Tianyu Alchemy Lord

What the Liu family wants is a permanent passage through the Yana Mountains, not a temporary one. Otherwise, they could find a way to kill a weaker beast among the eight.

But if they do this, it won't take long before a new beast king of the same level appears and becomes a stumbling block again.

Therefore, only by completely occupying the Yana Mountains can they solve the problem once and for all.

Su Chen laughed: "Master Liu just said that I am not a match for any beast king of the sixth level of the Return to One Realm. Why do you suddenly need me to help again?"

Liu An laughed: "That makes sense."

Liu Ding said: "My Liu family has developed a weapon with amazing power that can kill the top sixth level of the Return to One Realm. However, that weapon requires extremely pure thunder attribute ore to operate. According to the current progress, it will take more than a hundred years to successfully extract thunder ore of this purity. Therefore, we need you to control this weapon."

"From your point of view, once you leave the Yana Mountains, it is the Qiongguang Plain, where strong people are everywhere, and it is impossible to gain a foothold with the cultivation of the fifth level of the Return to One Realm."

Liu An continued, "But if my Liu family can pass through the Yana Mountains and gain a foothold in the Qiongguang Plain, we can become your backing."

"Think about it."

In fact, if Su Chen wants to pass through the Yana Mountains, he only needs to wear the Void Array Armor, and he should not be discovered by the beast king.

However, Su Chen wanted to see the so-called killer weapon. If it could really kill the sixth level of the top level of the Return to One Realm, and if he could steal it, then he would have another killer weapon in the future.

"If the so-called killer weapon is really so powerful, let's cooperate."

Su Chen said.

"Okay."

The two Liu family members smiled at the same time.

Soon, Su Chen saw the killer weapon.

This is a crossbow, equipped with only three arrows.

The materials used to make the crossbow body and the sword body are extremely rare. It is obvious that they are high-level materials that the Liu family has spent a lot of effort to collect.

Energy needs to be injected into the crossbow to push the arrow and burst out terrible destructive power.

And the source of this energy is thunder ore, and it is not the kind that is mined, but purified.

Because this crossbow needs to input a large amount of energy in a short period of time to maximize its power, which requires too high energy purity.

Originally, this crossbow was supposed to be powered by several Liu family members who were at the sixth level of the Return to One Realm in the early stages of design, but after it was built, it was discovered that they could not activate it at all. Even if they did, the effect would be far from what was expected.

As for Su Chen, although he was only at the fifth level of the Return to One Realm, his thunder energy was very pure, so maybe he could.

Of course, because that was not Su Chen's power at all, but Shen Yan, the source of all thunder ores.

If even Su Chen couldn't do it, then no one in the world could activate it.

Su Chen put an arrow on the crossbow and injected power into it.

Energy flowed in bit by bit, and there was an energy pool in the crossbow, which was now slowly filling up.

After the energy pool was full, Su Chen waited for a while before aiming at the target in front and pressing the switch.

"Boom!"

An arrow shot out.

As fast as thunder in the sky, it left a trail of electric marks.

Then, there was a loud bang, and a mountain in front was flattened.

For a moment, Liu An, Liu Ding, and several other Liu family members who followed them all opened their mouths halfway, completely speechless.

This attack was simply earth-shattering.

"It is estimated that the power has reached the early stage of the seventh level of the Return to One Realm."

Liu An speculated, because he had never seen the seventh level of the Return to One Realm, and could only imagine it according to his martial arts level.

"Killing the top sixth level of the Return to One Realm is a piece of cake."

"It takes no effort to flatten the Yana Mountains."

"Haha, who else can compete with my Liu family now?"

The people of the Liu family were extremely excited, and someone immediately went to retrieve the three arrows.

Even Yun Xi was very shocked. She didn't expect that this crossbow could exert such a terrifying power in Su Chen's hands.

"Friend Zhang, happy cooperation."

Liu An smiled and stretched out his hand.

Su Chen also stretched out his hand and shook hands with the other party.

Of course, he would not work for the other party for nothing. Although he also had to pass through the Yana Mountains, it was natural to ask for some benefits and he couldn't be soft-hearted.

The Liu family also knew the value of Su Chen. After all, without Su Chen, the crossbow could not be activated at all. They sent many spiritual medicines to Su Chen and promised to share the gains with him after conquering the Yana Mountains.

After the two sides reached a cooperation, the Liu family began to contact other outsiders, hoping to pull them all in to cooperate.

This is a win-win situation, so outsiders also joined in one after another to flatten the Yana Mountains with the Liu family.

"Brother Zhang, do you really believe in the Liu family?"

Yun Xi came to Su Chen, calm and elegant.

Su Chen knew that this girl seemed to be out of touch with the world, but in fact, she was very cunning and had many little thoughts.

Su Chen smiled: "Why don't you believe it?"

"I heard that there are many rare spiritual medicines in the Yana Mountains, some of which can even make the sixth level of Guiyi Realm go one step further. Do you think the Liu family is willing to give up such a treasure?"

Yun Xi said with a slightly parted lip.

According to the Liu family, they are willing to share the harvest from the Yana Mountains with Su Chen, so when it comes to the spiritual medicines of the sixth or even seventh level of the Guiyi Realm, they will naturally share them equally.

But will the Liu family be willing to do so?

Su Chen smiled lightly and said nothing.

"Brother Zhang, I just want to remind you that the Liu family will never be so generous."

Yun Xi said and walked away gracefully.

Of course Su Chen would not trust the Liu family, but he would not give up on cooperation. The Liu family's crossbows were tailor-made for him. If he did not get them, he would not give up easily.

After a day of preparation, the Liu family mobilized everyone on the road and set off towards the Yana Mountains.

The Liu family has been waiting for this day for hundreds of years, and generations of people have worked hard for this day, which has become a long-cherished wish.

After walking for two days, they arrived at the foot of the Yana Mountains.

This mountain is so high that it can reach the sky, and there are clouds and mist on the mountainside.

"hold head high!"

"Ouch!"

Before he even got close, he could already hear the roar of animals and the chirping of birds, which penetrated straight into his soul and chilled his soul.

There are king beasts at the sixth level of Guiyi Realm here.

"Be careful, the monsters are not the only ones you need to guard against, there is also the environment here that you need to guard against."

Liu An reminded, "There are some plants here that may seem inconspicuous, but their needles are designed to break through the defense of the true essence. Once they are stung, the poison will turn the person into rotten blood in just a few seconds." "

Everyone was shocked when they heard what Liu An said. Fortunately, everyone was prepared when entering the secret realm. They had already put on armor, which should be able to withstand some needle pricks.
