Lu Hong left the school, and then quickly ran towards the most dilapidated slum in the Qingtian Federation where he lived.

Surrounded by towering skyscrapers, the lowest of which has reached 200 floors, the use of reinforcement charms and special materials in the scientific and technological civilization can make the skyscrapers reach the sky, and the use of lightning protection charms and buoyancy charms can make the building more stable and safe.

The speed of the elevator is also more than twice the speed of sound, and the person will not have any discomfort.

This is the incredible building under the Xiuzhen civilization, and Lu Hong lives in the oldest building near the dumping of mechanical waste, and there is no reinforcement of the rune array at all, so this place is also known as the most dilapidated slum area of the superstar.

But fortunately, Lu Hong doesn't care about the quality of living at all, what he cares about is learning more things from Li Lao.

Li Lao also lives in the slums, but unlike Lu Hong, Li Lao definitely does not mean that he can't afford to buy a house, and it seems that he also has his own reasons.

The acquaintance between the two is also very interesting, by chance, Lu Hong saw the scene of Li Lao assembling the magic weapon, and was immediately fascinated by the dazzling skills, Li Lao also thought Lu Hong was interesting, so he came up with some small questions to test Lu Hong, and repaired an old crystal brain damaged by the rune array, Lu Hong miraculously repaired the transistor of the rune array with his intuition, Li Lao was very surprised, and agreed to teach Lu Hong to repair the machinery and magic weapon.

Machinery and magic weapons are very different, since the era of overhaul, the role of magic weapons has become more and more prominent, and various types of magic weapons have emerged, no longer limited to flying swords, etc., but also include various magic weapons, firearms, civilian spaceships, and so on.

The biggest difference between the magic weapon and the machine is that the magic weapon must be equipped with a core magic circle, and combined with various types of rune arrays, the magic weapon is formed.

The core of the magic weapon is the formation, and the way of the formation is extremely difficult. Lu Hong vaguely understood that something seemed to have happened 50,000 years ago, which led to the arrival of the era of the Great Repair Truth, which was the heyday of the formation before the Great Repair Era, and the demise of that era directly led to the loss of most of the powerful formations, and the current formation has not been handed down to one-third of that period, and it is incomplete, resulting in the formation is extremely precious, and the refiners who have the ability to form are becoming more and more rare.

In contrast, machinery is much simpler, and it only needs to work on the mechanical structure, plus a variety of transformers composed of various functions, to be able to make a variety of functional machinery.

It's just that in the minds of cultivators, the role of machinery is very different from that of magic weapons.

Finally came to Li Lao's dilapidated mechanical repair shop, although it was a mechanical cultivation shop, Lu Hong knew that Li Lao was at least a bluestone-level refiner.

According to the strength of their own refining magic weapons, the refiners are divided into: bluestone, red copper, silver, yuanjing, and pinnacle five levels, and the corresponding cultivation realm is the four realms of qi training, foundation building, golden pill, yuan infant, and transformation god.

Because of the lack of formations and the degree of development of civilization in the Great Cultivation Era, there are extremely few cultivators at the Yuan Infant level, so the magic weapons with terrifying power at the Yuan Crystal level are also extremely rare. As for the cultivators of the Transformation Stage realm and the peak-level magic weapons, some people even doubted whether they really existed.

"Teacher, I'm here!" Lu Hong shouted loudly, completely different from the constant distraction in school.

For refining, Lu Hong has a very unusual enthusiasm, especially when he saw that Old Man Li once engraved the core magic circle of a magic weapon with his own hands, Lu Hong felt that this mysterious Old Man Li was unfathomable.

"Well, the customer wants to repair a 13th-generation crystal brain produced by the Chiyan Sect, you can disassemble and decorate it yourself!" Old Li seemed to be busy with something, and said to Lu Hong without raising his head.

Lu Hong nodded, rolled up the sleeves of his shabby school uniform, picked up the precision equipment and began to disassemble his valuable crystal brain.

The crystal brain is a kind of machinery, although the function of his psionic bracelet is not comparable to this crystal brain, but the magic weapon is a magic weapon after all, and Lu Hong regards it as a treasure, which is a gift from Old Man Li to himself.

As soon as he has time, he can also study the core magic circle on the psionic bracelet, if he really understands it, then Lu Hong will not be ignorant of magic weapons.

Skillfully disassembling the incomparably precise parts of the crystal brain, and suspending each enlarged part of the crystal brain on a light curtain in front of him, Lu Hong carefully disassembled it, looking for possible faults.

Eventually, he discovered that there was a problem with a discontinued part, and that a transistor had burned out in the cooling array next to the part.

