Chapter 538: The iron of the void, technology to help out!

In the bright sunshine, several children with broken clothes are playing on the grass. August 1st???? Chinese W(1)W?W?. 81ZW. COM
Their age is too small to look like four or five years old, and their faces are childish.
Innocent, they can't follow their parents to explore the ruins of unknown danger, so they are left outside by their parents, and it is strictly forbidden to get close to the ruins.
As for their brothers and sisters, they are armed with simple weapons, followed by their parents, trying to find items in the ruins that are likely to be exchanged for food.
Stepping forward to the children, Tang Zhen squatted down and stared at one of the children.
"Little guy, can you show me the things on your neck?"
This child seems to be a mixture of human and other aliens, his eyes are round and round, and it looks quite cute.
After hearing the words of Tang Zhen, the little guy raised his neck very boldly and handed the things hanging on his chest to Tang Zhen.
This is an extremely rough pendant that seems to be naturally formed, shaped like a rising flame, with a strange surface and gorgeous colors.
If you look closely, it will now have traces of burning on the surface, such as the eclipse, which resembles the appearance of the meteorite.
At the moment when the pendant started, Tang Zhen knew that this thing was exactly what he was looking for, and Ling Xuzi called it the iron of the void!
This piece in the hands of the little guy is enough to make a storage ring, which is extremely precious for Tang Zhen.
"I like this thing very much. I exchanged things with you. I don't know if you want to?"
As Tang Zhen’s identity, there is still no way to rob a child, so he will speak.
The little guy in the tiger's head has a distressed expression, his brows are wrinkled together, and he seems to be losing money if he considers the exchange.
When Tang Zhen saw it, he smiled and took out the same item and handed it to the little boy.
This is a jade card with the size of an egg. It is sleek and engraved with a rune. The center is also inlaid with a skull and the back is the coat of arms of the Holy Dragon City.
As long as the experienced wanderer sees the aura of the spread of the brain, he knows that this is a genuine lord-level brain, equivalent to 100,000 brains!
However, this is only the value of the brain itself. Now, when combined with Lingyu, the value is even more difficult to estimate.
This thing is worth a lot of money. Although the little guy is young, he knows that this is a good thing because it looks better!
Since I think this thing is better than my own, the little guy naturally knows how to choose, and does not hesitate to agree to the exchange.
Tang Zhen smiled and sat down to the side of the pendant and began to study the characteristics of this void iron.
The reason why he will give such a little thing to this little guy is because of the blood of the other people's race. Secondly, he also sees that this little guy is of good qualifications. If he cooperates with the gifted jade, he should have some achievements in the future.
This incident is only Tang Zhen's casual behavior, and there are no other special reasons.
Tang Zhen, who believes in his sin, knows naturally, so he is here to tell the younger parents how to solve the problem.
Of course, the main reason is to ask the parents of the little guy, where is the void iron?
It didn't take long for the little guy's parents to see a stranger sitting next to him, and rushed over, and looked at Tang Zhen with vigilance.
The little guy got a good thing, naturally he wants to show off to his parents. He handed the jade card to his father, and his face was full of praise.
The father of the little boy changed his face. After careful scrutiny, he took the jade card and walked to Tang Zhen.
Although he couldn't see Tang Zhen's cultivation, but he was very clear in his heart, he was able to take out this precious jade card and give it away. Tang Zhen's identity is definitely not simple.
Things are good things, but falling into the hands of their own children is a curse, because there are things that people like them can have.
At this point, the child's father is very clear.
"This gentleman, your kindness is our heart, but this thing is still asking you to take back..."
The child’s father said that he was stopped by Tang Zhen.
He glanced at the human man with the color of the wind and frost, and said with a chuckle: "This child is a good qualification. You are looking for a chance to bury this jade in his body and the wound will heal automatically.
With the help of this jade card, as long as he works hard to cultivate, when he reaches adulthood, he will certainly have a good repair!
I have already told you about the solution. Believe it or not, I will not take back the jade card. I will stay with you and sell it with you!

Tang Zhen had a hard time explaining so much. After a pause, he raised the pendant in his hand: "Where did this come from?"
The child’s father has already recovered the jade card and replied with respect and respect:
This is what I got from the grassland. When I looked pretty, I used it as a toy for my child.

Tang Zhen heard his heart pounding and continued to ask: "Which grassland can you see here?"
The child’s father nodded and pointed his finger at the area in front:
It’s the grassland not far away, and it’s close to the central area!

Tang Zhen nodded. The diary only recorded that there were meteorites falling, but there was no specific place. This is also a place where Tang Zhen felt embarrassed.
I did not expect that the location of the fall was in front of me, but it also caused a lot of trouble for Tang Zhen.
It is only this kind of void iron that can shield the mental power detection. The mental power scan that Tang Zhen used before is not suitable for finding such items.
He once downloaded an application called [Advanced Treasure Detector], which should be able to detect this kind of void iron, but Tang Zhen tried it, but it had no effect at all.
In the end, there is no empty iron in that place, or is the detection method and mental power of this application similar, so it cannot be detected at all?
After Tang Zhen came to the grass, he looked and looked for it.
This method of searching for things is a waste of time, and at the same time very inefficient, and Tang Zhen can only see the empty iron that may exist on the ground, and the bottom of the soil cannot be seen at all.
The grassland at the foot is very large. If you look for it one inch at a time, you can't search for it in a short time.
Although the Nether Iron is very important, Tang Zhen can't waste time here, so he has to find a way to solve this problem.
After thinking about it, Tang Zhen sent it back to the original world and appeared in the base of the American League.
After seeing Tang Zhen appear and knowing his intentions, about ten minutes later, a soldier sent a metal detector.
Using the instrument to sweep through the void iron, and surely the sound of the prompt, which makes Tang Zhen face the joy of color.
Buried in the soil, still does not affect the detection effect, obviously this military equipment is very reliable.
With this kind of equipment, Tang Zhen does not need to look for the empty iron shovel. As long as he hires a group of wanderers and teaches them to operate and use, they can wait for the results.
"Help me prepare 50 such devices, the sooner the better!"
Tang Zhen waited for about two hours, a group of new equipment that was debugged was placed in front of him, and he was brought to the world of the city.
Coming to the ruins, the little boy’s father was called, and Tang Zhenyang raised the metal detector in his hand.
"Help me find a hundred people to work, the price I double!"
