Chu Tianxing took one and put it in front of him to look at it, and saw that it was an amethyst-like crystal.

This thing was identified with the Gods and Demons, and the relevant introduction to it was immediately displayed in a data-based mode.

[Unstable ground-level demon crystal. There is a huge amount of energy in it, but there is also a risk of exploding at any time.

Chu Tianxing was playing with this thing with a smile, not worried that it would explode at any time.

"This thing looks like a thermal weapon in this world. "Chu Tianxing didn't attach too much importance to this thing, but he didn't want to throw it away because it really couldn't be used as a cultivation resource like spirit jade.

But on another level, it's a pretty useful 'weapon' resource.

In the Heavenly Saint Era, many strong people fell into the hands of the masters of the demon clan.

The reason why they will fall is not because the masters of the demon clan are strong enough.

On the contrary, in the same realm, the strong people of the human race are generally stronger than the demon race. The reason is precisely that the Terrans have mastered the power of the Tao.

However, the demon clan has a very shameless and despicable practice, but it is regarded as supreme glory by them......

Self-destructing.

When they found that they were about to be unable to defeat their opponents, they would explode the demon crystals in their bodies, causing all their cultivation power to burst out in an instant, and the power at that moment could even exert three or four times its own strength.

Therefore, when the Terran masters are caught off guard, they are often killed on the spot. It is also the reason why the human race and the demon race have been in a stalemate for a period of time to maintain peace.

"Civilization will still progress. Some historical processes are inevitable. Chu Tianxing played with this demon crystal, thinking about the changes in the Heavenly Spirit World over the years since Chu Danxin retreated into the earth.

First of all, the old powerhouse retreated to the Heavenly Spirit Continent and called himself the 'Heavenly Realm'.

Then there was a Shenwu Emperor who suddenly appeared in the Middle Domain and played a game of 'Dominating the World', established the 'Shenwu Dynasty', and also established the 'Shenwu Palace' to manage the cultivators of the world.

With this series of changes, Chu Tianxing seems to be simply a civilization that has entered the dark age from the primitive tribal state and is developing towards the feudal era.

If there is no external interference, it will really cause an industrial revolution and develop some 'modern magic weapon civilization'.

It's just that these are not important to him, what he just cares about is the transition of the Heavenly Spirit from 'strong individual cultivation' to 'strong collective group'.

From fighting alone at the beginning, after the siege of the Medicine King Valley by the world, it seems to have gradually developed more towards 'group fighting'. I don't know if they found pleasure during the siege of the Medicine King Valley.

"As a good young man in the twenty-first century who has come from modern times, how can I not teach you how to use thermal weapons?" Chu Tianxing sneered and weighed the unstable demon crystal in his hand.

Not transporting modern thermal weapons to the Heavenly Spirit was his bottom line - on the one hand, he couldn't get it, and on the other hand, he felt that it was useless to get it.

But that doesn't mean he won't use the Celestial Spirit's own thermal weapons against them, that is, the cliché of 'razing and razing'.

"Here's a big one, be careful. ”

Suddenly, Chu Lingling's serious reminder voice sounded in his ears.

Chu Tianxing looked ahead and saw that Chu Lingling had retreated.

A huge lion-faced bull demon with a height of more than ten feet took heavy steps, and the moving black giant peak was moving through the valley to this side.

Because of its terrifyingly large body, every time it falls, it causes an earthquake of magnitude 5 or higher on the ground here.

The rocks on both sides of the valley were rocky because of the heavy steps of their footsteps, and the rubbing of their shoulders through the valley, which caused large rocks to crack and fall from the valley cliffs, and there was a great movement in the mountain road.

Seeing such a huge lion-faced bull demon, Chu Tianxing also put away the smile on his face and said to Chu Lingling: "Take Ying'er and Sister Yan in, and release Yun Tianxue and Huang Jianxing." ”

Because the Medicine King Valley is now controlled by Chu Lingling, it is up to her to decide who she wants to accept in or who she wants to let out.

Chu Lingling immediately obeyed the order to take Liu Keying and Xu Yan, who were absorbing the rich demonic qi cultivation here, into the Medicine King Valley, and then notified Yun Tianxue and Huang Jianxing to release the two of them.

Yun Tianxue sniffed out of the medicine king valley as soon as she sniffed out of the air here, she took a deep breath and asked in surprise, "This is demonic energy?"

She was able to recognize at once that the rich power that filled the air here was demonic energy.

Huang Jianxing also observed the nearby place in amazement, and quickly noticed the huge demon clan that was moving towards them quickly.

Yun Tianxue also noticed at this time, and suddenly opened her mouth wide, revealing her snow-white teeth and pink tongue in surprise.

"Now one is to immediately set up a formation to stop this big guy, and the other is to immediately help me open this trap box and give you two a choice. Chu Tianxing said to the two of them, let them not think that he didn't know that they were just a cave room.

But it's time for them to do something after raising them for so long.

Huang Jianxing, in particular, still hasn't opened the box containing supernatural powers that he got from Emperor Guanghan.

Yun Tianxue and Huang Jianxing were suddenly embarrassed and glanced at each other.

Yun Tianxue, as a representative, said: "Master, even if you force us to do these two things now, we can't do it." It's too late to deploy the formation now, and it's too late. To say that the trap box ......"

She looked at Huang Jianxing, she actually felt very strange sometimes, strange that such a trap box was so difficult, and it hadn't been opened for so long?

Huang Jianxing noticed that his 'Snow Girl' glanced at him, touched the back of his head in embarrassment, and said, "This box uses ancient inscriptions. I don't understand the ancient inscription at all, so there's no way to open it. ”

Chu Tianxing knew that there was no drama when he heard him say this.

Because the ancient inscription is not as simple as the inscription, he has to come to this piece himself.

"Lend me all your strength, but come by yourself. ”

Chu Tianxing said to them.

As he spoke to them, the giant lion-faced bulldemon had pressed down on them.

This giant lion-faced bulldemon, whose status is definitely above the chief of the lion-faced bulldemon, has no weapons at all.

After it pressed the formation, it lifted its hooves at least three feet or more and stepped down on them with one foot, trying to crush them like a bunch of bedbugs.

Yun Tianxue's scalp was numb, and her body involuntarily leaned towards Huang Jianxing's side.

She couldn't figure out why she, the master, suddenly called her and Huang Jianxing out at this time. If you want to borrow strength, you just say no to them and it's over. She had to admit that she and Huang Jianxing were now the weakest fighting in the Medicine King Valley.

At this time, Chu Tianxing suddenly took out a pen, a one-foot black brush with a silver rod carved dragon. Huang Jianxing saw at a glance that this was a ......
