I've Been Hit by the Undead, so Why Don't I Plant Some Trees?

Are you saying that my tree planting is useless? Pull out an army of 100,000 undead with your backhand! Slap in the face + form an army alone + hide the boss "Ye Qingyun, you are awakened as a necromancer, how can you plant trees outside the city every day?!" The beautiful tutor hates iron, and the geniuses in the city regard him as a negative teaching material and ridicule him wantonly. Faced with doubts, Ye Qingyun turned a deaf ear and continued to water the newly planted saplings. They had no idea what kind of horror was buried beneath this seemingly ordinary forest. Until that day, the super-dangerous runaway copy suddenly dropped, and tens of thousands of monsters swept over the place. The mentor was desperate and the city guard was defeated. Just when everyone thought Canglan City was about to be destroyed. Ye Qingyun frowned and walked out of the wooden house, looking at the forest that was destroyed by monsters, with murderous intent in his eyes. "Dare to touch my tree? The whole army attacks!" At the command, the earth roared. Countless dark-armored warriors wearing heavy armor drew their swords and slashed the sky, and the poisonous witch clouds of the demon soul mage enveloped the sky! When I saw Ye Qingyun, one man and one army, killing the rampage copy into an empty space within half an hour. The beautiful instructor was stunned, and the geniuses in the city collapsed. "Who taught you to plant trees like this?!"
