Zero.

The countdown disappears.

A three-dimensional rotating Rubik's cube-like thing appeared on the screen, and after spinning it several times, it stopped.

Song Ci glanced at this thing, it was like it was made up of many small boxes, and inside each box was a puzzle, consisting of ninety-nine eighty-one boxes, and when it came to the last box, it could be close to the final super box.

Whoever opens the Super Box the fastest is the first place.

In previous competitions, the prize for the first place was 100 bitcoins or more.

The previous questions are relatively simple, basically you can get them done in two or three minutes, and after the thirtieth box, the difficulty of the questions begins to increase.

Ordinary hackers will stay at thirty or forty levels, hackers with a slightly higher level can hit fifty or sixty levels, and few people can reach seventy levels.

The previous simple question Song Ci didn't take long, basically a question in about a minute, and when it reached the thirty level, the speed of solving the problem was a little slower, but it could also ensure that a question was solved in five minutes.

At the top left of the screen is a progress meter that shows the top 10 solution speeds.

So far she is in second place, and the first place is still the "King of Spades".

But judging by the schedule, she and the "King of Spades" are now in the forty-seventh box, but her speed is slightly slower than the "King of Spades" by more than ten seconds.

Song Ci frowned slightly, and no longer paid attention to the progress bar.

Sometimes paying too much attention to gains and losses is more likely to affect performance.

Song Ci put all his attention on solving the problem.

After entering the sixtieth box, two people in the top ten have already begun to stagnate. Only the top eight progress bars are still ahead.

After sixty levels, it is extremely difficult, and each question, even the fastest speed, takes twenty or thirty minutes.

Slowly, the eighth, seventh, and sixth places all stopped.

Until the seventy-third box, only Song Ci and the "King of Spades" were left among all the people who participated in the competition.

The two of them are almost up and down, and sometimes Song Ci's speed will exceed the "King of Spades", but the "King of Spades" will find a way to catch up.

Hackers all over the world seemed to be watching the game, and everyone was staring at the progress bar excitedly, watching Song Ci and the "King of Spades" fight.

In the past games, everyone watched the "K of spades" one-man show, basically to more than 70 levels, only the "K of spades" can continue to the front, and the result of the game is not suspenseful at all.

But this time, the game was extremely worrying, constantly surpassing, surpassing, and no one could say who would win in the end.

Although it takes more time to get to the next level, everyone seems to have lost track of time, and they keep glued to the screen for fear of missing out on the exciting part.

The seventy-ninth box was solved......

The eightieth box was solved......

Finally, Song Ci and the "King of Spades" opened the eighty-first box at almost the same time.

Once the box is passed, they can open the final super box.

It's dawn.

Seven hours have passed since midnight, and Song Ci has been sitting in front of the computer for seven hours in a row, and her brain is still running at high speed.

Fingertips dance on the keyboard as if they were tireless.

The last key was struck, and the screen suddenly lit up, and the box seemed to be blown open, and the fragments were scattered, and a box slowly grew larger from the middle of the screen, and the super box appeared in front of Song Ci.
