I Don’t Have Money To Practice Martial Arts!

In his previous life, Shen Lian was a genius fund trader on Wall Street. He worked his way up from the bottom step by step, but when he was most successful, he died due to long-term fatigue.
Traveling through CR-7 Edge Star, Shen Lian became a hunter in Lijia Town who was on the verge of power outage.
In this crazy world, practicing means consuming electricity, and losing power means death.
Whether it is the lowest mortal realm or the supreme martial god realm, there are no exceptions. If there is no money to buy nutrient solution, there will be no bioelectric energy, and the body will be completely scrapped like a dried up battery.
In order to save his life, he squatted in the mountains for two days, killed the razor wolf with one shot, and repaired several wolf cubs.
Back in town, I was only willing to change to the cheapest "Leibi" nutrient solution, which barely maintained the battery for three days.
In the examination room of the provincial capital, the rich second generation Zhao Tianyu was riding in a gold-encrusted mecha and bombing the streets, laughing at him as a refugee who couldn't even repair a mecha.
Shen Lian remained silent. He barely passed the physical fitness test, but he shot ten rounds at the shooting range and amazed everyone.
However, the gene lock test actually sucked up the school’s million-level energy core. The principal was furious and offered him a contract: a student loan of 3 million federal dollars, with an annual interest rate of 15%, and if he couldn't pay it off, he would go to the front line to be cannon fodder.
Shen Lian signed.
He was carrying a huge debt of 3 million and guarded the rusty and scrapped mecha "No. 07".
Since practicing means burning money, he treats martial arts as a business.
Digging "Worry-Free Grass", repairing garbage mechas, and calculating every penny of profit and loss in the toilet.
In this life, he will not only become a god of war, but also live forever!
