After taking a large amount of calcium carbide in a big bag by the river outside the village, Han Zi couldn't wait to return home.

Han Zi took out a calcium storage carbide from his pocket, looking at the black calcium storage carbide, Han Zi thought in his heart how to successfully apply the current in the calcium storage carbide to practice.

After repeated thinking in his brain, soon Han Zi had an idea in his heart, Han Zi used the spiritual power in his body to create a hole only the size of a needle and thread in the center of the calcium carbide, and then got up and went to the waste recycling point in the village, ignoring the boss's eyes like looking at a fool, and spent ten copper plates to buy back a bunch of broken bronze tools.

After Han Zi returned home with this pile of waste bronzes, he took out a square bronze tripod half a meter high from the brass ring left by his mother.

The four sides of the cyan copper tripod are erected with four antennae, surrounding the pattern veins of the tripod body, adding a beautiful atmosphere to the bronze tripod!

"This must be the alchemy used in the immortal cultivation world, right?"

Han Zi guessed in his heart.

After the bronze tripod was placed, he took out a spiritual fire talisman and placed it in the fire path of the tripod to urge the spiritual power to activate the spiritual fire talisman, and soon the flames in the fire path were burning.

Han Zi put a pile of scrap bronze ware he bought into the bronze tripod and prepared to refine it into copper liquid.

If there is a monk here, he will definitely angrily scold Han Zi for being a loser, and the high-level alchemy tripod in the immortal cultivation world was actually used by Han Zi to refine a pile of scrap copper and iron.

In less than an hour, the dilapidated bronze in the ding has been completely refined into liquid, Han Zi used his spiritual power to make the copper liquid in the ding into copper wires like hair, after carefully making thousands of copper wires, due to the excessive use of aura, Han Zi's energy was a little prostration.

Han Zi took out a Hui Qi Pill from the Yellow Ring and swallowed it, sat cross-legged on the edge of the Ding, the Hui Qi Pill turned into a large amount of aura and entered Han Zi's body, replenishing the overused spiritual power, two hours later, Han Zi's whole body aura returned to its best state, and he stood up full of energy.

Looking at the hair-like copper wires she made, she was very happy in her heart, with these copper wires, she was able to make full use of the current in the calcium carbide.

Use your divine sense to connect the copper wire into the hole created by your spiritual power, and a trace of electricity flows out along the copper wire, emitting a nourishment... Zi sounded.

Han Zi took out some jade that was not of much value from the yellow ring, as well as the titanium wire that he had prepared a long time ago, the titanium wire can bear the high temperature generated by the current, when the high temperature reaches a certain height, it will form a bright light, and then achieve illumination, polish the jade into a lamp-shaped shape with aura, put the titanium wire into the reserved wire groove, and then Han Zi will make the copper wire into a live wire respectively, and after the two wires of the bright wire are connected separately, the two wires will be connected to the calcium storage carbide according to the steps.

At the moment of accessing the calcium carbide, the white jade lamp instantly emitted a bright light, and the first electric lamp in the other world was born.

"It worked!"

Although it was just a simple electric lamp, Han Zi's heart was still very excited.

Then Han Zi spent another afternoon making six electric lights one after another.

Since there is no such thing as plastic in this world, Han Zi can only put a gray cloth twist rope at the interface of the calcium storage carbide as a light switch.

This reminded Han Zi of the scene in the countryside before his previous life (note: in the 90s, most families in the countryside used a rope as a light bulb switch).

When Han Zi was seriously making electric lights, Yuanyuan came once during the period, and when he saw Han Zi tinkering with these messy things, he muttered in confusion: Sister Zi doesn't look so funny, I look like you're still having fun.

"Hey, hey. ”

Han Zi smiled at Yuanyuan, and pulled the cloth rope with his hand, and the electric light immediately turned on, which made Yuanyuan very surprised.

Looking at Yuanyuan's surprised expression, Han Zi explained: This is called electric light, which is used for lighting at night.

"Oh. Although Yuanyuan didn't know what an electric light was, he nodded his little head and sighed.

Seeing this, Han Zi wanted to laugh in her heart, and gently pinched her round fleshy face.

"Sister, you're pinching someone's face again. ”

Yuan Yuan vented the dissatisfaction in his heart, and his nose and mouth were upturned.

"Haha!"

Seeing this scene, Han Zi finally couldn't resist the urge to laugh in her heart and laughed out loud.

"My sister is so bad!"

After Yuan Yuan finished speaking, he grimaced at Han Zi.

In order to compensate for the behavior that made you angry, my sister is going to send you an electric light. ”

"Really!" said Yuanyuan happily. ”

"When did my sister lie to you, come over and my sister will teach you how to use it. ”

After teaching Yuan Yuan hand in hand for a while, Yuan Yuan happily took the electric light given by Han Zi and left.

