When Lu Tong and the others rushed over, they immediately saw Luo Bing's back and the demon disciple elder who showed his true face after falling.

"Professor Wu?!" Zhang Dongqing didn't even have time to say hello to his master, but he was stunned by the face of the demon elder.

He never expected that this Demon Disciple Elder would be a professor from his alma mater.

Not only him, but Luo Bing was also silent at the moment, as if he was touched.

Lu Tong didn't know this professor, but Qu Jingying whispered in his ear: "This is a retired professor from our school, and he is nearly 100 years old." ”

Luo Bing turned her back to several people, making it difficult to see her expression.

She said coldly: "Why, Daxia treats you well." ”

The old professor, who had receded from the demonic transformation and regained his human form, was covered in wounds, and his old face was full of bitterness.

"I have also made meritorious contributions to Great Xia, and I don't want to betray the country."

His voice became more and more hoarse, "I'm just wondering why the god and demon race can live forever, but our warriors can't. ”

"So, I started researching the true demon blood, hoping to find the mystery of immortality."

"Luo Bing, Zhang Dongqing." The old professor looked at the two of them, "You should know exactly where the bottleneck is for us to continue to develop. ”

"It's lifespan!" When the old professor said this, he was a little excited, "Most of our martial artists, especially those high-end martial artists and mainstays, will begin to decay as they grow older. ”

"Even if it is a martial king, the lifespan is two hundred years at most."

"But it's still too short, and the strong people we have cultivated with great difficulty have fallen one by one because of their lifespan."

"If this continues, there will always be so many strong people in our Great Xia, and we will not be able to accumulate the foundation that can truly fight against gods and demons."

The old professor asked in turn, "If you look at the gods and demons race, they have a long lifespan and can even live forever. ”

"The more time passes, the stronger they become."

"In the long run, we can only be controlled by others, and the more we fight, the weaker we become."

Zhang Dongqing seemed to be slightly touched, but Luo Bing just maintained an indifferent attitude and said, "So, you chose to take refuge in the demon clan and covet the so-called immortality?" ”

"Yes." There was a hint of madness in the old professor's eyes, "Since the research can't produce any results, then I'll simply try it myself." ”

"If I don't go to hell, who will." The old professor said excitedly: "Once I have researched the secret of immortality, won't it solve my biggest problem in Great Xia?" ”

"You ask yourselves, who doesn't want to live forever?" As soon as the old professor's words came out, even Lu Tong couldn't help but shake his head for a while.

Live forever?

Can it really be achieved?

But Luo Bing was unmoved, and snorted coldly: "So, you have become a demon elder, how many clans and how many innocents have you killed?" ”

"This is the price of your pursuit of immortality? Even if you can make a result, will you be able to turn back? ”

Luo Bing said disdainfully: "Martial artists of my generation can naturally explore the immortal martial arts that are suitable for us, how can they fall into the demon path." ”

"Old professor, it's just that you're afraid of death."

As soon as these words came out, the old professor's face suddenly turned pale.

Luo Bing's words pierced his heart deeply.

Only he himself understands that the fundamental reason for taking this step is that he is afraid of death.

At that time, his lifespan was less than five years.

If he can't continue his life with demon blood, he will have to face death.

"But who can resist the temptation when there is something to sustain life in front of them......" the old professor muttered a little distractedly.

"I have indeed killed too many innocent compatriots for my life, what is the purpose of my life......" He seemed to fall into self-doubt.

"Old professor, for the sake of your past merits, I will give you a decent way to die." Luo Bing finally sighed, "You cut yourself." ”

Hehe......

The old professor was already disillusioned at this time, he let out a strange laugh, and the qi and blood in his body were agitated, which really shattered his heart.

After being pierced by Luo Bing's true heart, he was actually dead.

"Take it back and bury it." Luo Bing turned around and looked at Zhang Dongqing with a calm expression, "Don't make a noise, I will report it personally." ”

"Yes, Master." Zhang Dongqing said respectfully.

"Master." Qu Jingying was not so restrained, ran forward and grabbed Luo Bing's sleeve, and asked with a little coquettishness, "When did you come over?" ”

"You don't know, I was almost killed by that demon disciple just now, if it wasn't for my junior brother to save me, I wouldn't have seen you."

Lu Tong saw Luo Bing looking at him, and said a little embarrassedly: "I'm just assisting Senior Sister." ”

Luo Bing didn't retract his gaze, and said with a smile: "I've been following." ”

Groov!

Lu Tong's heart shook slightly, Master has been following them?

So, the master saw it all, including his turtle clone?

However, before Lu Cheng could hesitate, Luo Bing had already continued: "You did a good job this time, you didn't let the demon gangster's conspiracy succeed, and you also assisted the demon suppression army to wipe them out. ”

"When I go back, I will report you for your work." Luo Bing said indifferently.

Lu Tong secretly breathed a sigh of relief, regardless of whether the master saw it or not, but she didn't seem to have any intention of pursuing it.

This can be reassured.

Anyway, he didn't do anything to be sorry for Da Xia, who doesn't have a little secret and hole cards?

Luo Bing didn't stay, and after explaining that they should go back quickly, she flew away alone, and she had to solve the follow-up troubles caused by the beast tide.

"Master is really, it's obviously nearby, and if I didn't make a move earlier, I almost planted it." Qu Jingying saw that Luo Bing had already walked away, so she dared to complain.

"Alright." Zhang Dongqing smiled and said, "If the master had intervened earlier, what else would have happened to us, and the battle exploits would have nothing to do with you." ”

"Senior brother, don't think about it too much." Zhang Dongqing looked at Lu Tong again, "Master hides his traces to ensure that nothing goes wrong." ”

"At the same time, she is also there to protect you from accidents."

"Understood, senior brother." Lu Tong smiled, and there was still some emotion in his heart.

In any case, he can understand Luo Bing's good intentions.

"Also, this mission has changed, and you have personally participated in the battle. Therefore, the school's reward should be able to be upgraded to the S level, and when I go back, I will contact the school about this. Zhang Dongqing smiled again.

When Lu Tong heard this, his eyes lit up, this should be what he cares about the most.

S-Class mission rewards are a completely different concept from before.
