The dark clouds in the sky seemed to have dispersed somewhat, and the sky that seemed to be about to rain did not fall in the end.

The cool breeze blows on the face, sultry and full of coldness.

Yao Qiannai slashed in the zombie group, quickly lost interest, returned to the periphery, saw Tian Feng and others were releasing their abilities to deal with zombies, and paid attention around, but did not find Su Ziyan's whereabouts, and asked suspiciously: "What about the woman just now?" ”

"I've gone back, and I heard her say that the mission here has been completed, and there is no need to stay." Tian Feng truthfully relayed Su Ziyan's words that he was not willing to offend this Yao Qiannai.

"Went back? She doesn't plan to ask for the crystal nuclei of these zombies? A look of surprise flashed in her eyes, and Yao Qiannai couldn't understand what she was thinking.

There are clearly so many crystal nuclei that can be extracted here, and it would be a pity to give up like this.

Shaking his head, I really don't know whether to say that she is atmospheric, or whether to say that she is easily satisfied. But after thinking about it, since she got the crystal nucleus of that blue-gray mutant zombie, it is understandable to leave the scene early to some extent, after all, compared to that crystal nucleus, the remaining zombie crystal nuclei here are just corners.

Thinking that the crystal nucleus of the blue-gray mutant zombie was taken away by her, Yao Qiannai felt a little reluctant in his heart, even he saw such a crystal nucleus for the first time, and he was really distressed.

"Feiliang, come here!" Yao Qiannai waved his hand and beckoned a sturdy man.

"Big brother, you call me?" The man walked up to Yao Qiannai and asked.

"What is the quality of the zombie crystal nucleus here?"

The man shook his head: "The quality is average, I took a group of junior brothers to take several, most of them are of ordinary level, there are a few above the average, but not much." ”

"Huh?" Yao Qiannai's eyes suddenly burst into fine light, and he looked back at the zombies in the distance, "It doesn't make sense, the zombies here don't look weak, and they have also produced mutated blue-gray zombies, how can the crystal nucleus produced be so inferior?" ”

"Big brother, could it be that because of that mutant blue-gray zombie, the other zombies here have been overdrawn?"

"It's possible!" Yao Qiannai nodded, powerful zombies will devour weak zombies to achieve their own evolutionary goals, just like the king in the forest, within the territory of fierce beasts, it is often unlikely that there will be beasts as powerful as attack.

If you want to breed a powerful zombie, you must need countless weak zombies to fill it.

"Check again, if the crystal nuclei here are indeed not of high quality, we don't need to stay here and waste time!" Yao Qiannai gave an order, and the younger brothers below responded in a high-pitched voice.

Tian Feng, Pan Yan, Shi Daxing and the others stood aside and didn't say much, in fact, they knew that Su Ziyan had already swept all the zombies on the scene before they came, and the crystal nuclei left behind would certainly not be too good. But they won't say this, without Yao Qiannai, a strong competitor, their harvest will be better, right?

Not too long had passed, and Yao Qiannai was disappointed to get the news that the quality of the crystal nucleus here was indeed not very good, raised his hand, and left with his team with interest. As for the zombies that were cut down by him on the inside of the ice wall, he didn't check them either, after all, there were so many zombies there, and it was not suitable to pick the crystal nucleus.

"Tian Feng, Yao Qiannai, they are gone!" Pan Yan whispered.

Tian Feng smiled and nodded: "That's good, now there are only seven of us left here, how many crystal nuclei we can get depends on our own ability!" ”

"Or is it the old way?" At this time, the leaders of several other teams came to Tian Feng and the others.

"Of course!"

With the departure of Su Ziyan, Yao Qiannai and others, the scene has become the world of Tian Feng and other evolutionaries and their teams, plus the barrier of the ice wall, there are still five or six hundred zombies blocked on the other side of the ice wall in front of them, which seems extremely safe, if you are careful, it is a very good harvest area!

After finalizing the distribution plan of the crystal nucleus, the hundred or so people at the scene screamed and launched an attack on the zombie group.

……

Su Ziyan's side, the road back is much smoother than when she came, sitting on the troop transport card left for them by Yule, through the open cloak behind the car, I saw the scenery of the countryside flashing from the field of vision little by little like a picture scroll, the rice ears drooping low, dancing lightly, and a wave of sleepiness swept over for a while.

Su Ziyan threw the collected crystal nuclei to Zhang Wenming and them, and they counted them, while she looked at the gray sky at the end of her field of vision and was stunned.

