The ten-minute countdown to the service passed quickly, and taking advantage of this last time period, Shen Shao and his party also had a rare wave, leaving the stronghold to find an infected body and playing a wave of life and death speed.

Eventually, at the end of the countdown, they returned to the stronghold, and disconnected after saying goodbye to each other breathlessly.

Suddenly, the entire colony fell silent.

Tang Yan, or rather Lin, who stayed here and did not disconnect, stayed quietly for a while, and then suddenly turned his gaze to the direction of the World Tree outside the stronghold, "The World Tree has begun to upgrade. ”

The moment the words fell, half of his consciousness was in Lin's body and Tang Yan, who was thinking at his speed, and his consciousness couldn't help but start to get excited.

Hey! It's finally time to wait for this day!

The devil knows how much psychological pressure he was during this time.

Well, now Mom doesn't have to worry about me suddenly GG with the World Tree because I can't complete the mission!

Although he was a little confused by these World Origin Collections in this final stage, wouldn't it be enough to have a happy ending!

"How long does it take to upgrade?"

Taking a deep breath and adjusting his emotions that were a little excited now, Tang Yan's consciousness asked.

Hearing this, Lin was silent for a moment, "This is the first time to upgrade, and it will take at least an hour. ”

Receiving this reply, Tang Yan was slightly silent.

An hour, fortunately, it's not very long, it's completely okay to wait, and as for the waiting period, he can think about what to update during the open beta period.

But before that, there's another thing to consider.

"Is there any evolution in the infected body this time?"

Before, I had only paid attention to Lin using her ability to kill these infected, and I had never understood the state of these infected.

Hearing his question again, Lin was silent again for a moment, and then spoke again, "Yes, there are quite a few of them, but they are generally only second-order infections, and the danger level is not too high. ”

Receiving this reply, Tang Yan breathed a sigh of relief.

Fortunately, if you can hear from the other party's mouth, the danger level is not too high, so it's not too much of a problem, anyway, he won't be ready to play in person anymore, and these will be left to the players who move in at that time to get it done.

Simultaneously feeling what Tang Yan was thinking at this moment, Lin couldn't help but roll her eyes and speak, "...... The level of danger is not high, but for those of you who have already taken imperfect genetic medicines, others are still dangerous! In addition, this is only for ordinary and second-order infectants, and there is a special individual in this batch of infected. ”

Tang Yan, who was still thinking about what was going to happen next, was stunned when he heard this.

The first half of the sentence is left alone, and the second half of the sentence is a special individual?

Without waiting for him to ask, Lin's response had already sounded again, "It's a mutant infector, and the direction of the mutation is a bit special, and I already have some thinking ability." ”

Hearing this, Tang Yan's thoughts froze directly.

Damn! An infectious body with the ability to think!

This is definitely not good news!

Fortunately, there is only one in number, which makes it a lot less difficult.

"Can it be solved?"

After a long time, Tang Yan, who came back to his senses, asked.

Lynn shrugged her shoulders when she felt this inquiry, "Yes." ”

Before Tang Yan, who got this response, had time to get excited, the second half of Lin's words rang out again, "If you want to change gender." ”

Suddenly, Tang Yan: "??? ”

What, what?

Changing genders?!

Why did it suddenly become a change of gender?

Before she could ask this question, Lynn's response had already sounded again. "I forgot to remind you before, my ability is not only to challenge your body's limits, but also to assimilate your body's organs......"

In an instant, Tang Yan was shocked.

it!

Wait a minute! Anabolic organs!

At this moment, Tang Yan, who was half conscious in Lin's body, directly controlled Lin's body in shock and sat up.

This situation did not excite him, but made his eyes widen even more.

This is not a good sign, he can control Lin's body, it can only show that his consciousness is now more and more in line with Lin's body, in other words, the degree of assimilation has deepened!

However, having said that, because of the sight blocked by the clothes before, I didn't realize that the figure covered under Lin's clothes was so good! Such an explosion!

Coupled with that face of disaster and feminine voice, this is definitely the perfect lover template that all men dream of.

Moreover, this snow-white hill and ravine, which looked down, was a little too thought-provoking, anyway, Tang Yan couldn't help but make a swallowing motion, and his hands involuntarily moved towards the snow-white.

Before he could reach it, Lynn's voice suddenly rang out, "What are you doing?" ”

The sudden inquiry made Tang Yan's hand stretched out by the ghost god stiffen instantly, and after a moment of silence, he smiled a little wryly, "What, move your body, it's a little stiff ......"

“…… I'm telling you serious things, but you're thinking about this? ”

Tang Yan: "......"

I was wrong!

Resolutely admit a wave.

