Unexpectedly, Cheng Trend did not hesitate, immediately raised his right arm, pointed three fingers to the sky, recited the mantra, and said loudly with a fine mouth: "I, Cheng Chao, swear here, that I should strictly abide by what Xu Yi said, and never reveal it to others, if I violate this oath, I will be robbed by the thunder and die!

Xu Yi and Luo Ming were stunned, and Xu Yi was also forced to swear with the truth, but it was forced to do so, but Cheng Chao took the initiative to swear willingly!

After taking the oath, the essence in Cheng Chao's mouth turned into golden light and rushed to the sky, which means that the true word oath has been made. Cheng Cheng said: "Now you can tell the old man." ”

Xu Yi nodded and said, "Okay, since that's the case, I'll tell the old lady." The name of this thing is called explosives...... "It's rare that in Xu Yi's words this time, the seven CDs are true, so much so that Cheng Cheng has not been deceived.

Luo Ming was still a little puzzled at first, according to Xu Yi's urine nature, he was thankful that he could tell the truth three times, but he didn't expect that he would tell the truth this time. She didn't know that Xu Yi didn't even tell her the truth, and she couldn't blame Xu Yi, he just made up a lie and deceived Luo Ming that he had learned these explosives from a wandering poet, and didn't tell her that these were actually learned from the Internet.

At the same time, Xu Yi didn't bother to explain many scientific principles such as physics and chemistry contained in the explosives, so he casually made up an excuse to fool the past, based on the fact that only seventy percent of what he told Cheng Chao was true, which was consistent with the amount of information he told Luo Ming.

After listening, Cheng Chao said thoughtfully: "The golden spirit can refine all kinds of minerals from minerals, and I can't imagine that in the refined things, it can also create explosives with such great power. What is the amount of explosives used in the right person?"

Xu Yi said very dishonestly: "The amount used by Shicai is two catties of TNT explosives, and I worked hard for a while to make these." "It's still very convenient to calculate the catties of the other world, two catties is one kilogram of the earth, two catties is one kilogram, one kilogram of TNT explosives is equivalent to the charge of a 76 mm high-explosive bomb on the earth, this power is enough to turn a two-story building into rubble, the sand devil doesn't know how powerful, let a kilogram of TNT explosives explode close to the face, it is naturally the end of the separation of the body and the head!

Luo Ming's little face was a little unnatural, in fact, the two of them brought a total of six catties of explosives in the morning, and the four catties of explosives were thrown into the sea by Xu Yi to blow up the enchantment.

Cheng Chao slapped his thigh and said: "It's so powerful, with this explosive, even if you are not an ordinary person of the spirit, you can use this thing to kill a strong sand demon, this is where I call hope!"

Xu Yi asked tentatively: "But my husband and wife have discussed it privately, although this thing is very powerful, but after it appears, it will threaten the status of the spirit, but I am afraid that all the spirits will oppose it." ”

Cheng Chao laughed and said: "It would be biased to think like this, after the appearance of this explosive, how can it threaten the status of the spirit? You must know that the spiritual power spell of the spirit can do many things that ordinary people can't do, just like your golden spell can extract explosives from minerals, can ordinary people do it? What's more, ordinary people can use this explosive, but the spirit person can't use it? If an ordinary person and a spirit person use explosives to fight at the same time, I think the spirit person has a better chance of winning!"

Xu Yi and Luo Ming glanced at each other, and there was a sense of sudden enlightenment, as Cheng Chao said, the appearance of explosives does not threaten the status of the spirit, the two can coexist, and no one stipulates that the spirit cannot use explosives. On the contrary, if an ordinary person fights with a spirit, both sides use explosives, and a spirit like Luo Ming still has a spell defense, and an ordinary person has nothing, the natural balance of victory and defeat will be more inclined to the spirit.

On the contrary, if two spirits fight to the death, and one uses explosives, it will take a great advantage, and it will help improve the combat effectiveness of the spirits.

Xu Yi nodded heavily and said: "The old lady can see it thoroughly, in the future, my husband and wife will open an explosives shop to sell explosives, and it will definitely be a prosperous business and a wide range of financial resources." ”

Cheng Chao and Luo Ming both had a black line, Luo Ming pinched Xu Yi again, and said angrily: "Can you be serious, the old lady is talking to us about the future and destiny of the human race!"

Xu Yi bared his teeth, rubbed his arm and said, "I know, let's open a shop and sell explosives to our Terran spirits, it's okay." ”

Cheng Xun said with a smile: "Village Chief Xu can invent this thing, it is indeed a great merit for the human race, and it is also appropriate to get some benefits." After a pause, he said: "However, this matter should still have the support of the nine major clans of Donghai County before it can be done." How many explosives can you make a month? If it takes two pounds of explosives to kill a Sand Devil, how many years will it take you to build the amount of explosives needed to sustain a battle?"

Xu Yi was a little speechless, he just wanted to use explosives to save his life at first, but he didn't expect Cheng Chao's pattern vision to be broader, what he thought of was how to use explosives to lead the human race to counterattack the Sand Demon Clan! Xu Yi's spiritual power alone is limited, and the pit father's spiritual speech technique can only recover his spiritual power once a day, even if he doesn't rest every day for a month and steps up to make explosives, he can't make many catties of explosives in a month.

