In the back mountain, at Dugu Nianxue Cave Mansion, two figures landed on the grass in the backyard.
Dugu Nianxue had already restrained her strong aura at this moment, and looked at the scars all over Han Feng's body again.
After just a quick glance, Dugu Nianxue's eyes turned cold and she said in a cold voice.
"With a mere Chen-level four-star cultivation level, you dare to show off your ambitions in the ring with some meager means. Do you really think you can't die?"
Although Dugu Nianxue's voice was cold and her tone was very unkind, Han Feng could feel a hint of concern in the cold words.
He couldn't help but feel warm in his heart and responded with a wry smile.
"What the instructor taught me was that the disciples were too reckless and made the instructor worried."
Dugu Nianxue snorted coldly.
"Humph, I'm not worried about you, I'm just reminding you, don't overestimate your capabilities in the future and lose your life in vain!"
Han Feng knew in his heart that this mentor was a cold-faced and warm-hearted person who refused to admit that he cared about him, so he refused to point it out and nodded quickly.
"What the instructor said is true, and the disciple just needs to obey his orders!"
Seeing Han Feng's obedient attitude, Dugu Nianxue's cold expression softened slightly and she asked casually.
"How's your injury?"
Han Feng hurriedly replied: "The vice president has given the disciple a "Fifth Grade Healing Pill". The injury is now stable and it only takes a few days to recover."
Dugu Nianxue nodded slightly and said with a slight hesitation.
"The fifth-grade elixir has strong medicinal power. In your current state, you cannot refine the medicinal power at all, and you will only waste this elixir.
Forget it, you come with me and I will help you refine this elixir. "
After that, Dugu Nianxue walked directly towards the cave.
When Han Feng heard this, he was stunned for a moment.
After confirming that he heard correctly, Master Dugu really wanted to help him refine the elixir, he followed him in a hurry.
Han Feng followed Master Dugu all the way to a secret room in the cave.
The secret room is spacious and transparent, with a "practice room" and a "living room" inside.
The two came to the practice room. Dugu Nianxue stepped back, sealed the secret room, and asked Han Feng to sit cross-legged on a futon, and she sat cross-legged opposite him.
Immediately, Dugu Nianxue raised her palm and fired a hot palm force from the air, penetrating into Han Feng's dantian.
Using powerful skills, he accelerated the refining of the fifth-grade elixir in Han Feng's body.
At this moment, Han Feng only felt a pure, soft and warm energy, centered on his dantian, spreading in all directions like a tide.
Every time the energy spreads, his severely injured body will recover a little, and the already exhausted spiritual power and blood are also rapidly recovering.
The power of this fifth-grade elixir is indeed beyond my imagination!
Secretly amazed for a while, Han Feng subconsciously opened his eyes and looked at Dugu Nianxue while running his exercises to heal his injuries, but he happened to meet the other person's cold and calm eyes.
The two of them were sitting opposite each other, only a few feet away from each other.
When their eyes met, the two of them were slightly startled, and then looked away at the same time.
Han Feng inexplicably felt that his heartbeat was accelerating, and he couldn't help but secretly thought.
"What's going on? Is my resistance to beautiful women reduced? Or is Teacher Dugu's gaze too lethal?"
Han Feng was in awe of Master Dugu and did not dare to think too much. He quickly calmed down and collected his mind.
There was silence in the practice room for a moment, and the atmosphere returned to normal. Only then did Dugu Nianxue take the initiative to speak.
"How did you defeat that Tianyuan Academy disciple who understood the element of thunder and lightning today?"
Hearing that Dugu Nianxue asked about this matter, Han Feng couldn't help but be stunned.
"Teacher, did you also see my fight with him?"
Dugu Nianxue nodded while refining the medicine for Han Feng.
"Well, I was already here before you and him took action, but I just didn't show up."
It turned out that Dugu Nianxue arrived a little earlier than Han Feng imagined.
She just kept hiding in the dark and did not show up. At the same time, she was also secretly ready to take action at any time to save Han Feng.
Seeing that Dugu Nianxue was curious about this matter, Han Feng did not hide too much.
"Teacher, it's actually very simple. I just used the principle of "object conduction" to guide the lightning to himself."
Han Feng immediately explained the principle and tried to make it as easy to understand as possible.
