Sending away the guards who made him feel a little pressure, Zhang Lei hurriedly returned to the cave mansion, explained to Shen Bin and Shen Long, and after receiving the silver-clothed envoy who sent the materials later, Zhang Lei went directly into the refining room, found out the materials and the jade Ding furnace, and began to refine the refining furnace again.

Because of his previous experience, Zhang Lei decisively added an energy purification supply function to this new refining furnace, and then began to refine without hearing anything outside the window. However, when Zhang Lei urged the energy in his body to form a high-temperature flame, an accident occurred.

At the center of the eyebrows, the golden red token inherited by the great grandmaster, when Zhang Lei needed the refining flame, automatically split a golden-red energy filament from his body, integrated into Zhang Lei's true yuan, turned into a beam of golden-red flames, and drilled into the jade Ding furnace.

"Well, the temperature of this flame is really high enough. Zhang Lei looked at the rapidly melting metal block inside, frowned and muttered in a low voice.

Although he had the experience of the previous time, coupled with the golden red flame that was more suitable for refining, it still took Zhang Lei more than a day to refine this new version of the refining furnace. During this period, because of the high temperature of the golden red flame, the tattoo artist who was not used for a few days burned out once.

Trying to refine a part with a new furnace, I don't know if it added the energy purification function, or the relationship that incorporated some soul energy, Zhang Lei found that this new refining furnace seemed to be more handy to use.

Putting away the refining furnace, Zhang Lei opened the door of the refining room and said to Shen Bin, who was waiting there, "Did the silver-clothed envoy send those materials over?"

"Ahh Shen Bin was obviously a little uneasy just now, and suddenly saw Zhang Lei open the door and said in some surprise.

Zhang Lei nodded slightly, and then said, "You go and send those materials to me." ”

"Well, yes, my lord. Shen Bin secretly looked at Zhang Lei, and then hurriedly responded, turned around and ran outside.

Zhang Lei turned around and returned to his place, released the refining furnace again, and then sat down cross-legged, waiting for Shen Bin to send the raw materials over. In his spare time, Zhang Lei just let the shuttle instrument in his head calculate how big a space jump engine is needed to drive this huge fire refining sky. Without waiting for the wisdom brain in his head to estimate the answer, Shen Bin walked in from the outside with the stygian and each carrying a storage bag with a wooden plate.

"Lord, these materials are all sorted out, if you see if you need anything, the silver-clothed envoy said that you can let a few guards go to the treasury to collect them at any time. After Shen Bin put down these materials, he looked at Zhang Lei and said cautiously.

Zhang Lei nodded lightly and said, "I know, I need to find you again." ”

"It's the lord, the old slave went out first. Shen Bin opened his mouth, as if he wanted to ask something, but he looked at Zhang Lei's face staring at the ground material, secretly endured the question in his heart, and exhaled and said.

Zhang Lei waved his hand casually, and after the two left, he hurriedly closed the stone door, then poured out most of the materials, scanned them, and selected the materials for refining a super-large energy power furnace and seven engines according to this use.

Putting away the useless part of the materials on the ground, Zhang Lei threw the metal pieces one by one into the open refining furnace mouth, and then began to slowly refine the large Tianyuan crystal nucleus that used a three-dimensional rune structure.

With two refining experiences, coupled with this more advanced refining furnace and golden-red flames, it took Zhang Lei less than four hours to refine this Tianyuan Crystal Nucleus. After scanning around the Tianyuan Crystal Nucleus Energy Power Furnace, which was nearly ten times larger, Zhang Lei let the shuttle instrument in his head calculate that such an energy supply source can support the number of high-energy weapons.

After getting an approximate number, Zhang Lei put away the Tianyuan crystal nucleus, then sat down cross-legged, threw all the remaining engine materials into the refining furnace, and activated the automatic refining mode of the refining furnace.

Because of this engine, only some solidified rune arrays and some basic scaling arrays were added, so it only took Zhang Lei less than three hours for seven space jump engines of different sizes to be placed in front of him.

Looking at these engines with satisfaction and nodded, according to the data scanned just now, these engines from civilian technology are obviously much stronger than the short-range jump engines that Zhang Lei originally refined. Put away these engines, Zhang Lei opened the stone door, and then ignored Shen Bin, who bowed towards him, and Shen Long, who followed his footsteps, and went straight to the teleportation array of the small platform at the entrance of the cave, and communicated the golden red token in his head, and a burst of light flashed, and Zhang Lei came directly to the metal hall where the Tianyuan crystal nucleus was installed.

Nodding at the silver-clothed envoy who was sitting there cross-legged, Zhang Lei stepped forward to look at the Tianyuan crystal nucleus that had lost some energy, and then casually took out the giant Tianyuan crystal nucleus that was nearly ten times larger and placed it aside.

"This, this, this is what you refined?" The silver-clothed envoy was obviously startled by the huge Tianyuan crystal nucleus beside Zhang Lei, hurriedly took a few steps forward, looked at the huge jujube core-like object in front of him, and spoke.

