Looking at the five people parked on the platform in front of him, Zhang Lei flicked the gray dot in his head, only to see that the stygian in front of him suddenly collapsed like a robot that had been drained of energy. Seeing this scene, the other four guards' fingers trembled slightly, and then hurriedly walked away a few steps, revealing the collapsed Styka.

Zhang Lei frowned, and explained: "There was a person who assassinated me yesterday, I asked Styx to deal with it, and today this person appears in front of me again, you help me ask him what's going on." ”

"Please rest assured, although there have been no traitors in the Fire Refining Heaven for many years, we have always retained many means to deal with traitors. The eyes of the four guards released a cold light in unison, and then the underworld took a step forward, bowed, and said slowly towards Zhang Lei.

Zhang Lei nodded and said, "This traitor may not be him, but let's ask first." ”

"Yes, my lord, we will ask you clearly. After speaking, the underworld squatted down, touched the body of the underworld for a while, found a storage ring, handed it to Zhang Lei and said: "This is the auction material for the Xuangong Field given to you by the great grandmaster, by the way, let you refine some self-defense equipment, according to the great grandmaster, the fire refining heaven will not be peaceful recently." ”

"Oh? I see. In addition, there is a demon cultivator who claims to be the Demon God King just left here, so you guys go to someone by the way and report to the person in charge of this matter in the Fire Refining Heaven. Zhang Lei casually took the storage ring, and then said to the underworld.

"Yes, Lord. The four of them looked at each other, and then the youngest Ying Yi bowed towards Zhang Lei, turned around and disappeared in a flash.

Zhang Lei picked up the storage ring, looked into it, frowned, and asked, "Why are there so few? Didn't you say that there were 300,000 materials for the flying boat?"

"Well, this, it should be that the Great Grandmaster has exchanged all the low-level materials for high-level materials of the same value according to the rules. The underworld paused for a moment, then explained.

Zhang Lei glanced at the underworld, then took out a piece of metal material inside, scanned it with a scanning beam, and found that the properties of this material were indeed higher than those he had used before.

Nodding slightly, Zhang Lei raised his head and asked towards the underworld, "Then I want low-level materials, where do I go to buy them?"

"You don't need to buy it, you are now promoted to Grandmaster, and you can use your identity token to go to the treasury and withdraw low-level materials for an unlimited amount. The underworld explained.

Seeing this good thing, Zhang Lei smiled slightly and asked, "Then where is the warehouse?" I'll go find some materials first. ”

"Well, you don't need to bother yourself to come forward for this kind of trivial matter, you can say how many materials you need, and then give the token to your subordinates, and your subordinates can get the materials for you. The underworld explained casually.

Zhang Lei took out the identity token from the storage ring, handed it over to the underworld and said, "Can you withdraw as much as you want?"

"Yes, this is the special treatment that Fire Refining Heaven has for Grandmasters. The underworld took the token with both hands and nodded.

"Then extract 100,000 copies of the materials for the flying boat for me, and if anyone asks, you can say that it is an order from the Grand Master. Zhang Lei nodded and spoke.

Hearing the two terms 100,000 copies and the Great Grandmaster, Na Shenlu was stunned for a moment, and then nodded hurriedly and said, "Yes, my subordinates will go and extract materials for you." ”

Seeing that the underworld was far away, Zhang Lei put away the shield activator at the entrance of the cave and let in the three people who were blocked from the outside world. Looking at the three people who naturally passed through the shield of the cave, Zhang Lei asked the underworld walking behind in confusion: "Huh, can you walk in directly without the certification of this cave?"

"Lord Honor, after your subordinates sacrifice the Soul Control Heart Core, the identity token is automatically bound to your identity token, so you don't need to authenticate the identity token. The underworld man bowed slightly.

"Well, alright, you go and ask what the hell is going on. Zhang Lei waved his hand at the two people who were carrying the stygian and said.

Seeing the two of them enter a room close to the entrance of the cave, Zhang Lei was about to go back to the refining room to sort out the high-grade materials given by these great masters, at this time, the figure flashed, and the original leaving of the underworld suddenly returned to the cave, bowed respectfully to Zhang Lei and said: "Lord Qiqi, my subordinates have searched around and have not found the golden-clothed envoy." ”

"The Golden Clothed Envoy, are you saying that the Golden Clothed Envoy is responsible for such a thing as Fire Refining Heaven?" Zhang Lei frowned and asked.

Na Ying Yi nodded and spoke, "Yes, the Lord of the Golden Cloak is responsible for all the internal defenses of our Fire Refining Heaven. ”

"Then you go find the Grand Master, explain to him about the matter here, and by the way, our cave has been attacked by two waves of people today, one of which has assassinated me and was escorted to the Golden Messenger by Hades. Zhang Lei thought for a moment and said.

Na Ying Yi was stunned for a moment, and then said with some hesitation: "Well, this, at this time, the Great Grandmaster should not have time to meet his subordinates." ”

"It's okay, you go and wait there, the Great Grandmaster will always be free. Zhang Lei waved his hand casually and said.

Na Ying Yi bowed helplessly and said, "Yes, Venerable Lord." ”

Seeing Shen Yi leave again, Zhang Lei returned to the refining room, took out all the various materials brought by the great grandmaster, and looked at them in the same way, and found that although these materials were not much, they were enough to be used on the main battleship or the miniature planetary fortress.

With these materials, Zhang Lei's heart was completely restless, after all, the multi-layer protection mechanism of the star-shaped fortress was not something that could be easily broken by the existing force of this civilization. Coupled with the full version of the fortress cannon and various antimatter weapons that the planetary fortress has, even the monster besieging the fire refining sky may not be able to withstand a few shells.

