Of course, the difficulty of the two radio communication devices is not at the same level. At least the core component of the latter, the electronic tube, is still being trial-produced by the engineering department.

And the failed works have been piled up into a small hill outside the laboratory.

As for Edith's suggestion to modify the Skyfire in the report, Roland was quite tempted. On a technical level, it is not difficult to transplant a 35mm sniper cannon onto a biplane, as long as the entire gun body is buried directly below the belly of the aircraft and the shooter's seat is removed. If the number of rounds carried is controlled within ten, it can be roughly balanced in terms of weight, and there is no need to modify anything else.

The only problem is that in order to obtain large-sized magic stone bullets, witch or demon blood must be used to dissolve and separate the magic stone veins until a suitable volume and shape of God's Punishment Stone is obtained before further processing can be carried out. If it is too large, the existing knives and lathes can hardly do anything with it, and if it is too small, the magic stone will appear too brittle. The process of screening the base material requires a lot of magic power blood, even if the Witch Union and the Sleeping Spell support his approach, that little amount cannot meet the needs of the war.

If you want to truly solve this problem, you still have to find a way from the demons.

Either figure out why they can process large magic stone pillars.

Or use their blood to make it.

Now the Skyfire can return to Neverwinter from the front line in one day, and with Agatha's refrigeration ability, it seems possible to transport fresh demon blood directly from the battlefield?

Roland silently recorded the proposal on the agenda.

…

After nightfall, he entered the dream world as usual.

In order to speed up the progress of the Graycastle Design Bureau's project, Roland has greatly increased the number of times he enters the dream in the past month. This has made the dream world, which was originally behind the real world in time, catch up a lot. The city, which was still in late summer and early autumn, is now fluttering with snowflakes, as if it is just a different area of the same world as the outside.

The morning in the Tongzilou community is still busy. The expansion of the Erosion and the destruction of Prism City have not brought any impact to the residents. The breakfast stalls on both sides of the streets are still shouting endlessly, and people hurry through it. The white snow accumulated overnight is already covered with footprints.

Although Lan said that this world is also facing a War of Divine Will, it is undoubtedly much more peaceful here than the Wolfheart battlefield filled with red mist.

In addition, the long-term entry into the dream brings not only the change of seasons, but also the change in the mentality of the demon traverser.

After a period of surveillance and observation, Roland can basically confirm that the demon who calls himself Vakiris is not a native of the Kagkad Peninsula. Although after checking the registration information repaired by the Martial Artists Association, there is indeed such a person in the visiting group from the peninsula, her behavior is difficult to explain by common sense.

Roland is no stranger to this phenomenon of authentic identity but internal changes, because he himself is an example. It is undoubtedly the most appropriate to describe the other party as a "transverser".

At the beginning, Vakiris could still maintain her disguise, or try to act like an ordinary martial artist, such as reading various books and not speaking if she could, but as time went on, she gradually became impatient.

Especially after her injury healed, she secretly sneaked into the depths of the forbidden Prism City, standing in front of the Erosion rift and staring silently. According to Tongen's report, Vakiris showed an obvious look of anxiety on her face at the time, as if she was craving for something. She even thought several times that the other party was going to jump into the Erosion, but she finally endured it.

If this was to mourn the passing of her partners, it would be too far-fetched, because Vakiris did not stop even half a step at the place where the visiting group was killed – she came straight for the Erosion from the beginning.

If you think in her shoes, it is not difficult to understand the change in her mentality.

Coming from the demon city to this completely unfamiliar modern city, she may be able to hold her breath at first, wanting to figure out where exactly this is, but as time drags on and the hope of returning is still slim, anxiety can be said to be inevitable. Perhaps the real reason Vakiris sneaked into Prism City was to see if she could return to the world she was familiar with from the rift where she came.

Unfortunately, the memory fragments did not fulfill her wish.

In any case, it is extremely difficult to disguise to this point, after all, Vakiris does not know that all her actions are in Tongen's eyes. If it were not for these details revealed in private, looking only at her interaction with other martial artists, it could almost be said to be flawless.

Roland asked himself that if he were in her place, he would definitely not be able to do this.

Now that her identity has been confirmed, the next step is how to deal with it.

At this moment, a text message came from the phone.

It was Phyllis.

"Your Majesty, everyone is ready."

Roland put the phone in his pocket and got up and walked into the living room.

Jiero was busy putting the egg noodles on the dining table. Seeing Roland appear, she put her hands on her hips and said, "Uncle, you haven't forgotten what you promised me, have you?"

"What, did you get up so early because you were afraid I would sneak away?"

"It's not the first time you've done that." She pouted.

"Don't worry, I definitely won't this time." Roland smiled and walked over and touched her head, "Let's have breakfast first. After we finish eating, we'll go next door and call Garcia and then set off together."

The most eye-catching event this winter, besides the New Year, is the Martial Arts Tournament, which is held every four years. For junior and senior high school students throughout the city, if anyone can go to the venue to watch it, they will definitely become the center of attention. Jiero, who was originally not very interested in this type of competition, was not immune. After begging in every possible way, Roland had no choice but to agree to take her to the venue to experience it up close after the school's winter vacation.

Considering that the Enforcer is in charge of the competition today, and it is the round-robin stage, the possibility of a Fallen Demon appearing is not high. Besides, Jiero has to return to her hometown during every long holiday. As the little girl's "only request", he really couldn't refuse. What's more, with her dragging Garcia, it would be more convenient for him to act.

Roland decided to face the demon traverser directly.

*******************

This is the fourth month.

Vakiris seemed to be watching the bustling arena intently, but her mind was not on it at all.

Four months have given it a basic understanding of this world, and also made it aware of the various inheritances of mankind. In a sense, it itself has become a member of accepting the inheritance. As long as it can return to reality, it will surely benefit the race a lot – however, the most fatal problem is that it has never been able to find a way to leave the consciousness world.

Vakiris has a lot of important information, but it is suffering from no one to convey it, just like it finally found a bottle of spring water in the desert, only to find that the bottle mouth was sealed.

Whether it is sending a rescue request to Hequezord or trying to sense the trace of the King, it cannot get any response. Even when standing in the rift in that field and meditating, the consciousness world does not respond to its call – it has never encountered such a situation before.

Vakiris couldn't help but hate the Lord of the Celestial Sphere.

Why doesn't it try to wake itself up at this time?
