If you want to become an immortal, go to the 100th level

Lu Pingxi was still so cautious. If he could, he wouldn't even open the iron box, but if he didn't open the iron box, he wouldn't be able to get the clues inside.

So Lu Pingxi set up a formation, stayed ten meters away, and used his magical power to control a knife to open the iron box.

This knife is also a demon bone knife. At present, Lu Pingxi's weapon refining materials are all from the bones of demon beasts. I heard from the little flower demon that some rare weapon refining materials will appear after the tenth level.

According to the little flower demon, those above the tenth level can be regarded as cultivating immortals. Qi training below the tenth level is just a foundation. Most monsters rely on brute force to fight.

Therefore, human beings now have not even entered the threshold of cultivating immortals.

Lu Pingxi carefully drove the bone knife to cut open the iron box. The bone knife was very sharp, and Lu Pingxi used his magical power to cut open the iron box easily.

During the whole process, Lu Pingxi was very careful, his movements were very slow, and his body was ready to escape at any time.

But this time it was Lu Pingxi who was overly worried. There was obviously no trap in the iron box. It was just an ordinary iron box. But Lu Pingxi was still worried. He said to Su Yu: "Wait a moment, I will arrange a few more." A formation to ensure nothing goes wrong!”

As he spoke, Lu Pingxi arranged a new formation on top of the original one.

Su Yu was a little speechless. This is just an ordinary iron box!

Lu Pingxi continued to arrange formations, all of which were defensive formations. Lu Pingxi said: "Three earth-attribute defensive formations may not be safe. Please wait a moment, and I will arrange three more water-attribute buffer formations."

Two minutes passed, and Lu Pingxi spoke again: "Don't be careless. The opponent might really be a monster in the Nascent Soul stage. Just wait a moment, and I will arrange three more wood attribute damage absorption formations."

Five minutes passed. Lu Pingxi was still planning to set up the formation, but Su Yu reminded: "Our actions may be noticed by other adventurers. If we continue to delay, we may be discovered by other adventurers."

After hearing these words, Lu Pingxi stopped and said, "It makes sense, the formation is enough, I'm going to open the box!"

Just now we just cut open the iron box, now is the most important thing to open the box!

Lu Pingxi controlled the demon bone knife, and then gently opened the iron box. Then, nothing happened. This was indeed an ordinary iron box, but Lu Pingxi was not yet at ease. He carefully removed the contents of the iron box. Things were poured out, and then Lu Pingxi and Su Yu saw a document that had been poured out, and a small wallet.

Su Yu became confused: "This is? ID card?"

Lu Pingxi walked over and observed carefully through the many formations. He said: "The ID card that records Tina's information on it does not look like a forgery. Strangely, this Tina seems to have come from the outside world." Entering the Tower of Immortality.”

Su Yu asked: "Is it true that she was captured by the monster?"

Lu Pingxi frowned: "I have doubts. Since they were captured by monsters, why are these things hidden here? On the contrary, I think they are hidden here because they are inconvenient to carry."

Su Yu asked: "Would a monster of this level not have space to store equipment? Why hide things here?"

Lu Pingxi said: "This requires further investigation. With Tina's personal belongings, I can use the tracking formation. Just wait a moment while I set up the formation."

Su Yu: "."

I've waited several times.

Soon, Lu Pingxi completed the formation, and then, a blue aura suddenly appeared, but this time, the blue aura turned into a blue arrow and pointed in a certain direction.

Su Yu was stunned when she saw this arrow. She said, "What kind of formation is this? Can it turn into an arrow? It's so humane!"

Lu Pingxi looked at the arrow and said, "Did you say this? This can be set, and it can also be changed into other shapes."

Su Yu asked: "Can I still set it up? Can I turn into a cat?"

Lu Pingxi nodded: "Okay."

As soon as he finished speaking, the blue arrow turned into a vivid blue kitten. The kitten jumped on the ground and was still licking its paws.

Su Yu's girlish heart suddenly softened: "So cute!"

Lu Pingxi gave the order: "Go."

The blue aura kitten immediately started running, followed closely by Lu Pingxi and Su Yu. They followed the blue kitten through the valley and then came to a rare plain.

They learned from the little flower demon that the underground in the fairy tower changes every ten floors. Below the tenth floor are mountains and ridges, and plains are rare.

This plain is unremarkable, but there are corpses of monster beasts lying on it. There are big pits everywhere. The smell of gunpowder smoke has not dissipated, and the ground is dyed red with blood.

This is a battlefield. There was a big battle yesterday or maybe just the day before yesterday. The human coalition should have won this battle, because no human corpses were seen on the battlefield, only the corpses of monsters lying here.

The blue civet cat didn't make any pause. It walked nimbly across the battlefield, while Lu Pingxi and Su Yu followed cautiously.

As they passed by, they observed the corpses of the monsters. These monsters were killed by giant firearms, and their bodies were full of big holes. Lu Pingxi checked and found that the monster crystals had been dug out. Come on, it seems that the human coalition also knows that the demon crystal is the most precious part of the demon beast.

Su Yu said: "The monsters are practicing in the fairy tower, and humans are developing technology in the outside world. The two sides are really struggling to compete. In the face of firearms, the monsters at the fifth level of Qi training will probably find it difficult."

Lu Pingxi remembered that the little flower demon was frightened out by his pack of explosives, and then said: "If it is more powerful, it might be able to threaten the foundation building stage."

In the foundation-building stage, you can live without grain and fetal breath, and live as long as a tortoise or a snake. It sounds very powerful, but without the protection of a magic weapon, the physical body cannot bear a single cannonball.

Only by reaching the golden elixir stage, where the essence is condensed and the body and spirit are unified, can the body be able to withstand firearms, but it will never be able to withstand such terrifying weapons as intercontinental missiles and nuclear bombs.

For today's humans, it is not difficult to transport a nuclear warhead into the Immortal Tower.

Thinking like this, they had followed the blue civet for dozens of kilometers. They walked for about an hour before stopping. The reason why they stopped was because they heard the fierce gunfire from ahead. .

Su Yu asked: "This is..."

Lu Pingxi said: "We are at the front line. The front should be the battlefield between the coalition forces and the monsters."

The blue aura cats are still moving forward, and it seems that their target is in that battlefield.

Su Yu asked: "What should we do now?"
