Speaking of which, after the stone hammer tree and iron thread grass combined with Zhao Hai, although his combat power increased greatly, it was a bit of a waste for Zhao Hai. After all, the stone hammer tree and iron thread grass's ability to fight alone was also very powerful. It was a bit of a waste to let them combine with him.
However, the Ironback tree was a little different. The Ironback tree's movement was very slow, but from its appearance, it was very heavy. In addition, the Ironback tree looked like a stick, which was suitable to be used as a weapon.
