How strong Liu Haoyu is, Du Su doesn't know in his heart.

But he knew that if there was anyone who had the best chance of solving the strange incident in the mine, it would be Liu Haoyu!

It's a trust in his strength!

Du Su once heard his father say that Liu Haoyu's strength can be called the number one master on the earth.

Of course, he didn't know whether what his father said was true or false, maybe it was a certain exaggeration!

"How far is it?" Looking at the passing scene outside the window, Liu Haoyu asked lightly.

Outside the car window, there are fewer and fewer high-rise buildings on both sides of the road, and the route they travel is becoming more and more remote, gradually moving away from the city and into the suburbs.

However, Du Su had no intention of stopping, and there was no shadow of the mine in front of the vehicle.

"Senior, the mine is a bit far away, and it may take nearly half an hour to go!"

Liu Haoyu frowned slightly, closed his eyes and said, "Then I'll rest for a while!"

Du Su hurriedly replied: "Okay, I'll be a little steady!"

After the journey, Liu Haoyu felt that he could clearly perceive that the bumpiness of the car had been greatly reduced.

In fact, he was just closing his eyes and recuperating, but Du Su didn't know it, and he also understood the wrong meaning.

Arrived a little later than expected, about forty minutes later, and finally arrived at the mine.

Perhaps, this is also because Du Su has reduced some of the speed of the car to keep it stable.

"Senior, it's here!"

As soon as Du Su's words fell, Liu Haoyu opened his eyes.

He glanced out the window first, and his expression did not fluctuate.

There are few trees on the mine, and the altitude is not very high, but it covers a large area that stretches for more than a dozen kilometers.

Du Su got out of the car, walked to the back diligently, and took the initiative to open the car door for Liu Haoyu.

After getting out of the car, Liu Haoyu looked around a few times, and there was almost no one nearby.

Liu Haoyu observed for a moment, raised his eyebrows and asked, "This is an iron mine?"

Du Su nodded and said bitterly: "Yes, senior! This is an iron mine, which is estimated to be worth hundreds of billions, so our Du family really can't give up easily!"

Liu Haoyu nodded slightly, didn't say much, and walked directly towards the nearest mine cave in front of him.

Du Su hurriedly followed.

At this moment, a few people suddenly came over and greeted Du Su politely: "Young Master Du, are you here?"

"Hmm!" Du Su nodded, and the representative said hello.

"Who is this ......?" several people looked at Liu Haoyu who was walking towards the mine with puzzled eyes.

Du Su frowned, waved his hand, and said: "This is the master I invited to help, this place is dangerous, so everyone should go back!"

"What?"

The faces of those people changed, and they were all extremely ugly.

One of them walked out, looked at Du Su with a gloomy expression and said, "What Young Master Du did is a little unauthentic, isn't it? Our two families have cooperated for so many years, and this time when we heard that the Du family had suffered this incident, we took the initiative to come to help, and your Du family did not refuse before!"

"And now, you're telling us to leave! What does this mean? Do you look down on the strength of a few of us, or do you look down on our Xuanyang faction?"

Du Su said indifferently: "A few people have misunderstood! I don't mean to look down on you and your faction, it's just that there is indeed an unknown danger hidden in this mine, and even a few worshippers of my Du family have been ordered to fall here......

Before he could finish speaking, Du Su was interrupted.

"What's the matter? Young Master Du thinks that a few of us are not as good as those worshippers in your family? Or do you think that stinky boy with no hair is better than us guys?"

Hearing this, Du Su had a headache and felt a little troublesome.

He shook his head helplessly, and then said in a cold tone: "Since a few people insist on staying, then let it be you!"

With that, he left a few people behind and turned to leave.

Liu Haoyu kept his feet on his feet, and soon arrived at the location of the cave.

After a while, Du Su, who was delayed for a while, caught up.

Glancing at Liu Haoyu, who was staring at the entrance of the cave in a daze, Du Su asked cautiously: "Senior, do you see anything?"

Liu Haoyu shook his head for a while and said, "I haven't found anything yet, but since everyone has an accident in this mine, you need to go deep into the mine to find something!"

At this time, those guys from the Xuanyang Sect all came over.

Listening to Liu Haoyu's words, one of the white-bearded old men twisted his beard and said: "The young man is a little bold, we have carefully inspected the outside of this mine, and there is indeed nothing to find, and the specific situation may really need to go to this mine to find the clues." ”

Liu Haoyu ignored him and stepped in directly.

Du Su hurriedly followed.

The ignorance of the two made several people from the Xuanyang faction look gloomy.

One of them said indignantly: "Elder, that kid from the Du family is inevitably too much! We came over to help with good intentions, and he actually dared to give us a look, it's really hateful!"

The white-bearded elder shook his hand and said, "Forget it! To put it bluntly, this time we came uninvited, and the strong intervention made the Du family a little unhappy!"

"Elder, there is news that the demon in this mine is the thing, is this news reliable?"

Elder Whitebeard shook his head and said, "I don't know! Let's wait until we find it! If it's really that thing, it's not necessarily easy to deal with, and the combination of several of us may be a little dangerous!"

"Elder, what are you waiting for! The two of them have already gone down, let's hurry up! If they find them first, it is estimated that there will be nothing to do with us!"

"That's not necessarily, just with the two of them, what can they do if they are found, aren't they sent to death!"

"That's right!"

During the conversation, several members of the Xuanyang Sect also went deep into the mine.

With the help of the light, Liu Haoyu probed unhurriedly.

For some reason, it's a little stuffy in this cave.

After a while, Du Su really couldn't help but say, "Senior, why don't we take a minecart!

"Don't worry! Walking like this will help you find some clues that are not obvious!" Liu Haoyu said lightly, looking back at Du Su, who was sweating slightly, and he said: "If you can't hold on, then go out! ”

"Well, I'd better follow! Father asked me to learn more from you!" Du Su said, expressing a hint of information.

Liu Haoyu didn't hear it and didn't answer.

Seeing this, Du Su sighed helplessly.

He wanted to worship this senior as a teacher for a long time, but unfortunately...... People don't accept it!

In this regard, Du Su had no choice, and even his father came forward to request, but he was also politely refused.

PS1: Thank you P.Z.Z for tipping 400 points again!

PS2: Something happened today and I can't do two changes, I'm really sorry for everyone T_T......!
