Krune's group was quite lucky this time since they found a door in just a few minutes. This door in specific had exactly four slots, which is the number of Krune's group. At least at the moment, Krune's group was the only only one here, and no one else appeared. Of course, the 98th level had just opened, there is still some time before the next level opens again.
Since there was nothing to do during the time being, Krune decided to try to use Tribulation lightning in the Hydrogen and Oxygen separation. He started to control it the same way as he did with his normal Lightning Element. But just as he started, the two poles lost control, and the process failed right there and then.
"As expected, Tribulation Lightning is really a lot more difficult to do such a fine control than normal Lightning Element."
