Xia Xin walked non-stop, in the direction of the Qifan Auction House, and when he reached the entrance of the edge of the open-air basin, he became cautious and began to hide his traces. Pen & Fun & Pavilion www.biquge.info

"Master, they should have cleared all the hidden dangers before leaving, but I'd better be cautious, in case there is a fish that slips through the net." Xia Xin looked down, a ruin came into view, there was no life, and no one approached this area, which made Xia Xin confused, it stands to reason that there should not be no one, at least there will be that kind of scattered cultivation to explore the treasure, right? But his mind passed, and he couldn't feel any breath, suddenly, Xia Xin's eyes lit up, and he saw a stone tablet above the left, with these four words on it.

"Intruder, die!"

When Xia Xin saw the last dead word, he kicked and kicked, took a few steps back, his face was so white that he almost didn't spit out blood, and at the same time his heart was sensational, as if he had a sledgehammer bombarded his heart.

"This... This is?" Xia Xin clutched his chest, but he didn't dare to look at the stone tablet again, but he felt a familiar breath from it, with the power of the mysterious stars, undoubtedly, it was Cheng Hui's handwriting.

Xia Xin crossed his knees, and only after half an hour did he lower the tumbling qi and blood pressure, fortunately, he didn't look at it for long, otherwise this death would be too wronged, there is nothing here except the stone stele, and standing here can't achieve the goal, just when Xia Xin wanted to jump down, suddenly a light film appeared out of thin air, covering the entire open mouth, which made Xia Xin suddenly realize, no wonder no one came, this stone tablet and barrier must have been laid by Zheng Yin and Yang before they left, in case something happened.

"It's best for this thing to be made by the master.." Xia Xin secretly prayed, he silently ran yin and yang, there were some changes between his pupils, and a few black and white beams shot out, hitting a thin barrier on that surface, but to Xia Xin's disappointment, after the beam rushed into the barrier, there was no change, like a mud cow entering the sea.

After his eyes returned to normal, Xia Xin tried to contact the barrier with things such as sealing words and yin-yang pools, but the result was still the same, which made him extremely frustrated, since Zheng Yinyang did this, or allowed others to do this, it was very likely that the things in it would be intact, but the problem was that Xia Xin couldn't take it away if he wanted to, and he was also blocked out.

"Hey, I don't know if this is feasible?" Xia Xin didn't retreat easily, after pondering for a moment, he had a flash of inspiration, and said to himself with a light smile, only to see him emit a yin and yang pupil again, and he drove the seal to hang it above his head, and then he tentatively stepped on the barrier with his foot, this time there was no sense of blocking, and his foot blended in.

Xia Xin felt very happy, and his heart was extremely moved, this was undoubtedly laid out by Zheng Yinyang, but the design was quite exquisite, as if it was specially reserved for him.

Xia Xin stood in place, bowed to the barrier, thanked him silently, and then stopped procrastinating, took back the Yin-Yang Pool to the empty ring, sealed the words on his head, and shot his eyes with pupils, and jumped down like this.

Entering the venue of the Qifan Auction House, Xia Xin did not hesitate, and walked straight to the entrance to the underground, but after arriving there, he found that it had been completely filled, which made him frown, and he felt as if he had fallen more than a thousand feet that day, so deep underground, if he wanted to make a hole to enter, it might really take some time.

"Whoosh.."

"Who?" Xia Xin turned around and shouted in an instant, but he didn't see anyone or anything, except for ruins or ruins, but he was vigilant in his heart, he couldn't hear it wrong, his mind moved, and his mental power poured out, covering almost one-tenth of the entire auction venue at once.

"Could it be that I'm suspicious?" After a stick of incense, Xia Xin became suspicious of himself, under his carpet search, there was no breath of any living being, was it really that he thought too much? Xia Xin shook his head and withdrew all his mental power, such a large-scale exploration, he couldn't use it for too long, and the mental power consumption was easy to be excessive.

At this time, Xia Xin regretted it a little, he should have brought the Eye Demon, but the question was how could he want to get these in the temple? No way, it's all here, and returning empty-handed is not what Xia Xin wants.

"Unexpectedly, Ben Shao also had a day to be a mouse. Xia Xin muttered self-deprecatingly, and even slammed his fist to the ground, smashing out a big hole, he looked at this pit, and a black line came out, this method doesn't work, the area hit is too large, if you really want to keep fighting like this, it will have a bad impact on the entire Heavenly City.

Xia Xin didn't do anything brutally, and then pinched the trick with both hands, stretched out a finger, and the fire on it was revealed, under his control, it turned into a small fire knife, and then his mind moved, the fire knife went straight into the ground, and it was like cutting tofu in a circle, just three breaths, and a three-foot pit that could accommodate two people standing back to back appeared in Xia Xin's eyes.

"It's a lot simpler. Xia Xin showed a satisfied smile, and secretly rejoiced in his heart, fortunately, in addition to a layer of ice on the surface of Tiancheng, all the ground under it was soil, if it was the same as the thick ice outside, then Xia Xin felt that he should go back to the temple and bring the eye demon.

After that, Xia Xin followed this method and used the fire knife to cut holes, and he didn't have to worry about the soil that was cut off, because the temperature of the fire could evaporate it, of course, the fire knife itself was slowly becoming transparent, and it was completely dispersed after cutting it more than ten times.

"Three meters with a fire knife, that's too slow. Xia Xin felt that if he followed this rate, he wouldn't want to go to Nanchuan tomorrow, and then the fire knife formed by the fire spirit power was extended to one meter, so that the efficiency was much higher, one meter at a time, a fire knife ten meters, about five breaths.

"Seventy meters. ”

"One hundred and thirty meters. ”

"Two hundred and forty meters. ”

In this way, Xia Xin made holes little by little, and in the process, he found that he was more and more comfortable with the control of fire spiritual power, which was an unexpected joy, and it also made him more tireless, and even later increased the fire knife, two meters, three meters, until ten meters He did not stop, familiar with the control of this length for the fire knife.

Because every time one meter increases, the temperature of the fire spiritual power rises a lot, which is stronger and greater for the evaporation and destruction of the soil, and if one is not well controlled, it may cause a collapse and bury him in the ground.

"Seven hundred and fifty meters. ”

"Nine hundred and eighty meters. ”

"One thousand and one hundred meters. ”

In the back, Xia Xin's speed of digging holes is getting faster and faster, but he is no longer just digging holes, but most of his mind is focused on controlling the fire spiritual power, he really wants to reach the point of Chijun, giving the flame a spirit, a gigantic, and god-like, but at present, he can only do the most ordinary changes.

The first technique of fire control, all things! Make the flame change all things, all things here are dead things, things without spiritual intelligence, things like flame threads, fire swords, fire knives, and so on.

"1,300 meters. ”

"Seventeen hundred meters. ”

"Nineteen hundred meters. ”

Xia Xin exhaled lightly, more than an hour had passed since the beginning, and the length of the fire knife had also increased from ten meters to thirty meters now, he took a short rest and began to work hard again.

"Two thousand one hundred meters. ”

"Two thousand four hundred meters. ”

"Two thousand eight hundred meters. ”

It wasn't until he was two thousand nine hundred and ninety meters that Xia Xin stopped, because he saw a small hole in the wall exposed, which made him understand that it was almost there, and he didn't immediately do the last digging, but crossed his knees to recover.
