125: The Desert of the Underworld! The Frigid Spring of the Heavens!

Hot!

Rolling heatwaves were endless.

Every sand dune was like a red-hot iron mountain, emitting heat that could dry a person out.

If it were just this abnormal heat, Su Yang, at the Peak Late Golden Core Stage, and Bai Lingxi, at the Late-stage Soul Transformation Peak, would not have felt it significantly.

But this was the Yellow Springs Desert.

True Qi was uncontrollably draining away.

They couldn't even circulate their cultivation to slow down the process of True Qi loss.

Because once they circulated their cultivation, the True Qi would drain even faster, leading to an increased consumption.

They could only let the True Qi within their bodies drain.

They relied solely on their Physical Bodies to resist the abnormally scorching wind and sand of the Yellow Springs Desert.

"Originally, I wanted to find a city closest to the Heavenly Extreme Cold Spring as a starting point to enter the Yellow Springs Desert."

"With what you've done, even I don't know how long it will take us to find the Heavenly Extreme Cold Spring."

Bai Lingxi complained, enduring the scorching wind and sand.

Su Yang said, "Sect Master Bai, if you trust me, it's not too late for us to go back the way we came now. I promise I won't contact them again. We can just follow your original plan, inquire for information in the surrounding cities, and then go look for the Heavenly Extreme Cold Spring."

Bai Lingxi rolled her eyes at him.

Even though she knew through the Five Thunder True Word Incantation that Su Yang was speaking his mind, she wouldn't take that risk.

Su Yang not contacting them didn't mean that those two masters wouldn't come looking for them after they left.

If they were caught by those two Grand Elders, whose strength far surpassed his, then all initiative would be taken from them, and they would be at their mercy.

This risk, to her, was clearly greater than the risks posed by the Yellow Springs Desert.

"Since we're already in, just follow me and keep going."

Bai Lingxi replied.

Su Yang was helpless, knowing he had aroused her deeper vigilance.

However,

Su Yang wasn't too worried.

As a native of the Yellow Springs Country, Bai Lingxi must have a sufficient understanding of the Yellow Springs Desert to have the confidence to choose to go deeper.

With her as a guide, they certainly wouldn't die here.

Su Yang followed closely beside her.

He casually asked, "There are no landmarks in this desert. Are we just going to keep walking aimlessly like this?"

Bai Lingxi said, "The Heavenly Extreme Cold Spring absorbs all the Spiritual Qi within the Yellow Springs Desert. So, the True Qi that escapes from us is a beacon. Just keep following the direction the Spiritual Qi drifts, and eventually, we will find the Heavenly Extreme Cold Spring."

"So that's how it is!"

"No wonder Sect Master Bai is so confident."

As Su Yang was speaking, his foot kicked a hard stone.

He looked down and saw part of a shriveled Spirit Beast corpse buried under a sand dune.

The reason he immediately confirmed it was a Spirit Beast corpse was because the fur was still on it.

Bai Lingxi had clearly entered the Yellow Springs Desert before and said, unfazed, "The outer reaches of the Yellow Springs Desert are littered with countless Spirit Beasts that mistakenly entered it. They all died from having their Spiritual Qi drained. Besides Spirit Beasts, there are also many human mummies buried in the sand dunes in the outer reaches. They are buried quite deep, and you've probably stepped over quite a few along the way."

Su Yang had no doubt about her words.

This Yellow Springs Desert could definitely kill any Spirit Beast or human who entered without preparation!

Indeed.

For the next three days, Su Yang followed Bai Lingxi deeper into the desert, encountering many large Spirit Beast mummies half-buried and half-exposed in the sand dunes along the way.

Among them were mummies of giant flying Spirit Beasts that had fallen from the sky, unable to fly over the Yellow Springs Desert, forever remaining in the yellow sand.

After the fifth day of deep penetration into the Yellow Springs Desert, the mummies of Spirit Beasts became increasingly rare.

