Castle in the village of Changshan County day because of weather factors,ray ban sunglasses australia, winter wheat planting is not much, or to corn and wheat based. Wu and Zhang Changshan closer than the south, so a large area planted to winter wheat. As mining smokeless Carboniferous, Zhang Wu county area, in the Hereafter is the culmination of Hebei, Cangzhou, near quite a few medium-sized ore and coal, and coal mine of course, the largest is in the later Yuxian and Handan area, but these areas are currently are occupied Schleswig, Wang Lie can only dream.
But, while we have a smoke- Carboniferous surface mine, but also cheap jordan sneakers ten meters from the ground, and even tens of meters away, under such conditions, if using artificial excavation, one time-consuming, and secondly, prisoners and criminals do not now many, mainly engaged in the production also dominated army soldiers vitality. And Wang Lie still use these soldiers to grab food production and Levee construction, future generations learn a science Nanniwan 359th Brigade. But do not want to let ray bans online energies are consumed in the Upper Carboniferous mining. Therefore, in order to maximize the conservation of human and material resources, Wang Lie thought can change this era big kill - gunpowder.
Shu Ping Wang Lie returned from the county from Cangxian after construction Ping Shu county outside the city walls had already laid the foundation,ray ban australia, a group of bluestone on the site at the time, it was ordered Wei Xiong acquisitions come from all sides. Because Ping Shu located in the plains, from where there are dozens Jimingshan distance, stone collection, transportation is very difficult. Fortunately solve transportation problems, traveling Cen joint statement after the line and, count three hundred vehicles brought from Changshan baggage car will transport to and from the stone. The main problems are still mined. If using artificial exploitation, they rely on very traditional fire water cooling method, which is to fire smoked in the rock, when the temperature reaches a certain height, then extinguish the flame, quickly poured cold water on the ready use of the principle of thermal expansion and contraction - expansion and contraction which instantly converted to produce hot and cold, so the rock cracks, and then cut along the crack, in order to obtain the necessary building stones.
