Chương 115: Finally detonated

His life profession had advanced to apprentice engineer, but he could only make ordinary bullets, which was not of much help to him for the time being.

He still had to advance his life profession to engineer.

To advance from apprentice engineer to engineer, he needed 200 proficiency points, which just happened to require two blueprints.

Zhang Shan had already prepared the level 2 blueprint and was ready to start at any time.

Of course, he couldn't do it today. He didn't have enough materials for the wooden bird and the firework. It might not even be enough to successfully make one.

It was better to wait until he had more stock. This kind of thing couldn't be rushed.

Besides, it was already very late. He had to go offline and sleep.

He stored the remaining materials and the basic incendiary bomb blueprint in the warehouse, then learned the wooden bird and firework manufacturing blueprints.
