At the same time, Zhang Ling flipped his hand, and an ancient black stone mirror appeared. Several clusters of yellow spiritual power were injected into it, making the mirror surface extremely smooth. Streaks of faint blue fluorescent light emerged and quickly swam across it.
He intended to release the Water Astral Divine Lightning gathered within the stone mirror to eliminate his enemy with a single strike.
The Water Astral Divine Lightning gathered in the stone mirror possessed formidable attack power. However, once released, it would take a long time to gather and form again. To fully accumulate the Water Astral Divine Lightning, it would take at least half a year.
Therefore, a stone mirror filled with Water Astral Divine Lightning could only be used once or twice at most during a battle before exhausting the divine lightning within. If it weren't for the snake woman's ability to cast trapping illusions that were difficult to defend against, Zhang Ling wouldn't have wanted to use this ancient treasure here.
While controlling numerous attacks to surround the snake woman in a corner, he fully propelled the stone mirror in his hand, causing the gathered dark cyan lightning to constantly flicker.
The high platform they were on was protected by formations, which had previously restricted his movement, trapping him in a fog. Now, it naturally had the same effect on the snake woman. As long as she was trapped in one place, it would be difficult to evade when all attack methods were used together.
"Water Astral Divine Lightning, fellow Daoist, help me! I surrender!"
Just then, he heard the snake woman's exclamation.
The snake woman, who was trapped in the encirclement of flying swords and yellow sand, had a pale face. She was relying on the water shield, blue orbs, and silk ribbons to break free with all her might. She seemed to have a slight advantage, and if given more time, she might have been able to escape.
The snake woman had originally planned to do so, but suddenly sensed an extremely special surge of water spiritual power. She couldn't help but glance at Zhang Ling's position and discovered the stone mirror condensing black water light and faint blue electric arcs.
Being proficient in water attribute techniques herself, she instantly recognized the water-based divine lightning gathered on the stone mirror. Her expression changed drastically, knowing that it was impossible to win and that she might lose her life again.
Zhang Ling frowned slightly upon hearing the snake woman's cry but didn't pay attention. He still fully exerted the stone mirror in his hand.
At this moment, several overlapping images had appeared on the stone mirror, and in another one or two breaths, it would be able to unleash a divine lightning attack. Naturally, he wouldn't give the enemy any breathing room.
In an instant, a black light flashed on the stone mirror, and eight black rays shot out towards the snake woman.
The eight black rays dispersed around the snake woman, transforming into eight dark light mirrors, instantly surrounding the enemy.
Seeming to see Zhang Ling's determination to eliminate her, the snake woman's face turned even paler, but suddenly realizing something, she quickly cried out.
"Fellow Daoist, spare my life! I have a cultivation method here that can greatly increase your strength, and I can give it to you."
Zhang Ling sneered. He wasn't lacking any cultivation methods. With a thought, he was about to activate the eight light mirrors to release the Water Astral Divine Lightning and kill the snake woman.
But he heard the snake woman say quickly again, "Thunder Sacrifice Art, Weak Thunder Curse, Ancient Yin Thunder Method. Very suitable for cultivators who possess Water Astral Divine Lightning to cultivate. It can unleash the full power of the divine lightning."
Upon hearing the words "Thunder Sacrifice Art," Zhang Ling couldn't help but frown and temporarily halt his spellcasting.
It was said that the Thunder Sacrifice Art was a thunder technique passed down from the upper realm, and only cultivators proficient in thunder attribute techniques had the opportunity to come into contact with it. It belonged to the secret art of thunder techniques, and ordinary cultivators might not have even heard of it.
Zhang Ling knew about this ancient thunder technique because he had obtained two different attribute cultivation methods from the hidden cultivator's cave in the Kunshan Sect's base when he was exploring the desolate region. One was a wind attribute cultivation method, and the other was a thunder attribute cultivation method.
He had studied both cultivation methods. However, these different attribute cultivation methods could only unleash their maximum power with suitable spiritual roots. The book called Azure Thunder Art introduced the Thunder Sacrifice Art.
The Thunder Sacrifice Art was divided into Yin and Yang thunder, each with its own differences. But their power was very strong. The Azure Thunder Art was a cultivation method for Yang thunder.
In fact, any spiritual power also had Yin and Yang aspects. This was why some cultivators, even when practicing the same attribute cultivation method, often had some with Yang energy and some with Yin energy. Yin and Yang were also constantly transforming. Due to these many reasons, the cultivation methods in the cultivation world were ever-changing.
Water Astral Divine Lightning was Yin attribute divine lightning with a strong corrosive nature. Once it touched the body, it was like a maggot attached to the bone.
Zhang Ling had previously tried other methods to activate the stone mirror, wanting to see if the divine lightning in the stone mirror had any other changes. But other than directly releasing the divine lightning for attack and releasing eight light mirrors to continuously stack the power of the divine lightning, there were no other uses.
Although the power was already considerable, there was a long delay in casting the spell. If it were a cultivator proficient in escape techniques, it would be very easy to escape.
If there were other uses that could unleash the power of this divine lightning, Zhang Ling's heart would be somewhat moved. However, he didn't easily believe it and didn't withdraw the attack, but looked at the snake woman and said softly.
"Since you surrender, fellow Daoist, I am not a bloodthirsty person, but how can you prove what you said?"
The snake woman's face lit up upon hearing this and said without thinking, "Fellow Daoist, please see." As she said this, the faint blue orb in the snake woman's hand lit up with spiritual light.
Zhang Ling instantly became vigilant. He saw the snake woman gently tap on the orb, releasing several strands of faint blue spiritual light from it. They wrapped around her hands, and as the snake woman's hand gestures changed, a strand of dark blue electric arc actually condensed in her palm.
Seeing this, Zhang Ling was shocked. This was also a strand of Water Astral Divine Lightning, but its power was pitifully weak compared to the divine lightning in the stone mirror.
"Fellow Daoist, as long as you spare my life, I will copy a Weak Thunder Curse for you."
Zhang Ling pondered for a moment and nodded. With a thought, the flying swords and yellow sand attacking the snake woman were all withdrawn.
However, the eight light mirrors surrounding the snake woman didn't retreat at all. The black light on them became increasingly dense.
"If what you say is true, what's the harm in sparing your life?"
"Good, I hope fellow Daoist will keep your promise. I will copy the secret technique now." The snake woman looked at the eight black light mirrors surrounding her and revealed a wry smile.
If she were in another place, she would still have means to escape danger. But now, due to the backlash of her spells, she was seriously injured, and her strength could only unleash about 60%. Trapped on this arena, there was naturally not much room for maneuver.
She was also extremely depressed in her heart and had no choice but to admit defeat. The snake woman gritted her teeth and took out a jade slip from her storage bag, placing it on her forehead to copy the technique.
After a dozen breaths of time, the snake woman finished copying. She threw the jade slip towards Zhang Ling.
Zhang Ling carefully released a strand of spiritual light to hold the flying jade slip at a distance of several dozen feet. A strand of divine sense invaded it to check the contents inside.
After a good while, he withdrew his divine sense. Although his expression didn't change, he was inwardly delighted. The Weak Thunder Art recorded within did indeed have unique features. Especially the application of Yin attribute thunder techniques. Through his identification, this secret technique was real.
"This Yin Thunder secret technique is indeed good. Since you are so sincere, fellow Daoist, I naturally won't go back on my word."
As Zhang Ling spoke, he flicked his fingers continuously, and the eight black light mirrors surrounding the snake woman transformed into black rays and re-entered the stone mirror, which he put away.
