I let you cultivate immortality, not bring harm to the immortal cultivation world!

Qin Yu was not obsessed with increasing the power of the ball. The current power was enough. If it became stronger, Qin Yu would not be able to control it.

However, Qin Yu also had to find the defects that should be found.

Qin Yu spread his consciousness and found five fragments.

The remaining fragments were either embedded in the rocks or flew far away, and Qin Yu had no way to find them.

Observing the five fragments, Qin Yu found several shortcomings.

First, the melting point of the iron sheet was too low, and it melted under the full heating of the fire element.

Second, the strength of the iron sheet was too low. These five fragments showed signs of deformation to some extent. If the power was greater, they might be damaged when they exploded.

These two problems are easy to solve, just change the material directly.

The most fatal problem is that the iron sheet is too small. Even if it hits the enemy, it cannot cause enough trauma.

For example, Qin Yu was hit, but he was almost healed after taking a healing pill. If he was replaced by a Yuanying stage cultivator, he might be healed in the blink of an eye.

But if the iron sheet is enlarged, not only will the power be reduced, but the attack range will also be much smaller.

Qin Yu has three solutions to this problem.

First, poison!

Apply poison on the iron sheet. Once it hits the enemy, it will poison the enemy.

Second, increase the attack effect.

For example, engrave a formation that is harmful to the spirit on the iron sheet. Once it hits the target, it can attack the soul while attacking the body.

The higher the realm of the cultivator, the more important the soul is. The second method must be more powerful.

Third, the above two methods are not contradictory when used together.

Qin Yu wants to use this thing as a trump card, and it is very reasonable to have multiple powerful effects.

However, poisoning and adding other attack effects can be added after the ball is made, and Shi Yi does not need to know.

After the test, Qin Yu flew away from the cliff and flew towards the Refining Peak.

He explained the details to Shi Yi. Because the material needs to be changed, the price of an iron ball will increase by 500 spirit stones.

Qin Yu readily agreed and officially named the iron ball "steam explosion ball"!

......

Another day later, Senior Brother Gao sent a message saying that Qin Yu's task had been taken over by someone else.

Qin Yu always leaves his address for Senior Brother Gao in the outer sect. It can be said that Senior Brother Gao is Qin Yu's agent in the outer sect.

Qin Yu replied casually. These are all trivial matters to him.

And today, Qin Yu is going to do something big.

He is going to the Body Refining Peak to learn a spell to increase body surface defense.

After Qin Yu was easily pierced through the shoulder by a piece of iron yesterday, Qin Yu realized another shortcoming of his.

Defense is too weak.

The strongest body surface of Xuantian Sect is the Body Refining Peak. They focus on physical training and emphasize breaking all methods with one force. Whether it is strength or defense, they are far superior to other systems of immortal cultivators, but speed is an obvious shortcoming.

Therefore, body refining cultivators often have to learn one or more control system spells.

For example, the seventh elder, the master of the Body Refining Peak, learned thunder magic.

When fighting, first numb the enemy with electricity, and then chase him and beat him up.

Qin Yu came all the way to the Body Refining Peak. On the road, there were muscular men carrying small hills running around.

The body-refining cultivators pay attention to constantly pushing their own strength to the limit, and then rejuvenating and improving their strength bit by bit.

This is a long process, the progress is very slow, and there is no such thing as sudden enlightenment.

But the body-refining cultivators also have advantages, that is, they will not stagnate in their cultivation due to insufficient understanding.

Even if you cannot advance to the foundation-building stage, as long as you insist on exercising every day, your strength will increase little by little, and eventually you will beat other cultivators in the Qi Refining Realm.

Moreover, the body-refining cultivators with lower realms do not need any natural treasures.

In one word, save money!

Qin Yu did not come here to seek body-refining skills. If he trained himself into a muscular man, his Xuantian footwork would be learned in vain.

He was just looking for a defensive spell that was strong enough.

Qin Yu found the person in charge of the Body Refining Peak to explain his intentions, and the disciples of the Body Refining Peak immediately copied two powerful spells for Qin Yu.

Qin Yu wanted to give money, but the honest disciples of the Body Refining Peak firmly refused.

"If you give me more contribution points, I will beat you!"

Qin Yu was very moved.

And kept repeating in his heart: "Damn Shenyou Peak, profiteer!"

Qin Yu took two spells back to the cave to study carefully.

The first spell is called "The Secret of Body Refining", which is divided into two parts, one is how to increase strength, and the other is how to increase defense.

Qin Yu values ​​the latter part.

The second spell is called "Rock Transformation". As the name suggests, the skin will turn into the color of rock and be indestructible when this spell is used.

Qin Yu also has a pill with similar effects.

Qin Yu's version of the strengthening pill, after taking it, it turns into rock and is indestructible. The disadvantage is that it can only be restored after the effect of the medicine disappears.

Qin Yu has never used this pill, because this pill really turns people into stone, thus becoming a living target. If the enemy breaks the stone arm, the arm will be gone after recovery.

And "Rock Transformation" only increases the defense of the skin surface, during which you can move and counterattack freely, and it will not turn people into stone.

‘The Secret of Body Refining enhances the permanent defense of the skin, and Rock Transformation enhances the short-term defense. Practicing these two spells at the same time will definitely increase my defense by a large margin. ’

‘It’s just that the names of these two spells are too ordinary. Alas, the author of these spells is really bad at naming. ’

Qin Yu complained in his heart, and then he turned into a ruthless training machine and began to practice without emotion.

Time passed day by day.

On this day, Qin Yu received a message from Shi Yi on his voice transmission jade pendant.

The steam explosion ball has been improved, and Qin Yu was asked to go over to see if he was satisfied.

Qin Yu was still very concerned about this matter, and immediately went to the Refining Peak.

As an old craftsman, Shi Yi, although his cultivation was average, his craftsmanship was really amazing.

The finished product made Qin Yu very satisfied.

Qin Yu immediately paid the deposit and asked Shi Yi to make him 50 first.

After experiencing the last instant speed pill shortage incident, Qin Yu suffered from resource shortage phobia. Now, regardless of whether it is useful or not, the Qiankun bag is full.

‘I have to go to Wang Shuai to clean up the inventory some other day. There are too many things in the Qiankun bag. ’ Qin Yu thought as he walked towards the Sutra Library.

He wanted to poison his steam explosion ball and draw a formation that could attack the soul.

And he would not meet these requirements.

At this time, Qin Yu instinctively thought of the figure of the all-knowing know-it-all who could get something for free.

If he didn't get something for free now, when would he?

Qin Yu came to the Sutra Library, took out a piece of paper given to him by the know-it-all, and wrote on it:

"Are you there?"

The know-it-all: "When?"

Qin Yu: "I'm at your door!"
