After simply straightening out the stagnant meridians in his body, Yu Chen quickly got up, then turned his head to look at Doctor Gu and said, "Senior, we can go." ”

Seeing that Yu Chen had recovered so quickly, Doctor Gu couldn't help but look stunned, his eyes fell on Yu Chen's body, and he immediately smiled.

"I didn't expect you stinky boy to have a lot of secrets... Hehe. ”

Physician Gu's voice fell, and then with a wave of his hand, a faint mist spread from his hand, covering the place where he had just fought in an instant.

A scene that shocked Yu Chen appeared, only to see that after countless faint mist melted into the ground, the traces of the battle just now continued to disappear at a speed visible to the naked eye.

"Senior, what kind of means are you!?" Yu Chen couldn't help but exclaim.

Isn't that amazing? I'm afraid it's more advanced than all these martial arts techniques he has learned.

Hearing this, Physician Gu looked stunned, a flash of remembrance flashed in his eyes, and then he shook his head slightly, and said, "You can't learn this method of mine for the time being, if you want to learn, then wait until the realm of the grandmaster to come to me." ”

Hearing the other party's words, Yu Chen became even more curious, what kind of means could he only learn when he reached the realm of a grandmaster?

Although Yu Chen wanted to continue asking, he also knew that everyone had their own secrets, and it would be rude to continue to ask, not to mention that Doctor Gu had never asked his secrets.

"Let's go, stinky boy, lest some puppies chase after you again."

Doctor Gu smiled faintly, pulled up the remaining dust and continued to hurry.

And Yu Chen didn't let go of the gap in his hurry, and went straight to the character panel to check the effect of his newly obtained equipment Star Rainbow Sword.

Rainbow Sword (Sealed Status): Crafted from star meteorite, it has the function of gathering starlight, and can only double the user's combat power under starlight.

Note: When used in conjunction with the Rainbow Sword, the seal of the Rainbow Sword can be lifted, all functions of the Rainbow Sword will be unlocked, and all effects will be increased by a factor of five.

Seal? Celestial Formula?

Yu Chen was stunned for a moment.

The Star Rainbow Sword is indeed a good weapon, and it is already an exaggeration to be able to double the combat power of the user, and this is still in a sealed state.

If he can cooperate with Xingchen Jue to lift the seal, Yu Chen estimates that he will be able to beat all the acquired martial artists with the Xinghong Sword.

It's just that how should I get this star formula?

Yu Chen immediately called up the system, intending to ask for clarification.

"System, how should I get this star trick?"

"Ding, by completing the system task, the host can get random rewards, have a certain probability of getting the Star Formula, or go to the system mall to buy it by yourself."

"However, Xingchen Jue is an S-level exercise, and the host cannot unlock the purchase qualification before he is promoted to the innate martial artist."

Yu Chen's mood, which was originally quite high, quickly fell down after hearing the last paragraph.

However, I couldn't help but secretly marvel that the Xingchen Jue turned out to be an S-level exercise, so wouldn't the Xinghong Sword used with it also be a high-level weapon?

It is estimated that it should belong to the same level of weapon as the Spitfire Meteor in his hand.

Thinking about it like this, Yu Chen couldn't help laughing again, fortunately he didn't choose the Northern Spiritual Exercise, otherwise his intestines would be repentant now.

However, he was also very glad that the Star Rainbow Sword was in a sealed state, otherwise it would not have been possible to become his reward together with the Northern Immortal Exercises.

And based on this, Yu Chen also deduced what the system judged to be a skip kill.

Just like the strength of his apprentice martial artist to kill Bai Wuchang, the strength of the martial artist to kill the black bear of the acquired realm also crossed two levels.

This also means that the further back Yu Chen wants to kill the level, the more difficult it will be, especially when it comes to the realm of the acquired martial artist, it is a fantasy to kill the strong grandmaster.

I can't help but feel a little sad when I think of this, but there are fewer and fewer opportunities like this.

What's going on!?

Physician Gu looked at Yu Chen, who was crying for a while, laughing for a while, happy for a while, and sad for a while.

If he wasn't sure that the other party was fine, I'm afraid he would have thought that Yu Chen's head was hit by a black bear.

It's just that what is this stinky boy thinking, and his mood changes are so rich?

……

Shortly after the two left.

A group of men in black stopped at the place where the black bear and black wolf were fighting with Physician Gu and Yu Chen.

I saw a man in black constantly shaking his nose in mid-air, breathing hard to distinguish the smell in the air.

"How's that, black cat, do you know which direction they're chasing after you?" The man in black asked.

Hearing this, the black cat shook his head slightly, and a look of doubt flashed in his eyes, "It's really strange that the smell of the black wolf and the black bear was cut off here, and it was very abrupt." ”

"I can't even smell anything about them."

Hearing the black cat's words, the leader of the men in black suddenly fell silent.

According to the words of the black cat, it is obvious that the black bear and the black wolf have encountered an unknown and powerful existence here, and the traces of existence have been erased.

But now it's certain that the black cat and the black wolf are dead, but it's just ...... The leader of the men in black looked around, almost indistinguishable from the rest of the place.

It looked like the black bear and the black wolf had been killed with a single blow, and they couldn't even make a splash.

"Black cat, where is it further from this direction?" The leader of the men in black asked in a deep voice.

"My lord, further on is the imperial city of the Great Zhou Dynasty."

Imperial City...... The leader of the man in black narrowed his eyes slightly, looking in the direction of the imperial city, and a trace of murderous intent flashed in his eyes.

"Catch up! The people I want to kill in the Zonglou can't live! ”

With a wave of his hand, the man in black immediately followed behind each other and rushed in the direction of the imperial city.

I don't know how long it took.

Yu Chen and Physician Gu finally came to the Imperial City, and after passing the identity test of the soldiers guarding the city, Physician Gu brought Physician Gu to the front of the Imperial Palace.

"Thank you seniors, seniors are very kind, and the rest of the dust should be remembered for a lifetime."

Before parting, Yu Chen bowed respectfully to Doctor Gu, his expression full of respect.

Hearing this, Physician Gu waved his hand indifferently and said, "I'm just entrusted by someone, so there's no need to do this." ”

As the words fell, Physician Gu turned around and was about to leave.

Seeing this, Yu Chen hesitated for a moment, and finally stepped forward and stopped the other party, "Senior, please stay!" ”

"Huh? Is there anything else you can do? Physician Gu asked with some confusion.

"If the seniors don't dislike it...... Please allow the juniors to call you teacher! Yu Chen said.

For the white-bearded old man in front of him who did not hesitate to spend his internal strength to save himself and guide himself to protect the Dharma, all he had was endless gratitude and awe.

The other party did not rely on his strength to point fingers at him, but was very kind, and treated him patiently and meticulously like a teacher.

In Yu Chen's heart, Doctor Gu was a teacher on his way forward.