Lu Hong first replaced the rune array transistor to test that the rune array could work, and then looked up and asked Old Man Li: "Teacher, are there any I-26 model parts produced by the Chiyan Sect twenty years ago?" ”

Li Lao shook his head and said: "It's too old, this Chiyan faction, the crystal brain designed by the Red Yan faction actually uses parts that have been discontinued, so that the computer can basically only be replaced if it is broken, and users have a high probability of buying their crystal brain, after all, the crystal brain at this price on the market is monopolized by the Red Yan faction." ”

Chiyan No. 2 Middle School, which was affiliated to the Chiyan faction, was also the high school where Lu Hong was located, and Lu Hong said indifferently: "I'll go to the magic weapon tomb to find it." ”

Li Lao nodded lightly and said, "Be careful, although you kid is a monster, danger in this world always appears when you are most relaxed!" ”

Lu Hong nodded, glanced at the component design drawings on the computer, and rushed out of Old Man Li's mechanical repair shop, and rushed towards the magic weapon tomb not far from here.

It's a forgotten desolate place, and when you look up from the vast Superstar, you can see the pitch-black starry sky, but the dark Superstar is illuminated by the psionic lights that float all year round, just like the sun that only exists in memory.

In the sky, a blue planet is very big, and it is also very beautiful in Lu Hong's eyes, and he longs to return to the place where he once existed, the place called the earth, the holy land of cultivation in the era of great cultivation.

Lu Hong carefully checked all the surroundings of the magic treasure tomb, relying on his keen sense of smell, he felt that something was wrong around him.

"Bump!" A huge ring-shaped magic weapon fragment was knocked away by something, Lu Hong's eyes jumped suddenly, he didn't expect such bad luck to encounter a demon beast.

The demon beast is actually the original inhabitant of the superstar, but it is bloodthirsty and very brutal, this human-headed demon beast is called the Gold Swallowing Beast, which is a low-level demon beast that feeds on metal, no demon power, but the brute force is amazing, and a mouthful of beast teeth is extremely sharp, and it can be torn apart with a solid alloy, not to mention a human.

Lu Hong didn't dare to be bitten by this terrible demon beast, even if he was very confident in his body tempered as a magic weapon, he didn't dare to be bitten by the gold swallowing beast easily.

Suddenly, the gold-swallowing beast rushed towards Lu Hong, Lu Hong's eyes were as if he had completed countless repetitive movements, retreated, and jumped out of a step in one direction, this step was a terrifying seven or eight meters, this kind of physical strength, even the 5% of the spiritual root awakening guys couldn't do it.

The Gold Devouring Beast roared, biting a huge shaft-shaped alloy and smashing it towards Lu Hong.

There was no panic in Lu Hong's eyes, there was just endless darkness, which seemed to be able to swallow everything.

This time, Lu Hong did not retreat but advanced, dodging the huge iron rod, his body was like electricity, flashed to the flank of the demon beast, stretched out his fist, and the muscles on his arm were already green, at this moment, he roared violently: "Die!" ”

The punch smashed straight into the most vulnerable neck of the Gold Swallowing Beast, and with a crisp sound, the Gold Swallowing Beast wailed, feeling that the bones connected to its head had shattered.

Its eyes were full of violence, it didn't expect this weak human being in front of it to be so terrifying, its violence turned into madness, and its head slammed into Lu Hong's body, which was already a deathly counterattack.

"Bump!" With a muffled sound, Lu Hong's body ejected like a bullet, like an insignificant ant being catapulted into the mountain range where the magic weapon was stacked.

The Gold Swallowing Beast also slowly fell, it closed its eyes in relief, this blow, even a spirit root awakened 10% of the human could not be stopped, because it was a blow that burned its life.

Time passed slowly, and a minute later, Lu Hong came out of the magic weapon tomb in tatters, and a mouthful of metal chips spit out from his mouth, he felt the pain all over his body as if it were broken, but his body produced a warm current.

This is the power of [Alchemy], the existence of the legendary ability to temper immortal weapons, although he has no entry at all now, but the ability to withstand fighting makes Lu Hong feel mad.

After stretching his body for a while, making sure that there were no internal injuries and that his physical body was stronger, he was content to search for the crystal brain parts he needed everywhere in the magic weapon tomb, and finally found it very easily from under the body of the gold swallowing beast.

After completing everything, Lu Hong looked at the huge body of the Gold Swallowing Beast and showed some smiles.

The teeth of the Gold Swallowing Beast are very good hard objects that can be exchanged for money, and the flesh of the Gold Swallowing Beast is also greatly replenished, and it is also good to bring back some of the replenishment body yourself.
