บท 773: Shocking Strategies

After a long time, Zhang Tie finally opened his eyes.

Watching the earth-element crystal which had completely lost its golden luster and revealed its milky color. Zhang Tie faintly shook his head and forced a bitter smile. After that, he put that useless crystal on the table.

There were 7 rows of earth-element crystals on the table, 3 ones in a row. As of now, all the earth-element crystals had become as milky as that one in Zhang Tie's hand while all the pure earth elements in this crystals had been used up. These milky earth-element crystals were as useless as empty bottles.

Zhang Tie looked at the clock on the wall.

——December 29.

'I've practiced 45 days in the underground palace at the cost of 21 earth-element crystals. I've only used 1/4 of my full ability to withdraw the earth element from the crystals. If I had exerted my full effort, I would have used up 21 earth-element crystals in just 2 weeks.'