However, the control of this planetary fortress is too troublesome, and there are many key positions that cannot be controlled with an auxiliary brain. If the main battleship is built, after seeing these monks who are above the integration period, Zhang Lei feels that the protection is a little insufficient.

rummaged through the refining information provided by the Zhizhi brain in his head, and in terms of appearance, Zhang Lei fell in love with a wealthy man's private customized travel UFO. Not to mention the beautiful enough appearance design, first of all, this thing is huge enough to directly arrange the multi-layer protection system of the planetary fortress on it, and secondly, the weapon fan is rich, and there are enough hidden gun ports installed on it, and it should be enough to deal with the general scene in terms of firepower.

The most important thing is that this aircraft, which is labeled as civilian technology, is equipped with a space jump engine that surpasses the engine of the main battleship. It may be precisely because this aircraft is marked as civilian technology that it escaped the eyes of a certain reviewer, and the complete design of this aircraft has not been erased from the database of the shuttle.

"Lord, I beg to see you on the underworld. Just when Zhang Lei was thinking about how to transform this luxury civilian aircraft, the underworld who went to extract materials and came back shouted outside the door.

Zhang Lei ordered the shuttle instrument to come up with a few transformation plans for himself, and then waved his hand to open the stone door of the refining room, and said, "Come in." ”

I saw Na Hell Road walk in with a large wooden tray and a large pile of storage bags. Placing the storage bag not far in front of Zhang Lei, Na Shenlu bowed down, handed Zhang Lei's identity token over first, and said: "Lord, there are too many materials, and my subordinates have to divide them many times before they can get them, please forgive me." ”

"It's okay, you take it slowly. Zhang Lei stepped forward and put away the identity token casually, then took a storage bag and looked at it, and said with a slight smile.

The underworld bowed again and said, "That subordinate has retired first." ”

"Okay, let's go. Zhang Lei looked at the metal materials in the storage bag, waved his hand casually and said.

Sorting all kinds of metals according to their usefulness, Zhang Lei was about to continue to study the design drawings, and the underworld road that had just left ran in again. Zhang Lei frowned and asked, "What's wrong?"

"No, no, the Grand Master asks to see. The underworld hurriedly shook his hand and spoke.

"Well, what are you waiting for, please let him in. Zhang Lei looked at this inflexible guy helplessly and said.

"Yes, yes, my subordinates will go. The underworld bowed, and hurriedly ran out again.

After a while, the figure flashed, and the great grandmaster appeared in front of Zhang Lei with a somewhat gloomy face, looked at a large pile of storage bags in front of Zhang Lei, and the great grandmaster said: "Little guy, put down your order first, there are some things that need your help to refine." ”

"Oh, what's it?" Zhang Lei stood up and asked.

The great grandmaster took out a jade slip and a storage ring and handed them over, and said: "This is the drawing and refining precautions, and the materials will be given to you first, you take a good look at it tonight, and tomorrow I will ask someone to inform you to go to the spirit space to refine together." ”

"Uh, I'll just refine it here, why do you want to go there to refine it?" Zhang Lei casually took the ring and storage bag and asked.

Glancing at this kid who didn't know the height of the sky, the great master slowly explained: "This refining thing is a little different, it can't be refined in ordinary places, you take a good look at the refining method, and you will know it tomorrow." ”

"Oh, okay. Zhang Lei nodded casually, it should be the way.

Looking at the underworld path on the side, the great grandmaster continued: "I know about the golden clothes, although I don't know why he betrayed the Fire Refining Heaven, but sooner or later I will find him out and give you an explanation." Let that guard of yours ask and let him go, as far as I know, he did hand over the assassin to the Golden Coat. ”

"Well, then I'll go and put the stygian in a moment. Zhang Lei frowned, nodded and said.

"Also, tonight, no matter what happens, don't leave this cave mansion, if someone comes to the door, let these guards solve it, understand?" Seeing Zhang Lei nodding, the great master paused, and then said with a solemn face.

Is there anything going to happen this night? Zhang Lei thought about the defense of his cave mansion, then nodded again, and said, "Understood." ”

glanced at Zhang Lei again, and the great grandmaster flicked his sleeves and disappeared into a phantom. Seeing the great grandmaster leave, Zhang Lei turned his head to the underworld and said, "Since there is no problem with the underworld, you go and let him go, and then call a few to help you move all the materials back." ”

"Yes, Lord. Hades bowed and said, and then retreated.

Seeing that the underworld was leaving, Zhang Lei hesitated for a moment, and did not continue to pack up the materials, but turned his head and released the refining furnace, threw some materials into it, refined a few small intelligent identifiers, and then took out the shield generator that he had put away and walked towards the outside of the cave.

The double-linked shield was activated again, Zhang Lei shouted to Shen Bin who was showing his head on the side, gave him the smart identifiers, and asked him to wait at the door, then turned around and returned to the refining room, found the jade slip given by the great grandmaster and looked at it seriously.

"Huh, why does this finished product look so much like an energy-powered furnace? Zhang Lei looked at the jade Jane, closed his eyes in the brain database in his head, found out the energy power furnace of the Federation, made a comparison, and then muttered in a low voice.

"This should be a semi-finished product, it seems that the people here still have some research on energy power, but I don't know why they haven't continued to study. After carefully reading the details, Zhang Lei said to himself.

"Knock knock!" A knock sounded on the door, disrupting Zhang Lei's train of thought. Frowning, Zhang Lei waved his hand to open the stone door, looked at Shen Bin at the door and asked, "What's the matter?" Didn't you let you watch at the door?"
