Chapter 684: The proud Xiao Quan

"However, even if it is black stone, I can still break it!"
"Look, the fire is slashing!" Ma Xuyun burst into a cry, the sword in his hand turned into an orange-red light, and then, a loud explosion sound came.
"Boom...!" There was a wave of sloshing in the underground water transportation channel, showing that Ma Xuyun's move was just powerful.
"Pun Pun Pun........." Numerous gravel dropped into the water, making a loud noise.
"Zi...!" The water in the underground water channel was poured on the fiery red wall, making a sound, then...
"Click...!" A few times, the hard black stone on the wall collapsed a large piece.
"Being mistakenly beaten by these people, the thermal expansion and contraction made them accelerate the speed of destroying the black gold stone wall, and the transportation was not bad!" Lin Ze on the ground smiled.
Originally, it took Lu Ming about half an hour to get through the stone wall built by the black gold stone. Now it seems that it can be opened up to about 10 minutes.
why? The reason is very simple, that is because of thermal expansion and contraction.
The use of the principle of thermal expansion and contraction to destroy stones is very common in ancient China.
When there was no explosives in ancient times, ores and stones were generally mined, and hard stones were destroyed during road construction. This method was used.
First, put a lot of firewood on the stone that needs to be mined or the stone that needs to be destroyed, and then ignite it to directly heat the stone and reden it. Then, pour a pot of cold water directly on the reddish stone.
"Zi..." With the sound of these sounds, you will magically find that this hard stone begins to crack.......
This method is most suitable for destroying stones, but if you want to mine stone, it is another way.
This method takes a longer time, and the principle is the expansion principle.
First drill a few holes in the stone with iron brazing. Then, nail a piece of wood that is about the size of the hole into the hole, and then continuously pour water on the wood.
After the wood is soaked in water, it will start to swell immediately, and then the stone will crack.......
"Haha..., it’s really God help me, with these waters, we can go out faster, hahaha..." I saw a lot of black gold in the water Under the rapid collapse, Lu Ming and Ma Xuyun laughed.
"Captain Ma, come on, we have to open the hole as soon as possible. The enemy may start to act now!" Happy to please, Lu Mingxin still understands clearly, so he urged Ma Xuyun to speed up.
"Okay, Commander Lu, I understand!" After that, Ma Xuyun carried the true energy of his body together, turned into a blaze of flames, and split towards the black gold stone wall in front of him.
At the same time, Lu Ming on one side also carried the true energy of the whole body, which also turned into a red flame, burning the black stone wall. When the time was right, he used the real gas to stir up a lot of water and wash the wall. Black stone burst naturally.
Some people may be wondering, why are the true energy of Ma Xuyun and Lu Ming both fire-like? Would such a coincidence be too coincident?
In fact, it's not just Lu Ming and Ma Xuyun's true qi that are fire attributes. In the Black Wind Bandit, no, in Wanlishahai, most of the true qi attributes of the warriors here are lost to fire.
The temperature inside the Wanlisha Sea is extremely high, and it is lost in the coldest winter. It has a temperature of 25-6 degrees. Normally, the temperature is around 37-8 degrees. When the temperature is high in summer, it is 60 degrees. not a problem.
This high temperature leads to the aura here, and the eight-level or higher are all auras with fire attributes, so most of the true qi of the martial arts practitioners here lose their fire attributes.
The warrior who changed to a water attribute is practicing here. Isn’t this just asking for bitter taste? !
Practicing the martial arts of water attributes in a place full of fire and spirit like Wanli Shahai. This martial artist is either a fool or his head was hit.
"Booming........!" A loud explosion sound came from the underground water channel, and many people on the ground heard these abnormal movements underground.
Soon, these abnormal movements were reported to Linze's main palace.
"Sir, there is a report below. There seems to be abnormal movements in the underground. A lot of people heard it and there was an explosion below. I went to see it in person and found that there was someone fighting under the ground." Tieying looked puzzled. Came to the main palace and said to Lin Ze.
"Oh, don't make a fuss. I've discovered the enemies in the underground long ago. Now there will be fighting below because I sent people to destroy these people, so that everyone should not make a fuss!" Lin Ze answered with a smile.
