The ultimate transmission fear beast stands on the Douluo Continent.

Chapter 455: Growth of External Soul Bone

"Remnants?"

After briefly escaping from the busy work, Gu You's brain automatically searched for relevant fields and finally found that there was no such person. He asked in confusion: "Who is it?"

"I don't know."

Meng Yiran shook her head: "She said you will know, and told us to just convey it to you word for word. Because she looked very confident, Butler Feng is now making tea for them in the reception room."

"Understand? You understand nothing."

Gu You said unhappily, "I'm so busy that I don't have time to drink tea and chat with these guys who come from unknown places. They don't even know you. They may be small characters sent by the nobles to build relationships. Don't pay any attention to them. Let them get lost as far as possible."

"No, it's not the right time to break up with the nobles yet."

Realizing that stability needed to be maintained before Xue Qinghe officially took over, Gu You added: "When telling them to get out, be more tactful and say that I'm in seclusion practicing some extremely difficult self-created soul skills, and I'm going to give the Spirit Hall team a head start in the All-Continent Soul Master Competition."

"I just don't believe they are so bold as to not take the reputation of the empire seriously."

After that, Gu You pointed to the door, indicating that Meng Yiran could leave, and said to Lanta, who was writing furiously, "Ata, stop over there for a moment and hand me the book "A Brief History of the Development of Attack-type Soul Masters" in the middle of the third row of the bookshelf on the right."

"Okay, big brother."

Ranta stopped writing, stood up and walked to the bookshelf, stood on tiptoe, and took down the "Brief History of the Development of Attack-Type Soul Masters" which had a history of 700 years.

I have to mention that fortunately there are not many people in Douluo Continent who love reading. Otherwise, if you want to take a look at the authentic old books, you have to spend at least six figures.

Meng Yiran thought about it and said, "Okay, I'll go talk to them."

If the "survivors" are really related to the nobles as Gu You guessed, then as the spokesperson of the Tiandou Empire, she has reason to intervene.

After all, she voluntarily chose to take over the affairs of the Tiandou Empire, and also got the abridged version of the "Spartacus" plan from Gu You. No matter how you look at it, there is no turning back.

Regardless of whether the target is Gu You or "Gu You", the behavior of bypassing Xue Qinghe and contacting him privately obviously needs to be carefully guarded against.

"Oh, right."

Just as he was about to leave, Meng Yiran suddenly remembered something: "Xiao You, besides us, who else knows that [Huo Dou] was created by Xiao San?"

"[Huo Dou]?"

What's going on? Someone was slashed in the street and the scars were found to be consistent with those of a [Huo Dou]. Are you responsible for tracking down the murderer?

Due to recent overwork, Gu You's tired brain has begun to automatically serialize the story of "Detective Meng Yiran" in order to relieve stress.

You can refer to the plot of Detective ○ South theatrical version. At the beginning, Xiao Hei sneaks away the evil spirit from Ning Rongrong's boudoir under the cover of night, and then kills a retired finance minister with a sword. There are some unnecessary reasoning links in the middle, and then there is a long chase scene. Then the Tiandou Palace or the Tiandou City Fighting Spirit Arena collapses in the explosion, and then you can start making dumplings.

I feel the script is okay. At least there won't be some underage unicorn with double A strength and speed who kills dozens of people with his bare hands.

Shaking the strange idea out of his head, Gu You opened the book and answered absentmindedly: "There are quite a lot of people, Grandpa, Brother Tao, Grandpa Ma Xiunuo, Sister Nightingale, Xue Qinghe, Dugu Bo, Ma Hongjun, She Long, and Cixue. They all know that Xiao San can forge soul guides."

"If we count those who have the ability to guess, the three teaching committee members of the academy and Teacher Qin Ming, Ning Fengzhi of the Seven Treasures Glazed Tile Sect, and even some smart people of the Blue Lightning Tyrant Sect may have guessed it."

"Oh, by the way, the fighting spirit arena is also possible."

Meng Yiran seemed a little surprised: "Why?"

"Because the Fighting Spirit Arena building itself is an oversized soul guide device."

After writing down the useful parts of the book, Gu You said calmly, "You and I are both soul masters, and we should have a basic understanding of the damage caused by soul skills. The fighting arena, which bears at least dozens of soul masters fighting every day, shows an intensity that is obviously inconsistent with the level. Why are you surprised? Didn't I mention it?"

"."

Meng Yiran had a stern face and closed the notebook that Gu You had written halfway. "You, go to the laboratory and call Xiao San now. Show up in the reception room in five minutes."

"?"

"Their target is not you, but the mistress who forged the [Huo Dou]."

Meng Yiran still asserts this.

A minute later, Gu You, who handed over the follow-up work to Lanta, raised his hand and knocked on the door of the temporarily renovated laboratory.

"Please come in."

