I have a city in another world

Chapter 536 The iron of the void, technology helps!

Under the bright sunshine, several children in ragged clothes were playing on the grass.

They are too young, they don't look like they are four or five years old, and their faces are full of childishness.

They were immature and could not follow their parents to explore the ruins with unknown dangers, so they were left outside by their parents and were strictly forbidden to approach the ruins.

As for their older brothers and sisters, they held simple weapons and followed their parents, trying to find items that might be exchanged for food in the ruins.

Walking slowly in front of those children, Tang Zhen knelt down and stared at one of them.

"Little guy, can you show me what's on your neck?"

This child seems to be a hybrid of human race and other alien races, his eyes are round and round, and he looks quite cute with a tiger head and a tiger brain.

After hearing Tang Zhen's words, the little guy raised his neck boldly and handed Tang Zhen the thing hanging on his chest.

This is an extremely rough pendant, which seems to be formed naturally. It looks like a rising flame, and the surface is covered with strange lines and gorgeous colors.

If you look closely, you will find that there are traces of burning such as melting crust etch on its surface, which resembles the appearance of a meteorite.

The moment Tang Zhen got the pendant, he knew that it was exactly what he was looking for. Ling Xuzi called it the Iron of the Void!
The piece in the little guy's hand is enough to make a storage ring, which is extremely precious to Tang Zhen.

"I like this thing very much. I want to exchange that thing with you. Would you like it?"

As Tang Zhen, he still couldn't do the act of robbing a child, so he asked.

The tiger-headed little guy showed a embarrassed expression, frowning together, as if he was thinking about whether he would suffer a loss if he exchanged.

Tang Zhen laughed when he saw this, took out an item, and handed it to the little boy.

This is a jade tablet about the size of an egg. It is warm and transparent and engraved with runes. There is a bright brain bead inlaid in the center, and the coat of arms of Sacred Dragon City is on the back.

As long as experienced wanderers see the halo spreading from the brain bead, they will know that it is a genuine lord-level brain bead, which is equivalent to a hundred thousand brain beads!
However, this is only the value of the brain beads themselves, and now combined with Lingyu, the value is even more incalculable.

This thing is worth a lot of money at first glance. Although the little guy is young, he also knows that it is a good thing because it looks better!
Since he thought this thing was better than his own, the little guy naturally knew how to choose, and agreed to the exchange without hesitation.

Tang Zhen smiled, took the pendant and sat aside, and began to study the characteristics of this void iron.

The reason why he gave this little guy such a precious thing was firstly because of the other party's human blood, and secondly because he saw that this little guy had good aptitude. If he combined with the spirit jade he gave, he should have some achievements in the future.

This incident was just done by Tang Zhen at will, and there was no other special reason.

Tang Zhen naturally knew why Huai Bi was guilty, so he waited here to tell the little guy's parents how to solve the problem.

Of course, the main reason is to ask the little guy's parents where he got this piece of void iron.

Sure enough, not long after, the little guy's parents saw a stranger sitting beside them, so they hurried over and gave Tang Zhen a vigilant look.

The little guy got a good thing, so he naturally wanted to show it off to his parents. He handed the jade token to his father, with an expression of coming to praise me all over his face.

The little boy's father's complexion changed drastically, and after a careful look, he walked up to Tang Zhen with the jade plaque.

Although he couldn't see Tang Zhen's cultivation, he knew very well in his heart that Tang Zhen's identity was definitely not simple to be able to hand out such a precious jade token as a gift.

Things are good things, but if they fall into the hands of their own children, it is a disaster rather than a blessing, because some things are not something that people like them can have.

On this point, the child's father sees it very clearly.

"Sir, we appreciate your kindness, but please take this thing back..."

When the child's father said this, Tang Zhen waved his hand to stop him.

He glanced at the weather-stained human man, and said with a light smile, "This kid has good aptitude, if you find a chance to bury this jade tablet in his body, the wound will heal automatically.

With the assistance of this jade card, as long as he works hard, he will definitely have a good cultivation level when he reaches adulthood!

I've already told you the solution. Believe it or not, I won't take back the jade token. It's up to you to keep or sell it! "

It was rare for Tang Zhen to explain so much. After a pause, he raised the pendant in his hand: "Where did this thing come from?"

The child's father had already taken back the jade tablet, and replied respectfully: "This is something I picked up from the grassland. It looks very beautiful, so I used it as a toy for the child."

Tang Zhen's heart jumped when he heard the words, and he continued to ask calmly: "Which grassland, can I see it here?"

The child's father nodded and pointed to an area in front of him: "It's the grassland not far away. The place where I picked it up is close to the central area!"

Tang Zhen nodded. The diary only recorded that a meteorite fell, but did not record the specific location, which also made Tang Zhen feel embarrassed.

Unexpectedly, the crash site was right in front of him, which saved Tang Zhen a lot of trouble.

It's just that this kind of void iron can shield the detection of mental power, and the mental power scan that Tang Zhen used to use before is not suitable for finding this kind of item.

He once downloaded an app called [Advanced Treasure Detector], which should be able to detect this kind of void iron, but Tang Zhen tried it, but it didn't work at all.

Is there no void iron in that area, or is the detection method used in this application similar to spiritual power, so it cannot be detected at all?

After Tang Zhen came to the grass, he searched while thinking.

This method of finding objects is a waste of time, and at the same time it is very inefficient, and Tang Zhen can only see the void iron that may exist on the ground, and can't see the ones under the soil at all.

The grassland under our feet is huge, and if we only search inch by inch by ourselves, we will not be able to complete the search in a short period of time.

Although Void Iron was very important, Tang Zhen couldn't waste his time here, so he had to find a way to solve this problem.

After thinking about it for a while, Tang Zhen teleported back to the original world and appeared in the American League base.

After seeing Tang Zhen appearing and knowing his purpose, about 10 minutes later, a soldier sent a metal detector.

Sweeping the Void Iron with an instrument, there was a sound of prompting, which made Tang Zhen look happy.

Burying it in the soil still does not affect the detection effect. Obviously, this kind of military equipment is very reliable.

With this kind of equipment, Tang Zhen no longer needs to worry about finding the Void Iron. He only needs to hire a group of homeless people, teach them how to use it, and wait for the results.

"Help me prepare fifty such devices, the faster the better!"

Tang Zhen waited for about two hours, and a batch of brand-new equipment after debugging was put in front of him, and he brought them all to the world of Loucheng.

When he came to the ruins and called the little boy's father, Tang Zhen raised the metal detector in his hand.

"Help me find a hundred people to work, and I will double the price!"
