External Soul Bone--Thunder God Whip!

A two-thousand-year-level Thunder Hell Vine Soul Ring!

Tang Yin sat cross-legged without a moment's hesitation. His Blue Silver Emperor martial soul manifested automatically, and the purple Soul Ring seemed to be drawn by a tether, slowly descending toward the top of his head.

The instant the Soul Ring settled around his body, "BOOM!"

It felt as if ten thousand thunderbolts had detonated within him simultaneously. The incredibly violent thunder-attribute energy and life force surged into his meridians like a burst dam.

Tang Yin's brows locked tight, his body trembling involuntarily. Xiao Wu watched from the side, deeply worried, her hands gripping the corners of her clothes tightly.

Time ticked away bit by bit.

The aura around Tang Yin fluctuated, at times as violent as thunder, at others as faint as a thread, but as time passed, it gradually smoothed out.

Before sunset.

The soul power overflowing from Tang Yin's body suddenly retracted, finally sinking completely into his core.

He slowly opened his eyes, a sharp flash of purple electricity seemingly flickering within his pupils before vanishing.

"Crack! Crack!"

Tang Yin stretched his limbs, and a deep purple Soul Ring rose steadily from beneath his feet, reflecting the brilliance of the two yellow Soul Rings that preceded it.

Xiao Wu, who had been guarding Tang Yin while meditating with her eyes closed, felt the disturbance and quietly opened her sparkling eyes.

When she saw Tang Yin with his three Soul Rings—two yellow and one purple—her eyes lit up. "Tang Yin, you actually succeeded!"

Tang Yin heard this, looked back, and smiled. "I am now a level thirty-two Tool Soul Elder!"

Xiao Wu gave Tang Yin a cute roll of her eyes, placed her hands on her hips, and huffed, "Don't get cocky. I'll be able to break through to level thirty soon, too!"

The commotion here also caught the attention of Lei Wuya. Seeing that Tang Yin had successfully broken through to become a Soul Elder, he let out a long sigh of relief.

"Dean, thank you." Tang Yin placed one hand over his chest and bowed in salute.

"No need for formalities. You are the most outstanding and talented soul master I have ever seen. Although your martial soul is only Blue Silver Grass, you must continue to work hard. Perhaps you can become the first-ever Titled Douluo whose martial soul is Blue Silver Grass!" Lei Wuya laughed and patted Tang Yin on the shoulder.

Tang Yin smiled. "I'll take your word for it; I will work hard."

Lei Wuya nodded with a smile. "I won't say anything more. Let's head back. We'll rest in the small town for the night and set off for the academy tomorrow."

"Understood!" Tang Yin nodded.

As they left the valley, Xiao Wu subconsciously glanced back at the Star Dou Forest behind them.

The three of them traveled safely without incident.

Perhaps it was because their stay in the Star Dou Forest had been short.

Or perhaps it was because of the distance.

Tang Yin had been worried the entire way that the Titan Giant Ape would come looking for Xiao Wu, but fortunately, it did not appear.

Inside the tavern in the small town.

Tang Yin pulled Xiao Wu into their room and locked the door behind him.

"Tang Yin, why are you being so mysterious?"

Xiao Wu's sparkling eyes blinked, and she subconsciously pursed her thin lips.

"Xiao Wu, I'm going to show you a great treasure!" Tang Yin looked back and smiled.

"A great treasure?" Xiao Wu was stunned.

The next second, Tang Yin began to take off his clothes—first his outer coat, then his inner layer, until he was down to his undershirt.

"Ah! Why are you suddenly taking your clothes off!"

Xiao Wu's eyes widened in shock, staring unblinkingly at Tang Yin's upper body.

Tang Yin raised his right arm and held it out in front of Xiao Wu. "Look! When I absorbed the Thunder Hell Vine, it seems I obtained an incredible treasure!"

"What treasure? I don't understand!" Xiao Wu's willow brows furrowed slightly as she reached out to poke Tang Yin's right arm.

Unlike before, Tang Yin's right arm was now covered in golden thunder patterns, much like the golden markings on the Thunder Hell Vine.

Tang Yin closed his eyes slightly and slowly channeled his soul power into his right arm. The golden patterns suddenly lit up and began to converge toward his palm.

Xiao Wu's mouth fell open in surprise. "This, this, this... how did this happen?"

A vine whip covered in golden thunder patterns gradually appeared in Tang Yin's right palm. It was very similar to the main trunk of the Thunder Hell Vine, and arcs of electricity crackled across its surface from time to time.

"CRACK!"

Tang Yin flicked the Thunder Whip, and the sound of thunder echoed through the room as sparks flew in all directions.

"Ugh!"

Xiao Wu let out a cry of surprise, startled by Tang Yin's sudden action.

Seeing this, Tang Yin scratched his head in embarrassment.

Xiao Wu, however, examined the Thunder Whip in Tang Yin's hand at close range with eyes full of curiosity.

"Is this your soul skill?"

"That's not right either!"

"You didn't even release your Martial Soul or Soul Ring!"

Tang Yin wore a thoughtful expression and mused, "Based on my guess, this should be a type of External Soul Bone. I can sense that this thunder whip is a part of my body. When I summon it, my attack power and speed both increase by fifty percent; this is an effect only a soul bone can provide."

"External Soul Bone? What is that?" Xiao Wu asked, somewhat surprised.

"An External Soul Bone is a type of soul bone outside of the six main human soul bones, and it can continuously evolve along with the soul master's own strength," Tang Yin explained.

Xiao Wu exclaimed in surprise, "In that case, the value of this thunder whip is extremely high!"

Tang Yin laughed, "The most important thing is that the power of this thunder whip itself seems quite immense, and it can merge with my body. It's very convenient to carry, and it won't make others think it's a soul bone, nor will it give them any thoughts of 'killing to seize the treasure'."

Xiao Wu pondered, "Hearing you put it that way, the value of this thunder whip is even higher."

Tang Yin smiled and nodded, examining the thunder whip as he said, "I call this thunder whip the Thunder God Whip."

"Xiao Wu, regarding the Purgatory Thunder Whip, you must never speak of it to outsiders," Tang Yin cautioned Xiao Wu after putting the Thunder God Whip away.

"Don't worry, I will keep my lips sealed!" A cute smile appeared on Xiao Wu's pretty face, and she felt exceptionally happy.

"Oh! Right, what is your third soul skill?" Xiao Wu asked curiously.

"Forest Purgatory Thunder Prison. It's a large-scale offensive soul skill that can't be unleashed here. Once we return to Suotuo City, we'll go to the Spirit Arena and I'll show it to you," Tang Yin laughed.

"Okay!" Xiao Wu nodded happily.

"It's getting late, I'm going back to sleep." Tang Yin quickly put on his clothes, his sleeve perfectly covering the golden thunder pattern on his right arm.

Even if it were exposed, others would only assume it was a tattoo and would not suspect it to be an External Soul Bone.

"Thunder God Whip... it really is quite a treasure. It is said that this Thunder Hell Vine truly possesses the bloodline of the Thunder God, though I don't know if it's true or false," Xiao Wu muttered.

The next morning, Tang Yin, Xiao Wu, and Lei Wuya set off after breakfast to return to the Suotuo Intermediate Soul Master Academy.

At the same time.

Martial Soul City.

Martial Soul Academy.

Inside the dormitory, Tang San... or perhaps he should be called Yue San, or Ju San now.

"Hum!"

Waves of soul power continuously radiated from Tang San's body, gradually intensifying.

The next second.

Tang San suddenly opened his eyes, the corners of his mouth curling upward: "I've broken through!"
