Chen Ning originally wanted to try his luck with the butcher and see if the butcher could guide him in two moves, but he didn't expect that the butcher was not at home, but he met Fang Zheng by chance, and learned from Fang Zheng and the bloody tyrant about the magic of the zombie brain nucleus, which made him very happy.

After leaving contact information with Fang Zheng, Chen Ning immediately returned to the small mansion he had purchased with the Bull Demon King in Vermilion Bird City.

Chen Ning told the Bull Demon King not to disturb him, and then he went back to the room, closed the door, and took out all the zombie brain cores, a total of seven pieces. One is a ninth-level Demon Apostle Brain Core, two are Frieza Brain Cores, and four are Predator Brain Cores.

Chen Ning originally planned to hand over these brain nuclei, but because he reported to Qin Que and had a conflict with Xiao Zhuo, he forgot about it. In addition, he himself couldn't explain why he was able to kill the ninth-level demon apostle zombies, so he never handed over these zombie brain cores in the end.

Chen Ning looked at the seven zombie brain cores on the table, and finally decided to try a small one first.

So, he grabbed a fourth-level brain nucleus with his left hand and used the Devouring Technique.

A magical scene appeared, the zombie brain core melted like an ice cube, and was sucked into Chen Ning's spiritual world by the devouring formula.

Moreover, the fourth-level brain nucleus, which was originally only the size of a walnut, fell into Chen Ning's spiritual world, and turned into a full dozen cubic meters of crystal clear liquid, Chen Ning was shocked, a small piece of fourth-level brain nucleus could be turned into a dozen cubic meters of liquid?

Chen Ning found that there were no other adverse reactions except for more than a dozen cubic meters of crystal clear liquid in the riverbed in the spiritual world.

So, he immediately picked up the second zombie brain core, this time trying the sixth-level Frieza brain core.

After the brain nucleus was also devoured with the phagocytosis technique, the sixth-level brain nucleus turned into more liquid, with more than thirty cubic meters of water.

Chen Ning vaguely understood that the brain core of a first-level zombie could be transformed into about 1 cubic meter of energy water, the brain core of a second-level zombie should be able to turn into 4 cubic meters of energy water, the brain core of a sixth-level zombie could be transformed into 36 cubic meters of energy water, and as for the ninth-level zombie, it is estimated that it could be transformed into 81 cubic meters of energy water.

However, the more advanced the zombie brain core, the purer the energy water will be, and it is estimated that the effect will be greater.

In order to verify his conjecture, Chen Ning used the devouring technique to devour the ninth-level zombie brain core, and sure enough, it turned into about 80 cubic meters of energy water, proving that Chen Ning's guess was correct!

Chen Ning immediately devoured the rest of the sixth-level brain nuclei and fourth-level brain nuclei, and finally in his spiritual world, more than 200 cubic meters of ability water had been added to the spiritual riverbed, which made the water level of his spiritual riverbed increase by a cut.

Coupled with the martial water he had cultivated and stored before, it was almost full.

Of course, if you have to rely on the cultivation of the Tiger Ben to fill the remaining water level, it is estimated that there will be a month or two of cultivation.

As for the martial arts exam, there are still ten days to start, and the time is not enough.

Since there is never enough time to cultivate the tiger body, then we have to think of a way from somewhere else, blood is a good substitute, but with the increase of Chen Ning's strength level, the blood of ordinary pig blood and cow blood of these animals has little effect, and using the blood of these animals instead of the water of force to impact the martial veins may eventually lead to the failure of lighting up the martial vein nodes, and the previous efforts will be wasted.

Human blood is the best guarantee, but although Chen Ning has become a demigod, he still has a human heart in his body, so he can't do the practice of killing humans to obtain blood.

There was no way, Chen Ning could only go to Liu Ruyan and ask the other party to secretly help him drumble up some zombie brain cores.

It is illegal to buy and sell zombie brain cores, but there is a market for buyers, and many imperial soldiers will pick up and secretly go to the black market to buy zombie brain cores in order to obtain meritorious service, and then hand them over to the empire, falsely report military merits, and get promoted. In particular, some soldiers who were born as disciples like to do this, because their families are not short of money.

