Lu Jun went to the dean's office while thinking about the words exchanged with Professor Yuan.

He could sense the other party's wealth of knowledge, so he proposed his own 'water breath'...... That is, using the principle of tides, the waves rich in high concentrations of water elements wash over the body, allowing the magic energy to penetrate into the flesh and blood and viscera, and slowly strengthen.

This is actually the same as the reason that when the realm breaks through, the expansion of the nebula leads to the majestic demonic energy that attracts the body and increases the strength.

Promoted to a super-level mage, it is said that he can tear apart slave-level demons with his bare hands.

Before, Lu Jun wanted to turn this passivity into an active and find a way, since the spiritual realm will increase with the improvement of cultivation, and the same is true for qi and blood, is there a division of qi and blood in the nine realms?

Professor Yuan regretted that this idea is difficult to put into practice, and some people have proposed it in the past, but the principle of realm breakthrough is not as simple as imagined, and it may be the sublimation of the life level, which is accompanied by all-round strengthening.

However, he was also sure that Lu Jun's tidal spirit seed phenomenon was very special, an isolated case, and worth studying, but he would have to wait until he finished dealing with the experimental project at hand before discussing it in detail.

Magical research is to find lonely cases from the cardinal number, and then study the solitary cases, summarize them, and generalize them to the cardinal number.

Lu Jun felt that it made sense, but he was quite strange when he left Professor Qianyuan's fiery gaze, as if he was looking at a precious test subject, so he slipped away first.

After a while, Lu Jun came back to his senses and arrived at the ground, Dean Xiao's office.

He pushed open the door with anticipation, and the mid-grade gold metal had been searching, and the major laboratories were not satisfactory.

Sister Lu Mei is also using her connections, her high school best friend at Demon Capital University, but unfortunately in that laboratory, only one kind of ordinary metal [Meteorite Shock Gold] was studied.

Now, Lu Jun's gold system will eventually return to the status of the big brother, and the higher level of the battle will be higher, especially before the Yangtze River experience is about to begin, one more hole card will improve the safety guarantee.

Dean Xiao sat in front of his desk, with a few boxes on the table, and gently gestured, "The special metals you want, each of them can be used to refine the precious materials of the best high-grade demon slaying tools." ”

Hearing this, he was delighted, that is, now that the gold system has not appeared, the world is only his first share, and the relevant resources are extremely overflowing, so the academy can collect the resources it needs so easily.

To be honest, many mages are more accustomed to using local materials and refining materials for hunting demons, making it easier to control the effect.

Metal-based materials, even if they are the best, have a lot of surplus when they are used in a narrow way.

Lu Jun leaned in front of him, opened a few boxes, and saw a pile of shining metal, each piece of metal was either as light as a feather or as heavy as Mount Tai, all of which contained majestic magical energy.

He was dazzled, and each piece was picked up and weighed, the platinum nebula in the spiritual world resonated, and the central sword seal was ready to move.

I really can't find a better fit.

Lu Jun couldn't help but say tentatively: "Dean Xiao, why don't you recommend one to me?" ”

"You kid." Dean Xiao shook his head and introduced them one by one: "The silver levitation of this metal is called [Flying Feather Gold], mixed with space system magic energy, refining into a magic slaying tool is most likely a powerful killing of the space tear type, which meets the requirements of Ling, and the texture of the hand is also very light." ”

"The gray and transparent piece is called [Empty Ming Copper], with chaos magic energy, refining into a magic slaying tool with a strange effect, which can ignore most of the elemental shield defenses such as the Water Emperor, the Water Flower Sky Canopy, the Barrier, and the Light Blessing."

The two metals that Dean Xiao pointed out at random, Lu Jun was short of breath, the characteristics of the two special metals were very powerful, and the refining power of the gold system was definitely greatly improved.

Especially the latter, he had a little impression that in this battle of the national capital, a certain destruction mage of the German team had a similar talent, ignoring the destruction of elemental defense, and ranked third on the list of destruction mages of the national palace, while Mo Fan was only fifth, which was not strong.

As long as Lu Jun refines this empty copper, the lower limit of the gold system is guaranteed to this extent.

Finally, Dean Xiao pointed out a piece of black and heavy steel, and his expression hesitated slightly.

The surface of this heavy black gold naturally spreads some textures, the curves are sinuous and vigorous, and a certain majestic and supreme aura overflows.

Lu Jun had noticed that this metal was not simple, it actually had a faint spiritual coercion, and it was full of evil qi and indifferent to the killing aura of life, which was very close to the killing positioning of the alloy system.

"[Dragon Pattern Dark Iron], the exclusive metal of the ancestral family, contains mysterious power, and the formation conditions are extremely harsh, there must be the underworld where the true dragon fell and buried, brewed over the years, and the unknown and cursed precipitation can be derived from the metal veins."

Dean Xiao paused and said: "After excavation, it will be processed and purified by special smelting technology, and the value is definitely the highest among these metals. ”

"The only drawback is that the specific effect cannot be controlled, and the range can only be confirmed, which belongs to the lethal type, but the lower limit guarantee will not be worse than the other two."

Hearing this, Lu Jun knew that it was a directional blind box.

"Personally, I recommend you pick this one." Dean Xiao revealed: "The ancestral family's bloodline is not simple, this metal smelting technology originated from the pre-Qin period, and it may be out of print, and it is suspected that the first emperor of the Qin State refined the leftovers of the magic tool [Tai'a Sword]. ”

Lu Jun understood it at once, and used his power for personal gain, and took extra care.

And the quality of the dragon pattern dark iron is really good, hard and heavy, and the dark luster is in the same vein as the meteorite shock gold.

Metal materials are only one aspect, and when they are integrated into the Zhenjin Sword, they will be baptized and sublimated by the gold nebula, and they will be permanently consolidated into a powerful effect, similar to Zhenjin, the original super-level fire energy melts, and now it is slowly growing, and even the monarch level cannot be broken.

Dean Xiao nodded with satisfaction when he saw that Lu Jun had made a clever choice.

He is optimistic about this student, if he has something to do in the main campus for a period of time, he plans to accept him as a closed disciple, and pass on his body of water magic, which is enough to close his eyes under the yellow spring.

Lu Jun sincerely thanked him: "Thank you, Dean Xiao. ”

"The Academy is proud of you." Dean Xiao stopped and said, "Go back and practice hard and strive to give back to the society." ”

Saying goodbye to the other party, Lu Jun couldn't wait to go home to refine.

In Jinyuan's apartment, Lu Mei was immersed in cultivation, and there were signs of not going out of the constellation, and she didn't even pay attention to her younger brother living in school for several days.

He didn't bother his sister, he controlled the stars, the platinum nebula of the spiritual world, a black sword mark rushed out, manifested in reality, and shrunk to a normal size, more than three feet.

The sword light went straight into a piece of dragon-patterned iron the size of a human head in the box, and a "sonorous" sound sounded softly.

Immediately afterwards, the platinum lines on the surface of the Zhenjin Flying Sword spread, and the dragon pattern dark iron slowly melted, forming a cloud of black deep metal, which merged into the natal magic tool.

The whole pitch-black divine sword has been transformed, and the dragon-shaped pattern climbs up from the tip of the sword, like a real dragon winding, encapsulated in black gold, like a fine dragon scales clearly visible, and thousands of wisps of platinum glow overflow between the gaps in the scales, forming a road mark, and the two reflect each other.
