The transaction has two unconfirmed children. So, for replacing that transaction with a new one, nodes have to remove three transactions from their mempool.
The fee you pay for the replacement transaction must be higher than the total fee paid for those three transactions added by minimum fee required for relaying the replacement transaction.
The total fee paid for those three transactions is 101,611 sat.
The minimum relay fee rate for nodes with default setting is now 1 sat/vbyte and the minimum required fee for relaying the replacement transaction is 788.25 sat.
Therefore, the fee you have to pay for the replacement transaction must be at least 102,399.25 which gives the fee rate of 130 sat/vbyte.
So, if you want to replace the parent transaction with a new one, you should increase the fee rate to at least 130 vbyte.
Take note that you may need to increase the fee rate a bit more, since nodes may have different settings.
Since paying such fee may be expensive for you, you may want to consider waiting for the original transaction to be confirmed.
