Fang Zhixing was not averse and responded, "Go rest, I’ll go first."
Yue Su replied, "You have been fighting for a long time before I arrived, and your physical strength is more depleted than mine, you rest first."
Fang Zhixing hesitated for a moment, then nodded and said, "Alright, please be careful, Miss."
Having said that, he walked to a big tree, sat down cross-legged, and closed his eyes to regulate his breath.
Yue Su stood in front of him, confronting a group of skeletons.
It had to be admitted that her hand technique was bizarre and elusive, the Evil Yin Power emitted from her palms was extraordinarily terrifying, resembling the true energy of cold ice, freezing skeletons one after another into ice sculptures, which then shattered into icy fragments with a slight touch.
After resting for half an hour, Fang Zhixing’s physical strength had largely recovered, he opened his eyes and carefully observed Yue Su.
"Her strength is not weak, stronger than those in the late stage of the Nine Ox Realm, but not yet at the peak of the Nine Ox Realm," he judged roughly in his mind.
Of course, having not personally experienced how formidable the Evil Yin Power was, he couldn’t specifically assess Yue Su’s actual combat power.
But merely from the speed at which Yue Su killed skeletons, she was better than him!
"Miss Yue Su, you rest," he said.
Fang Zhixing stood up, his figure flickered, and he moved beside Yue Su.
"Alright, thank you," she said.
Yue Su was panting, with sweat soaking her white dress.
She quickly retreated under the big tree and began to regulate her breath.
Fang Zhixing took a deep breath and focused on killing skeletons.
This time, he summarized his previous combat experience and instead of using the Heavenly Net Blood Transformation Skill, he switched to using Jade Qilin Break.
Among the five Demon Transformation Martial Arts he mastered, each had its characteristics.
The Blood-Drinking Demon Sword was extremely fierce, but it consumed a lot, not suitable for prolonged battles.
The Hundred Poison Divine Skill and the Six Void Mysterious Skill were not very effective against skeletons.
The Heavenly Net Blood Transformation Skill, although equipped for both offense and defense, consumed almost as much as the Blood-Drinking Demon Sword without blood replenishment.
On the other hand, the Jade Qilin Break, a Mysterious Turtle Series Martial Art, focused on defense and endurance. As for the insufficient attack power, he naturally used the Dragon Slayer Treasure Saber to compensate.
Fang Zhixing’s figure rapidly enlarged to five meters, covered with a layer of jade scales, holding the Dragon Slayer Treasure Saber in his hand, he deployed the Iron Bamboo Divine Sword Technique, quickly killing skeletons one after another.
As a result, his speed of killing enemies also increased significantly, blocking the waves of skeletons’ assaults.
Before long, an hour had swiftly passed.
Yue Su stepped in again, and Fang Zhixing rested.
The two alternated, two times, three times, four times...
Fang Zhixing was resting, Yue Su was killing skeletons.
Suddenly, an anomaly occurred!
The ground shook violently, like a major earthquake, shaking intensely.
Fang Zhixing quickly got up, puzzled.
Yue Su also frowned, confused.
Looking around, all the skeletons had stopped their attacks and were retreating backward, disappearing into the darkness.
Not far away, thick dust rolled towards them, seeming to hide something.
Yue Su pulled out a fire striker from her bosom, lit it, and tossed it over.
The fire striker flew through the forest, dispelling the darkness.
The fire striker hit something and bounced back, falling to the ground.
Fang Zhixing looked intently, his pupils involuntarily constricted sharply.
He saw a tall stone door rise from the ground, towering in front of the fire striker.
Yue Su’s expression changed abruptly, and she blurted out, "Where did this stone door come from? There wasn’t supposed to be anything there before, right?"
Fang Zhixing hesitated, then asked, "Shall we go over and take a look?"
Yue Su hesitated, nodded and said, "Alright."
She cautiously walked over, always ready and on high alert.
Fang Zhixing did the same.
The two quickly reached three yards from the stone door, examining it carefully by the light of the fire.
The stone door was about ten meters wide, consisting of two doors.
The door on the left was carved with a sun totem.
Correspondingly, the door on the right had a moon totem carved on it.
Fang Zhixing looked up and was suddenly struck by the immeasurable height of the stone door, which seemed to reach up into the clouds, disappearing into the night.
Yue Su also noticed that the stone door seemed endlessly towering.
Fang Zhixing couldn’t help but ask, "Has no one in the Wild Forest ever seen this stone door?"
Yue Su shook her head and said, "If they had, given my position in the Extreme Yin Sect, it’s impossible that I wouldn’t know."
After pondering for a moment, Fang Zhixing picked up a broken bone from the ground and hurled it with great force.
The bone dashed away, hitting right in the center of the stone door.
In an instant, a humming noise!
The stone door quivered, shaking off a great amount of dust.
"Hey, there are characters below!"
Yue Su suddenly raised her hand, pointing to the base of the stone door, about a meter off the ground.
As the dust fell off, two lines of text were revealed.
"Rule One: This door will only reveal itself after a sufficient number of skeletons are killed."
"Rule Two: The door will only open if a man touches the sun and a woman touches the moon."
After reading, Fang Zhixing suddenly came to a realization.
