The guards quickly cleared the pit of the debris and then tested explosive No. 39. As a result, the test situation of No. 39 explosives was even worse than that of the previous No. 38, except for a muffled sound in the deep pit, and even the stone slab did not shake off.

Time passed bit by bit, and Li Gengyun saw that the number of explosives on the flatbed car was getting smaller and smaller, and soon there was the last explosive left, which was the fiftieth explosive. The results of the previous explosives experiments were very unsatisfactory, and those guards also began to have some discussions, they thought that the concept of explosives proposed by Li Gengyun could not succeed, or that this did not exist at all, and that with the combination of some sulfur and saltpeter, at most it could only form a ceremonial flower, and it was impossible to achieve the effect that a few explosives in Li Gengyun's mouth could raze the secret base to the ground. At this time, Li Gengyun himself even began to think that what he mentioned was a bit beyond reality, and with his current ability, he was not able to make explosives. But he thought about it, since Guo Feng also learned that there were fireworks that could blow up people's limbs, then explosives must exist, which was the reason for the proportion.

"Explosive No. 50 has been placed, and the oil rope has been connected! Please instruct! ”

"Ignition!"

Li Gengyun no longer gave the order directly, it was the head of the guard who gave the order. With an order, a soldier in charge of igniting the fire outside the pit ignited the oil rope on the bamboo pole, and then immediately ran away, hiding behind a boulder and waiting for the final result of explosive No. 50. If this explosive still fails to achieve the desired effect of Li Gengyun, then today's test will be a failure again. They're going to have to freeze here again for another afternoon.

"It must be done!"

Li Gengyun watched the flames on the oil rope gradually move towards the direction of the deep pit, and prayed secretly in his heart.

"Bang!"

"It worked!"

"It worked! Hahaha, Mr. Lee! It worked, explosive No. 50 succeeded! ”

With a loud bang, a strong dazzling light burst out from the deep pit, and the whole earth trembled, and at the same time, the stones that were shattered by the explosives flew out of the deep pit, and those stones even flew directly out of a hundred meters and fell in front of the boulder where Li Gengyun and the others were hiding.

"Whew! Finally it worked! ”

Li Gengyun saw that those guards cheered and cheered, and he also breathed a long sigh of relief, his original face was solemn, and he finally showed a relieved smile, it seems that his efforts have not been in vain!

"Mr. Li, the test of explosive No. 50 has been successful! This is the ratio of fifty explosives! The leader of the guards took the ratio of the fiftieth explosive and handed it to Li Gengyun, his face showed an excited smile, grinned and laughed, and said to Li Gengyun, "Mr. Li, with this thing, it will be so easy for brothers to kill the enemy on the battlefield in the future!" ”

"Uh-huh!"

Li Gengyun found that the ratio of No. 50 explosives was exactly the same as that of No. 39, and he immediately frowned, and there were some doubts in his heart.

"Why is Explosive No. 39 just an ordinary fireworks effect, while Explosive No. 50 has so much power? The ratio of the two is exactly the same, why is the gap so big! There must be something wrong with this! ”

Thinking of this, Li Gengyun handed back the No. 50 explosive ratio to the head of the guards, and then said to him: "Leave a few people to clean up the scene, and the rest will go back to the secret base with me!" ”

"Yes!"

The leader of the guards was also a little nervous when he saw Li Gengyun's face change, especially when he saw him frowning, could it be that the ratio of explosives was wrong? However, he didn't think much about it, so he arranged for two guards to stay here to clean up the scene, and the others escorted Li Gengyun to the secret base with him.

After returning to the secret base, Li Gengyun asked the four craftsmen who made explosives with a serious face: "Can you explain to me why the ratio of No. 39 explosives is the same as that of No. 50 explosives?" But the effects between them are very different! Who is the person in charge of the 50th explosive ratio?! ”

"Yes, it's me!"

At this time, the craftsman who first said that his ancestors were cursed and that many ancestors had been killed because of greed came out, and he looked at Li Gengyun with a worried expression. Seeing the serious expression on Li Gengyun's face, he was immediately shocked, and when he thought of the ratio of No. 50 explosive, he directly copied the ratio of No. 39 explosive in order to be lazy. When copying the ratio, he was also very apprehensive in his heart, the reason is that he didn't think that he would succeed, and it is normal to use red and white clay to make fireworks. The results of the experiment for two consecutive days were not satisfied, and he also lost confidence in the explosives they made, and he couldn't get five hundred taels of silver anyway, so he took advantage of the blacksmiths' inattention, and got some iron sand and iron filings from the side, which seemed to increase the amount of saltpeter and sulfur, but in fact, this time the amount of saltpeter and sulfur was only half of the original, and iron sand and iron filings accounted for half of this half.

"Mr. Li, please forgive your sins!"

Seeing the serious expression on Li Gengyun's face, the craftsman already knew in his heart that it was very likely that the other party had noticed the difference, and after mixing iron sand and iron filings, it was very likely that this explosive was a squib, and it didn't even go off.

"What's your name?!"

"The little one, the little one is called Wang Fujin, Mr. Li spares his life! The little ones don't dare anymore! The little lazy didn't compare saltpeter and sulfur twice, and picked up some iron sand and iron filings as fillers, which made the squib! Please forgive Mr. Lee! The little ones will never dare to do it again! ”

Wang Fujin hurriedly knelt on the ground and kept kowtowing to Li Gengyun to beg for mercy, and while kowtowing, he told how he was lazy and how he added iron sand and iron filings without others noticing.

"Someone!"

"Ahh Mr. Li spares his life! I am old and young, a family of five, all counting on me, Mr. Li, I am willing to join the army, join the army, go into battle to kill the enemy, and atone for my sins! I beg Mr. Li to spare his life! ”

As soon as Wang Fujin heard Li Gengyun calling someone, he was even more frightened, and he couldn't stop wailing in his mouth, and he bowed his head to Li Gengyun and shouted for mercy.

"Go and bring the reward and send it to the four master craftsmen! Wang Fujin! Well done you! Now I command you to write down the correct ratio of explosive No. 50, and I will reward you with another five hundred taels of silver alone! ”

"Huh?!"

Wang Fujin was still kowtowing and begging for mercy, but when he heard Li Gengyun say that he wanted to give them a reward, he was also stunned, and when he heard the latter sentence that Li Gengyun said, he was even more confused.

"Could it be that Explosive No. 50 succeeded?!"

"Succeeded?! Did it really work?! ”

"Well, it worked! Thank you very much! ”
