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

As Sun Yao spoke, he took a deep breath, as if he could draw spiritual energy into his body with a single inhale. But in reality, such an action was ineffective. To allow spiritual energy to enter one's body, one needed to circulate one's cultivation technique to absorb spiritual energy into one's Qi Sea and Snow Mountain.

"Kid, what are you doing? I've never heard of absorbing the spiritual energy of heaven and earth just by breathing."

"Hehe, I was just being silly to lighten the mood. Of course I know that the spiritual energy of heaven and earth can't just enter the body like that. I've cultivated to my current level, do you think I don't understand these things? Alright, shouldn't we be discussing how to enter this Heavenly Pool? Do you have a way to get me down, or should I use the Golden Light Spell to go down?"

"Since I said I would let you enter the Heavenly Pool, I naturally have a way to help you enter it. This pearl is a water-repelling pearl, a precious pearl taken from a thousand-year-old clam. With it, you can move freely in the water, just as well as on land, without affecting your strength at all."

As he spoke, Grandpa Liu spat out a precious pearl, which was a deep blue color and about the size of a ping-pong ball. Sun Yao took it and examined it closely. "Hmm, not bad. You knew to wrap it in spiritual energy so that your saliva wouldn't get on it."

"Hey, you brat. How dare you talk like that? If you dare to anger me again, I won't give you this water-repelling pearl today."

"No way! I've got my hands on this bead, so there's no way you can go back now. With this bead, I can roam freely in this Heavenly Pool. Second Master, don't worry too much about me. I'll be back in an hour."

After Sun Yao finished speaking, there was a splash, and he used his second grandfather's head as a diving platform to jump directly into the Heavenly Pool.

"Kid, I haven't finished speaking yet! After entering the Heavenly Pool, the fire dragon isn't the real threat. The real threat is the fire vein beneath the Heavenly Pool. Be careful!"

Before Grandpa Liu could finish explaining the precautions, Sun Yao plunged into Tianchi Lake. Grandpa Liu could only shout loudly from the shore, hoping Sun Yao could hear him.

But once Sun Yao plunged down, he couldn't care less about it. In the time it takes for an incense stick to burn, Sun Yao had already descended a hundred meters, but even after descending a hundred meters, he still hadn't reached the bottom of the Heavenly Pool. However, as he descended a hundred meters, the impact of that plunge had long been exhausted, and even this hundred-meter distance involved some additional movements on top of that plunge.

Once he reached the 100-meter depth threshold, Sun Yao would have to swim to descend further. However, swimming was too slow, so Sun Yao chose another method—rocket propulsion.

Ordinary flames cannot burn in water, but Sun Yao possesses the Golden Flame. He placed his hands behind his back, then, like Iron Man, unleashed flames from his palms to accelerate himself towards the bottom of Tianchi Lake. This method proved to be fast enough. However, it's not something the average person should attempt, as even Sun Yao, with his exceptional physical abilities, felt dizzy and disoriented from the pressure.

Sun Yao descended over 200 meters at an extremely fast speed before finally reaching the bottom of Tianchi Lake. However, to his surprise, the bottom of Tianchi Lake wasn't as dark as he had imagined; on the contrary, it was remarkably bright. At around 200 meters, the water was already dark and gloomy. But at a depth of over 300 meters, the lake was unusually bright.

However, Sun Yao quickly realized the reason why the bottom of the Heavenly Pool was so bright: it was due to the earth fire veins that covered the bottom of the pool. These earth fire veins were spread throughout the bottom of the Heavenly Pool, and each of them was exposed on the surface.

These fiery veins resemble magma yet are different from it. They did not solidify because of the water in Tianchi Lake; instead, they became active at the bottom of Tianchi Lake, creating natural lighting.

Having figured all this out, Sun Yao began searching for the Fire Dragon. The Fire Dragon at the bottom of this Heavenly Pool should be the same one that fell into the Yingkou River years ago, but it was highly unusual that only its skeleton remained two days after the fall. Sun Yao was eager to know what it looked like now, which was why he descended to the bottom of this Heavenly Pool.

Unlike ordinary bowl-shaped or cone-shaped lakes, Tianchi Lake is formed from a volcanic crater, so its bottom is almost flat. In other words, its bottom is similar to a plain, which makes Sun Yao's search more difficult. However, none of this is a problem for him, who possesses double pupils. Even illusion arrays are commonplace to him, let alone the indistinct environment.

Sun Yao's search for the Fire Dragon went very smoothly. In about half an hour, he successfully located it on the plain at the bottom of Heavenly Lake. The Fire Dragon wasn't difficult to find; it lived near the earth's fire veins on the plain at the bottom of Heavenly Lake. Simply follow its trail along the earth's fire veins, and it would be found in no time.

However, the fire dragon that came into view took Sun Yao by surprise. This dragon had two horns on its forehead, two feet on its belly, and its scales were a pale gold color. Its head and back were covered in mane, the same color as its scales. This fire dragon looked nothing like a dragon; it was practically indistinguishable from one.

Moreover, in his imagination, a fire dragon should be mostly red. But this fire dragon was pale gold, quite different from his preconceived notions. However, the fire dragon's next actions convinced Sun Yao that it was indeed the fire dragon he was looking for.

This fire dragon actually opened its massive mouth and began to absorb the magma veins at the bottom of the Heavenly Pool, swallowing the magma directly into its mouth. Judging by its unscathed appearance, it would be strange if it weren't a fire dragon.

"So this is the Fire Dragon. Stereotypes really do kill people. I thought Fire Dragons were all red, but it turns out they are golden."

As Sun Yao spoke, he strolled towards the fire dragon. By now, he probably understood why the fire dragon would fall after transforming into a dragon. It was because the fire dragon was already nearing the end of its lifespan, and the reason it was able to survive until then was entirely due to absorbing the fire veins of the Heavenly Pool to prolong its life.

Given his current wretched state, it would be a miracle if he succeeded in transforming into a dragon. The only reason he can still be barely alive is because he absorbed the fire energy from the earth fire veins at the bottom of the Heavenly Pool.
