In this subterranean ocean, it seems that some kind of ecological balance has been formed. As a result, the dinoflagellates in this underground fluorescent ocean, although they bloom in large numbers, do not destroy the water column. Make it impossible for other creatures to survive.

This fluorescent sea water, the waves set off layer upon layer, spread from the front of the eyes to the sky, spread to the sides of the side, immeasurable vastness. The light fluorescence can make the sea water not deep along the coast clear and visible. In this sea water, there are some primitive fish and primitive sea creatures that Yun Lei does not know, swimming around, frolicking and chasing.

The churning seawater, in the crystal clear, swells and breaks. Like an indescribably large gem.

Rao Ya was drunk when she saw it. Even Yun Lei, walking here, couldn't help but let out a sigh.

Rao Ya said to Yun Lei: "Even if my flesh and blood are eroded and dissolved by the Yin Spiritual Qi, I really can't be saved, I can see such a scene before my flesh and blood disappear, I am also satisfied." ”

Yun Lei said to Rao Ya: "People go to high places, and water flows to low places. In this piece of heaven and earth, the lowest place should be in this sea. And the eruption of the underground magma is the closest to the earth's crust!"

"It's the lowest part of this underground space. It is also the place where the spiritual fire of heaven and earth is nurtured. and the place where the spiritual fire of heaven and earth is most likely to appear!"

"According to the records of the members of the Prussian expedition, the quiet magma river came and went, full of spiritual fire. ”

"Although it can be regarded as the spiritual fire of heaven and earth, it should not be the body of the spiritual fire of heaven and earth. It can only be regarded as a doppelganger, a projection, or a tentacle of the spiritual fire of heaven and earth. According to my speculation, the body of the Heavenly Earth Spiritual Fire should be somewhere in this underground space, in the lowest underground ocean!"

"Your body can last at least ten days. In the past ten days, the probability of finding the Heavenly Earth Spiritual Fire and suppressing and refining it is not low. You take a rest first, I'll go find you some fresh ingredients, something to eat, and then we'll cross the sea and find the spiritual fire of heaven and earth!"

Rao Ya hugged Yun Lei, rubbed in Yun Lei's arms, and sniffed Yun Lei's breath. I feel that there are Yun Lei's words. Even if it becomes a ghost and accompanies Yunlei, it is worth it.

In Yunlei's space gourd, there is a lot to eat. However, in such an environment, it seems too inappropriate to eat cooked food and bento boxes that are tired of eating in the outside world. It's better to eat some specialties from the underground space.

In this underground space, Yun Lei knows at least two kinds of mushrooms, although they can emit fluorescence, but they can be eaten, one is the honey ring mushroom. This edible fungus is generally medium-large, with a cap diameter of about four to fourteen centimeters, pale earthy yellow, honey-colored to light yellowish-brown, and sepia-brown after aging, with small flat or erect scales in the middle, sometimes nearly smooth, with striped edges.

The mushroom flesh is white. The folds are white or slightly fleshy pink, and dark brown spots often appear in old age. The stipe is elongated, cylindrical, slightly curved, the same color as the cap, fibrous, the inside is soft and hollow, and the base is slightly expanded. The rings are white, the upper part of the stalk, often double-layered, fluffy, and creamy in the later stages.

The part where it glows is the mycelium. On the surface of the earth, on summer nights, it also emits fluorescence.

In this underground space, those honey ring fungi, although fluorescent and brighter, are larger, and the diameter of the cap is about 20 centimeters. However, the characteristics of its main body remain the same. There is no problem with consumption.

Another type of edible mushroom that glows is the small mushroom with clusters. It's just that this mushroom is too small and not very numerous, so it was abandoned by Yunlei.

However, not far from the fluorescent coast, there were a large number of bracken growing like a lawn, which surprised Yunlei very much. This stuff tastes good. It is completely non-toxic. Because, its underground rhizomes, rich in starch. In the memory of the famine among the Chinese people, this thing was also used as life-saving food.

In addition, there are many ferns in this underground space, not only bracken, but also water fern and purple fern. Yun Lei easily made a pot of bracken mushroom soup. In addition, he found an alcohol stove from the space, lit it, caught an ancient fish from the sea, whose name was unknown, and began to grill the fish.

This kind of fish has long been extinct in the outside world, at least Yun Lei has never seen it. However, in the shallow waters of this underground ocean, there are many of them! Fat and large, a small fish can weigh at least seven or eight pounds! It is a pity not to eat two.

Yun Lei's craftsmanship is also good, but after a while, this huge fish has already come out of its aroma, and the flesh has turned a beautiful white. And the aroma of this grilled fish escaped, and I don't know what alarmed.

Yun Lei and Rao Ya, when they were eating this huge grilled fish, but they heard not far away, and in the darkness beyond their eyesight, there was something, and they thought about it. It seems to be the footsteps of some kind of animal walking, or the sound of some kind of flying animal flapping its wings.

In fact, Yun Lei and Rao Ya, when they were heading towards this fluorescent sea just now, sensed that there were not only glowing mushrooms, some silent ferns, and ancient insects in this underground space.

There are also creatures that lurk in the dark, but are quick to see the opportunity and are reluctant to show their heads. Both in the air and on the ground. These creatures are not ancient insects, but they are mixed in with ancient insects, hiding their shapes, leaving Yunlei and Rao Ya nowhere to be found.

And Yun Lei and Rao Ya have no interest in exploring specifically.

Although this underground world, this legendary Shambala, does have a completely different ecosystem from the outside world, and there are many creatures that have survived since ancient times. It is of great scientific value.

As long as Yun Lei and Rao Yaduo stay for a few days, investigate a little, and collect some specimens to take them to the outside world, they can shock the whole world. Let many traditional biological theories completely collapse.

However, Yun Lei and Rao Ya do not have this interest and time. Their main purpose is to find the spiritual fire of heaven and earth.

Therefore, even if Yun Lei and Rao Ya sensed the darkness beyond their eyes, and some unknown creatures secretly followed the action, they didn't care. With the cultivation of the two of them, apart from the existence of the Yuan Infant Stage, there are no living beings that can pose a real threat to them.

After Yun Lei and Rao Ya finished eating the grilled fish by themselves, Yun Lei took out the small boat that had just taken them with them and followed the flow of the underground river after many impacts from the space gourd. After Rao Ya boarded the boat, he looked for one direction and sailed away.

With Yun Lei's current cultivation, he rows without oars at all. Of course, it's not by the waves. As long as the cloud thunder is urged by spiritual power, the boat under his feet will shoot straight out like an arrow from the string.
