Robin Burton is a young man who grow with everything anyone can hope for, immense talent for cultivation, sharp mind, a wealthy family that will stop at nothing to protect and nurture him. He had everything except the willingness to take them. "Why would I take the same route as my ancestors ? why should I become stronger? to beat this and compete with that..?! THAT IS NOT WHAT I WAS BORN FOR!!" Robin didn't want to compete with young masters, so he made an army and started invading planets.
Before the war, Caesar had undergone only six sessions to modify his foundation to be compatible with new parts of the death law that was added to his heavenly law cultivation technique, and according to Rubin's initial estimates, he would need 14 additional sessions.
And if he managed to compress a few sessions of them to be every 3 weeks instead of every month, this means that he would need a year to complete the adjustments to the entirety of Caesar's foundations
And now, in the same year, he has to collect nearly 30 million gold coins worth of resources and energy stones…
That is a lot!!
Only a Royal Family with thousands of years of accumulation could confidently say that they can spend this much money within one year, yet even they would definitely not use this much gold if not to stop some kingdom's crippling issue!
