Dead end? Asked Allen.

"No," replied Galen at the front, "there is an iron gate blocking the road."

"Iron gate?" Alan was interested and strode forward.

The underground hole in front is much wider than before, about three meters high and two meters wide. Allen went to the front, and sure enough, he saw two dark iron doors blocking the way. The two iron doors fit closely with the underground hole without leaving a gap.

Alan came forward and touched the iron door. It felt cold and hard.

"Isn\'t it tungsten iron?" Allen sighed, touching the dark iron door. "It\'s too extravagant to use tungsten iron to forge iron doors?"

Ferrotungsten is one of the hardest steels found on the mainland. It is extremely hard and full of toughness. It is often used in the core of some advanced magic machines.

Allen said that casting iron doors with tungsten iron is a luxury because the price of a kilogram of tungsten iron in the market is as high as hundreds of gold coins! It doesn\'t seem expensive, but you have to consider the weight of these two doors.

These two doors weigh at least thousands of kilograms. If they are really tungsten iron, they are more than 100000 gold coins!

More than 100000 gold coins are enough to expand the scale of Huaxia collar several times, enough for Allen to summon several heroes, and even enough for Allen to open the second subsidiary element of the most Lord system!

But here, they are just two ordinary iron doors! Now Allen has an impulse to take down the two iron doors and take them back!

No wonder people say that the ruins of the dungeon are full of gold. They don\'t deceive me!

"Why is there an iron gate in here? Is it left by the former underground race?" Allen wondered.

"Of course, there are others who can leave an iron door here?" Lucius stroked his beard and looked at Alan like your boy\'s nonsense.

Allen scratched his head: "the iron door is not locked. See if you can open it."

Alan pushed the iron door hard and did not move.

"Galen, you come!" Ellen gave up. Lacs is a magician. Asso is agile. When it comes to power, Galen is the biggest here.

The power of demacia!

"I\'ll try."

Galen went to the door, put his hands on the iron door, bent his legs and pushed with all his strength.

"Ha!"

Galen almost used all his strength. Under Galen\'s push, the iron door made a few "creak" noises. Obviously, Galen did better than Allen, but he still couldn\'t open the two iron doors.

"Hoo..."

"No, I can\'t push at all," Galen breathed.

"Could it be locked from the other side," laches said. "The man who built this door may have lived at the other end of the cave. Because he didn\'t want to be disturbed, he built this iron door and locked it from the other side."

"That\'s a reasonable explanation," Allen said. "The iron door can\'t be opened. Why don\'t we think of something on the rocks of the cave wall."

"The frame of the iron gate is inlaid on the surrounding rocks. If we break these rocks, not the whole iron gate can be taken away!"

Alan became more and more excited and thought I was a real genius! Since there\'s nothing I can do with the iron gate, I\'ll do it on the rocks around me. It\'s called drawing money from the bottom of the barrel!

Lucius knocked on the surrounding rock wall with his hand: "it\'s steel rock. Are you sure you want to start on the rock?"

"How could it be steel rock!" Allen exclaimed. "Before, in the main cave, the rock wall was just a mixture of ordinary underground rock and soil!"

Alan said and touched the surrounding rock walls. After entering the sub hole, he really didn\'t observe the surrounding rock walls carefully.

As a result, the hard touch made him believe that the rock wall of this sub cave was really made of steel rock!

And it\'s a whole piece of steel rock!

"NIMA, we\'re out of luck!" Ellen couldn\'t help swearing.

Adamantite is of little value because it is too hard to process. Of course, the legendary strong may be able to, but which legendary strong will be bored to process stones?

But there is no denying that it is rare! If you choose a hole to escape, you can just pick the rock wall composed of steel rock. Isn\'t it bad luck?

"I think it\'s not your bad luck, but your good luck," Lucius said with a smile, stroking his beard. "Whether it\'s the rock wall of steel rock or the two tungsten iron gates, it indicates one thing, that is, behind these two gates, there are big secrets."

"If you can think of a way through these two doors, you may have unexpected gains."

"But how can we get through these two doors?" Alan frowned and thought hard.

"Why don\'t you help me?" Alan looked at Lucius pitifully.

