"So, this thing is the yellow explosive you call it?" Carolon asked, looking up at the yellow granular object in the glass jar.

"That's right, this is it. Murphy nodded, picked up the bottle containing the yellow explosives and shook it, "It's very stable, don't talk about dropping it or stepping on it, even if you burn it with fire, it will only burn silently, it's the most ideal, explosives for construction." ”

"If it's stable, how can you detonate it?" said Rochebus.

"That's where Carolin's help comes in, and there are two ways to detonate this explosive, but one of them is not available yet.

"We need Master Carolon to release the arc to detonate it, and we can make a mini-circle here that is convenient for ordinary soldiers and workers. ”

Murphy had already thought of all the conditions that might limit the appearance and use of explosives, and came up with a solution.

"Am I here again?" said Carolen's illusionary image, furrowed his eyebrows, and there was some displeasure between his words.

Every day, I have to make all kinds of machines, enchant everything that needs to be enchanted, I have to delve into new knowledge, and now I have to carve a magic circle for him, even if he is an undead who never has to rest, time is too busy!

"Actually, I think I can make a machine to carve formations instead of me painting this kind of low-level magic circle, I don't want to waste my precious time on these little things. Carolon sat down on the chaise longue and spread out on the chaise longue very naturally.

"By the way, there are also enchantment machines, and I also hate drawing those low-level enchantments, it's a real waste of time. As soon as Carolon lay down, she slapped her chair and attached her hand, emphasizing another thing again.

In fact, Carolon had already told Murphy more than once about these two things, but Murphy and Ben couldn't solve them.

After all, if you spend money to hire enchanters or array mages to do these things, even if these noble mages accept a fixed salary type of employment, the salary will reach the price of fifty gold naso per month, and the labor cost is extremely high.

It's just that Murphy only has one idea in mind about making formation machines and enchantment machines, and he doesn't even have the first version of the design draft.

"I'll try to conceive it. Murphy nodded in agreement.

But then again, if the enchantment machine and the formation machine are made, it may be able to replace the industrial mother machine, after all, that thing Murphy can't make.

"By the way, Mr. Rochebus, how did you get this solution?" Murphy asked Rochebus, gesturing to the toluene on the table.

"Oh, I extracted this thing from the tar in the coking room of the Chengdong Coal Mine, and I didn't know what it was for at the time, so I planned to take it back for experiments, but I didn't wait to use it, so you used it. ”

"This thing is called toluene, and it is one of the indispensable materials for making explosives, and the extraction of toluene will be left to Mr. Murphy bowed to Rochebus, his discovery deserved Murphy's treatment of him.

"Your Highness has tormented me, this is the duty of my subordinates. Luo Che Bass hurriedly picked up Murphy and said respectfully.

"But for now, let's test the performance of this explosive," Murphy said, gesturing to the yellow TNT in the jar.

"Give it a dosage to me, and I'll add an arc circle to it. Carolon got up from her recliner and was about to walk out.

Two hours later, the newly planned test site in the west of the city was located.

"Your Highness, we have arrived. Philip's voice came from outside the carriage, waking up a dizzy Murphy in the city.

"We're here?" Murphy opened his eyes in a daze, shaking his head to sober himself up, "What about Arthas?"

"Your Excellency, they're still on their way, and they'll be there soon. ”

Opening the car window and looking at the muddy dirt road that had gradually melted and the originally hard dirt mixed together, Murphy frowned, the road problem in this era is a pain!

They also blame themselves for always focusing on the development of military science and technology and ignoring the people's livelihood, but they have not made more important cement.

"Anyway, I just sold the gun, and now I have money, isn't it easy to build a few roads?" Murphy thought, already deciding on the next direction of development.

Push the door and get out of the carriage, and in the two carriages in the back, Carolon and Cartbus Bass also pushed the door and walked out.

"Where's what I brought? ”

Murphy whispered to one of his attendants.

The attendant answered, and hurriedly ran to the carriage at the end of the line, took several large packages, and placed them in front of Murphy in turn.

The two Carolins came up and stood behind Murphy, and Arthas, Marshall, and Bruno had just arrived.

"Now, I'm going to show you the latest results of the Remlos Fort Science Laboratory!" Murphy happily slapped the yellow explosives on the table.

Everyone showed a look of interest, and every time His Royal Highness the Prince announced a new invention, it would surprise everyone.

"This is ten kilograms of black powder. Murphy gestured to the leather bag on his left.

"This is ten kilograms of yellow explosives. He patted the leather bag on his right again.

"I'm going to test these two types of gunpowder separately to give you the most intuitive feeling. ”

Murphy said, picking up the black powder and walking towards the pile of stones in the middle of the test field.

This test site is newly demarcated, and it is a place dedicated to testing new inventions, and the farmers and hunters within a radius of ten miles have been dismissed, and basically no one will be hurt.

The latest explosives test is placed here, and the middle pile of rocks is also used to make a comparison, so that people can directly feel the power of these explosives.

Walking to the nearest pile of stones, Murphy gently placed the black powder explosive bag in the stone, reserving the place of the fuse, which extended along the crack in the stone.

The fuse is more than forty meters long, and in order not to get wet by the muddy ground, Murphy also deliberately added a small "dry" enchantment to the fuse.

The finger ignited a flame and lit the fuse, which had been soaked in salt water, burned rapidly, but it burned out in just a dozen seconds.

"Boom!"

Although the power of black powder is not too great, it is also a high-explosive and high-burning substance, and a pillar of smoke rose from the pile of stones in the distance, and half of the pile of stones was blown away.

"Not bad, this is almost as powerful as a beginner fireball technique of mine. Carolon nodded, acknowledging the explosive power of the black powder.

"It's not over yet, this is our protagonist today. Murphy patted the other package in his hand.

The TNT explosives that had just been prepared were steamed by Murphy with water and cut into a square shape, which really looked like a plastic bomb on Earth.

Murphy looked at the TNT explosives in his hand, its outer packaging was a layer of lizard beast skin, sealed tightly and very tough, and in the corner of the explosive bag there was also a composite magic circle combining arc and remote control, which looked like it was from the handwriting of Carolen, a major formation event.

Murphy held the ten kilograms of TNT and placed it in the middle of the test site, and then quickly retreated a hundred meters away, propping up a magic shield.

Seeing this, the others also turned on their fighting qi and hid far away.

Seeing how good everyone was, Murphy activated the remote control circle in his hand.

"Boom !!".

With an earth-shattering explosion, Murphy felt the whole earth tremble, and a huge mushroom cloud rose from the pile of stones in the distance, and the shock wave bulldozed three huge stone piles nearby, and the small pieces of broken stone that burst were swept into the mushroom cloud, and were burned by the flames in the cloud and then thrown into the distance, and several pieces smashed on Murphy's magic shield, and the shield suddenly emitted ripples.

The sky-high flames simply pierced people's eyes.