In the face of Tang Yan, who apologized so quickly, the corners of Lin's mouth twitched slightly, and after a moment of silence, she did not continue to dwell on this matter, but moved her body directly from the upstairs, placed it on the sofa in front of her, and spoke again, "...... Alright, I forgot to remind you about the world tree upgrade. ”

This instantaneous transfer scene made Tang Yan a little unresponsive for a while, and when he came back to look at his body in front of him, he couldn't help but have a trembling expression on his face.

Looking at his own body, using the other party's body, it is so weird for Mao's face!

Feeling the other party's thoughts flying at this moment, Lin took a deep breath and shouted at the other party after a while, "...... Listen to me! ”

Tang Yan, who came back to his senses in an instant, subconsciously controlled his body and sat down obediently, looking at each other with a good baby on his face.

Lynn: "......"

She was suddenly a little tired, if it weren't for the fact that the other party's thinking speed would plummet more than ten times after changing back into her body, she would have changed back by now.

Sighing lightly, she looked at her body with a good baby expression and spoke, "The World Tree upgrade will unlock the blueprint, but this blueprint needs another world origin to learn, the higher the level of the blueprint to learn, the more the number of world origins required, for example, the current 20,000 points of world origin are at most a little technology point, and after the world tree is upgraded, there will be more than one blueprint unlocked, if you want to learn them all, a little technology point is not enough, do you understand?" ”

Hearing this, the expression on Tang Yan's face finally became serious.

According to Lynn's meaning, when the World Tree is upgraded, he will only be able to unlock one of the technologies!

"How are technology points calculated?"

After a moment of silence, he looked at the other party and asked rhetorically.

"Fixing 20,000 copies of the World Origin is a little bit of technology."

Hearing this reply, Tang Yan couldn't help leaning back, sinking himself into the sofa and falling silent.

I thought that after collecting 20,000 copies of the World Origin and upgrading the World Tree, it was over, but it turned out that this TM was just the beginning!

The most important thing is that he still doesn't know how many layers and forks the World Tree's technology tree has, if there are more of them, the future will be a little gray.

Now we can only hope that the players who come in will be able to help a little bit.

After discussing the follow-up issues of the World Tree upgrade for a while, Lin suddenly stopped and looked in the direction of the World Tree outside the stronghold, "The upgrade is over. ”

Hearing this, Tang Yan also quickly turned his head to look out the window, but in the direction where the World Tree was originally located, there was no trace of the World Tree at this time, which made him subconsciously flustered.

What about the My World Tree?

Why am I a big World Tree?

Obviously it was still there before! Why is it suddenly gone?

Does this upgrade of the World Tree still cause the World Tree to disappear?

Noticing the stunned look on his face, Lin calmly explained, "It's back to its original space, the reason why I was able to see it before was because of the lack of energy, and now that the energy has recovered, I will naturally go back." ”

As she spoke, she reached out and pushed away in front of her, and a familiar projection panel appeared.

"World Tree: LV1

The wood that bears the world. (Upgrades can be continued)

Every two hours, you can generate a copy of the World Origin on your own.

Remaining lifespan: 100 years

Required for the next upgrade: 20w World Origin

Current Collection World Origin: 363

Current unlocked technologies:

blueprint for the pharmacy laboratory;

Blueprint for the Genetic Laboratory;

Biochemistry Laboratory Blueprint;

Armory Blueprint.

Remaining Tech Points: 1

Tech Points Invested: 0. ”

looked at the projection panel that the other party made, and the content on it made Tang Yan stunned.

Generate the origin of the world autonomously every hour!

Can the World Tree be upgraded to automatically generate the World Origin?

That's good news!

It's just a little less for these two hours, and it's only 12 o'clock after a day and a night.

However, it is a considerable number over time.

Moreover, it also makes it a little less difficult for him to obtain technology points.

As for the remaining life span of the next hundred years, that is, in the next hundred years, he doesn't have to worry about the GG problem anymore?! And the number of world origins required for that level 2 upgrade is 200,000......

mmp！

Directly multiplied tenfold!

If you calculate it this way, wouldn't it cost two million for the third level!

Looking at the current number of collections, 363......

Sadness!

Thanks to this level, there are not many technologies unlocked, only four, otherwise, he really doesn't know how to order this technology point.

But then again, it's not good to have only these four!

Potions, genes, biochemicals, ordnance.

Which one looks awesome!

Originally, I thought that I would be able to unlock the potion at the first level, but I was already thankful.

Well, now that the potion is really unlocked, it's still a lab blueprint, but it also unlocks three other technology blueprints that are completely comparable.

Looking at the four gray technology options, he felt a little pain in his brain, and the choice was difficult.