The amount of explosives made by one person is okay to provide for people to kill people and use them for home travel, but it is far from enough to supply a war. Unless all the spirits in Tokai County, plus ordinary laborers, set up an arsenal and produce explosives in large quantities, it may be possible to supply enough for the war within a year.

And now the civilization of the human race in Donghai County is still basically in the agricultural stage, there is no shadow of industrialization at all, the area is small, the population development is limited, and more can only rely on the spiritual power spells of the spirit.

Xu Yi frowned and said, "What the old lady means is that this matter can only rely on the power of the big clan to mobilize all the golden spirits in Donghai County to make explosives in large quantities, so that the effect of explosives on the human race can be maximized?"

Cheng Trend nodded and said, "If this explosive wasn't used like this, I can't think of any greater effect on it." If it can only provide some help for sporadic battles, then it is better not to use it, otherwise the Sand Demon Clan will definitely be on guard when they know that our Terran has such a powerful thing, and it will not have the effect of a surprise attack. ”

Xu Yi nodded, it seems that although this old lady has been in hiding from the world for many years, in fact, he has not forgotten for a moment how to lead the human race to fight back, his vision and ambition are greater, he wants to make a large number of explosives, and launch a surprise attack on the sand demon clan, so that the power of explosives can be brought into greater play.

"Then what are you going to do?" Luo Ming interjected and asked, she also understood what Cheng Chao meant.

Cheng Chao's cloudy eyes were shining, and he said loudly: "The old man plans to return to Donghai City, return to the Cheng clan, introduce you to the county guard, and then persuade the Li clan and other big clans that at the time of this expedition, we will send more soldiers and horses out to launch a surprise attack on the Sand Devils, instead of sending an expedition of only one or two hundred people out to send them to death as before!"

Xu Yi was immediately interested when he heard this, thinking that this time he received the order for an expedition, even if there was explosives, it would be a matter of nine deaths and a lifetime, if he could really tell Cheng Chao that he would send more Terran troops to go on an expedition together, if there were many people, the chances of himself and Luo Ming surviving would be greater.

Xu Yi's eyes lit up and turned around a few times, and he immediately said: "Exactly, we can no longer be like the gourd baby and grandpa, go to the death in batches, if we want to do it, we can do it, so that the Sand Demon Clan knows how powerful our human race is! Daughter-in-law, how about it? How about doing what the old lady said?"

Luo Ming knew that he was talking nonsense again, what kind of gourd baby saved his grandfather, but sending him to death in batches is to the point, Luo Ming's expedition is to find his father's whereabouts, if he can survive, it is naturally the best, and if this expedition can be accompanied by an army, the probability will naturally be greater.

At that moment, Luo Ming also nodded and said, "I listen to you." ”

Xu Yi was a little angry, when did this little girl hear about herself in private?

Cheng Chao stroked his palms and smiled: "Good, good, good, if a virtuous couple dedicates this thing, there will be hope for our human race to reverse the decline and decline!" It can be seen that the old man is sincerely laughing from the heart, and it is really good to regain confidence and hope.

"Taigong, there are a few things you haven't explained, what happened to that Sand Demon Neidan just now, and why can't we see your spiritual power with Spiritual Meditation?" Luo Ming then asked.

Cheng Chao was in a good mood, and the whole person suddenly brightened, and said with a smile: "You kid is a blessing in disguise." According to the records handed down, after the spiritual people in our world plant the spiritual root, they will produce spiritual power inner pills in their bodies, and if they kill spirits of different races, they can absorb the spiritual power contained in their spiritual power inner pills. Just in time, he got the inner pill of the sand demon man, and used alchemy to refine the inner pill, and the spiritual power of the sand demon was absorbed by him. ”

Xu Yi was overjoyed and said, "Then now I am a Xuanling-level spirit?"

Cheng Trend nodded and said: "Count your kid's life big, it just so happened that the old man was present and saved your life, otherwise if you forcibly refine like this, the abundant spiritual power will definitely burst your body!"

Xu Yi laughed and said, "My luck is really good. Then he said happily: "Then in the future, if we kill the sand demon man, we will be able to dig up his inner pill to absorb spiritual power and improve his cultivation." ”

Cheng Cheng said: "That's right, but refining the Inner Dan and absorbing the spiritual power can't be like you, you have to go step by step and refine it slowly, I have a basic spell here, called the Spirit Absorbing Technique, which is used to absorb the spiritual power of the Inner Dan." It's just that in the past few hundred years, there has been no foreign inner pill for the spirit absorption technique to play a role, so that this basic spell has been lost, that is, my Cheng family has retained this spell, and it just so happens that I will too. ”

Xu Yi touched his chin and said, "Why do you have to be a foreign clan's Inner Dan?" "After the human race spirit dies of old age, aren't those Inner Dan wasted? Xu Yi is fighting this crooked idea.

Cheng Chao shook his head and said: "Spiritual power spells are a gift from God, spiritual power has the power of compassion, if the inner Dan between the same clan absorbs each other, I am afraid that there will be a tragedy of cannibalism among the same clan, which is contrary to the original intention of God to give spiritual power. ”

Xu Yi nodded, and Luo Ming asked again, "Then why can't you see your spiritual power?"
