In fact, Lin Chen's temporary release of the exchange of restricted items was only prudent. It's a matter of his loved ones, and he can't accept any slip-ups.

Originally, with the current foundation and security situation in Weicheng Base City, if he was in charge when the zombie catastrophe occurred, he would not have any worries. But out of the desire to train his sister and his subordinate cadres, he started his expedition to the west at this critical juncture. But he was afraid of self-defeating. So there is the current scene.

Lin Chen's idea and plan was to strengthen the combat power of all his subordinates before the disaster occurred, and their chances of survival in the disaster would be greater. This can also further consolidate the evolutionary foundation of the fifth-level upper-level personnel, allowing them to advance to the sixth level on the eve of the disaster.

In terms of biological evolution, all evolved creatures can use resources or time to pile up to level 5 if they are not too qualified or too lazy. But after the fifth level, the first level is a big hurdle. If you want to advance after level five, qualification occupies an extremely important position. The further back you go, the more important qualifications become. If there is no special chance, more than half of the capable people will be trapped at level 5 all the time. Lin Chen in his previous life had been fighting for ten years in the last days, and he was still at the sixth level, and he was never able to break through to the seventh level, which is a clear proof of this.

Of course, Lin Chen in this life will no longer have worries about this. But he still needs to explore the path of evolution after level seven.

There is no doubt that in the Sky Wolf Army, the masters who are already at the top of the fifth level are all qualified enough. These masters can easily advance to level six. Lin Chen planned to make them rank six masters on the eve of the disaster. At present, there are less than those who are at the fifth level, and it is remarkable that half of them will be able to advance to the sixth level in the future.

With Lin Chen's current development speed, when a disaster occurs, he will go out two or three thousand kilometers at most. That's just an hour's flight into the sky. Before going out of tens of thousands of miles, it was more convenient for Lin Chen to return to Weicheng.

Therefore, Lin Chen opened the warehouse again and released grain, so that all his subordinates could speed up their evolution.

To put it bluntly, the most important purpose of Lin Chen's move is to ensure the safety of his important relatives as much as possible. His parents and sister are both innate evolutionaries, and their evolutionary potential can reach at least level eight. With the support of his resources, there is also a high chance of becoming a ninth-level legendary master. As long as they advance to level 6 on the eve of the disaster, the level of security will be greatly improved.

"Alright. The purpose of my return this time is to bring you the flesh of the nuclear beast. You guys do what you plan and I don't comment. Now, I'm going back to Dapeng City. The radiation zone has not yet been cleared. ”

After Lin Chen put down a large number of supplies, Feitian carried him away through the air.

"My brother is so relieved of us? He's not afraid that we'll mess things up for him? Lin Ya looked at the night sky and said unhappily.

Although Lin Ya has become an iron-blooded commander, she still has a deep attachment and dependence on her brother Lin Chen. If possible, she doesn't want to be a majestic military commander, she just wants to be a small soldier in front of her brother's tent.

Guo Jiayi and the others smiled silently. It seems irresponsible for the boss to leave Weicheng and launch the western expedition alone at such an important moment. In fact, isn't the real intention of the boss to train them?

They didn't believe that Lin Ya couldn't see it. Lin Ya is just coquettish. In the world today, there are really not many people who are worthy of Lin Ya to show her childlike appearance.

Lin Chen left Weicheng and went to Yushan in the northwest of Weicheng again. The Yushan zombies haven't been harvested for several days.

This time, Lin Chen was a little longer delayed in Yushan. He harvested almost all the zombies that had reached the middle level of the fifth level. A total of more than 40 fifth-level upper-level zombies and thousands of fifth-level middle-level zombies were harvested.

"When Ah Yang advances to the sixth level, this hard work can be handed over to him to do." Lin Chen thought in his heart.

Yu Yang's unknown skills include stealth and teleportation. There are also short gods in hand. As long as he reaches level six, all zombies below level six can be killed silently in seconds. Even if you accidentally alarm the corpses, you can also teleport to escape. It just happened to be perfect for the task of harvesting the zombies in Yushan.

