Zhang Lei sat on the stairs at the door, took out the wooden box given by Gu Tiande, and the irregular metal ores. I opened the wooden box and pinched it with my hand, the slightly soft yellow metal, the strength of this metal was too low, and it would be directly torn apart by the spatial fluctuations. The whitish iron ore was strong enough, but unfortunately it was not refined, and there was a lot of sand and gravel mixed in it, and even some other metals mixed together.

Slightly injected some energy into the two, and tested it, the energy transmission speed of this yellow soft metal is hundreds of times that of the refined iron ore. It seems that the two are going to be mixed together to make a shoddy alloy.

He took out the crimson flying sword that had just arrived from the storage bag, and cut the ore with some effort, roughly cleaning out the sand and gravel and other debris in the ore. It took about half an hour to cut all the ore. In the middle of the piece of ore, there are some yellow soft metals that are also sliced, and then in the weapon of the storage bag, find a hammer and beat it.

Laboriously pounded the ground into a small hole, and the refined iron ore still did not appear to be bonded to the soft yellow metal. Zhang Lei grabbed the back of his head, threw the hammer into the storage bag, put away the metal fragments on the ground, and walked towards the round gate in front of him.

A few steps to the round metal door, Zhang Lei stretched out a hand, stuck to the door, injected energy slightly, and then beckoned, the metal door turned into a small piece of iron and came to Zhang Lei's hand.

Putting away the metal door, Zhang Lei looked at the direction of the main house, and then a white mist came out of his body and took him to the sky, and quickly came to a place about 100 meters above the ground. Zhang Lei turned his head to look around, and then flew towards a small forest behind him.

Flying into this small forest in a few seconds, Zhang Lei put away the aircraft, then took out an irregular metal block from the storage bag, injected energy and threw it to the ground, "bang" a soft sound, and the five- or six-meter-high thorn puppet stood obediently in front of Zhang Lei.

found a relatively flat place, enlarged the metal door, placed it flat on the ground, and then piled up the metal pieces indiscriminately, took out the hammer and handed it to the puppet, and then Zhang Lei covered his ears and ordered the puppet to start beating the metal pieces.

After ping pong for a while, Zhang Lei ordered the puppet to stop, then walked over, turned over, and then ordered the puppet to continue beating. After beating this repeatedly for about an hour, the ore and the soft metal had been beaten into a thin sheet of metal that fused together.

After a simple test of the strength and energy flow speed of this simple alloy, Zhang Lei took out the crimson flying sword and began to cut the metal pieces into metal wires one by one for later use.

He took out some wooden products from the storage bag on his body and began to carve some parts of various shapes with his crimson flying sword. It took about half an hour to finally carve all the parts and start to add those alloy wires to put them together.

After roughly calculating the size of his head, more than ten minutes later, a small hat composed of various woods and some metal wires was assembled by Zhang Lei. After abandoning the energy supply system, this little hat is the simplest signal transmitter that Zhang Lei came up with.

Touching the slightly rough wooden hat with satisfaction, Zhang Lei looked around, and then put the small hat on his head a little impatiently. Close your eyes and mobilize the energy in your eyebrows to slowly recharge the hat, and then start to communicate with the shuttle in your head.

A slight buzzing sound began to sound in Zhang Lei's brain, the shuttle vibrated slightly, and then Zhang Lei felt that something seemed to be slowly peeled off in his head, and then the stripped thing was injected into the simple signal transmitter worn on his head, and then the hat on his head began to heat up slightly. Zhang Lei felt that the surrounding picture began to shake slightly, and then some kind of unique space signal was launched by the hat in the direction of the sky.

"Smack, smack. The sound of wood products shattering sounded softly, Zhang Lei hurriedly took off the hat on his head with several cracks, looked at the main body that was almost completely cracked, and then threw it into the storage bag. Zhang Lei exhaled a long breath, this positioning signal was finally launched, and the rest was left to wait, if within twenty-four hours, the Federation Development Fleet did not contact Zhang Lei through the shuttle in Zhang Lei's head, it means that the signal was not received by the Federation.

In that case, Zhang Lei will have to consider making some higher power signal transmission. The materials required for a high-frequency transmitter and the energy required to activate the transmitter are not a simple matter.

"Knock knock" Three dull bells rang suddenly, and this bell reminded Zhang Lei of the bell he heard in the square when he first came to Guiyuanzong. With the sound of the bell, several rainbow lights of various colors appeared in Zhang Lei's sight, and they quickly flew up from the nearby peaks and flew towards the direction of the main peak.

In the blue sky overhead, several huge strange artifacts like mountain peaks suddenly appeared, those artifacts slightly emitted a light purple flowing light, running autonomously in the sky according to some mysterious trajectory, and some purple lines slowly appeared in the empty sky, writhing like some kind of snake, and then a translucent purple light mask appeared in the sky, shrouding the entire Guiyuan Sect below.

Immediately after that, the whole air slammed down, as if something suddenly pressed on people's heads, and something like a small volumetric flask was suspended at the top of the light mask, slowly rotating, and with the rotation of round turquoise energy ripples, radiating from its bottom. The ripples are like a scanner, constantly sweeping over the peaks without dead ends.

Zhang Lei's Zongmen token in the storage bag suddenly ran out automatically, and voluntarily released a slightly white beam of light, which shone towards Zhang Lei's eyebrows. With the irradiation of this beam, Zhang Lei felt the heaviness of being suppressed by something suddenly disappear. Is there still a friend or foe identification system, Zhang Lei was a little stunned and caught the fallen token, and threw it into the storage bag casually.

It seems that something big has happened, and it can't have anything to do with the signal just sent, this civilization can use space jumping devices, then they are likely to be able to detect this space signal.

Zhang Lei quickly put away the metal door and puppet on the ground, set up the cloud and mist aircraft, and flew back to the courtyard at a low altitude as fast as possible. In a panic, he installed the door, then settled down, ran into the room lightly, and then calmly sat down next to the cheap master, closed his eyes and made a cultivation form.
