Neji typically acts after careful planning, and this time was no different. The "grand plan to make money gambling" first required a solution for sensing the number of dice inside the dice cup. This was already covered by his Byakugan. Next, he needed to transmit the sensed numbers, then have someone bet, and finally, leave safely after winning.
To transmit information, Neji thought of radio communication. The ninja world was a world with peculiar technological development, possessing products like televisions and radios, yet they weren't widespread. Radio communication had also been invented. Neji found a rather large electronics retailer and successfully purchased a set of radio communication equipment. The signal transmitting device was large, which was fine, but the receiving device, which looked like a helmet, definitely wouldn't meet his requirements. Taking that into a casino, even a fool would know something was wrong.
Therefore, Neji used his Byakugan combined with knowledge from his past life to heavily modify the helmet. He removed unnecessary components, even discarding the signal translator. Ultimately, he transformed it into a wristband. The wristband's function was very simple: it would emit a weak electrical current upon receiving a signal. A stronger signal would result in a slightly stronger current, and a weaker signal would produce a weaker current. If not for Neji's powerful sensory abilities, even a typical Jonin would have difficulty detecting such a faint current, making its concealment extremely effective.
With the transmitting and receiving devices ready, the next problem was who would do the gambling. Neji himself going was out of the question. Entrusting it to someone else, Neji wasn't entirely at ease either. Using a Shadow Clone with a Transformation Jutsu to gamble was feasible. He recalled how Tsunade could use the Transformation Jutsu multiple times to continue gambling to evade her gambling debts.
So, the only remaining issue was who to transform into. Choosing a target was time-consuming but necessary. Thus, Neji created five Shadow Clones, tasked with gathering information on long-term gamblers in the casino who lost more than they won, preferably those with minimal connections.
It took a total of six days to identify six suitable targets. After organizing the information on these six individuals, Neji began his operation. He selected one as his target for the day. This candidate was named Miki, a bachelor who lived alone on the outskirts of the village, had few friends or relatives, loved to gamble, and would rush to the gambling dens whenever he had money, usually losing. He was a quite suitable candidate.
As evening approached, Neji tampered with Miki's food, incapacitating him with a drug so he would fall asleep. Neji then had a Shadow Clone transform into Miki's appearance and leave Miki's residence. The clone headed to a larger gambling house that Miki didn't frequent often. Everything went smoothly until he exchanged his chips. Neji exchanged for 500,000 Ryo in chips. He didn't rush to cheat but started gambling normally. The game was simple: shaking dice and guessing high or low. Neji relied on luck and played for about an hour. Surprisingly, his luck was good, and he won around 200,000 Ryo. Neji feigned getting carried away and began increasing his bets, causing his funds to fluctuate significantly. At this point, his main body, standing a kilometer away, began to focus intently on the situation inside and transmitted the dice results via radio to the clone.
The clone didn't make a sound. While increasing his bets, he also controlled the win/loss ratio to appear as if he was still having decent luck, and he quietly pocketed some of the larger chips.
Another hour passed. The casino was bustling with noise. Neji calculated that he had won about four to five million Ryo. He quietly exchanged his chips and left the gambling house.
Neji followed his original route back to Miki's residence. Indeed, two tails were following him, but after confirming that Miki showed no abnormalities, they left. No murder or robbery occurred. Four to five million Ryo was roughly equivalent to one to two million in purchasing power on Earth. It wasn't an amount so large that the gambling house would risk the Konoha authorities by doing anything outrageous.
Watching the two tails leave, Neji deactivated his contingency. His main body went to Miki's house and cast a genjutsu on the sleeping Miki, making him firmly believe that he had gone gambling the previous night and won three to four hundred thousand Ryo, and that he wouldn't gamble again for a while. Leaving three to four hundred thousand Ryo with Miki, Neji returned to his residence.
Counting his earnings for the night, excluding the principal, he had nearly four million Ryo in profit, almost half of his net worth. After summarizing the night's experience and some precautions, Neji practiced briefly before sleeping.
Using the same pattern, Neji conducted five more operations. To reduce the risk of detection, Neji only won around two million Ryo each time and targeted different gambling houses, not exploiting the same one repeatedly. Therefore, all five operations went smoothly and did not arouse significant suspicion.
In total, his six ventures yielded over fourteen million Ryo. Combined with his remaining four million Ryo, he now had over eighteen million Ryo, alleviating any immediate financial concerns. However, finding a long-term source of income was now on his agenda, as gambling was not a sustainable plan.
