Mu Cheng needed to slay the Evil Lice. She had extremely strict requirements for the weight and volume of her sword. Otherwise, she couldn't achieve precision, let alone wield it with ease. In other words, Mu Cheng wanted to forge a sword using the same amount of material as a Heaven-piercing Halberd, yet keep its weight at the level of a dagger. It was simply a fantasy.
Only the Divine Land Research Institute could even attempt such a feat. After all, it was the world's top research institution; other nations wouldn't even dare to imagine it.
However, even if the forging was successful, the sword's durability remained a major issue. Adding more alloys could increase its hardness, but its density would ultimately be unstable. Forget about using it in the Wet Realm; even on Earth, it wouldn't last very long. It was a complete waste of manpower and resources.
"Thank you!" Mu Cheng nodded to the staff member.
