In order to better trade items, we naturally need to grade items.

The boss said: "Yes, we now call props made from materials outside the immortal tower a mortal weapon, and props made from materials inside the immortal tower a spiritual weapon. You may not know that spiritual weapons made from spiritual materials are very powerful. Even a cold weapon has the same lethality as a hunting cannon. After all, hunting cannons need to be loaded, but spiritual weapons can be used all the time!"

The little flower demon sent a message in confusion: "Do you humans have such strong hands-on ability? You don't even have a cultivator, so you just tinker with the spiritual weapon?"

Lu Pingxi asked: "How were these spiritual weapons made?"

The boss said: "That's more important than that, of course, it's a mechanic factory, using robotic arms, melting them with ultra-high temperatures, and then making them into new weapons. You probably don't know that the United Army discovered an iron ore cave on the third floor. The iron inside is all spiritual iron. The hardness, flexibility and lethality of weapons made of spiritual iron are crushed by ordinary iron."

Lu Pingxi asked: "Can monster bones be used to create weapons?"

The boss said: "Of course, and the weapons made of monster bones are even more powerful. Perhaps the monster bones still have the evil spirits of the monsters before they exist in the monster bones. In short, the monster bone weapons can cause some damage to the monster's souls."

The little flower demon sent a voice transmission: "Of course, the monster bones are nourished by spiritual energy over the years with the practice of monsters, and naturally have stronger attack power. But I am quite curious, why can mortals make monster bones into weapons? Is there any cultivator among you humans?"

The boss couldn't hear the voice of the little flower demon, so Lu Pingxi asked: "How is the monster bone used to build weapons?"

The boss replied: "That's more important than saying, of course it's still a mechanized factory. No matter how hard the bones of this monster are, can they be harder than lasers? Can they withstand super high temperatures? Can they withstand the polishing of mechanical diamond files day by day?"

Lu Pingxi understood that the power of technology is not weaker than the power of cultivating immortals at all. Now that the combination of the two has led to the rapid growth of human strength.

A long time ago, someone said that nuclear bombs are like rocket launchers in the hands of children to humans, and they will even finish playing with themselves if they are accidentally done.

This shows that the human body is too fragile, while the weapon invented is terriblely strong. But now, with the tower of immortal cultivation, the shortcomings of human body fragility may be completed. In that case, human beings really have no weaknesses.

Lu Pingxi exchanged most of the wild beast materials obtained from the second floor, and then purchased three hunting cannons and thirty hunting shells. The shells were as big as a bottle of mineral water bottles, and looked like bullets. The shells had a trigger device and would explode when they collided at high speed.

Lu Pingxi exchanged a lot of wild beast materials, and after purchasing the weapons, there was still some leftovers. Lu Pingxi gave the boss an account and asked him to transfer it directly to his account.

The boss was secretly happy. He knew that these materials would become more and more valuable in the future, and it was the most cost-effective transaction to exchange them for money.

Afterwards, Lu Pingxi tied three hunting cannons to the level 10 bag, then walked out of the store, and pedestrians on the road looked at him.

Carrying a level ten bag was already attractive enough, but Lu Pingxi carried three more hunting cannons, but gradually, everyone's eyes became cautious again, because the weight of the three hunting cannons alone cannot be ignored, let alone the huge level ten bag, but this person carries so easily, which is enough to show that this person is a veteran!

Only those who come to the Tower of Immortal Cultivation very early and are nourished by spiritual energy can have such strong physical fitness. Everyone is even sure that this is a ruthless person who has returned from the third floor.

In the tower of Immortal Cultivation, the higher the spiritual energy, the higher the degree of strengthening the human body. Why did the United Army build defensive fortifications at the entrance of the fourth floor in any case? The purpose is to make the fourth floor rich spiritual energy.

So everyone regards Lu Pingxi as a veteran who returns from the third floor, but in fact they are not wrong. Lu Pingxi is indeed a veteran. After all, his world's top adventurers and the first adventurers to reach the Tower of Immortal Cultivation. He and Bei Ye and De Ye and other men at the top of the food chain have cooperated.

He also challenged several of the most dangerous areas in the world with some adventurers who like to commit suicide.

But ordinary people and ordinary adventurers don't know him.

After Lu Pingxi bought weapons, he went to buy food, medicine and other supplies. When buying these supplies, the little flower demon did not talk much because she was also very greedy.

Human food is delicious even a bag of compressed biscuits. She feels that during the time she has followed Lu Pingxi, she is the happiest time to eat!

After Lu Pingxi purchased the materials, he went to the email office of Xiuxian Town and sent an email out.

The little flower demon asked, "What are you doing? Send a letter to your loved ones?"

Lu Pingxi said calmly: "Didn't you tell you that I am an orphan? I'm sending letters to my three assistants. I don't know if they are willing to cooperate with me."

The little flower demon asked knowingly: "Why are you unwilling to cooperate with you?"

Lu Pingxi touched his chin and said while thinking: "Maybe I am too calm and I have to think twice before doing anything. My assistants are too young and a little impatient, and are not very adaptable to my rhythm."

Little Flower Demon: "..."

Do you have a big rhythm?

The little flower demon can already imagine why these three assistants are unwilling to cooperate with Lu Pingxi.

The so-called mailing is just sending an email using the computer from the email office. After completing it, Lu Pingxi went to the streets again.

The little flower demon asked impatiently: "Are you still going to the third floor?"

Lu Pingxi said: "Don't panic, let me think about what else is not prepared for."

Lu Ping thought while walking west, but as he walked, he saw a strange shop. The name of the shop was: "Creative Workshop".

Lu Pingxi was a little curious, what kind of store is this?

He observed the door for a while, and then walked in after confirming that there was no strange trap. As soon as he walked in, Lu Pingxi saw a young man lying on a chair. The young man was wearing a black vest with some stains on the vest. He wrapped his hair in a towel and his hands were wearing thick gloves.

There is a big hammer on one side of the chair, and the hammer actually emits spiritual energy, which is enough to show that this is a spiritual hammer made of spiritual iron.

When the young man saw Lu Pingxi walking in, he immediately stood up: "Customer, come and take a look, I have all been creative props, many of which are made of second-layer beast bones, and the quality is absolutely guaranteed."
