679 Grand Illusionary Legion!

The units inside the chests of the seven crystal suits emanated starry crimson brilliance that pierced into Li Yao eyes through the Grand Illusionary Land like countless rubies.

Cold sweat was popping up on his forehead.

If there were no Exos inside, such magical equipment was not a crystal suit, but a human-shaped beast puppet. They were also known as 'spiritual puppets'.

Spiritual puppets were once a piece of popular magical equipment. They were tireless and fearless, and they could fight in extremely harsh environments, which made them the perfect weapons for a war.

However, spiritual puppets were commanded by crystal processors. However advanced crystal processors were, they were dead objects after all and could only carry out orders rigidly despite their immense computational ability.

There were too many variables in a battlefield. Even the crystal processors with the best performance could not replace the brain of a human.
