It is necessary to sign a cooperation agreement, because the cooperation agreement can form restrictions and constraints on both parties. When such restrictions and constraints are formed, there will be no casual breach of contract. Once a casual breach of contract occurs, it will be punished.


    This is very similar to the soul contract.


    Of course, there are many differences.


    For example, the restriction of the soul contract on both parties will be more serious. To be exact, it is the party who takes the oath against each other. The restriction is extremely severe. After taking the oath, it will often form a strong constraint. It can only obey the master''s orders and can''t produce the idea of betrayal. Once you want to betray the master, you will be subject to disastrous punishment.


    People who sign a soul contract with Lin Feng will be subject to such constraints, but this soul contract will not have any bad impact on Lin Feng.


    The cooperation agreement is two-sided, because both Lin Feng and Taixu Shenjia need to add their own names to this agreement, and they will naturally be bound by this agreement.


    However, even if they are bound, as long as they act according to the contents of the agreement, they will not encounter any trouble in the next hundred years.


    Lin Feng and Taixu Shenjia had a good discussion on the content of the agreement.


    The content of the agreement includes what rights and obligations both parties have, what types of things they have, the right to refuse to do, and so on.


    Lin Feng and Taixu Shenjia are quite satisfied with this agreement. After signing the agreement, Taixu Shenjia asks Lin Feng if there is a place to close, and it needs to close.


    Lin Feng has some regrets. He has been closed for so long and still wants to close. He is really a Madman of cultivation.


    The hidden meaning of the closed place asked by Taixu Shenjia is naturally to ask Lin Feng if he has space to carry with him.


    The space that Lin Feng carries with him has a big world and time space. Lin Feng will not easily expose time and space to others, not even Taixu Shenjia. He will not let Taixu Shenjia enter time and space. There is no problem in the big world.


    Lin Feng said, "I have a big portable world and can send you into it for closed practice!".


    "That would be great!". Taixu Shenjia said.


    Before entering the big world, Taixu Shenjia dug out the grass together with some soil. Although these grass are very common, they are of great significance to it.


    Every year, the grass will wither, die, and then to new life. It has been an extremely long time.


    For it, it is more like a beautiful sustenance.


    Lin Feng sent Taixu Shenjia and these grass into his big world.


    The matter of Taixu Shenjia was finally solved perfectly.


    Because he has to go to the world behind the scenes to rescue Mr. turtle after a while, although Lin Feng''s strength has been greatly improved, what is the world behind the scenes?


    That''s the base camp of the behind the scenes.


    As one of the four universes, the destruction of Kyushu universe one era after another is made by the behind the scenes world. It can be imagined how terrible the behind the scenes world is.


    Moreover, in their own world, the strong behind the scenes will be blessed by the power of the world, far more than the strength outside.


    Therefore, going to the world behind the scenes to save people is actually a very dangerous thing, but it is different with Taixu divine armor.


    With the Taixu divine armor, you really meet the strong man at the creator level who is the master of the world behind the scenes. Even if the strong man at the creator level gets the bonus of the world behind the scenes, the combat power is terrible to the extent of heaven.


    However, the perfect integration of Lin Feng and Taixu Shenjia can at least be invincible.


    At that time, it will be much easier to get rid of the danger.


    Therefore, with all the means Lin Feng has mastered, he can actually try to go to the world behind the scenes to rescue the turtle Lord. However, there are still some things in the wasteland world that have not been handled.


    Lin Feng needs to wait until the things in the waste land world are almost handled, and then go to the world behind the scenes. Things always have to be done one by one. If the order is out of order, some troublesome things may appear later, which is not very good.


    Lin Feng and others did not continue to stay on the moon. There was nothing else in such a desolate place. It was of little significance to stay here.


    Lin Feng and them left the moon and came to the island. The dust-free island was completely broken down, and everywhere exuded an atmosphere of decay and death.


    What a prosperous place it used to be, but now it has become like this, which makes people sigh with emotion.


    Probably because he wanted to leave, the clean sky also became a little sad. Although there was a resentment between him and his family, no matter what kind of gratitude and resentment they had, they all flowed the same blood and could always be resolved. Now, he doesn''t even know whether the dozens of people who escaped from his family are spreading branches and leaves outside, Let their family pass on, whether they can pass on to the present.


    Everything is unknown.


    In fact, Lin Feng can understand the sad things in the heart of the dust-free sky. Blood and family will eventually become the weakness in everyone''s heart. Even the most vicious people have a corner to give blood and family in their heart.


    Can''t give up easily.


    Lin Feng didn''t bother the dust-free day. The last memory of the dust-free island and the dust-free family is about to leave here. His mood is complex and sad. It''s normal. Let him calm down.


    Half an hour later, Lin Feng and others left the dust-free island and returned to the real world. They were still in the sea. They entered the ancient ship Xuanyuan in the starry sky.


    Calculate the time. It is estimated that the leading troops of Longteng Pavilion should have arrived at the west sea world, right?


    Lin Feng needs to see them.


    Conquering the sea area starts from completely controlling the west sea world.


    The ancient ship Xuanyuan quickly flew towards tianmeteorite island. When returning to tianmeteorite Island, Lin Feng entered the big world and communicated with Taixu Shenjia. In the future, they will have a lot of cooperation. Since they want to cooperate, they naturally need to know and understand each other.


    They need to try to fit. Only after fitting can they know more clearly how to cooperate with each other perfectly.


    If Lin Feng wears Taixu divine armor, but he cannot form a good fit with Taixu divine armor, his own defense will be greatly improved.


    However, their own strength may be limited, which should be paid special attention to.
