The son-in-law of the first wealthy family

Chapter 750 Xuanyuan Seven Killing Formation!

"It's just that I'm only a third-rank alchemist now, and I can't refine these fourth-rank pills."

Mu Sheng shook his head, the excitement on his face dimmed.

In the past, every time he refined elixirs, he was only worried about whether the medicinal materials were of a high enough grade, but in the current situation, it was the first time that he encountered the situation that the medicinal materials were too high-level, but he could not refine them.

Even if he refines the elixir with all his strength, he can only refine the third-rank high-grade elixir at most, and there is still a long way to go before the fourth-rank elixir... However, Mu Sheng can only refine the red spirit double soul fruit into a third-rank elixir. But I feel that it is a bit too reckless.

"No matter what, let's collect it first. If this red spirit double soul fruit is properly preserved, its spirituality can last for about a year. The time is not in a hurry. If I can't refine the fourth-grade elixir within this year, I will use it again." It can be auctioned off, or it can be refined into other medicines."

Mu Sheng shook his head and said lightly.

Afterwards, he took out the transparent jade bottles from his pocket, picked up the jade shovel, carefully dug up the soil, and took out the whole medicinal material from the small pit.

Jade is mild in nature. As a container for collecting and holding medicinal materials, it can also preserve the spirituality of medicinal materials to the greatest extent.

"call……"

Just for a moment.

All the medicinal materials in the small pit have been collected by Mu Sheng into the jade bottle. In order to prevent the medicinal materials with roots and stems from being hidden in the soil, Mu Sheng also deliberately turned over the small pit, and then put them into the jade bottle. Put the jade shovel back into the backpack.

Afterwards, he put away the full jade bottle and left the quiet room.

As for the gold all over the ground at his feet, Mu Sheng glanced at it, but didn't even look at it.

After all, for him, these golds are also belongings outside his body, even if they are all added up, they are not worth a single medicinal plant in his backpack.

Walking slowly, he returned to sit cross-legged in front of the dead bones. At this moment, the soul-eating insect in the wooden box has entered the final state of sleep. Once it wakes up again, it will be the real time to break out of its shell.

According to the growth environment of the soul-devouring insect, Mu Sheng couldn't take it out rashly, so he could only stay here. However, in order to prevent others from discovering, Mu Sheng took the wooden box out of the dead bone and buried it in the box he had. Among the soils of special signs.

Only in this way, Mu Sheng felt relieved.

however……

"Crack-"

When Mu Sheng took out the wooden box, because the dead bone was holding it too tightly, under the force, a small finger bone was torn off, and some bones on the top fell in pieces.

Looking at the broken bone on the ground, Mu Sheng couldn't help but smiled awkwardly, bowed apologetically to the bone.

"Ok?"

Later, when he was about to pick up the arm bone, he suddenly felt that the touch in his hand was not quite right.

It's cold, like chalcedony, it can't be the touch of bones, but it's like special black weapon material...or array flags!

Mu Sheng pinched his arm bone, exerting light force.

"Crack, click—"

The white powder above the arm bone withered away, revealing a turquoise object that looked like bamboo, followed by an aura that seemed to not belong to this world, centered on the object, quietly permeated.

"It's not a hand bone...it's an array flag!"

There was a flash of light in Mu Sheng's eyes. This small quiet room brought him too many surprises. Before he could pause, he stretched out his hand and waved away all the coverings, allowing the object to completely restore its original appearance. .

In the palm of his hand was a turquoise flag. The flag above it was as smooth as silk, and it rose up without wind, fluttering from side to side like a flame.

Looking at the formation flag in his palm, Mu Sheng bowed again to the dry bone, said "offended", then reached out and directly took out all the bones wrapped in the formation flag inside the dry bone.

"Crack clap-"

White powder fell all over the ground, and at this moment, in Mu Sheng's hands, there are already seven crystal and bright array flags.

And at the bottom of the array flag, there is a line of small characters.

"Xuanyuan Seven Killing Formation...the fourth-order formation flag."

After reading this line of words, Mu Sheng's pupils couldn't help shrinking, following his heart, as if setting off a stormy sea, he secretly exclaimed: "How can there be such a thing on Donglin Island?"

Moreover, it is still under the Divine Pill Tower?

Mu Sheng's eyelids twitched. This formation flag can only be forged by at least a fourth-grade craftsman. The difficulty is even higher than that of Xuanbing of the same level. Moreover, there are hidden formations in the formation flag. As long as you use a special method By urging the formation method inside the formation flag, the formation flag can be driven.

And the strength of a person's stimulation is also related to the research of this person against the flag.

Although it is said that Mu Sheng has not studied deeply about the battle flags, he only simply arranges some of the most basic formation flags.

But there is no problem in urging this one.

After all, the double cultivation of martial arts, alchemy and dao is already extremely exhausting. If you add an array flag, even Mu Sheng will not be able to bear it.

"Xuanyuan, seven kills!"

Mu Sheng moved the flag and waved his hand casually.

The seven array flags were swung out in an instant, and fell in seven different corners of the quiet room in an instant, streams of incomparably condensed profound energy surged out from the array flags, condensed into the shape of small swords, suspended in the air, and the seven sharp swords The sword is facing the enemy, and the degree of concentration of the profound energy in the air is enough to make people feel thrilled!

call!

Following Mu Sheng, he waved again.

The soul-stirring little sword of profound energy completely dissipated within the formation.

"This formation should be a simplified version. It is not too simple to arrange. You only need to activate the formations in order, and then throw the formation flags, and you can instantly set up the killing formation within two breaths. "

"Moreover, the strength of this formation is also related to the attainments in the formation, but the entry requirements are extremely low. Even for someone like me who is not very esoteric in the study of formations, it is easy to activate."

"Once the formation flag is triggered... the practitioners below the fourth level of profound practitioners will surely die!"

"Even if the fourth-order profound practitioner is above, it is impossible to escape easily!"

"..."

After finding out all the functions of the formation flag, Mu Sheng withdrew his hand again, and at the corner of his mouth, he couldn't help but raise a smug smile. This Xuanyuan Seven Killing Formation is really interesting.

The operation is simple, the layout is simple, and the upper limit is not high. It seems that it is specially prepared for people who don't know how to use formations. This made Mu Sheng immediately think of Jiang Wan.

If Jiang Wan is taught to use the formation flag, then she will never have to worry about Jiang Wan's safety when she goes out in the future.

It's just that now, this flag is of some help to him, and after he reaches the fourth-order profound practitioner, he can teach this flag to Jiang Wan.

Putting away the formation flag, Mu Sheng's expression gradually turned serious.

This Xuanyuan Seven Killing Formation is so precious, if a fourth-order profound practitioner strikes, there is no doubt that he will die. If such a murderous weapon is left outside, even the Xia family in the hidden world will be alarmed by it.

It seems that the original intention of this dry bone is not as simple as it seems...

"However, you did everything possible to leave a message and hide it in the "Picture of Returning Deer in the Snow" to attract people. Today I have taken many benefits from you. If I have the opportunity, I will definitely avenge you."

Facing the dry bones, Mu Sheng cupped his hands for the third time.

Give favors to others, and cause and effect with others.

Although things like cause and effect sound a bit illusory, they do exist in the world of practice.

Afterwards, he checked the surroundings again, jumped onto the pit, and buried the pit again.

Next, he just needs to wait quietly, ten days later, when the soul-devouring insect completely breaks out of its shell.
