According to Wu Qin's idea, he had to take a false shot when he went out, so as not to be discovered by the city and notify Wu Xi, but Wu Zhongyuan did not adopt his suggestion, in the eyes of Wu Qin and others, he went out to hide, and in his opinion, he was going out on business, so there was no need to be sneaky.

shouted Dasha to come over, and took the old blind man and the second child to go on the road, at this time Wu Qin and his opinions conflicted again, he left Huang Mao'er behind, and continued to protect Wu Di, and Wu Qin was worried that they would not have a master accompanying them, and it would be difficult to ensure safety, so he had to let him take Huang Mao'er.

After a long stalemate, in the end he still brought Huang Mao'er, thinking about it carefully, it is indeed unlikely that Wu Xi will attack Wu Di, leaving Huang Mao'er is a serious waste of firepower.

Dasha lifted off and went west, Jiang Nan had gone to Gushan before, and he had to go over to pick her up.

With Huang Mao'er accompanying him, and there is a qi tonifying pill on his body, there is no need to bring a lynx dragon stick, he is really not good at using a stick, but after thinking about it, he still brought it, but he didn't take it himself, but made a crutch for the old blind man.

Jiang Nan's mother's health has not been very good, she is very filial, halfway back to Lianshan, the group rushed to Gushan when she just came back, Wu Zhongyuan did not delay from Gushan, picked her up and went directly to the north.

In Wu Zhongyuan's impression, he has stayed for a long time since modern times, in fact, he has not been away for long, there has been no major incident in the recent years, and it is not right to say that there is nothing wrong, Wu Yu did not lie that day, the bear clan's Da Yu was indeed attacked by a strange species some time ago, Wu Junyue did go to help, as for the battle situation, it is not very clear at present, I don't know what kind of alien is attacking Da Chu, Da Chu is the northernmost wall city of the bear clan, the transportation is inconvenient, and the news spreads relatively slowly.

According to everyone's previous plan, the next stop is the horse tribe in the northern Xinjiang, and this time they will go there.

On the way north, Wu Zhongyuan has been considering whether to go to Kunlun Mountain again, he has determined that the Yang Soul Stone does have a miraculous effect, and there is a black Yin Soul Stone on the lintel of the broken temple, which can protect the soul from injury, if you can get it, you will definitely be able to use it in the future.

After pondering for a long time, he finally dispelled this idea, the last time he passed, he also tried to exchange the soul stone with the red-haired little fox with the elixir, and the little fox also wanted to exchange, but was stopped by an invisible force, that invisible force not only prevented the little fox from taking off the soul stone, but also imprisoned the little fox in the broken temple, since the other party has taken precautions, it is even more difficult to think of the black soul stone.

The white Yang Soul Stone was still handed to Jiang Nan, but he handed it over, Jiang Nan dialed it back, although she didn't know the specific effect of this thing, but she knew that it did have a protective effect, Wu Wei only sent away his soul but failed to send away his body, this is the best proof.

Jiang Nan didn't answer, and Wu Zhongyuan handed it again. Jiang Nan pushed it back again, and Wu Zhongyuan delivered it again, and at the same time said with a straight face, "The legend is true, this thing does have the effect of protecting yourself, you can collect it properly." ”

When Wu Zhongyuan spoke, he secretly observed the expression of the second child with the corner of his eye, although the second child looked at them, there was no envy and covetous look on his face, which made him very satisfied, although the second child was cheap and poor, he was not greedy and had no ambition.

Wu Zhongyuan was casual and easy-going, rarely had a serious expression, and seeing his serious expression, Jiang Nan did not disobey him and reached out to take it.

Sending out the Soul Fixing Stone, Wu Zhongyuan turned his head to look at the old blind man, "Sir, do you know where there is a sacrificial furnace to heat up?"

"You want to build weapons?" the old blind man asked.

"Well," Wu Zhongyuan nodded, "I have never had a weapon to take advantage of, although I have dark iron, but it is difficult to melt and forge it,"

The old blind man closed his eyes and said nothing, not asking if he was recalling and thinking about what could raise the temperature of the hearth.

