Hard way back to Genshin Impact is an achievement from the Winner 5 section, which requires you to stop water drops from getting close to the resurgent Hydro hypostasis. The achievement reward is 5 Source Stones.
In this guide, we talked about several ways to get the achievement that are suitable for both single-player and co-op.

Location of the boss and preparation for the fight
Teleport to the north of Watatsumi Island, which is located in the territory of Inazuma. Hydro hypostasis is located underground, which can be accessed either from the sea side near the waterfall, or from the side of the island through a barely noticeable passage.
In the detachment, you will definitely need a Geo Traveler, whose comets will block the path of drops. If your hero is pumped, first remove all artifacts from him and put a weak sword on the character so as not to inadvertently kill water bubbles when setting up barriers.
You can also give the Traveler a Ceremonial Sword if you like. The passive ability of the weapon will come in handy if you still accidentally hit a comet drop by drop when you set up an obstacle. In this case, the elemental skill will instantly cool down, allowing you to quickly place Geo structures.
In addition to the Traveler, you can also take any other heroes with control abilities, such as Genie, Sucrose, Venty. They will help you stop creatures that bypassed the barrier, but be careful when using their skills, as pumped characters can deal lethal damage to the drops.
First way: single mode, elemental explosion and elemental skill
The essence of this method is to set up a barrier with an explosion of Geo Traveler's elements, and then fill in the gaps with Geo structures.
First, bring Hydro Hypostasis to a respawn state – attack him until the boss is almost out of health. Then he will teleport to the center and create three water drops around the edges of the field, which will slowly approach him.
Your task is to stand under the respawning Hypostasis and activate the Traveler's elemental explosion to form a stone wall around the boss.
There are gaps in the wall, so use Traveler's charged elemental skill to close the holes with comets.
If you are lucky enough to place the stone wall well, then you don't have to do anything else – it's enough to hold the drops for about six seconds for the hypostasis to give up and you get your achievement. But if you see that some bubble still managed to bypass the obstacles, delay it with charged attacks or any control skill.
If you're unlucky enough to hold back just one or two drops, simply bring Hydro Hypostasis back to respawn in the same battle. The boss will create the number of drops that could not be contained, and you will only have to prevent the drops from passing with the help of the Traveler's comets.
Second method: single mode and elemental skill
Considering that you don't need to hold back all the drops at once to get the achievement, you can bring hypostasis to respawn three times and hold back one drop each time.
Follow the direction of the drops, run to any one and put it in front of comet.
Soon, the drop will go around the obstacle, so you will need to install the structure again. In total, it will take 2-3 comets to stop one drop.
There is another way to stop one drop: stay close to the hypostasis and place two comets in a row in front of it. The bubble will try to squeeze between them, but if you place the obstacles correctly, it won't be able to pass.
Hystasis will then respawn with a small amount of health. Get the boss to spawn two more times and stop two more drops to get the achievement.
Third way: co-op mode
In co-op, the achievement is much easier and faster to complete, and the more players will gather – the better. All players must take Geo Travelers and use any of the methods described above. If you decide to use the second method, then you do not have to stop the drops in several stages – even together you will have time to put enough obstacles to stop all the bubbles at once.
