The steam train rumbled away from the northwest and re-headed for the Central Plains from the mountains.

Da Fu was concerned in the car: "Young marshal, you can rest for a while, you didn't have a good rest when you camped temporarily yesterday, and this Daxing Northwest is really not in a hurry at this time." ”

Ren Xiaosu shook his head and said, "I'm not sleepy yet, so you go to sleep first, and you wake up in six hours to take over from me." ”

"Okay, then young marshal, you are tired and tell me," Da Flicker is indeed sleepy, from the time they went to the Central Plains to turn people up to the northwest, both of them have not had a good rest for more than 20 hours, although they are both transcendents and have more energy, but the age of Da Flicker is old after all.

Ren Xiaosu was actually a little sleepy, but he couldn't wait to see what the third weapon in his palace was!

When Da Yu entered the carriage to sleep, Ren Xiaosu immediately said to the palace in his mind: "There are now fifteen thousand thank you coins, and the conditions for unlocking the third weapon have been met, right?"

"Yes, do you want to spend 10,000 Thank You Coins to unlock?" asked the palace in a voice.

"Unlock!"

Ren Xiaosu waited silently, but this time the weapon unlocking was nowhere to be seen.

Inside the palace like a circular library bookshelf, a delicate little lattice lit up, but the inside was empty.

He was a little puzzled: "Where's the thing?"

The palace did not answer him.

Suddenly, the palace began to shake, and Ren Xiaosu felt something in his heart and stretched out his right hand flatly, and a hot but not hurtful energy was gathering in his hand.

Above the canopy above the steam train, a huge whirlpool began to condense.

The steam train is moving at high speed, so the huge whirlpool overhead is also moving rapidly with the steam train.

Fortunately, this is a wilderness of five people, otherwise someone would definitely be frightened by this vision of heaven and earth.

In the gray whirlpool, a purple eye suddenly appeared.

Ren Xiaosu looked at his outstretched right hand in a daze, and the big flicker in the next carriage was also alarmed, and hurriedly pushed open the door and ran to the front of the car: "Young marshal, I think something is wrong, young marshal! An eye appeared on the top of his head, did I leak too much heavenly secrets, and God came to collect me?"

"Leaking the heavenly machine?" Ren Xiaosu complained with a smile: "What kind of heavenly opportunity have you leaked, it is clear that you are deceiving people a lot!"

However, at this moment, the huge energy in Ren Xiaosu's hand suddenly began to condense, and it actually produced a black stone.

The black stone was only the size of a fist, and it was a little warm to hold in his hand, but the most strange thing was that the whirlpool above the sky had begun to fade away, and the purple eyes on the whirlpool appeared on this black stone.

Ren Xiaosu asked in confusion in his mind, "What is this?!"

But the palace replied, "I have no right to tell me." ”

At this time, he looked around Ren Xiaosu in surprise for a long time, and finally his eyes fell on Ren Xiaosu's hand: "Young marshal, the vision in the sky just now is related to you?"

Ren Xiaosu didn't hide it, so he nodded, he didn't say the origin of the black stone, and he didn't ask more.

Ren Xiaosu looked at the palace silently, this time, the palace did not prompt the unlocking progress of the next weapon, that is to say, this is the last weapon that the palace can give him!

Then the question is, I am about to earn tens of thousands of thank you coins, what can these thank you coins do except exchange for burst poker and plant seeds?

But I saw that the vending machine in the palace actually had a new commodity grid lit up at this time, and there were small gray-white stones inside, each stone was exactly the same shape, and there were also eye-shaped lines on it.

Product name: Skilled stone.

Ren Xiaosu was stunned for a long time, what is this, what kind of nerves did the palace suddenly have, and he cleaned up something that he couldn't understand.

It's just that he doesn't know why, he suddenly feels that this skillful stone that can be sold, and the third weapon in his hand may become very important.

Since he owned the palace, although the palace does not look serious, he has not done anything superfluous!

Ren Xiaosu exchanged a thank you coin for a skilled stone, this thing was very soft in his hand like a lime block, and he crushed the skilled stone with a little force in his hand, but the problem was that there was still no reaction after crushing.

The palace suddenly spoke in his mind: "There is no corresponding ability to increase proficiency, and proficiency stones are invalid." ”

Ren Xiaosu muttered in his heart: "What the hell is this, don't you have so many extraordinary abilities, why don't you have the corresponding ability, then what are you doing with this skilled stone?!"

Palace: "No permission to inform. ”

However, at this moment, Da Yu suddenly said on the side: "Young marshal, the black stone in your hand, I look a little familiar." ”

Ren Xiaosu was stunned for a moment and looked at the big flicker: "Do you recognize?"

"I'm not sure," Da Fool whispered, "You also know that our 178 Fortress has fought with the enemy outside the northwest, and although all the battles have ended in our victory, the 178 Fortress has also paid an extremely heavy price. The last time I fought was 17 years ago, when I was only a company commander, and by the time I had the enemy repulsed, I had only 20% of my comrades left in a company. This eye sign is a bit similar to what I saw at the time. ”

"You mean, this kind of thing appeared in that war?" Ren Xiaosu wondered.

"Yes, when we cleaned up the battlefield later, we saw a few broken pieces, and they were put together in the shape of this eye," Da Yu recalled: "It's just that those stones look tattered, and they are not as delicate as those in your hand, and the eye lines are also very blurry." At that time, the commander also ordered us to look for it, but we only found the broken one, and we didn't see a whole piece, so I don't know what it does. ”

"Are they all shattered," Ren Xiaosu muttered in a low voice, "What exactly is the enemy outside the northwest, and why are they here?"

"The enemies outside the northwest are also human beings, but they are a little different from our race," said Da Yu, "It is said that at the beginning of the catastrophe, that is, about two hundred years ago, they began to come to our territory to plunder the population, and a large number of compatriots were robbed by them to places outside the northwest, and it is estimated that the number may be hundreds of thousands, or even millions. The 178 fortresses were also built specifically for them. At that time, our human civilization in the Central Plains had not yet been revived, and they seemed to have a mysterious inheritance before the catastrophe, so the martyrs were extremely difficult to face them, and there were many casualties. ”

Ren Xiaosu pondered, millions of people were looted in the early days of the catastrophe? At that time, the number of people in the entire Barrier Alliance was probably only a few million, not as many as tens of millions now.
