One person: I, Daoist Master, am a cultivator of immortality!

"Master Dao, could you please take a look at this?" Qi Tiezui rubbed his hands together, wanting to examine the Mountain and River Seal. This was the first time he had ever seen something that could be called a magic weapon.

"Sure, this thing weighs 200,000 jin, which is about 100 tons. It's not that heavy, just the weight of a small mountain. Do you think you can lift it?"

Sun Yao tossed it in his hand and then caught it, seemingly intending to place it in Qi Tiezui's hands. Qi Tiezui immediately withdrew his outstretched hands. Although he couldn't quite believe that this small seal weighed 20 jin, Qi Tiezui felt that Sun Yao wouldn't lie to him about something that concerned his life.

To be honest, if he were to handle 200,000 jin (100 tons), it would be practically the end of his life. Qi Tiezui was extremely protective of his life, and even if there was only a 1% chance that the 200,000 jin was real, he wouldn't dare gamble with his life.

Just then, Sun Yao suddenly slapped his forehead. He had just forgotten something important: Zhang Qishan, Er Yuehong, and the others in the original mine tomb had all entered the so-called meteorite copper small world after coming into contact with this stone. Now that he had refined this feng shui stone into the Mountain and River Seal, how was he supposed to obtain the meteorite copper from Qing Wuzi's real tomb in the Yuantong Small World?

Or perhaps, due to the difference in the world, Qingwuzi's true coffin is the crystal coffin beneath this mountain and water rock? Even Sun Yao doesn't know the specifics.

Just as Sun Yao was pondering this matter, the ground suddenly shook violently, and the platform supported by eight iron chains also began to sway violently.

Immediately, a surge of earth energy erupted from the location where the feng shui stone had been. This appeared to be the earth vein feng shui energy suppressed by the core of the Feng Shui Dragon-Gathering Array. Although Sun Yao had refined the massive feng shui stone into the Mountain and River Seal, effectively dispelling the Feng Shui Dragon-Gathering Array, the feng shui power suppressed within it hadn't completely dissipated, hence its sudden burst forth.

Without a second thought, Sun Yao placed the Mountain and River Seal in mid-air. The seal emitted a golden light, successfully suppressing the surging Feng Shui power.

But the next second, Sun Yao also vanished from the platform. Along with him disappeared the Mountain and River Seal that had just suppressed the feng shui power. However, the earth-shaking tremors finally stopped, and everyone on the platform breathed a sigh of relief, clutching their chests.

At this moment, Sun Yao had arrived in another world, which was very similar to the real world, but Sun Yao knew that this was a small world constructed of Tianxing Copper.

This Celestial Copper is so magical, what is its origin? Sun Yao looked at this miniature world that seemed so real and couldn't help but sigh. But now was not the time for sighs; Sun Yao returned to the mine's entrance.

This should be the location of Qingwuzi's corpse, in the mine of the Meteorite Copper World. No, it should be called the Celestial Copper World.

After arriving in this world, Sun Yao finally understood why the Heavenly Star Copper had evolved into a world. It was because Qing Wuzi did not know how to use the Heavenly Star Copper, so he chose the method he was most familiar with: setting up a Feng Shui array to activate the Heavenly Star Copper with the power of the earth's veins and Feng Shui.

The Celestial Copper sensed the power of the earth's veins and feng shui, which is why it evolved into this small world. In other words, the abilities that the Celestial Copper can develop are all influenced by external factors.

Different forces can influence different abilities. For example, when he crafted the Celestial Torch Furnace, the Celestial Copper used to craft it developed properties beneficial to elixirs.

There were no traps or obstacles in the mines of this starry world, and he arrived at Qingwuzi's coffin without any trouble.

But here, an obstacle was already waiting for his arrival. As Sun Yao expected, what appeared in front of him was his own projection.

This was his own inner demon. The illusion of himself rushed forward without any regard for right or wrong, continuously attacking Sun Yao with the Golden Light Spell and Thunder Magic.

Sun Yao didn't rush to retaliate; instead, he continuously parried the attacks of his inner demon. However, as the battle dragged on, he increasingly realized that the inner demon's power was far inferior to his own.

Even the attacks amplified by the inner demons and imbued with the Golden Light Mantra were still able to be withstood by his physical body alone. Only then did Sun Yao realize how much he had unknowingly grown over the past three years.

Indeed, Sun Yao's inner demon was his own stagnation in strength over the past three years, or rather, his self that was only slightly stronger than he was three years ago. His lack of progress over those three years had been a constant source of frustration for him.

If his strength hadn't improved at all in these three years, he would have faced a tough battle when confronting this inner demon. But the fact that he could feel he was handling this inner demon with ease indicates that his strength had been growing unknowingly over these three years.

"I didn't realize that I've become so much stronger than I was three years ago, so why should I keep feeling sorry for myself and not improve my skills?"

Sun Yao's mindset was instantly elevated, and even his long-held, unwavering state of mind was slightly shaken. Without the slightest hesitation, Sun Yao directly took out the Mountain and River Seal from his treasure pouch.

"I don't have time to waste here with you. As my inner demon, you are quite powerful, and fighting you would be a waste of too much time. So please forgive me for being so uncivilized. Although you can imitate my face and my magic, you are ultimately just an inner demon and can never imitate my magic weapon. Mountain and River Seal, seal the mountains and rivers, suppress!"

Sun Yao immediately unleashed the Mountain and River Seal's innate divine power, "Stabilizing Mountains and Rivers," tossing it into the air. The seal suddenly enlarged in mid-air, and then the four large characters "Stabilizing Mountains and Rivers" at its base emitted a golden light.

The light instantly enveloped Sun Yao's inner demon. The inner demon tried to make a move, but found that no matter what it did, it could not escape the area covered by the light of the Mountain and River Seal.

The next second, the Mountain and River Seal fell directly from mid-air, smashing Sun Yao's inner demon to pieces.

Sun Yao looked at his shattered inner demon with lingering fear. "Although it was my inner demon that was shattered, it still terrifies me to see someone who looks exactly like me get killed. Even though I was the one who killed him, it felt like I was dying right in front of myself."

As Sun Yao spoke, his hands never stopped moving. With a flick of his sword finger, he overturned Qing Wuzi's coffin. Then, with a sharp flick of his finger, he sucked the Heavenly Star Copper fragment from Qing Wuzi's hand into his own.
