With Alwyn planning accordingly, the members of the Survey Corps avoided the giants who were attracted by the giantess's roar.

Eventually, the Survey Corps ended the off-wall investigation.

This extramural investigation is said to be the heaviest loss of the Survey Corps in recent years, due to the deliberate attack of the giantess Ani, almost a third of the members of the Survey Corps have been lost.

Of course, in the case of heavy losses, the harvest is also gratifying, the giantess's main body, Ani Leonard, has been captured alive, although the crystals sealed on her surface are very troublesome, but these are not things that the Survey Corps should consider.

At night, Sikong Xu, who returned to the Survey Corps headquarters in Ruth's Wall, was lying quietly in bed, thinking about the next series of problems he would face, the most important of which was the issue of the contract Mikasa.

The mood is a little irritable, and in order to relieve his emotions, he is trying to play with a special ability attached to the engraving.

A thirty-centimeter-long short knife disappeared out of thin air in his hand and suddenly appeared, this is a weapon made by Sikong Xu's technical class.

Probably to facilitate the students' experience, the school's engraving to the students seems to have many auxiliary functions, querying the current basic information of the students is one, querying the task is also one, and the independent cubic meter storage space is another.

As long as the student's mind moves, he can store the non-living matter that does not exceed the storage range of this space, and then take it out, and the "Detonation Talisman" obtained by Sikong Xu before is stored in this space until it is taken out and used, and even the bottle of "Junior Giant Blood Elixir" is also stored in it.

At this time, Sikong Xu was constantly putting the short knife in his hand into this independent storage space, and constantly taking it out.

"It's amazing." Sikong Xu sighed, although he had long known in his memory that there were many mysterious powers in this world in addition to technology, such as magic, superpowers, skills and so on, Sikong Xu was still shocked.

After all, he had just crossed over, and it would take some time to accept this world as a matter of course.

Sikong Xu had not had time to be idle before, but now that he finally relaxed, Sikong Xu finally fully understood the auxiliary function of this mysterious mark on the back of his hand.

Gradually, Sikongxu's heart has calmed down.

Due to his very good luck and the fact that the sacrifices were good, Sikong Xu used his first talent skill, "Dimensional Summoning Technique", to summon the perverted ability of "Infinite Martial Arts" for the first time.

It is precisely because of this ability that Sikong Xu has completely changed his appearance, and the strength evaluation on the engraving has not only been directly promoted from "undecidable" to "ink black primary", but Sikong Xu has also obtained a large number of credits, with these credits, Sikong Xu's strength will definitely be enhanced again after returning to the academy.

Just your first innate skill has given you so many benefits, so what about your second innate skill? I really don't know what my predecessor thought, with such a natural skill against the sky, it would be treated as a waste.

Sikong Xu thought secretly, as everyone knows, Sikong Xu was able to summon the ability to defy the heavens like "Infinite Martial Refining" this time, and most of the credit was due to the solid piece similar to crystal that Jiang Hong gave him.

The higher the level of the sacrificial item, the higher the level of the summoned object summoned, it seems that the thing Jiang Hong gave is really not an ordinary thing.

"Contract Summoning...... Whether you succeed or not, you have to give it a try......"

The goal of Sikong Xu's second talent skill is naturally Mikasa, as long as Mikasa agrees, then the two "beings" of Sikong Xu and Mikasa can be connected forever, so that after returning to the real world, Sikong Xu can also summon Mikasa.

Judging from Mikasa's current favorability of himself, the relationship between the two parties is only about confessing and accepting this last step, so the probability of success is still very high.

After all, Mikasa's concern is himself, and at most he can barely add an Allen.

However, Sikong Xu's feelings for Eren did not reach the point where he couldn't live without the other party in the original book, and in Mikasa's eyes, Eren may be like a younger brother.

Hehe, it seems that Goddess Mikasa can't escape her palm, haha!

In this way, Sikong Xu came to the next day with excitement......

Early the next morning, Sikong Xu took Mikasa to his room and confessed everything......

"That's all I want to say, Mikasa...... You...... Agree with me...... Contract?" Although the "Infinite Martial Arts" had strengthened Sikong Xu's state of mind to the point of perfection, to this day, Sikong Xu's heart was still trembling.

After listening to Sikong Xu's fantastical confession, Mikasa, who has always been indifferent, couldn't help but show an exaggerated look of surprise.

"You're saying you traveled from another world to complete a series of missions?"

"That's right......" Looking at Mikasa's expressionless pretty face, Sikong Xu smiled bitterly.

"You want me to go to that world with you, so you need me to sign a contract with you?"

"That's the ......," Si Kongxu's smile was a little bitter.

"So...... The one I've known since I was a child...... Is that you?" Mikasa finally said the question she wanted to ask the most, and Rao couldn't help but tremble when she spoke with her character.

It seems that Mikasa is really afraid that Sikong Xu will say the word "no......

Sikong Xu is about to cry, and Mikasa's problem is something he himself wants to figure out!

I can't help it...... I can only follow the feeling in my heart...... Let's hope you can't go wrong......

Sikong Xu took a deep breath, and then said, "It's me." ”

In an instant, Mikasa's beautiful face immediately bloomed with a peerless smile.

"Thread...... I'll go with you......" is a simple sentence, and the meaning contained in it can only be felt after Sikong Xu.

When a girl is able to give up everything in the world for you, that girl must ...... Treasure!

Sikong Xu also laughed, to be honest, although he had all the memories of getting along with Mikasa before the crossing, but whether the "self" in that memory was true or not, Sikong Xu couldn't be sure, but he faintly felt in his heart that the "self" in his memory was himself.

"Such a strange phenomenon has never happened to other students, it seems that I have to ask the head teacher what is going on when I go back." Sikong Xu muttered.

"What's wrong, Xu?" Seeing Sikong talking to himself, Mikasa asked softly.

"Oh, it's okay, Mikasa, let's make a contract now."

"Hmm."

Sikong Xu looked directly at Mikasa's bright eyes, and then, he immersed his spirit into the depths of his soul.

Entering this gray place again, Sikong Xu no longer felt strange, and then, through his own spirit, he saw two mysterious and mysterious patterns that existed here.

An outermost circle with countless dazzling thin lines and rectangles outlined inside, this is Sikong Xu's first natural skill, "Dimensional Summoning".

However, now Sikong Xu can't use this skill, for no other reason, this skill is still in a cooldown state for half a month.

Sikong Xu found that he had been in the world of "Attack on Titan" for almost half a month, but this skill was still on cooldown, and it seems that the cooldown time of half a month refers to half a month in the real world.

Immediately after, Sikong Xu locked his spirit directly onto the second pattern.

This pattern also appears to be circular, but this circle is very different from the circle of the "Dimensional Summoning" talent.

The circle represented by "Dimensional Summoning" is outlined by a straight line, but the circle of "Contract Summoning" is outlined by countless tiny characters.

For these characters, Sikong Xu said that he couldn't understand them either.

Inside the circle outlined by its characters, there are also countless lines and rectangles carved into the pattern, but in the very center there is a five-pointed star.

Contract Summoning, On!
