"Who are you! There is no one on the list of innate masters of the Sect Killing Building! The black wolf said in shock and anger.

Hearing this, Doctor Gu sneered twice, then shook his head slightly, and said, "It seems that your Sect Killing Building has always been a small organization, and even I don't know about it. ”

"My surname is Gu."

Surname Gu... Surname Gu... The black wolf muttered twice in succession, and then as if he had thought of something, he suddenly looked up at Physician Gu.

"Are you, Gu ...... Hmmm......"

Before the black wolf could finish speaking, he saw Physician Gu wave his hand, and several vines suddenly appeared on the black wolf's body, absorbing the other party's vitality in the blink of an eye.

He didn't even let go of the bones, and in the end only a few pieces of clothing that the vines couldn't dissolve, looking at what the black wolf left behind, Physician Gu waved his hand again, and a pale green mist quietly corroded the remaining things.

Meanwhile.

An angry howl came from Yu Chen's side, and Physician Gu turned his head to look and found that half of the black bear's head had been slightly dented by the beating.

It turned out that Yu Chen was unable to move with the help of the black bear's missing arm, and kept wrestling with him, finding the right time to keep punching.

However, the black bear's skull was too hard, and Yu Chen used the Nine Spirit Fist five times to break the black bear's defense, only making the other party feel more pain.

Fortunately, the hard work pays off.

Under the full bombardment of the sixth Nine Spirit Fist, Yu Chen finally pried open the black bear's skull, and in an instant, red and white things scattered and splashed in all directions.

At this point, the two Zonglou killers who pursued them were dealt with by Yu Chen and Physician Gu.

"Ding! Congratulations to the host for successfully killing the Black Bear of the Acquired Martial Realm Realm! ”

"Get Reward: Weapon: Star Rainbow Sword/A-level Martial Arts Northern Shengong (choose one of the two)."

After skipping the level to kill the black bear, the system's prompt sound also sounded in time.

Yu Chen was stunned for a moment, and then chose the weapon Xinghong Sword without hesitation, as for the Northern Shengong, it had long been abandoned by Yu Chen.

Because he found that the A-level Gong Fang Zhongshu was much more advanced than the same A-level Northern Pluto Divine Skill, and the fact that the non-attributed internal force could be transformed at will was not comparable to the Northern Pluto Divine Skill.

If it weren't for the attributeless internal force, Fang Cai's battle remnants don't know how many times they would have been killed by the black bear.

Moreover, the Northern Shengong absorbs the power of others and has to transform itself, and the efficiency is too slow, so Yu Chen didn't even look at the specific role of the Xinghong Sword.

"Stinky boy, I didn't expect your strength to be quite good, but it impressed me, an old man."

Doctor Gu quietly came to Yu Chen's side, looked at the other party with a smile and said.

Frankly speaking, he didn't expect Yu Chen's strength to be so strong, facing the black bear who opened the three-layer exercises, he could still kill the other party, and the martial arts realm would be able to kill the martial artists of the acquired realm.

Although it is said that Yu Chen relies on the poison of the Ten Thousand Poison Demon Blade, its strength is also not to be underestimated.

After all, ordinary martial artists or even great martial artists face black bears, not to mention forcing the other party to open the third layer, I am afraid that the first layer will be crushed by the black bear.

A good martial arts seedling.

This is Physician Gu's pertinent evaluation of the aftermath.

"Senior Muzan, if it weren't for your help, I'm afraid I would have been a pile of dry bones by now." Yu Chen waved his hand again and again.

"By the way, boy, can you let me take another look at the Ten Thousand Poison Demon Blade you control?"

Physician Gu said suddenly.

Hearing this, Yu Chen's expression suddenly stunned, Ten Thousand Poison Demon Blade? I guess I'm talking about his Spitfire meteor, right?

It's just that... What does Physician Gu want to see this thing for?

Although it was one of the secrets of the Flying Fire Meteor's Aftermath, Physician Gu was kind to him, so Residual Dust did not hide it, but generously took out the Flying Fire Meteor and handed it to Physician Gu.

The latter did not catch it with his hands, but held up the Spitfire Meteor with pure internal force and looked at it carefully.

"It's really strange, this is obviously the Ten Thousand Poison Demon Blade, but why can't I feel any demonic energy on it?"

Physician Gu looked the Flying Fire Meteor up and down, shook his head in confusion, and then returned the Ten Thousand Poison Demon Blade to Yu Chen.

"I don't see anything famous about this thing for the time being, but the aura it exudes is exactly the same as the demon soldiers I know."

"If you want to use it, you must be careful, maybe this demonic qi has been sealed."

Physician Gu said with a serious face.

Yu Chen was a little curious, "Senior, what is this Ten Thousand Poison Demon Blade?" ”

Physician Gu looked stunned, then sighed helplessly and explained, "This Ten Thousand Poisonous Demon Blade is the most vicious demon soldier I have ever seen in my life. ”

"The process of its casting alone is enough to consume tens of thousands of resentful souls, supplemented by flesh and blood to build a foundation and refine it."

"The reason why the Ten Thousand Poison Demon Blade is called a demon soldier is not only because of the process of its casting, but also because almost all of its dozens of masters ended up falling into the demon path and dying."

"And all the wielders of the demon soldiers will eventually be manipulated by the demon soldiers and lose their sense of self, so I advise you to be careful of this demon soldier, although I don't feel any demonic energy on it now."

Doctor Gu was afraid that Yu Chen would not listen, so he hurriedly emphasized it again.

Yu Chen nodded solemnly, but unlike the calm on the surface, Doctor Gu's words caused an uproar in his heart.

This Flying Fire Meteor is actually the same breath as the Demon Soldier Ten Thousand Poison Demon Blade?

Could it be that after the Ten Thousand Poison Demon Blade was gifted to him by the system, he carried out the sealing service intimately by the way? Or maybe the Ten Thousand Poison Demon Blade didn't know what it went through, and was finally used as a system reward?

"System, will all the rewards I get cause a backlash on me?"

In order to seek truth, Yu Chen hurriedly called the system out.

"Ding, as long as the host uses the system reward reasonably and normally, it will not regurgitate the host." The system's indifferent mechanical sound sounded.

Yu Chen couldn't help but fall into deep thought.

As long as it is used reasonably and normally, it will not regurgitate? That is to say, unreasonable and abnormal use will cause backlash?

Yu Chen couldn't help but think of what the ancient physician had just said about the Demon Soldier Ten Thousand Poison Demon Blades, and he suddenly shuddered.

The Flying Fire Meteor in his hand can't really be a Ten Thousand Poison Demon Blade, right?

As soon as he thought of the scene where he might fall into the demonic path, Yu Chen couldn't help but shudder.

Although he doesn't know what it's like to fall into the Demon Dao in this martial arts world, judging from countless TV series and experience, I'm afraid the consequences will be very serious, right?

After all, even a person like the black bear and black wolf who has cultivated the Beast Sutra is only called a crooked and evil way, so falling into the demon path should be even more terrifying, right?

"Thank you for the reminder."

Yu Chen looked at Doctor Gu gratefully again, this white-bearded old man really did his best to help him.
