Upgrade the Eyes of Truth; Join Them!

Then, Lin Fan's gaze landed on the double skill card and the skill level upgrade card.

[Double skill card: You can double the ability of a certain skill for an hour. You'll possess more powerful skills and display more charm.]

[Skill level upgrade card: You can upgrade a skill level. Mastering even more profound skills will make you more fascinating.]

Lin Fan was very familiar with these two cards.

It was because he had used them before.

Even before Lin Fan opened the 15,721 red packets, he already had two double skill cards and one skill level upgrade card.

The double skill card had a time limit, so Lin Fan had not used it yet.

As for the skill level upgrade card, he only had one for the time being. He wanted to save it for when he needed it and be more selective with the skill he chose so as to be prepared.

Now, he could use one of them.

Hence, Lin Fan turned his attention back to the system.