By the seventh day, no more signs of death were seen.

But Su Yang knew very well that this didn't mean the danger had disappeared; rather, it meant greater danger.

Fortunately, Su Yang's sea of consciousness contained a large quantity of purple gold pills for consumption, and Bai Lingxi, as a Sect Master, also had a large quantity of Medicinal Pills she could take.

The True Qi within their bodies was constantly consumed and constantly replenished.

This allowed them to continue deeper into the Yellow Springs Desert.

They continued to go deeper for more than three months.

Su Yang didn't know how far he and Bai Lingxi had actually walked.

Nor did he know their current location within the Yellow Springs Desert.

He could only feel that the deeper they went into the Yellow Springs Desert, the higher the temperature became.

The first month was like walking on a red-hot iron plate.

The second month was like being forged by invisible flames.

By the third month, the surrounding temperature was as exaggerated as a Pill Furnace; anyone without enough True Qi to support their body would be refined in a matter of minutes, it was that terrifying.

However,

Just as the temperature of the Yellow Springs Desert reached its Peak, the surrounding temperature miraculously began to drop.

"Is it my imagination?"

Su Yang stood on a sand dune at this moment.

He spread his arms and clearly felt that the temperature on his left and right differed by more than 10 degrees.

Although this difference was insignificant in the terrifying high temperature, this change in cooling meant that the surrounding environment had changed, perhaps they were already close to the Heavenly Extreme Cold Spring?

Su Yang's guess was correct.

Bai Lingxi visibly breathed a sigh of relief after feeling the temperature change. She said, "The temperature has dropped, which means we have reached the critical line where the Heavenly Extreme Cold Spring and the Yellow Springs Desert influence each other. We should be able to see the Heavenly Extreme Cold Spring in about a month's time from here."

"Finally, we're almost there!"

Su Yang was even more overjoyed.

The Innate First-Grade Water Spirit Root was already nearby, and now the Heavenly Extreme Cold Spring was about to be found.

He was about to enter the Nascent Soul Stage, about to step onto a higher platform; all the hardships he endured were worth it at this moment!

"Let's keep going!"

Bai Lingxi took a Medicinal Pill to replenish True Qi, put it in her mouth and swallowed it to supplement her consumption.

Su Yang also took a purple gold pill from his sea of consciousness and swallowed it.

The two continued to follow the direction of the escaping Spiritual Qi.

Since crossing the critical line, the temperature had been continuously dropping, and the speed of the drop was very fast.

Three days after crossing the critical line, the temperature reached the most comfortable level for the human body. Although all that could be seen was yellow sand, the perceived temperature felt as comfortable as a spring breeze.

But this comfort was very short-lived.

For each day they continued forward, the temperature dropped sharply with an incomprehensible magnitude.

When they had gone deeper for another half a month, the surrounding temperature was already so low that even the yellow sand was frozen brittle. With every step, the granular yellow sand would immediately crumble into fine powder due to the external force.

There was no wind.

No snow.

And no cold fog.

What met their eyes was still a desert.

But the surrounding temperature was rapidly dropping as they got closer and closer to the Heavenly Extreme Cold Spring.

At the same time, because they were getting closer and closer to the Heavenly Extreme Cold Spring, the speed at which True Qi was being drawn away also increased, and both Su Yang and Bai Lingxi had to take Medicinal Pills to replenish True Qi with increasing frequency.

They continued to follow the direction of the Spiritual Qi for another half a month.

Su Yang had already reached the point where he had to maintain his internal True Qi at no less than two-thirds.

If his True Qi dropped below two-thirds, his Physical Body would simply be unable to withstand the incomprehensibly terrifying low external temperature.

Even Bai Lingxi had to maintain her own True Qi at above one-half at all times to withstand the deadly low external temperature.

They endured the extreme cold and walked for another three days.

Finally, Su Yang saw a clear spring amidst the yellow sand...