The key is for Yu Yang to carry out the harvesting task, which can be kept confidential to the greatest extent.

In this way, Lin Chen didn't have to worry about being trapped in the Western world by something and couldn't come back for a while, so that the Yushan zombies would take the opportunity to sit big.

......

The eradication of the remaining mutant beasts in the radiation area did not achieve Lin Chen's intended purpose. The farther you go to the center of the radiation zone, the taller the radiation mutant becomes. Of course, it is also becoming more and more ferocious.

If Lin Chen had ignored the death loss of the soldiers, he might be able to strangle all the radiation mutant beasts the next day. But things haven't rushed to that point yet, and Lin Chen doesn't want his soldiers to suffer too many casualties for the time being.

Besides, the soldiers of the Pakistan Railway War Regiment are about to return to China, and Lin Chen doesn't want too many poor people to be left in a foreign land.

Yesterday, in less than half a day, they killed fifty or sixty thousand mutant beasts. And today, after a whole day, it is not much different from yesterday's record.

"Depending on the situation, it will take at least two or even three days to get rid of these monsters. No, I can't afford to stay here too long. If you don't want to let the soldiers die in large numbers, you have to find another way. Lin Chen was thinking in the tent.

"That's it, let's advance the time for Emperor Liu's promotion a little earlier. Anyway, the resources are enough now. Lin Chen finally made the decision to let Emperor Liu advance to the ranks.

The plan was set, and Lin Chen entered the world silently.

After Emperor Liu absorbed one-third of the essence blood of tens of thousands of Indo-Western Capable people in the Indo-Western Kingdom last time, the level was already infinitely close to the sixth-level upper rank.

Lin Chen waved his hand, and 10 medium-grade yuan stones flew towards Liu Huang.

Liu Huang immediately devoured the Zhongpin Yuan Stone, and the green light on his body was shining, and the breakthrough was imminent.

But the green light keeps blooming, but it doesn't break through.

Lin Chen moved his mind again, and a formless and colorless world energy fused into Liu Huang's body. This time, the world energy consumed was not much, but it was like a little spark, activating the Liu Emperor.

The green light rose violently, then contracted. Liu Huang, break through!

After the breakthrough, Liu Huang's body flashed with five-colored brilliance, and he looked very mysterious. Soon, this mysterious aura disappeared without a trace.

Liu Huang's traits determine that it can achieve breakthrough and peak, as long as the resources are sufficient.

Lin Chen smiled slightly, and the 400,000 high-energy zombie bodies harvested the day before yesterday immediately flew towards Liu Huang in a steady stream. Liu Huang's energy reserves are constantly rising.

When Liu Huang's energy could not rise, it had already devoured 140,000 high-energy zombie bodies. Its rank has reached the peak of the sixth upper rank. Its control, defense, and lethality have almost doubled from the original base.

Lin Chen asked Emperor Liu to continue to devour the remaining more than 200,000 high-energy zombie bodies, and divide them into corresponding levels.

When all the high-energy zombie bodies were devoured, Liu Huang divided into twelve branches.

"It's fine. Although it is a bit of a pity to consume the high-energy zombie body that you have finally obtained, it is worth it. This has allowed me to save countless resources. Soon, when Liu Huang is promoted to the seventh level, it will be a group battle big killer. Lin Chen's eyes lit up as he looked at Emperor Liu, as if he had seen the wonderful scene of Emperor Liu's countless tree roots that had reached level seven turning into divine weapons and wantonly slaughtering enemies.

Even now, as long as Lin Chen is willing, he can let Emperor Liu advance to the seventh level and dominate the world. However, it seemed that such a small level breakthrough required Lin Chen to pay most of the current beast meat reserves. The countless crystal nuclei were pure bioenergy, and Lin Chen was reluctant to use them for Liu Huang's promotion for the time being.

The main thing is that the situation is not so urgent now.

It's really a matter of life and death, where will there be so much care. As long as it is necessary, on the premise that the world does not collapse, Lin Chen can give all the resources in the world and push the level of Liu Huang as high as he can. This is Lin Chen's last trump card.
