That night, Lu Zheng walked out of the room, and with a thought, the cold ice sword flew out of the center of his eyebrows, and instantly turned into a giant sword ten times the size.

One step at a time, stepping on the sword, and the next moment, the ice sword carried Lu Zheng into the sky and disappeared into the night.

For the first time, Lu Zheng was a little uncomfortable, but he was more excited, and after gradually getting used to it, the speed of Edgeworth also accelerated.

In less than half an hour, he came to the sky above the mountain wall where the treasure was stored, but what made him frown was that the boulder outside the mountain wall had been removed, and a group of people were moving wooden boxes from the cave to the outside.

Tiger's mouth!

Seeing this, Lu Zheng's face instantly turned cold, and he listened carefully, and occasionally heard a few words of Japanese language floating out of the mouths of the group of people who moved the wooden boxes.

"Wa people!"

Lu Zheng's face became even colder, if the Chinese people found this treasure, he might give them some benefits to send them away, but since they were from the Japanese country, they could only hehe.

With a thought in his mind, Lu Zheng put away his flying sword, fell from the sky, and landed in front of the mountain wall.

Seeing Lu Zheng descending from the sky, a group of Japanese people were startled and shouted, "Who is it?"

"Humph!"

Lu Zheng let out a cold snort, and with a wave of his hand, dozens of qi bursts shot out, instantly knocking out all the Japanese people outside the cave.

Casually putting the wooden boxes stacked outside the cave and the wooden boxes that were being carried into the storage ring, Lu Zheng strode towards the cave, and casually knocked out a few Japanese porters along the way, and he had already come to the storage room.

However, outside the storage room, there were four U warriors, and when they saw Lu Zheng, the four U warriors instantly changed color, and one of them shouted in Chinese: "It's not good, a Chinese man broke in, kill him quickly!"

As soon as the words fell, the other party pulled out the katana at his waist, held the knife in both hands, rushed towards Lu Zheng quickly, and slashed at his neck.

"Look for death!"

Lu Zheng snapped out a little qi with his fingers, and the poofing sound directly pierced the opponent's eyebrows.

"He is a master of ancient martial arts, let's go together!"

Seeing this, the other three warriors drew their swords one after another and rushed towards Lu Zheng together.

Lu Zheng smiled disdainfully, and once again bent his fingers and popped out three points of energy, sending the three warriors to hell.

"Bang!"

A gunshot rang out, but the bullet did not hit Lu Zheng, but was caught between his middle finger and index finger.

"This, how could he possibly hold a bullet between his fingers?"

Jiro Fujita, who fired the shot, stared at Lu Zheng with a dull expression, his eyes full of disbelief.

"Smack!"

As soon as Lu Zheng's fingers loosened, the bullet slipped from between his fingers and fell to the ground, while his gaze fell on Fujita Jiro's face.

"How do you know here?" As he spoke, Lu Zheng walked towards Jiro Fujita.

"No, don't come here! or I'll shoot!" shouted Fujita Jiro, his face turning to horror.

"Can you shoot?" Lu Zheng laughed playfully, but his pace did not stop.

"Bang bang bang!"

Fujita Jiro frantically pulled the trigger and didn't stop until the magazine was empty, but to his horror, the man who was as powerful as the devil was gone.

"One last time, who are you and how did you find here?"

Before Jiro Fujita could rejoice, the devil's voice sounded behind him, causing him to run out of the cave with a scream.

"Whoosh!"

The figure flickered, and the devil blocked his way again.

"Don't kill me, I'll say anything!" Fujita Jiro was about to break down, telling everything he knew like pouring beans.

It turns out that this Fujita Jiro is the son of Fujita Nakaji.

When Fujita Nakaji came to China to hunt for treasures, he left a letter for his son.

As a result, the treasure was not found, but clashed with Lu Zheng and was made an idiot by Lu Zheng.

Because Fujita Nakaharu is a foreigner, after the hotel found out that he had become an idiot, it called the police, and the police contacted Fujita Jiro through investigation.

Fujita Jiro soon came to Tu County, and took his father, who had become an idiot, back to Wakoku for treatment, and after several months of treatment without seeing results, by chance he saw a letter left by Fujita Nakaji, and knew that there was a huge treasure hidden in Tu County.

Therefore, he immediately formed a team and began to go to Tu County to investigate, and finally locked the approximate location of the treasure in a week, and successfully found the treasure today, and was about to move the treasure out and transport it back to the Wa Kingdom, but Lu Zheng came.

I have to say that things are really coincidental to the extreme, if Lu Zheng had arrived a few days late, the treasure would have been emptied long ago.

After learning the ins and outs of the matter, Lu Zheng did not kill him, but only made him an idiot, following in the footsteps of his father Fujita Nakaji.

After putting all the treasures into the storage ring, Lu Zheng returned to the Medical Immortal Gate with the sword.

It's been less than an hour since it came and went, and that's the benefit of Edgeworth's flight.

Entering the Divine Domain again, Lu Zheng took out the boxes containing gold bricks and silver winter melons, 200 boxes of gold bricks totaling 4,000kg, and 600 boxes of silver winter melons totaling 60,000kg.

According to the records of the refining exercises, 100 grams of gold can refine about 1 gram of gold essence.

The same is true of silver.

In other words, Lu Zheng can finally get about 40 kilograms of gold essence and 600 kilograms of silver essence.

