At that moment, Yang Tian and David left the Washington Public Security Department, got into a Ford sedan, and drove towards the Columbia Trading Center outside the suburbs.

Still halfway through, Yang Tian made a phone call.

The call was made to the Chen family mansion in Washington.

As soon as the phone rang, Wu Yue's crisp voice rang: "Hello, who are you looking for?"

"It's me, Yang Tian......"

Yang Tiandao.

"Yang Tian, where are you now, what have you discovered, why don't you just want us to follow?"

Wu Yue split his head and said.

"We're going to the Columbia Trading Center just outside Washington. Yang Tiandao: "We have analyzed the ingredients in the red test-tube potion, which may have been obtained from the Columbia Trading Center, so let's take a look, and you should pay attention to safety." ”

After speaking, Yang Tian wanted to hang up the phone.

But Wu Yue said anxiously: "Yang Tian, the Chen family's mansion is very safe here, just let me and Sister Yingying go to see what is going on! ”

"No!"

Yang Tian shook his head.

"If it doesn't work, we have to go!"

Wu Yue's attitude was also very tough, and he hung up the phone with a snap.

Yang Tian frowned, but he knew Wu Yue's character, she was very stubborn, if she decided on one thing, she would definitely not give up until she reached it.

When the car came to the Columbia Exchange Center in the suburbs, it was already two hours later, although Washington was very large, but the normal speed of the car, it could be reached in an hour, but the road was full of traffic jams, and it was already a fluke to arrive in two hours.

"Yang, as long as we find the source of radium-like minerals, we can make meritorious contributions, and I will be reinstated at that time, and you will accept the medal that the Washington Police Department personally awarded you!"

David said excitedly.

"Let's go in and take a look. ”

Yang Tian said lightly.

At that moment, he walked towards the lobby of the Columbia Trading Center.

It's very lively.

There are stalls everywhere, where mineralists from all over Washington state gather, some setting up stalls to trade their minerals and ores, others coming to buy ores and minerals, and the whole hall is the size of three football fields.

Here, there are rough stones, but also some stone carvings, ores, minerals and the like.

"Yang, there are so many ores and stalls here, how can we find radium-like substances?"

David said with a bit of a headache.

Yang Tian didn't say anything, but walked forward.

On these stalls, there are pure rough stones for sale, and there are also some gambling stones for cutting.

Along the way, every time Yang Tian passed a stall, he would run his divine sense, open his perspective eye and probe inside the rough stones and ores on the stall, in which, Yang Tian sometimes found some gems and sometimes some minerals, but he didn't find any radium-like substances.

After walking around like this for a while, Yang Tian stopped and said to David, "Let's find a place to rest." ”

"Stop looking for radium-like substances?"

David asked, confused.

"I'll talk about it later......"

As soon as Yang Tian was halfway through speaking, a voice sounded next to him: "You want to find a radium-like substance?"

Yang Tian frowned, looked back, not far from the side, there was a stall, and there was a man standing on the stall, this man was holding a cutting type saw knife in his hand, and at a glance he knew that it was the cutter of this stall.

It's just that this man is not Caucasian, but a sub-businessman.

"You also know radium-like substances?"

David looked at the man warily.

"Oh. The man's face was calm: "It's not just you, there are some people who have come here recently to look for the so-called radium-like substance, and I've always been puzzled. ”

"Lately, some people have been coming here looking for radium-like substances?"

David became more vigilant.

"That's right!" the man nodded, but said, "However, I advise you to give up, there is no radium-like substance here, but if you want to find other gems, you can come here to gamble on stones." ”

Yang Tian glanced at the stall in front of the man, there were several rough stones on it, some of which were half-ground.

Seeing this, Yang Tian's divine sense probed into these primordial stones.

Soon, a flash of sharpness flashed in his eyes.

Because inside a rough stone, Yang Tian clearly felt the light emitted by a trace of radium-like substance.

Although this glimmer of light was very faint, Yang Tian was still very clear that there was a radium-like substance in this rough stone.

"Yang, let's go look somewhere else. ”

David heard from the man that there was no radium-like substance, so he didn't want to linger too much.

"Don't worry, let's play the gambling stones of Milan. Yang Tian said a word, then patted a rough stone in front of him, and said, "I want to open this piece of rough stone and cut it for me from beginning to end." ”

"Oh?"

The man looked at Yang Tian seriously.

It's just that for some reason, the light in the man's eyes became very confused, and he suddenly said seriously: "This gentleman, are you from Huaxia Kingdom? How many days have you been here? Are you here for tourism?"

Yang Tian frowned.

His instincts told him that there was something wrong with the man.

But for a while, Yang Tian didn't know much, he said lightly: "We are here for tourism." ”

"Oh. The man nodded, but when he lowered his head, a trace of surprise flashed in his eyes, but he didn't show too much surprise, on the contrary, he picked up the cutting knife and said, "Sir, if you want to cut it all, the price will be higher, 200 dollars!"

"Well, I'll pay for it later, just cut it. ”

Yang Tian said lightly.

"It's on!"

The man began to cut, and with a crackling cutting sound, soon a rough stone the size of a football was cut in half, only at this moment, shockingly, a blood-red light emanated from the center of the stone.

"What's going on?"

The man's face was shocked, he looked towards the middle of the stone, and his face quickly changed: "This ...... This ......"

"It's radium!"

David had seen Diana extract the radium-like substance in the laboratory, so he recognized it at a glance.

"I don't know, is this a radium-like substance?"

Yang Tian asked lightly.

Then, he took out the piece of mineral the size of a fingernail from the middle of the rough stone.

The face of the man on the side changed, and he hurriedly said: "This gentleman, I don't know what kind of mineral this is, but you gambled on it, so we will spend a lot of money to buy it from you, and such a mineral is worth at least 5 million US dollars!"

"$5 million?"

Hearing this, David gasped.
