The average temperature outside Repulse Bay fluctuates between 20 degrees Celsius, which is not a large range, but below 1,500 meters underground, the temperature has risen by at least 10 degrees Celsius, reaching more than 30 degrees, and this temperature has hardly changed. Pen, fun, pavilion www. biquge。 info

The rocks on both sides of the cave are red, and they should be limestone, but Qiubai is not sure.

After taking a few steps forward, a huge space suddenly opened up in front of Qiubai, Qiubai turned off the flashlight, and some light could be faintly seen, and it was not extremely dark here.

This underground space is a large pool, which is dug by steel claws and iron claws for half a month, the area is quite wide, and it takes more than half an hour to walk along the edge, and the scope is still expanding.

The sound of gurgling water sounded, Qiubai looked to the left, a pool of spring water flowed out of the big hole of the football, poured into this pool, this spring is actually a hot spring, the water temperature is about 30 degrees, but compared with the temperature of this underground, it is nothing, like this spring, nine places have been dug in this underground pool, and the underground water resources are quite abundant.

The underground pool is relatively flat, three meters high, the water depth is about two meters, and there is a stone path on the side for Qiubai to walk, and the stone path is also quite wide, because pangolins also need to pass through this stone road.

Qiubai walked along the stone road, because of the underground environment, so this stone road is crooked, Qiubai also wants to dig them into a straight road, but it is not realistic, because behind the stone wall of the stone road, many of them have traces of groundwater, if they are all dug up, the water flow will be too big, with the simple drainage system of the current pool, the water can not be discharged at all, and this underground space will be flooded, and Qiubai will have no way at all.

Qiubai shone a flashlight in the pool, a huge stone pillar towered in the dang, this stone pillar is a bit like corn that has been gnawed on both sides, about twenty meters thick, it is a whole piece of rock, Qiubai did not let the steel claws dig it up, but let it stand here, as a support, although Qiubai knows that if this space is really going to collapse, this seemingly thick pillar is actually useless, but psychologically it is more comfortable, looking at the pillar to be more reassuring, Otherwise, there is nothing in the space and space, and it always feels empty.

There are more than a dozen stone pillars like this in Qiubai, and there will be a big pillar almost every 100 meters.

Walked a little further, you can see the light in front, a ray of light from the top vertically down, this is the sun's rays, the steel claw dug a hole from there, the sunlight is drawn down, this hole is also quite hidden in the ground, Qiubai is specially looking for a piece of thorn bamboo, this thorn bamboo is a shrub, there are spikes on the leaves and stems, almost no one dares to go into the thorn bamboo bush to get Se, Qiubai used Tai Sui water to water this thorn bamboo bush a little, so that they develop bigger and bigger.

In this light was a platform, to which a stone path was attached, and on the platform was a stone-walled flowerbed in which the golden tree was now planted.

Because it can communicate with the golden tree, Qiubai knows that there is no problem with the golden tree now, and it is very important for plants to survive sunlight, and the golden tree is no exception, but because one person and one tree can communicate with each other, so how much sunlight the golden tree needs Qiubai can also know, and now this sunlight is just right, and it will not make the golden tree stunted.

"Coming?" The Golden Tree said softly, although he was already quite familiar with Qiu Bai, the Golden Tree still had that timid tone.

"Well, I also brought the water hyacinth, this is a mutated water hyacinth, where is it planted?"

"Just put it out on the water."

The vitality of the water hyacinth is quite tenacious, as long as the water temperature is above ten degrees, almost any sewage can grow quickly, the water in this pool in Qiubai is a mixture of hot spring water and ordinary water, the temperature is about 312 degrees, the water hyacinth must grow fast.

"Just throw it in there?"

"Well, yes."

Of course, Qiubai could only choose to believe it, squatting down and throwing the mutant water hyacinth into the water to watch it float in it.

"Well, it's okay to stay here, right?" After the matter is done, of course Qiubai has to care about the golden tree.

The reason why the golden tree is placed here, of course, is that it needs to use its special ability to cultivate mutant water hyacinth, and the second is because the underground space is getting bigger and bigger, and the scope of the divine thoughts of the tea tree and the poplar tree can no longer cover the entire space, the golden tree is planted here, if something happens underground, the golden tree can use its divine sense to notify the tea tree, and the tea tree is notifying Qiubai, and the next thing for Qiubai is to transplant the poplar tree to this ground, of course, this first depends on whether they are willing or not, but Qiubai asked their opinion, It's all quite willing, there's no difference between underground and above.

Now the poplar's situation is a little difficult, the rapid growth of weeds in the plundering of its living space, its growth degree is a big difference compared with weeds, if you don't often inform Qiubai to shovel out the weeds around it, poplars can't absorb the sun, if the poplar goes underground, you don't have to worry about the sun.

"Well, it's good to stay here." The golden tree replied, the plants are easy to satisfy, at least the three plants that Qiubai encountered, they usually have little requirements, Qiubai is kind to them, they feel very content, compared to some human greed, they are like angels.

"Oh, if you're not satisfied, then say, okay, I'll take a look around."

"Well, go ahead."

