Meanwhile, Yu Tianheng was studying something beside the Ice and Fire Yin Yang Well.
Through his research, Yu Tianheng discovered that the spring water within the Ice and Fire Yin Yang Well was also a rare treasure for cultivation.
For example, the Ultimate Attribute baptism involves entering a spring after consuming the corresponding immortal Immortal Herb, where one can temper their body with the extreme energy of the Extreme Cold Yin Spring and the blazing Yang Spring.
This kind of tempering can enhance cell activity, improve the body's resistance to ice and fire attributes, and may even lead to a constitution that is immune to extreme temperatures.
In addition, it can stimulate Soul Power and potential. The energy of the spring water can stimulate human potential, help cultivators break through physical limits, and has a potential promoting effect on the improvement of Soul Power and the evolution of Martial Soul quality, laying the foundation for subsequent absorption of Soul Ring.
However, if ordinary people or ordinary Soul Master come into contact with these two types of spring water, they will be immediately frozen or burned to death by the Lie Yan.
However, if the two springs are combined through certain means to neutralize the extreme cold and heat, retaining only their original energy, they can be used effectively for cultivation. Not only Soul Master, but also martial artists can use the spring water for cultivation.
Knowing that Mu Qing was currently teaching Martial Dao arts to the soldiers of the Heaven Dou Empire, Yu Tianheng thought of refining some fused spring water to help them Flesh Refining and increase their cultivation speed in order to speed up the process.
With this thought in mind, Yu Tianheng immediately took action. He stepped onto the black stone at the junction of the Ice and Fire Yin Yang Well, his pupils reflecting the surging springs on both sides— the Extreme Cold Yin Spring on the left was shrouded in a dark blue icy mist, and the tentacle-like chill caused frost flowers to form on the rock crevices; the blazing Yang Spring on the right swallowed and spewed out crimson-gold fire waves, and the surging heat waves distorted the air into a glassy state.
He took a deep breath and struck out with both palms simultaneously, unleashing a surge of powerful True Qi.
The next moment, two spurts of water gushed out from their respective springs and came to the top of Yu Tianheng's palm.
"Condense!" Yu Tianheng shouted, clasping his hands together. At the same time, the two clumps of spring water flying in the air merged with Yu Tianheng.
But to think that you can so easily integrate the two is wishful thinking.
It should be noted that these two springs have extremely opposing properties: one is extremely cold, and the other is extremely hot. This extreme temperature difference and opposing properties cause them to repel each other when they meet, making it difficult for them to mix naturally. Just like water and oil, because of their different properties, even if they are mixed together, they will quickly separate.
Furthermore, the two energies are powerful and conflicting, causing the spring water to also have a strong repulsive quality, increasing the difficulty of fusion.
This is why, although there is no obstruction between the spring waters within the Ice and Fire Yin Yang Well, they are clearly distinct from one another.
Unless external forces intervene, attempting to merge the two is nothing short of a pipe dream.
Fortunately, Yu Tianheng had already thought of this.
He shouted, "Thunder, come!"
The next moment, thousands of silver snakes of Thunder burst forth from the void, Entanglement the merging spring water like chains.
This is not the inherent Thunder power of the Blue Lightning Tyrant Dragon Martial Soul.
Instead, it is the Nine Heavens Divine Lightning condensed from cultivating the " Nine Heavens Divine Lightning Prison Suppression Scripture," which is dozens of times more powerful than the former.
Only such power could forcibly merge the two springs containing both extreme cold and extreme heat.
In other words, only Yu Tianheng and Yu Yuanzhen in this world can achieve this.
Because the latter also cultivated the " Nine Heavens Divine Lightning Prison Suppression Scripture "!
No one else could do it, not even Tang San!
Then, the water sphere collided violently with the lightning net, first bursting out with blinding white light, ice shards and flames clashing and splashing, cold air and heat waves condensing into white mist in mid-air. He clasped his hands together, the power of Thunder hammering repeatedly, forcing the two extreme energies to compress continuously.
As the power of lightning surged, the lightning net suddenly contracted, and the ice spring and fire spring were forced to merge under extreme pressure—the dark blue and crimson gold blended together like ink into clear water, first transforming into a violent two-colored vortex, and then being constantly harmonized by the shock force of the Thunder, finally condensing into a crystal bead the size of a pigeon egg in the palm of the hand.
The surface of the bead shimmered with an icy blue and crimson gold halo, occasionally flashing with silver-white lightning patterns. Despite containing world-destroying energy, it strangely maintained its balance, quietly hovering at his fingertips.
"It's done..." Yu Tianheng's face lit up with joy as he looked at the successfully fused spring water before him, a smile playing on his lips.
This fusion spring water originates from the ultimate power of the Ice and Fire Yin Yang Well. After being harmonized by the power of Thunder, its energy becomes stable and controllable. Martial artists can refine and absorb it, which can both temper their meridians and balance their internal energy. It is a hundred times safer than directly contacting the spring water.
Of course, soul stones can also be absorbed and refined; the effect is the same.
Immediately afterwards, Yu Tianheng took out a gourd and sucked the fusion spring water floating in the air into the gourd.
Just then, Dugu Yan arrived and witnessed what had just happened. A look of confusion crossed her face as she quickly stepped forward and asked, " Tian Heng, what are you doing?"
Yu Tianheng looked at Dugu Yan and explained with a smile, "The spring water in this Ice and Fire Yin Yang Well contains boundless power, but unfortunately its attributes are too violent to be directly absorbed by the human body. So I thought of using external force to forcibly fuse the two, offsetting their violent attributes and retaining only the energy for cultivation."
"Don't be fooled by its small size; the energy it contains is equivalent to the medicinal power of twenty Origin Nurturing Pill!"
Upon hearing this, Dugu Yan was shocked. She never expected that the gourd of spring water in front of her, which could be drunk in just a few gulps, would contain such terrifying energy, enough to be equivalent to twenty Origin Nurturing Pill.
That's Origin Nurturing Pill! It was thanks to this pill that she was able to break through to level 40 in a very short time, and the medicinal power wasn't even fully absorbed when she swallowed the third one.
That's why Dugu Yan already considered the Origin Nurturing Pill to be an invaluable cultivation elixir, but after hearing Yu Tianheng's words, she realized that she still lacked knowledge.
After putting the gourd away, Yu Tianheng looked at Dugu Yan and smiled, "It seems you've successfully broken through the level 40 bottleneck, Yanyan. That's truly remarkable. It looks like we can go hunting Soul Beast and obtain Soul Ring tomorrow."
Upon hearing this, Dugu Yan waved her hand and said, "Grandpa told me you've already broken through to level 50. Compared to you, my achievements are nothing. You're much more impressive."
"By the way, I took three of the Qi-Nourishing Origin Nurturing Pill you made for me and successfully broke through to level 40. I still have seven left. Do you want me to return them to you?"
Yu Tianheng waved his hand. "No need, you can keep it for yourself. This Origin Nurturing Pill was specially made for you."
"Hmm!" Dugu Yan hummed softly, carefully storing the porcelain bottle containing the pills. Then, she and Yu Tianheng left the Ice and Fire Yin Yang Well and returned to the villa together. On the way back, the two discussed matters of cultivation, chatting and laughing together.
