You know, he is only at the fourth level of Qi training now. Even if he uses the Spirit Gathering Array to practice for half a day every day, it will take him nearly a month to break through to the fifth level.

With the Eight Desolate Soul-Swallowing Cauldron, he could break through in half a month without practicing.

If you practice hard in the meantime, or swallow some precious medicine that can greatly enhance your strength, this time can be further compressed!

In less than half a month, he broke through from the fourth level of Qi training to the fifth level!

This speed may not be a big deal in those high-level sects, but in the Lu family and in Liuhe County, it can be considered a genius that appears once in a century!

Suppressing their excitement, Lu Zhengzhi and Lu Tieshan left the house.

"Brother Zhi." Lu Tieshan wanted to say something to express his gratitude, but Lu Zhengzhi handed the storage bag he had taken from Lu Fanzhi to Lu Tieshan.

"Ah? What's this for?" Lu Tieshan looked puzzled, but he had already put out his hand to refuse.

"Brother Zhi has enlightened me, taught me spiritual techniques, and even offended Lu Fanzhi's lineage for me. It's already difficult for me to repay you, so how can I accept your treasure?"

Lu Tieshan's expression was very firm, he just didn't intend to accept it.

Lu Zhengzhi was both angry and amused.

Silly boy, you are truly repaying me by accepting my investment.

However, looking at Lu Tieshan's expression, he knew that there was no way this kid would accept the storage bag, so he didn't force him.

When it comes to investment, you also need to consider the right time, place, and people.

Don't force things when people are not happy with you, only then can you make yourself happy.

Lu Zhengzhi took back the storage bag and said, "If that's the case, then forget it."

He turned and went back to his cabin.

Since Lu Tieshan doesn't want these treasures, he can use them to test the effectiveness of the Eight Desolate Soul-Swallowing Cauldron.

"Hey! Brother Zhi, please teach me when you are free! I can produce spirit stones!" Lu Tieshan hesitated for a moment, but still shouted while looking at Lu Zhengzhi's back.

When Lu Zhengzhi heard this, the corners of his mouth that were originally raised widened even more.

"No need for spirit stones. When you've stabilized the Flame Six-Combination Record, come back to me. Don't think it's a bother, I'm always happy to help!"

After that, he waved goodbye and walked towards the cabin.

Lu Tieshan looked at Lu Zhengzhi's back and couldn't help but feel his eyes moist.

Brother Zhi, that’s great.

In order to help me, he offended Lu Fanzhi, the most powerful person in the clan, and even gave me the things he won. He didn't look down on me and told me to come to him anytime.

I, I must treat Brother Zhi as my own brother from now on and never let him suffer revenge!

Lu Tieshan made a secret decision.

In the Tibetan Library.

Mei Wenxue looked at Lu Zhengzhi who was waving goodbye, a hint of hesitation in her eyes, "Are you willing to help?"

"Then, you should forgive my misunderstanding, right?"
