Chapitre 1301: Exiting Castle of Black Iron

When a 680 kg golden spear hit onto the ground which was covered with holes at a speed of over 9,000 m per second, it released over 27 billion Joules' kinetic energy. As a result, it caused an earthquake and a terrifying big hole on the ground in a split second. Its impact wave reached over 2,000 m away with great destructive power.

Before the golden spear's impact wave completely disappeared, a figure in pitch-dark battle armor had hit 3 over 100 m higher mountain peaks forcefully with his 6.8-ton battle hammer at the speed of over 6,600 m per second, releasing over 140 billion Joules energy once again. 

The impact of the later strike was much greater than that of the golden spear. The entire earth was quaking. Additionally, a huge mushroom cloud rose up. After everything became quiet, the figure in pitch-dark battle armor nodded in the sky before shaking his head.