Seeing that the old blind man had not spoken, Wu Zhongyuan said again, "Do you know where there is a geothermal volcano, or where thunder often falls?"

The old blind man said, "I told you before that the Jiaoyi people who are located at the confluence of the river and the sea, in addition to making snakeskin dragon tendons, they also refine Jiao oil, which can be burned, and it is very hot, if you can get some, you must be able to use it to heat up the sacrificial furnace." As for geothermal volcanoes, there seem to be only two places, one is located near Tianchi in the northeast, and the other is located on an island in the southeast, but these two volcanoes only occasionally emit smoke, and most of the time they are fixed and silent, and they erupt very yearly. ”

Hearing the words of the old blind man, Wu Zhongyuan threw his eyes in admiration, the two places that the old blind man said should be the Wudalianchi area of Changbai Mountain and the Taiwan Island where the old Jiang Wei lived, in modern geography, these two places are indeed volcanic dense areas, and only these two areas have active volcanoes.

The old blind man said, "There is an island in the South China Sea, called Fire Island, which covers a vast area, and there are many rare birds and beasts on the island, and it is said that there is a valley there, called Thunder Valley, and in summer, there are thunderstorms almost every afternoon, but I have only heard of this matter, and I have not seen it with my own eyes." ”

"Sir erudite. Wu Zhongyuan Zhengse said, the fire island that the old blind man said should be the Hainan Island in the future, he doesn't know if there is a thunder valley in that place, but that place is indeed the place where lightning appears most frequently in China.

"Ashamed, ashamed. "The old blind man is humble, but he has a smile on his face, and there is no one who does not want to be recognized and appreciated by them, and the old blind man is no exception, and the most important thing is that the old blind man is not a very serious person.

"Sir, have you ever seen that oil burn?" Wu Zhongyuan asked again.

The old blind man didn't understand why Wu Zhongyuan asked this question, and turned his head in confusion.

Wu Zhongyuan felt that his expression was not very accurate, so he changed his question, "Flammable things have flames when they burn, and the color of the flames is different, and their degree of heat is also different, so what color is the oil when it burns?"

The old blind man understood, and replied, "Yiren has two skills of boiling salt with nitrate skin, which is used to make a living, and when boiling salt, Jiao oil will be added under the kettle, and the flames under the kettle are mostly red, and the fire will burn Jiao oil for lighting during celebrations, and the flame is blue." ”

Wu Zhongyuan nodded slowly, the red flame can reach a maximum of three thousand degrees, and the blue flame can reach a maximum of more than four thousand degrees, but this is only the temperature of the outer flame, and it cannot be regarded as the overall temperature.

Grease can indeed be used to raise the temperature, in ancient times, there were often people who could not practice the sword, the wife and children were thrown into the hearth, and then the flame swelled, refining into the legend of the sword, its essence is to use the grease to heat up, but it is not right to throw the wife and the child, and the effect of throwing a pig into it is actually the same.

However, 3,000 degrees and 4,000 degrees are not enough, 3,000 degrees is only a little higher than ordinary fireworks, and 4,000 degrees is not enough to reach the earth fire, that is, 5,000 degrees of volcanic magma.

"By the way," the old blind man suddenly remembered, "Yiren is buried in a cave, and there is an everlasting lamp in the cave where his ancestral tomb is located, and it emits purple light. ”

"Purple?" Wu Zhongyuan vaguely saw hope, people who practice qi will change with the improvement of aura cultivation, the color of aura will change, from low to high are red, blue, purple three colors nine, etc., people who know the spectrum know that the color of the flame is also like this, and the purple fire will only appear above seven thousand degrees.

"I was not blind then, but I saw purple. The old blind man said.

"Purple. Wu Zhongyuan rubbed his hands excitedly, the temperature of the thunder and lightning summoned by the wizard is not high, the temperature of the naturally formed thunder and lightning can reach about 8,000 degrees, and the purple fire is 7,000 degrees, which is not much lower than the heavenly fire and thunder, if you can get some of this grease back, there is no need to send Li Dashou to Hainan Island, the thunder and lightning are uncontrollable, and it is not accurate where to chop, but don't split the meteorite and kill Li Dashou.

