Su Yu's guess is reasonable, but I don't know why, no matter how many times she loses the probe, the result of the probe is the same-

【An ordinary dead tree】

Status: Deceased

Description: This is a dead tree with a large body and a long history......

……

There was very little information about the dead tree, so little that Su Yu couldn't see any problems, so much so that for a moment she really thought it was just an ordinary dead tree.

Soon, though, she remembered the prism in her backpack...... This is something that has never been used before, and it may be an important item to lead to the final boss.

Taking out the black prism, Su Yu glanced at the information first, the information of the black prism was the same as before, there was no change, she fiddled with it a little, and the dead tree did not change at all.

Just as Su Yu was thinking about what was going on with this copy, a beam of sunlight suddenly shone directly on Su Yu's face, and the dazzling sunlight made her subconsciously close her eyes and tilt her head, and then took two steps back.

When I opened my eyes, the sunlight was still there, and the golden light looked out of place in the lifeless, gray wasteland.

Su Yu subconsciously grasped the things in her hand, and when the palm of the prism was a little painful, she suddenly reacted to something......

Prism, sunlight, dead trees......

Although Su Yu felt a little strange, this operation was quite logical and reasonable...... So the way to trigger this boss is to use a black prism to refract sunlight onto a dead tree, and then trigger a fire to attract the boss?

Su Yu told her guess, and then after everyone rested, she put the black prism in the sunlight, and then adjusted the angle......

It is also strange to say, obviously the distance of sunlight is far away from the dead trees, after all, one is on the shore of the lake, and the other is in the center of the lake, although the lake is not large, but the diameter is also about 100 meters, no matter how powerful the normal prism is, it is impossible to refract the sunlight to a position 100 meters away.

But the truth is that it was done.

In this inherently unscientific world, there is no need to use science to explain many things.

The moment the sun fell on the dead tree, nothing happened to the dead tree, but this is normal, even if it can catch fire, it is certainly not a matter of a while, it will take time.

But before the thought had passed, a puff of black smoke rose from the point where the sunlight came into contact with the dead tree, and it looked as if it was about to burn.

"I think I see smoke coming out?"

"I saw it too, is this sunlight so powerful?"

Originally, everyone heard Su Yu say that they would use a black prism to refract sunlight on the dead tree, and then let the dead tree burn, this alone sounded a bit outrageous, but they didn't care, anyway, they also saw that it was not normal here.

But they never imagined that this burning speed would be so fast!

The smoke started in three seconds, the sparks appeared in seven seconds, and by fifteen seconds, they could already see a small flame burning.

In less than half a minute, the fire had grown irreversibly.

In the last ten seconds, the small flames below basically flew into the air at a rapid speed, and then climbed directly to the whole body of the dead tree, and finally entangled with the trunk of the tree, wrapping the brown exterior in flames, and then gradually turning black......

At this time, a gust of wind blew, bringing a slight chill, and at the same time, it also directly blew away the dead trees that had been burned to ashes.

There used to be a big tree here that required hundreds of people to hold hands, but in just one minute, it disappeared completely, leaving no trace, as if it had never existed......

As the last bits of ash disappeared into the air, a cluster of flames burst out of nowhere and ignited the lake, and the frozen ice quickly ignited a raging fire, which continued to spread until it covered the entire surface of the lake.

But what is puzzling is that there is a high-temperature flame above, but the ice surface below has no intention of melting, which makes Su Yu not know for a while whether to suspect whether this ice is fake ice or this fire is fake fire.

Seeing that although the flame was not getting stronger, it did not stop at all, Su Yu asked Meke to clear a small area, so a circular flameless area with a radius of about two meters appeared on the shore.

"How's the consumption? How long can it last? While Su Yu was preparing to explore the ice, he also asked Meke about the consumption of cleaning up the flames.

After all, although this ice that doesn't melt is weird, this flame that can't even melt the ice is not much better, obviously it's not a normal thing, Su Yu is worried that Meke needs to consume too much magic to disperse these flames, so it's not worth it.

High-level magician magic is not something that can be recovered by a few low-level magic potions.

"Don't worry, don't talk about this small piece of fire, even if I put out the fire on the entire ice." Meke snorted, and the tone of his voice was still so familiar.

But pretending to be coerced is pretending, and Meke is not a big talker, which means that at least he does feel that there is nothing wrong with cleaning up these flames with his own strength.

Could it be that this fire is normal fire, but this ice is not normal ice?

Anyway, Su Yu led the people to the ice, and then crouched down to inspect the ice - the tentacles were cold and piercing, and the appearance was smooth, at least in terms of appearance and touch, this was indeed ice.

"Lord Lord, this seems to be an ordinary ice surface...... The people who said this were a little weak-hearted, after all, everyone obviously thought that this could not be ice, but they couldn't see any other problems.

The atmosphere was a little stiff for a while, and Su Yu couldn't help but think that it would be nice if Sha Ling was here...... Sha Ling has actually woken up, and her strength has stabilized, listening to Anita, the current Sha Ling should be at the level of an intermediate ice magician.

If she was here, the identity of the ice magician would definitely be able to see other problems, after all, the professional counterpart.

But this is just a thought, Su Yu was not ready to let Sha Ling come back during the beast tide at all, because Sha Ling, like Lin Chen and Lin Duan, was the target of the people behind this beast tide.

Although she has the strength of an intermediate magician, she is a child after all, and she is not afraid of ten thousand.

So after thinking about it, it is still the safest elf clan, and it just so happens that the queen can help to see if there are any other problems with this child, so Su Yu has never asked the elf clan to send people back.

Coming back in a circle, Su Yu took out the pickaxe used for mining from his backpack......