After Yuanyuan left, Han Zi stretched lazily, got up and went back to his bedroom, and fell asleep in the quilt.

However, at this time, the immortal cultivation world was chaotic, and the Eastern Regions forces led by Tianwu Sect brazenly launched wars against several other domains, the cause of this war between monks was ostensibly because Zhu Ran, the peak master of the Sword Peak of Tianwu Sect, was wanted by the Immortal Cultivation Alliance, which led to Tianwu Sect's announcement of its withdrawal from the Immortal Cultivation Alliance, but in fact, the ancestor of Tianwu Sect successfully broke through the god transformation period and won the first major sect in the Apocalypse Continent, throwing away the shackles of the Immortal Cultivation Alliance, and Tianwu Sect strongly annexed the surrounding small and medium-sized forces, which also caused a strong rebound of other big forces, and the war was about to break out, and the great sects of Immortal Cultivation in other domains formed an alliance army to jointly resist the attack of Tianwu Sect。

In the Cloud Mist Mountains at the junction of the Eastern and Central Regions, a fierce battle is taking place at this moment!

The army of monks of the Heavenly Martial Sect is besieging the second largest sect in the Heavenly Apocalypse Continent at the moment with all their might, the Huayang Sect station, the air and the ground are attacking at the same time, all kinds of spells and magic weapons are raining down towards the Huayang Sect's Protector Array, and under the fierce attack of the rain-like spells, the light of the Protector Sect Array quickly dimmed.

In the sky above the Cloud Mist Mountain Range, the Heavenly Martial Sect Ancestor was sitting cross-legged in the clouds at this moment, and on either side of him stood the Heavenly Martial Sect Sect Master and a group of Heavenly Martial Sect Elders.

"Ancestor, as long as the Great Protector Sect Array is broken, the Huayang Sect will be at your fingertips!"

At this time, the Sect Master of the Heavenly Martial Sect suddenly turned his head to the Ancestor of the Heavenly Martial Sect and said with flattering words.

"Yes, Ancestor, as long as the Huayang Sect is broken, there will be no obstacle for us to enter the Central Domain, and your image will be with the sun and the moon at that time!"

After speaking, the Great Elder of the Heavenly Martial Sect also bowed to the Old Ancestor of the Heavenly Martial Sect.

The behavior of the Great Elder made the sect master and the elders on the side boast in their hearts, and they despised him very much, they had seen people who praised people, but they had never seen such a high praise, you praised the old guy like this, and the old guy might not buy it, of course, this is what they said in their hearts, even if they were killed, they didn't dare to say it.

"Yes, yes, if it weren't for the wise leadership of the Ancestor, how could we have made such rapid progress, with the Ancestor leading us forward, my Tianwu Sect will definitely be able to win the eight directions!"

The words of the elders of the Heavenly Martial Sect rang out one after another. Nonsense: Old monsters like them, who have lived for an unknown number of years, if they don't know how to stammer people, how can they climb to the heights they are today.

However, the ancestor of the Tianwu Sect didn't pay attention to them on the surface, but sighed in his heart, it seemed that his Tianwu Sect didn't have much to do, look at his group of disciples and disciples, all of them were all virtuous, except for flattery, he doubted that they would do something else.

"Suddenly!"

The Divine Consciousness of the Heavenly Martial Sect Ancestor found a breath at this moment, and he knew that it was the breath that was about to break through the Transformation Stage.

Sure enough, as the ancestor of the Heavenly Martial Sect expected!

Only a quarter of an hour later, a loud bang was heard in the sky.

The ancestor of the Tianwu Sect shook his head in disappointment, the sect master of the Tianwu Sect saw the strangeness of his ancestor, and he didn't know what was going on, and was about to ask, when he heard the ancestor shouting in the direction of the Huayang Sect in the distance: "Congratulations to Senior Sister Yulian for advancing to the gods, Senior Brother is here to congratulate!"

"Hmph, dead old ghost, you attack my Huayang Sect's hatred today, we will settle it in one day, although you have achieved the transformation of gods, but don't forget, my longevity will be a long longer than you. ”

The cold warning sound from the direction of Huayang Sect made the Heavenly Martial Sect Ancestor's body tremble, and he raised his head and sighed to the sky!

He knew that the dream of the Heavenly Martial Sect to march into the Central Domain and unify the Heavenly Apocalypse Continent was shattered, so he waved his hand and ordered all the disciples of the Heavenly Martial Sect to immediately retreat and return to the sect.

Han Zi slept for a day and a night, and when she woke up, it was already the evening of the next day, Han Zi casually made a little food in the kitchen, and threw herself into cultivation, in her words, cultivation and science must be carried out at the same time, and neither can be branded.