"Yes, I just refined it, I have calculated it, and the vitality released by this thing is enough for this Fire Refining Heaven to use. Zhang Lei said as he communicated the golden red token in his head, and unloaded the small Tianyuan crystal nucleus in front of him.

Putting away the small Tianyuan crystal nucleus, without waiting for the light on the surrounding metal walls to dim, Zhang Lei hurriedly lifted the large Tianyuan crystal nucleus and placed it in its place. The large Tianyuan crystal nucleus had just been placed, and along with the golden red token in his head, Zhang Lei could clearly perceive that a huge amount of energy was extracted by this metal hall and transported to all parts of the entire huge Fire Refining Heaven.

I sensed it, somewhere underground, there were more than 10,000 spirit treasures that were constantly absorbing this huge energy. Zhang Lei secretly swallowed his saliva, since he knew the immortal weapon energy level, Zhang Lei had secretly imagined in his head what kind of power would be the strongest weapon of the immortal weapon level in the Federation.

"You, have you really refined this Tianyuan crystal nucleus?" The old man in Tsing Yi appeared in this metal hall at some point, looking at the giant jujube core not far away, and asked Zhang Lei with a complicated expression.

Retracting his thoughts, Zhang Lei nodded lightly and said, "Yes, I just refined it, with this thing, the defense power of our Fire Refining Heaven should be able to return to its original level." ”

"The future is terrifying, you are very good, the great grandmaster really didn't see the wrong person. The old man in Tsing Yi looked at Zhang Lei seriously, then sighed softly and said, then waved his sleeves and disappeared into a phantom.

Looking at the old man in Tsing Yi who suddenly appeared and disappeared suddenly, Zhang Lei pursed his lips, and then said to the silver-clothed envoy: "I have added a Gathering Yuan Array to this Tianyuan Crystal Nucleus, although there is vitality in the void that can be absorbed, but if you are free, you should add some crystals or spirit crystals to the Tianyuan Crystal Nucleus." ”

"Yes, Grand Master. The silver-clothed envoy bowed to Zhang Lei seriously and said.

Zhang Lei nodded, and then communicated the golden red token in his brain, and with a flash of light, he came to a place with a relatively thick body outside the Fire Refining Heaven. After looking around and finding that no one was paying attention here, Zhang Lei communicated with the golden red token and dismantled a piece of metal armor on the ground, revealing the magic circle passage inside. Taking out a small space jump engine, Zhang Lei adjusted the angle and carefully placed this special version of the auxiliary engine on the rune array.

After communicating with the golden red token and carefully testing the condition of the engine, Zhang Lei's figure flashed and appeared in another calculated position in the Fire Refining Heaven. With the assistance of this golden red token, Zhang Lei felt that this fire refining heaven was much more convenient than the battleship he refined, and after spending more than an hour, Zhang Lei, who had completed the installation of seven engines, flashed his figure and returned to the metal hall again.

Ignoring the silver-clothed envoy who stood up, Zhang Lei communicated, it was more like the golden red token of the antique-level wisdom brain, turning the walls on all four sides into transparent, and then on the star map reserved in the token, he found a barren coordinate, ran the seven engines, and turned on the jump mode.

Huge energy fluctuations spread, and the space on all sides of the Fire Refining Heaven swayed and twisted like a folded broken mirror. The familiar space jumping scene made Zhang Lei smile slightly, then looked at the new star field, and said to the silver-clothed envoy on the side: "Okay, those people should not be able to find this place at all, and after a while, I will refine those weapons, and we will seek revenge on them." ”

"Have you transformed the Fire Refining Heaven Realm Shifting Great Array?" The silver-clothed envoy looked at the Tianyuan crystal nucleus behind him that was still flashing with a charming light, then looked at the unfamiliar starry sky in the outside world, and then asked Zhang Lei.

"That's right, the original teleportation circle consumed too much energy, I changed it, and we can teleport at will. Okay, I'll go back to the cave first and refine those weapons. Zhang Lei said with a slight smile.

The silver-clothed envoy bowed, and then said slowly, "Congratulations to the Great Grandmaster." ”

Touching his nose, Zhang Lei felt a little uncomfortable with the sudden respectful attitude of the silver-clothed envoy, shook his head helplessly, and then communicated the golden and red token, and the figure flashed and appeared on the small platform in front of his cave.

Seems to enjoy this fast way of traveling, Zhang Lei turned around with a slight smile and walked towards the cave, no, just looking at the entrance of the cave, I don't know why Shen Bin, who kept pacing back and forth, so he asked: "Shen Bin, what's wrong with you?"

"Uh, Venerable Lord, have you really become the Great Grandmaster of the Fire Refining Heavens?" Shen Bin bowed to Zhang Lei, then hesitated slightly, and asked cautiously.

Frowning slightly, Zhang Lei opened his mouth and continued to ask, "Yes, is there any problem?"

"Someone sent a message to the old slave, saying that there are a large number of master-level refiners, and because they are not satisfied with you sitting in this position, they want to leave the Fire Refining Heaven. Seeing Zhang Lei frowning, Shen Bin hurriedly spoke.
