While manipulating the wheelchair, Qianwen also had to deliver spiritual power to the polar detector. Fortunately, there is not much spiritual power to urge these two things, otherwise such continuous consumption will be able to squeeze the dry questions dry. But what made Qianwen happy in his fatigue was that he also found some yin and yang qi. Although this is not enough to evolve the I Ching, it can still add up to a small amount and increase the power of yin and yang shocks.

"Xiao Hei, we've already searched for a quarter of the Night Forest, but we don't have a strong polar aura, what should we do?" said Qian Wen, who was weak. This long-term output of spiritual power also had a certain impact on his spirit.

"Come on! Persistence is victory! This huge amount of spiritual power output and reabsorption will also be beneficial to your cultivation. Hold on a little longer!" said Hei impatiently. But looking at his graceful appearance, it is obvious that he is suffering from Qianwen, but he is very comfortable.

"You ......" Qianwen was about to attack, but a voice broke his thoughts......

"Didididi, Dididi......"

Listening to Qianwen, he was overjoyed. The four consecutive "drops" indicate that there is a fourth-class rich polar qi appearing!

The polar gas detected by the polar detector is divided into one to nine grades, with the first being the thinnest and the ninth being the richest. Generally speaking, the first to third class occurs the most. And now that there is a fourth-class, how can this not make Qianwen happy!

Qian Wen hurriedly looked down and found that the ball had changed from transparent to a black bead directly in front of him. The black dots represent the yin and evil energy, while the white dots are the yang energy.

"There is a fourth-class evil aura right ahead!" Qianwen told Xiao Hei.

"Then hurry up!" Xiao Hei smiled and urged.

Qianwen glanced at Xiao Hei, raised the speed of the wheelchair to the extreme, and flew away......

............

To the east of the forest at night, a team of men and horses was digging down for something. Seeing his clothes, it was actually the people and horses of the Biyan Sect in Liuhuang City......

"Hurry up, dig quickly, otherwise the young sect master will come and punish ......"

"Hey, this young sect master doesn't know what to smoke like crazy, and he wants us to dig this place where birds don't......"

"Shh......h Be quiet!I was heard by the young sect master, but you have a good ......."

The sound of bells and bells constantly sounded in the crowd. And the dripping sound of the two-pole detector is getting louder and louder. The small black ball, which is also getting closer and closer to the center......

A few minutes later, Qianwen arrived in the area. But what made his brow furrow was the words of the people over there......

What kind of thing are you, we are the people of the Biyan Sect of Liuhuang City. We have covered this area, and idle people are not allowed to enter!Do you want to disobey the orders of our young sect master?" he said in a loud voice with a sneering look on his face.

"The Biyan Sect of Liuhuang City?" Qianwen thought for a moment. It seems that next to Cloud Studios is a place called Liuhuang City. These two places are separated by a forest of night. No wonder, the people of Liuhuang City will also come here!

"Blackie, what should I do? It seems that they are also looking for the source of that evil aura. Qianwen's face was calm, but he was anxiously asking Xiao Hei in his heart.

"Heroes don't suffer immediate losses, don't conflict with them first. After all, if you fight so many people alone, the winning rate is not high. Besides, you still have mobility problems, so it's better not to make enemies for the time being. Xiao Hei analyzed the situation in front of him and said in a deep voice.

"Then what should I do? With such a strong yin aura that I finally found, wouldn't I want to give it to others for nothing?"

"Fourth-class yin and evil qi, how can it be so easy to find. When night falls, we'll figure it out. Xiao Hei smiled again, "Don't forget, at night in the Night Forest, there are a bunch of spirit beasts!"

In an instant, Xiao Hei's thoughts were already clear to him. So, he pretended to be unintentional and said to the person in charge:

"Sorry, I just didn't mean to break in, I'll leave right now!"

Suddenly, Qian Wen frantically urged the only remaining spiritual power in his body, and manipulated the wheelchair to sweep into the distance......

"Hmph, count you as acquaintances!" the man snorted, and turned back to monitor the movements of the men......
