In the underground base, the creeper's blood had already filled the laser channel, and in the warehouse, Cao Ziheng's eyes slowly opened, and a trace of regret appeared in Cao Ziheng's eyes.

"How."

Next to her, Zhang Meier looked at the regret in Cao Ziheng's eyes and couldn't help asking, the woman's expression was also extremely nervous at this time, although she never left the door, she still observed the crawlers outside, but her eyes couldn't help but aim at Cao Ziheng.

"As you guessed, it is restricted, the Dragon Elephant Prajna Gong is stuck in the thirteenth level, it should be that only by upgrading the Nine Yang or Nine Yin can the level be raised to the third level of Qi Training."

Cao Ziheng's brows furrowed slightly, "Perhaps, upgrading has always been seen as simple by us, when practicing Qi at the first level, it is enough to break through the limit with only one internal skill, while the second level of Qi training requires two, and the third level of Qi training requires three, and if the level does not break through, then, no matter how far you cultivate the best martial arts, it is impossible to break through again." ”

"If that's the case, it can explain why this mixed area is the worst, but there is no chance to improve systematically here, it seems that we have to find a way to go back to the previous village."

Zhang Mei'er's brows were also furrowed, but this kind of environment cannot be solved by any resourceful calculation, this is a pure hardware problem, and there is no way to change what conditions there are in the village.

"Kill back, now my strength should not be afraid of the third-level Qi training masters, and according to the information you get, even if the high-level world sends people down, the strength will be suppressed at the peak of the third-level Qi training, even if there are some more ingenious power use skills, it will definitely not help me."

Cao Ziheng's eyes flashed with a fierce look, strength, for him now, it is not entirely for survival, becoming stronger itself is also his tireless pursuit, so he naturally will not let others block his way to become stronger.

The most important thing is that in the village where Zhang Yuan is located, although there are many masters, there are no masters who can play a decisive role, and the masters of the second level of Qi cultivation still have a lot of threats to Cao Ziheng before, and there is no longer any threat to Cao Ziheng, who is now a dragon like a dragon.

"It's not a big problem to kill back, but after passing the small level, we will enter the high-level world, and we will still meet the people of the Bloody Hand Society, but what should we do when the time comes."

Zhang Mei'er spoke again, but there was a thoughtful look in her eyes.

"Assuming that our inference is correct, and the level is related to the improvement of the martial arts cultivated, then, we only need to learn a few more top-notch martial arts, with your strength, this is not difficult, but we are worried that our inference may not be completely correct, or may not be applicable to the higher worlds."

After thinking for a while, Zhang Mei'er spoke again.

"Don't think too much about it, kill all the creepers in this base first, and then let's leave, and occupy the Bloody Hand village for the time being, as for the rest, let's talk about it later."

Cao Ziheng got up slowly, turned around and walked to the motherboard of the red queen, and then quickly lifted the motherboard of the red queen out of the ground, and took it out and put it into his storage ring in the angry cry of the red queen.

And when Cao Ziheng did this, Zhang Meier was not the slightest strange, the red queen, the top intelligent brain, must be a treasure on the side of those technological evolutionaries, and it can be sold at a good price.

Putting away the red motherboard, Cao Ziheng turned around and walked towards the outside of the laser channel, and Zhang Mei'er followed with a faint smile on the corner of her mouth.

Martial arts need to be cultivated, and if you want to really improve quickly, you need to fight and kill.

At this time, both of them were injected with viruses and serums, but they had a certain degree of resistance to biochemical viruses, and even the toxins of the creepers could not be 100% threatening to the two of them.

This is the perfect time to increase your combat experience.

Of course, there are not many creepers outside now, so Cao Ziheng and Zhang Meier went out hunting, although it would be a little thrilling, but there was no danger to their lives.

Soon, the two of them have swept the entire base, there are many people in this base, and there are many zombies, but they can't despair Cao Ziheng and Zhang Meier as desperately as the original book gives the protagonists despair.

If you can avoid it, you can avoid it, and if you can't avoid it, you will kill it directly, soon, Cao Ziheng and Zhang Meier have killed all the creepers in the base, and at the same time, Cao Ziheng and Zhang Meier received a reward for the space, because Cao Ziheng chose to share it with Zhang Meier after receiving it, so both of them received rewards.

Just when the two of them killed the creeper and were about to return, outside the aperture in the village, several disciples of the Hero League were quickly nervous, looking at the slight fluctuation of the aperture, a disciple of the Hero League had already rushed towards Tang Ran's house.

Soon, Tang Ran, who was surrounded by Hua Jianfeng, Chen Yang and Yang Yang, was brought around the aperture, and with the violent fluctuation of the aperture, the figures of Cao Ziheng and Zhang Meier finally appeared next to the aperture.

"Ziheng, is the plot over, come, follow me to my house, there is something to discuss with you."

Seeing Cao Ziheng and Zhang Mei'er appear, Tang Ran immediately walked up and spoke, and while speaking, he reached out to pull Cao Ziheng affectionately, trying to invite Cao Ziheng and Zhang Mei'er enthusiastically.

"Director Tang, don't you ask me why none of the newcomers to your Hero League have come out?"

Looking at Tang Ran's enthusiasm, Cao Ziheng's eyes showed a strange look, and he looked at Tang Ran with blazing eyes, and on the other side, Zhang Mei'er was smiling like a flower, but she stood there quietly and didn't say anything.

"Every time the plot doesn't die, if I have to ask every time I die, and even blame others for it, then this village has long been occupied by resentment and hatred, as the person in charge, I don't understand anything except for Wan Ke, a fool, most of my things are handed over to others to do, such as Hua Jianfeng, such as Yang Yang, such as Chen Yang, etc., and I am alone most of the time."

Tang Ran laughed, said in an extremely indifferent tone, and took Cao Ziheng's hand slightly as he spoke, as if he wanted to pull Cao Ziheng away, but the latter seemed to be embarrassed to refuse, and also took two steps forward.

"Speaking of Wan Ke, by the way, why don't you see this bastard boy, let him come out to see me, director, don't say that Wan Ke is not there, I don't believe it, that bastard is your loyal follower, it is impossible to stay away from you."

Cao Ziheng looked at Tang Ran with curiosity, and then looked at the three of Hua Jianfeng not far away. "Eh, Chen Yang, Yang Yang, Lao Hua, hurry up and bring Wan Ke to me, this bastard boy, dare not come to pick me up, if he doesn't come today, I won't leave, and I will also pull the director to wait here, don't do anything."