Along the stone road, Qiubai turned half a circle, came to an arch bridge, there is a big crack under the arch bridge, this crack is the main outlet of the pool now, is a large hole about six meters wide and about one and a half meters high, this outlet is not dug by steel claws and iron claws, but at the beginning, Qiubai just let the steel claws slightly add a little work, Qiubai himself did not enter this crack, but let the steel claws enter, this crack eventually leads to where the steel claws did not poke out, but it must be quite deep.

Nine springs are poured into the pool from all sides of the pool, and then flow out from this large fissure and several small fissures, keeping the water depth at about two meters, which is the main structure of this pond now, and in the next step, Qiubai will let the steel claw and iron claw dig a few more pools, and then connect these pools in series, and finally form a huge breeding pond.

"Golden Tree, what about the fish I put away? Still alive? Qiubai asked suddenly.

Qiubai put four fish in this pond, carp, grass carp, crucian carp, and cinnamon fish each put one, the purpose of course is to experiment whether they can live under this, or whether they grow well, and then improve the underground environment according to their length of life or the cause of death, Orange Orange sometimes comes down to record the condition of the four fish, such as whether they are sick, whether they are unwell, or simply die.

"They're near me, and now they're all swimming under the water hyacinth." Golden Tree replied quickly.

Not only do plants need sunlight, but animals also need sunlight, so these four fish instinctively swim to sunny places, and now that there is sunlight near the golden tree in the underground, it is not surprising that they will gather there.

"And it doesn't seem like there's any major problem with them, the scales haven't fallen off, but they don't seem to have grown meat."

Qiubai also discussed with Orange Orange Ningning at that time, saying how much should be stocked in this underground pool, Orange Orange said that there are at least 100 of the four kinds of fish, and Qiubai only put one, because it is difficult to observe if there are more, and until now, Qiubai has not fed these four fish, which is naturally to test whether there is plankton in the groundwater, and now it seems that there should be, otherwise if you don't eat for five days, the four fish should have died a long time ago.

In fact, if he could catch the fine-scaled fish, Qiubai wanted to raise them below, but Qiubai didn't dare to go to the cave of the ten teams.

"Just eat plankton, five days without growing meat is normal, and now it is still alive, proving that it is entirely possible to raise fish in the ground, and when you really raise fish, get some aquatic plants in the pond as food for fish, the water temperature in the pool is right, and the aquatic plants will grow quite quickly, so you don't have to be afraid at all." Qiubai said to himself.

"Still, sunlight is still a big problem, there is sunlight in the pond just like the golden tree, and the fish are pouring in, and now there are only four, and if thousands have to crowd it into a dense crowd, do you have to let the steel claws dig a few more holes?"

It's not troublesome to dig a hole, don't look at the pool now more than a thousand meters from the ground, but if the steel claw really wants to dig, it's only a matter of a few minutes, the trouble is the ground, Qiubai can't blatantly repair the hole in the ground now, digging too big is easy for people to fall down, and the sun can't shine in if it's small, it's useless.

"Or light it with a light bulb?" Qiubai thought of another way.

Science has proven that using a high-power bulb to power up can replace sunlight to a certain extent, pay attention, just replace it to a certain extent, real sunlight is irreplaceable, but Qiubai thinks that a fish only needs two to three months to grow up, as long as there is no problem in these two to three months, the fish can be sold, since it is sold, then there is naturally no problem.

On the edge of the pool, there is a hot spring, the diameter of the spring is about 20 centimeters, it is a quite large hot spring, the water temperature is 42 degrees, it flows down from the stone wall, passes through a small pit of three meters, and then flows into the pool, Qiubai arrives at the edge of the hot spring, takes off his clothes, and sits in.

This pit is naturally a place where Qiubai usually rests, the hot spring water flows through the small pit, washing Qiubai's body, bringing a comfortable enjoyment, here can usually accommodate two to three people to take a bath together, Wang Cheng sometimes comes over with Qiubai, usually if you want to hide people's eyes, Qiubai will take a bath in the rainbow spring, if it is night, it will rest here, and the steel claw and iron claw are naturally working.

As soon as he lay down in the hot spring, Qiubai didn't want to move, his whole body became lazy, and he wanted to sleep in a daze.

"Qiubai, Qiubai, wake up, what do you see I found?" The Golden Tree suddenly said in surprise, and Qiubai asked lazily, "What did you find?" ”

"Hey, a fish, I don't know where it came from."

"Oh!?" Qiubai was suddenly a little excited, there would actually be fish? "Where?"

"Come here, it's on my side."

Qiubai hurriedly climbed out of the hot spring, shook his body, and dried the water on his body a little, then put on his clothes and ran over, "Where?" ”

"On your left, in the water about twenty meters ahead, do you see it?"

Qiubai's eyes widened, and finally he took a flashlight at it, okay, he really saw it, but it was just a black shadow, what the fish looked like Qiubai couldn't see clearly at all, but he could see that the fish was a foot long.

"Can't see wow... What to do? ”

"Go down and catch it." Golden Tree said.

"Uh, you really think I'm a black eyebrow, I don't have that ability to catch fish in this kind of water." Qiubai was speechless. (To be continued.) )