He pushed open the door, put on his protective clothing expertly, walked to one side of the workbench and stood still, then said to Tang San on the other side: "Any new discoveries?"

"Unfortunately, just like yesterday, the day before yesterday, and the day before yesterday, there has been no substantial progress."

Without even raising his head, Tang San raised three fingers on his left hand, motioning Xiao Wu to fetch the experimental reports of the past three days.

Given Xiao Wu's identity as a hundred thousand year old soul beast, she has recently begun to participate in Tang San's research on external soul bones as an assistant.

Although she did not provide effective help for the research, at least her existence saved Tang San from wasting time filling out experimental data reports.

By the way, you can change your pocket money into labor fees and help with cleaning.

Tang San said quietly: "The Cinder Blade Dragon Tail Vertebrae is an external soul bone that is rarer than any other soul bone, and has a unique growth potential among soul bones."

"From a purely theoretical perspective, its structure must be vastly different from that of ordinary spirit bones."

"But unfortunately, whether it is on a physical or spiritual level, I can't find any difference between it and the Lightning Wood Soul Bone or the artificial soul bone. It's like the external soul bone is just a soul bone with a special shape, and it doesn't have the growth potential recorded in the records."

"First of all, it's called the Cinder Blade Dragon Pelvis."

Gu You said: "Secondly, in every book that records external soul bones, it is noted without exception that it has a different growth potential than other soul bones. I don't think the people who wrote the book would be so idle as to make fun of us."

He took the experimental report of the past three days handed over by Xiao Wu and raised his eyebrows: "Tsk, tsk, tsk, tsk, smoking, fire roasting, freezing, long-distance soul detection, mental power observation, Purple Demon Eye perspective, there are quite a lot of experimental variables. Huh? You also did a venom immersion test?"

"Yeah." Tang San nodded calmly: "This morning, I used a full ten liters of ten thousand year old mandrake snake venom, directly emptying the old poison's stock."

Gu You's eyes widened: "Shi Sheng?! He's not going to fight you to death?"

"of course not."

Without giving Gu You a chance to have fun, Tang San said, "I told Old Poison directly that the growth of the external spirit bone is the most suitable spirit bone for storing the Green Scale Snake Venom, nothing else. Using spirit beast venom to test is to find the key to mass-producing growth spirit bones."

After saying that, Tang San picked up the glass bottle at hand and poured it all onto the soul bone.

'Did you get an internal heat from the barbecue yesterday?'

Gu You scratched his head in confusion, not understanding why Tang San had such a sour face.

It probably has nothing to do with the failure of the experiment.

At the Yin-Yang Eye of Ice and Fire, the two dared to challenge to directly use soul beast materials to directly create poisonous attribute artificial soul bones without poisonous attribute soul guide array. Now that there is a real object for reference, Xiao San can't have a mental breakdown.

After thinking about it for a while but couldn't figure it out, Gu You put the matter behind him and continued reading the experimental records.

Unexpectedly, he found something very interesting on the last page of the report.

Six types of soul bones and external soul bones: three hypotheses behind the unique growth potential

Oh my god, Xiaosan has also started writing a paper! ?

Unable to control the upward curve of his lips, Gu You was just about to speak when he found Xiao Wu walking towards him quietly, secretly winking at him.

The unreliable brother and sister were in spiritual communication at this moment. Gu You hid the half-finished paper handed to him by Xiao Wu behind him faster than he hid his cell phone when he was in school.

While Tang San was concentrating on observing the changes in his spirit bones, Gu You, full of anticipation, lowered his head and began to read his first paper.

"With the full deployment of artificial soul bone technology, the stagnant soul master world will usher in a huge change. Countless new generations of soul masters will rise up, and many old masters will give up the center of the stage and retreat silently to the second line.

At first, people will ignore the age, material, and skills of soul bones, and enthusiastically pursue the soul bones themselves in order to gain a place in the new era. But after a short period of enthusiasm, soul masters will eventually regain their composure, and their demand for soul bones will gradually transition from "just having soul bones" to "as long as the soul bones suit their own situation."

"Suitable for one's own situation" does not necessarily refer to the soul bone skills that come with the soul bone and the soul master's combat system, it may also refer to the soul bone itself, which happens to be the part that the soul master needs most.

Especially for soul masters who specialize in the field of combat, they need to be more cautious in choosing soul bones.

For example: A soul master with a hammer spirit, without considering soul bone skills, will naturally prefer arm bones that increase arm strength over leg bones that increase speed.

However, the randomness of artificial soul bone components makes the benefits of artificial soul bones unpredictable. The high material cost may result in a total loss.

After all, no one wants to spend a lot of money to make an artificial soul bone, but it turns out not to be in their dominant hand.

So, how can we reduce this risk?
The answer to the question may be hidden in the external soul bone.

As we all know, external soul bones have two major characteristics that are independent of ordinary soul bones.

