E3 done when I still have 15k resource so I grinding E4 normal too hard and out of fuel after 1 day when the boss stụk at the health bar. Given up, restock to 10k fuel and switch to Easy, slowly and carefully. With the experience of E4, I go to E5 and just 3 day (9 time) to kill boss, lost nothing (daily quest/exp is enough)
