I became the Open Source Saint Ancestor in the Cultivation World

"Although I don't want to fight you, since you've put it that way, I have no choice but to play along."

Ma Ke's voice was calm, but as soon as he finished speaking, he took the initiative to act.

He didn't want to linger here too long, lest he attract other people and cause even more trouble.

He quickly formed a hand seal, and then a beam of spiritual light struck the Fire Cloud Cone, which spun rapidly and hurtled straight at Shi Ce.

Compared to his previous opponents, Shi Ce's expression was noticeably more solemn. Without the slightest hesitation, he quickly formed several hand seals, and a beam of spiritual light struck the sword, causing the giant sword to intercept him.

A cone and a sword clashed in mid-air, radiating light and sparks flying.

At the same time, Shi Ce raised his hand and summoned a silver mirror.

A beam of light struck the mirror, and the mirror instantly swelled to a size of ten feet, like a full moon, emitting a bright light.

He quickly formed hand seals and unleashed another burst of spiritual light. The mirror surface shimmered with light, and then a dense stream of silver light shot out rapidly.

While he was casting the spell, Ma Ke did not hesitate and quickly and swiftly made a hand seal.

A beam of light struck the fire dragon, which let out a silent roar, its size increasing several times over. It then swiftly flew in front of him, completely obscuring its front.

Faced with the incoming silver light, the fire dragon opened its huge mouth and spat out fireballs the size of fists.

Fireballs and silver light collided, emitting a series of hissing sounds. One after another, the silver light was melted, and fireballs exploded in the air, like fireworks in full bloom, beautiful yet full of killing intent.

Upon seeing this, Shi Ce quickly projected another beam of light onto the mirror, making the silver light even denser.

Not to be outdone, Ma Ke also unleashed a burst of spiritual light upon the fire dragon, unleashing a continuous stream of fireballs.

"You want to compete with me in internal energy?" Shi Ce sneered inwardly.

Although fire attribute has a certain restraining effect on metal attribute, that is only when the cultivation levels of both parties are roughly the same.

Having spent over a hundred years in the Qi Refining stage, my greatest advantage, besides a deeper understanding of spells and more convenient use of magical artifacts, is my more abundant true Qi.

He didn't believe that any Qi Refining Perfection cultivator could rival him.

Now that the opponent has chosen to fight a direct battle to deplete his true energy, isn't that courting death?

What he didn't know was that Ma Ke's true energy, except for the trace at the first level of Qi Refining, was all cultivated from the "Open Source Limitless Skill," making it extremely pure and thus more durable.

Although he is only at the ninth level of Qi Refining, not yet at the peak of Qi Refining, the true energy of the three fellow disciples who died at the hands of Qimen Valley is still stored there.

Moreover, he never expected that he was facing an old monster who had been at the peak of Qi Refining for over a hundred years.

Therefore, Ma Ke was confident that he would not lose to his opponent in terms of the strength of his internal energy.

Besides, in addition to his fire-attribute true energy, his earth-attribute energy is also quite strong, and he can't afford to waste it now.

So he quickly made a few hand seals, and his hands swiftly grabbed at the ground. Thick earthen walls rose up from the ground in a rush, and the top of the walls rolled inward to completely close up.

As a result, Shi Ce was trapped in a completely sealed earthen dungeon.

But Shi Ce wasn't worried at all, because this wouldn't sever his connection with the magical artifacts outside. However, it would affect his ability to continuously inject spiritual power into the artifacts.

So he flipped his palm and produced a golden seal the size of his palm.

With swift hand gestures, a beam of spiritual light struck the golden seal, causing it to instantly swell dozens of times in size before crashing violently into an earthen wall.

With a loud bang, the ground shook violently, and the earthen wall cracked instantly.

Ma Ke waved his hand and summoned a jade fan. With the infusion of spiritual light, the jade fan swelled to a size of ten feet.

Then it kept fanning in the air, and a rain of fire poured down, pouring onto the earthen wall, which quickly solidified and became even stronger.

Ma Ke quickly cast several spells, continuously increasing the thickness of the earthen wall.

Boom boom boom...

Shi Ce manipulated the golden seal to smash the earthen wall more than a dozen times, but it remained unmoved, and his expression immediately turned somewhat ugly.

Just then, he felt a tremor beneath his feet. He quickly turned the golden seal around and smashed it against the earth spikes that had sprung up from the ground. The earth spikes instantly turned into dust.

"Let's see how much true energy you've used up." Shi Ce kept manipulating the golden seal to smash the earthen wall and ground spikes.

With such a huge expenditure, Ma Ke's earth-attribute true energy was quickly depleted.

After all, his earth attribute cultivation was only at the seventh level of Qi Refining, and he had no reserves and could not get replenished.

Without the continuous infusion of spiritual energy, the earthen wall became fragile and was smashed to pieces by the golden seal with a loud bang.

Shi Ce leaped forward, and with a wave of his hand, the golden seal hurtled directly towards Ma Ke.

Ma Ke quickly formed a hand seal, then pushed his palm forward sharply. A fiery palm flew out and grew more than ten times its original size, catching the golden seal that was hurtling towards him.

Shi Ce let out a cold shout, and a beam of spiritual light struck the seal. The golden seal shone brightly and pressed down sharply.

Not to be outdone, Ma Ke also unleashed a burst of spiritual light onto the back of his palm, making his hand even more solid. Then, he thrust upwards with a sudden force, pushing the golden seal back a bit.

"Heh heh, here we go again." Shi Ce sneered inwardly as he saw Ma Ke continue to exert his inner energy.

However, he also knew that this was probably the only way for both sides to decide the outcome.

Both of them had launched several fierce attacks on each other, but they were basically evenly matched.

Since we can't win in terms of attack, we can only compete in terms of endurance.

Thus, the two sides went back and forth, each believing they had the advantage in terms of abundant true energy, and continuously mobilized their true energy to transform it into spiritual power, frantically pouring it into magical artifacts and spells.

About fifteen minutes later, both of them had the same question in their minds: "Why is his internal energy so powerful? It doesn't make sense."

"Hehe, let's see how long you can hold out," Shi Ce said casually.

Ma Ke's heart sank slightly. At this moment, his true energy was indeed greatly depleted, not to mention the earth attribute energy, which was already almost depleted.

The deepest fire attribute has not only been exhausted by the reserves of his three fellow disciples, but he himself only has about 30% left.

However, he remained calm and instead unleashed several beams of spiritual light, further increasing his spiritual power output.

Shi Ce's expression hardened slightly, and he suddenly asked, "May I ask how old you are this year?"

"How old are you?" Ma Ke's heart skipped a beat, then he chuckled, "Would you believe me if I said I'm almost a hundred?"

"Believe it, why wouldn't I?" Shi Ce laughed heartily, his heart set on it.

Because even if you're almost a hundred years old, so what? I've been at the peak of Qi cultivation for over a hundred years.

If you're going to compare your background and depth with me, you're still too green.

He then strengthened his resolve and continued his standoff with Ma Ke.
