When he learned that the Sword World was about to open, Jian Wushuang immediately returned to the Green Fire Palace without hesitation.
After all, it only opened every hundred thousand years. If he missed the opportunity this time, he had to wait another hundred thousand years to enter it again.
On the way back to the Green Fire Palace, he received a message from Celestial Master Yi and Celestial Master Meng Long.
Dan Xin was indeed making fun of them.
Quite a few Celestial Masters from the two camps followed his instructions to mine Black Iron on that battlefield recklessly. Within a few days, someone had gathered five hundred thousand kilograms of Black Iron.
Nonetheless, when they handed the Black Iron to Dan Xin, he said whoever had cultivated for more than five hundred thousand years were not qualified to become the master of the Dan Xin Palace. Many Celestial Masters from the two camps had been outraged by this.