The situation below the ground is not understood by these people. If you want to understand such a complicated underground water transportation channel, the time required is constant. In addition, this time it is some powerful warriors who have infiltrated this time and let them deal with it. Lin Ze believes that Tie Ying and other people will definitely suffer huge casualties, and even Tie Ying, the masters that Lin Ze has fortunately cultivated, will also have big casualties. Therefore, this time, Lu Ming and others who eliminated the invasion, Lin Ze himself came .
"Admiral wise!" Tieying looked at Lin Ze with admiration. He didn't expect that Lin Ze had already made such preparations.
"Tieying, wait for you to take someone to the big water-pulling point on the left side of the east wall, and then bring me the ground mice back to me." Lin Ze ordered.
"Yes, lord!" Tieying went down quickly.
.................................................. ............
At this time, in the camp of the Black Wind Robber, Xiao Quan did not even look at Liu Yu and his party kneeling on the ground to blame. All his attention is now at the Dongcheng Gate.
"Now Lu Ming and they should have arrived at their destination, that is to say, there will be chaos in the Dongcheng Gate immediately, and I have to be prepared here first." Thinking of this, Xiao Quan said directly to his elder son Xiao Chengji : "Inherit, you go to the heavy cavalry to prepare for the attack now, waiting for my order!"
"Father, what do you mean..." Xiao Chengji was confused, he couldn't figure out why Xiao Quan asked him to go back to the cavalry force now.
This time the offensive has failed, even if it is to start the next attack, it will not let the heavy cavalry to attack.
Let the heavy cavalry attack a big city with a height of 40 to 50 meters. This is not an attack, but is giving away.
"Inheriting, Lu Ming has sneaked into the Black Sand City!" Speaking of which, Xiao Quan's face showed a proud look.
"Father, is this... is this true?" Xiao Chengji asked incredulously.
He had long discovered that Lu Ming and the guards were missing. At that time, he was wondering whether Lu Ming and these guards were sent by his father to do special tasks.
Unexpectedly, this is indeed the case. They were all sent by their father to sneak into the Black Sand City.
"Of course, you didn't find Lu Ming, and the guards around his father were gone. They were all sent to the father to sneak into the black sand city." Xiao Quan explained with a smile.
"Father, how did you let them enter Heisha City? Do you have any secret roads?" Xiao Chengji is worthy of Xiao Quan's eldest son and soon thought of the reason.
"It's a good guess, inherited. Father, I do have a secret road leading into Heisha City, hehe..." Speaking of which, Xiao Quan laughed proudly.
"Really!" Xiao Quan's affirmative answer relieved Xiao Chengji's nervous heart.
"Father, you have such undercover roads. Why didn't you say that we don't have to lose as many vanguard forces, and will you just pass through the underroad attacks soon?"
This is exactly what Xiao Chengji couldn't figure out. If there was a secret road, why did Xiao Quan let the vanguard army die? It is not good to send the army directly into the black sand city through the secret road?
"Alas, this secret road is not big and can only accommodate small troops." Xiao Quan explained, and at the same time, decided in his heart that after this time he recaptured the Black Sand City, he would directly dig a hidden passage~EbookFREE.me ~If something like this happens again in the future, you can enter the city through this underpass.
"Oh, that's what it is!" Xiao Chengji said suddenly.
"However, father, can you tell me where this secret passage is?" Xiao Chengji's face was curious.
Not only Xiao Chengji, but also other people, including Liu Yu kneeling on the ground to ask for sin, were full of curiosity.
"In fact, everyone has seen this secret road, but everyone will not associate it with it!" Xiao Quan replied with a smile, he was not prepared to keep the matter of the underground water channel secret.
He dispatched nearly 4,000 troops to sneak into the underground water transportation channel. This matter will be exposed sooner or later, so he now has no plans to conceal it, so as to increase the loyalty of the underground people to himself.
After all, Xiao Quan did not conceal such secret things as the underworld from his men, which shows that he really regarded his men as his own.
Who doesn’t want to work for someone who treats himself as his own? !
"Oh, we have actually seen it before." Xiao Chengji began to recall in his mind, looking for some special memories.
It's a pity that he found all the memories, but still couldn't find this'special' memory.
"Oh, stop thinking, you can't think of it." Xiao Quan said with a smile.
He didn't sell Guanzi anymore and said directly: "Heir, you forget those wells all over the city walls!"
Xiao Quan directly solved the puzzle.
"Water well?" Xiao Chengji frowned.
The next moment, he suddenly realized: "Father, is it..."
"Yeah, it's the underground water transportation channel." Xiao Quan replied affirmatively.