"What do you want to do?" the old blind man asked with a smile, "That's the ancestral tomb of Yiren, do you want to extinguish the everlasting lamp of others?"

"Not really, I was just thinking that if I could, I might as well change some back. Wu Zhongyuan sneered.

The old blind man shook his head, "The grease used by the Yi people to worship their ancestors should be taken from some kind of rare dragon, which is very rare, and I am afraid that it will not be easily exchanged." ”

Seeing that Wu Zhongyuan's face was gloomy, the second child interjected from the side, "If you don't change, you will steal if you don't change." ”

Hearing the second child's words, Wu Zhongyuan frowned and looked at it.

Seeing Wu Zhongyuan frowning, the second child hurriedly said, "Big brother, you don't need to do this matter, I'll go." ”

Wu Zhongyuan couldn't help laughing, "Everyone knows that you are with me now, what is the difference between you stealing and stealing from me?

"We don't have to show our faces, we dig holes in the ground. The second laughed evilly.

"It's a bit lacking. Although the old blind man said this, his tone and expression showed that he did not object to the second child doing so.

Wu Zhongyuan smiled and said nothing, the lack of virtue is definitely a lack of virtue, but it is even more lacking in virtue to send Li Dashou to the island and risk being killed by lightning to build weapons.

Seeing that the three of them had reached a tacit understanding invisibly, Jiang Nan sighed helplessly, she was the second noble person of the Niu clan, bright and fair, and she was very repulsed by this kind of "chicken crowing dog thief" behavior from the bottom of her heart.

Wu Zhongyuan saw Jiang Nan sighing, but he only pretended not to see it, he can't be a man without a bottom line, but there is no need to demand himself according to the standards of a saint, who doesn't do something bad in this life, as long as it is not harmful to others and self-interest, there is no need to be angry. Taking a step back, even if he steals, he steals for the people of the world, but he is fighting for the survival of mankind, how can he do it without a weapon at hand. Taking a step back, any ever-bright lamp belongs to feudal superstition, and lighting a lamp for the dead with Jiao oil is a serious waste of strategic materials.

At the time of the shift, the group left Middle-earth and entered the northern border, where there was a clear dividing line, and the trees decreased significantly after entering the northern frontier.

The Vermilion Bird in the south and the White Tiger Wu Zhongyuan in the west have all been seen, and this time when they come to the north, they should go to see Xuanwu.

The area guarded by Xuanwu is located in the lower reaches of the Yinma River, which is a black water pool, which is not connected to the water of the Yinma River, but you can find the waterhole by following the Yinma River downstream.

However, their trip was to the Ma Clan, and there was a bit of a detour to see Xuanwu.

Just when Wu Zhongyuan was hesitating whether to go to the Horse Clan or see Xuanwu first, Jiang Nan suddenly raised his hand and pointed north, "Look." ”

Wu Zhongyuan raised his head when he heard the sound, and looked north along the direction of Jiang Nan, only to see a few black shadows in the northern sky, because the distance was still far away, he couldn't see it really, and it wasn't even a black shadow, just a few black spots.

Everyone was currently on the edge of the woods, and in order to ensure safety, Wu Zhongyuan instructed everyone to retreat into the woods.

A few black dots that appeared in the north moved very fast, and after a while, they were ten miles away, and at this time, Wu Zhongyuan finally saw clearly what was coming, it was a person, it was three people on horseback, and the leader was a tall woman wearing a dark purple cloak, riding a black horse with angry eyes, the black horse was strong, the dragon muscles were strong, and the clouds were born under his feet when he was running wildly. The two people in the back were wearing purple cloaks and riding two black horses, which were not ordinary things, but also cloud-stepping dragon horses.

These three Wu Zhongyuan all believe that they are all bear warriors, and the leader is Wu Junyue, the leader of the bear warriors, who has rushed to the aid of Da Yu not long ago, and may not have returned to the bear after expelling the invading enemy, but went north to the horse clan.

After the three dragon horses galloped south and disappeared, the second child looked at Wu Zhongyuan, "Big brother, should we still go to the horse clan?"

"the fart......"
