In the back mountain, Dugu Nianxue Cave, two figures landed on the grass in the backyard.

Dugu Nianxue had restrained her strong aura at this moment, and her eyes looked at Han Feng's scars again.

Just a glance, Dugu Nianxue's eyes turned cold and she said with a cold voice.

"A mere Chen-level four-star cultivation level, relying on a little trick, dares to show off in the arena. Do you really think you can't die?"

Although Dugu Nianxue's voice was cold and her tone was very bad, Han Feng could feel the slightest concern in the other party's cold words.

He couldn't help but feel warm in his heart and responded with a wry smile.

"What the tutor taught is that the disciples are too reckless and worried the tutor."

Dugu Nianxue snorted coldly.

"Hmph, I'm not worried about you, I'm just reminding you not to overestimate yourself in the future and waste your life in vain!"

Han Feng knew that this mentor was a cold-faced person and refused to admit that he was concerned about him, so he did not point it out and nodded quickly.

"What the tutor said is, the disciple obeys the order!"

Seeing Han Feng's perverted attitude, Dugu Nianxue's cold face calmed down slightly and asked casually.

"How are you injured?"

Han Feng hurriedly replied: "The vice president has given the disciple a "fifth-grade healing pill". His injuries have stabilized at this moment. You only need to recuperate for a few days to recover."

Dugu Nianxue nodded slightly and said with a little hesitation.

"The fifth-grade spiritual medicine is strong in its power. With your current state, you can't refine the medicine power at all, and you will only waste this pill.

Well, follow me and I will help you refine this pill."

After saying that, Dugu Nianxue walked directly into the cave.

Han Feng was stunned for a moment when he heard this.

After being sure that he was right, Dugu's mentor really wanted to help him refine the pills, he followed him happily.

Han Feng followed Tutor 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 of them came to the practice room. Dugu Nianxue stepped back and closed the secret room, allowing Han Feng to sit cross-legged on a cushion, and she sat cross-legged across from him.

Immediately, Dugu Nianxue raised his palm and shot a hot palm force from the air, penetrated into Han Feng's dantian.

With powerful power, he accelerated Han Feng's body to refine the fifth-grade spiritual elixir power.

At this moment, Han Feng only felt a pure, soft and warm energy, centered on the Dantian, spreading from all directions like a tide.

Every time the energy spreads, it will restore your seriously injured body to a point, and the already exhausted spiritual power and qi and blood are also recovering quickly.

The medicinal power of this fifth-grade spiritual pill is indeed beyond my imagination!

He was secretly amazed in his heart. While Han Feng was using the technique to heal his wounds, he subconsciously opened his eyes and looked at Dugu Nianxue, but he happened to meet the other party's cold and peaceful gaze.

The two of them sat opposite each other at this moment, only a few feet away.

With four eyes facing each other, both of them were slightly stunned, and then they looked away at the same time.

Han Feng felt inexplicably that his heart was beating faster, and he couldn't help but think in his heart.

"What's the situation? Has my resistance to beauty decreased? Or is the gaze of Dugu's mentor too lethal?"

Han Feng was very awe of the Dugu mentor and did not dare to think too much. He quickly calmed down and calmed down.

After a moment of silence in the practice room, the atmosphere returned to normal. Dugu Nianxue then spoke.

"How did you defeat the disciple of Tianyuan Academy who comprehended the elements of lightning today?"

When Han Feng heard Dugu Nianxue ask about this, he was stunned.

"Teacher, have you seen me fighting him too?"

Dugu Nianxue nodded while refining the medicinal power for Han Feng.

"Well, I've arrived before you and him have taken action, but I just haven't shown up."

It turned out that Dugu Nianxue arrived a while earlier than Han Feng had imagined.

She just kept hiding in the dark and did not show up. At the same time, she was ready to take action in the dark and rescue Han Feng at any time.

Seeing that Dugu Nianxue was curious about this, Han Feng did not hide it too much.

