Force warriors and Force gods enter the Bone Dragon Path of the Underworld. The purpose is to obtain the True Soul Yuan Crystal and enhance the strength of the soul.

After all, the soul is so important to an Force Warrior practitioner that it is the heart of an Force Warrior.

Therefore, any Force warrior or Force God of War, the first time they obtain the True Soul Yuan Crystal, they will devour and absorb it to increase their soul strength.

When you obtain the True Soul Yuan Crystal and don't use it yourself, there is generally only one situation, that is, the soul strength has reached the limit.

Soul Strength Limit!

Lin Yu didn't know if there was such a word in other places, but "soul strength limit" was very common among the Holy Purple Source Planet, the Human Race, the Zerg Clan, and the Desolate Beast Clan.

Each Force warrior increases his soul strength with the gradual use of True Soul Crystals.

When the soul strength reaches a certain level, the soul strength will reach the limit and cannot be enhanced again.

When the soul strength reaches the limit, it is natural that the True Soul Yuan Crystal will no longer be used.

And Nata Erzhi, obviously, its soul strength has reached its limit.

At this time, the six True Soul Yuan Crystals in his spatial ring were the best proof.

"Six!"

With a flip of his hand, the six True Soul Yuan Crystals were all taken by Lin Yu into his hands.

Looking at these six bright True Soul Yuan Crystals that were like stars, light purple and tranquil, and met Lin Yu's eyes, Lin Yu had a feeling of soul wandering.

"This True Soul Yuan Crystal is worthy of being a top-notch treasure, just looking at it, it can make the soul throb."

"Little Bud, what is my current soul strength?"

Before Lin Yu was about to absorb it, he asked Xiao Ya again.

"Your current soul strength is 114."

The strength of the soul, with the cultivation of the Force warriors, will also gradually increase, gradually enhanced. But this amplitude is low. It is far less than the anti-heaven effect of the True Soul Yuan Crystal.

"One hundred and fourteen, compared to when I first entered this underground world, it has not increased at all." Lin Yu said secretly.

Immediately, holding a True Soul Yuan Crystal in his hand, he entered the unified static Lin Yu, and the Force penetrated in, and Lin Yu began to carefully devour these True Soul Yuan Crystals to increase the strength of his soul.

…………

Bone Gangside Dragon Road, deep in the cave.

A burly man with a cloak and a burly figure was sitting cross-legged and practicing, and around his body, there was a rather rich metallic charm, faintly circulating.

"Huh?"

Suddenly, the burly man's expression moved slightly.

Immediately, the man looked at the "Boundary Soul Mark" on his wrist, and then the burly man frowned.

"Tuo Er Zhi is dead?"

Although Na Tuo Erzhi, in his opinion, is a casual crush, but at least it is also his subordinate, and the dead are still to be taken care of after all.

"Call Yunhu." The man said softly.

After a few moments, the Force Band connects the call.

In the underground world, the Force information of the Force Bracelet can only be transmitted for a maximum of five or six hundred miles. Obviously, the Force practitioner named Yun Amber was in the range.

"Brother Dunshan, what's wrong?" A refined man's voice was heard.

"Toechi is dead." The man named Dunshan said succinctly.

"Dead? How did he die? Yun Hu asked suspiciously.

"I don't know, so I'll let you check it out, be careful, maybe the master is coming. After all, during this time, Na Tuo Zhi can kill a lot of Force warriors. Dunshan commanded.

"Okay, I see, I'll be careful."

"Hmm!"

Immediately, the call was over.

After thinking for a while, this burly shield mountain once again entered the wonderful realm of the unity of heaven and man, and carefully began to feel the metallic charm around him.

…………

In the absorption of the True Soul Yuan Crystal

Hours passed quickly.

"Smack!"

With a crisp cracking sound.

The sixth True Soul Yuan Crystal shattered into powder in Lin Yu's hands.

Slowly, Lin Yu opened his eyes, and the eyes were as quiet and deep as the dark night sky.

His gaze swept over the surrounding world serenely, and after a moment, Lin Yu laughed.

"Little bud, what is my soul strength now."

"Your current soul strength is 144." Xiao Bud's voice sounded crisply.

"One hundred and forty-four, an increase of exactly thirty points. The feeling of soul enhancement is really good. Feeling the subtle manipulation, Lin Yu, who was able to manipulate the Force more carefully, smiled lightly.

"I don't know, what is the limit of my soul strength." Then Lin Yu thought secretly.

The limit of soul strength of each Force practitioner is different.

As far as Force warriors are concerned, some people's soul strength limit is only 200, while some people's soul strength limit is 300. Even, some people's soul strength can reach five hundred.

Overall. In the Force warrior class, the soul strength is generally between two hundred and five hundred.

However, what is certain is that the more talented you are in terms of perceiving the natural charm of heaven and earth, the higher the limit of soul strength will be relatively speaking.

