"Wait! You say that mines will automatically detonate at a distance of 20 yards? Jack caught the gist from Roland's narration and couldn't help but widen his eyes in surprise, "You really don't need to hit a mine directly to explode?" ”

Kafta nodded, and replied for Roland: "That's right, the mines on the Giant Demon Island are equipped with automatic triggering devices, and after the war, Mr. Sukhoi fished for the kind of mine dismantling research, which seems to be blessed with some kind of automatic triggering spell......"

"It's actually quite simple, it's a 'magic alarm'. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info" Roland smiled and unveiled the mystery, "Ordinary mine blessing this 1-ring spell becomes a magic mine that can automatically sense hostile targets at a certain distance, and automatically explode before the hostile target approaches, think about it, what if we use this idea on anti-aircraft artillery?" ”

"We will get a more efficient anti-aircraft weapon!" Jack excitedly calculated, "There is an additional cost to enchant the cannonball, but fortunately, the enchantment price of the 1-ring spell is not expensive, and the enchanted cannonball can kill and injure the enemy within a radius of twenty yards, and the efficiency is at least fifty times higher than that of ordinary cannonballs, which is more cost-effective when calculated comprehensively, which is perfect!" ”

"That's a great idea! And it is not very difficult to process this enchanted cannonball, we can connect the 'magic alarm' to an ordinary fuse filled with thunderstone powder, when the 'magic alarm' is triggered, the sharp alarm will cause a strong vibration, and then detonate the thunderstone powder, and the high temperature and high pressure generated will finally detonate the alchemical powder filled in the warhead. Kafta briefly sorted out the design idea of the "magic guide proximity fuse", and then couldn't help but admire, "We didn't even think of such a simple method before, it's so stupid!" ”

"It's not that we're stupid, it's that Mr. Roland has a very bright brain, and he always comes up with clever and simple ideas to solve seemingly complex problems." Jack said with a smile, "Only a mind like Mr. Roland can help me solve the technical problem of making fireball bombs, and can I associate them with artillery shells from mines and deduce a new way of thinking about preventing air raids." ”

Roland's face burned when he heard this. In fact, he is not as smart as Kafta and Jack think, and the reason why he always comes up with another way is because he has experienced modern technological civilization on Earth before crossing over, and when he encounters problems, he will naturally refer to the solutions that exist on Earth.

Putting down the glass, Roland looked at Jack and Kafta with a more solemn gaze.

"Both, I have a request that I hope you will comply."

"What are the requirements, please speak." Seeing that he suddenly became so serious, Kafta couldn't help but get nervous.

"The magic proximity fuze technology we just talked about has great military value, and I hope that you will keep it as secret as possible when developing and producing this device, so as to avoid leaking this technology."

When Jack and Tafka heard him say this, they also felt that the "magic guide proximity fuse" was indeed a vital military secret, and they solemnly swore to keep it a secret.

In fact, Roland knows very well that this technology cannot be kept secret for a long time, after all, the "magic alarm" is just a simple entry-level arcane, as long as you have the intention to imitate it, it is not difficult to do. He doesn't expect to monopolize this technology forever, the so-called "technological advantage" always starts with a certain space and time interval, and the magic guide proximity fuse is no exception, as long as this technology is exclusive to the Kolas Army for a certain period of time in the future, and it can make up for the lack of anti-air power, as for the enemy to be equipped with similar anti-aircraft weapons in the future, it can also develop a device to deceive the magic alarm for countermeasures...... In this way, military technology spirals upwards in a game of restraint and countermeasures, and there has never been — and never will — weapons that will never go out of style.

……

The complete failure of the counterattack cast a cloud of despair over Dragon City, and although the city's maze had been raised to the highest alert and the force field barrier was opened around the clock, the inhabitants of the city were not safe at all. Anyone who approaches the city gate, or climbs the city wall, through the force field enchantment, will see the coalition camp outside the city, the banners of the Kitland and Kolas coalition are fluttering, hundreds of cannons point to the north and south gates, the muzzle of the black hole is like the eyes of a demon, staring at the streets and alleys and residents in the city day and night, causing great psychological deterrence to the people who have suffered repeated defeats and trapped in the lonely city, and they dare not say it, and they all understand in their hearts that the fall of Dragon City is only a matter of time, Everyone who can't sleep at night has reason to worry about whether they will be able to see the sun tomorrow.

The atmosphere of decay spread like a plague in the city, so that even the generals who ruled the city on behalf of the dragon king were infected, and they felt more and more that the situation in the city had become uncontrollable, and that there was a shortage of supplies inside the city under siege by enemy troops, and this situation of chronic suicide would not change, and the coalition forces would not even need to attack the city in a major way, and the mob of the city that had been standing up for a long time would rise up and burn this majestic city that stood among the mountains.

The situation urgently needs to be changed, but how to change it is a thorny question - whether to continue the war or choose peace, and the top management of the "Dragon's Eye" is at loggerheads.

Andrea has now come to terms with the reality that any attempt to save Dragon City is doomed to futility, and that the only acceptable conditions for peace at the moment are predicated on Tamara's initiative: the army will board the Narokumu and the Skeleton Fleet and withdraw to the Twilight Valley, with a glimmer of hope for a comeback; Tens of thousands of civilians in Dragon City who could not be relocated were handed over to the Kitland-Kolas coalition in a peaceful manner in exchange for the coalition's leniency towards the city's inhabitants.

Jabella is the only half-dragon general who has never directly fought the coalition forces, and believes that she is not responsible for the defeat of the war, and her attitude is more tough, insisting that the "dragon's eye" is not yet at the end of the mountain, and that there is still a chance to fight a fateful counterattack, and Andreya's compromise is no different from surrender in her opinion, and must be resolutely opposed.

Yakov and Racine did not take a stand in the dispute between the two female generals, which was purely self-deprecating. In the "Dragon's Eye", the general's authority is mainly determined by the number of soldiers and horses under his command, and Yakov and Rahim's voice has been severely weakened by the loss of soldiers, although they agree with Andrea's suggestion more in their hearts, but they dare not speak publicly, otherwise the vitriolic Jabella will accuse them of being frightened by the coalition forces and losing the courage to fight again, so that they will not be able to step down.

Andrea's argument with Jabella seemed to go on forever until two unexpected events broke the deadlock.
