In the world of "Covering the Sky": An Analysis of the Ancient Sacred Body at the Start

Apart from black and red, the entire fiery inferno is almost entirely devoid of any other colors, and is filled with countless volcanoes of all sizes.

Volcanoes vary in size, some thousands of feet high, others only a hundred feet or so, resembling hills.

Some volcanic craters are bright red, flashing with amazing flames, while others are lifeless and pitch black.

Above the fiery inferno, a thick layer of black and red fire clouds covered the ground, which was a dark expanse covered with an unknown thickness of volcanic ash.

As Yu Yi stepped into the fiery inferno, he was immediately hit by a pungent sulfurous odor, accompanied by scorching heat waves; the temperature was far beyond what he experienced outside.

This place, where ordinary people could not survive at all, is home to many cultivators, because volcanic eruptions often bring out various fire-attribute materials.

Yu Yi saw some cultivators flying on their magical artifacts, occasionally landing to pick up things from the ground, while others plunged directly into a volcano and disappeared without a trace.

However, the fact that the Fire Hell is listed as one of the seven forbidden areas of the Great Jin Dynasty is naturally not as simple as it seems on the surface.

As they ventured deeper, Yu Yi soon arrived at the heart of the Fire Prison, where a thick red mist enveloped the entire area.

The true forbidden area lies within the red mist; very few cultivators who enter it emerge alive.

Yu Yi raised a cyan light shield around himself and plunged into the sea of ​​mist. The cyan light shield exploded with an astonishing sound upon contact with the red mist.

The red and blue spiritual lights collided continuously, creating an astonishingly powerful and increasingly intense spectacle.

In addition, divine sense is greatly restricted in this sea of ​​fog. Even Yu Yi can only sense a small area nearby, let alone those cultivators.

He hadn't walked far when Yu Yi suddenly sensed something. A cold glint flashed in his eyes, and he raised one hand, manipulating the power of fire, and flicked it forward.

A flash of red light disappeared into the red mist, and a strange roar rang out. A dark figure staggered out from the depths of the mist.

It turned out to be a demonic monkey several meters tall with red fur, but at this moment its chest was covered in bloodstains, and a fist-sized hole was constantly bleeding.

This demonic monkey was exceptionally fierce; even though it was already severely injured, it still viciously pounced on Yu Yi.

"court death!"

Yu Yi casually flicked his finger, and a beam of divine power shot out, passing through the demon monkey's head. The demon monkey's movements froze, and then it fell to the ground motionless.

As they ventured deeper into the foggy sea, the appearance of monsters became more and more frequent. In a short period of time, Yu Yi had already killed more than a dozen monsters, but none of them had transformed into human form.

Transformed demonic beasts are comparable to Nascent Soul stage cultivators. Once they gain sentience, they generally do not linger in the Fire Hell, but instead seek another place to cultivate.

Besides encountering many demonic beasts, Yu Yi also encountered quite a few fire spirits, which were extremely troublesome. No wonder Han Li in the original novel felt a headache when he encountered them.

Unlike Han Li, Yu Yi did not have the Taiyin Firebird to draw out the Sun Essence Fire, so he could only use the cumbersome method of searching inch by inch along the way, leaving no corner unchecked.

"The essence of the sun, we've finally found it!"

Not far ahead, a small, pure white winged horse, only a few inches in size, appeared. Its small wings shone with a silvery light and were formed from the essence of the sun.

Startled by the approaching figure, the Solar Flame quickly flapped its wings, sending countless silver sparks flying from them.

"I've searched this godforsaken place for months to find you, how could I let you escape?"

The spirit of the sun's fire was fast, but Yu Yi was even faster. At the same time, divine power burst forth from his body, transforming into a gigantic hand that reached out to grab it.

After being grabbed by the giant hand conjured by divine power, fear appeared in the eyes of the Sun Fire Spirit. It struggled desperately, but to no avail.

Yu Yi took out a jade bottle, put the spirit of the solar fire into the bottle, and then used a spell to seal the jade bottle to prevent the spirit of the solar fire from escaping.

"To refine the Rejuvenating Water, in addition to the two main ingredients, Cold Marrow and Solar Essence Fire, some auxiliary ingredients are also needed, but they should all be available in the Great Jin..."

After emerging from the Fire Hell, Yu Yi headed straight for the capital of the Great Jin Dynasty. It took him several days and tens of thousands of high-grade spirit stones to buy all the necessary auxiliary medicines.

Yu Yi rented another cave in Kyoto and began refining Rejuvenating Water. He had enough Cold Marrow and Solar Essence Fire to refine more than a dozen batches of Rejuvenating Water.

After two consecutive failed attempts at refining, Yu Yi finally succeeded in refining a portion of Rejuvenating Water on his third attempt.

Yu Yi had learned alchemy in Shrouding the Heavens and his skill level was not low, but the alchemy techniques in the two worlds were very different, which led to his failure in the first two attempts.

Yu Yi stopped refining the water only after all the cold marrow was consumed and the spirit of the sun's essence fire was on its last legs. He had refined a total of twelve portions of Yang-restoring water.

"This time, the Yang Water is also effective in the Four Extremes Secret Realm, and my lifespan has increased by a quarter..."

Yu Yi picked up a bottle of revitalizing water, tilted his head back and drank it. He clearly felt that his vitality surged, increasing by about a quarter.

Yu Yi then took out the Xuan Tian Immortal Vine and poured a whole small bottle of Rejuvenating Water onto it. The originally withered and yellowed vine gradually gained a touch of green.

Yu Yi could sense that the previously lifeless Xuan Tian Immortal Vine had gained a glimmer of life, but a small bottle of Rejuvenating Water was far from enough to truly revive it.

Even if we use up all ten remaining bottles of Rejuvenating Water, it won't be enough. However, as long as we restore a sliver of life, the Heavenly Palm Bottle will have a purpose.

Yu Yi took out the Palm Heaven Bottle, removed the cap, and poured a drop of the Heavenly Creation Dew onto the Mysterious Heaven Immortal Vine. The Mysterious Heaven Immortal Vine turned green at a speed visible to the naked eye.

"Seven days for one drop of the Heavenly Creation Dew is far too slow. It's a pity the Time Chamber is useless against the Palm Heaven Bottle..."

The Time Chamber is an enclosed space where moonlight cannot penetrate. Yu Yi once tried to break a hole in the Time Chamber, after which the Time Chamber disappeared.

The Time Chamber, which was originally meant to last for a month, disappeared prematurely after a hole was torn in it.

"The growth cycle of the Mysterious Celestial Vine is extremely long, requiring tens of thousands, or even hundreds of thousands of years, to flower and bear fruit under natural conditions..."

With such a long growth cycle, even with the Heavenly Bottle to accelerate ripening and a drop of Heavenly Creation Dew every seven days, it would probably take more than ten years for it to flower and bear fruit.

The most troublesome thing is that more than ten years is not the problem. The key is that Yu Yi needs to travel through time frequently, and it is impossible for him to guard the Xuan Tian Immortal Vine day after day for more than ten years.

"If all else fails, I'll have to find someone I trust to help me cultivate the Mystic Heaven Immortal Vine..."

Yu Yi considered various candidates, but Dong Yuexi was the first one he thought of. He trusted Dong Yuexi and felt at ease entrusting the Heavenly Bottle to her.

But if he takes the Xuan Tian Immortal Vine to Zhuofeng to cultivate, he will definitely not be able to hide it from Li Ruoyu. If Li Ruoyu asks about it then, how should he explain it?
