In order to prevent the Demon Head from escaping, the formation Token of the eighteen levels of prison was held separately by all the righteous gods of the Heavenly Prison, and it could only be opened when activated simultaneously.
Upon hearing this, Colonel Niu and the others did not think much and directly handed over the Token to Sun Changsheng.
This was not the first time for such an event, and there had been no issues with the Heavenly Prison for a millennium. The rules set in those days had slackened to the extreme. For example, officials privately contacting prisoners was also a violation of the heavenly decrees, but now it had gradually become a habit through subtle influences.
Sun Changsheng entered the eighteenth level of prison and activated the Prohibition Token to open one of the cells.
