Preparations for the war lasted about half a year.
Half a year later, Grella-13A.
Grella-13A was a very beautiful habitable planet, with roughly half its surface covered by oceans. Its volume was 90% that of Grella-13.
The planet was home to a vast number of lifeforms. More than half were Mechs, while the remaining portion—around 700 billion—were carbon-based intelligent lifeforms.
Aside from its smaller ocean area, Grella-13A's surface scenery was not much different from Grella-13's. The biggest differences were its fewer Space Tunnels and its slightly inferior technology.
The planet continued operating as usual, until today, when a tremendous change began!
In the Mech Imperial City of the Northern Hemisphere, a deafening boom suddenly rang out from the sky. The ground shook in response, and then the Space Tunnel, which had been closed for half a year, opened without warning!
A massive grayish-brown tower then flew out of the tunnel entrance.
Countless runes covered the tower's surface, linking together a huge number of electronic components. At the same time, its size expanded hundreds of times out of thin air!
This was the Data Interference Tower Su Yu had built under Sheng Ge's guidance.
The instant the tower appeared, its body plunged straight down into Grella-13A's soil.
At the same time, powerful interference signals were released from within the tower. The signals radiated outward at light speed and soon blanketed the entire planet.
The planet's Mechs were caught completely off guard and were immediately disrupted by the signals.
Those farther away fared relatively well.
Those closer to it, especially all Mechs within 300 kilometers of the Data Interference Tower, were almost entirely forced offline. 99.99% suffered black screens and crashed outright. Only the top one ten-thousandth of Mechs could barely resist.
Even so, their resistance was extremely difficult. Large portions of
