Li Yao smiled and said, "It's nothing, it's just a useless potion. It's just a thank you as a golden puppet. It's worthless, it's just a heart."

Of course, Miller knew what was inside the test tube and was happy. As expected, there was no vain investment. The blood of the ancient god is not something that can be obtained casually.

Although it is only the blood of the ancient gods of a low level, the divine substances contained in it are widely used and are good things that are priceless.

How could this kind of thing be a valuable thing? And it seems that the test tube is quite large, so there are so many that it shows sincerity.

"You're welcome, you're welcome." Miller smiled and put away the blood of the ancient god. How could he refuse such a thing? Otherwise, even if it is circulated in the future, it will inevitably be obtained by people of the great craftsman level.

Although his status in the clan is not low, the blood of the ancient god cannot be quenched at all. Seeing Li Yao like this, Miller's smile became a little friendly. No matter what, this master is still very good to him, and he is grateful to him and is a person who can make friends with him.

The two of them smiled tacitly. Li Yao took out two chips and said, "These are two chips I got, but the third portal was occupied by the ancient god. After killing the ancient god, the combat power was severely damaged, so he came back and did not look for the lower four."

"It's enough, it's already a great blessing to destroy the ancient god's plan. I heard that it was because of the master who exposed the ancient god's conspiracy, and the master used a strategy to trick those timid goblins into it and killed the ancient god. Otherwise, if the ancient god was given time to develop, the consequences would be unpredictable." Miller ended up putting the chip into a machine.

"It's just a lucky chance, it's just a coincidence. After all, it's a big deal for the ancient god to break through the seal of the Titan, and it's worth taking some danger. As long as the superiors don't make many masters sacrifice because I'm not making a decision without authorization."

"The master is humble. There is no way to sacrifice fighting the ancient gods. I believe that those sacrificed tribe members died in battle because of the ancient gods, and their souls will also be resting." Miller changed the topic and said, "These two chips are still masters. I only need a little time to copy the things inside, it only takes a quarter of an hour."

"That's a problem. I also want to study Titan's technology and language." Li Yao said with a smile.

"Master is kidding. You can unlock the three most difficult portals in a row, which shows the master's background. I also want the master to give guidance to Titans and the ancient gods." Miller opened another door: "Master, please come in. This is my collection room. Although it is a bit simple, it is also my hard work. The master can choose three items."

Li Yao glanced at him roughly and found that there was obviously his private laboratory, with a lot of things inside.

Materials, drawings, potions, and gems are not good, but not many of them are truly high-quality. Li Yao knew in his heart that his good things must have been put away long ago.

However, he was already very satisfied with seeing these Li Yao. Even if the high-end things are too good, he wouldn't be able to use them now.

Moreover, as a rebirth, he has some means to get good things. Now the most important thing is a tank-shaped mechanical puppet, and the others are some auxiliary things.

"This laboratory is really good." Li Yao said while looking.

"Don't the master want to settle here? I specially arranged a spacious residence for the master, which also has a laboratory. If it is perfected, it will definitely not be worse than mine." Miller obviously wanted to make friends with Li Yao: "Even if the master chooses, if he is really not satisfied, I also store some things in the warehouse, which can always satisfy the master."

Li Yao finally walked to the drawings and said, "It's enough, enough. After all, I can't control the things that are too high-end."

"I have learned these drawings myself, and some of them were drawn by myself, and the masters should be able to use them." Miller was not surprised at all when he saw Li Yao looking at the drawings at the end. For them, drawings are the first priority, and if he were also going to choose drawings.

"This..." Li Yao took out a drawing.

"The basic structure of mechanical puppets. It seems that the master is preparing to be a mechanical puppet for himself." Miller said: "This is good. Although the master is not strong enough now, he will definitely use it after a while. Now he has learned it very practical."

The so-called puppet basic structure drawings are made of some fragmentary components and lines. After learning, they have a lot of effect on Li Yao's mechanical pet production. They are very practical and passively blessed engineering drawings.

"Then I will choose this one for the second one." Li Yao said happily. He didn't expect Miller to put this drawing in it for him to choose.

"The master really knows how to choose. I'll just do this one. Although the level is not high, it can only be drawn by a master or above. With this, plus the master's mental power, it's really awesome." Miller complimented.

"Where, I'm used to being alone and don't want an assistant, so I have to use this." Li Yao made a random excuse. In fact, the dark camp did not have such drawings at all.

Those goblins would rather use a large number of low-level engineers than use such high-precision equipment. After all, they are all in the eyes of money. A copper plate is a big deal, let alone such a machine tool with great fraud.

"This is the case in Chapter 3." Li Yao took out the last drawing.

"Why did the master choose such a huge war machine?" Miller asked in confusion.

Li Yao put away the spider tank drawings and said, "My dream since childhood is like becoming a war engineering master, but I have never had the chance to learn how to make spider tanks and make up my wish. This drawing is very precious. If I don't work, I'll change it."

"Of course not, I also want to see the master make a spider tank."

"Haha, I'm looking forward to it too." Li Yao's excitement is not fake. Spider tank is a large war machine, and naturally it can also be changed to an intelligent machine.

Li Yao's original expectation was to find a mechanical war bear drawing and was satisfied. Unexpectedly, he found a mechanical tank. It has to be said that it was an unexpected surprise. Now Li Yao is already home and wants to return to his own laboratory in Undercity as soon as possible and collect materials to make it.

Li Yao walked out of the collection room and got the chip again. He couldn't wait to leave, so he refused to stay with Miller for dinner. Miller had to send someone to send Li Yao to the residence.

What disappointed Li Yao was that there was no land deed, otherwise this place would really belong to him. Li Yao knew that he was not completely relieved of himself, but he was no longer here and went straight to Hearthstone to return to the Underworld...
