The next day.

Chu Hao found the Northern Spirit Palace Master and took out the Yin and Yang Master Treasure Book.

The Northern Spirit Palace Master became immediately engrossed and couldn't pull himself away.

"Wonderful, truly wonderful." The Northern Spirit Palace Master patted his thigh, so excited he could hardly contain himself.

The Northern Spirit Palace Master could feel that he could identify some of his own shortcomings from this Yin and Yang Master Treasure Book, and if he corrected them, his strength could improve!

This is simply incredible; to know that the current power of the Northern Spirit Palace Master is one of the top levels in the Holy City, and it could still be corrected and improved!

It's estimated even the highest-level Yin-Yang Practitioners couldn't achieve this.

The Northern Spirit Palace Master was extremely excited, saying, "Where did you find this? This treasure book is simply the Yin Yang Ultimate Study! No, it's far more useful than any ultimate study; if it spreads, every Yin-Yang Practitioner could see a significant improvement!"

Chu Hao yawned, saying, "I stayed up late writing it last night."

"Ding... The host nonchalantly acted pretentiously, shocking the Northern Spirit Palace Master, gaining 6,000 Pretentiousness Points."

What the hell!

Are you kidding me?

Writing such a world-shaking book just by pulling an all-nighter, are you even letting me live?

The Northern Spirit Palace Master asked suspiciously, "Really?"

Chu Hao didn't answer, extending his hand and saying, "Where's my Five Elemental Spirit Controlling Technique?"

The Northern Spirit Palace Master took out a yellowed book and tossed it to Chu Hao.

Item: Incomplete Five Elemental Spirit Controlling Technique

Rarity: ★★★★ (Four Stars)

Ability: Harness Five Elemental Spirits (Only the remnants can control Gold, Wood, Fire)

"Ding... The Five Elemental Spirit Controlling Technique can be exchanged for seventy thousand Pretentiousness Points."

"Ding... Learning the Five Elemental Spirit Controlling Technique requires the expenditure of ten thousand Pretentiousness Points."

Chu Hao couldn't help but complain, "Palace Master, are you joking with me? Why is it an incomplete piece?"

The Northern Spirit Palace Master was a bit embarrassed, saying, "The complete Five Elemental Spirit Controlling Technique was scattered a hundred years ago. Having three element spirits is quite decent."

Chu Hao's mouth twitched, saying, "Isn't it inappropriate to cheat me like this? I put so much effort into helping Bei Ling Academy."

The Northern Spirit Palace Master was embarrassed, finally taking out another item, again a yellowed book, saying, "I didn't expect the Yin and Yang Master Treasure Book to be so valuable. I also give this Thunder Technique to you; it's the strongest Yin Yang Ultimate Study of Bei Ling Academy; whether you can learn it is up to you."

Chu Hao took it in hand.

"Ding... The Hum-Ha Thunder Technique can be exchanged for seventy thousand Pretentiousness Points."

"Ding... Learning the Hum-Ha Thunder Technique requires the expenditure of ten thousand Pretentiousness Points."

Chu Hao was finally comforted; the two combined are worth a total of 140,000 Pretentiousness Points, not a loss in this deal.

Chu Hao reviewed the two books and finally decided to exchange the Five Elemental Spirit Controlling Technique, though it was worth 100,000 Pretentiousness Points. It was mentioned that only when the Five Elemental Spirit Controlling Technique was complete could its true power be unleashed.

On the contrary, the two-word Thunder Technique was also strong; once the Hum-Ha two words are released, the power is immense.

"Exchange the Five Elemental Spirit Controlling Technique."

"Ding... The host exchanges the Five Elemental Spirit Controlling Technique, gaining seventy thousand Pretentiousness Points, remaining Pretentiousness Points are 80,000."

"Learn the Hum-Ha Thunder Technique."

"Ding... The host learns the Hum-Ha Thunder Technique, expending ten thousand points, remaining Pretentiousness Points are 70,000."

Item: Hum-Ha Thunder Technique.

Rarity: ★★★★★ (Five Stars)

Ability: Hum-Ha Two-Character Thunder Technique. "Hum" for long-range attack, "Ha" for melee attack, (Each use expends ten thousand Mana Points.)

Ability two: Hum-Ha Thunder General, expending two hundred thousand Mana Points to summon.

