With sufficient metal materials this time, Huang Tian once again controlled the Black Hole Space to continuously break down and reassemble the flying swords, metal materials, and Peak-grade Crystals, improving the quality of the Peak-grade Immortal Artifact flying swords.
Three months later.
Huang Tian had raised all those flying swords to the level of Mid-grade Divine Tools. By then, half the metal materials in the Black Hole Space had been consumed—a full fifty million tons—and five hundred thousand tons of Peak-grade Crystals had also been used to raise this batch of flying swords to Mid-grade Divine Tools.
His mastery and development of the Black Hole Space had risen to another level.
Huang Tian once again gathered all the guards and several Guardian Elders outside the immortal residence. With a wave of his right hand, he released all the Mid-grade Divine Tool flying swords except those belonging to Qian Renxue and the other three women, while concealing their divine tool aura to prevent energy fluctuations from leaking out.
Huang Tian said with a smile, "I gathered you here today because, after four months of work, I have finally upgraded your flying swords to Mid-grade Divine Tools. Go forward and claim one flying sword each. Remember to bind them as your masters this time, lest those high-level Mysterious Immortals outside steal them away."
"Thank you, Hall Master!" Everyone cupped their hands in salute and shouted.
"Alright, come claim your flying swords. Pick whichever you like. They are all identical in design, with only slight differences in color, and every one is a Mid-grade Divine Tool. One flying sword per person. Once you have it, return to your rooms, bind it as your master, and store it in your Dantian to nourish it." Huang Tian added another reminder, still not entirely at ease.
