After more than ten years on the mountain, you will become invincible when you come down.

Lu Feng squinted his eyes and looked at Mr. Xu. Will the fox's tail be exposed now?

Although Lu Feng didn't know what he was going to take out, Lu Feng always felt that something was wrong...

It is absolutely abnormal for old comrades who have not seen each other for decades to suddenly return to China and to get married as soon as they return home...

"What?" Mr. Chen asked doubtfully.

"Haven't you always wanted to be a master? Look at your current cultivation level. It doesn't matter whether you are high or low. With this thing, I guarantee that your cultivation will improve by leaps and bounds..." Mr. Xu said.

"Oh? Are there such treasures in the world?" Mr. Chen asked doubtfully.

"Nowadays, technology is so advanced, what kind of things can't be made? Old Chen, you are behind the times..." Mr. Xu said and took out an exquisite small box.

Mr. Chen looked at the small box curiously and watched Mr. Xu open it...

Inside the box lies a potion in a glass bottle...

Lu Feng looked at the medicine in the box and suddenly thought of John, who he had invited to join their biotechnology company. Their company was researching this kind of reagent. Could it be that this company produced it? Lu Feng is not sure whether there are other companies studying...

"Lao Xu, is this the treasure you are talking about?" Mr. Chen asked doubtfully.

He also couldn't understand, could just such a thing really make his cultivation level soar?

"Of course, don't underestimate this potion. You only need to inject this potion to reach the realm of what you call a grand master. Old Chen, you should understand the meaning of a grand master better than me, right?" Mr. Xu said proudly. said.

Mr. Chen was startled and stared at Mr. Xu in disbelief and said, "Old Xu, are you telling the truth? Can such a small glass bottle really have such an effect?"

"Of course, do you know how strong I am now? Even if a cow stands in front of me, I can kill it with one punch. Even if the Dragon Army of China is standing in front of me now, he dare not stand in front of me. What a mistake..." Mr. Xu said.

Mr. Chen's mouth opened wide. Although he hadn't seen him for decades, he knew his comrade very well. He was a wild man like him, and there was no way he could cultivate to such a level...

Seeing Mr. Chen's surprise, Mr. Xu became more and more proud and said again, "Old Chen, if you don't believe it, I will show you what powerful power is!"

"Okay... then please follow me to the martial arts training ground to try..." Mr. Chen said.

"No need, just use the big stone in your yard to practice. You should keep an eye on it..." Mr. Xu said and walked towards the big stone in the yard.

Lu Feng frowned at Mr. Xu, because he could not find any energy fluctuations in his body. However, looking at Mr. Xu, it didn't look like he was lying. He was obviously confident. So, was he really what he said? So powerful? If it is true, then where does he get his power from?

Everyone followed Mr. Xu to the courtyard, where a landscape stone lay quietly in the courtyard...

"Old Chen, I believe you know more clearly than me how hard this stone is, so keep an eye on it..." Mr. Xu said.

Mr. Xu slapped it down without hesitation...

There was a loud noise of "Bang...".

The stone shattered with the sound, and small stones scattered on the ground...

Incredulously, Mr. Chen went to look at the broken stones on the ground. He could crack the stone with one slap, but he couldn't do it. He could smash such a big stone into powder...

Xiao Xu held his head high and felt proud to have such a grandfather. His eyes when looking at everyone revealed a sense of superiority...

"Boy, have you seen how powerful my grandpa is? If you know better, you should get out of here. Otherwise, if this slap hits you, hum... do you think what the consequences will be?" Xiao Xu He snorted coldly.

"There are indeed two moments..." Lu Feng praised.

However, what Lu Feng admired was not how powerful Mr. Xu was, but that the person who developed this reagent did have something...

During the whole process, Lu Feng did not feel any special energy running in his body, which meant that this reagent stimulated his potential, enhanced his own strength, and broke the shackles...

This is equivalent to creating another cultivation system. Although he has just started, it has already achieved initial results. The key is that we still don’t know which step he has achieved...

However, Xiao Xu thought Lu Feng was talking about his grandpa’s misdeeds...

"Boy, now you know you're afraid, I might as well tell you that although I'm not as strong as my grandfather, I'm more than enough to deal with you..." Xiao Xu said proudly.

"Just you? Go back to your mother's womb and practice for another eighteen hundred years, and see if you can deal with me then..." Lu Feng said disdainfully.

"Boy, you are looking for death! Who can't brag? If you have the ability, come and fight!" Xiao Xu said angrily.

"Hey... young people, please don't keep fighting. Everyone is a guest. It won't be good if you two fight and hurt anyone..." Mr. Chen quickly tried to persuade him.

He didn't know how powerful Lu Feng was, but he didn't want to see Lu Feng suffer a loss. Especially after seeing how powerful this potion was, he was still a little afraid that Lu Feng would lose to him and get injured...

"That's right, you have to fight at your Grandpa Chen's house every now and then. How is that polite? How many of the younger generation are your opponents now? We don't do bullying!" Mr. Xu scolded.

Lu Feng silently rolled his eyes at the two of them. This seemed to be scolding his grandson, but in fact he was pretending to be cool, pointing out that among the younger generation, it was already difficult for his grandson to find a rival...

"Lao Xu, tell me, under what conditions can you give me this reagent?" Mr. Chen asked.

He was really moved. After taking this reagent, he could reach the realm of the Grand Master. This realm can be almost traversed in China...

If he has this reagent, for him, his dream will be fulfilled, and for the Chen family, it will be a qualitative leap, going out of Zhonghai, out of Jiangnan Province, and even towards Yanjing...

Because he has not heard yet who has reached the level of a great master...

But he also knew that there was no free lunch in the world. Mr. Xu could not give him this reagent unconditionally. Even if he could give it to him, he would not feel at ease with it...

"Old Chen, we have been comrades-in-arms for so many years, it would be too hurtful to talk about interests with me..." Mr. Xu said.
