Early the next morning, Yang Ling'er knocked on Zhang Yang's door.

In fact, Zhang Yang had already woken up, and he didn't even need to sleep, as long as he sat down and rested, it was equivalent to an ordinary person sleeping for eight hours.

But he still maintained his usual style and worked and rested on time. When he heard the knock on the door, he knew that it was Yang Ling'er, so he said, "There is no latch, come in." ”

Before Yang Ling'er could ask anything, Zhang Yang said: "Ling'er, I thought about it last night, I always felt that we hadn't searched for the place we went to yesterday, and we must have missed something, so I plan to go today." Are you tired?"

He doesn't ask you if you're going, but if you're tired. This is his carefulness, and it also fully reflects his love for Yang Ling'er.

"I'm not tired, I'm still going. Yang Ling'er knows Zhang Yang's thoughts, although she is a girl, but she is the runner-up in the long-distance running in the school, and her physical fitness is much stronger than that of ordinary girls.

Zhang Yang smiled, touched her hair, and said, "Let's go, go downstairs and leave after breakfast." ”

Yang Ling'er said "um" and obediently followed downstairs.

Half an hour later, they reappeared on the road to the back mountain. This time, Zhang Yang brought the recovered light wave dagger.

Entering Hole D, Yang Linger found that the small hole that had been blasted had disappeared, and she couldn't help but scream.

Zhang Yang smiled and reassured: "It's okay, it's just that someone is making trouble." ”

But I snorted in my heart, what kind of thing, dare to play such a trick, see how I clean you up!

He continued, "Ling'er, you know my lightwave dagger, today we're going to test its true power. ”

It is said that this is the first and only one since the establishment of the academy that you have been affirmed by these bigwigs. ”

"It's just my luck that the other students didn't think of digging out ideas in this area and took the lead. ”

Zhang Yang is very modest, this is also what he said in his heart, he doesn't think that he can surpass anyone, it's just that he can do it, he has to think a little more and put more effort into it, so that he will not fall behind.

Yang Ling'er smiled, tall but not arrogant, this is the Zhang Yang she fancies.

"Your work is said to be able to split a stone easily, which is remarkable, it's the equivalent of a small nuclear weapon that you carry around." ”

When it comes to the efficacy of the light wave dagger, Zhang Yang is not modest, but realistic, he said that it can emit a strong shock wave within ten meters, which can kill any fierce animal and penetrate any obstacles.

This surprised Yang Ling'er a lot.

Although they are classmates and lovers, but in the College of Science and Technology, there is an unwritten rule that you cannot spy on the creativity of other students, and the senior management of the college only said this at the conference, the purpose of which is to encourage students to innovate independently and not to be affected by the works of other students, but they did not expect that it has become an unwritten agreement between students and students, which is unexpected by the senior management of the college.

However, because Zhang Yang's works are relatively special, on the one hand, they have been affirmed by the college bosses and attracted the attention of the whole school, and at the same time, she is close to Zhang Yang, so she keeps the light wave dagger firmly in mind.

I believe that if I changed to any other student, I would have forgotten it a long time ago, because there is a science and technology college of Nuo University, and different new works emerge every day, and several propaganda columns and college science and technology newspapers of the college are updated every Monday, and everyone is attracted by the latest news, which is like other ordinary universities, such as a certain student wrote a very good composition, which was a sensation after being announced, and then forgot it early, who will remember who and who's what works before.

"It can penetrate any obstacle within ten meters, that is, as long as you wave the light wave dagger towards the stone wall, the stone wall within ten meters will become a stone ballast, and if you do it again, it will be twenty meters......"

Yang Ling'er didn't dare to continue, oh my God, this is more bullish than any **, and it doesn't waste any resources.

Thinking of this, she immediately reacted and said, "Zhang Yang, start digging the mountain!"

Zhang Yang couldn't help laughing, although Yang Ling'er was joking, she was not wrong, the rhythm of the light wave dagger was really "the rhythm of digging mountains".

"Howler. Zhang Yang responded, after speaking, raised the light wave dagger, and slashed towards the stone wall in a shape, only to hear a loud rumbling sound, only to see the stone ballast flying, and in a moment, an oval, about ten meters deep cave appeared in front of him.

He then entered the cavern, and continued to make shapes and strokes, a dozen times in succession, and a dim light shot in at the same time as the last stone barrier was cut.

Since the ballast cannot be transported outside the excavated cave, the entire cave can only be entered and exited by one person.

Zhang Yang walked in front, and Yang Ling'er followed closely, and after a while, they found that in the cave they entered, there was a passage that could not see the edge. What made Zhang Yang feel strange was that the stone walls around this cave were also the Night Pearl Rough Stone, and he said that when did the Night Pearl Rough Stone start to be so worthless.

Yang Ling'er's eyes widened, and she touched the cold stone wall of her tentacles in disbelief, and asked vigorously: "Zhang Yang, Zhang Yang, is this true? This is the original stone of the Night Pearl!"