"Teacher, it's actually very simple. I just used the principle of "object conductivity" to direct lightning to himself."

Han Feng immediately explained the principles in it briefly and tried to explain them as easily as possible.

Although the Lingwu Continent has prospered in force and the strong can even fly to the sky and escape, move mountains and fill the seas, they obviously don’t know much about some ordinary scientific knowledge.

Han Feng defeated Fang Xuan today just using a simple physics principle.

"You said "water and metal" can conduct electricity?"

After listening to Han Feng's explanation, Dugu Nianxue's eyes flashed slightly, but she raised her own doubts.

"I know that metal can conduct the power of lightning. In nature, lightning strikes into rivers and lakes, and the power of lightning seems to be able to be transmitted in water.

But why do I find that the water condensed by ordinary spiritual warriors cannot conduct electricity with water attribute energy?"

Han Feng was stunned when he heard this, but he didn't expect Dugu Nianxue to ask such a question.

I immediately explained seriously.

"Because "pure water" cannot conduct electricity, and the water of rivers and lakes contains many impurities. These impurities melt into the water and form a complex state, and lightning can be transmitted through this."

Dugu Nianxue listened to Han Feng and told the knowledge that did not belong to this world at all.

The clear and deep beautiful eyes actually shone with a light of wisdom, and she seemed to understand it.

"I see."

Dugu Nianxue nodded, but asked again.

"Since both metal and water can conduct electricity, you also touched the blade, why was he electrocuted and you were unscathed?"

"Well……"

Han Feng was surprised for a moment when he heard this. Unexpectedly, Dugu Nianxue had such meticulous thinking and grasped the key points of the problem again.

Han Feng was about to think about how to explain to him the principle of "closed circuit" in physics.

Unexpectedly, Dugu Nianxue's eyes flashed and she guessed.

"Is it because of the principle of "circulation", thunder, long sword, water flow and the human body, the four formed a subtle cycle.

And you are outside the cycle, and energy cannot flow, so it is not damaged."

"I……"

After listening to Dugu Nianxue's analysis, Han Feng was shocked.

If he hadn't been healing 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 the Spirit Warrior to explain the scientific phenomena in her previous life!

Han Feng estimated that if Dugu Nianxue was really born in his own era, he would be a member of the National Academy of Sciences with his wisdom and understanding, and he might be able to become an academician of the National Academy of Sciences.

Is this the legend that you are not afraid of learning mathematics, physics and chemistry well and traveling all over the universe?

Thinking about his terrible achievements in "mathematics, physics and chemistry" and Dugu Nianxue's talent for self-learning, Han Feng couldn't help but feel a little sad.

No wonder they are all moon-level strong men, and they are still Chen-level spirit warriors. This is the difference.

Looking at Han Feng's complex and changing face, Dugu Nianxue hesitated slightly.

"What, am I wrong?"

Han Feng smiled bitterly: "No... what you said by mentor is basically the standard answer."

Hearing this, Dugu Nianxue smiled slightly on her face, but then she praised her.

"Han Feng, your wisdom and knowledge are more amazing than your talent in practice, and even I feel inferior to you!"

After receiving praise from the "Dugu Xueba", Han Feng suddenly had the urge to cover his face and commit suicide in shame and anger, but in the end he could only smile bitterly.

"Uh... it's okay... everyone, each other."

While the two continued to use their energy to heal their injuries, Dugu Nianxue suddenly asked about something again.

"By the way, why don't you agree to be Murong Shu's disciple today?"

Han Feng is still immersed in the "frustration" of being a modern person, but in another world, being crushed by people with scientific knowledge.

Suddenly, when he heard Dugu Nianxue ask about this, he did not think for a while and responded subconsciously.

"Because this person's inappropriate mind, he has something wrong with you..."

Halfway through the words, Han Feng realized that he had missed his mouth and stopped him quickly.

Dugu Nianxue, who was opposite, had a beautiful face at this moment, and her beautiful eyes stared at Han Feng.
