When the hot summer was coming, Xiao Qi was able to research the seedless watermelon, which really surprised Chu Chen!

But then again, the weather outside was almost like cooperating with Chu Chen, and since all the crops in the outer city were recovered, the weather began to get hotter and hotter day by day.

The reservoir on the west side of the base was also transformed by Shi Yingying at Zhang Yuan's suggestion - the fresh water in the reservoir was converted into a whole piece of ice.

For Shi Yingying, this process is not cumbersome, with the help of Long Jing, the project that originally took several days, Shi Yingying can complete it in more than a day.

It's just that the transformation is not considered to be the completion of the task, and Shi Yingying needs to continue to maintain this state for at least three days before the dragon crystal can be finalized.

And it is worth mentioning that the green dragon shadow in the dragon crystal has obviously become a little larger, and it has become more vivid, and what is even more surprising is that the green on its body has actually begun to change to white.

The reservoir has condensed into ice, which means that Chu Chen has decided to shrink the next step of development and prepare to survive this scorching summer first.

Thinking about the scene a few months ago, when the cold snap hit and the heavy snow covered the city in an instant, Chu Chen didn't think that this hot day would be much better.

Therefore, in the last few days before the arrival of this hot summer, Chu Chen took out the mutant vines he asked for from Yu Sheng and gathered all the druids, uh...... Chen Nan doesn't count, he has now been incorporated into the 'Hidden Sect'.

Subsequently, Chu Chen gave an order to Xiao Qi to arrange these druids outside the city wall and stand in a circle around the city wall of the base.

After they all stood up according to Xiao Qi's order, Xiao Qi looked at Chu Chen and saw Chu Chen nodding heavily.

Xiao Qi immediately took a deep breath and whispered to Cao Rong beside him, "Let's start!" ”

After saying that, Xiao Qi squatted down and gently buried the mutant vine in his hand in the ground under the city wall.

Cao Rong also made exactly the same move, and buried the same mutated vine in the ground in front of him.

The two of them took a few deep breaths, stretched out their hands and put them on the root of the mutant vine, and began to frantically urge the natural force in their bodies to control the crazy growth of the mutant vine.

Under the urging of the two of them, the two mutant vines, one to the left and the other to the right, grew rapidly, spread, and climbed out.

The vines soon spread in front of the druids beside the two, and the two druids also gasped excitedly a few times, frantically urging the force of nature against the vines that were growing rapidly in front of them.

Under the control of these two druids, the mutant vines sprouted branches, slowly connected to the ground, and then dug into the ground, turning into the roots of the vines.

Soon, the two mutant vines circled the base, and only the city gate was located, which was controlled by the druids and bypassed from above the city gate.

Correspondingly, in front of each druid, the mutant vines sprouted branches, dug into the ground, and grew into roots.

Before the operation, Xiao Qi had already passed the anger with all the druids, and this mission has come to an end for the time being, and he can rest for a while.

……

Half an hour later, all the druids' mana was restored to full value, and this mission has entered an important link!

With Xiao Qi's shout, all the druids stood up, moved a few times, and once again put their hands on the root of the mutant vine.

Xiao Qi took the lead in activating the power of nature in his body and began to give birth to the mutated vines in front of him.

The other druids, sensing that someone around them were urging the power of nature, also began to mobilize the power of nature in their bodies.

What is the result of thousands of druids working together to generate two mutant vines?

Not to mention mutant vines, even two towering trees will be blown up by this powerful force of nature!

However, the vine in front of him, although it was spread out of two mutant vines, had thousands of roots, and it was easy to receive so many natural forces.

Under the urging of the druids, all the mutated vines began to climb upward, and when they crossed the city wall, they did not fall, but continued to rely on the power of their roots to climb high in the center of the city.

In less than half an hour, most of the druids' mana began to bottom out, of course, this was a situation that Chu Chen had expected a long time ago!

I saw that the weakest druid, checked his attribute panel, and continued to mobilize the power of nature with one hand, and with the other hand, took out a bottle of magic potion from the spatial ring, bit it open with his teeth, and poured it into his stomach.

It's like there's a chain reaction, starting with this druid, every few seconds, a druid starts drinking medicine, and sometimes, there are several, or even dozens of druids, drinking medicine at the same time!

Time flew by, and in Chu Chen's gaze, the sky above the entire Ningqiu City survivor base was slowly shrouded in vines, and of course, there were countless gaps in between.

By the time the center of the base was in the sky, and the mutated vines that had climbed from all directions had gathered together, it had already been more than three hours later.

When the mutated vines came together, they immediately became entangled with each other and formed a huge green web.

Seeing that his plan had succeeded for most of the time, Chu Chen said hello to Xiao Qi, and then walked to the branch of the Business Alliance in Ningqiu City, preparing to find Zhang Yuan and ask him to hurry up and help Ningqiu City buy a batch of magic crystal lanterns and come back.

In Chu Chen's plan, spawning the mutant vines into a huge semicircular cover was only the first step.

After this step is successful, you can let the druids rest and continue to spawn mutant vines, after all, the general framework is out, and the entire semi-circular vine cover will not be deformed, just these druids need to continue to give birth to vines, and fill in the gaps between this semi-circular vine cover and the vines, and it's done!

For a long time, Chu Chen had never bothered with the shielding of the top of the base, because Chu Chen decided to use this method to block the scorching sun!

Of course, there is no need for this method, and there are not many other options, in Chu Chen's heart, once the mutated vines are burst, or they cannot form a whole green shade, then Chu Chen is ready to dig and build a basement.

Fortunately, now it seems that the plan of the mutated vine should be no problem, after all, the scorching sun has been tested before, and the mutant plant can withstand the scorching sun.

If the lighting problem is solved now, then there should be no problem this summer!

And when the hot summer passes, Chu Chen only needs to let the druids once again mobilize the power of nature and attach the mutant vines to the city wall, and then he can turn the vines above the base into a protective measure for the city wall, which is simply a double win!

……

When he found Zhang Yuan, Zhang Yuan happened to be standing at the door of the Business Alliance Branch, with a large number of survivors, looking up at the sky above the base, guessing the reason.

Seeing Chu Chen, Zhang Yuan pulled Chu Chen and kept asking about these vines, Chu Chen didn't think that this needed to be hidden from everyone, nor did he think that this kind of thing could be hidden from everyone.

Therefore, seeing that Zhang Yuan was curious, Chu Chen roughly explained to him, and by the way, he asked Zhang Yuan to help him buy a batch of magic crystal lanterns back.

Zhang Yuan was naturally full of promises, and he was also full of praise for Chu Chen's whimsy.

In fact, for Zhang Yuan, the importance of Ningqiu City is even greater than that of the Peace Forest, otherwise, he would not have brought his own nephew to Ningqiu City.

If something happens to the Peace Forest, maybe Wei Shuo will come to Ningqiu City and continue to develop the business alliance, and his status as Zhang Yuan will go to the next level in the business alliance!

But if it is the other way around, and there is a problem in Ningqiu City, then his good days for Zhang Yuan will come to an end, and Wei Shuo will cool him for at least a year and a half.

It's not that Wei Shuo deliberately wants to do this, it's just that Wei Shuo's business alliance, after all, is different from Chu Chen's dictatorship, he still has to take into account the feelings of the other members, and he has to cool Zhang Yuan for a while.

Therefore, when Zhang Yuan heard that all kinds of troubles in the base had been solved by Chu Chen one by one, he was really happy from the bottom of his heart!
