The first thing Ethan did when he returned to Earth was to 'take' a part of his knowledge from the Book of Inheritance and give it to Tony Stark.

With these relatively advanced knowledge in the universe, Tony Stark was able to take all the techniques he mastered up a few notches.

Not to mention anything else, nanotechnology that will not appear until at least many years later is very likely to be tinkered with by Tony within a year or two, and those later models of warframes will be born ahead of schedule.

Because of Ethan's intervention, Tony Stark's steel armor has long deviated from its original development path.

According to the original plot, Tony should have just developed the Mark VII at this time, which was the one used during the New York War.

With a miniature missile launcher, thrusters installed on the back, etc., the Mark VII can only be regarded as an optimized version of the previous generations of Warframes, and there is no substantial improvement.

Since Ethan gave Tony a variety of magic stone techniques and gave more magic theories, Tony's steel armor has long deviated from its original development track, except for the initial creation of a separate set of magic armor, Tony has been combining these magic techniques into his own armor.

Now that he has mastered some magic stone technology and Asgard's more perfect energy-using technology, Tony can now completely create a powerful battle armor that combines science and magic, and then fuse some nanotechnology, so the problem of carrying has also been solved.

Iron Man is no longer the Iron Man that Ethan was familiar with in his previous life.

Ethan didn't care, he cared if Tony could better use these techniques on his new boat. After giving him enough knowledge for him to digest slowly, Ethan also left the Cosmic Cube for Tony to study.

This is a tacit agreement they reached before, and after Ethan brings back the Cosmic Rubik's Cube, Tony can study it for a while.

He used to worry about S.H.I.E.L.D. or Hydra, stealing things from Tony wouldn't be easy to handle, but now Ethan doesn't worry about that happening at all.

Not to mention the defensive strength of Tony's laboratory today (magic stone technology, various black technologies, Jarvis's full monitoring and various magic alarms arranged by Ethan. Even if the Hydra man did steal it, Ethan would be able to retrieve the Rubik's Cube in a matter of seconds.

"I'm studying these things, what are you going to do?"

Tony was very happy when he got the toy he wanted, but he was a little unhappy that Ethan refused to help him with his research for the next period of time, in his opinion, aren't mages a bunch of research maniacs?

"I'm going to do something important. ”

"Don't tell me you've suddenly come to faith in God. ”

Ethan not only 'transferred' some knowledge of Asgard to Tony during this time, but also did some of his own things, plus borrowed Harpy Hogan with Tony, which is Tony Stark's funny driver and bodyguard, so Tony knows where Ethan is going.

"Don't tell me you're looking for churches everywhere and you want to get married. When Tony said this, he suddenly felt that he had guessed the truth: "You are not really going to get married, are you?"

Ethan didn't have a chance to interject from beginning to end, and could only wave his hand with black lines on his face to indicate that it wasn't what you thought: "I just need to make some props, I need to collect something." ”

"What will be in the church?" Tony thought about it, but couldn't think of anything worth thinking about there, so he simply shook the tools in his hand, picked up his coat and prepared to go with Ethan: "I'll go and see it too, I'm curious about what you're going to do." ”

"Okay!" Ethan spread his hands, he didn't care about Tony, as long as Tony didn't mess with him, "But I'll warn you, this journey is boring and boring." ”

Tony didn't believe it, and he resolutely followed Ethan out of Stark Tower, and then led the way by Harpy to the most popular church in the neighborhood.

As for whether it was a Catholic church or a Protestant church, Ethan didn't care at all, he asked Harpy to help him collect the locations of all the churches in the vicinity, and then made a route according to the distance of the location, and the one in front of him would be the first stop.

Once inside the church, Ethan didn't run around, he wouldn't do anything strange in a place like this.

He just quietly sat down in an inconspicuous position, and then took a cross from his coat pocket.

Tony stayed next to Ethan, watching him sit quietly, take out a cross and hold it in both hands, and begin to close his eyes and pray—at least it seems.

"You can't really come here to pray, do you?"

Tony's voice was a little louder, but he soon realized that this was not a place to speak loudly at will, and even he didn't dare to offend the believers and God's servants, so he made an apologetic gesture to the other people in the church and lowered his voice to ask Ethan.