The first is the form. The external soul bone will perfectly inherit the characteristics of the soul beast, and then independently manifest itself on the soul master.

The most famous one is the Dark Gold Terror Claw Bear Metacarpal Bone. The dark gold sharp blades extending from the five fingers are so powerful that they can completely rival the genuine Dark Gold Terror Claw.

The second is growth. The power of the external soul bone will grow with the improvement of the soul master's cultivation. The growth limit is unknown. Legend has it that it can compete with a hundred thousand year soul bone.

The record for the external soul bone with the largest known growth rate comes from the Hundred-Year-Old Frog Hyoid Bone 250 years ago. It is so powerful that it can even compete with the 80,000-year-old Spinosaurus trunk bone.

With today's soul guide technology, perhaps two hundred years later, we still won't be able to crack the random form problem of artificial soul bones, let alone external soul bones of various shapes.

However, since every external soul bone has growth potential, there is a chance to produce research results without a large number of samples.

If the growth potential of the external soul bones can be successfully transplanted to ordinary artificial soul bones, the soul bones made of low-quality materials will be blessed by the soul master's talent, and the cost risk will be eliminated. "

'interesting. '

Gu You held up his chin and pondered, following Tang San's line of thought, and began to ponder the feasibility of artificial external spirit bones.

Just like common carbon, it will turn into precious diamond under high temperature and high pressure environment.

Ordinary soul bones and external soul bones are both products condensed after the death of soul beasts. In theory, the growth potential of external soul bones does have the possibility of being transplanted to ordinary soul bones.

But the problem is that the external soul bones that can grow seem to have always been a plug-in exclusive to the protagonist in Douluo Continent.

From the Peerless Tang Sect to the Ultimate Douluo, a full 20,000 years have passed, and countless experts who have studied artificial soul bones have not been able to solve the problem. Gu You is really not very confident.

The problem can be solved, but it will take at least several decades, plus a large number of consumable external soul bone samples.

Therefore, even though Notting City had a lot of time for research, Gu You never focused his energy on external soul bones.

After all, if he didn't absorb the human-faced demon spider's soul ring, how could he get an external soul bone as a research sample in Douyi?

Now that he had the sample, dozens of guesses about the growth potential of external soul bones flashed through his mind quickly. Gu You came back to his senses and continued reading.

Hypothesis 1: Nature of the material
Considering that when the external soul bone is released, its shape is usually manifested as a stronger part of the body soul beast (the legs of a spider, the claws of a bear, the eyeball of an eye, etc.).

Perhaps in the process of the external soul bone condensing and forming, just like artificial soul bones require soul beast materials, it absorbed certain characteristics of the soul beast parts.

Hypothesis 2: Innate lack of airtightness

According to records, the growth potential of external soul bones is reflected in the fact that they will increase with the growth of the soul master's strength.

Considering that there has never been a precedent in history of absorbing external soul bones without being on the spot, it is speculated that the external soul bones are not airtight enough and may have an interface connected to the outside world, which will then slowly absorb the soul master's soul power to complete the evolution. "

"."

Seeing this, Gu You couldn't help but feel a chill.

Crazy scientist Tang San? Why would I have such a dream?

Fortunately, the attached soul bone is leak-proof, otherwise the venom of the ten thousand year old mandrake snake would definitely turn this tempting treasure into the most attractive chronic poison.

Without looking at the more detailed experimental records later, Gu You added a third conjecture after the second conjecture.

"Hypothesis 3: Soul power deteriorates

As a soul power creation, the growth process of external soul bones must involve soul power.

Perhaps during the process of the external soul bone condensing, the nature of the soul power on the surface changed for some reason. While retaining the airtightness, the soul power flowing through only enters but does not exit (more near and less out), thus obtaining a unique growth potential. "

Just after handing the simply revised paper back to Xiao Wu, Gu You heard Tang San smacking his lips in dissatisfaction: "Tsk, it really doesn't work."

He observed for about three minutes, but did not see the expected reaction. A colorless solution of unknown composition slowly flowed down along the outline of the bone, landing on the workbench with a crisp "tick-tick" sound.

Using the Crane Controlling Dragon Capturing Technique to retrieve the solution, Tang San said without even turning his head: "The strong acid solution has no reaction, the experiment failed."

"Xiao Wu, go to the freezer and get the Blue Silver Grass Extract No. 78 and the Blue Silver Emperor Extract No. 14. Then give me the cleaned Lightning Wood Soul Bone and the artificial soul bone. Next, we will do a cross-control experiment."

"Okay, third brother."

Xiao Wu was startled and immediately went to prepare the experimental materials.

"Okay, Xiaowu, go and have a rest first."

Taking this opportunity, Gu You quickly said, "Xiao San, follow me. Someone wants to see the forger of [Huo Dou]."
