"Ji Wuchang, the elixir has been prepared, you can take it now!"

"However, although this elixir can help you open the Star Veins, it won't be enough for you to subdue a Star-related Strange Fire!"

"True Strange Fires are extremely terrifying. They are born from devouring spiritual essences of heaven and earth, and they contain immense energy within them!"

"Not to mention your current cultivation level, even a Supreme Realm expert must tread carefully when facing a Strange Fire."

"Many powerful Strange Fires are so dangerous that even Supreme Realm experts dare not touch them, or they risk falling!"

"Among the major powers in the world today, there is one called the Fire Domain. Their sect leader is a Strange Fire that has taken human form, and he is incredibly fearsome!"

"If you truly wish to subdue a Strange Fire, I suggest you seek something called the Ten Thousand Year Cold Marrow!"

"This substance contains its own internal space and is extremely cold. Even a Strange Fire cannot melt it."

"If you can obtain it, you can trap the Strange Fire inside and continuously absorb its energy!"

"By gradually weakening the Strange Fire's power, you can eventually subdue it completely."

Ji Yaoyao's words echoed in Ji Wuchang's ears, instantly invigorating him.

However, Ji Wuchang had never even heard of the Ten Thousand Year Cold Marrow. Just from the name alone, he could tell it was something extraordinary!

"Yaoyao, what exactly is the Ten Thousand Year Cold Marrow? Why have I never heard of it before?" Ji Wuchang asked, determined to understand this mysterious substance.

As soon as he finished speaking, Ji Yaoyao's voice rang in his ears again.

"The Ten Thousand Year Cold Marrow is extremely rare. Even I have only seen it in someone else's possession before."

"I can only tell you that it originates from a place of extreme cold. It's impossible for you to find it on your own; you can only purchase it at a high price from others."

"Whether or not you can obtain it depends entirely on your own abilities!"

Hearing this, Ji Wuchang couldn't help but sigh. He wondered if Zhou Haotian had sent him here for some hidden reason.

It wasn't that Ji Wuchang was being paranoid—it was simply the reality of the situation!

After thinking for a while, he decided to put it out of his mind. He sat down cross-legged and swallowed the Seven Star Elixir that Ji Yaoyao had prepared for him.

As the elixir entered his stomach, a unique energy erupted, filling his dantian.

This energy was incredibly peculiar—it didn't have a fixed attribute.

Cold, heat, and the five elemental powers of metal, wood, water, fire, and earth were all contained within it.

After a brief inspection, Ji Wuchang realized that this energy was a fusion of at least dozens of different elemental forces.

"Could this have been refined from Star Power?" Ji Wuchang immediately thought to himself.

But just as he was pondering this, the energy erupted violently and surged throughout his body.

He didn't have time to process it and quickly activated the Purple Qi Burning Heaven Technique to refine the energy.

This was both an instinctive reaction and a standard method of self-protection!

His Purple Mansion trembled violently, and the five elemental forces began to circulate on their own. A Tai Chi diagram appeared and began to spin rapidly.

At the same time, a mysterious mark appeared in Ji Wuchang's soul sea, emitting a purple light.

Before Ji Wuchang could even gather this energy to open his Star Veins, it was devoured almost instantly.

This startled him—after all, Zhou Guangrong had given him the elixir, and he would surely ask about it later.

Ji Wuchang wanted to stop it, but he couldn't. The massive energy had split into several streams and was devoured almost instantly!

He could only watch helplessly. Half an incense stick's time later, the effects of the Seven Star Elixir faded, and Ji Wuchang stood up.

He had no idea how he would explain this to Zhou Guangrong!

He had taken an entire elixir, but the "bandits" within his body had stolen all of it. He hadn't even managed to break through a single minor cultivation stage.

Ji Wuchang was speechless. He could only hope that these "bandits" wouldn't disappoint him in the future!

"System, use cultivation to practice the 'Grinding Thunderfire' technique!"

[Ding! Master, in the tenth year of your cultivation, you have officially begun mastering the 'Grinding Thunderfire' technique!]

[Master, in the twenty-second year of your cultivation, the 'Grinding Thunderfire' technique has reached the Minor Achievement stage. The Thunder Dragon within your body has mutated!]

[Master, in the thirty-fifth year of your cultivation, the 'Grinding Thunderfire' technique has reached the Major Achievement stage!]

[Master, in the forty-ninth year of your cultivation, the 'Grinding Thunderfire' technique has reached the Perfection stage! You have comprehended the Dao of Thunderfire Conversion!]

[You have further comprehended the Profound Meaning of Thunder. The Thunder Dragon within your body has been rewarded with Origin Power and has grown several times in size!]

The system's voice rang out, and Ji Wuchang was almost stunned. He couldn't believe his ears—he had actually gained the Origin Power of Thunder!

Overjoyed, he was suddenly overwhelmed by a flood of terrifying insights that threatened to drown him.

The sheer volume of insights was too much. Ji Wuchang grunted and quickly sat down cross-legged to absorb them.

In his soul sea, a massive grinding wheel occupied half of the space.

One half of the wheel crackled with lightning, as if the Thunder God had descended; the other half spewed flames, ready to incinerate everything.

His soul felt excruciating pain.

At the same time, the atmosphere in his courtyard became extremely eerie. Wisps of lightning energy emerged from the ground and rushed toward Ji Wuchang.

This lightning energy was different from normal lightning—it was infused with various rules of the Dao.

This wasn't ordinary lightning energy—it was the power of Thunder Origin!
