My bathroom leads to the celestial realm.

108 Thunder Talisman Array Plate

Inside the cave, Xu Yan, riding the smoke and shadow, became one with his sword, like a wisp of smoke passing through the portal and returning to the present world.

As soon as they passed through the light gate, they immediately felt a great difference. The range of their divine sense was greatly compressed, barely extending more than ten zhang, or thirty meters.

The true essence was also greatly compressed; if it was originally a great river, it could now only be considered a slightly larger stream.

Fortunately, the quality remained unchanged.

Xu Yan had a slight toothache. If he had known that the compression of true essence in the mortal world was so effective, he would have come back to break through again.

Of course, he was just making a casual comment. Without spiritual energy to support him in the modern world, how could he break through?

He moved his arms and secretly wondered: I wonder if it suppresses the physical body, but the strength should not be much different, right?

The monitoring equipment emitted a piercing beep. Li Er scrambled out of the bathroom and immediately spotted Xu Yan's back: "Little Xu? Didn't you say you were going into seclusion to break through to the Foundation Establishment stage? Did you succeed?"

Xu Yan turned around and smiled: "It's done!"

"Hey!" Li Er couldn't help but look you up and down. "It's only been a little over a month... sigh, look at my memory, it's been more than half a year over there, hasn't it? You've returned home in glory!"

Xu Yan laughed even harder: "Where's my master?"

"He's at the bureau," Li Er said. "He's been busy lately and hasn't been back for several days."

"What are you busy with?" Xu Yan asked curiously.

"Hey, what else could I be busy with? Spiritual energy conversion, of course!"

Xu Yan was quite surprised: "There's progress?"

That's only been a month or so, that's quite fast!

One hour later, at the Special Security Bureau's experimental center.

Hundreds of jade talismans are arranged in a staggered pattern on a formation plate that is just over a meter in diameter. At first glance, it looks a bit like a miniature tunnel boring machine.

Several thick cables were connected to the complex experimental setup. Xu Yan looked at them from left to right, but still couldn't figure out what the equipment was for.

"Attention all units, experiment begins!"

Master Cheng's voice came through the walkie-talkie. The thunder talismans on the array plate were activated one by one, but unlike ordinary jade talismans, they did not immediately release all their energy. Instead, they were in a state of being about to be released.

Xu Yan didn't put much effort into refining talismans, but he knew that existing talisman arrays couldn't do this, so it was obvious that Master Cheng had made the corresponding improvements.

Each department reported their preparation status over the walkie-talkie, and with a command from Master Cheng, the circuit was connected.

The jade talisman immediately released an electric current, which entered the corresponding energy circuit. The counterweight placed on the guide rail immediately began to move. After moving about ten meters, the power was cut off and the counterweight stopped.

Exhilarating cheers immediately erupted in the laboratory.

Xu Yan asked curiously, "Did it work?"

Zhang San nodded repeatedly.

Xu Yan asked again, "Is this an electromagnetic cannon?"

"No." Zhang San shook his head again. "This is an electromagnetic sled, a kind of preliminary experimental device for an electromagnetic gun."

Xu Yan said "Oh," looking as if she suddenly understood.

Zhang San lowered his voice and said, "This technology has been tested many times and is already very mature. I heard that it has been approved by the higher-ups to build an experimental ship."

"Experimental ship?" Xu Yan's mind immediately conjured up images of various extremely futuristic ship designs.

Zhang San added, "Because it's a new technology, the ship isn't very big. If the experiment passes, it might be used on the next aircraft carrier."

Hey!

Xu Yan leaned back tactically: "Is the higher-ups being that aggressive?"

"The main reason is that this technology is so useful," Zhang San said with no small amount of pride. "It's small in size, discharges quickly, has high energy density, and greatly reduces the need for corresponding equipment."

As a member of the experimental team, he has every right to be proud.

Xu Yan didn't know exactly how big or heavy the equipment was, but he did know that every inch of space on a warship was precious, and the space and displacement saved could be converted into combat effectiveness.

He remembered his plan again, but it was still far from being finalized, so he refrained from telling anyone.

It's easy to say, but it's really inappropriate to set expectations and then fail to deliver.

He asked with considerable anticipation, "What about the electromagnetic railgun? Has it been tested yet? When can I get one?"

"Oh, this!" Zhang San scratched his forehead helplessly. "Theoretically, it's fine, but the experiment hasn't been done yet, so we'll have to wait a bit longer."

"I see!" Xu Yan couldn't hide her disappointment.

Although his cultivation level had improved, his enemies were also more difficult to deal with. Without a decisive weapon in hand, he couldn't feel at ease.

Zhang San quickly tried to salvage the situation: "Hey, we don't have an electromagnetic cannon, but we've prepared an electromagnetic rifle for you."

Xu Yan looked conflicted: "Can a gun be compared to a cannon?"

Zhang San was a little embarrassed: "It's not fair to compare, but it's better than nothing, right? Besides, we specially lengthened the barrel, so the muzzle velocity is faster and the power is greater."

"What's the caliber?"

"The smallest needle, the largest 12.7..."

Xu Yan was quite dissatisfied: "Couldn't the caliber be made larger? It should at least be 23 millimeters, right?"

Zhang San barely suppressed the urge to roll his eyes: "It's not that the bigger the caliber, the better. That sniper cannon we had before was .23 caliber, but those few stardust flying swords were less than 12.7 caliber!"

Xu Yan thought about it and felt a little better: "What about its power? It's higher than a sniper cannon, right?"

"Of course!" Zhang San said. "The muzzle velocity of a sniper cannon is less than a thousand, while an electromagnetic rifle can easily reach fourteen or fifteen thousand, and even more than two thousand in extreme conditions."

Before Xu Yan could speak, Master Cheng, dressed in a white coat, walked out of the laboratory: "Mo Ting, when are you coming back... Hey, you've reached Foundation Establishment?"

Xu Yan laughed without any restraint: "Just broke through."

"Excellent! Excellent!" Master Cheng was even more excited than if he had broken through himself. "Come, let's test it out and see how much you've improved!"

Xu Yan was speechless. How long had it been? His master had already learned to use data to speak?

"Master, can we wait a moment?"

"What are you waiting for?"

Xu Yan gestured to Zhang San: "Speaking of electromagnetic cannons, I need to get some better shells."

Master Cheng was astonished: "The Milky Way Star Sand isn't enough?"

Xu Yan chuckled awkwardly, "Almost there."

Master Cheng frankly said, "It's not that the Heavenly River Star Sand is bad, it's that my weapon-refining skills are lacking. You should take some time to go and see Brother He later."

"Isn't that a bad idea?" Xu Yan hesitated. "He's in seclusion, trying to break through to the Nascent Soul stage!"

"Then we'll go after we've finished our seclusion..." Master Cheng paused here, as if he wanted to say something but couldn't.

Xu Yan asked curiously, "What's wrong?"

Master Cheng hesitated for a moment, then said, "That Blood Demon Sword is much stronger than the Heavenly River Star Sand, it's just a pity to destroy it."

Xu Yan was completely flustered, but then she felt incredibly tempted: "That sword... will I be able to use it in the future? Won't there be any hidden dangers?"

"There's no real threat. Our Divine Firmament Sect isn't afraid of that. The key is your own cultivation level!"

"Then forget it. I finally got this sword after a lot of trouble. Wouldn't it be better to save it until I reach the Nascent Soul stage?"

Master Cheng said earnestly, "The sword is good, but it may not be suitable for you. You should hurry up and learn how to forge weapons and make one that suits you."