"Now, my soul strength has increased so much, let's try that 'Nine Swords in One' and see if I can close them."

The mind moved.

Zizi –

Lin Yu's purple thunder arc shone around him.

At the same time, nine thundering knives flew out from behind Lin Yu, and then bathed in a shining thunder arc.

Nine knives in one, it is a move, and it is also a basic knife style.

As a basic knife style, then it does not participate in any other form of verve, and purely relies on the ultimate perfect use of the Force.

Yes!

Nine knives in one, relying on the powerful force manipulation.

After the thunder arc was refined, it gradually dissipated, and at the same time, the thunder attribute charm also dissipated.

Instead, Lin Yu's force seeped out,

These force, which were as delicate as hair, were manipulated by Lin Yu and shrouded towards the nine thunderous thunderstalks.

The first weight of the Thundering Knife Technique, when manipulating the Thundering Knife, the Force is divided into twelve strands.

But now, Lei Ming has entered the second level, and the manipulation of the knife technique has become one hundred and twenty strands.

Nine knives, each of which is a hundred and twenty strands of subtle force.

One thousand and eighty strands of subtle force, under Lin Yu's manipulation, fused perfectly and meticulously with the nine battle knives.

If it was before, Lin Yu would definitely not be able to manipulate so many forces in detail, but now the soul strength of the soul is already so strong. Naturally, it can be manipulated.

Under the operation of the mental method, in the shroud of the force, the nine thundering knives gently closed towards the center.

"Buzz ......"

As soon as he moved closer to the center, Lin Yu felt the powerful resistance of the thundering knives against each other.

"If you don't want to cooperate, you have to give me a cooperation."

With a horizontal thought, Lin Yu manipulated the Thundering Knife to converge towards the center.

Buzz –

The more you compress towards the center, the stronger the resistance becomes.

With the operation of the Thunder Arc Heart Method, Lin Yu intensified the supply of the Force.

"Give it to me."

Suddenly, Lin Yu let out a low roar, and the power of manipulation completely exploded, frantically compressing the nine thundering knives towards the middle.

Buzz –

The nine thundering knives slammed into the center.

Immediately, there was a sound of "Peng-".

Nine thundering knives exploded at the same time.

Nine knives in one, failure!

"Hey, failed!"

Lin Yu sighed, and immediately the thundering chains surged, and all the nine thundering knives that had been blown away were gathered back.

"There's still a big gap."

In the process of closing, Lin Yu could feel that his manipulation power was still not strong enough, and the nine battle knives did not touch each other, let alone merge with each other.

Nine knives in one!

Under the operation of the mental method, the nine thundering knives fused with each other's forces and fused into one.

It can make the basic power skyrocket, and then cooperate with Shen Yun, so that the power will be terrifying.

But nowadays, it can't even be fused, let alone the subsequent Shen Yun loading problem.

"Although my soul strength has increased, my soul strength is still a little too weak. Wait until my soul strength increases to about three or four hundred, and it's almost fine. Lin Yu thought secretly.

"But who will come back, in the past 20 days, I haven't found a single one, this luck is really enough."

Generally speaking, if it is normal in a month, one or two can be found, but Lin Yu has not found one in the past 20 days. Luck indeed.

"This time, I was lucky enough to kill a hunter who had reached the limit of soul strength, so I was able to greatly increase my soul strength."

"It seems that it is still needed, and I will look for it slowly."

Lin Yu, who had collected his thoughts, set his eyes outside the cave.

"According to the information, these wanted Force God of War, they will all hold each other."

"There is a good chance that there will be other members of this area, so I need to be careful." Between thoughts, Lin Yu quietly climbed the cave.

Lin Yu, who came out of the cave, looked around, and what came into his eyes was a silent darkness, and a little fluorescent bloomed.

It looks very quiet.

"Let's go!"

As soon as he stepped on the foot, Lin Yu had already entered the unity static, and with a relaxed leap, he flew rapidly towards the cave in front of him.

At the moment when Lin Yu rose up, the change was steep.

A glass blue light like a mist took on the form of a dagger blade.

Instantly crossed a distance of thousands of meters and shot towards Lin Yu,

"It's not good, it's a soul attack." Lin Yu was suddenly shocked in his heart.

Lin Yu, who had a very strong perception, discovered this attack as soon as possible. At the same time, it was also judged that this attack was a soul attack.

Many Force War Gods, after their souls are strong enough, will practice some soul attack methods, after all, sometimes, soul attacks, which are very terrifying, can kill the enemy in an instant.

By the time it came out, it was too late. The speed of this glazed blue light is too fast, and Lin Yu can't avoid it.

That soul attack instantly submerged into Lin Yu's body.

Lin Yu, who was soaring, was attacked by that soul, and his body suddenly stiffened.
