Bai Yufan walked around this basement for a while, and he felt bored.

Because he found that this so-called forbidden area was full of mechanical devices that he couldn't understand, and it was impossible to see a flower no matter how he looked at it.

However, just as Bai Yufan was about to leave this forbidden area, he suddenly found that there were some pieces scattered not far from him, which immediately aroused the interest of Bai Yufan and Zao Wouji.

"Hey, go over and look at the pile of debris." Zao Wou-Ki said with a little surprise.

When Bai Yufan came to the fragment and picked it up, Bai Yufan actually felt a trace of gentle energy in the fragment.

"Master, what the hell is this?" Bai Yufan asked puzzled.

"I'm afraid this is the fragment of the immortal stone left over from the Immortal Cultivation Era." Zao Wou-Ki thought for a while and said. Then Zao Wou-Ki said: "But the number is too small, and it is useless." ”

As soon as Bai Yufan heard Zao Wou-Ki say this, he immediately lost interest, after all, he only saw the fragments here, otherwise maybe it could really be of some use.

Because just now, when Bai Yufan picked up the gravel, he directly absorbed a little bit of energy inside, which only brought him a slight improvement, and he even felt that this bit of energy was not as fast as his absorption of the magic bead.

"Otherwise, you can ask that silly boy where they got these pieces of fairy stones, and maybe they can find a little surprise." Zao Wou-Ki finally decided to let Bai Yufan go and see if he could find more immortal stone fragments.

After all, it's not a big deal to ask one more sentence.

So, at the suggestion of Zao Wou-ki, Bai Yufan found Shang Jun who was still busy again, and when Bai Yufan asked about the origin of these fragments, Shang Jun explained as follows: "This thing was actually found in a ruin on the outskirts of Cave City, and at that time they just thought that this thing was going to be brought back to me for study because of its own energy, but no matter how we tested it, the final results only showed that it had a certain amount of energy." Look at 'Mao. Line, medium. Text, Net"

With Shang Jun's explanation, Bai Yufan also knew the specific location of the immortal stone fragments, but since they said that it was already a ruin, there should be no more good things.

However, Zao Wou-Ki in Bai Yufan's body didn't think so, since he could find the broken pieces, then could he also find a more complete immortal stone.

You know, now that because of the apocalypse, even the races that he thought were impossible have appeared, so why won't there be fairy stones.

"Xiaofan, you go and have a look first, maybe you can have unexpected gains." Zao Wou-Ki instigated.

Bai Yufan was really a little moved by Zao Wou-Ki's words, and after thinking about it, he decided to go there to find out.

After asking Shang Jun for the specific location, he left this ghost place without looking back, saying that it was a ghost place, mainly because although the location in it looked quite big, Bai Yufan only saw Shang Jun and the three people he was bringing when he went around.

After asking Shang Jun for a specific location, Bai Yufan left directly.

And Shang Jun and the others returned to the time when no one disturbed them before after Bai Yufan left.

In order to reach Cave City as soon as possible, Bai Yufan even summoned the fast dragon out this time.

At this time, after a few days of recovery, the strength of the fast dragon has also recovered slightly, although it is temporarily unable to release the ability like in the Blackpool Lake before.

Originally, the first thing he did when he came out was to go to Duan Jieying immediately, but he was stopped by Bai Yufan's threats and intimidation, so Kuailong could only reluctantly take Bai Yufan to leave in the direction of Cave City.

They also saw some magical beasts with flying ability and good strength along the way, but they were all dodged by the fast dragon at super high speed.

However, when they arrived at Cave City, Bai Yufan had already seen at least thirty third-order and above demonic beasts haunting.

In this regard, Bai Yufan also felt a deep pressure, he didn't expect that so many demonic beasts would appear not long after the end began, if time was pushed back a little, wouldn't there be a fourth-order.

And as long as they go further, it is the fifth order, and that is the existence that can dominate the low-level demonic beasts.

Of course, Bai Yufan could only think about these things in his heart, because what he had to do was to improve the strength of himself and the entire base as much as possible in order to survive the first wave of global beast tides after the apocalypse.

When he saw that Shang Jun was not far from the place they said, Bai Yufan had already taken back Kuailong, even though he was very unwilling, but Bai Yufan still didn't want him to be verbose.

Along the way, in addition to what Bai Yufan thought, it was the fast dragon chattering all the way, which almost annoyed Bai Yufan to death.

Looking at the countless pieces in front of him, Bai Yufan didn't know where to start, because Bai Yufan could only see the pieces no matter from that direction, and there were almost no other things.

In other words, this should only be regarded as a ruin that has emerged, and its value is basically negligible.

However, Bai Yufan seemed to have something in the dark to help him, and just when Bai Yufan and Zao Wou-Ki felt that there would be no gain, Bai Yufan finally found a few stones the size of walnuts in the middle of this ruin.

That is, these few inconspicuous-looking stones deeply attracted Bai Yufan's attention, because when Bai Yufan picked them up, he found that although these stones looked very ordinary, they contained many times more energy = energy than those broken stones.

"Looks like I've found something good!" Zao Wou-Ki said with a smile.

"Master, is this also a fairy stone?" Bai Yufan asked strangely.

"You're wrong, Xiaofan, these things are not as simple as fairy stones, I think they should be more like fairy mothers." Zao Wou-Ki said.

"Master, what is this fairy mother?" Bai Yufan asked.

Now, Bai Yufan also knew that his experience in his previous life had not brought him anything at all, because many things he had encountered since his rebirth were unknown to him, and when he encountered such a problem, Bai Yufan could only ask Zao Wou-Ki for advice.

"I guess the reason why you can feel the energy in those fragments is due to these fairy mothers." Zao Wou-Ki thought for a while and said.

"Then master, can't we still produce immortal stones with energy?" Bai Yufan said with some excitement.

And Zao Wou-Ki obviously wouldn't give Bai Yufan too many surprises, when he saw Bai Yufan very surprised, he immediately said: "You are wrong, Xiao Fan, the number of these fairy mothers is too small, I estimate that the reason why those pieces can stick to its energy is probably also formed after tens of thousands of years of precipitation." ”

After listening to Zao Wou-ki's words, Bai Yufan's face couldn't help but turn dark, he didn't expect that what he found in a hurry would not have as much effect as he thought.
