Chu Du had already stared at the aperture in front of him with twelve points of energy, only to see that the inscription in the aperture changed violently again, and a flash of light shot out of it and disappeared into Chu Du's eyebrows.

In an instant, Chu Du felt that a giant blade had entered his sea of consciousness, cutting his mind to pieces.

"Quickly activate the Concentration Bead, and then use all your spiritual power to control this external spiritual power, and finally run the Extreme Dao Star Sutra. Yin Hao on the side saw Chu Du's face showing pain, and hurriedly shouted, and then thought that Chu Du was in the system, even if his head was broken, it would be fine, why were he so worried!

There was no need for Yin Hao to remind him, the Concentration Bead on Chu Du's chest had already released a sparkling glow, and Chu Du's own spiritual power was increased, and then Chu Du controlled all his spiritual power to wrap up the foreign spiritual power that was raging in his mind, and at the same time tried his best to stabilize his mind and run the Extreme Dao Star Sutra, only to see a vortex that was much larger than when he had cultivated the Extreme Dao Star Sutra directly above Chu Du's head.

With the appearance of this whirlpool, Chu Du's mind also became relaxed, at the same time, Chu Du also felt that he had established a connection with many stars in the void, Chu Du carefully observed, and found that there were 33 stars that had established contact this time, without the help of the big array, Chu Du's limit was only 15, and now it had increased by 18.

Chu Du didn't dare to pull down so many stars at the same time, first, he was afraid that the movement caused would be bigger than when Shi Zhihan was cultivating, and second, Chu Du's current purpose was not to self-detonate his body refining and impact the mysteries, what Chu Du wanted to do most now was to use the Taiji ball in his body to fuse the power of the stars.

If the force of a traction is too much, it will be a big loss if you accidentally lose the Tai Chi ball, so Chu Du's little bit of experiment.

The power of the 15 stars that Chu Du pulled at a time last time was not the opponent of the Taiji Ball at all, so this time Chu Du took the initiative to cut off the connection with 17 of the 33 stars, and only pulled the power of 16 stars into the dantian, of course, this power of the stars will not cause much movement.

However, it is obvious that the power of the stars that was pulled down was also not the opponent of the Taiji Ball, and he was quickly driven out of the dantian, Chu Du did not have any disappointed expression on his face, and got up and prepared to take out the demon core two, anyway, this will not need to pull the power of 33 stars, and it will not need such a strong spiritual power, and it can save some use.

However, Chu Du thought about it, since he can self-detonate and cultivate his physical body, and now he introduces a large amount of foreign spiritual power to fight against his own spiritual power, will his spiritual power increase very quickly after a long period of training? Anyway, it's okay to be broken in the head, Chu Du plans to buy more demon cores and fill the aperture on the Nine Yuan Regent Formation Array, and then the self-detonating head cultivation can begin.

Thinking of this, Chu Du didn't take down the demon core, and began to stimulate the big array again, this time Chu Du didn't use the Concentration Bead, and as a result, under the impact of this foreign spiritual force, Chu Du insisted on a few breaths and his head exploded, but it didn't explode, but he still bled to death with seven orifices.

"Have you started the perverted cultivation method again?"

Yin Hao on the side saw that Chu Du's Concentration Bead did not react, and he knew what Chu Du had in mind, but when he said that, Yin Hao also felt that Chu Du's method was absolutely effective.

After the resurrection, Chu Du got up from the ground and said to Yin Hao with a smile: "Useful methods are all good methods, no matter if he is perverted and unchanging, but I just experienced it, and I will practice this later, and I will fuse the power of the stars first." ”

Next, Chu Du added one more star power every time, until the power of 28 stars entered the dantian, and he still couldn't help the Taiji Ball, but the time to fight against the Taiji Ball has been a lot longer.

When Chu Du was about to increase the power of the stars, he found that the six Tiger Demon Cores had been scrapped, and Chu Du had no choice but to stop the experiment.

"The demon core of 300 medium-grade spirit stones has only been used 14 times, this kind of cultivation is a bit expensive!" Chu Du sighed as he looked at the demon core that had been shattered into powder.

