The small saplings transformed by the essence of the world are easily absorbed by the system after losing the protection of the Dryad statue.

Early this morning, Gu Qing returned to the long-lost main base of the Valley of the Wicked, enjoyed Chef Fan's food, and just sat on the gilded chair when he heard the prompt of the system.

"Host, the upgrade conditions have been met, and the world-destroying system can be upgraded."

Gu Qing's eyes lit up, and then he said, "Upgrade immediately." ”

While waiting for the upgrade, Gu Qing went to the Lingyun World again, and he wanted to see how various matters were going.

The world of Lingyun fell into a dead silence, and after the Zerg devoured all the resources of this world, they fell into a deep sleep to reduce the consumption of energy.

The whole world seems to be a lot colder, that is because the two suns in the sky have become one, and the sun created by the tree temple has been completely wrapped in the Zerg Dyson ball, and the sun is still shining and heating, but only the Zerg can enjoy this light and heat.

The other sun is far away, different from this Tree Temple brand sun, it is in the void, it is completely a celestial body born from the void, it seems to be only a little farther than the tree temple brand sun, but the actual distance can be calculated in light years, and the current Zerg can't help it.

Compared to the deserted Lingyun world, the breeding world occupied by Jerome is much more lively, and eighty percent of the plant buildings here have been retained by Jerome, these are all proven harmless buildings, which can be completely reused, including plant buildings that provide human habitation and buildings that deal with human corpses to collect souls, but they need to be transformed again, and the whereabouts of those souls are transferred to the energy oven.

Then let those dead humans be judged to be killed by the Legion of the Exterminator, so that not only can you harvest a steady stream of soul resources, but also have a lot of kill points in your account.

This also makes up for some of the shortfall that was consumed by Jerome.

In the breeding world, in addition to the light film space door leading to the spirit world, there is also a light film space door, and Jerome speculates that behind it is conveniently the location of another tree temple's arsenal.

Considering that its nature is the same as that of the Lingyun World, it is tentatively named the No. 2 Lingyun World.

These days, he has been planning how to invade the second spirit world, Elizabeth was very excited to eat it when she heard the news, but Jerome meant to stabilize the breeding world first, because according to the observation of the second spirit world, the second spirit world did not know what happened in the breeding world.

After stabilizing the situation and upgrading the system, we will attack the No. 2 Spirit Yun World in a big way.

After Gu Qing learned about the situation, he chose to listen to Jerome's opinion, so that he should be more conservative and improve the power of the World Destroying Base as soon as possible, after all, he was doing things in the rear of the Tree God Temple, and now he was just slaughtering a Spirit Yun World and quietly occupying a breeding world, maybe the Tree God Temple would not be able to take action against him for a while, but when the Zerg was powerful, the Tree God Temple would definitely realize the seriousness of the matter.

Gu Qing didn't want to directly face the real high-end power of the Tree God Temple, so even if he retained the power of the World Destroying Base in the end, his sphere of influence would inevitably shrink and close.

After calming Elizabeth, who was a little anxious, and after everything was dealt with, the system's prompt also sounded, telling Gu Qing the news that the system upgrade was completed.

Unconsciously, the system has been upgraded to level five, Gu Qing hurriedly returned to the base, he wanted to see what new things would appear in the system of level five, and it was best to appear a building that crossed the world, this is the urgent need, after all, crossing the void to find other worlds, the danger is too great.

Even if it is a Zerg, if it wants to evolve to a stage where it can cross the void, it will not be able to do it in a while, and the premise also needs sufficient energy support.

"System, which displays the data of the five-level system."

"Okay, host."

"One more chance to draw a superweapon."

"Reserved Class: Terminator."

"Clones: carbon-based lifeforms with intelligence, random talents. The grade is six categories: mortal product, defective product, genuine product, super product, excellent product and divine product. ”

"High-grade alien beast eggs can be advanced to supernatural alien beast eggs, and there is a certain chance of hatching alien beasts with supernatural talents."

"Building restrictions are unlocked, and all buildings can be crafted infinitely."

"The energy oven can be upgraded to a heaven and earth oven."

"New Feature in the Flesh Fusion Field: Gene Collection."

"New Building: The Gate of a Thousand Things."

"Level 6 System: One Void Fragment is required for upgrades."

After reading the introduction of the system, Gu Qing suddenly felt that many problems had been solved, first of all, the number of construction manufacturing that limited the development of the World Destruction Base.

The key production center, in the fourth-level system, is only allowed to build five, which is completely insufficient in the development of the power to today's extinction base, which is why Jerome has been emphasizing waiting for the system to upgrade before making a big move, because he also thinks that the fourth-level system can't support so many buildings, but the fifth-level system must be able to, and as soon as the restrictions are opened, the alien beast legion under his command will have an explosive increase in combat effectiveness in a short period of time.

Even if the high-level alien beast egg advanced to the supernatural alien beast egg, it didn't make Gu Qing's attention stay longer, what he was most concerned about now was the heaven and earth oven advanced into the energy oven, the new functions added to the flesh fusion field, and the most important thing - the gate of Daqian.

The rice should be eaten in one bite, and the questions should be asked one by one, Gu Qing began to ask the system from top to bottom: "Introduce the heaven and earth oven." ”

"Host, the Heaven and Earth Oven is an advanced version of the Energy Oven, and the cost is extremely expensive, but the complete version of the Heaven and Earth Oven can even directly refine a world, but if you want to successfully advance to the Heaven and Earth Oven, you still need to collect five kinds of divine fire to successfully advance."

Gu Qing frowned a little when he heard this, the power of the Heaven and Earth Oven could indeed be affirmed, but this time it seemed that it was like the previous spiritual radar, and there was a precondition needed to complete the advancement.

"What divine fire?"

"The divine fire is used as the power resource of the heaven and earth oven, there are many divine fires in the heavens and ten thousand worlds, the host can find it by itself, and the level of the divine fire evaluation will also affect the quality of the heaven and earth oven in the future."

According to the introduction of the system, Gu Qing knew that as long as he came into contact with the divine fire, the system would give him a hint, no matter what kind of divine fire, as long as he collected enough five kinds, he could support the normal operation of the heaven and earth oven.

"Without divine fire, can't the heaven and earth oven be produced?"

"Of course not, host, but the Heaven and Earth Oven costs 100 million kill points and 5 million units of spiritual rhyme, and it can't work properly without the divine fire as a drive."

Gu Qing couldn't help but secretly smack his tongue when he heard this price, it was indeed very expensive.