Although the Lingwu Continent is prosperous in terms of military force, and strong men can even fly to the sky and escape from the earth, move mountains and fill the sea, it obviously does not know much about some ordinary scientific knowledge.
Han Feng defeated Fang Xuan today just by using a simple physical principle.
"You said both "water and metal" conduct electricity?"
After listening to Han Feng's explanation, Dugu Nianxue's eyes flashed slightly, but she raised her own doubts.
"Metals can conduct the power of thunder and lightning. I know a little bit about it. In nature, when lightning strikes rivers and lakes, the power of thunder and lightning seems to be able to be transmitted in the water.
But why do I find that the water condensed by ordinary spiritual warriors using water-based energy cannot conduct electricity? "
Han Feng was stunned when he heard this. He didn't expect Dugu Nianxue to ask such a question.
Xuan Ji also explained seriously.
"Because 'pure water' cannot conduct electricity, and the water in rivers and lakes contains many impurities. These impurities melt into the water to form a complex state, through which lightning can be conducted."
Dugu Nianxue listened to Han Feng and recounted knowledge that was completely out of this world.
The light of wisdom shone in those clear and deep beautiful eyes, and she seemed to understand.
"I see."
Dugu Nianxue nodded, but asked again.
"Then since both metal and water can conduct electricity, and you also came into contact with the sword blade, why was he electrocuted but you were unscathed?"
"Well……"
When Han Feng heard this, he was a little surprised for a moment. He didn't expect that Dugu Nianxue had such careful thinking and once again grasped the key to the problem.
Han Feng was thinking about how to explain to him the principle of "closed loop" in physics.
Unexpectedly, Dugu Nianxue's eyes flashed with wisdom, and she guessed.
"Could it be because of the principle of "circulation"? Thunder, sword, water flow and the man's body formed a subtle cycle.
But you are outside the cycle, and energy cannot flow, so you are not harmed. "
"I……"
After listening to Dugu Nianxue's analysis, Han Feng was stunned.
If he hadn't been recovering from his injuries at this moment, he would have jumped up in shock.
Han Feng stared at Dugu Nianxue at this moment, his eyes became very strange, and he was even suspicious.
Could the other party also come from modern society? This idea is too advanced.
She actually used the theory of spiritual warriors to explain scientific phenomena in past lives!
Han Feng estimated that if Dugu Nianxue had really been born in his time, with his wisdom and understanding, he might have become an academician of the National Academy of Sciences in the future.
Is this what the legend says, if you learn mathematics, physics and chemistry well, you will not be afraid of traveling around the universe?
Thinking about his disastrous "mathematics, physics and chemistry" results and Dugu Nianxue's talent of being a self-taught person, Han Feng couldn't help but feel a little bitter.
No wonder they are all moon-level warriors, but I am still a Chen-level spiritual warrior. This is the gap.
Looking at Han Feng's complicated and changing expression, Dugu Nianxue hesitated slightly.
"What, did I say something wrong?"
Han Feng smiled bitterly: "No, no... what you said, instructor, is basically the standard answer."
Hearing this, Dugu Nianxue showed a slight smile on her face, but immediately expressed her appreciation.
"Han Feng, compared to your talent in cultivation, your wisdom and knowledge are more amazing. Even I am inferior to you!"
After receiving praise from "Dugu Xueba", Han Feng suddenly had the urge to cover his face and burrow into the ground, committing suicide in shame and anger, but in the end he could only nod with a wry smile.
"Uh...it's okay...everyone is with each other, each other."
While the two of them continued to exercise and heal their injuries, Dugu Nianxue suddenly asked about something again.
"By the way, why didn't you agree to be Murong Shu's disciple today?"
Han Feng is still immersed in the "frustration" of being a modern person in a different world and being crushed by people using scientific knowledge.
Suddenly I heard Dugu Nianxue ask about this matter, and without thinking for a moment, I subconsciously responded.
"Because this person's heart is evil and he has done something wrong to you, mentor..."
Halfway through his words, Han Feng realized that he had let something slip and quickly stopped.
Opposite her, Dugu Nianxue's beautiful face was slightly stunned at this moment, her beautiful eyes staring at Han Feng.
"What did you say……?"
