Heading to the Ice and Fire Yin-Yang Well

The two walked one after the other, heading deeper into the Sunset Forest.

Dugu Bo was clearly very familiar with the routes in this vicinity. He wove through the dense forest, at times bypassing a swamp, at others squeezing through a narrow rock crevice. After winding around for about an hour, the surrounding vegetation began to change significantly.

The temperature in the air became abnormal—one moment it was as hot as a steamer, the next as cold as midwinter. Two diametrically opposed auras intertwined, forming a unique energy field.

The surrounding plants also became increasingly peculiar. Some were entirely crimson, their leaves like burning flames; others were icy blue, their surfaces coated in fine frost; and some displayed a bizarre, half-red, half-blue hue, as if enduring the baptism of both ice and fire simultaneously.

"We're here." Dugu Bo stopped and pushed aside a cluster of dense shrubs in front of him.

Yu Tianlong stepped forward, and the sight before him made him hold his breath.

It was a basin hidden within a valley, surrounded by mountains on all sides with steep cliffs, as if split open by some great force to form an isolated world. In the very center of the basin lay two springs, one on the left and one on the right, residing side by side.

The spring on the left presented a deep, crimson red. The surface bubbled incessantly, steaming with scorching vapor; even from dozens of meters away, one could feel the heat wave rushing toward them.

The spring on the right was pure, icy blue. The surface was as calm as a mirror, emitting a bone-chilling cold that caused thick frost to form on the surrounding rocks.

One hot, one cold; one red, one blue. They were clearly demarcated, neither encroaching upon the other.

Surrounding the two springs grew dense clusters of plants. Some were as lustrous as jade, some as fiery as embers, some entirely transparent like crystal, and others a bizarre, purplish-black.

They came in all shapes and sizes—some like lingzhi, some like orchids, some like vines, and others like fruits. Each stalk radiated a rich medicinal fragrance and fluctuations of Soul Power.

"The Ice and Fire Yin-Yang Well..." Yu Tianlong murmured, his voice filled with irrepressible excitement.

This was it!

Ever since he had transmigrated to the Douluo Continent, the opportunity he had been searching for was right before his eyes!

With the immortal herbs here, his strength would undergo a qualitative leap! His two Luo Sanpao would also be able to complete a further evolution with the help of the extreme ice and fire energy here!

"You recognize these plants?" Dugu Bo asked curiously, seeing the look of excitement on his face.

"I recognize some of them." Yu Tianlong took a deep breath to suppress the agitation in his heart. He turned to look at Dugu Bo, his eyes gleaming.

"Senior Dugu, every one of these plants is an immortal-grade herb rarely seen in the outside world. If used properly, they can significantly increase a Soul Master's cultivation, reshape their physique, and even trigger a Martial Soul Evolution!"

"Immortal-grade herbs?" Dugu Bo's eyes lit up. "They can increase cultivation? Then why didn't you say so earlier! I've been here several times, but I never dared to touch them, fearing they were poisonous."

"Your caution is justified, Senior," Yu Tianlong laughed. "Although these immortal herbs have heaven-defying effects, their medicinal properties are extremely overbearing. Consuming them blindly is not only useless but harmful. One must choose the right herb based on their individual physique and Martial Soul attributes, and consume it using the correct method to achieve the maximum effect."

He walked to the side of the crimson spring and crouched down, looking at a plant by the water that was entirely red and shaped like coral. A glint of light flashed in his eyes.

"Take this 'Infernal Delicate Apricot,' for example. It contains extreme fire-attribute energy. If a fire-attribute Soul Master consumes it, it can significantly increase their fire-attribute affinity, and it could even evolve their Martial Soul into a top-tier fire-attribute one."

He then walked to the icy blue spring and pointed to a plant that was entirely icy blue and shaped like a lotus. "That 'Octagonal Mysterious Ice Grass' contains extreme ice-attribute energy and is suitable for ice-attribute Soul Masters."

He stood up and looked around, his eyes full of excitement. "And every immortal herb here has its own unique effect. If paired correctly, they can even make a person shed their mortal body and exchange their bones!"

Dugu Bo stood to the side, listening to Yu Tianlong rattle off a string of names and effects. The expression on his face shifted from initial curiosity to shock, and finally, to complete numbness.

"Wait, wait, wait..." Dugu Bo couldn't help but interrupt him, pointing at the plants on the ground that he didn't recognize at all.

"How do you know all of these? I've flipped through many ancient texts and couldn't find a trace of these things. You're an eight-year-old kid; how do you know more than I do?"

Yu Tianlong had long since prepared his excuse, answering without changing his expression or skipping a beat.

"I once read an ancient book in my family's Library Pavilion that specifically recorded various rare treasures. It just so happened to have pictures and descriptions of these immortal herbs. I was just flipping through it at the time; I didn't expect it to come in handy today."

Dugu Bo looked at him with skepticism but didn't press the matter. After all, everyone had their own secrets, and he wasn't the type to get to the bottom of things.

He waved his hand and said generously, "Fine, fine. Since you recognize them, then leave the handling of these things to you. I don't recognize them anyway, so it's a waste to leave them here. Take whatever you want, don't stand on ceremony with me."

"Senior, how could I..." Yu Tianlong quickly declined. "You discovered this treasure land; by rights, all the immortal herbs here should belong to you. I am already satisfied to be able to share in your good fortune."

"None of that," Dugu Bo glared at him irritably.

"You saved my son, and you saved half my life. These things are just pretty-looking weeds to me, and I don't know how to use them. Instead of letting them rot in the dirt, it's better to let you put them to use. This is called making the best use of everything, understand?"

He paused, then added, "Besides, once you get stronger, you'll have a better chance when you go to take revenge on that old thing, Yu Yuanzhen. Don't forget to give him a couple of kicks for me when the time comes; consider that my repayment."

Hearing this, a warm current surged through Yu Tianlong's heart. He knew that although Dugu Bo spoke lightly, he was actually helping him in this way. He kept this sentiment in his heart.

"Since Senior is so generous, this junior will not decline." Yu Tianlong stopped refusing and turned to carefully select from the immortal herbs.

He first picked three herbs suitable for Dugu Bo.

The first was a flower that was entirely blood-red and shaped like velvet. The petals were covered in fine fuzz, emitting an eerie beauty.

The Blood Swan Kiss was not poisonous in itself, but it could amplify the effects of any poison it came into contact with a thousandfold. For a Soul Master like Dugu Bo, who was famous for his poisons, the value of this immortal herb was simply immeasurable.
