Speaking of which, Tony had already taken over Peter's class, and Zhao Yu was slapped by him, so he was the most. He had already practiced conditioned reflex. When he saw that Zhao Yu was moving, he hurriedly dodged.

"The three-month period originally set now seems to be invalid." Zhao Yu ignored Tony and said with relief: "The cultivation progress of each of you exceeds the requirement of pushing the door open. Therefore, for the master, you have decided that you, like registered disciples, can enter and exit the cave at any time from today."

When several disciples heard this, their expressions were different.

Like Cindy, she treated her cultivation as a hobby and looked unmoved. If it were not necessary, she decided not to leave the sect in a short time. Anyway, her parents knew that she was practicing here, and there was no big concern outside, and Peter was also in the sect!

Wolverine Logan showed excitement on his face.

To be honest, he had wanted to go out long ago. Since he recovered his memory, he wanted to go out and find what he had lost. Now that he can go out, of course he can't wait.

In fact, this is also the biggest reason why as a mutant, even Cindy's cultivation progress is not as good as Cindy.

Tony is just as impatient as him.

For Tony, the playboy, the world of bright lights and wine outside is the yearning. If you stay in the sect all your life, it would be better to kill him!

There is also Natasha, who also plans to leave the cave. After all, she is from SHIELD. Since Zhao Yu has no restrictions, she has to go back to perform her duties.

The other people only looked slightly moved, and they were slightly moved, thinking or not thinking, all in a moment.

"but,"

Seeing their appearance, Zhao Yu smiled secretly and said, "Unless necessary, the personal disciples must stay in the sect to practice for five days every ten days!"

It can let them relax, but not indulge them!

When Tony heard this, his face was immediately pulled down: "No?"

"This is the sect rule." Zhao Yu was speechless: "Especially you, Tony. I really don't give you any restrictions. Once you go out, you won't be able to fly to the sky?"

"But Master, I plan to make a pair of armor, and I must use equipment. The sect does not have those equipment." Tony explained.

"How is that..." Zhao Yu nodded slightly: "Then my teacher asks you, how long does it take to make armor?"

"One month, no, half a year!" Tony said a little and immediately changed his words.

"Then it's two months." Zhao Yu said decisively: "In two months, if my teacher can't see your armor, hehe..."

Facing Zhao Yu's cold eyes, Tony shivered and his body straightened, like a soldier: "Please ensure that the mission is completed!"

Zhao Yu nodded and looked at Logan who wanted to speak but stopped: "Your situation is clear, so there is no restriction. But remember to bring enough energy pills when leaving, and you cannot let go of your practice!"

"Thank you, Master." Logan breathed a sigh of relief and said gratefully.

"Then let it be." Zhao Yu said: "If you want to leave the cave, go and prepare. The master is in the back hall. If you have any questions, come to the back hall to find me."

After saying that, he turned around and disappeared.

...

"Haha, I can finally leave this ghost place." As soon as Zhao Yu left, Tony let go. He opened his arms to embrace the air: "Ah, the lights and wine, and the beauty is my world's number one genius, Tony Stark, life!"

Seeing this, several fellow disciples curled their lips and walked away in groups of three or three, leaving a Tony messy wind.

"Oh, I said you don't want to express your opinion?!"

He chased after him and chatted endlessly.

"My opinion is, shut up." Natasha betrayed him: "You are the elder brother, you know that you are embarrassed?"

"If you are outside, don't say he is our senior brother."

Tony looked helpless: "Just just kidding, don't you have to be so serious, right?"

The others shrugged.

"Okay, I won't play with you, I'll go find the master." Tony smiled and said, "By the way, what are you going to leave? Let's have a treat together. I'll treat you tonight, the best bar in Manhattan."

"There is wine?" Logan was immediately attracted to his attention.

"Of course, the best wine." Tonyan said.

"That's my part." Logan nodded: "But I don't have money, I know you have it."

"Senior brother, don't be polite." Tony was so arrogant.

"I won't be with you anymore." Natasha shook her head: "The director is waiting for me to go back."

"I think you'll just quit. Are people in places like S.H.I.E.L.D.?" Tony said disdainfully: "If you want me to say anything, it's better than being an agent."

"I'm used to it." Natasha didn't care about Tony's statement: "I've been trained as an agent since I was a child, and I'm still here. I don't know what to do if I don't become an agent."

"What about you guys?" Tony asked Riven, Harry and Cindy again.

Harry hesitated: "I plan to go back and see my father first, he is not in a good condition."

"I'll stay here," Cindy said.

"Me too."

Tony had to spread his hands: "Okay OK, okay, it's all so boring."

