In those years when I was a mortal and a demon

"Zhang Tie, you suffered a lot outside because of me, don't you blame me?" Doctor Mo spoke very gently, with a sense of worry about gain and loss.

"Master Mo said you must not say that. These days, I will remember your kindness to me. If you don't dislike it, I am willing to be your grandson!" Zhang Tie knelt down directly.

When Lu Yuan and Han Li saw this, they didn't even notice. He covered his face and shook his head.

"what?"

Doctor Mo was stunned. It took him a long time to recover, and he quickly helped Zhang Tie up.

"Since you are so thoughtful, I want to accept you as my close disciple, are you willing?"

"Yes, yes, as long as I can serve Master Mo, I am willing!" Zhang Tiegang stood up and knelt down again, kowtowing.

"Master, didn't you say that Senior Brother Han and I are closed disciples? Why is there another one?" Lu Yuan pretended to be dissatisfied.

"Since the door can be closed, it can be opened." Doctor Mo accepted Zhang Tie and was in a good mood.

"I have a mental method that is very suitable for you, but it may be difficult to practice. Are you willing to learn it?" Doctor Mo asked Zhang Tie.

It probably wasn't the Elephant Armor Kung Fu. Lu Yuan was very concerned about the Kung Fu that Doctor Mo said. I think it must have been prepared specially for Zhang Tie by Yu Zitong, maybe he can practice it himself.

Zhang Tie had no objection. From Baixu Hall to Qijue Hall, he had been ostracized and even almost lost his life. Now that he can return to the Divine Hand Valley and keep company with Lu Yuan Han Li, he is naturally happy. As for what kind of exercises you do, it doesn’t matter at all.

"Practice and try the mental method here first. I will check your progress in half a year." Doctor Mo took out a piece of paper and handed it to Zhang Tie.

"Write it down quickly. Remember, don't spread it outside, otherwise..." Doctor Mo's voice suddenly turned cold.

"Yes." Zhang Tie agreed and quickly began to memorize it silently.

"What are you staring at? I didn't say you could practice." Doctor Mo noticed Lu Yuan leaning towards Zhang Tie and scolded him quickly.

Lu Yuan curled his lips and turned away.

Hum, since you gave it to Zhang Tie, I will get it sooner or later.

As if he had heard what Lu Yuan was thinking, Doctor Mo specifically told Zhang Tie that he should not tell Lu Yuan the content under any circumstances. Then while waiting for Zhang Tie, he closed his eyes and meditated.

Speaking of which, this guy's brain is really not very bright, and he couldn't memorize a hundred or ten words in a long time. Lu Yuan looked up at Doctor Mo. Although he was still concentrating with his eyes closed, his face was already a little dissatisfied, and his lips were trembling, as if he was suppressing anger.

"Lu Yuan absolutely can't practice. If I say no, I can't!" Doctor Mo suddenly shouted angrily, shocking everyone.

Zhang Tie stopped memorizing the formula and suddenly knelt on the ground, tremblingly saying something like "I will never tell Senior Brother Lu".

"Okay, you two can go and do whatever you want. Just leave Zhang Tie here alone." Doctor Mo was still angry and drove Lu Yuan and Han Li out.

"What's wrong, Master Mo? Brother Zhang didn't tell you the content of the formula!" After leaving the hall, Han Li complained quietly to Lu Yuan.

"There is probably something fishy about this formula. We must get it and study it to prevent Brother Zhang from suffering a loss." Lu Yuan followed the words.

Lu Yuan knew that Dr. Mo's violent outburst just now was definitely not directed at Zhang Tie. He thought that he had been closing his eyes and concentrating just now, probably communicating with Yu Zitong.

Could it be that Yu Zitong was suspicious of him and wanted him to try it too?

"How to do this? Brother Zhang is a stubborn person. If Master Mo doesn't let him tell it, he will definitely not tell it." Han Li asked worriedly.

"You're stupid. You just said you wouldn't let Brother Zhang tell me. I didn't say I wouldn't tell you. You can find a way to get it and then reveal it to me, okay?"

"Is this okay? I'm afraid it won't be easy, right?" Han Li looked embarrassed.

Lu Yuan looked at him and said to himself, "You are just pretending to me. With your intentions, isn't it easy to fool Zhang Tie?"

"Don't you suspect that the master has bad intentions, so you have to start with the formula!"

