Sandworms have a special ability. The mucus secreted on the surface of the body can stick to the sand and gravel. Before the mucus drys out, these sticky gravels have extremely high strength. In addition, the circular channel shape disperses the pressure, and these channels can often withstand tens of thousands of tons of pressure without collapse.

The people from the Jia family used this principle to create a sandworm excavator. After the sandworm excavator was activated, the sandworm became larger and could accommodate people to drill into the body. In this way, the sandworm became a fairy-tale version of the shield machine, and only Jia Ziqi needed to operate it to dig the hole and move forward.

The half-biological and half-puppet sandworm excavator does not require too much mana operation, and the excavation speed is also OK. While waiting for it to dig and pass, Zhang Ying and Jia Ziqi can still drink tea and chat in the sandworm's body.

I didn't drink many cups of tea, and suddenly something came from my mouth. Even if the sandworm was refined into a half-puppet, its instinct for swallowing was not lost. It would still swallow it when it encountered substances that were useful to it.

The swallowed things naturally fell to Zhang Ying and the others. Jia Ziqi took the thing clearly. When the two saw that they were rustic crystals weighing more than one pound.

"Haha, this is a piece of yellow sand aura crystal, which is considered an unexpected joy." Jia Ziqi said. Immediately afterwards, this unexpected joy continued to appear, and the sandworms continued to swallow the yellow sand aura crystal, as well as various strange spiritual gems, most of which are earth-based.

"It is worthy of being underground in the sand sea, there are many crystal gems here." Jia Ziqi sighed. In just one hour, he received dozens of kilograms of yellow sand crystals. No wonder Jia Gong's cultivation level improved by leaps and bounds after he returned.

However, these crystals are not very useful to Jia Ziqi, who is at the ninth level of Qi training, so they can only trade them out or use them for other people in the family.

Zhang Ying asked curiously: "There will be so many crystals?"

Jia Ziqi smiled and said, "Any crystallization of gas requires a place where the gas is thick and high pressure can be formed. Therefore, crystallization is usually produced underground. Of course, there are special formations among various major sects that can suppress crystallization, which is the safest way to produce it."

Zhang Ying suddenly realized and thought about why his Huju Temple had not been produced in the crystallization.

Well~~~The place where Huju Temple is located has all kinds of energy, and nothing is strong. It is impossible to set up a large array to suppress crystals. There is a ghost eye underground, and the ghost energy should be able to suppress the crystals of ghost energy.

But what is the use of suppressing the crystallization of ghost energy? The ghost cultivators in the sect are not short of ghost energy when they practice on the ghost eyes. Why do they need to crystallize and practice? Crystallization is just a collection of qi, which is more efficient than absorbing free qi to practice. The ghost eyes are full of ghost energy, and whether there is crystallization does not affect the efficiency of practice at all.

If it is sold, before Zhang Ying's trade point in the Rosewood Kingdom appeared, the monks in Huju Temple almost did not do business with outsiders.

If you think about it carefully, the place where Huju Temple is located is really a broken place. It has beautiful mountains and rivers and is easy to support people, but it is of no use to monks. It is not a Buddhist monk, so who do you want?

I don’t know how long it took, the sandworm stopped. At this time, Jia Ziqi also collected hundreds of kilograms of yellow sand crystals, as well as various gems, spiritual materials and other things. These things will be accounted for after they go out.

Outside the sandworm's body, it was pitch black outside, and there were no luminous particles in the air. Only the faint roaring sounds behind him were heard. Jia Ziqi took out a night pearl and hanged it on her head. The misty light illuminated the three feet of the range around her.

This is the edge of the sea of ​​sand, next to it is huge stones, no longer sand. A winding path appeared in front of the two of them.

"This is an underground crack, through which we can reach our destination. However, there are hidden monsters in the crack, so we must be careful."

Zhang Ying nodded and skillfully took out a few double-level Vajra Talismans from his arms. He divided several double-level Vajra Talismans for Jia Ziqi, and then put a few Vajra Talismans and other talismans on Chi Chao.

Looking at Zhang Ying's cautious look, Jia Ziqi wanted to speak but stopped. Forget it, he didn't understand the rich world.

The two of them walked into the crack, and Zhang Ying suddenly said, "There is no suffocation here, the air seems to be sufficient."

Jia Ziqi said depressedly: "This place connects to that secret realm, and there is naturally no shortage of air."

At this moment, Chi Chao suddenly roared at the darkness, and then the whole tiger pounced at the darkness. Zhang Ying only heard a "crack" sound in the darkness. Not long after, Chi Chao dragged out a monster.

The monster was hairless, with limbs on the ground, with developed front paws. What's even more peculiar is that it has no eyes and surprisingly big ears. There is only a small black dot in its eyes, which seems to have degenerated.

"This is the monster in the crack. The powerful one has the late stage of Qi training, and it seems that there is no foundation-building stage." Jia Ziqi introduced.

If there is a foundation-building stage, his father will die here at the beginning.

"This kind of monster acts like the wind, and is very good at ambushing others in the dark, and its claws are poisonous. But it seems that it is being restrained by your Xuanhu now." Jia Ziqi said with a smile.

