Bai Yun and the others nodded slightly, the four of them didn't have this detector, so naturally they couldn't help much.

"By the way, since you can't use road signs, why not let Xue'er find your way?" Bai Yun said lightly.

"It's true that Xue'er can find her way, but you also have to find the road signs, so that Xue'er's ability to know the way can be maximized. Lu Da said slowly.

Bai Yun frowned, he was still a little puzzled, it stands to reason that since Xue'er is a snow-seeking BMW, she naturally knows the way, so why bother looking for any road signs.

But after thinking about it, if this is the case, it is better not to lead the team and just rent a snow hunting BMW.

"There must be other reasons. Bai Yun muttered to himself, and he didn't bother to think about it, as long as Lu Da could lead everyone into the depths of the Fog Snow Ridge.

The four of them began to rest, and although the snowstorm was heavy, it was not a matter of standing and did not know when the rock would be detected.

After more than ten minutes, Zhang Chongshan was still bored probing, and suddenly, his detector sounded the alarm, but due to the heavy snowstorm, the sound could not travel far, and only he could hear it.

"There's hard stuff down there. Zhang Chongshan looked overjoyed, and hurriedly made a mark here, and began to take out the ordnance shovel and began to shovel snow.

Although the snow here is very thick, it will not take long to dig down with the strength of one person, after all, this snow is much easier than shoveling dirt.

Zhang Chongshan was tired enough, and he dug for ten minutes, barely to the end.

"What a rock. Zhang Chongshan couldn't help laughing.

If he Zhang Chongshan was the first to dig up the rock with road signs, it would be more face-saving.

He hurriedly began to dig again, and just now he only dug about a man wide, and found no so-called road signs.

Another twenty minutes passed, and Zhang Chongshan looked surprised and a little helpless, because he found that the rock he had excavated seemed to be a little big, and it felt like it had not reached the end at all.

And the part that has been exposed has no mark, and what makes him even more speechless is that due to the heavy snowstorm, the part that has just been dug is covered with another layer of snow.

Zhang Chongshan really wanted to cry without tears.

"Forget it, let's go back and dig it up with everyone. Zhang Chongshan sighed slightly.

After making a slight mark here, he walked towards the place where Bai Yun and the others were.

Just when Zhang Chongshan found the rock, Professor Zhou's side also sounded the alarm at the same time, and he calmed down, and like Zhang Chongshan, he began to shovel snow.

However, Professor Zhou is old, and the speed of shoveling snow is naturally not as fast as Zhang Chongshan's, and after shoveling some quickly, it is covered again.

Professor Zhou shook his brows and hurriedly went back to find Bai Yun and the others.

Bai Yun and the others naturally moved when they heard the wind, and after fixing Xue'er, the four of them followed Professor Zhou together and returned to the alarm point.

"This is where hard objects are detected. Professor Zhou said slowly.

"Lu Da, what do you think, is there an impression here?" Bai Yun said lightly.

"Since the marker is gone, the surrounding environment is generally similar, and the Phantom Aurora itself has a psychedelic effect, I honestly dare not say whether it is here or not. Lu Da frowned, but still said truthfully.

"In that case, let's start digging here, with the strength of the five of us, it won't take much time. Bai Yun said lightly.

"But we don't have any tools. Su Yan said slightly, she naturally wanted to contribute, but it was a little difficult to throw snow with both hands.

"It's okay, don't you have any pots and pans in your backpacks? It's not as quick and easy as a shovel, but it's okay. Bai Yun said lightly.

"That'...... Well, that's all there is to it. Su Yan said slightly, and then quickly took out some iron cutlery.

"Lu Da has the best strength, you can use the armor shovel, so that the speed will be faster. Professor Zhou said, and then threw the ordnance shovel to Lu University.

Lu Da picked up the ordnance shovel, and without saying a word, he began to shovel the snow hard.

"Let's get started, too. Seeing that Lu Da was working so hard, Bai Yun also said to everyone.

In an instant, the four of them picked up a spatula and even an iron basin and began to dig.

The five of them shot together, and the speed was really much faster, and they soon dug into the lower layer, leaking out the rock body, and the area was not small.

"How's it going, have you found the mark?" Bai Yun said slightly.

Lu panted and shook his head, indicating that he had not found it.

Su Yan and the others were also drenched in cold sweat, using utensils to dig up snow, but it was more tiring than the ordnance shovel.

"That mark is at the root of the tree, even if the tree is burned by fire, or broken, the roots will still remain, and it will not really disappear completely and inexplicably, as long as we continue to expand the area along this rock, we may be able to find the roots of the tree, so as to find the road signs. Lu Da said slowly.

"It seems that this is the only way to die now, so I'm going to call the others and dig together. Professor Zhou said slightly.

Less than ten minutes later, except for Zhang Chongshan, the other eight people all came here, and they didn't go too far, and they didn't find the rocks, so they came together.

"Why is there one person missing?" Lu Da said slightly.

"Maybe the distance of Chongshan is a bit far, and we haven't found him, so let's dig it quickly, otherwise the part that has been dug will be buried again. Professor Zhou said slightly.

After listening to Professor Zhou's words, everyone immediately started to move.

There is a lot of strength in numbers, especially nine sapper shovels, and this speed can be imagined.

And Su Yan and Song Ru were not idle, still holding the tableware and throwing the snow.

Su Yan was tired and panting, but in order to find the road sign as soon as possible, she also gritted her teeth and worked hard to clear the snow.

"Huh, what is this?" Su Yan was slightly startled, just now, she seemed to have touched a hard object, but the feeling was not the same as a rock.

Resisting the doubts in his heart, Su Yan added a lot of strength and quickly dug up.

"This ...... This is ......" Su Yan looked shocked, and then smiled slightly.

"Here, I've dug up the roots. Su Yan shouted loudly.

"What? Did you really dig up the roots?" Lu Da looked surprised, and hurriedly threw away the place he had dug.

The others also stopped what they were doing and gathered over.

"Sure enough, it's the root of the tree, although I don't know if it's the one, but as long as you dig deeper, you can see it. Lu Da said slowly.

Since the root of the tree was found, the rest of the people naturally did not need to dig at will, and more than a dozen people began to dig around the root.
