How to get the legendary water unicorn!

Athena → The Chinese New Year Lottery was randomly selected. In the past, it was necessary to replace bricks with stones, but now it has been cancelled, that is, it is out of print (I wonder if it will be published in the future).

Water unicorn → ugly card

Four Beasts → Go to the map of Qinglong White Tiger Suzaku Xuanwu and type BOSS. When prompted, BOSS will brush it out.

12 constellation → 1. Exchange copper coins for various star cards and draw them.

2. Defeating Raytheon will give birth to constellation eggs.

3. Exchange 8 bricks for any constellation egg.

4. Play more royal treasure boxes (this probability can be ignored).
