PS: Thank you for the reward from the Venerable Brother Ling Xu!

The creeper's mouthparts shot like arrows, whistling like wind and thunder as they slashed through the air.

Cao Zinuo's face was solemn, and the long sword in his hand swung like a ripple of water, drawing an arc very softly, and then another arc, as if countless circles were ringing in the air, but the crawler's mouthparts seemed to be stuck in a quagmire, and he actually trembled and stopped in mid-air.

These swordsmanship Cao Zinuo clearly didn't use much internal force, but it magically stopped the attack of the creeper's mouthparts, and even Cao Zinuo himself couldn't help but smile with satisfaction.

This Tai Chi sword technique was not so magical, but Cao Zinuo used the Tai Chi Sutra, just like the introduction given by the space, after the Tai Chi Sutra was used, Cao Zinuo's Tai Chi Sword Technique power was up a notch.

These few simple moves can block the crawlers who forced him and Zhang Da helplessly before.

It seemed that because he was too satisfied, the long sword in Cao Zinuo's hand trembled violently, and there seemed to be a trace of a tiny flaw.

The sword intent dispersed, and the creeper, who was a biological weapon, immediately instinctively sensed the opportunity, and its figure jumped quickly, and its mouthparts shrank slightly like a contracted spear, stabbing out more sharply and quickly again.

At this time, Cao Zinuo's sword momentum was exhausted, but it was too late to return to the sword to block the attack, seeing that the crawler's mouthparts were about to pierce Cao Zinuo, suddenly, Cao Zinuo's side suddenly seemed to fluctuate like water ripples, and the crawler's mouthparts trembled again and stopped, not only the mouthparts, but the crawler's huge body also seemed to float slightly.

Cao Zinuo's figure suddenly moved, and he staggered the crawler's mouthparts and came to the creeper's side, and the long sword in his hand stabbed out quickly, still the rhythm of Dugu Jiujian, but it seemed to have a trace of indescribable and inexplicable yin and yang artistic conception.

A series of swords, all stabbed in the creeper's mouth, the powerful internal force was transported to the sword body, straight through the brain, the creeper's body floated slightly in the air, although it was roaring again and again, but there was no room for dodging, it was actually killed by Cao Zinuosheng.

Tai Chi swordsmanship, the wall of the heart, and the primary gravity technique, these three skills have been fully used and mature, but unfortunately there is nowhere to try the flying skateboard.

Cao Zinuo no longer looked at the corpse of the crawler on the ground, but slowly calculated the gains and losses during this time.

Tai Chi swordsmanship cost him 50,000 points of strengthening, but in addition to learning Tai Chi swordsmanship, he fused the inventory of Tai Chi boxing scriptures, and had a great understanding of Tai Chi Yin and Yang, although he couldn't see any benefits for the time being, but he had a hunch that it would be of great use in the future, so the Tai Chi swordsmanship was extremely cost-effective.

The cost of the Heart Wall and the Primary Gravity Technique is much larger than that of the Tai Chi Sutra, and it was also at the time of exchange that Cao Zinuo realized that Alice's ability in biochemistry was just mental power development in space.

After the development of telekinesis, there is still force field control, momentum use, and then all kinds of abilities, this spiritual power Cao Zinuo wanted to exchange something similar to the immortal body at first, but after looking at the price, Cao Zinuo was very helpless to find that unless he only exchanged that one, the 300,000 strengthening points are really not enough, and if it is not exchanged to the extreme, the immortal body is to increase the recovery power a little, it is better to sell some drugs in the space to bring the habitual use of the body.

Immediately, Cao Zinuo turned around and chose the defensive category, from the lowest level of defensive spiritual power to the current wall of the heart, originally, if it was exchanged according to the defensive exchange, after Cao Zinuo was exchanged for the wall of the heart, if it was equipped with a golden bell jar, the effect of defensive martial arts such as the absolute golden body would be better, but the same problem, starting from the lowest-level conversion of the internal force of enhancing the physical body's defensive power, it would take tens of thousands of strengthening points to exchange it until the defensive martial arts.

However, after exchanging the Tai Chi Sword Technique and the Flying Skateboard plus the Heart Wall, it is impossible for Cao Zinuo to exchange it for a better defensive martial art, so Cao Zinuo might as well exchange for a spiritual power application method that can be used with his martial arts.

In the end, Cao Zinuo chose the primary gravity technique, which requires the use of spiritual power that can only be exchanged for force field control and weight use.

And the facts have also proved that there is no problem with Cao Zinuo's exchange, and he can get unexpected convenience by using the primary gravity technique to attack with martial arts immediately after defending against the enemy's attack on the wall of the heart.

At this time, Cao Zinuo's strength is not known how much it has increased compared to before the exchange, for example, if he encounters the scene at the end of Biochemical 1, Cao Zinuo can easily face the joint attack of Zhang Da and a mutant creeper, and kill the two together effortlessly.

Of course, the improvement is great, but the consumption is also great, exchanging these things, together with entering the world of biochemistry 1 for a period of penance, Cao Zinuo's huge wealth of 31,400 enhancement points is still in the early 60,000s, and then, Cao Zinuo ruthlessly exchanged another 5,000 points of gold, plus some guns and ammunition, and practiced the use of firearms, and finally only 45,700 enhancement points remained.

This figure is still a lot of wealth for most newcomers, but for Cao Zinuo, it is really not enough to do anything.

After the training, Cao Zinuo returned to the private residence in the space, and rested leisurely for two more days.

"Ilya, Sunrise's sister is actually called Ilya, and the alien's name is really strange."

complained a word, Cao Zinuo accepted the invitation, and in the next second, the space changed, and the world in front of Cao Zinuo changed suddenly, and there was no trace of the comfort of the private residence in the space.

The unbearable heat and annoying noise emerged, and Cao Zinuo looked up, but outside was a prison scene, soldiers in old military uniforms, messy and dirty environment.

With just one glance, Cao Zinuo had already slightly guessed what kind of world this world was, and everything in front of him was really familiar and couldn't be more familiar.

"It's actually a prison, and our first task is probably to escape from prison, but I don't know how much space will limit us."

Next to him, the girl's crisp voice sounded beside her, Cao Zinuo turned her head, just in time to see the beautiful and cute sister's exquisite side face, the calmness on the girl's face at this time was like the naughty little girl next to Sunrise.

Cao Zinuo was slightly stunned, and then he wanted to organize the language to speak, but before he could say anything, the voice of the guide in his head had already sounded, and Cao Zinuo's ordinary plot finally began.