Therefore, the big commercial houses also secretly provide zombie brain core services, but they are only sold to new customers, and the price is very expensive. After all, it is illegal to buy and sell zombie brain cores, and it is not easy to get zombie brain cores.

At that time, the bosses of the big commercial houses were not so stupid, they would send people to take risks to hunt zombies, and the zombie brain cores in their hands were basically purchased from bounty hunters.

Liu Ruyan heard that Chen Ning needed a zombie brain core, and he didn't ask why, so he personally sent a batch of zombie brain cores to the door, most of which were fifth-level Cerberus zombie brain cores, and some were low-level zombie brain cores, a total of twenty.

Liu Ruyan said to Chen Ning: "Now our firm only has this bit of goods, and these fifth-level brain cores are still bought from the Colosseum." However, the Colosseum is gone, because with the Grand Governor leading the army to retreat to Vermilion Bird City, the former real power figures in Vermilion Bird City have now become dozens of leaders, and they have no part to speak. Moreover, Vermilion Bird City is now very strict with the transportation of zombies and brain cores, and the Colosseum has canceled the performance of challenging Cerberus, and we can't get a channel for the brain core in a short time. ”

Chen Ning looked at the twenty brain nuclei and said with a smile: "These are enough, Miss Liu, how much are these." ”

Liu Ruyan said with a smile: "Did I say that I wanted to collect money, why are you in a hurry to give money?"

"I'm afraid I owe you too much favor and can't afford to pay it back. ”

"Don't be afraid, then give me back your whole person. After Liu Ruyan finished speaking, she probably felt that her words were a bit ambiguous, and the meaning of teasing was too obvious, so she immediately added: "Hehe, our business bank is to arrest the guys who owe money to work." ”

Chen Ning was really a little afraid that he couldn't afford to pay it back, so he insisted that Liu Ruyan give a price, and in the end, Liu Ruyan symbolically collected Chen Ning thirty gold coins. On the black market, this is already a very low price.

After Liu Ruyan left, Chen Ning used the devouring technique again to devour all twenty brain cores.

At this moment, the spiritual riverbed in his spiritual world has been filled with river water, and he can officially try to light up the sixth node of the black and white martial vein.

"Tiger Benjue, turn!"

With a buzz, the terrifying head suspended above the Youyou River suddenly began to spin with Chen Ning's voice, and it also emitted a sharp and strange whistling sound.

At the same time, the spiritual world began to change color, and the originally calm river also began to rise in the wind and waves, and the waves pushed and pushed again, and became more violent than the other, and began to impact and lap the riverbank.

In the end, the waves became more and more fierce under the overlapping and propulsion, and finally turned into a tsunami, rushing up to the river bank, and frantically rushing towards the towering black and white martial arts twin towers on both sides of the river bank.

The whirling heads in the sky let out a ghostly howl, as if to summon the spirits of the river inside.

Under the gloomy sky of the stormy clouds, in the tsunami frenzy, there were many vague shadows, the most eye-catching of which was a tall and winged demon, which took the lead in the fierce direction of the black martial pulse, followed by the shadows of Frieza and Cerberus, predators and other zombies, like a team of ghost warriors, faintly appeared in the wave, and hit the sixth node of the black and white martial vein with the wave......

I don't know if it's because of the addition of a lot of zombie brain cores, this time the impact of the black and white martial veins and the lighting of the sixth node turned out to be very easy, and it didn't take long to break through the sixth node of the black and white martial veins and light up.

Even, the remaining strength of the wave has not disappeared, and it can continue to hit the seventh node, but unfortunately, it was not able to break through the seventh node by the way.

Chen Ning opened his eyes, happy that he had successfully stepped into the strength of the double sixth-level general, but also a little disappointed, because he just felt that if the strength of the wave was a little stronger, it would be possible to break through the seventh martial vein node, but it was a pity.

However, now the strength of the double sixth-level generals, even if they meet the seventh-level generals, they have the power to fight, which makes Chen Ning finally have enough confidence in the title of martial champion!
