The Mechanical Core has many names: Heart of Machinery, Titan's Heart, Heart of Creation. Rumor has it that if you continually upgrade the Mechanical Core, it will become a true Titan's heart, of course, this is just a rumor and has not been confirmed, but its rarity and preciousness are beyond doubt.
However, no one has been able to upgrade it as a whole, not even Li Yao, so he could only select one of its functions to enhance a specific aspect of its quality.
This is a versatile treasure, but in Li Yao's view, whether it's improving the quality of mechanical life or increasing the grade of engineering, both are highly uneconomical actions.
