Mortals, and even my disciple Han Li, don't mess with me!

"Very well! Then I, Wei, will grant your wish, fellow Daoist."

Wei Wuyai immediately burst into laughter, and then released a torrent of divine power.

This divine power, like a tangible painting, roared towards Wu Yun in the air, as if a torrent or tsunami was about to engulf and devour him.

If an ordinary early-stage Nascent Soul cultivator were faced with such terrifying divine power, they would probably have fled in terror long ago. However, Wu Yun not only showed no fear, but calmly released his own divine power.

"boom!!!!"

This was a deafening roar that shook heaven and earth, instantly turning all the petals on the top of Haoyang Mountain into dust.

At the same time, gusts of wind howled out from around the two of them, accompanied by a series of deafening explosions like firecrackers.

Especially the streaks of white air completely engulfed the two figures in the air.

However, upon closer inspection, one can still vaguely discern two motionless black figures.

As time passed, these two powerful divine energies caused the entire sky to be struck by thunder, erupting with unprecedented thunderous roars.

The sound was so loud that it could be heard clearly for hundreds of miles around, and it was deafening.

"boom!"

This strange phenomenon lasted for about fifteen minutes before abruptly ending with a deafening roar. The phenomenon then completely vanished without a trace.

"I didn't expect that you, fellow Daoist, would have a stronger divine sense than I do, even though you've just advanced to the Nascent Soul stage. It seems that apart from that old Daoist Zhiyang, no one can surpass you in terms of divine sense."

Wei Wuyai said with a smile, but his aged face was pale.

At the same time, there was still a lingering sense of shock and horror.

"Is the power of Supreme Yang's divine sense very strong?"

Upon hearing this, Wu Yun became curious and pressed for more information.

"Of course, that old guy's spiritual power is the strongest among the three of us. This is related to a divine ability he cultivated in his early years. That divine ability amplifies spiritual power, but it has a significant drawback. That is, every time he uses it, he can't use his full spiritual power to fight for a long time afterward. So, unless it's absolutely necessary, that old guy won't use it lightly."

Wei Wuyai made no attempt to hide anything and told him the truth as always.

"I see, thank you for informing me, Brother Wei."

"From now on, there's no need to call me Brother Wei anymore. Just call me Old Man Wuyai. After all, I've lost two matches in a row, and according to our previous bet, I should be taking you as my master."

In response to Wu Yun's address, Wei Wuyai smiled nonchalantly and then bowed to Wu Yun with his hands clasped in greeting.

Upon seeing this, Wu Yun was stunned and stood frozen in place, somewhat at a loss for what to do.

But then he remembered the system's familiar yet somewhat damned voice.

"The 'Teacher-like Immortal Cultivation System': The disciple Wei Wuyai has been accepted. Please select your reward."

Upon hearing that familiar voice, Wu Yun frowned slightly.

It's really hard to choose.

He was somewhat aware of the conspiracy between the Mulan clan and the Yinluo Sect, but not in great detail.

The Calamity Poison Body is a constitution that suits Wei Wuyai but not him, and there is a risk of backlash, so it is really unsuitable.

As for the final supreme treasure, the Demon Blade Blood Sky, this treasure comes from Eternal Life.

It was a treasure that could be upgraded to a Dao artifact, but Wu Yun actually had some concerns about such a treasure.

Because its demonic nature is so strong, Wu Yun is not confident that he can control it with his current strength.

If one were to be devoured by it, the consequences would be unimaginable. One could very well become a bloodthirsty demon, ultimately leaving a huge future threat to the entire human realm.

Although he was neither a saint nor a saint, Wu Yun was still somewhat hesitant about this matter.

"Brother Wei, you're joking. It was just a joke, don't take it seriously."

After temporarily setting aside this somewhat troublesome choice, Wu Yun then turned his attention to dealing with Wei Wuyai.

"Alright! Let's drop this matter then. However, fellow Daoist, don't forget what you promised Wei."

Wei Wuyai was quite satisfied with Wu Yun's answer, but still offered a reminder.

"Of course. If the Mulan clan really invades the Tiannan cultivation world, I will do my best to help. However, you must also give me enough benefits. For example, you must find a way to collect some of the materials I gave you before. These are my conditions. The more materials you collect, the more effort I will put in. So whether I go all out depends on your sincerity."

Wu Yun still had a smiling expression on his face.

"I will do my best. With your help, I believe the Mulan clan's plan will not succeed this time."

Wei Wuyai was neither surprised nor angry at Wu Yun's attitude; on the contrary, he was very happy.

"By the way, Brother Wei, how much do you know about the Fallen Demon Valley?"

Wu Yun suddenly changed the subject.

"This is the most dangerous place in the south. Are you perhaps interested, fellow Daoist? If so, please take my advice: it's best not to go, as it is far too perilous. I went there once years ago in an attempt to break through to the late Nascent Soul stage. Unfortunately, I gained nothing and almost lost my life. It took me over a hundred years to recover, which greatly prolonged the time it took to break through to the late stage."

"If it weren't for this reason, I might have already broken through to the late-stage Great Perfection realm."

At this point, Wei Wuyai's tone was full of regret.

"That's a real shame!"

Wu Yun nodded and said with considerable regret.

"Actually, the Ghost Spirit Sect is currently researching how to enter the Fallen Demon Valley, so I hope you can pay more attention to it. Perhaps they will figure out a way to enter safely. If they do, we can join in the fun. In any case, although it is dangerous there, there are still many good things. If we can get them, we might be able to advance further."

Wu Yun continued.

"What you say is true, fellow Daoist. I will send someone to keep an eye on it."

Wei Wuyai did not refuse Wu Yun's suggestion and readily agreed.

"Besides this matter, there is another person who needs your attention, fellow Daoist. This person's identity is somewhat special. He is a living descendant of the once number one mad cultivator in Tiannan, the Venerable Cangkun, and also the only descendant to reach the Nascent Soul stage. He is the Marquis of Nanlong. I hope you can pay more attention to him, because if nothing unexpected happens, he should be searching for the Venerable Cangkun's remains. If we can arrive sooner, we might also find something."

Wu Yun then went on to talk about another matter.
