It is precisely because the "underground arena" of Black Star City does not have any rules that every warring party will do their best to improve their strength before the battle, and use all available channels to collect each other's intelligence.

This combination of open and dark battles on and off the field actually constitutes a complete "underground competition...... Because the warring sides often have a large error in their estimation of each other's combat power, the battle on the field is often extremely fast, and it is likely that the victory or defeat will be clear within one or two moves......

And the losing side will naturally not end well...... It can be crippled or seriously injured, or directly killed.

In Black Star City, accidental death is really a normal thing.

And while the two-way game often ends with the death of one of the players, it is not the climax of a race......

Next, the winner will be challenged by the audience on the field!

That's right, everyone who participates in watching the underground competition can actually be counted as a "potential opponent" of the competitors.

At the beginning of a match, each player hands over a "Competitive Gold", and when a person wins the battle, he will receive all the Competitive Gold for himself and his opponent......

And when a spectator takes the initiative to become the "challenger" of the winner, he must also hand over a "competitive gold" and invest it in the total "competitive prize pool" in order to fight the winner......

Then, it is still a one-on-one duel, and the winner will receive all the competitive gold in the "competitive prize pool", and the loser will naturally be either dead or disabled.

After the second winner is decided, the remaining spectators can challenge the winner, but the second challenger will have to double the "competitive prize pool", and so on.

Each subsequent "challenger" needs to invest twice as much as the previous challenger...... This "underground competition" will not end until none of the spectators present can afford to compete or because the winner is too strong to face the competition.

The winner in the ring will receive all the cash in the current "competitive prize pool".

The rules are like this, they seem simple and straightforward, but in fact, there are many doorways in them.

For example, this rule is actually very disadvantageous for the two competitors who start the game, after all, there must be a defeat in the competition, if the difference in strength between the two is not huge, the winner of the two is estimated to have a lot of consumption or even hanging the lottery...... The next challenger will be on the pitch almost immediately, with little time to rest and recover, and even if he can beat the challenger again, there will be another ...... It can be said that if the starting competitor wants to win the final prize, he must have to deal with waves of wheel battles.

And the follow-up challengers are actually the "spectators" who watched the game before, the habits of the starting competitors in the battle process and the means of pressing the bottom of the box, can be regarded as completely exposed, and they will naturally be targeted accordingly, and for them, the "challenger" who is about to play is completely a mystery, and in the case of unequal information, even if they encounter an opponent whose hard power is not as good as their own, it is very easy to capsize in the gutter.

For the "challengers", although the latecomers have a great advantage, they are not harmless.

For example, since each challenger needs to invest twice as much money, if you are shy in your pocket, you won't even be able to afford it when you get to the back......

And the further the challenger enters, the lower the return ratio is.

For example, if the two competitors who start each invest 1 Star in Competitive Coins, there will be a total of 2 Star Coins in the competitive prize pool...... The first challenger raised 2 Stars, the second raised 4 Stars, the third 8 Stars, and the fourth 16 Stars...... Assuming that there are only four challengers in the tournament, the total amount of prize pool in the final tournament will be 32 Star Coins.

It's easy to calculate, assuming that the winner is one of the starting competitors, and that the net benefit they get is 31 stars, which is a full 32 times more money when they put in the cost of 1 star.

And if the final winner is the first challenger, then his assets are equivalent to 16 times more.

But if the fourth, or last, challenger wins, then his assets will only triple, that is, the principal is removed, and the net income is doubled.

Overall, it's a night, the lower the risk...... But the lower the revenue, the lower the game.

Of course, all of this analysis is based on the premise that you have enough money and enough strength to be eligible to participate...... If the opponent standing in the ring is too strong and you are not an opponent at all, then it is equivalent to saying...... In this underground competition, you will completely become a "spectator", and you will not get any benefits...... Keep in mind that tickets for spectators in the Underground Arena are expensive, and every "spectator" who doesn't take part in the challenge is actually losing money - but if you think that just watching a series of spectacular battles is worth the expensive ticket price, then you don't lose money.

After listening to the operation principle of the entire underground arena, Yan Xiuze was obviously very interested in this model, and in the afternoon, he asked the Fran brothers to lead the way, and the three of them went to the largest underground arena in the vicinity, where a competitive meeting would be held in the afternoon.

Although the tickets for two hundred star coins were indeed a bit frighteningly expensive, fortunately, Yan Xiuze had just robbed a district leader before, and he was not short of money, so he happily used an obsidian card to draw out six hundred star coins, and the three of them swaggered into the underground venue......

After entering the underground venue, Yan Xiuze quickly turned his head and looked around, and the overall layout of the entire space was automatically printed out in his mind......

The underground layout of this underground arena is somewhat similar to the ancient Roman Colosseum, the whole environment is like a "bowl" shape, the bowl is a ring seat along the edge, row after row, the field of vision is very broad, and the "bottom of the bowl" is a fast round flat ground, as a ring, surrounded by a high wall, the competitors in the ring, with such an environment, it is quite a bit of "trapped beast fight" meaning.

At the top of the bowl, the ceiling closest to the ground, there is a cylindrical pipe with no known function, and below the pipe is a huge transparent cube box suspended with steel cables, which is the core driving force of the entire underground competition - the competitive prize pool.

Whenever a challenger enters, the competitive gold is raised...... The corresponding amount of star coins will fall into the transparent cube in the pipe, and this process can be clearly seen by almost all the spectators, including the competitors - they also know in their hearts that only the last person standing in this ring will be eligible to receive the star coins in the cube.
