Time Master of the City

This sleep, two people sleep for a long time.

Long term mental high tension brings a very strong sense of fatigue, although they are now very strong, physical quality has been greatly improved, but still need to rest in order to better recover.

However, there is no sense of time here. Once you wake up naturally, it feels like a night.

Wu Hao still got up earlier than Ling Fei Er and didn't disturb her. He got up and baked a piece of fish and made a pot of fish soup.

"Get up, girl."

Ready, the little girl picked up from the ground.

"Good morning, brother Linghao."

Ling Fei Er stretched lazily in his arms, hugged him tightly and didn't want to get up. Every time when she woke up, the little girl was a real lady.

"Drink some water first and get up to eat." Wu Hao put her on the ground.

"Oh."

Ling Fei Er yawned a lot. As a result, he gargled the stone cup in his hand and drank the rest of the water.

"What are we going to do today?" Ling Fei Er asked while eating, just wake up, obviously not in the state.

"Continue to explore and try to find a third cave as soon as possible. The next thing we need to do is keep going, all the way forward. " Wu Hao said.

"OK, we'll start work after the rest." Ling fei'er laughs, without complaining. Wu Hao smiles and touches her head.

After a short rest, they took off their clothes and jumped into the water.

Now there is no need for one person to carry the crystal stones. Two people can work together. The efficiency is double. One crystal stone is inserted every five meters, and one crystal stone is inserted every five meters. All the way forward, more than 13000 meters are advanced at the end of the day. With their current physical fitness, it is not a problem to stay in the water for a few more days, so before they are hungry, They didn't plan to rest. They kept inserting crystal stones into the stone wall all the way. When they reached 17000 meters, a blue light in the distance attracted their attention. They looked at each other and swam towards the blue light immediately.

It's a new cave.

Just below the blue light, they were excited.

The opening is very small, less than 10 square meters. It is estimated that it is also a very small cave, but it doesn't matter to them. What they need is not necessarily a big cave, as long as it can accommodate them to rest and breathe.

They jumped up and flew into the cave.

As Wu Hao expected, the cave is very small, estimated to be only a hundred square meters, and its height is also very low. If it flies too high, it will accidentally hit the top of the stone wall.

But it doesn't matter, as long as it's a cave and can accommodate them for a rest, it's enough.

"Come on, let's go back."

At the corner of his mouth, Wu Hao pulls Ling fei'er to jump into the water again and follow the direction of the crystal stone to return to the second cave.

Now that there is a new cave, the power of this cave must not be wasted. Two people begin to absorb the power of this huge cave. The blue light of the cave gradually becomes dark blue, and the dark blue gradually becomes darker until it disappears.

Back in the water again, they took back the crystal stone on the stone wall all the way. Two people came to the newly discovered cave and threw the fish in the space ring back into the cave for refrigeration. They cooked a pot of fish soup and warmed their bodies. Without doing more rest, they jumped directly into the water and continued to search for a new cave.

Their internal strength is more and more abundant, and their physical functions are more and more powerful. Whether it is the ability to fight hunger or cold, or the duration of power output is greatly increased. The most direct manifestation is that they are working more and more efficiently in the water.

After going into the water for more than 30000 meters, we finally found the fourth cave.

But this cave is very different from the first three caves they found. What they saw from a distance was not blue light, but a red light.

The red light is far away from them, but the light is very strong, and the water temperature rises obviously within the sight.

Is this a cave of hot rock?

With doubt, Wu Hao pulls Ling fei'er to the bottom of the cave.

Hot!

Even if they haven't gone up, Wu Hao can be sure that this cave is absolutely a huge cave composed of hot rocks. They haven't gone up yet. They feel that the water under the cave is about to boil. Fortunately, their physical fitness is strong enough, otherwise they can't stay in such a water temperature.

This hole is about the size of a football field. How big is the space inside?

Wu Hao calms down and pulls Ling fei'er into the cave.

Great heat!

It was like entering a huge oven. At the moment of entering, the water vapor on the two people was evaporated, and they were smoking.

The pool in the middle of the cave kept emitting white smoke, but the cave was too hot for water vapor to gather, and the cave was wet and stuffy.

"This cave is so big." Ling Fei Er looks around the cave in front of him, surprised.

"It's really big enough." This cave has 100000 square meters at least, right?

"But it's too hot to stay here."

"But the energy here must not be wasted. If we absorb all the energy here, hehe." Wu Hao laughed and said nothing. He flew directly to the top of the cave and began to absorb the energy of the hot rock in the cave.

"Hee hee." Ling Fei son is also not polite, hee hee a smile, casually found a place to begin to absorb.

Although icestone and pyrolith release two different temperatures, their structures are similar. With the decrease of energy, the heat released will also decrease, which will lead to the decrease of temperature. Wu Hao and lingfeier absorb the pyrolith energy in the cave quickly, and the temperature of the cave gradually begins to decline, which is very slow at the beginning, However, as their absorption speed gets faster and faster, they absorb more and more energy, and the faster the temperature drops behind. When the orange red light in the cave gradually turns into dark red light, the temperature in the cave is estimated to be only more than 20 degrees, reaching an optimal temperature range for rest.

Wu Hao didn't know how long it took to absorb these forces, but he was very satisfied with the power accumulated in his body.

Take Ling fei'er back to the previous cave, roast a piece of fish, cook a pot of fish soup, eat and drink enough, have a little rest, collect the rest of the fish, absorb all the energy of the cave, while collecting the crystal, and return to the hot rock cave.

The oxygen in this cave is insufficient, so it is not suitable to stay for a long time. Wu Hao doesn't plan to stay here for a long time. He just wants to take it as a temporary foothold. They don't have a rest, so they just start to explore the next cave.
