Zhao Hai was right. The next ten days would be the most important ten days for them. If they couldn't survive these ten days, they would be finished. If they could, it would be a different story.
In fact, neither Qing Lan nor Zhao Hai wanted to contact the big sects because they knew very well that once they contacted the big sects like the ten thousand Buddha Temple or the Tianyi Dao sect, it would be equivalent to giving away their territory. They would have nothing but a chance to live. Those big sects would not negotiate with you. They had the strength, so they would not negotiate with you. Therefore, Zhao Hai and the others wanted to rely on their own strength to get through this.
