Global Tower Defense Strategy [End Times]

[I really have no inspiration, so I may not write the article, or I may change the settings later. If you mind, please cancel the collection (bow)] On the Spring Festival day, Si Nian witnessed an unknown object from the universe falling from the sky into the Forbidden City. Soon, the Forbidden City was sealed and troops were stationed. Scientists in many fields studied it and named it the origin of the universe. The whole world is paying attention, but they don't know that the crisis has quietly begun and the countdown to disaster is beginning. Three months later, alien civilization invaded the earth in order to seize the origin, blood stained the streets, and countless buildings were destroyed... The end of the world is coming, the origin of the universe is activated, silvery-white light sweeps across the world, a virtual channel is built in the sky, and alien civilizations are temporarily excluded. Human beings also undergo special changes under the influence of light. [Time is a hair ball, rolling around and developing infinitely; time will pass, but it will never disappear, it is everywhere; you should be proud of having the ability of time~] Si Nian opened the panel and looked at the name of his own power - [All time knows] Omniscient, omnipotent, omniscient and omnipotent. He seems to... Really should be proud of himself. Only by keeping the origin of the universe can we protect the earth, and by maintaining channels can we prevent alien invasion. Since then, a global tower defense battle has officially begun! Si Nian: Please call me the Commander-in-Chief of Tower Defense Strategies. Intention: Never admit defeat even in the end
