Ten days passed!
At this time, Feng Yun and Long Shu were standing in air above the Gu City. Huang Xiaowen was constantly running in the city here and there. After half an hour, he finally stopped. Arriving in the middle of the City, he slapped hard into the ground using his spirit qi.
Suddenly something in the city, a wild tremor appeared in the ground, the spirit Qi around the city started fluctuate madly. Soon, the surrounding spirit energy started moving towards the Gu City.
It continued for ten minutes before everything returned to normal.
"Here it is! I have placed three great formation, around the city; a defense formation, spirit gathering formation and lastly a great protection formation. I have connected formations core to the Spirit Vein unless the spirit vein go dry you don't have to worry about expenditure to run the formations." Huang Xiaowen said as he waved his hand lightly.
