The legendary marrow cleansing

"Finally, my golden opportunity, what took you so long?" Dante exclaimed with excitement.

[Ding* Congratulations, Master! You have been bestowed with a newbie gift pack from the system] [Would you like to open it?] System declared with a dispassionate voice.

"Open," Dante stated.

With a burst of light, three items materialized on the system panel.

[Received a body forging elixir] [Received a skill selection card] [Received a character summon card] [The items have been stored in the system inventory]

While gazing at the screen, Dante inquired of the system, "System, what are the uses of these items? Please provide a comprehensive explanation." With eager anticipation, Dante awaited the system's response.

[Master, the body forging elixir is a potion that can be utilized by the master to sculpt his physique into the ideal form he desires] [The skill selection card can be employed to acquire a skill from a character the master desires within his own games] [And as for the character summon card, it can conjure a character from the master's game world to assist him in his endeavors. The summoned being cannot act against the master's wishes]

"Sweet," Dante exclaimed, excited at the sight of these items.

Firstly, he retrieved the Body Forging Elixir. It was a golden liquid stored in a glass vial, roughly the size of a tennis ball. It looked exquisite, twinkling like a gem with its golden hue. Dante admired it for a moment before slowly opening the cork and consuming it in a single gulp.

Gradually, his body began to heat up, and various changes took place. His lightly muscular physique became chiseled, his skin, once dull and rough, turned as soft as a baby's. His height, previously stagnant at 5'9, gradually increased to 6'3.

Following this, a substantial amount of black substance started oozing out of his pores, covering his entire body.

"Gross… What is this substance emanating from my body?" Dante exclaimed in disgust.

"Wait a minute… Is this the Legendary Marrow Cleansing mentioned in those wuxia novels?"

"System, explain what is happening to my body," Dante asked with visible excitement.

[Master, from birth, every living being is impacted by the mortal world. Impurities such as smoke, toxins from food/water, or chemicals enter the body through respiration, consumption, or contact. Due to these impurities being too small or stubborn, the body is unable to expel them. As time passes, they accumulate, reducing the life expectancy of mortals. But, Master, the elixir you consumed possesses the ability to continuously expel these impurities]

Dante felt solemn upon hearing the first part, but he was elated upon learning about the elixir's effects.
