Certainly, integrating the Matrix into the Heart of Machinery not only provided Li Yao with the troops he needed.
Among them were other Puppet Beasts and War Machines, such as the addition of Rune Mechanical Beasts to the usual Mechanical Beasts, which were Puppet Beasts endowed with runes and had certain synergistic effects.
For instance, Rune Mechanical Birds could combine multiple Mechanical Birds via the Rune Array into a much larger and more powerful monster, though the cost was too high, and the effectiveness of the first-order troops they produced was quite limited, a price Li Yao was unwilling to pay.
There was also the Rune Cannon, which consumed magical materials to fire Magic Bullets from the Magic Canon. It seemed promising but was practically not very useful due to its high consumption, susceptibility to malfunctions, and slow firing rate. What was intolerable was the pricey consumption of magical materials, which made it an uneconomical choice.
