In an ice coffin at the end of the cave, Tang Fei found the spirit fruit.

In the entire ice coffin, there are six spirit fruits, these spirit fruits are the essence of this extremely cold dense forest, and the significance to monks and immortal cultivators can be imagined.

Compared to ordinary spirit herbs and elixirs, spirit fruits can be directly devoured by immortal cultivators and improve their strength.

Of course, for alchemists, directly devouring the spirit fruit is tantamount to destroying the heavens, because the spirit fruit has endless spiritual energy, which is a more pure and powerful force than the true qi, so the spirit fruit can be used to refine the Gathering Spirit Pill, Pei Yuan Pill and even Nirvana Pill.

The Gathering Spirit Pill is of great benefit to both monks and immortal cultivators, which can maximize the cultivation of the user and make up for the dark injury.

The effect of Pei Yuan Dan is much more powerful, and it is only suitable for monks who have reached the Hongmeng realm, and it can help the monks of the Hongmeng realm break through and become immortal cultivators.

As for the Nirvana Pill, it is only suitable for monks in the Dan stage, which can greatly increase the probability of forming the Nirvana Golden Pill.

Whether it is the Juling Pill, the Pei Yuan Pill or the Nirvana Golden Pill, although the objects that can be taken and the effects achieved are different, one thing is the same.

That is, these kinds of pills are extremely precious, and their value is simply priceless, or in other words, they can be met but not sought!

It seems that if he uses these spirit fruits to refine some top-grade pills, the strength of the people around him will definitely increase exponentially.

After taking all kinds of spirit fruits, Tang Fei did not rush into the Lost Battle Realm, but directly at the entrance of the Lost Battle Realm, he began to refine the pills.

With Tang Fei's cultivation at this time, if he wanted to refine the pill, he no longer needed an alchemy furnace.

But he still took out the Qingluan Fire Phoenix Ding from the space ring and used it to carry the medicinal herbs.

There were countless elixirs in his spatial ring, Tang Fei directly took out the important materials, threw them into the Qingluan Fire Phoenix Ding, and then directly covered them with the Heavenly Rank Holy Fire.

Then, he directly controlled the Heavenly Rank Holy Fire with his divine thoughts, removed the dross from the elixir, and condensed the essence part.

Half an hour later, Tang Fei stopped.

Several people were extremely surprised to see that there were already dozens of pills in their Qingluan Fire Phoenix Ding.

These dozens of pills are divided into two colors, namely red, blue, and yellow.

The red one is the Juling Pill, the cyan one is the Pei Yuan Dan, and the yellow one is the Nirvana Pill.

Xu Qing and the others were even more shocked in their hearts, originally, Tang Fei's ability to refine pills with his divine thoughts was terrifying enough, but they didn't expect the other party to refine several pills at once.

Seeing that the other party's control of his own divine thoughts has reached a very precise state.

Taking out four Gathering Spirit Pills for Xu Qing to swallow, Tang Fei teleported back to Jiangyou County, leaving a part of the pills to the woman and the Hidden Dragon Clan.

He believed that with the assistance of this top-level elixir, his woman and the members of the Hidden Dragon Clan should be able to give birth to a powerhouse of the Hongmeng Realm, so that even if there were any variables in his entry into the Abandoned Battle Realm, he didn't need to worry too much.

He didn't linger too long, and after putting down the pill, Tang Fei teleported away and returned to the location of the abandoned battle realm.

Immediately, the group stepped into the abandoned battlefield.

The entrance to the Lost Battle Realm is the spiritual spring in front of you.

Everyone dived into the spiritual spring, and after moving forward for a certain distance, the space in front of them changed instantly.

Immediately, everyone stood in a completely different space.

Here, there are ruins and debris everywhere, and the alien plants that cover these ruins.

"The entrance to here from the outside is fixed, but from the inside to the outside, the exit is hard to find, in fact, I found the black box ten years ago, but after ten years, I used it to find the exit. ”

Su Mingzhi raised his eyes and said with emotion.

Tang Fei spread his divine thoughts, and in the blink of an eye, he covered a hundred miles in a radius.

Within a radius of a hundred miles, there were no other living creatures except plants.

"Are there any beasts in the Forsaken Battlefield?"

Tang Fei couldn't help but ask Su Mingzhi.

"There are wild beasts, and they are all weird-looking, I used to fight monsters a lot, but for some reason, these beasts became fewer and fewer, and in the end, these beasts were rare. ”

Su Mingzhi replied, thinking about it now, he also felt strange.

After all, if it was because of the change in the environment in this abandoned battle realm, some animals would go extinct, in this case, Su Mingzhi would also encounter danger.

Of course, it may also have something to do with Su Mingzhi's increasing strength in the later period.

Tang Fei didn't continue to ask any more questions, and started the search work.

In front of the eyes of several people, the world is also a vast world, the difference is that the world has collapsed, the city has been destroyed, and there is almost no living thing to see except for a few plants.

In such a world, it is indeed not a simple matter to find the black box.

The reason why Su Mingzhi was able to find the black box before was purely because of luck.

Once, the other party fell into an ice cave, and there were many dead people in the ice cave.

Because it was the relationship between the ice caves, none of the dead people inside were rotten, and from these dead people, Su Mingzhi searched for the first black box.

Originally, Su Mingzhi thought that he could find the secret of the lost battle realm from the black box, but he didn't think that there would be a second black box.

"Is this possible, but the world has been attacked by terror, and the humans here know that they will not be spared, so they have stored some information through several black boxes. ”

Tang Fei reasoned so.

At this time, Xu Qing nodded and said, "I think this is very likely, but I think that the reason why this information is packed into several black boxes is not intentional, but because the space for each black box to store information is limited." ”

Xu Qing's reasoning is very easy to understand, just like the storage space of mobile hard disks, the capacity of each hard disk is fixed, if the things that need to be stored exceed the storage space, it can only be stored with multiple mobile hard disks.

"You've cracked the contents of the first black box, and you think it's going to take all the information you need to produce that powerful weapon. ”

Su Mingzhi was inspired by Xu Qing and couldn't help but ask.

Tang Fei thought for a moment and said, "Based on my perception, I need at least twenty black boxes. ”

Hearing this, everyone immediately fell silent.

In this vast and boundless world, finding a black box is tantamount to looking for a needle in a haystack.

And twenty black boxes are equivalent to finding a needle in a haystack twenty times.

At present, the alien demon kings who were sealed by Hongmeng Tianzun with magic circles will come out at any time, bringing disasters to the world, and in two years, a hundred alien demon kings will "visit" the earth.

It is simply impossible to find the black box in such a short time!