As he spoke, he held Logan's shoulder and laughed, "If they don't go, we'll have fun tonight." As he said, he showed a look that even a man understood.

Logan also laughed.

Several women snorted and quickly opened the distance.

"That's all." Tony said: "Logan, I'll go to the back hall first. I have a question to ask Master. If you have anything to clean up, just pack it up and wait for me to come out and let's go together."

Logan said he understood.

Tony turned around and headed towards the back hall.

"Come in."

Before Tony could knock on the door, Zhao Yu's voice came from inside the door.

He pushed open the door and walked in.

"Is there something wrong?"

“Yes, two.”

Tony sat cross-legged in front of Zhao Yu, showing a flattering smile: "Master, should I untie that tight hoop curse? Look, I am different now than before, right?"

Zhao Yu looked at him: "Although my teacher has sharp eyes, I didn't see it."

Tony's face froze: "But Master, there's something in his mind, it makes people worry about it all day long, and it's not very comfortable."

"That's right. You have to have a concern so that you won't run the train." Zhao Yu said: "As for the tight hoop curse, when will you complete the foundation building, advance to refine Qi, and refine magic power, and when will you unlock it for you by your master?"

Seeing that Zhao Yu's expression was uncontroversial, Tony had to suppress: "Okay, okay, you have the final say anyway."

After complaining, he said seriously: "Master, I just said that I would make a pair of armor is not a joke. After being kidnapped in that Afghanistan incident, I had this idea. If I hadn't practiced here for two months, I would have done it. But now I have a better idea."

He said, "Just like you said, what kind of chemical reaction will a combination of talismans and machinery occur? I can't wait!"

Zhao Yu nodded with a smile: "But with your current realm, it is difficult to engrave talismans on steel."

"Yes, I'm just worried about this." He frowned and said, "Does it be necessary to have magic power to engrave permanent talismans?"

"Not necessarily." Zhao Yu smiled and said, "If you are willing to work hard."

Tony's expression moved, and then he shook his head: "Let's forget it. If you want to engrave the talisman with your heart and soul on a piece of armor, I'm afraid you will never see me again."

"Just know." Zhao Yu said seriously: "You can eat as much as you eat. If you don't have that realm, you will definitely retaliate against yourself if you have the power of that realm. The inscribed permanent talisman without sequelae must have magic power, otherwise it will not work."

"I guess mana should be an energy, right?" Tony asked, not giving up.

"Energy...it can be said about this. When you have magic power, you will understand." Zhao Yu said: "I know what you are thinking. Use some kind of energy to replace it? Electricity, solar energy, and even nuclear energy? Wrong!"

He said: "Magic power is not simply a kind of energy, it is made up of human will combined with various inspirations of heaven and earth, and refined with the spiritual energy of heaven and earth. Can you make electricity and solar nuclear energy possess human will? If not, the talisman will definitely not succeed."

When Tony heard this, most of the luck in his heart disappeared.

"No shortcuts can be taken in anything. Even if you make armor, don't you still have to have the corresponding academic foundation? Anyone can create it out of thin air? You are a smart person, don't you understand. Armor can be made first, or even tried to do some experiments combining with talismans. It's not too late to improve it after practicing magic power."

When Tony heard this, he nodded slightly: "I understand."

"Just understand." Zhao Yu said: "But if your armor is combined with talismans, you must pay attention to the selection of materials." As he said, Zhao Yu took out a booklet and handed it to Tony: "Your path is mainly talismans, and you must also combine the method of refining weapons in the future. In this book, there are some basic talismans and refining materials, mainly the characteristics of the materials. If you study it carefully, it should be helpful to you."

When Tony heard this, his eyes lit up. He quickly opened the book, couldn't take a look, and his face pulled down: "Master, what is this black iron?"

Zhao Yu laughed: "Don't look at the name, look at the characteristics of black iron. Black iron is an essence extracted from steel. A ton of steel can probably extract one or two black iron. Of course, you don't have this ability now. But some special environments in nature will produce natural black iron, so you might as well start from this aspect."

"A ton of one or two?! Fifty grams?" Tony shouted, "Is this too exaggerated?"

"No exaggeration or exaggeration." Zhao Yuyouran said: "The black iron is just the most basic one among the gold-stove treasure refining materials. There are iron mother, gold essence, Taibaijin essence, etc. The materials that the acquired metal shop belong to can be refined from steel, but this proportion is in this proportion." He smiled slightly: "That iron mother, one hundred tons of steel can be refined one or two. As for gold essence, a mine should be able to extract a few taels, and Taibaijin essence..."

He shook his head and said nothing.

Tony opened his mouth: "Okay, I know, Master, did you let me go this way because I have money? Ordinary people don't have this capital, right?"

"Maybe."
