Tang Chen was completely sure that before fighting those monsters, there were absolutely no desolate crystals on the ground in this area, but now hundreds of desolate crystals suddenly appeared, which made him a little puzzled.

"Where did these desolate crystals come from?"

He thought about it secretly, and his soul sense carefully examined each desolate crystal, and found that these desolate crystals were all about the same size, and even the shape was the same, in the shape of multi-faceted droplets, most of which had nine faces, and very few had eight faces.

Judging from the appearance, these are not the same as the barren crystals he knows, according to the records, although the barren crystals are also multi-faceted droplet-shaped, but there are only three sides, three sides and nine sides, this difference is indeed a bit big.

The reason why Tang Chen was able to determine at a glance that these were desolate crystals was because they were not only similar in appearance to the desolate crystals recorded in the data, but also exuded faint soul power fluctuations as recorded.

As for why these have nine sides, but the data records only three sides of the barren crystal, he analyzed, it may have something to do with the grade of the barren crystal, maybe the higher the grade, the more surfaces it has......

Of course, this is just his personal speculation, and the specific reason is only possible to know after finding the desolate crystals on three sides and comparing the two.

"Could these desolate crystals be similar to the star cores of star beasts, the crystal nuclei of these monsters?"

Tang Chen's mind suddenly had a flash of inspiration, and he felt that this might be the closest conclusion to the truth, after all, these desolate crystals only appeared after those monsters were destroyed.

He didn't think much about it, put away all the desolate crystals, and then rushed back to the place where the disciples of the Mountain and River Sect were on guard.

Seeing Tang Chen return safely, everyone secretly breathed a sigh of relief.

"Senior brother, what kind of monster is in front of you?"

Tu Zhantian asked, and the others also looked at Tang Chen curiously, wanting to hear what he had to say.

Tang Chen didn't hide it, and introduced the appearance and characteristics of this monster to everyone in detail, such as their initial appearance, they can change into various shapes, and even become his appearance, ordinary star power attacks can't kill them, but thunder star power can easily kill them......

After hearing this, everyone couldn't help but be amazed, and at the same time, they became more vigilant, imagine how dangerous it would be if a monster turned into a disciple of this sect appeared beside them!

"Senior brother, this kind of monster can not only change its appearance, but also imitate even soul power fluctuations, how can this be prevented?"

Someone couldn't help but ask, and many disciples echoed it, this is indeed a very important issue, related to the safety of each of them.

Tang Chen lowered his head and thought for a while, then replied, "In this way, I will leave a special soul mark on each of you's body, this soul mark will be supported by the thunder star power, and that kind of monster should not be able to imitate."

To be on the safe side, from now on, everyone will no longer identify people based on their appearance and soul power fluctuations, but to see if the other party has this soul mark on their body. ”

Hearing this, everyone applauded.

Tang Chen did not hesitate, and immediately started to condense the soul seal and attach it to everyone's brain. With this soul seal, not only would it help everyone identify each other, but no matter how far away, Tang Chen could sense their location, and even whether they were in danger.

After doing this, Tang Chen originally wanted to refine a thunder-attribute defensive star rune for each person, but unfortunately he didn't have so many thunder-based materials on his body, so he had to give up.

Then, they began to move and continued to move forward.

I traveled more than two hundred miles, and I didn't encounter the same monster as before, but I didn't find any particularly valuable treasures along the way.

There is no sun, moon and stars here, and there is no day and night in the outside world, and the sky is always rippling with that dazzling aurora, without a trace of clouds.

For the Star Scholars, when they are promoted to the Star General, they can quickly calculate the time with their soul power, so even if there is no day and night here, they still know how long it has passed.

Tang Chen and the others traveled more than two hundred miles, and it was almost a day.

Although the physical strength and energy of the star people are very strong, it doesn't matter if they don't rest for a long time, it will still have a little impact on their state, in order to keep everyone in the best condition at all times, Tang Chen asked everyone to carry out the work and rest time of the outside world, hunting for treasures during the day, and cultivating and resting at night.

At this time, they came to a small lake, and if you don't consider this general black, the scenery here is actually very good, with a panoramic view of the lake and mountains.

On the map, this place is called Emperor Lake, a very domineering name, everyone looks at the scenery inside and outside the lake, but it is difficult to associate it with "domineering", and I don't know what the person who started this name thought in the first place......

"Tonight, let's camp here. ”

Tang Chen said that his soul sense had already checked the radius of twenty kilometers and found nothing wrong.

Hearing this, everyone dispersed in small teams and began to set up tents on the spot.

This kind of work, for the star, often do it when hunting stars outside the day, it can be said that it is familiar with the road, it does not take half an hour, all the tents are set up, and the planning is well organized, the warning area, the living area, the meeting area, and the rest area are all available.

The task of vigilance is carried out by ten teams in turn on a daily basis, and the specific arrangements are entrusted to Tu Zhantian, Tang Chen does not ask about these trivial matters.

After setting up camp, the people in charge of guarding were already in place, and the rest of the people were eating roasted star beast meat and cultivating as usual. After practicing for two hours, everyone began to take a nap and rest one after another.

Only then did the whole camp really fall silent.

It's just that the aurora in the sky is still dazzlingly rippling, illuminating this piece of heaven and earth, except for the quiet, there is no sense of night.

The disciples in charge of guarding the camp stood around the camp, they sat cross-legged with their eyes closed, and their soul consciousness radiated to the maximum extent, monitoring the wind and grass around them.

Feeling the silence of the night, they felt that it should be a very peaceful night, but they did not take it lightly.

Time passed quietly, and the world was surprisingly quiet, with no insects chirping or the wind blowing leaves......

Just after everyone had slept for about an hour, there was a sudden sound of dense footsteps in the distance, mixed with the "click" of some trees being slammed, and it sounded like a group of people were running in a panic, destroying the trees along the way.

Because it was very quiet here, the sound could be transmitted far away, and when the disciples in charge of guarding heard the sound, they did not see any unusual movement in their soul consciousness, which showed that the sound was coming from at least a thousand meters away.

The sound grew clearer and faster, and at first glance it became clear that someone or beast was running towards their camp.

The vigilant disciples were all on guard, and if they found that someone or beast had intruded into their soul sense, they would immediately warn them.
