The boundary was the boundary between the human world and the heavenly world.
Normally, it was impossible to cut off the boundary, but the boundary of the eight desolates world was different. From the beginning, Chen jingzhai had set it up with the minor heaven cloud restriction.
After that, he gathered the great heavens cloud restriction and used it to block the nine layers of the sky of flames. The Xiantian Qi and Origin Energy of the human world passed through the boundary.
In other words, it tempered the boundary between the two worlds, and the two energies were so magical that they completely merged the forbidden clouds of big and small heavens, forming a super-strong boundary film.
In this way, the connate gold and coin ancient tree planted on it could leave at any time. Chen jingzhai would activate the heavenly Dao clone and mobilize the power of the world to separate the heavenly court.
