Shen Bin stepped forward quickly, bowed respectfully to Zhang Lei, and then said, "Lord Qiqi, there is a young man outside the door, it is said that he has made an appointment with you, and he is still your old friend." ”

"After making an appointment, after returning the deceased, where did I come from, after the deceased, what is his name?" Zhang Lei frowned directly and asked.

Shen Bin shrank his head slightly, and then hurriedly replied: "His name is Ye Lele, it is said that he is Ye Tianlong's grandson and nephew, do you know a person named Ye Tianlong, if you don't know, the old slave will go and blow him away immediately." ”

"Ye Tianlong, it seems that the name of the bronze envoy is called this, he sent me a storage bag of refining materials, saying that the descendants of his lay family will come to me to beg me for errands. Since you're here, let's see him, you go and let him in, and by the way, call the guards, don't come to the door to assassinate him. Zhang Lei thought for a while, and then remembered the name from somewhere in his memory.

"Yes, yes, the old slave will let a few guards take the boy to the reception room. Shen Bin hurriedly bowed, and then ran out.

Zhang Lei reluctantly put away the jade slip in his hand, adjusted the shield activator on his waist, and then slowly walked towards the reception room near the gate of the cave. Before he could enter the reception room, a slightly slight-hearted young man's voice came out of the open door: "Hehe, don't be nervous, don't be nervous, seniors, the kid has just been promoted to Jindan, and Zhang Shi can't hurt him even if he stands there." Alas, alas, don't touch me, alas, that's enough, old man, you're only in the golden pill period, why do you treat me like this. ”

"What's going on?" Zhang Lei walked into the reception room and asked in a circle of people.

Shen Bin embarrassedly let go of the young man in front of him, then bowed down and replied, "Lord Honor, in order to prevent another assassin, the old slave wants to search this kid. ”

As soon as Shen Bin's words fell, the ragged young man in the center suddenly knelt down, crawled towards Zhang Lei, and shouted loudly: "Master, I can be regarded as seeing you, look at what your housekeeper has ruined me." ”

"You recognized the wrong person, I don't remember when I took in an apprentice. Zhang Lei frowned and said to the young man who was grabbed by the underworld.

The young man with a face that resembled some kind of cloven-hoofed animal struggled a few times, and after finding that he couldn't break free from the hand of the underdog, he was half-lying on his stomach and said to Zhang Lei: "It was the uncle who said that he could come here to ask the master for something, so the kid came here this time to ask the master to accept the boy." ”

"I don't accept apprentices, let's take him out. Zhang Lei glanced at the scoundrel-looking young man and said to the young man who had returned to normal.

Styx didn't reply, mentioned the young man, bypassed Shen Bin and was about to walk outside, at this time, the young man's face changed, and he shouted loudly again: "Master Zhang, wait a minute, the kid's uncle has fallen, only you can help the kid at this time, if you throw the kid out now, you can see the kid's body somewhere tomorrow." Please ask Master Zhang to see the face of his acquaintance with his uncle and accept the boy, even if it is a registered disciple. ”

"Wait, you said that the bronze coat has fallen?" Zhang Lei frowned, stopped the underbody, looked at the young man and asked.

The man who was carrying the back collar of the undertaki struggled slightly, and then spoke: "Yes, Uncle Zu was seriously injured some time ago, and he fell not long after he came back. Now many people are eyeing me who has been inherited by my uncle, and today's fire refining sky is in chaos, those people will definitely take advantage of today's action, please Zhang Shi accept the kid and save the kid's life. ”

"I don't take apprentices. Zhang Lei repeated these words, then thought for a moment, and said to the styx: "You will watch him tonight, and send him away tomorrow." ”

"Uh, thank you Master Zhang for taking me in. A look of regret flashed on the long-faced young man's face, and then he hurriedly spoke.

Zhang Lei waved his hand casually, then turned around and left the reception room, his head lowered, thinking about the energy power furnace composed of the rune magic circle in his head. This version of the power furnace, although it is too different from the power furnace of the Federation in terms of stability, but in terms of energy output explosiveness, it directly throws the technology version out of the way.

Closing the stone door of the refining room, Zhang Lei sat in front of the refining furnace, and finally understood why the great master said that this thing could not be refined in ordinary places. This version of the energy power furnace uses an explosive energy output method, and the general energy supply method cannot provide such a huge amount of energy in time, so this energy power furnace uses a dense rune array in its center to condense a large number of high-concentration energy gathering cores.

In order to ensure the concentration and purity of the energy absorbed by this power furnace, it was clearly required in the jade slip that this energy power furnace called Tianyuan Crystal Nucleus must be refined in a place where the concentration of free energy is high enough and pure enough.

"Such a fast energy output speed can improve the efficiency of the engine by more than 30 percent, but there is no energy knot technology here, and this high-concentration energy core will definitely explode in the end due to excessive load. If you can combine this energy node with the operation mechanism of the Federation Energy Power Furnace, then the finished product should have an amazing leap in data. Zhang Lei touched his chin, drew drawings with his brain in his head, and then whispered to himself.