"What the hell are you doing here? If you don't tell me, I'll tell the priest here out loud that you came to the Catholic church with a Protestant cross to pray......"

“......”

Ethan believed that this thing was absolutely dry, so he lowered his voice and simply explained some of his actions.

"Churches, places where prayers are often held by large numbers of believers, tend to gather the beliefs of many people, which are not ethereal, and even for some gods, these beliefs are the basis of their existence. ”

Tony was a little confused, although he didn't understand the theory very well, but he also understood what Ethan was thinking.

"Are you trying to collect these beliefs? What are you going to do? Are you going to make yourself a god?"

Ethan glanced at Tony, remembering that this guy was not a mage with a formal magical education, and he didn't know how lethal this power of the believers' wishes and beliefs could be to a mage, and even the most crazy mage would not dare to use this power as his own magic.

"No, just collect it, after all, belief is also an energy. ”

In layman's terms, it is to collect the power of faith or the power of will, this power has many problems in his eyes, such as too many impurities, which will affect people's spirit, even if the gods have accepted the wishes of believers for a long time, they will be unconsciously affected by this power to their own character.

But no matter how many shortcomings there are, we can't ignore that this kind of energy exists in almost all civilized worlds, and as long as you have the right means, it is almost the easiest energy to obtain.

Ethan obtained the relevant knowledge from Colybuso, combined with some knowledge from Merlin's Book of Inheritance, and finally relied on some of the knowledge he saw from Asgard to finally have the ability to collect this energy and use it for his own use.

The cross on his hand was made at Tony's during this time. The material is not special, it can even be said to be ordinary, but the technology contained in it can be said to be the crystallization of Ethan's current knowledge.

Through this humble cross, Ethan can absorb the ethereal power of faith, and remove the impurities in it as much as possible to reduce the negative effects of its existence, and finally transform it into an energy that can be used by him.

Considering that this energy will inevitably be affected by the huge willpower of its own characteristics, and the transformed energy also needs to fit these beliefs themselves, otherwise a large amount of willpower will be wasted. Ethan experimented a few times and found that the Light Energy was the best option.

Unfortunately, Ethan has not been exposed to the true Light, and it is not clear how to transform it. If he had mastered the true Light, the impurities would not be a problem, and the chaotic beliefs would have been completely purified or assimilated by the Light.

Ethan could only choose to extrapolate backwards based on the energy of the Death Stone, plus the energy similar to the Holy Light that he finally created based on his own understanding.

In the final test, he was surprised to find that after incorporating a certain amount of wishing power, this energy became closer to the holy light in his impression, the energy was full of life, blazing, pure and other characteristics, and the restraint effect on negative energy was also more than before, and it can even be said that now this newly born energy is more worthy of being called holy light than before.

The name of the cross he made this time was also named the Holy Light Cross.

"So you asked Happi to inquire about all the churches in the neighborhood that are more crowded, and to collect the power of faith one by one, and then transform it into holy light and store it in this cross?"

After listening to Ethan's explanation, Tony finally understood what Ethan was doing, and he was very amazed by this, he didn't expect magic to work like this?

"That's ......"

"Isn't this kind of collection particularly time-consuming?" Tony found himself talking to Ethan for a while, who never changed his movements, still maintaining a 'prayer' posture.

"It's not that easy to collect wishing power, I have to constantly coordinate my mental power, and I also want to avoid any abnormalities when transforming. ”

Ethan could only maintain this posture when collecting the wish power, and he found that this posture and the mental fluctuations similar to prayer made the wish power in the church more easily attracted to him, but even the speed of collecting still made him want to cry, and he estimated that if the church he circled did not have a few months, it would be impossible to complete it all.

Affirming that Ethan would only be able to stay in this position for a short time, Tony decisively lost interest, smiled and patted him on the shoulder, and then asked Harpy to send him back to Stark Tower.

He would rather go back to his lab and wander around than sit in the church like a fool with Ethan, even if it was more fun to build a mad robot trying to destroy the world than to watch Ethan be here in a daze.

Killing Tony wouldn't have believed that Ethan would actually pray to God.
