosmic system can collapse anytime and anywhere.

The collapse of the universe can only lead to the destruction of the entire universe, so the principle of balance of energy cannot be shaken.

According to this logic, the overall shrinkage of the horse must be due to the transfer of energy, rather than disappearing out of thin air.

When a horse shrinks, it loses mass, so where does the energy that this part of mass converts go?

As Ding Yang cast his gaze on the cylindrical black hole in the center of the lake, sure enough, the horse shrunk again. If you look closely, you can see that extremely small energy fluctuations are surging towards the circular black hole in the middle of the lake by scattering and wandering.

"Sure enough...... The horse's shrinkage is due to the fact that its mass is converted into biological energy, which is absorbed by the mysterious core inside the central circular black hole. It's getting more and more interesting to absorb bio-energy in this way. ”

Just as Ding Yang was secretly calculating the time, the size of the horse began to shrink again and again. Every time it shrinks, it is the disappearance of the overall quality.

Through the keen six senses of the Xuanji Qi Lock, Ding Yang had slowly found traces of energy migration from careful observation.

This proves that there is nothing wrong with his initial hypothesis, that the mysterious core hidden inside the circular black hole in the center of the lake is devouring biological energy in a very special form.

Even in this process, the activity of the organism itself is guaranteed - the horses have not been damaged until now. At least outwardly, the horses themselves have not been harmed.

I don't see the horses bleed, and I don't see the horses sweating. Flesh, bones, and internal organs are still functioning normally. Ding Yang is even sure that all the organs in the horse's body are functioning normally.

But the only thing that is not normal is that the size of the horse is constantly shrinking in circles according to the proportions.

And every time it shrinks, there is a mournful sound from the horse. It seems that the horses themselves can sense that this situation is abnormal, but there is nothing they can do to prevent this change.

"If this continues, will the clouds themselves eventually disappear as they shrink?" With this question, Ding Yang endured the heartache and continued to observe.

His conjecture proved to be true, and the horses became smaller and smaller as the overall proportions continued to shrink.

In the end, it was completely submerged by the lake, but through the clean and clear water, Ding Yang could still see that the horse's form remained intact, and even the horse could breathe normally under the water.

This kind of common-sense subversion has a huge impact on Ding Yang.

6 mammals can breathe normally underwater, even if a small number of bubbles slowly pop up, which is unimaginable. If it weren't for the fact that the lungs were able to function the way the gills of a fish worked, it was the lake itself.

The lobes of the lungs are able to absorb oxygen from the lake water in this lake water.

What kind of sensation would it cause if we were to take this lake back to another time and space thousands of years from now?

Ding Yang almost didn't dare to imagine.

"Oh, what the hell am I thinking! This should not be the effect of the lake itself, but the mysterious core hidden in the black hole in the center of the lake. But is this mysterious core a Flame Sun Pearl? Alas, I really don't know much about Yanyang Zhu, and Ghost Dance didn't explain it to me carefully. ”

Although the logic is correct, Ding Yang still carefully scooped some lake water with a water prop and put it into a container. In the process, he was very careful to avoid the possibility of the lake water getting on his skin.

Seeing that these lakes are so weird, he doesn't want to get on them anyway.

After some water from the lake, the horses had completely disappeared during this time. Everything was gone, not a shadow remained. It's as if the horses that just entered the lake don't exist.

If it weren't for Ding Yang riding a horse from Linhuang Mansion in Shangjing all the way, the time they spent together was not short, and he almost thought that everything before was an illusion.

After all, the horse disappears out of thin air for no reason, and it gradually shrinks and eventually disappears, this process is too nonsense.

After careful observation, Ding Yang found that the props that were put into the lake were still there, but they sank into the silt at the bottom of the lake, and did not completely disappear like horses.

"What is the reason for this? Could it be that the lake also distinguishes between living beings and non-living objects? And only absorb living objects, ignoring life-costing objects! Could it be that there is some principle behind this? ”

Due to the scarcity of raw materials that can be used for experiments, Ding Yang has not yet been able to prove a certain guess in his mind.

It seems that the mysterious core hidden in the circular black hole in the lake is only aimed at the absorption of biological energy, and completely ignores other energy - Ding Yang just tried to throw in some iron and coal, and even dumped some diesel and gasoline into it.

But as he had guessed, all of them had just settled into the mud at the bottom of the lake, and had not disappeared.

Even diesel and gasoline were supposed to float on the surface, but they sank to the bottom of the lake.

"Mineral energy does not absorb, it only absorbs bioenergy. If you say that there is no problem in this, I won't believe it if I am killed. But what the problem is, it's not for me to guess. ”

As the sun continued to set, the sky became darker and darker.

Ding Yang didn't know if it was an illusion, he felt that the temperature around him seemed to be gradually decreasing.

When the sun went down, it was obvious that the air around me was not as hot as during the day. Even the temperature of the lake seemed to be decreasing, but Ding Yang didn't dare to test it with his hands.

But thinking about what Ghost Dance said before, this guess should be correct. As the time gets later and later, the power of the Flame Sun Bead is gradually decreasing.

"From this point of view, the mysterious core inside that round black hole is really becoming more and more like a Flame Sun Pearl! But even if I pick up the Heart Bell and summon Yuan Qingdao Elder to come over, I still can't take it away! If you don't go into the circular black hole, it seems that there is no way to get the Yanyang Pearl! So what do I do to dive through the lake and into the circular black hole without any damage? Hmmm......"
