How to transfer Neurolink to minimize costs

How to transfer Neurolink “correctly” to minimize costs?
A:

After unlocking the 4th and 5th slots, reroll without locking other slots until you find atk% or crit chance% (Lizzy only) in the 4th or 5th slot at epic level or higher.
If the attribute appears in the 5th slot, block it and continue rerolling until you find atk% or crit chance% in the 4th slot.
After that, block the 4th and 5th slots and start looking for flat atk in 1-3 slots.
As you find the required attributes in slots 1-3, block them one by one along with the 4th and 5th slots.
Key Point: Don't block anything until you find atk% or crit chance% in the 4th and/or 5th slots. These attributes are only available in slots 4 and 5; they are not available in slots 1-3.
