Below is the knee-high water of the underground river, and above it is covered with thick thunderclouds.
This is the first time Qin Sang has seen such a strange terrain.
How can the power of thunder be given birth to in the dark underground?
Qin Sang couldn't figure it out.
Those six-petaled pansy plants grew at the other end of the underground river, taking root between the cracks in the rocks. In addition to that place, Qin Sang also found two traces of excavations in other places on the bank of the underground river.
From the traces, Qin Sang guessed that it might not be a magic medicine, but some kind of ore.
Not only does the six-petaled pansy grow here, but it also has exotic minerals, making it a treasure.
The ore fell into the hands of a strong man from the Wu tribe and was mined very cleanly. As for what kind of ore it was and how much it was worth, there was no way to verify it.
The immature six-petaled pansy will wither immediately after being forcibly picked, and there will be little medicinal power left.
Judging from this man's behavior, if the six-petaled pansy had not had this characteristic, he would have dug up all these plants before they matured.
Perhaps, the formation of thunderclouds is related to that unknown ore.
Qin Sang stood in the water, looked up at the thunder clouds, and then looked down at the Tianmu Butterfly in the palm of his hand.
After entering the underground space, the Sky-Eye Butterfly woke up on its own, and then came the thought of longing. It couldn't wait to come out. The target was actually something in the thunder clouds.
If there is a treasure in the thunder cloud, it must have been taken away by a strong man from the Wu clan, right?
As a monk of the Witch Clan, if nothing unexpected happens, he also has the Insect Gu.
Are thunder clouds only attractive to Tianmu butterflies?
Qin Sang did not let go of the Tianmu Butterfly rashly, but caught the fat silkworm. He found that the fat silkworm was indifferent to this, which confirmed his guess.
The power of thunder in the thunder cloud is not as terrifying as the world outside. The lightning produced is very thin, but it is also wishful thinking to probe into it with spiritual consciousness.
Qin Sang meditated for a moment, stirring up his true energy and shaking the thunder clouds.
For a moment, the cave was filled with smoke and clouds, and there were bursts of thunder. Qin Sang soon stopped because he had already seen the core of the thunder cloud. There was nothing else inside, just a cloud of gas.
The search was fruitless, so Qin Sang had no choice but to let go of the Tianmu Butterfly.
But I saw the sky-eyed butterfly flapping its wings happily, flying below the thundercloud, and began to hover there.
After a while, the Celestial Eye Butterfly hovered in the center below the thundercloud, and then began to flap its wings rapidly. The Celestial Eye Butterfly was not weak anymore, and it flapped its wings to create strong winds, stirring the thunderclouds.
But unlike Qin Sang, the strong wind generated by the Sky Eye Butterfly has a strange suction force. While the thunderclouds shook, a wisp of milky white smoke gradually formed in Qin Sang's field of vision.
This wisp of smoke is extremely thin and is pulled into a line under the action of suction. The other end is actually the mouthparts of the Sky Eye Butterfly.
The Tianmu butterfly is absorbing this wisp of smoke!
Qin Sang had a look of surprise on his face. In his opinion, thunderclouds were very ordinary. They were simply condensed water vapor, but they were regarded as delicacies by the Heavenly Eye Butterflies. Qin Sang could clearly sense the joy and contentment of the Heavenly Eye Butterflies.
"There will be something in the thunder clouds..."
Qin Sang fell into deep thought, glanced at the six-petaled pansy in the distance, and ducked past.
The six-petaled pansy is very beautiful and colorful, and there are actually six of them, which is enough for the Celestial Eye Butterfly to grow to the peak of its second transformation.
In the ancient books of the Yuling Sect, the introduction to the six-petaled pansy is very simple. It only says that it is a kind of spiritual flower that the heaven-eye butterfly likes to eat and can be used to cultivate heaven-eye butterflies.
There is not much description of the characteristics of the six-petaled Corydalis and its growth environment.
"Because of the unknown white mist in the thunder clouds, spiritual flowers like the six-petaled pansy are born. And what the Sky Eye Butterfly really likes is the white mist?"
Qin Sang could only make random guesses.
He took out six jade boxes and carefully picked away the six-petaled butterfly. He looked around and saw that there were no other treasures, so he returned to the center of the underground river and paid attention to the movements of the Tianmu Butterfly.
In a short period of time, the white mist became thicker and thicker, becoming as thick as chopsticks.
The small body of Tianmu Butterfly is like a bottomless pit, swallowing up the white mist in its big mouth, not knowing how to be satisfied.
At this moment, dense thunder suddenly sounded deep in the thundercloud, and then, there was a sudden flash of lightning in the middle of the white mist, and the two merged into one.
Seeing this scene, Qin Sang's expression changed, and he was about to order the Heavenly Eye Butterfly to avoid it. Unexpectedly, the Heavenly Eye Butterfly showed no fear. Instead, it fluttered its wings and flew up, sucking in the white mist and lightning into its belly!
Qin Sang was stunned. He had not expected this situation at all and had no time to stop it. He hurriedly flew over and watched the changes in Tianmu Butterfly nervously.
What are the consequences of swallowing thunder?
Even the tiniest thunder represents the most violent force in the world!
The Sky Eye Butterfly hovered in mid-air, the white mist also stopped, the weather was calm, and it seemed to have fallen into a deep sleep.
Qin Sang was very nervous and communicated with Tianmudie's consciousness. The good news was that Tianmudie's consciousness was still stable, but its breath was not so stable.
The Tianmu Butterfly lay on Qin Sang's hand, wisps of white mist shrouded it, and its body was trembling, obviously affected by the thunder.
Qin Sang was caught off guard by Tianmu Die's act of his own initiative, but he certainly couldn't sit idly by. The only thing he could do was to use the connection between their bloodlines to instill true energy into it to help it.
As time went by, the shaking on the Tianmu Butterfly began to gradually weaken, and it had passed the most difficult time. Then, its breath finally returned to stability.
Qin Sang secretly breathed a sigh of relief, and went over to take a closer look, only to find that the Heaven-Eyed Butterfly had not changed much after swallowing the power of thunder. Only the patterns on its wings seemed to be a bit more dazzling.
Unexpectedly, the Sky Eye Butterfly flapped its wings again and flew up again, continuing to swallow the white mist and thunder.
Qin Sang's eyes flickered, but this time he didn't stop him and allowed Tianmu Die to do what he did.
Every time it rises and falls, the Sky Eye Butterfly becomes more and more relaxed, swallowing the white mist and thunder in its mouth.
Until the last ray of white mist was swallowed into its belly, the Sky Eye Butterfly returned to Qin Sang's palm and lay there, looking a little listless. At this time, its wings suddenly began to glow.
There is silver light swimming among the strange patterns.
The light became brighter and brighter, filled with white mist, and finally turned into something like a thunder cocoon, wrapping the Heavenly Eye Butterfly. The Heavenly Eye Butterfly lay in the thunder cocoon and fell into a deep sleep.
Qin Sang watched the entire change process without intervening, but he had been nervously paying attention to Tianmu Die's condition.
Qin Sang can be sure that this slumber is not a transformation, but is related to a very rare change in the records of the witch clan, that is, the mutation of spiritual insects!
Generally speaking, the magical powers of spiritual insects are very simple.
Some people have discovered that spirit insects have the opportunity to mutate when encountering certain opportunities. The probability of spirit insects mutating is very small, but it is not uncommon in the Wu clan's long journey to control insects.
The mutation of spiritual insects occurs randomly and cannot be copied. Qin Sang did not expect to encounter an opportunity here.
