The two walked with a grin all the way, and they also learned each other's family background from each other's words. Zhao Hu is a direct descendant of a second-rate family in Yongzhou City in the northwest region, and his family background is slightly stronger than Chu Changqing. Coming out this time is also a kind of tempering for him by his family.

As they went deeper, they gradually noticed that the scenery around them gradually began to change. From the gray aura at the beginning, it has gradually become a dark black aura, and even the soil on the ground has become dark black. On the flat land, some tall and towering plants appeared, and these plants shimmered in light and shone brightly, shining all over the earth.

Occasionally, some reptiles such as poisonous insects or scorpions appeared, but all of this was easily avoided by Chu Changqing and Zhao Hu. Although these animals are not much of a threat to them, the two do not provoke them in any way. With a wary expression, he walked slowly.

"Shhhh Hiss!" Suddenly, an extremely slight sound came, and Chu Changqing's heart immediately felt a powerful danger. I didn't want to think about it, I brushed it, my body changed, and the short knife in my hand was lifted up, and it directly hit the slender figure in the air.

"Poof!" The sharp short knife slashed directly into the figure, and a splatter of blood spurted out, forming a beautiful pattern in the air.

"Step, step!" two corpses as thick as a baby's arm fell from the ground, shrinking on the ground.

Carefully looking at the corpse on the ground that was cut in two by himself, Chu Changqing found that it was actually a snake with a whole body as black as ink, and at a glance, he knew that it was highly poisonous, and once it was bitten, I was afraid that he would die in a moment. After making a careful gesture to Zhao Hu behind him, the two slowly walked towards a hill about dozens of meters high on the right.

"Quack!quack!" Suddenly, a sound similar to the chewing of a beast came clearly into their ears after Chu Changqing and the others climbed the hill. When the two heard the sound, they glanced at each other, and they both saw a strong curiosity in each other's eyes. Without saying a word, the two of them quickly lowered their bodies and slowly walked towards the source of the sound.

When they reached the back of a rock, they saw a large black figure squatting not far away. Stretching out its pitch-black sharp claws, it cut a large hole in the ground and devoured things. A pair of blood-red eyes are filled with a violent bloody and cruel aura, what is it not an underground demon!

"Big brother, the underground demon!" Zhao Hu exclaimed in a low voice, with an excited look in his eyes, this was the first time they had met an underground demon after they had been walking for a day, no wonder he was excited. "What should I do, do you go straight down or do you two sneak attack?"

"Of course it's a sneak attack, the strength of the underground demons is not weak, we have to stay here for half a month this time, and it is important to maintain our physical strength. Although the Underground Man Demon is an excellent training opponent, this time there is a task on our body, and we can't afford to grind. Don't do it, look at me!" Chu Changqing whispered, and as soon as his mind moved, two willow leaf-shaped flying knives suddenly appeared on his right hand.

The flying knife is no more than half a foot long, about three inches, and the whole is in the shape of willow leaves, which is made of fine stainless steel. The blade was extremely thin, and it shone with a chilling light in the dim environment.

Since coming to this life, it was the first time that Chu Changqing had picked up a flying knife in his hand, and a familiar feeling arose from the bottom of his heart. If it weren't for the special nature of this mission, he would have forgotten his old friend!

If it is about being familiar with the flying knife, Chu Changqing dares to boast that no one knows the special surname of the flying knife better than him! In his previous life, he sniped the enemy many times, all by relying on the flying knife in his hand. Flying knives in hand, I have the world!

"Flying knives?" Seeing that Chu Changqing actually took out two small flying knives, Zhao Hu was surprised in a low voice, "Big brother, are you going to use these two small flying knives to deal with the underground human demons?"

"Shhh

Not far away, the underground human demon still kept tearing open the hard ground with its claws, and pieces of metal stones of different sizes were put into its mouth and crunched and crushed. Underground metal, which is far more than the average quality of steel on the ground, is hard and self-explanatory, but it is as easy as eating candy in the mouth of a human demon.

"Whoosh!" just as the demon was about to grab the good food on the ground again, suddenly! From a distance, a brilliant meteor light shot out, as fast as lightning, and in the blink of an eye it was in front of him.

"Poof!" As if the sound of a sharp blade cutting into tofu, the human demon did not react, and the lightning had already rushed to its neck and firmly nailed to it. A trail of blood that resembled a jet of tap water spilled out.

"Uhh The blood-red eyes shot out extremely unwilling emotions, and a low roar came out of its throat, and bursts of blood foam flowed down its body, and finally fell to the ground with a bang, shrinking its huge body.

"It's... This ......" Looking at the human demon who fell to the ground in front of him, Zhao Hu's eyes showed an incredible look, he didn't believe that an underground human demon who had never had an opponent during the refining period would be killed by a small flying knife. But the scene in front of him made him unbelievable!

"Big brother! Did you really kill it with a throwing knife?" Zhao Hu's usually calm voice fluctuated at this moment due to excitement, and he stammered and asked. He only saw a bright light flying out of the dim sky just now, followed by the human demon convulsive and fell to the ground, how Chu Changqing sent out the flying knife, he didn't see it clearly at all.

In response to Zhao Hu's question, Chu Changqing smiled and did not answer directly, but quickly walked to the side of the underground human demon and pulled out the flying knife inserted in the throat of the human demon. Then without the slightest hesitation, he slashed it down, just like cutting a watermelon, but the neck of the human demon was extremely hard, and Chu Changqing took a lot of effort to cut off his head.

This underground human demon is covered with tiny scales, and its skin is very hard, and ordinary swords can only leave traces on its body, Chu Changqing fortunately uses a hundred refined steel, and the quality is many times stronger than ordinary swords.

Dissecting, searching, excavating, and Chu Changqing acted neatly, and in a moment, a diamond-shaped object about the size of a walnut and covered in blood appeared in his hand. Quickly wiped the blood stains on the human demon's body, Chu Changqing stared at the object in his hand carefully, and whispered softly in his heart: "Is this the magic crystal?"

At this moment, a diamond-shaped object the size of a walnut appeared in his hand, like gold but not gold, like wood but not wood, and the whole body was in a gray-brown state, slightly warm. Judging from the physical appearance, it is impossible to distinguish what kind of substance it is made of.

"Is this the magic crystal, it looks so strange, it's completely different from the beast crystal!" Zhao Hu muttered as he stared at the magic crystal in Chu Changqing's hand. Beast crystal is a kind of round crystal that is full of bright light, crystal clear, various, and colorful. On the other hand, the magic crystal is the opposite, gray and not slippery, without the slightest luster, nor transparent, from the outside, it is almost like a stone.

"It shouldn't be wrong, there's only one thing in its head!Didn't the examiner say that only in its head will there be magic crystals!" Chu Changqing said, casually putting the magic crystal into the Qiankun ring. "Let's go, let's go and see somewhere else!"

"Oh!" Zhao Hu responded, suddenly remembering that Chu Changqing hadn't answered his question yet, but then after thinking about it, he understood.

People have such a stunt, naturally they are made by learning cheats, even if they ask what they can do, although they are envious in their hearts, he is not jealous. Who doesn't have one or two stunts, he Zhao Hu also has it! However, that flying knife is indeed very powerful! With a "whoosh", the human demon fell to the ground!
