"Are you sure you're not kidding me?"

Prince Su looked at the transparent coffin-like thing in front of him with a look of suspicion.

"Are you sick, I'm spending so many spirit stones to tease you?"

Prince Su tilted his head to think about Chen Yuan's stingy temperament, and recalled the past when he was chased and killed by Senior Sister Li all over the mountains in order to earn seventy spirit stones, and finally nodded in agreement and said, "This is also ......."

Chen Yuan's face darkened, ignoring him.

After Chen Yuan called Prince Su to the secret room before, he took out the harvest in Yun Mengze, and successfully connected the energy system of the life support warehouse to the Tianyuan Formation, and then he only needed to put spirit stones into the formation as an energy source.

Because he knew that this kind of genetic modification required a lot of energy, Chen Yuan deliberately took a detour to the second treasure before returning to the mountain, and took out all the dividends given to him by the fat man.

These low-grade spirit stones are no longer of much use to Chen Yuan, they can neither be used to improve his cultivation, nor can they be used to acquire those rare materials, but they can be used to charge the life support warehouse and make the best use of them - anyway, the Tianyuan Formation will not be picky about the grade of the spirit stones.

However, what Chen Yuan didn't expect was that the energy required for this genetic modification was far beyond his expectations.

At this moment, he had already invested a full twenty thousand spirit stones into the Tianyuan Formation - although they were all low-grade, but the life support warehouse in front of him, except for the green indicator light that represented the charging, there was no more reaction.

Puzzledly, he called up the system menu to check, Chen Yuan screamed "ah", and almost fainted in front of him: the progress bar representing energy reserves was almost untouched, and then looking at the number display, the big 1% was simply shocking.

Twenty thousand spirit stones are only filled with one percent of the required energy, which means that if you want to complete the transformation, you need as many as two million spirit stones!

This number sounds terrifying, but when you think about it, it is not surprising, the transformation itself may not require much energy, but it is a huge consumption to solidify this ability to absorb aura in the body.

Compared to the nearly one million pores on the whole body, the number of two million is not very exaggerated.

However, understanding is understanding, and the heart should drip blood or blood.

At this moment, Chen Yuan said in a broken voice: "This transaction is really a big loss, this is two million spirit stones, you must know that you were only a Jindan cultivator before you were injured, and two million spirit stones are enough to hire a hundred Jindan monks to listen to me......"

"No, I have to find a way to recover some losses," Chen Yuan was spinning around like a trapped beast, and suddenly, his eyes lit up and stopped, and he said to himself: "By the way, I can let Su Laosan's younger brother who became the emperor pay for it, if he dares not to reimburse him, I will put Su Laosan back and grab the throne with him!"

Prince Su couldn't cry or laugh when he listened, what do you mean by putting yourself back, do you Chen Yuan think this is closing the door and letting the dog go?

However, Prince Su looked at the machine that was devouring the spirit stone, and his eyes were also full of expectation: can this thing really heal his injuries and allow him to embark on the path of cultivation again?

At this time, Chen Yuan threw the storage ring full of spirit stones to Su Xiannan, and sighed: "It will take a day and a night to see that this progress is fully charged, you are staring here, I will go back first, hey, out of sight and out of mind......"

After leaving the secret room, Chen Yuan's eyes were clear, and the look of chagrin on his face before was not visible at all.

In fact, that gesture just now was just laughter and sparring among friends, in order to heal his brother's injury, Chen Yuan could force his way into Yunmengze several times regardless of the danger, how could he care about this mere two million spirit stones?

On the way back, Chen Yuan had another thing in mind: when he left before, Wang Zizai came to find him and left a message, telling him a shocking news.

Feng Xiaoxiao is the so-called "Blood Demon Ancestor"!

This news was unbelievable when he first heard it, but thinking of some strange things before, Chen Yuan had to accept this fact!

In fact, there have been clues to be found for a long time: when Fengyun City first met, Feng Xiaoxiao was just a late Jindan cultivator, and when Fengjian City met again the following year, he was promoted to Yuanying Monk, and after two more years, when the battle of Ningcheng was over, Feng Xiaoxiao secretly had a distraction cultivation.

No matter how talented Feng Xiaoxiao is, it is impossible for him to make such a fast progress, which is simply faster than devouring spirit stones to improve his cultivation!

Looking back now, the most likely thing is that there was something wrong with the discovery of the traces of the Blood Demon Ancestor in Beibi Mountain, but this Blood Demon Ancestor was at the end of his rope under the joint pursuit of the Righteous Dao Sect, and then he happened to be met by Feng Xiaoxiao, who went to collect spiritual grass, and picked up a corpse.

After that, perhaps because he was bewitched, or perhaps because of greed in his heart, Feng Xiaoxiao did not destroy the inheritance of the Blood Demon Ancestor, but chose to cultivate secretly.

Then, there was the bloody case of the 3,749 lives of the northern tribe.

I'm afraid that at that time, Feng Xiaoxiao had already used this evil method to be promoted to Yuanying.

It's just that Feng Xiaoxiao was scheming, deliberately covered up his cultivation with serious injuries, and cut off one of his arms to clear his suspicion.

After that, there was the bloody murder at Kazama Castle Palace.

Chen Yuan closed his eyes and recalled the scene.

Because he was awakened by the evil omen in his heart, he got up to find Feng Xiaoxiao, but he was blocked by him under the pretext of going to the toilet.

Thinking about it now, at that time, he should still be wantonly slaughtering and absorbing essence blood in the palace, and even the voice in the room was just an illusion created through the sound transmission formation.

After that, he took a bath and applied incense powder, probably just to cover up the thick smell of blood on his body!

From the time he went to look for him, the sound of bathing water really sounded in the room, Chen Yuan silently recalled in his heart and gave a number: Four minutes and seventeen seconds, coincidentally, this is exactly the time it takes for a monk who is in the early stage of distraction to rush back to the inn from the palace with all his might!

Although these are just his own speculations, Chen Yuan believes that this speculation is definitely not far from the truth.

It's just that there are still two doubts in this, and Chen Yuan hasn't figured it out: one is Feng Xiaoxiao's purpose for doing this.

It stands to reason that when Feng Xiaoxiao decided to learn demonic skills, he was only a small Qi cultivator, and it couldn't be the pressure he brought him, so what made him abandon his identity as the first elder disciple of the Holy Land, and was willing to risk ruining his reputation?

The second point that made Chen Yuan puzzled was: At the time of the palace bloody case, Feng Xiaoxiao should have just passed the promotion through magic skills, and his breath must be unstable, plus he usually gets along with Feng Xiaoxiao for a long time, so did the Great Elder Mo Cangxing find the abnormality in his apprentice?

If not, Mo Cangxing would be too negligent, and if he knew about it but chose to ignore it, he couldn't help but think about it carefully.

These analyses and speculations, Chen Yuan is not ready to report but intends to bury them in his heart for the time being, the Law Enforcement Hall has a deep foundation, and this matter involves the hall master and the chief disciple, if there is no real evidence, the two of them will definitely not be able to be defeated by a few guesses and inferences from Chen Yuan.

Rashly publicizing it can only startle the snake, and it will also put oneself in a dangerous situation.

Leaving this month is not all troubles.

There is good news: Lord Gou Yu has finally returned after leaving Xiao for half a year, and it is said that it has brought Chen Yuan a lot of benefits.
