Xiao Chen and the other three followed the little fox all the way inside.
About three or four minutes later, the little fox was found spinning around in the center of the cave, seeming to want to lie down on the ground, but its pampered paws could not pull away from the hard ground, so it was spinning around anxiously.
Seeing Xiao Chen coming over, the little fox immediately showed a pitiful look and made a "woo woo..." sound, as if asking Xiao Chen for help.
"In the center of the earth?"
Xiao Chen pondered.
The little fox is more sensitive to the source of spiritual energy than he is, so he will definitely not make a mistake in judgment.
Under the center of the earth, there must be an extremely amazing spiritual source, which is the source of the rich spiritual energy here.
"Wait a moment!"
Xiao Chen shouted to the little fox, not caring whether it could understand it or not, and started to survey around the cave.
Then, he took out a few stones he had collected and placed them in appropriate locations around to construct a space frame.
"Xiaochen, what are you doing?" Ye Yufei asked curiously.
"Just make a simple closed formation!" Xiao Chen replied.
"How many stones can be thrown to set up a formation?" Ye Yufei was surprised.
"Of course, it seems like just throwing a few stones, but in fact there are many profound truths in it, such as the Five Elements and Bagua, Qimen Dunjia, and are ever-changing, which cannot be explained clearly in just a few words. And this stone is not an ordinary stone, it has special properties!"
"That's it!" Ye Yufei actually didn't understand it at all, but she could only nod her head.
"That's enough!" Xiao Chen made arrangements and said to Xiao Yingxue, "Yingxue, break that place open!"
Hearing this, Xiao Yingxue raised her little hand, and the demon sword suddenly appeared.
Qi condensed, spirit gathered, and the sword fell straight down.
boom!
The demon knife poured directly into the ground.
Although the demon sword's blade is only seventy or eighty centimeters, the sword energy extends hundreds of feet and goes straight into the center of the earth.
The core of the earth was destroyed, the entire cave was shaking, and it seemed that it would collapse at any time.
But at this time, the square formation arranged by Xiao Chen came into effect, forming an isolation space of thirty to forty square meters.
Even if the surrounding stones fall down and the stone walls collapse, they will have no impact on this space.
"Yingxue, it's almost time!" Xiao Chen reminded.
When Xiao Yingxue heard this, she held the demon sword behind her back with her little hand and pulled it out with all her strength.
Suddenly, the earth's spiritual energy, which was disturbed by the sword energy, erupted like a volcano, instantly spurting out and filling the entire space.
Because the concentration is too high, the spiritual energy slowly liquefies, making people feel like they are bathing in water.
"Yeah yeah..."
The little fox cheered instantly and jumped up and down among the three people, very lively.
"So you can make other sounds?"
Xiao Chen laughed dumbly.
It seems that this is the first time the little fox has made a sound of "yaaa". In the past, he could only "wow..." to act cute and look pitiful.
"Xiao Chen, its tail has grown!" Ye Yufei pointed at the little fox's tail in surprise.
"Well, I saw it!" Xiao Chen nodded. He noticed the changes in the little fox's tail earlier than Ye Yufei.
In other words, the main purpose of his search for this spiritual energy-rich place was to see if he could accelerate the growth of the little fox's fourth tail.
Looking at it now, the effect is amazing!
The fox cubs are an unusual breed. They may only have one tail when they are born, and then slowly grow three.
Apparently, it can evolve on its own!
It's just that the outside world lacks spiritual energy. After it ran away to the outside world, its growth slowed down. There has been no change for two years, and it was only recently that it showed signs of growing a fourth tail.
Now exposed to this aura that is ten times richer than the outside world, the little fox's accumulated growth ability explodes rapidly, and its tail changes almost every time.
"Sister, Yingxue, don't be idle, take this opportunity to absorb spiritual energy and practice, otherwise so much spiritual energy will be a waste!" Xiao Chen reminded.
"Um!"
Ye Yufei and Xiao Yingxue found a clean and comfortable place in the cave formation, and began to run the exercises Xiao Chen taught them, absorbing the surrounding spiritual energy for practice.
Xiao Chen had no intention of practicing, so he quietly helped them protect the law and looked after the little fox.
Ye Yufei and Xiao Yingxue practice, which is equivalent to seclusion. They cannot move or speak, and they focus on running the exercises wholeheartedly.
But the little fox is different. As long as it plays in the spiritual energy and jumps around, it can continuously absorb the spiritual energy, and the conversion rate is very high, which is easier than any cultivation method.
…
On the third day, the little fox's fourth tail grew ten centimeters.
On the seventh day, the little fox's tail grew ten centimeters again.
Half a month later, the little fox's four tails were basically formed and fell into a deep sleep again.
About twenty days later, the little fox woke up, which marked its successful evolution into a four-tailed spirit fox. It actually had strong spiritual power fluctuations in its body.
Xiao Chen understood that this was the awakening of the little fox's talent.
When it reaches five or six tails, or even seven or eight tails later on, it will have many special abilities.
Compared with humans, spiritual beings like it have huge advantages!
Of course, those are all things for later. For now, the little fox is just equivalent to a monk in the Qi refining stage, pitifully weak.
"Little fox, you have grown a fourth tail. Although your abilities have not increased much, your bloodline should have strengthened a lot. Come here and let me see!" Xiao Chen hooked his hand at the little fox who was playing beside him.
As if sensing the danger, the little fox's hair stood on end, staring at Xiao Chen warily, and at the same time made a cry of "Woooo...", pretending to be cute and pitiful.
But obviously, this trick was useless to Xiao Chen before, let alone now.
"Donating blood properly is good for your body and can promote blood circulation. Don't worry, you'll be fine!"
Xiao Chen said while performing a spirit-binding technique.
No matter how fast the little fox moves, he will never be able to escape from the spirit-binding technique.
"Be patient, it might hurt a little!"
Xiao Chen raised his hand to condense the wind blade, waved his hand lightly, and opened a hole in the little fox's heel.
"suck!"
Using air suction, the purest spirit fox essence blood was sucked out from the little fox's wound and put into the porcelain bottle that had been prepared.
"Woooo..."
The little fox grinned in pain and burst into tears.
At this time, Ye Yufei and Xiao Yingxue opened their eyes one after another.
Ye Yufei stood up and asked: "Xiaochen, what are you doing?"
"Take some of its blood and use it to make medicine!" Xiao Chen sealed the bottle cap, touched the little fox's head with his hand, and said with a smile, "Thank you for your hard work!"
The confinement disappeared, and the little fox jumped into Ye Yufei's arms with a "swish" sound, stuck out half of his head, and pretended to be arrogant towards Xiao Chen.
Ye Yufei touched the little fox's head and found it funny.
How could she not see that the little fox was actually not afraid of Xiao Chen at all, let alone hated Xiao Chen.
Because it obviously knew that Xiao Chen had been using its blood to refine medicine, but it never thought of escaping and usually played around with Xiao Chen.
Showing off its teeth and claws at Xiao Chen is just a way of communication between it and Xiao Chen.