It didn't take long for an energy power furnace blueprint that combined the rune array technology of the monk civilization and the core technology of the energy section of the scientific and technological civilization to form in Zhang Lei's mind. After reading the drawings carefully, Zhang Lei opened his mouth and said to the Zhi Brain in his head: "No. LSK1151, help me look at this design drawing, there is anything that can be improved." ”

"You can replace all the runes on this with three-dimensional runes. The mechanical voice of Zhi Brain sounded in Zhang Lei's head.

"Slap" Zhang Lei slapped his head, and then whispered to himself: "Yes, I forgot about this, if this is all replaced, then the model of this intermediate energy joint will also be improved, and the effect of the three-dimensional rune can be several times higher than that of this basic rune." ”

"Anyway, there are three copies of this material, so let's just refine both versions directly, and see what the specific parameter gap is. After Zhang Lei took out the materials, he grabbed his chin and thought about it slightly, and then said to himself.

After adjusting the parameters of the brain in the refining furnace, Zhang Lei carefully threw pieces of materials that flashed with faint brilliance into the furnace, and muttered in a low voice: "Luxury, waste, this natural high-energy polymeric metal should be used to refine offensive weapons such as fortress cannons, but it can't be used to refine engines." ”

After the refining furnace began to operate independently, Zhang Lei sat cross-legged and supported his chin with one hand, and began to make an idea in his heart, how to go to the fire refining heaven treasury full of treasures, and extract enough high-level materials to perfect his UFO car. After all, a fortress cannon made of ordinary metal can be several times different in power compared to a fortress cannon made of high-energy polymer metal.

The slight golden collision sound of "Ding, Ding, Ding!" woke Zhang Lei up from his fantasy, and when he looked up, he saw that the huge refining furnace began to shake slightly for some reason. hurriedly stepped forward, holding the refining furnace with one hand, injecting his own energy, intending to check the situation inside.

I didn't think that as soon as the energy was injected, it was sucked away by a suction force that came out of nowhere. Then Zhang Lei found that his hands, as if they were glued together by super glue, were tightly attached to the metal wall of the refining furnace.

The energy in the center of the eyebrows was uncontrollable, and it was sucked away by the refining furnace, Zhang Lei hurriedly used the remaining hand to take out the spirit crystal spirit stones on his body, crush them one by one, and then let the space in the center of the eyebrows automatically absorb it. Some panicked were attached to the refining furnace for more than an hour, Zhang Lei looked at the parts that were spit out by the refining furnace, exhaled deeply, and then sat down on the ground on the side.

"These things really have to be refined in a high-energy place, fortunately, it's just a part of refining with the basic rune array, if you learn the refining method in the jade slip, and directly use the three-dimensional rune array to refine a whole, then the whole person will be sucked dry today." Touching his faintly sweaty forehead, Zhang Lei muttered to himself in a low voice.

After looking down and thinking for a while, Zhang Lei found that the energy purification device that had been refined for the cheap master was very suitable for use in this place. After finding out the drawing parameters of the energy purification device, Zhang Lei directly doubled the size of the entire device in the refining furnace, and then threw it into the metal and began to refine it automatically.

Another hour later, Zhang Lei patted the doubled energy purification device with satisfaction, and then connected the energy output port to the refining furnace on the side. Putting in another high-energy polymeric metal, Zhang Lei turned on the automatic refining mode, and then secretly took two steps back.

I don't know if it was because of the sufficient energy supply, or because of this high concentration of energy supply, after waiting for less than half an hour, the mouth of the refining furnace shook slightly, and a part that flashed with brilliance was sprayed out by the refining furnace. After taking the part and looking it up and down, Zhang Lei stepped forward and put in another metal again and started the refining of the next part. One after another, Zhang Lei kept refining for another five or six hours before refining all the parts of this revised version of the Tianyuan Crystal Nucleus.

It took more than ten minutes to assemble it, and then Zhang Lei slowly circled around it, looked at the energy supply outlet above, Zhang Lei began to use the scanning beam, and kept scanning the specific parameters of the two-meter-high jujube nucleus device.

"Compared with the original Tian Yuan crystal nucleus, the energy output speed has increased by less than 10 percent, but the stability has increased by 500 percent. Compared with the Federal Tec version of the energy power furnace, the energy output speed has been increased by 306%, and the stability has decreased by 10%. Yes, yes, if you change to a three-dimensional rune circle, then there should be a big change in these data. Zhang Lei looked at the data provided by the brain in his head, nodded and muttered with satisfaction.

Putting this thing into the storage ring, Zhang Lei took out the materials and was about to refine the version of the three-dimensional rune array, when the stone door of the refining room was knocked on from the outside.

Putting down the metal block in his hand, Zhang Lei frowned and opened the stone door of the refining room, and asked Shen Bin, "What's wrong again?"

"Well, that, the kid you took in last night got you in some trouble. Looking at Zhang Lei's frowning brows, Shen Bin shrank his head slightly and spoke.
