"I remember...... Zhao Yu said to Li Beni while cautiously driving after him, "In Yuan Juncheng's information, there is a description of the Yishan Fortress! During the puppet Manchu government, the Yishan Fortress has always been regarded as the gateway to the entire Fengping region. Yuan Juncheng once suspected that there should be other supporting fortifications built on the front of the Yishan Fortress! Therefore, he conducted research and investigation on this area back then, but found nothing.

"Front...... But ......," Cui Lizhu said, looking at the map on her phone, "we are now on the back of the Uisan Fortress......!

"That's right!" Zhao Yu said, "The back of the Yishan Fortress is full of cliffs, and it is not in the strategic area, so neither Yuan Juncheng's team nor the previous experts have carried out a large-scale exploration of this place......!"

"But......" Cui Lizhu snapped her fingers, "This is exactly the trick of the Japanese devils, deliberately building a fortress in a place with no strategic value, which can not only achieve unexpected results in the war, but also an excellent location for hidden treasures!" Wow............ God forbid, God forbid, please let my boss solve this case, so that my big house will be settled......"

Just as Cui Lizhu was chattering, the blue pickup truck in front of her turned deeper into the mountains, the road became more and more rugged, and the pickup truck was loaded with heavy machines, so it drove more and more slowly.

Zhao Yu didn't dare to get too close, so he could only slow down and follow from a distance.

The heavy rain still hasn't abated, and it's still falling in a hurry. As we continue to go deeper into the mountains, cliffs gradually appear on both sides of the road, which is not dangerous.

After following for more than 20 minutes, there was almost no road in the mountains, and it became more and more difficult to walk.

Finally, after following the pickup truck through a wooded field, the pickup truck finally stopped under a steep cliff.

Fortunately, there was a forest to cover it, so Zhao Yu and the agents behind him hurriedly stopped the car, and then used binoculars to observe the movement of the pickup truck.

Thundered......

At this moment, there was also a sullen thunder in the mountains, which made people uneasy.

"Get out of the car, get off the car......" Although Cui Lizhu does not have binoculars, she is born with good eyesight and can still see two people getting off the pickup truck.

The two men, presumably dressed in raincoats, got out of the car at a rapid pace, and then worked together to move a huge machine off the car, and down the hill, where they began to tie the ropes......

Although they were expected to have a telescope, because the rain was too heavy, Zhao Yu still couldn't see their specific movements and the appearance of the two.

However, Zhao Yu could vaguely tell from the action of their ropes that they should want to carry the heavy machine up the cliff.

Sure enough, a few minutes later, one of them climbed up the rope on the cliff face. Only then did Zhao Yu notice that at the height of that cliff, there was a cave that was not very big.

After a while, the heavy machine began to slowly rise, heading towards the cave.

"Oops...... Go up, go up!" Cui Lizhu pushed Zhao Yu, "Boss, aren't we going to arrest people now?"

"Wait!" Zhao Yu frowned and pondered, "Since they have entered the cave, they naturally can't escape! Don't forget the matter of the expert's murder, the other party is likely to be more than these two people, it's better to be careful!"

"That's good......" Cui Lizhu said again, "You hurry up and contact Li Jing and apply for support, right?"

"Hmm......" Zhao Yu picked up his phone, but his eyes were still looking into the distance. At this moment, the two men had transported the largest of the machines into the cave. Subsequently, they began to transport other machines and equipment on the truck......

Boom......

Who knows, Zhao Yu was about to pick up his mobile phone to dial Li Jing, when his car door was suddenly opened from the outside, and with a gust of cold wind blowing in, he saw a woman in a black windbreaker quickly get into their car.

I click......

Zhao Yu looked back and was taken aback by Cui Lizhu, but saw that the person who suddenly got into the car was none other than that Li Jing - Captain Li!

"Are you ......" Zhao Yu's eyes widened and exclaimed, "Is it so fast?"

"It's nothing!" Li Jing dusted off the drops of water on her long hair and said lightly, "When I contacted you, I was already almost in Linshe County! You drove so slowly, you were naturally able to catch up! Team Leader Zhao, what's the situation now?"

"They are transporting the purchased machine up to the cave!" Zhao Yu handed the telescope to Li Jing, although there were all kinds of grievances and estrangements with this woman, but at this moment, Zhao Yu still felt a little more down-to-earth about her appearance.

"Can be sure...... Are those two Tian brothers?" asked Li Jing as she observed.

"No!" Zhao Yu replied truthfully, "Those two grandsons have been wearing hats......! You see they're very skilled at transporting machines, which is kind of in line with the profession of those two people!"

"Yes, therefore, there is a very high possibility that they are the Tian brothers!" Li Jing said, "Even if they are not, after all, they use the Tian brothers' bank cards, and they must have a lot to do with them!"

"That'...... We ...... now," Zhao Yu glanced at Li Jing.

"Don't worry!" Li Jing said, "Don't forget about the killing of the expert, the other party is likely to be more than these two people!"

"Well......" Cui Lizhu snorted her teeth, but she didn't expect that Li Jing's words were exactly the same as Zhao Yu's, almost without a word.

"In that case...... Zhao Yu also said cautiously, "Then let's call more people over!"

"Don't worry, don't worry!" Li Jing pointed behind her, "The people I bring now are enough to deal with!"

"No......" Zhao Yu hurriedly reminded, "Captain Li, it's better to be careful! Think about it, since they dare to blatantly use bank cards to settle payments, maybe there is something tricky, we have to guard against it?"

"I know!" Li Jing said as she observed the movement in the distance, "but...... We can't be 100% sure that the Tian brothers must have something to do with the murder of the expert!

"Using a bank card, it may also be because they have no money! Entering the cave, maybe not for the treasure!" said, Li Jing put down the binoculars and said, "It's raining so heavily, if I take the risk to apply for support, once there is an oolong, neither of us will look good!"

"Honestly!" Li Jing said with a frosty face, "I don't believe at all, the treasure would be hidden in such a place! According to the information of the secret service, the entire mountainous area of Linshe County has been scanned by remote sensing and field exploration, even if the treasure really exists, it is impossible to bury it here!"

Hearing this, Zhao Yu subconsciously looked at the map on his mobile phone and found that the cliffs in the distance were only six or seven kilometers away from the Yishan Fortress, and they both belonged to the same mountain range.

In fact, Zhao Yu and Li Jing feel the same, and he also thinks that treasures are not so easy to find. However, when he thought of his "Kungen" hexagram, he had to have a strange feeling.

"Okay!" Li Jing said to Zhao Yu and the others, "Those two people have all entered the cave, let's go over and have a look!Team Leader Zhao, if you still have concerns, then you can stay here and stay in touch!"

After speaking, without waiting for Zhao Yu to react, she opened the car door and got out of the car first.

"Damn, provoke, provoke!" Cui Lizhu was anxious, and hurriedly slapped Zhao Yu on the back, "Boss, hurry up! You are a mad detective, at this time...... You're not going to admit it!?"
