Douluo: I just awakened my martial soul, and my soul ring is 10 years old?

Chapter 56 Chen Yinzhu is ground into a needle
"Woof woof, this ring is too small, what should I do if it can't lock Mr. Dog?" Xiaobai looked at Shen Yinhuan who was locking people and expressed his doubts.

"This is it." Bo Saixi made a clever move, and a blue energy appeared in his hand, as if a big hand directly locked Xiaobai to Shen Yinzhu.

"I'll do it myself." Huanlu pouted and consciously walked up to the Shen Yin Zhu. The five Shen Yin rings on it clasped her thin body at the same time, fastening them on her neck, waist, feet and two At the wrist.

Fix Huanwu's whole body firmly on Chen Yinzhu.

After doing this, Bo Saixi moved and came to the top of a nearby mountain. At this time, Tang Chen appeared behind him and hugged Bo Saixi's delicate body.

"Oh, brother Chen, don't make trouble."

"Hehe, what is their assessment?" Tang Chen chuckled, looking at the boulder on the side, waving the Clear Sky Hammer quickly in his hand, and soon two exquisite stone seats appeared in front of the two of them.

"The dog and the girl formed by the evil power were trained by the tide. Lin Feng doesn't know if he offended the Poseidon somewhere. His test is to use his soul power to grind Chen Yinzhu into needles." Bo Sai Xi said.

"Hey, the assessment will take a year, and I have to supervise them here, but it's boring, Brother Chen."

"It's okay. I'm here to accompany you, right?" Tang Chen held Bo Saixi's blue hair and said softly.

"However, I estimate that Lin Feng's assessment will take less than a year." Tang Chen said as he lay on the stone chair, thinking that he would have to ask Lin Feng for a sofa after a while.

"Oh? Are you so optimistic about him?" Bo Saixi asked, recalling that Lin Feng had passed the previous two tests.

"But there are a lot of secrets about Lin Feng. I couldn't even see through the gray light on his body in the first level, and I've never heard of the thing that can emit electricity in the second level."

"Ahem, Xixi, everyone has their own secret." Tang Chen said.

"I believe that this guy Lin Feng will definitely surprise you at the third level."

"Let's wait and see."

"I don't believe it. Those sunken silver pillars in the deep sea were formed by thousands of years of waves washing and settling. Without the use of soul power, even I dare not say that it can be easily ground into a needle." Bo Saixi shook his head, as if he was not convinced. Not optimistic about Lin Feng.

"Hey, Xixi, let's make a bet. If Lin Feng completes the challenge within ten days, I will give you..." Tang Chen quietly whispered into Bo Saixi's ear.

When Bo Saixi heard this, her face instantly turned red. She patted Tang Chen's thigh and said shyly, "You old and crooked man, okay, if Lin Feng completes the challenge within ten days, I will agree to the unreasonable request."

This made Tang Chen so happy that he shouted loudly to Lin Feng below.

"Boy Lin Feng, try to complete the assessment within ten days, for my happiness!"

Lin Feng, who was on the Chen Yin Zhu, looked at the hard gray Chen Yin Zhu under his feet with interest, and thought of an interesting subject in his previous life - chemistry.

Gray silver, should it be oxidized silver?No, silver oxide is a powder, not so dense. It must be a silver compound anyway.

In his previous life, Lin Feng was pretty good at chemistry. Seawater adhering to the surface of the silver pillar would form a galvanic cell and accelerate the oxidation of the silver. Of course, it does not rule out the possibility of reacting with other substances in the seawater.

According to Lin Feng's speculation, there should be a hard compound on the surface of this sunken silver pillar, and the middle of it must be relatively high-purity silver.

Then it's much simpler, just remove the compounds on the surface.

As an inactive metal, silver can only be oxidized. To change back, it only needs to undergo a reduction reaction.

Thinking of this, Lin Feng took out a high school chemistry book from the Qiankun Ring and started rummaging through it.

Found it, the redox reaction of silver!

Methods that require a reducing agent should be eliminated first, because Lin Feng does not have one, so the only way to do it is by electrolysis.

Just do it, Lin Feng took out various things.

High voltage generator, ready!

Silver Pillar, ready!
Connect the silver column and the sunken silver column through wires, start the high-voltage generator, and put on insulating clothes first. I almost forgot that silver is conductive.A strong electric current acts on the immersed silver column, and soon a large number of bubbles begin to appear on its surface.

Success!Started to react.

Lin Feng was overjoyed when he saw the phenomenon in front of him.

Sure enough, if I learn mathematics, physics and chemistry well, I will not be afraid of traveling all over the world. The teacher will not deceive me.

The next step is to wait. After all, such a large immersed silver pillar should have a large number of compound layers on its surface.

"Woof woof, ouch!" A wave of waves hit Xiaobai, and Xiaobai on the side shouted loudly.

"Why do I feel so numb all over my body?"

Lin Feng couldn't help covering his mouth and snickering. Fortunately, he was far away, otherwise it would not be numbness, but a dog jumping over the wall.

On the contrary, Huanhu, as a soul, not only had no feeling at all, but was also speechless.

"Auntie, I don't have a physical body. What's the use of being tied here? Who in the family knows."

Bo Saixi, who was at the top of the mountain, looked at the three people below who were undergoing the assessment with a strange look on his face, and said to Tang Chen, who was sitting leisurely reading a book.

"Brother Chen, why do I feel that none of these three are normal people?"

"Ahem, this assessment really has no effect." Tang Chen said.

"That dog named Xiaobai is extremely strong. I feel that it can withstand the attacks of ordinary titled Douluo, and it will be easy to swim in the sea."

"And Huanhu is a soul and has no entity at all."

"The only one who is physically weaker, Lin Feng, is actually ground into a needle in his assessment."

Bo Saixi was speechless.

……

the next day.

After resting for a night, Lin Feng and others returned to the assessment location.

Xiaobai and Huanlong looked helpless and were tied to the Chen Yinzhu again. This time, Huanlong behaved and took a novel to pass the time.

Lin Feng came to his Chen Yin Zhu. After the generator worked for a day and night, the color of the originally gray Chen Yin Zhu had become a bit brighter.

Seven days later, Lin Feng saw that the entire Shen Yinzhu seemed to have successfully lost weight and had become thinner, and its surface had turned a bright silvery white. Lin Feng realized that all the compounds on Shen Yinzhu's surface had been restored.

Putting away the generator and Lin Feng's own gray silver pillar, Lin Feng took out a file and started sharpening it against the silver pillar in the sea.

Silver is inherently soft and extremely easy to polish.

In less than a day, Lin Feng appeared in front of Bo Saixi holding a silver needle.

"How did you do this?" Bo Saixi had seen Lin Feng's movements in the past few days. She really couldn't understand why a good heavy silver pillar turned into an ordinary silver pillar.

Lin Feng smiled and said nothing. After all, science in the past life was not something that could be achieved overnight. If given the opportunity, Lin Feng would not mind spreading science in Douluo Continent.

As Bo Saixi announced that Lin Feng had passed the examination, the familiar majestic voice sounded for the third time in the depths of Lin Feng's mind.

"The third test, Tidal Body Refining, completed, reward: Poseidon affinity increased by 15%."
