After trying a few times, it was only to extend the distance of detection to about 5 miles, but he still couldn't reach the bottom of the cave, if it wasn't for guessing that this place should have crossed the border, Fan Wu even doubted that it would go directly to the center of the earth.

The detection was fruitless, Fan Wu no longer wasted energy, and climbed into the cave himself, thinking about going down as much as possible, without leaving the controllable range, try to explore the bottom of the cave as much as possible, he didn't want to wait for Xiaozhu to be trapped in a desperate situation.

Entering the cave in person is very different from guessing outside, there is no cold and oppressive feeling here, but it is very comfortable, like soaking in the warm warm water makes people drowsy, a very magical experience.

Fan Wu didn't expect this place to feel like this, it didn't look like a cave filled with dark energy at all, if you closed your eyes, you would think that you were in a hot spring.

The feeling of physical comfort made Fan Wu feel good, and he explored down the wooden ladder and found that this cave was a bit similar to a well, and the stones on the cave wall were not very smooth, and there were not many traces of polishing.

However, it is possible that the people who built this cave at that time should have been very good at handwork, and the stones used are probably also carefully selected, and each piece is about the same size, although the shape is not the same, but the fit between them is very good, so the overall is quite regular, and there are almost no protruding corners and corners to hinder climbing.

Fan Wu went all the way down, originally wanting to go down to a distance of about 5 miles and release the current again to explore the situation below, but because it was so comfortable here, Fan Wu didn't suddenly wake up until he felt that he had a feeling of mental dissociation.

No, this is a bit similar to the cross-border feeling of the three wooden ladders above, is there another boundary to be crossed here? Fan Wu hurriedly followed the wooden ladder and returned the same way.

After climbing out of the hole, I was afraid for a while, it turned out that I had unknowingly gone far more than 5 miles just now, and now that I think about it, I may have exceeded the depth of more than 10 miles.

Originally, he thought that after recovering the black lightning, he would not have to worry about the impact of the dark smoke, but he didn't expect that this strange place would still make him almost have a way.

It seems that there really can't be any slackness here, unexpected situations can happen at any time, and it will affect your judgment and behavior without you even knowing it.

This time, it is estimated that because he has experienced the test of dark smoke before, his body has already gained resistance, so he can wake up in time when he is affected by cross-border sensations, otherwise the impact of smoke alone will not be able to stand it.

Back in the room, Fan Wu thought about it again and again, and decided not to take Xiaozhu to take this risk, he had already crossed a boundary, and Fan Wu was still worried about whether Xiaozhu's soul could find his body in time and regain consciousness.

If he crossed the realm with him again, it would greatly increase the difficulty of Xiaozhu's soul return, in case he couldn't wake up in the end, which was a result that Fan Wu didn't want to see.

So Fan Wu decided to wait for Xiaozhu to wake up, but he didn't want to continue to wait here passively, so he still had to go up and have a look.

So he followed the three wooden stairs down and tried to climb back to the stone chamber above, but halfway through the climb, he found that something was wrong, and he couldn't go up here!

It wasn't that something blocked the passage, but that he found himself crawling out of the hole in the room at his feet, as if the two holes were connected under the influence of some force.

Fan Wu tried all three wooden ladders, and the results were all the same, I don't know when this situation happened, and it felt like the two of them were trapped here.

In fact, it is not trapped, although the three wooden ladders go up, but there is no obstacle to go down, Fan Wu found that as long as you climb in, you will return to the exit of the hole in the room below, and you will not return to the room when you go down, but continue to go deep underground along the wooden ladder of the hole.

Fan Wu doesn't know, but this connection seems to be only one-way, and this situation will not be encountered when going down from the hole in the room, Fan Wu is a little confused, what kind of operation is this?

How can I just encounter these gods and strange things?

There's no way, now the two of them can't go back to it, so there are only two ways left, one is to continue to wait, wait until Xiaozhu wakes up, or wait for the passage to be restored, and the other is to take Xiaozhu through the hole in the ground to other places.

Although he didn't know where it led, it was a way out, and it might be better than waiting here, because Fan Wu didn't know when Xiaozhu would wake up, let alone if the passage would be reopened, or if it might be closed forever.

After thinking about it, Fan Wu set a time point for himself, continued to stay in the room for 1 month, and left with Xiaozhu after ten days.

Taking advantage of this 1 month, Fan Wu continued to fuse and transform black lightning, and he found that the lightning reserves on his left arm seemed to have no upper limit, no matter how much lightning he absorbed, he could accommodate it, with the thunder dragon tattoo as the center, all of them were wrapped around his arm to form a circle of black cloud-like fuzzy marks, and the energy of a power grid turned into a mark.