From these days of contact, Allen has seen that Lucius is definitely a strong man. Although he doesn\'t know his specific level, he certainly won\'t be weak.

"Think of begging the old man?" Lucius smiled. "For the sake of your meticulous care for me and Belle along the way, I\'ll help you once."

"But for once, you\'ll have to rely on yourself."

"Thank you, old man!" said Alan happily.

Since Lucius promised to help, it proves that he is sure to do it!

Lucius walked slowly to the iron door, put his right hand on the right door, and suddenly threw out his strength.

"Boom!"

With a loud noise, the two doors opened, and the two doors hit the rock wall behind them.

Not only Alan, but also Yasuo, who had a cold expression all day, and Galen, who had a stiff face, were stunned.

Galen, the iron door that level 6 soldiers can\'t push, Lucius shook it open with one hand. How strong is he? Ten, eleven, even twelve?

While Alan was stunned, his eyes began to shine to Lucius. He must leave the old man in the territory! With him, unless the legendary strong attack, who dares to be presumptuous in China?

Several people walked through the iron door. Sure enough, they found a device similar to a door lock behind the iron door, but it had been broken by Lucius at this time.

"Master Lucius, do you think you can help me get these two doors down from the rock?" Alan walked up to Lucius and said pleasantly.

In Allen\'s eyes, these two gates are glittering gold coins. Of course, he doesn\'t want to give up.

Lucius gave him a white look: "want? Find a way by yourself."

Alan scratched his head and said if I had a way, would I ask you, old man!

"Old man, what level of martial arts are you, level 11 or level 12? You can\'t be a legendary strong man of level 13?" Alan asked curiously.

"Hum!" Lucius raised his head: "what legendary strong man, I\'m a god level strong man!"

Level 13 to 15 are legendary strong, and level 16 to 18 are God level!

The so-called God level, as the name suggests, is the level that God can achieve! It is said that the sun god and the goddess noe have only seventeen levels, and the only eighteen level existence among the gods is the destruction god kirius.

Alan\'s mouth is curled. He likes to boast at such an old age. God level? Why don\'t you just say you\'re God! Even the twelve heroes of ancient times, before entering the courtyard of God, their strength is said to be the legendary peak of level 15.

It is said that after the twelve heroes of ancient times entered the courtyard of God, although they awakened the sleeping destruction god kirius, several of them also obtained the inheritance of other gods and advanced to the God level, but there is no way to verify the authenticity of the legend.

"Since you can\'t take these two doors away, try to seal them temporarily so that the Giant Claw devil mouse behind won\'t catch up."

Alan looked at the two tungsten iron gates and said with great regret that they were 100000 gold coins!

Galen and asso close the two doors. Allen takes a table sized stone from the space ring and blocks it behind the door.

After blocking the stone, Allen clapped his hands and said with a smile, "with the strength and IQ of the giant clawed devil mouse, he should not break open these two iron doors."

Looking back, I found that everyone was staring at him with a strange look.

"What\'s the matter?" Alan asked strangely.

"Hee hee, Lord," said Lachs with a smile, "why did you put such a stone in the space ring?"

"Be prepared," Alan said with a smile. "You see, it\'s not necessary."

Several people continued to walk along the underground cave. After walking for some time, Allen wiped the sweat channel on his head: "do you think the temperature seems to be getting higher and higher?"

Galen, who was at the front, nodded: "the temperature is indeed rising."

Other people are not as hot and sweaty as Allen because of their high strength, but they all feel the rise of temperature.

After turning a 90 degree corner, Allen finally got out of the underground cave and entered a huge underground cave.

The solubility height is about twenty or thirty meters, the range is very large, the East and West are connected, and the edge can not be seen at a glance. There is an underground river in the cave. The temperature of the river is very high and it keeps steaming hot.

"The river here is so strange that it is hot."

Belle ran to the Bank of the underground river, stared at the river and said in surprise.

Allen knows that because the underground temperature is relatively high, sometimes this phenomenon is not surprising.

"Let\'s walk along the river. It\'s specially sealed with iron doors. Maybe there\'s something good," Allen said.

Several people went all the way along the river. After turning a few bends, the space suddenly widened.

However, they were slightly surprised by the scene in front of them.
