# Chapter 7: World Source 5%
Price: 1 Soul Coin, can only be purchased 10 times.
...
Seeing the rewards after killing the Black King, Su Xiao let out a long breath. He had finally found the third piece of the Black King Set, which was [Soul: King's Reincarnation].
Su Xiao didn't immediately use Soul Coins to exchange for rewards. He took a clay pot from his storage space. This item was called [Soul Coin Pot], a reward obtained from the Moon Woman. Opening it would yield 10 to 25 Soul Coins.
Obviously, using the [Soul Coin Pot] now was far more profitable than using it to improve the comprehensive evaluation. If he got 25 Soul Coins, that would be equivalent to increasing the reward for killing the Black King by an additional quarter.
Currently, Su Xiao had 105 Soul Coins. [Soul: King's Reincarnation] had to be exchanged. Legendary Set effects were even stronger than Epic equipment.
The remaining 35 Soul Coins obviously couldn't be exchanged for anything good. If he could get 20 Soul Coins from the [Soul Coin Pot], then [Black King Sword] would be within reach. If he got 23, then [Dark King's Blood] would be his.
As for [Melee Grandmaster Scroll], unless he gave up on [Soul: King's Reincarnation], there was no way to obtain this item.
Melee Grandmaster was very powerful, capable of elevating five Master-level abilities to Grandmaster level, but the growth cycle was too long. So long that Su Xiao might die in some world during the growth process.
This wasn't an ability that could be cultivated from the total gains of just a few worlds. Even if he really did elevate all five basic melee abilities to Grandmaster level, then what? The cost of simultaneously elevating five Grandmaster-level abilities was unimaginable. It would indeed be strong in the late game, but during the growth period, Su Xiao would be so poor he couldn't even upgrade Dragon-Slaying Flash, let alone other abilities.
Unless he had the resources of a Void faction or an entire Primordial World supporting him, it was simply impossible.
Su Xiao activated the Lucky King state and chose to open the [Soul Coin Pot]. The clay pot shattered in his hands, and crystalline translucent coins scattered.
[You have obtained 21 Soul Coins.]
Not the best outcome, but not the worst either. Su Xiao's Soul Coins reached 126.
[You have obtained 'Soul: King's Reincarnation', consuming 70 Soul Coins.]
[You have obtained 'Black King Sword', consuming 55 Soul Coins.]
[You have obtained World Source 5%.]
...
Just as Su Xiao finished the exchange, a few gravel stones fell from the ceiling. After losing the support of some kind of energy, the Birth Hall was about to collapse.
Su Xiao dragged the half-dead Amu with one hand and the old divine stick's corpse with the other as he walked out of the hall.
Over ten minutes later.
In front of a pile of rubble, Su Xiao inserted a sawtooth blade into the grave mound. A tattered long leather coat was tied to the blade's handle, fluttering in the wind.
"Farewell, Ken, Rahan."
Su Xiao shifted his gaze to a hunched old woman. This was Queen Reis. Su Xiao had seen her once before on the outskirts of Dead Silence City.
"Has he... left?"
Queen Reis spoke, her voice hoarse. She was asking about the Black King's fate.
"He's dead. I killed him with my own hands."
"Is that so... You sent him off. Thank you."
Queen Reis walked toward the Birth Hall, completely unconcerned that this hall was collapsing.
Boom, boom...
Massive stones crashed down from the ceiling, dust rising. Queen Reis looked at the Black King, who was kneeling on one knee inside the hall. She revealed a smile.
"My lord, I've come to accompany you."
Queen Reis stood before the Black King. Several large stones crashed behind her, blocking Su Xiao and the others' view.
A beauty's prime had faded; a king had returned to eternal silence.
Boom!
The Birth Hall completely collapsed, becoming a pile of ruins. A notification from Reincarnation Paradise appeared.
[Hidden Quest: Birth of Silence has been completed.]
[You have obtained an Epic Rank Optional Chest.]
...
The hidden quest was complete. As long as Su Xiao chose to complete the third ring of the main quest, he could return to Reincarnation Paradise. However, before that, he still had a few things to do.
Given Su Xiao's current injuries, he naturally couldn't continue exploring Dead Silence City. But before leaving, he needed to upgrade Blood Beast three times and activate the Black King Set. He also hadn't had time to examine the newly obtained [Black King Sword].
