When Mu Zi began cultivating, the energy of Heaven and Earth poured towards her, absorbed rapidly by her body.
If anyone were to witness this from the outside, they would be astonished: her absorption speed surpassed even that of ordinary Heavenly Yuan masters.
This was thanks to her mastery of using spiritual power.
At this moment, a vortex, created from spiritual power, rotated above her dantian.
Accompanied by a low hum, the vortex spun rapidly, emitting powerful waves of attraction.
Under the influence of this force, the energy of Heaven and Earth surged into Mu Zi's dantian with a speed that was visible to the naked eye.
The Energy Purification Vortex!
Having studied the purchased knowledge about Rune Masters, Mu Zi deepened her understanding of the application of spiritual power.
She created this spiritual power vortex, which significantly accelerated the purification of energy.
This technique was strikingly similar to the "Energy Purification Vortex" that the Heavenly Demon-Marten taught Lin Dong in the original story. Mu Zi, not bothering with a new name, simply used the same one.
Thanks to the Energy Purification Vortex, her speed of absorbing the energy of Heaven and Earth surpassed even some top-tier cultivation techniques.
With this method, Mu Zi had abandoned the idea of learning any secret cultivation techniques.
Although techniques could accelerate cultivation, they required opening meridians, which itself consumed resources and time.
For Mu Zi, this seemed like an unjustified waste. Instead of studying techniques, she could have already broken through to the next level.
This time in Qingyang, Mu Zi obtained the Ancient Vortex Seal. This spiritual seal was a copy of the Devouring Talisman and inherently possessed the ability to absorb energy.
After studying it, she might be able to further enhance the effect of the Energy Purification Vortex, making cultivation techniques entirely unnecessary.
A vast amount of the energy of Heaven and Earth poured into Mu Zi's dantian. However, she didn't absorb it directly, but, concentrating, directed this energy into the Rebirth Seal.
As the Rebirth Seal absorbed the energy, it began to release thin streams of extremely pure Yin energy, which Mu Zi purified. The color of the icy-blue energy mass in her dantian became increasingly deep.
Hua!
After an hour of this cultivation, a crisp crack sounded in Mu Zi's dantian. The icy-blue energy mass began to spin rapidly.
In the end, with a wave of fluctuations in her body, Mu Zi successfully broke through to the late stage of Earth Yuan.
But it didn't end there. At the same moment, her spiritual power in her consciousness seemed to overcome a certain barrier and grew sharply.
Mu Zi let out a clear, prolonged cry, and powerful spiritual power poured out from her consciousness.
Boom!
The cave trembled at that moment, and an invisible wave, with Mu Zi at the center, spread in all directions.
Mu Zi frowned, concentrated, and began to control this surge of spiritual power. After a moment, the wave subsided, and silence reigned in the cave.
Feeling the spiritual power in her consciousness, Mu Zi smiled.
After this breakthrough, her spiritual power had reached a level comparable to early-stage Heavenly Yuan masters, and she was only a step away from opening her Nirvana Palace.
With her cultivation at the late stage of Earth Yuan, she could fight any opponent below the Yuan Dan level!
Moreover, after her spiritual power was enhanced, she could finally use the Icy Mysterious Iron from her Qian Kun bag.
Mu Zi took out the Icy Mysterious Iron. Earlier in Yancheng City, she had already shaped it into a short sword. Now, all that was left was to engrave runes on it using her spiritual power to turn it into a weapon capable of withstanding spiritual force.
After her recent breakthrough, her spiritual power allowed her to try creating more powerful runes.
However, Mu Zi didn't immediately begin forging, choosing a more cautious approach.
She had recently destroyed several bandit camps, and their loot had naturally supplemented her personal treasury, including several valuable items.
Mu Zi rummaged through her Qian Kun bag and extracted several rare metals.
Although their value was inferior to the Icy Mysterious Iron, they significantly surpassed ordinary steel tempered a hundred times and could withstand stronger runes.
Mu Zi decided to practice on them first to improve her skills before moving on to the Icy Iron.
Another hour passed.
Mu Zi focused, and a short sword suddenly flew out of her hands. Under the control of her spiritual power, it made several circles around the cave and hovered before her.
It was a dazzling white short sword, adorned with ten runes on the blade. When the runes lit up, the sword was covered with a thin layer of blue frost.
"How beautiful!" Mu Zi exclaimed, extremely pleased.
Though the power of this sword was not yet clear, its appearance had already won her heart.
Power is temporary, but beauty is for a lifetime!
At the same time, its might was clearly not small. The Icy Iron constantly exuded coldness, but when Mu Zi activated the runes on the blade, this coldness became terrifying.
With this sword, if she were to face Li Yan again, she could have cut him down with a single blow.
When fully activated, this sword was so strong that opponents below the Yuan Dan level could only dodge its edge.
But the most important thing was that this chilling cold had the ability to freeze spiritual power, giving her an advantage against Rune Masters.
Having obtained the Ancient Vortex Seal, Lin Dong would likely soon create a natal spiritual seal and become a first-seal Rune Master. Then, thanks to his spiritual power, he would be able to fight against Yuan Dan masters.
However, if Lin Dong decided to stand against Mu Zi, his spiritual power would be far less effective.
Lin Dong: "And why would I do that?"
Mu Zi gazed at the blue short sword before her, and a spark of inspiration flashed in her mind.
"The extreme cold of the source conceals the icy soul, and the thousand-year-old ice forms the body of the sword," she said.
"This sword will be called the Icy Soul Sword!"
Putting away the Icy Soul Sword, Mu Zi looked outside the cave.
"Time to play with some demonic beasts," she said.
Demonic beasts: "Stay away from us!"
Half a month later, in a forest near Qingyang City.
Mu Zi had just finished her "game" for the day and was now sitting on the top of a large tree, contemplating the landscape in the distance.
Suddenly, on the dirt road behind the forest, a cloud of dust rose. A group of people was fleeing in a panic, and judging by their direction, they weren't far from Mu Zi.
She used her spiritual power to investigate and noticed that their clothes bore the emblems of the Lin clan.
At the center of the group, several guards surrounded two women who seemed to hold high positions in the Lin clan.
One of the women, with a graceful figure but in simple clothing, looked anxious, yet her face still held a gentle refinement. Based on her memories from her past life, Mu Zi guessed who she might be.
Lin Dong's mother, Liu Yan.
At that moment, a noise came from the forest. A group of people, surrounded by a powerful aura of killing intent, appeared in Mu Zi's spiritual power's perception.
Their leader, whose Yuan Power fluctuations made her gaze freeze, was particularly noticeable.
Late stage of Heavenly Yuan!
Apparently, this was the head of the Xie clan from Qingyang, Xie Qian.
Mu Zi frowned slightly, not wanting to get involved in other people's business.
However, the people of the Xie clan unexpectedly noticed her on top of the tree and, without saying a word, shot an arrow at her.
Seeing this, Mu Zi's face instantly darkened.