As the carriage jolted from time to time, she thought of the previous battle with the mutant zombie, and the reason why she was able to use the ice hockey ball so strongly to smash it to death was actually largely dependent on the weather.

There was plenty of moisture in the air in the upper floors, which was the main reason why she was able to condense the ice ball. If you change to a clear sky, or under extremely low humidity conditions, the ten ** will not have such an effect.

"We have to find a way to overcome this limitation!" With her right hand clenching her fist slightly, Su Ziyan realized that if she didn't solve this problem, she would be very limited!

Just imagine, a person with the ability to watch the sky when she magnified her moves, the uncertainty in it is too great, and it will even bring her great disadvantages at a critical time.

In comparison, Tong Yansong's earth-based ability is much more convenient, and the raw materials he needs to cast it can be found everywhere, and if it weren't for the fact that he is not as evolved as himself, his ability is obviously more applicable than his own.

"This must change!" She secretly made up her mind.

In fact, there are only two ways to change this drawback, one is to improve their own attack methods, develop more intensive tricks, and try to maximize the effectiveness of every bit of raw materials; The other is to improve one's own control, and by strengthening control, the limited resources can be used on a larger scale.

At present, it is advisable to improve the attack method, but Su Ziyan does not have too many ideas, after all, the development of tricks is essentially related to her own control, and with her current ability, she has not yet reached the point of developing new tricks at will. Just as it is difficult to build various water conservancy projects in low-lying waterholes, it is only when the waterholes converge into a huge reservoir that all kinds of engineering ideas have the conditions to be implemented.

Among all Su Ziyan's tricks, the most physical and long-lasting is undoubtedly the ice sword, but using the ice sword to deal with zombies takes a lot of time, and the time efficiency is far from enough.

As for improving control, it is related to its own evolution, and what is known to be feasible is to absorb the corresponding crystal nucleus, which is indeed a way to "burn money".

"Ziyan, this time we have harvested a total of one hundred and thirty-six crystal nuclei, including fourteen at the middle and upper level of quality, one of the best crystal nuclei, and one cyan mutant crystal nucleus!"

Su Zhanliang's excited voice interrupted Su Ziyan's contemplation, turned around, and smiled at him: "I think so, the best crystal nuclei and mutated crystal nuclei are left, and half of the other crystal nuclei are left, and the remaining half is all taken to the trading floor to be sold!" ”

"This plan works! Not only can you exchange for all kinds of supplies, but you are not afraid of running out of reserves! Ziyan is an evolutionary, and it is very important to leave a certain amount of crystal nuclei to improve her strength! Su Zhan nodded and said.

No one is sure what will happen in the future, but they know that strength is the foundation of their lives, and the stronger Su Ziyan becomes, the more secure it will be for them!

"In this way, we can sell a total of sixty ordinary crystal nuclei and seven intermediate and upper level crystal nuclei!" Zhang Wenming thought for a while, and turned his head to look at Su Ziyan: "It's just that only half of the crystal nucleus is enough, anyway, we are not short of money at the moment, you can keep more!" ”

"Enough!" Su Ziyan shook her head, leaving more than sixty crystal nuclei at one time, and the quality was not bad, which was almost above all her original reserves.

She sighed with emotion and continued: "Counting the hundred inferior crystal nuclei and more than thirty ordinary crystal nuclei we harvested at the No. 6 position, the overall harvest this time is still good!" ”

"Yes, no wonder those combat squads like to run to the front line so much, the benefits are simply disproportionate!"

"Blessings and misfortunes depend on each other, the more dangerous it is, the higher the harvest!" Zhang Wenming sighed. This kind of trading with human heads, before the end of the world, I am afraid that only some black fields can match. No wonder some people say that the easiest way to get rich is written in the criminal law.

Su Ziyan nodded, and then accepted her own crystal nucleus, and handed over the remaining crystal nuclei to Zhang Wenming and them, and let them sell them at the trading floor when they went back later.

The truck was speeding away, and from time to time the bumps shook the buttocks and felt numb, and about half an hour later, the outline of the No. 6 position appeared in the sight of Su Ziyan and the others.

"It's finally back!"

When the car stopped, Su Ziyan jumped out of the car, stretched her waist, and stretched her body that was about to be numb.

On the side of the sixth position, the order is in order, the remnants of the zombies have been cleared, and the fortifications are also advancing little by little.

As it was approaching noon, the cooking class began to prepare lunch, and wisps of cooking smoke rose into the air.

Su Ziyan glanced at it and saw the direction where the explosion-proof car was parked not far away, and at this time, there were some people gathered there, and when she looked closely, she found that Jiang Yan seemed to be arguing with someone.