The first few days were just a few blurry marks that did not form a tattoo as clear as a brontosaurus, and it was not until the 10th day that the condition changed.

The imprints on his arms actually began to show signs of merging with each other, and Fan Wu had been paying close attention to the changes in the imprints, and found that the imprints had actually turned into a lightning tattoo after fusing with each other.

The lightning tattoo is only the size of a little finger, appearing on the side of the thunder dragon tattoo, and since the first lightning pattern appeared, it has begun to form continuously, all around the side of the thunder dragon, as if guarding it.

These lightning tattoos were formed by fusing the power grid imprint, and every nine imprints could form a lightning sign pattern, so the lightning energy that Fan Wu had absorbed for so long before had only formed 4 lightning bolts.

However, he found that since the appearance of the lightning tattoo, the speed at which he fused and transformed the dark smoke had greatly accelerated, but at the same time, the consumption rate of the lightning energy in his body had also increased.

Therefore, the transformation and absorption are much faster, but it takes more time to recover, so the overall time has not decreased, and it is still very sad to spend every day in recovery and consumption.

Fortunately, after the appearance of the lightning tattoo, the upper limit of the left arm finally appeared, and after more than 1 month of busy work, nine lightning bolts were finally formed, and after continuing to absorb nine black power grids, he found that he could no longer continue to absorb black lightning energy.

It seems that this is the upper limit at this stage, and it may be possible to continue to absorb the energy in a lightning tattoo after consuming it, but I just don't know if the tattoo will disappear, if not, it will be easy to do, just find a way to replenish it.

But if the tattoo will disappear, it will be a bit troublesome, it is equivalent to using one less one, and it could have been possible to try the effect here, but three days ago, Fan Wu found that the space here seemed to be a little strange, as if it was a little unstable.

The most intuitive thing is that the free energy floating in all corners of the room seems to be starting to leave this space, three days have passed, there is almost no free energy in the room, and it is difficult for Fan Wu to replenish the consumption through self-recovery.

In addition, it had already exceeded the time set by himself, so he simply didn't waste energy and time here, and immediately picked up the small bamboo on his back and climbed down the wooden ladder from the hole in the ground.

This time, I paid special attention to the changes in the environment inside the cave, and when I climbed to a depth of about 5 or 6 miles, I felt like I crossed over again, so it's no wonder that I landed unconsciously last time.

At that time, it was estimated that I was too comfortable to enjoy it, and I didn't realize that I had passed the distance of 5 miles, so I was a little confused.

This time it's different, I was mentally prepared before I set off, and I had to pay attention to the small bamboo behind me during the climb, and my spirit was highly concentrated, so it was not very affected.

And the most critical point is that Fan Wu released a faint electric current from the beginning of his departure, extending it to a distance of about 1 mile below his body for pathfinding.

It doesn't attack and consume any smoke, it's just an extension of your senses, and you don't want to be able to find anything, it's just similar to the function of a flashlight, which can light up the front a little.

Carrying Xiaozhu all the way down, Fan Wu felt that he had climbed dozens of miles deep, but he still hadn't reached the end of the hole, as if this hole was an infinitely extending passage.

But Fan Wu also knows that this kind of cross-border passage cannot calculate distance in terms of time and feeling, because in the process of cross-bordering, time and space have little meaning.

It feels like I've climbed dozens of miles, but in fact, it may only be a few hundred meters, or maybe it's already a few star fields.

Whatever, it's already in anyway, and now I can only continue to climb, I don't believe that it can really be infinite, and with a tight grip on the small bamboo tied to his body, Fan Wu sped up a little.

But Fan Wu may have overestimated his luck a little, and continued to climb for a long, long time, he felt that he estimated that it had been almost a few days, and he still hadn't reached the bottom of the cave, this time Fan Wu was not only a little hesitant at first, but also a little dizzy.

Because staying in a cross-border environment for a long time will have a huge pressure on the spirit, otherwise there is no need to climb several times on the three wooden ladders above to get used to it.

At that time, the time of the process was still very short, so he was allowed to climb twice to get used to it, and this time he had to stay in this environment for several days, which was a great burden on his spirit.

The key is to pay attention to the small bamboo tied behind his back, and try to maintain the stability of the two of them not to fall, it takes a lot of energy to both physically and mentally, and Fan Wu is also starting to be a little unbearable.

After continuing to climb for half a day, his spirit began to be a little unfocused, and his consciousness began to be a little blurry, Fan Wu paused, rested a little, lifted his spirit, and felt better before continuing.

After a long time of crawling and stopping, they finally couldn't support it, and as soon as their hands were released, the two of them became free fall and fell down at high speed.
