This back-shaded thunder is a kind of thunder bead with great lethality made by using a kind of foul-smelling Lin powder and a variety of fire attribute refining materials.

Once it exploded, those small needles as thin as cow's hair, dense beads exploded like a goddess scattering flowers.

Monks in the foundation building period, if they don't have extremely strong protective treasures on their bodies, they will definitely be beaten into a sieve.

Even if the master of the Jindan stage does not pay attention, he will be injured by the power of the explosion.

Moreover, when this dark mine explodes, it will also produce an extremely unpleasant stench.

Once the body is contaminated by this foul smoke, it will not be washed clean in a few days.

This is a kind of yin treasure with very strong sequelae.

It was notorious in antiquity that no monk would be willing to approach him for a few days, even if he did not die.

"This is good!"

However, after Zeng Xiaoyu studied it, he let out a shy smile.

The scene of a certain master being overshadowed by the back thunder he refined has already begun to appear in his mind.

There are a lot of materials needed to refine the shadow mine.

However, Zeng Xiaoyu has obtained a lot of refining materials in recent times.

Together, they actually gathered most of the materials for refining the back shadow thunder.

Except for the foul-smelling powder, everything else is complete.

This kind of powder is just a special kind of agricultural powder, which is generally used to repel poisonous snakes.

Therefore, Zeng Xiaoyu just asked someone to go to other counties to buy a large barrel back.

took this large bucket of Lin powder and flew elsewhere.

Just kidding, this powder smells extremely bad, and once opened, the stench can drift for a mile or two.

Zeng Xiaoyu didn't want to open the lid of the barrel in Zengjiabao, so as not to make the entire Zengjiabao stink.

Zeng Xiaoyu came to a place far away from people, dug a cave on the cliff, and then entered the cave and began to develop this shadow thunder.

This is Zeng Xiaoyu's first refining weapon, and although the back thunder to be refined is not a magic weapon, its refining process is also quite complicated.

Fortunately, this kind of thing is just a disposable product, and the requirements for the purity of the material and the refiner are not too high.

As long as you strictly follow the refining steps of the shadow thunder and don't make any mistakes halfway, you can refine the shadow thunder.

......

More than half a month later, Zeng Xiaoyu flew out of the cave with joy on his face.

At this time, there were already nearly fifty back-shadowed thunders lying in his storage bag.

There are so many backing thunders, enough for him to use the yin people many times.

However, Zeng Xiaoyu also planned to leave half of the back thunder to the family.

After all, the power of this shadow thunder is amazing, and it can be killed even in the late stage of foundation building.

Leave some for the family, and if you meet any guy who is not long-eyed in the future, and then attack Zengjiabao, let the clansmen welcome him with a back thunder.

Anyway, as long as the formation shield is opened, the stench of the back thunder will not be able to enter Zengjia Fort.

However, although the power of the shadow thunder is huge, it is very good to use it for yin people.

However, the refining process is extremely painful, and you have to endure the stench emitted by the foul smell of the powder.

During the refining process, Zeng Xiaoyu's body was inevitably contaminated with some stench.

Zeng Xiaoyu deliberately rinsed himself with water several times, and stayed outside for a few days before daring to go home.

That taste, Zeng Xiaoyu feels disgusting and wants to vomit when he thinks about it now.

Zeng Xiaoyu decided that he would never refine this kind of thing again in the future.

This thing needs to hurt yourself first, and in the process of refining, Zeng Xiaoyu didn't know how many times he had vomited.

This has caused Zeng Xiaoyu to have a very bad appetite recently, and he doesn't want to eat at all.

Moreover, refining this kind of backing thunder requires a large amount of refining materials.

If other monks knew that Zeng Xiaoyu had wasted so many refining materials to refine fifty shadow thunders, I am afraid that they would have to scold Zeng Xiaoyu for destroying the heavens.

After all, although the power of these backing thunders is not bad, in the final analysis, they are just one-time things, and they are no longer used after they have been used.

With so many materials, at least you can refine several magic weapons of good quality.

But Zeng Xiaoyu didn't care.

Make the best use of things, Zeng Xiaoyu doesn't know how to refine weapons now, and it is a waste to put these refining materials in his hands and not use them.

It's better to refine them into back-shadow mines, and it's not bad to use them as a killer feature for yourself.

......

Zeng Xiaoyu lived in Zengjiabao for a period of time and left a large number of treasures, and finally under the farewell of his grandfather and parents and other Zengjiabao clansmen, he endured reluctance and left Zengjiabao and embarked on the road back to the sect.

It is true that home is a man's harbor, but the man's henjaz is in all directions.

People who are self-reliant and self-reliant, when they have a warm attachment to the family, continue to work hard, surpass themselves, and make themselves stronger and stronger, so that they are qualified and capable of guarding this home.

Although Zeng Xiaoyu is attached to this family, Zeng Xiaoyu knows very well in his heart that if he does not advance on the path of cultivation, he will retreat.

If he is just a cat enjoying himself at home, he will be surpassed or even crushed by others sooner or later.

Someone once said: When the times abandoned you, they didn't even say hello.

Therefore, in order not to be surpassed by opponents, in order not to be abandoned by the times, Zeng Xiaoyu cannot slack off.

......

"Senior Brother Zeng, if you don't go to watch the Outer Gate Dabi, where are you going?"

Zeng Xiaoyu had just returned to the Tiankun faction and was rushing to his cave mansion, when he met his neighbor Zhang Chunhua on the way.

As soon as Zhang Chunhua saw Zeng Xiaoyu, his eyes immediately lit up, and he greeted him with a smile on his face.

After all, Zeng Xiaoyu is now in the outer door of the sect and already belongs to a celebrity.

The first disciple in the history of the sect to successfully enter the sect through the back door.

The first beauty in the outer door, Yu Linglong, is the only man who has been raised.

With the strength of the late congenital stage, he was able to fight a tie with Senior Brother Ding Yaoyang in the early stage of foundation building within a few moves.

......

All kinds of brilliant achievements passed through Zhang Chunhua's mind.

Although Zeng Xiaoyu's road to fame seems to him to have some disgraceful elements.

However, Zeng Xiaoyu's strength is real.

Just ask, among the so many innate late-stage disciples of the outer sect, which one can be compared to the one in front of him?

And go through the back door and be raised, you also need to have a background and capital!

Therefore, Zhang Chunhua's eyes when he looked at Zeng Xiaoyu at this time flashed with admiration.

He also wants to be fostered, but his appearance doesn't allow it.

"Has the triennial outer door competition begun?"

Zeng Xiaoyu was stunned when he heard this, and looked at Zhang Chunhua, who looked adoring, and asked.

When Zhang Chunhua heard this, his face showed great surprise, and his eyes widened and asked, "Don't you know that the Outer Gate Contest has come to an end?"

Zeng Xiaoyu shook his head with a wry smile and said, "I've been practicing outside for a while now, but I don't know much about what is happening in the sect!"
