Solid-state lighting has three gears, micro brightness, medium brightness, and high brightness. The merchant said that it can be bright for 4000 hours is according to the low brightness statement, and the advertising effect is the same in any era. However, if the brightness is adjusted to high, the solid-state lighting can also be used for a long time, at least hundreds of hours, and it is very durable.

Xu Zhi threw the lamp into his pocket, this thing is not big, the size of a flashlight, and the lamp head can be rotated three hundred and sixty degrees, which is very convenient.

"What are you doing again?"

The old green-skinned village chief squinted his eyes slightly, he had finally recovered recently, and he had eaten two breadfruits in one meal today, but there was no meat, and he missed the taste of meat very much, which made him a little dissatisfied. But happily, breadfruit tastes good when dipped in brine, and eating a big mouthful of breadfruit and drinking some brine is delicious, delicious, delicious, wonderful.

"There is a baby, come and see what good things you have in the village chief, if it is suitable, I will change it with you."

Xu Zhi squeezed his eyebrows at the old green skin, this old guy, he has been saving for sixty years, there must be something good, this time he doesn't pick out some blood, he still doesn't believe it. The first deal failed, and the second deal couldn't be pitted.

"Then take it out and see."

The old green skin opened his eyes, and he was still very interested in hearing the baby, these days, it is a pleasure to watch the baby, and there are so many entertainment activities for everyone, like humans can make people at night, what can the jungle goblin do, make straw sandals and straw hats for a night, or shiver in front of the campfire until they want to sleep.

You must know that the old green-skinned recorder is not easy to learn, and it took decades to play it well.

Looking at Xu Zhi's expression, and with a look of shame on his face, the old green skin became angry for a while.

"Lao Tzu didn't take advantage of you, Lao Tzu is the notes of the archmage, the real notes, good baby."

The eaves of the old green leather bed crackled, and he seemed to be very dissatisfied with Xu Zhi's big gains.

"Okay, good, you're right, is there a better baby, my baby is rare in our elemental world."

Xu Zhi snorted and said to the old green skin: "Don't give me the baby I can't use, the one I gave you last time can at least be eaten, and the one you gave me can't be used, and I can't look at it." ”

The old green skin rarely blushed, and his heart was sympathetic, if he could use it to study and understand, that thing would not be given to you, but it was useless to exchange it for you, or it wouldn't be so easy to change out because of greed.

"You tell me what kind of treasure you are first, and I'll see what I can exchange for in my treasure trove."

The old green leather stall stall spreads his hands, this is Xu Zhi came to the door to change, and the initiative is his.

"How about a good baby who can shine at night, can still turn on, can turn off, and can also dim the brightness."

Xu Zhi didn't take anything, and described it first.

"Hey, I didn't think you still had good things, whether it was a mining lamp made by an ancient goblin."

Old Greenskin was thoughtful.

Ai, there is also this kind of craft in this world, Xu Zhi was a little confused, he always thought that the world was very backward, fighting by fists, traveling by walking, and patrolling by Gege.

"Miner's lamp, what does it look like?"

Xu Zhi is still quite interested in this, so if he understands the world, he needs to ask.

"Isn't your baby so big, so tall, that it can be hung on the beams of the house, and the kind that the light can shine on?"

Old Greenskin kept making comparisons with his hands, he was naturally interested in the things made by ancient goblins, the goblin civilization is very remarkable, the ancient goblins are weak, but they have nearly the world's highest achievement technology, can go to the sky, can go to the ground, can dive, and the ancient goblin clan is really rich, it is the race that the old greenskin envies.

Of course, that race has slowly disappeared in the world with the years, and now it is difficult to find out where the ancient goblins lived, it is said that the red dwarves have obtained some goblin things, and the old green skin heart Xu Zhi This mining lamp should be from the red dwarf clan.

"I'm not that big."

Xu Zhi shook his head, such a big miner's lamp, is this going to be used as a searchlight or what, it can't blind people's eyes when it is lit.

"Could it be a detector light?"

The old greenskin wondered that the detection lights were much smaller, and the goblins liked to attach the detection lights to their hats and put them on the dwarves for mining, which worked very well.

Looking at the appearance of the old green skin, it is not much different from the solid-state lighting. It is said that the energy ore drive used by the detection lamp is a bit similar to an energy storage battery, Xu Zhi is speechless, in different worlds, sometimes similar products may appear when things come out.

"Pretty much."

After Xu Zhi finished speaking, he took out the solid-state lamp, turned on the dimming button, and suddenly the old greenskin room became brighter, which was much brighter than the fire that the old greenskin burned.

"Hey, this light is good, the brightness is just right."

The old greenskin stretched out his hand, Xu Zhi snorted twice, but he didn't refuse him, and let him take it.

"Let's talk about it first, if the baby you gave me can't be used, I won't exchange it for you, Da Da Mu heard that there are a lot of good things."

Xu Zhi didn't understand the rules, and the first time he took veal, he was taken advantage of by the old green skin, of course, it can also be seen that the old green skin thought that Xu Zhi was using things to buy a small official position and get out of this low-level position. In the end, the official position was given to Xu Zhi, and the old green skin suffered the bitter fruit, and Xu Zhi couldn't say who took advantage of it.

The second transaction, a bag of salt and a notebook on the relationship between five cents and a piece, the difference is not big, the old green skin is not a pit himself, why do you not believe in the old green skin, Xu Zhixin said, it is really strange.

"Click, click."

Old green leather rotary button, medium brightness, high brightness connection opens.

"me, blind my eyes."

The old green skin shook his hand and almost threw the solid-state lighting out, but fortunately, Xu Zhiyan was quick and grabbed it.

"I'll wipe it, village chief, you have to pay for this break."

Xu Zhi stared straight, he bought it back in twenty-five after all, and it was very valuable.

The old green skin looked embarrassed, no, it's really troublesome to break, whether to pay Xu Zhi or cheat, then it's really worrying, it's good if it's not bad.

"You suddenly light up so much, everyone will be startled, you have to show Da Da Mu, I guarantee that he will be scared and smashed."

The old green skin took the solid-state lighting again, and he couldn't put it down, in the era when there was no electric light, the temptation of a luminous body was obviously unimaginable to modern people.

Xu Zhi still remembers that in his previous life, his house was the first in the village to be electrified, but at that time, almost the whole village came, and looked at a luminous incandescent lamp for several hours, and was amazed, and that, it was still the oil lamp turned to the electric light, but there were no oil lamps in Dongfang Village, and the gaffe of the old green skin was also reasonable.

It was a memory that belonged to an era, and Xu Zhi thought that it was difficult for him to experience it again, but he didn't expect that in this dream world, he felt it.

"This little lamp is good, just for the house, the bigger one can be used for the bonfire, the place is bright, the biggest one we can use to fight wolves at night, those wolf cubs who get into the village can't run."

The old greenskin was very excited to prepare the use of solid-state lighting.

"What do I have to give you, you are good, you are good!"

The old green skin muttered, very troubled, Dongfang Village has a class, but there are also rules, there are no rules, there is no square circle, rewards and punishments are also inherited from ancient times, and social groups must abide by the civilization.

"You wait."

Old Greenskin took out a backpack, and Xu Zhi saw that the backpack was constantly filled with armor, staffs, wooden shields, axes, bows and arrows, and hammers...... A steady stream of things to take out.

Village Chief, are you in the pocket of a jingle robot cat?

Xu Zhi was stunned! What kind of black technology is this, there is no such thing in the real world.
