The bright route should mainly be the physics department, and the mage can also do it, but it is not as BT as the dark steel dart volley. The combination I play is swordsmen (master of spear sword, master of weapon use, master of fitness, master of spear soldier use, master of fitness increased to 20), archers (master of water and gas is enough for bows and arrows), monks (master of air avoidance and empty-handed, master of fitness) and priests (as high as light and limbs can be). The tragedy of this combination is that you are not invisible until the archer becomes an arrow, so you can't fight the tunnel and the tomb of Titan. If we can't beat Nepal, there will be no dimensional gate. After this period, as long as the archers change their posts and arrive in Nepal and behind the city, it will be easy to fight.