At the same time, she secretly thought that on the day she and Zhang Yang got married, the new house would not be lit, so it would be replaced by a night pearl, which is how romantic and extravagant it is!

Looking at Yang Ling'er, who was almost out of shape, Zhang Yang understood her mood very well at this time, this was not an ordinary shock. Who made the Night Pearl a rare thing, if it was replaced with any ordinary jade, it would not be so shocking, at most it would be a few words of amazement.

After a good time, she also recovered from the shock, and all the way over, the stone walls she saw were all the rough stones of the Night Pearl, and she seemed numb.

But what made them strange was that the "monster" they saw on the video didn't even have a shadow along the way. Zhang Yang thought, it must be in the wrong direction, the 001 reconnaissance plane was discovered from the periphery of the mountain through perspective, and the two of them walked out from the inside of the mountain. But anyway, the monster is in this hole.

So he whispered a few words to Yang Ling'er. Yang Ling'er nodded and said she knew.

Walking like this, although they didn't look at the time, it was estimated that it was about half an hour, and they found that there was no road ahead. Yang Ling'er was a little disappointed at this time, she said that this was just a rough stone cave in the Night Pearl, and those monsters were not here.

Zhang Yang smiled: "Haven't you heard the story of the tunnel war?" "Of course I've heard of it, I've read a few novels, but it's wonderful! Why, this is related to the tunnel war?"

Yang Ling'er obviously didn't react to what Zhang Yang meant when he said the tunnel war, and he meant something.

"Is that really all there is?" Zhang Yang had a teasing expression.

"What a look on your face. Yang Ling'er picked up her small fist and waved it at Zhang Yangyang. In fact, she still didn't understand what Zhang Yang meant by tunnel warfare.

Zhang Yang laughed, he liked to see Yang Ling'er in a frame like she was going to fight with him.

Then he explained: "What I mean by that is that there is a hole in a hole here. ”

"Where is the cave in the cave?" Now she finally understood the meaning of the tunnel war that Zhang Yang was referring to.

But she didn't dwell on this topic, and her interest immediately shifted to "where is the hole in the hole".

"Let's look for it. Zhang Yang said seriously, "Ling'er, let's look for it separately, you go to the left, as long as it doesn't seem very reasonable, notify me." ”

In fact, the reason why he thought of the cave within the cave was, of course, not related to the story of the tunnel war, but the experience of the last mass grave underground.

"Well!good!" Yang Ling'er replied very simply, and looked carefully at the stone wall on the left, she was afraid that her eyes would be bad, as long as the stone wall with a little bit of characteristics, she would reach out and touch it, and then feel it silently.

Just as she was seriously searching, Zhang Yang's shout was heard, "Ling'er, come here, come here." He ran in three steps and two steps. He asked, "Did you find the entrance?"

Zhang Yang nodded, pointed to a stone wall that was obviously much dimmer than the surrounding area and said: "Ling'er, look, although this stone wall is also the same as the others, there is no trace to prove that this is the entrance, but have you noticed that the brightness of the Night Pearl Rough Stone in this oval range is obviously much dimmer than the brightness of the stone walls in all locations here." So, there is only one reason why it is so much darker, and that is that this is a secret door. Zhang Yang explained.

"Your observation and analytical skills are comparable to those of a certain detective. Yang Ling'er praised it sincerely, and carefully looked at the stone wall within the scope of this oval, and nodded affirmatively, "It's here, but how can we open this secret door?" She raised her head and stared at Zhang Yang with big eyes, she believed that Zhang Yang could give her a satisfactory answer.

"I'll look for it. Zhang Yang said, stretched out his hand on the stone wall within the scope of this oval, patted rhythmically, and secretly used his internal strength.

Sure enough, I only heard a click, and I saw a slight tremor in the stone wall within the oval range, and slowly, along the range of the oval, the stone wall began to sink inside, and after a while, an oval-shaped complete hole was exposed in front of the two of them.

"Let's go in. Zhang Yang said, reached out and took Yang Ling'er's hand, and walked into the hole where the secret door was completely opened. "Zhang Yang, look, there's a stone painting here!" Yang Ling'er pointed to a stone face on a stone wall in front of her and said to Zhang Yang.

Looking up, Zhang Yang was stunned for a long time, this painting is too familiar to him, the style and layout of the whole picture are the same style as what I saw in the underground of the mass grave before, but the characters inside have changed, sitting on the chair is the fourth regent who originally knelt at the back, and kneeling below him are ten faces. In the cave under the mass grave before, he had carefully looked at the appearance of each portrait, and he never doubted his memory.

"How can this be the portrait of the fourth regent?" Zhang Yang was a little confused, because whether it was Little Gray Ash or Big Bear, in their descriptions, there was only one king in the distant world, but it was definitely not the fourth regent, even if the old king abdicated, he should be succeeded by his eldest son Truss, because Truss himself was already the supreme ruler.

This made Zhang Yang suddenly remember what Little Gray Ash said: Later, for some reason, people from the distant world couldn't reach here, and they could still be contacted through the mirror at first, but then they couldn't be contacted at all.

Is there anything that can't happen?
