538 Void iron, with the help of technology

Under the bright sunlight, a few children in tattered clothes were playing on the grass.

They were really too young, and they looked like they were only four or five years old. Their faces were full of childishness.

They were still young and could not follow their parents to explore the ruins with unknown dangers, so they were left outside by their parents and were forbidden from approaching the ruins.

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

Tang Zhen slowly walked to the front of the children. He squatted down and stared at one of the children.

"Little guy, can you let me see the thing on your neck?"

This child seemed to be a mixed-blood of the human race and other races. His eyes were wide open, and he looked very cute.

After hearing Tang Zhen's words, the little fellow raised his neck in a forthright manner and passed the thing hanging on his chest to Tang Zhen.

It was an extremely crude pendant that seemed to have been formed naturally. It looked like a ball of rising flames, and its surface was covered with strange patterns and gorgeous colors.

If one looked closely, one would find that its surface had traces of melting and burning, similar to the appearance of a meteorite.

The moment Tang Zhen touched the pendant, he knew that it was the item he had been looking for. Lingxu Zi called it void iron!

The piece in the little fellow's hand was enough to make a storage ring. It was extremely precious to Tang Zhen.

"I really like this thing. I have something to exchange with you, I wonder if you're willing?"

With Tang Zhen's identity, he would not do something like robbing a child. Hence, he asked.

The well-built little guy showed a difficult expression and frowned, as if he was considering whether he would be at a disadvantage if he exchanged.

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

It was a Jade tablet about the size of an egg. It was warm, clear, and carved with runes. A bright pearl was embedded in the center, and the Holy Dragon city's coat of arms was on the back.

Experienced Wanderers only needed to look at the Halo spreading from the brain Pearl to know that it was a genuine Lord-grade brain Pearl, which was equivalent to 100000 brain pearls!

However, this was only the value of the brain itself. Now that it was combined with the spiritual Jade, its value was even more difficult to estimate.

It was obvious that this thing was valuable. Although the little guy was young, he knew that it was a good thing because it looked even better!

Since the little fellow thought that this item was better than his, he naturally knew what to choose and agreed to the exchange without any hesitation.

Tang Zhen smiled. After receiving the pendant, he sat to the side and began to study the characteristics of this void iron.

The reason why he had given the little fellow such a precious item was firstly because of his human bloodline, and secondly because he could see that the little fellow had good aptitude. If he were to combine it with the spirit Jade he had given him, he would definitely have great achievements in the future.

This matter was just something that Tang Zhen had casually done. There was no other special reason for it.

Tang Zhen naturally understood the principle of "treasuring a jade ring will lead to a crime." Therefore, he had waited here to tell the little fellow's parents the solution to this problem.

Of course, the most important reason was to ask the little guy's parents where they had gotten this piece of void iron.

As expected, it did not take long for the little fellow's parents to see a stranger sitting at the side. They hurriedly rushed over and sized up Tang Zhen vigilantly at the same time.

The little guy got something good, so he naturally had to show off to his parents. He handed the Jade card to his father, his face full of praise.

The little boy's father's expression changed drastically. After carefully sizing him up, he took the Jade tablet and walked in front of Tang Zhen.

Although he could not see through Tang Zhen's cultivation, he was very clear in his heart that Tang Zhen's identity was definitely not simple since he was able to casually take out such a precious Jade token and give it away.

It was a good thing, but it was a disaster rather than a blessing for it to fall into their children's hands, because some things were not something that people like them should have.

On this point, the child's father was very clear.

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

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

He glanced at the man who looked like he had been through a lot, then chuckled and said, " "This child's aptitude is not bad. Find an opportunity to bury this Jade card in his body and the wound will automatically heal.

With the help of this Jade token, as long as he worked hard in cultivation, he would have a good cultivation when he reached adulthood!

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

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

The child's father had already kept the Jade tablet and replied respectfully, " "I picked this up from the grassland. It looks pretty, so I gave it to my child as a toy."

Tang Zhen's heart jumped when he heard this. He continued to ask without changing his expression,"Which grassland? can I see it from here?"

The child's father nodded and pointed to an area in front of them. it's the grassland not far away. It was found near the central area!

Tang Zhen nodded. The diary only recorded that there was a meteorite falling, but it did not record the specific location. This was also what made Tang Zhen feel awkward.

He did not expect that the crash site would be right in front of him. This had saved Tang Zhen a lot of trouble.

It was just that this kind of void iron was able to shield one from mental energy detection. The mental energy scan that Tang Zhen used in the past was not suitable for searching for such an item.

He had once downloaded an application called [ high grade treasure detector ]. It should be able to detect this kind of void iron, but Tang Zhen had tried it and had no effect at all.

Was there no void iron in that area, or was the detection method used similar to mental power, so it couldn't be detected?

After Tang Zhen arrived at the grass patch, he pondered as he searched.

This method of searching was very time-consuming and inefficient. Moreover, Tang Zhen could only see the void iron that might be on the ground. He could not see anything under the soil.

The grassland under his feet was very large. If he relied on himself to search inch by inch, he would not be able to complete the search in a short time.

Although the void iron was very important, Tang Zhen couldn't waste his time here. Therefore, he had to find a way to solve this problem.

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

After seeing Tang Zhen's appearance and knowing his intention for coming, a soldier sent a metal detector over after around ten minutes.

He used the device to scan the void iron and a prompt sound was indeed emitted. This caused Tang Zhen to reveal a happy expression.

Burying it in the soil would not affect the detection effect. Obviously, this military equipment was very reliable.

With the existence of such equipment, Tang Zhen no longer needed to worry about finding void iron. He only needed to hire a group of Wanderers and teach them how to operate it. Then, he could wait for the results.

help me prepare 50 of this equipment, the faster the better!

Tang Zhen waited for about two hours before a batch of new equipment that had been tested was placed in front of him. He brought all of them to the world of loucheng.

When he arrived at the ruins, he called the little boy's father over and Tang Zhen waved the metal detector in his hand.

"Help me find 100 people to work for me, and I'll double the price!"
