Hello, I am happy to answer your questions:

You can choose to keep it and strengthen it later. .

You can choose to keep it permanently, considering that you will need to fight the magic tower later

When it comes to fighting the magic tower, I have come up with several methods for you:

1 The third line + brazier is the main attack, and the egg is the assist (it is recommended to recharge in a single transaction, and you will get 9 stars for the third line full-time)

2 The main attack is the water pipe + the brazier, the egg is the assist

PS: If you If you want to hit 40, we recommend:

1. 9 on eggs

2. 8 on production types

3. 7 on bomb cards

Now, the effect of matching 8 and 9 braziers on the third line is pretty good