"That's right, leave this matter to me." Han Li was moved by Lu Yuan and nodded in agreement.

I have to say that Han Li was very good at dealing with Zhang Tiezhen, and he deceived him with the formula that night.

Lu Yuan was extremely excited with the formula he had obtained, and immediately found an excuse to send Han Li away and try to practice.

In less than a month, Lu Yuan noticed an extra trace of energy in his meridians. Unlike Han Li, there was cool energy in Han Li's body, but slightly warm energy in his own body. At the same time, Zhang Tie, Still no movement.

I have heavenly spiritual roots, so I should practice fast. Lu Yuan thought this way, but now he just doesn’t know the properties of his spiritual roots. In this regard, Lu Yuan also made a preliminary judgment.

Thinking back to the Golden Spirit Grass that I accidentally ate, judging from the name, I can basically guess that it is metallic.

Moreover, through martial arts training, Lu Yuan found that he had a natural tacit understanding of weapons. Especially weapons such as swords made of fine steel. Holding it in your hand, it feels like a part of yourself, like an arm.

He quickly found Han Li and asked him to come into contact with the five elements. Sure enough, Han Lizai had an indescribable feeling about everything except gold.

Lu Yuan found Zhang Tie again and tested it in the same way. It turns out that Zhang Tie is very sensitive to things with fire attributes and has some feelings for metal and earth. There is no response to the two attributes of wood and water.

now it's right! Lu Yuan finally confirmed his guess. Han Li has four attributes, and his spiritual roots influence each other, so the induction of the corresponding attributes is not that obvious.

As a single-attribute metal spiritual root, I am naturally close to gold and iron without the influence of other factors.

After determining the attributes of his spiritual roots, Lu Yuan was no longer fettered and began to devote himself to cultivation. In less than three months, the first level of training was completed.

Because Doctor Mo only gave Zhang Tie the first level of skills, Lu Yuan had to suspend his training and wait for Zhang Tie to master the first level.

Zhang Tie is worthy of his qualifications as a true spiritual root. He has already broken through the first level within half a year.

So without waiting for an examination, he asked for the second-level formula from the stunned Doctor Mo.

Of course, Lu Yuan naturally got it through Han Li immediately.

The second level is more difficult than the first level, but for Lu Yuan with Tianlinggen, this is not a problem. Three or two months later, he completed it one step ahead of Zhang Tie.

Zhang Tie, on the other hand, was not that good. It took him half a year to practice only to about the middle of the second level.

After Doctor Mo learned of the situation, he quickly spared no effort to refine the elixir and assist Han Li and Zhang Tie in their cultivation.

When the medicine garden ran out of medicinal materials, we searched all over the mountains and fields for medicinal materials. Including several hills near Qixuan Gate, he had pulled out even a weed and tested its medicinal properties.

Finally, in the third year after Lu Yuan entered the Valley of Divine Hands. Due to the addition of Zhang Tie, the precious medicine in Doctor Mo's hands was used up early. Without the aid of elixirs, Zhang Tie's cultivation speed dropped significantly, and Han Li's cultivation became even worse. Both of them experienced stagnant cultivation.

There was no other way. After thinking about it for a long time, Doctor Mo finally decided to go out and look for some medicine.

Because he didn't know when he would come back, before leaving, he gave all the first four levels of skills to Han Li and the others.

It was at this time that a few people knew the names of the two mental techniques. One is naturally Changchun Gong, and the one given to Zhang Tie is called Five Elements Golden Art. As soon as Lu Yuan heard this name, he knew that it was just a cheap guy, not very sophisticated.

As for Lu Yuan, Doctor Mo's original plan was to take him out with him to gain some knowledge. But he was worried that something would happen to Han Li and Zhang Tie, so he finally decided to leave Lu Yuan behind. Because today's Lu Yuan is no longer weaker than the guardians in the sect in terms of martial arts.

Just in case, after laying the foundation, he taught all the magic silver hands. According to his estimation, as long as Lu Yuan is willing to put in the effort to practice, he will definitely achieve success within two years.

Lu Yuan didn't expect Doctor Mo to care so much about him. Looking at his rickety body, he couldn't help but feel sympathy in his heart. Thinking that Dr. Mo would definitely encounter enemies when he went out this time, he pretended to tell Dr. Mo's fortune on the spot.