Tigers are also hunting masters in the dark. When two old men are together, it depends on who is better.

The red tide sneaked into the darkness, and only a faint spell aura can be seen. However, this hairless monster has no vision at all, and they cannot see even if there is spell aura.

At this moment, Zhang Ying's pearly golden cloud cover suddenly activated, blocking a monster that jumped down from the top of his head. Zhang Ying immediately threw out a sword energy. The monster was obviously blocked by the pearly golden cloud cover and was instantly hit by Zhang Ying's sword energy.

The sword energy in the hurry could not kill the monster, but just cut off its front paws. The monster made a "whimper" scream and fled in a hurry.

"This thing is called companions, we have to be careful." Jia Ziqi said, and a flying stone the size of a fist condensed in his hand, which was stored without firing.

Sure enough, not long after, a rustling sound came from the darkness, the sound of claws and stones colliding, followed by a loud "受受受受". Dozens of monsters appeared in front of Zhang Ying in an instant. The leading monster had a larger body shape and a deeper skin color.

The huge claws grabbed Zhang Ying with cold light. After a closer look, there was a yellowish-colored aura on his claws. Obviously, this was blessed by spells.

Monsters are different from monsters. Monsters' spells are gifted spells, which are emitted by their own blood and energy. Monsters can be comprehended or learned, relying on magic power rather than qi and blood.

Monsters can also advance to monsters in the foundation building stage, and after the little monster builds the foundation, both are the same. It is equivalent to the result of two paths. However, the foundation building of monsters is difficult. They benefit from the strong bloodline of monsters in the early stage, but it is very difficult to build the foundation building. Monsters evolved from beasts, and even if they become little monsters, it is quite difficult. After all, they do not have any bloodline to strengthen their strength. However, they will be much easier to advance to the foundation building stage than monsters.

The monster in front of you is a kind of monster. Their spell is talented spells, driven by blood. The stronger the monster, the more powerful it is.

With a 'sweet', Jinyunqiao collided with the spiritual claw, and Zhang Ying also took the opportunity to emit a sword energy. The slender sword energy cut through the skin of the monster in front of him and cut off half of his arm.

Jia Ziqi beside him also fired the flying stone in his hand. The flying stone was like a cannonball and directly repelled the monster.

The monster's attack was just the beginning. Then several monsters rushed up and grabbed and scratched the Jinyunmao. Jia Ziqi's flying stones flew out one after another, killing the monsters back.

The monster "Yingyingyingyingyingying" rushed up unyieldingly. Feishui could only repel monsters, but could not kill them. It was Zhang Ying's sword energy that was useful.

The sword energy that turns into silk threads has extremely strong cutting ability. Although the skins of these monsters can block the attack of flying stones, they cannot block the sword energy of transforming silk. Zhang Ying repeatedly pops out the sword energy.

The bright sword energy silk kept cutting off the monster. After a few breaths, many broken limbs appeared on the ground. Black blood flowed on the ground, and the monster suffered heavy losses.

"Master Zhang's sword technique is also amazing." Jia Ziqi said in admiration.

Zhang Ying smiled, and he was also very satisfied with the power of this sword energy. The strength of the eighth level of Qi training, coupled with the nourishment of the Black Tiger Hidden Sword Technique, Zhang Ying's sword energy is incomparable.

Slaughtered all the monsters that attacked, and the monsters in the dark were finally scared. They no longer dared to act rashly and began to retreat slowly.

Zhang Ying and Jia Ziqi strode forward. As they moved, the monsters in the dark were frightened and retreated step by step, and finally disappeared into the darkness. This kind of monster's body was useless, and it was useless to kill more. As long as they didn't come to cause trouble, Zhang Ying was too lazy to chase them.

After a while, Chi Chao slowly walked back from the darkness. He yelled, saying that the monster in front had been solved by him.

The two continued to move forward.

"According to my father's notes, there is also a monster here. It is a monster similar to a bat flying. This kind of monster is even more difficult to deal with." Jia Ziqi said.

"I'm very curious about how Jia Gong passed through these dangers at the beginning." Zhang Ying asked curiously.

"I don't know, my father's notes do not say this. Most of them are dangerous introductions. Maybe my father is lucky." Jia Ziqi thought for a while and said.

Sometimes, luck is also a kind of strength.

Sure enough, in the following time, another group of flying monsters similar to bats attacked.

These monsters have certain advantages in reliance on their ability to fly. However, these are useless to Zhang Ying and Chi Chao. This is a narrow underground crack. So what if they can fly? In the end, they were killed by Zhang Ying and Chi Chao's sword energy, leaving behind corpses on the ground in a hurry to escape.

These bat monsters are like hairless monsters and have no use at all. Moreover, their blood and energy are not strong, and they are not even qualified to refine Blood and Qi Pills.

After walking for a long time, a ray of light suddenly appeared in front of me. The road ahead was covered with clusters of glowing crystals. Jia Ziqi also said, "The road below is beginning to become dangerous. Those glowing crystals are very dangerous!"

Zhang Ying couldn't help but look at the crystals in front of him again. The crystals shone brightly, illuminating the passage as bright as daylight. He didn't know where the danger was.