Brother Hao is invincible! Just waiting for someone clueless to come out for a fight.

Chu Hao targeted the Northern Spirit Palace Master, chuckling, "Palace Master, shall we have a duel?"

The old Palace Master was still immersed in the Yin and Yang Master Treasure Book. Hearing Chu Hao's words, he was taken aback, squinting with a smile, "Are you sure you want to duel with me?"

Chu Hao nodded; he really wanted to test this era's top Yin-Yang practitioners.

"Alright!" The old Palace Master said.

The two found an open area, attracting people from Bei Ling Academy who came running to watch the show.

"Chu Hao wants to duel the Palace Master?"

"My goodness, our Palace Master was one of the previous generation's Grand Scholars; Chu Hao sure has guts."

"This should be entertaining to watch; I bet Chu Hao will surely get beat up."

"I also bet he gets beat up."

Upon hearing this, Chu Hao was taken aback; this old man turned out to be so strong, being one of the previous generation's Grand Scholars, no wonder he could be the Palace Master.

The Northern Spirit Palace Master stood with his hands behind his back, looking kind and amiable, standing still and smiling faintly, saying, "Come on! Use your strongest technique; this old man would like to see the skills of this generation's Grand Scholar."

Chu Hao also wanted to test just how strong the strongest in this world was.

He quickly formed hand seals, and the Northern Spirit Palace Master originally had a smile on his face. But upon seeing the technique of Chu Hao's hand seals, he was instantly shocked, saying, "Wait... you!"

Chu Hao formed a seal with his right index finger, circling it around his mouth.

"Hum."

Suddenly, the air ahead exploded like thunder, a strong force surging towards the Northern Spirit Palace Master.

"Boom!"

The place where the Northern Spirit Palace Master stood erupted with a loud thunderous crash, and the area within a three-to-five-meter radius seemed to be struck by lightning, turning pitch black.

As the smoke cleared, the Northern Spirit Palace Master was covered in soot, his entire body blackened, his hair standing on end, severely singed by the thunder.

The students from Bei Ling Academy watched, dumbfounded.

The Northern Spirit Palace Master, furious, pointed at Chu Hao and said, "Is this the Hum-Ha Thunder Technique?"

Chu Hao, surprised, asked, "My goodness, are you unharmed?"

Indeed, despite the thunderous explosion just now, the Northern Spirit Palace Master was only singed black, making him look bedraggled but otherwise unharmed, which was truly unbelievable.

However, more than Chu Hao was shocked; the Northern Spirit Palace Master could be one hundred percent sure that the technique used was indeed the Hum-Ha Thunder Technique.

To know that Chu Hao had only just obtained the Hum-Ha Thunder Technique and learned it at a glance was just impossible, right?

This is not scientific.

The Northern Spirit Palace Master was astounded, asking again, "Is this the Hum-Ha Thunder Technique!"

Chu Hao laughed, "Whether it's the Hum-Ha Thunder Technique, doesn't your heart have any clue, Palace Master? I, Chu Hao, am a prodigy, and Bei Ling Academy's ultimate study is just that! There's really nothing I can't learn."

"Ding... The host acted pretentiously successfully, gaining 6,000 Pretentiousness Points."

The Northern Spirit Palace Master was on the verge of breaking down; learning the Hum-Ha Thunder Technique at a glance, even the most talented he had encountered couldn't compare to even a toe of Chu Hao.

The Northern Spirit Palace Master, exasperated, said, "This Palace Master would like to see what other methods you have."

The Northern Spirit Palace Master formed hand seals with both hands, exclaiming, "Spirit Control Technique, Wood Technique."

Suddenly, the ground beneath Chu Hao trembled, and from the earth veins below, several cylindrical large logs shot up like bullets from the ground.

Chu Hao was instantly launched into mid-air.

Chu Hao formed hand seals again, shouting, "Hum."

The "Hum" character Thunder Technique surged at the Northern Spirit Palace Master, but logs appeared in front of him, blocking the Thunder Technique. The logs also smoked, turning black as if struck by lightning.

Chu Hao landed on the ground, with the Northern Spirit Palace Master forming hand seals with both hands, saying, "Trapped Beast Formation."

To see that the previous logs emerging from the ground are only the setup for a formation?
