Now prehistoric humans have thought that they have succeeded in deceiving Gu Fengchun. As long as Gu Fengchun has completed the last step, then they will finally come to an end after suffering for so long on this planet. It doesn't matter if Gu Fengchun is not fooled, since he has already coerced him to take the immortal medicine, then they can also control Gu Fengchun at any time. They already have multiple insurances, and the risk has been minimized by them.

Moreover, they already possessed Gu Fengchun's blood, and they could cultivate many good enough skins from this drop of blood. These skins have no ancient thoughts, they can come and go as they please, and the conditions are fully ripe for them to leave here. Now the last one is waiting for the cosmic shock to come. When the "tide" comes, all this will come to an end.

When walking in the endless starry sky, Gu Fengchun suddenly felt a little funny. He suddenly remembered that when he was a child, he seemed to have read an article about the earth. The article pointed out many unique places on the earth, and pointed out that in this vast universe, human beings are lonely beings.

As he grew older, this kind of "absolute" science, Gu Fengchun no longer believed in it. But after coming into contact with these mysterious things, he realized that human beings are not only not lonely in this universe, but even the statement that it is "advanced" is a bit far-fetched. Not to mention the prehistoric humans who came from the parallel universe, the high-level creatures who have captured prehistoric humans for hundreds of millions of years in this cosmic civilization, and they are all unattainable existences in this earth civilization.

Fortunately, the development of civilization is not just gradual, and sometimes it only takes an opportunity to grow by leaps and bounds. Gu Fengchun believed that as long as the information stored in his mind was obtained, human civilization would set off the fourth revolutionary progress. It's just that after Gu Fengchun weighed it repeatedly, he didn't dare to get out what he had mastered. Because he knows very well that the spiritual civilization of mankind is far from being able to master these technologies without the impulse to have other ambitions, and once these materials are published, a new round of world war will come at the same time as the development of science and technology.

If the Third World War broke out after mastering these techniques, then Gu Fengchun could basically know that during the Fourth World War, human beings might really only be able to use stones and sticks.

"This area, due to some setting reasons, the creatures that exist in our spirit body can't enter it, you have to be careful, we can only take advantage of the time you open this area, and enter it by tearing the space" A voice appeared around Gu Fengchun, this was the voice of the masked man just now. He nodded silently, he knew very well that he would definitely be followed by these prehistoric humans around him. It's just that these spirit bodies can't be seen directly by the naked eye. It was only when he was transformed into a spirit body that he could see the faint light.

The deep cosmic starry sky in front of him suddenly shattered, and a golden light suddenly appeared. Under the shroud of light. A small door that seemed out of place in the entire temple layout appeared. This small door is covered with vertical and horizontal lines, Gu Fengchun stretched out his hand to push, but he couldn't open the door.

A voice soon came from behind him: "This door needs your blood to open, and the space inside is also locked, this door can't be opened, and we can't enter." When Gu Fengchun heard the words of the prehistoric humans, he suddenly realized that this place had already been manipulated by the ancestors of the Wu clan who repaired this temple, and the prehistoric humans could not enter it at all. No wonder I was so important to these prehistoric humans.

Gu Fengchun smiled and stabbed his hand on his waist, and blood immediately flowed from his fingers. Gu Fengchun knew how to deal with this almost cookie-cutter structure, and looking at the vertical and horizontal lines on the door, he stretched out his bloody fingers.

Sure enough, as soon as the blood touched the door, the blood was immediately sucked into the ravines with a suction force, and it flowed rapidly. As soon as the blood flowed, the surrounding light became even more dazzling, and all of a sudden, Gu Fengchun's entire person was lost in the light. And Gu Fengchun was in these lights, and he didn't feel that there was too much wrong. When I looked directly at these places of light, I didn't even feel a hint of glare in my eyes. He could still see clearly, his blood running rapidly in the groove in the door, and gradually, he noticed that his own blood had also become golden.

And a faint rumbling sound also sounded dullly from the ground. The mechanism of this door seems to be already open.

Gu Fengchun took a deep breath and was about to push the door open, but he felt that there seemed to be a crisis approaching him. As soon as his heart sank, he realized that something was about to happen. He hurriedly gathered his spirit in case of an accident.

"Uh......" Gu Fengchun suddenly felt a sharp pain in his head, as if he had been smashed by a big copper hammer, and his eardrums also made a "buzzing" sound. He knew that prehistoric humans were trying to take his body!

Before taking the immortal medicine, prehistoric humans knew that they couldn't take Gu Fengchun's body at all, and when they attacked, Gu Fengchun could transform into a spiritual body at any time, and between the spiritual body and the spiritual body, there was only a confrontation of spiritual power, even if they won, it would be useless at all. Because it is not the ancient style in the material state, it is of no use to them.

Gu Fengchun naturally knew this, but he also knew that this was not the best moment to transform into a spiritual body, and the spiritual body would not be able to enter this small door. Otherwise, prehistoric humans would have destroyed the devices inside that were not good for them. He chose to resist hard, so the process was painful.

The spiritual attack of prehistoric humans is to make people feel severe pain, and then when they are distracted, they can take advantage of the weakness. Of course, to deal with Gu Fengchun, this set of procedures is simple to say, but it is not so easy to do. Prehistoric humans were also well aware, although Gu Fengchun had promised them. You can agree to the conditions of prehistoric humans, but prehistoric humans who have lived for countless years know better that only themselves are truly reliable! Believing Gu Fengchun's words, it was a very unreliable thing, so they planned to use the void created by the immortal medicine to seize Gu Fengchun's body at the beginning, and at this point!