"Of course, whether it is refining the body or refining the qi, the more you go to the back, the resources spent are astronomical, your little spirit stone should buy the cultivation materials first, and I will count the five element materials first." Yin Hao said on the side, to be honest, even if Chu Du has the help of the accompanying treasure, Shou Yuan is not a problem, Yin Hao does not want Chu Du to waste time on the Five Absolute Great Destruction Sword, Yin Hao thinks that Chu Du's double cultivation of the Dharma Body will be enough to crisscross all directions in the end.

However, of course Chu Du will not give up, and if he puts a peerless exercise in front of him but does not cultivate, isn't that a great waste?

The retreat ended in just three days.

Seeing Chu Du come out so quickly, Shi Zhihan and Wu Jinlai were both surprised, and only Shi Xiuxiu was overjoyed.

"Young Master, why did you get out of the customs so quickly?" Wu Jinlai asked.

Chu Du casually found a reason and said: "The cultivation is a little unsmooth, and I am upset and irritable for a while, so I simply come out to breathe." ”

"By the way, I'll go to the Heavenly Treasure Pavilion now, you can help me go to other stores to see if I have any materials on it, and if so, buy them for me." Chu Du said to Wu Jinlai, and at the same time handed him the jade slip with the materials he needed, and Chu Du took out 5 top-grade spirit stones and handed them to Wu Jinlai.

Wu Jinlai looked at the five top-grade spirit stones in his hand, his hands were trembling, this was a huge sum of money that he had never owned, now Chu Du just let him take it to buy something, isn't he afraid that he will run away with the money?

Shi Zhihan on the side also had a different color in his eyes.

"Why are you stunned, go, even if this spirit stone is placed in your hand, do you dare to escape?" Chu Du seemed to have completely seen through what Wu Jinlai was thinking, to be honest, this spirit stone was given to Wu Jinlai with the intention of testing him, and if Chu Du retreated in the future, these materials would basically have to be bought by Wu Jinlai, if Wu Jinlai had no problems this time, this matter could be handed over to him with confidence.

If Wu Jinlai ran away with Chu Du's spirit stone, Chu Du would have lost a few spirit stones to see a person clearly, but Chu Du concluded that Wu Jinlai would never run, and it was still possible to change Shi Zhihan, because only by reaching Shi Zhihan's strength could he live safely when he went out of the city, and Wu Jinlai, a small Jindan monk, went out to find death.

Wu Jinlai quickly thought of this, and followed Chu Du's footsteps to help buy things, but those few top-grade spirit stones were kept rubbing in his hands, and Chu Du couldn't cry or laugh when he saw it.

Soon the two rushed to the North District Trading Market, where Chu Du and Wu Jinlai separated, Chu Du went straight to the Heavenly Treasure Pavilion, while Wu Jinlai asked those smaller shops one by one.

Entering the Heavenly Wealth and Earth Treasure Pavilion, Chu Du didn't see Soho, and it was one of the women who served the tray last time who received him.

"Young Master Chu, the materials you need haven't collected much because the time is too short. The woman who received Chu Du spoke.

"It's okay, just give me what ones you have first, and I'd like to ask if you have anything like the Tiger Demon Core in your store, I need this kind of material right now. Chu Du said directly to the woman.

After hearing Chu Du's words, the woman smiled and said to Chu Du: "Okay, Master Chu, you go to the VIP room and sit down for a while, and I will come to you in a while." ”

After leading Chu Du to the room and sitting down, the woman went out, and Chu Du drank tea alone in the room.

didn't let Chu Du wait long, the woman came to the room again, and at the same time held a tray in her hand, seeing the materials on the tray, Chu Du was happy.

"Young Master Chu, the materials you need are only 3 Burning Sun Grasses, and the Burning Sun Grass is more abundant in Vermilion Bird Mountain, so this one is relatively easy to find, and the others are not available for the time being, as for the materials similar to the Tiger Demon Core that Young Master Chu said, we still have a lot of them here. The woman said to Chu Du.

Then she squatted down again, put the tray in front of Chu Du, pointed to two of the materials and introduced: "These 3 fruits are ghost fruits, directly swallow 1 to enhance spiritual power in 3 layers in one day, can be superimposed, as long as you are not afraid of being strangled to death, this is the demon pill of the four-pupil merman, and the four pupils are the fourth-level demon beasts, but the spiritual power of the mermaid is stronger than the tiger of the same level, so these 5 demon cores are of a higher grade than the demon core of the tiger." ”

"Hehe, isn't it just that the price is higher, I understand, let's talk about how many spirit stones" Chu Du said with a smile.
