More than ten days have passed in the blink of an eye, Xiao Yufan has never thought about leaving this place at all, and even because he is too devoted to studying the two powers after "Chongxia", he has almost no concept of time.

It wasn't until the communication bead left for him by Tuo Qianli in his arms suddenly shone that Xiao Yufan realized that it seemed that he should also go out from here.

Now Xiao Yufan has fully mastered the power of the flying sword Chongxia "Qianxia Sword Rain" and "Piercing One Blow", the former is a group attack, and the latter is a single body, which can complement each other.

And the third power of "Chongxia" "Xia Explosion" has not been fully mastered so far, and it can barely be regarded as a peek at the door.

The transmission bead given by Tuo Qianli lit up, indicating that he had found the location of the spiritual vein hidden in the Nine Tribulations Medicine Realm, and was about to take away the spiritual vein, and he needed Xiao Yufan to rush over to help protect the Fa.

In line with the trustworthy principle of accepting money from people and eliminating disasters with others, in fact, with the curiosity of seeing what the spiritual veins look like, Xiao Yufan activated the teleportation array and left the spiritual root blessed land.

When Xiao Yufan appeared on the edge of the deep pool with all his vigilance, those monks who he estimated might be waiting for him to appear here didn't even see any of them, not even half of them.

"It's been seventeen or eighteen days, and it's normal that no one is guarding it."

On the shore, Xiao Yufan snorted, took out the communication bead in his arms, and contacted Tuo Qianli.

"Xiao Daoyou, I've found that spiritual vein!"

It is not difficult to judge from the trembling timbre of Tuo Qianli how excited he is at this moment.

"Tell me where you are, and I'll come here. Xiao Yufan said directly.

"Good. ”

Tuo Qianli quickly informed Xiao Yufan of the location, and said: "Xiao Daoyou, there are still some changes, I will tell you in detail when you arrive." ”

Xiao Yufan heard a trace of uneasiness and nervousness in his tone, although he had doubts, but Tuo Qianli didn't say anything, so he didn't ask any more.

"No matter how much it is, let's meet him first. ”

Tuo Qianli told Xiao Yufan that his location was in a huge karst cave in the southeast corner of the medicine realm, not too far from the Bailing Pond where he was.

About two hours later, Xiao Yufan arrived.

What caught his eye was a huge sinkhole, half a mile in circumference, and at a glance, it was bottomless.

There are many second-order elixirs growing around the sinkhole, and now, these elixirs are no longer in Xiao Yufan's eyes.

Before coming here, Xiao Yufan recalled that the data was described in detail, and there was no record of this sinkhole, and it was obvious that this was an area that had not been developed by previous people.

And to be honest, the location of this sinkhole is indeed biased enough, if it weren't for Tuo Qianli to give the exact direction, and told Xiao Yufan how to move forward at some turning points before some dead ends several times.

Even if this destination is clear, Xiao Yufan may not be able to arrive so quickly, and he will even think that there is no such sinkhole at all.

The probe swept the pitch-black sinkhole in his eyes, Xiao Yufan jumped in a loud voice, lifted his breath, and slowly fell towards the bottom of the pit.

The slow descent lasted for a whole incense stick, and Xiao Yufan was down-to-earth, raising his hand and throwing out a fireball technique to illuminate the surrounding space, and found that the surroundings were covered with dense corridors like spider webs, and the number was no less than hundred.

"Xiao Daoyou, is that you?"

Tuo Qianli's slightly nervous voice sounded not far away, and a probe came out of one of the corridors.

Xiao Yufan saw Tuo Qianli's nervous look, and couldn't help laughing: "Why is Tuo Brother so nervous, such a deserted place, except for you and me, it seems that no one else can find it." ”

After seeing that the person who came was indeed Xiao Yufan, Tuo Qianli hurriedly stepped forward, and said with excitement in his eyes: "Xiao Daoyou, you come with me and take you to see a good thing." ”

Xiao Yufan was also accustomed to the former's surprise at a glance, and immediately followed him and walked straight towards the road where he had just appeared.

After entering the Yongdao, Xiao Yufan realized that he had just underestimated the complex terrain at the bottom of the sinkhole, and almost every thirty or fifty zhang forward, there would be three to nine forks.

Thousands of roads as complex as a network have built the underground into an incomparably huge labyrinth, and I really don't know what this extension relies on to be able to discern the direction.

I don't know how many underground roads I have passed, Tuo Qianli's rapid pace finally slowed down, and when he came to a three-way crossing, he pointed to the leftmost road with a hidden light inside, and said excitedly: "Xiao Daoyou, I found that spiritual vein, and not only found it, I also locked its chakra, right there, but now there are two unexpected situations beyond my expectations, it will be more troublesome."

"Tell me about it. ”

Following Tuo Qianli all the way to the shuttle, Xiao Yufan was not in a hurry, and said calmly: "If it is within my ability, you can help me." ”

Tuo Qianli didn't expect Xiao Yufan to be so easy to speak, and he was still a little hesitant, but when he heard this, he immediately spoke: "First, this spiritual vein hidden in the territory of medicine is no longer a low-grade spiritual vein. ”

"What? do you mean it's a mid-grade spiritual vein?"

Even if Xiao Yufan had kept his composure as much as possible, he couldn't help but exclaim, the gap between the low-grade spiritual vein and the middle-grade spiritual vein was too huge.

The spiritual veins are divided into the best, the upper grade, the middle grade, and the lower grade, even if the lower grade spiritual veins are ranked at the bottom of the rank, it also contains a huge wealth of hundreds of millions of spirit crystals.

Often, a low-grade spiritual vein can support a small sect for thousands of years, which shows its preciousness.

And the middle-grade spiritual vein is even more remarkable, the spirit crystal resources contained in it are at least ten times that of the lower-grade spiritual vein, and there are many rare refining materials in it, and the value is immeasurable.

A medium-grade spiritual vein is enough to arouse the covetousness of any major sect, and it may even launch a small-scale fire merger in order to compete for the spiritual vein, even if it is a great power in the god transformation stage, it will be tempted by this.

Just when Xiao Yufan was shocked and surprised, Tuo Qianli responded with a trembling voice: "It can no longer be regarded as a medium-grade spiritual vein."

"It's a quasi-high-grade spiritual vein!"

As soon as these words came out, Xiao Yufan's eyes suddenly widened, and he shook his head vigorously to prove that he was not dreaming, and asked again: "Brother Tuo, are you right?"

When Tuo Qianli heard this, he immediately said in an extremely professional and confident tone: "Xiao Daoyou, our Tuo family has been inherited for more than 100 generations, and in terms of judging the grade of the spiritual vein, no child of the Tuo family has ever made a mistake, I can conclude that this is a quasi-high-grade spiritual vein." ”

"According to my estimates, if this spiritual vein is given another three to five thousand years, it is very likely to evolve into a high-grade spiritual vein. ”

"However, you told me before that the distribution map left by your Tuo family ancestor shows that this should only be a low-grade spiritual vein, and the gap is inevitably too big. ”