The ratio of refining a gold and silver sword is 10 kilograms of gold essence and 100 kilograms of silver essence, that is to say, this gold and silver worth 1.5 billion can only refine four first-grade magic weapons, so that the material cost of a gold and silver sword needs more than 300 million.

If you don't have money and want to play Xiuxian, you really can't play it.

After a little emotion, Lu Zheng summoned his ball of transparent true fire, the real fire was only the size of a fist, and it didn't seem to have any temperature, but after touching a gold brick, it was only a few seconds before refining it into a granular gold essence.

After refining the gold and silver into gold essence and silver essence respectively, Lu Zheng prepared the refining weapon.

The first step is to melt the material.

Throwing an appropriate amount of gold essence and silver essence into the real fire and calcining for a few minutes, the two materials turned into a puddle of golden liquid and a puddle of silver liquid, respectively.

The second step is to refine impurities.

With the thought of moving, the temperature of the real fire rose again, and with the calcination, layers of bubbles emerged from the two pools of liquid, and at the same time, a layer of black substance appeared on the surface, which was the impurities in the material.

After removing the impurities, Lu Zheng manipulated the two pools of liquid to fuse with each other, and gradually lowered the temperature after the fusion.

As the temperature dropped, a small sword one foot long with a faint golden color gradually took shape.

Among the four steps of refining, the last step is the most difficult to depict the formation.

Once the formation cannot be integrated with the body, it will cause the refining to fail.

The gold and silver sword is the simplest magic weapon, and it only needs to be carved into two formations, one is the Breaking Formation and the other is the Spirit Gathering Array.

Lu Zheng had practiced these two formations countless times, but at the last moment, he was still a little nervous.

Taking a deep breath, his eyes stared at the sword embryo tightly, and at the same time, his hands kept flying, constantly hitting the true yuan, and carving the formation on the sword body.

Break the battle!

Gathering Spirits!

"Boom!"

Two milky white spiritual lights bloomed from the sword, and Lu Zheng finally breathed a sigh of relief, he knew that the two formations had been successfully depicted.

The temperature of the real fire rises again, and after half a moment, it suddenly drops again.

After rotating several times like this, both formations were deeply imprinted into the sword body.

Flameout!

As soon as Lu Zheng's mind moved, the true fire retracted into his dantian.

After some investigation, this refining weapon actually consumed fifty percent of his true yuan, of course, this is mainly because he is not very skilled in refining weapons for the first time.

As the saying goes, once raw and twice cooked, after using the spirit stone to restore the true yuan, Lu Zheng began to refine the second gold and silver sword.

Maybe he really had the blessing of the god of luck, and the next three refining weapons allowed him to successfully refine the gold and silver sword.

After refining the weapon four times, he had a little more understanding of the refining weapon, and he wanted to continue refining a few more gold and silver swords, but unfortunately there were no extra materials.

After leaving the customs, Lu Zheng summoned the land Ye Miaoge, the servant Yang Ping, and Hou Junfei and gave them a gold and silver sword respectively.

And gave Hou Junfei an order to vigorously collect gold and silver.

There are also levels of refiners, from low to high, which are five levels: human level, earth level, heaven level, grandmaster, and great grandmaster.

For the first time like Lu Zheng, who is in contact with refiners, he is not even a human-level refiner, so he needs a lot of materials to brush up on his proficiency, and it is best to reach a human-level refiner.

Of course, in addition to asking Hou Junfei to collect gold and silver with all his might, he also drew an atlas of ores and special wood for him, and asked him to collect according to the pictures on it.

The atlas he gave was all the various materials needed to refine a first-grade magic weapon.

Time always passes inadvertently, and before you know it, the college entrance examination is coming.

Lu Zheng had already decided to go to the First University, but in order not to disappoint the head teacher Gao Hongjun, he still answered the questions with all his might.

After the college entrance examination, Lu Zheng summoned the high-level officials of the Medical Immortal Sect and made arrangements, and took Gu Xin to Yanjing.

In two months, he will report to the First University, which means that he will be separated from Gu Xin, so he wants to take advantage of these two months to accompany Gu Xin, Elena and Jessica.

Two months passed in a flash, it was time for Lu Zheng to report to the first university, and he was the most reluctant to part, looking at Gu Xin, who was crying, Lu Zheng took her into his arms and comforted her softly.

After some comfort and promise to talk to her in a week, Lu Zheng stepped on a special plane and flew to the mysterious First University.

The First University was neither founded in the capital nor in the city, but in a primeval forest.

Before he could register, Lu Zheng received a detailed introduction to First University.

First of all, students who want to become the number one university must take an entrance examination before enrolling. Those who pass the assessment will receive a J2 liquid rewarded by the state, and get a chance to develop their potential and strengthen their physique.

Then, ten days before the start of the semester, the university will send them to the outside of the primeval forest, and give them a rough map, as well as a day's food and water, so that they can go to the First University in three days through the primeval forest of more than 500 miles.

If you can't reach the first university within three days, you will be disqualified from this year's admission and wait for the test next year, and if you fail to meet the requirements for three consecutive times, you will never have the opportunity to enter the first university again.

After becoming a student of the first university, you will go through a week of Guwu enlightenment, and you will officially enter the school after a week.

In other words, this year's freshmen of First University have already arrived at First University a week ago, while Lu Zheng only arrived today and completely skipped the previous steps.
