The bonfire reflected the victors' cheeks, and everyone sang and danced to celebrate the victory. On the fire, there is roasted fresh meat and fragrant soup, and in the glass is old wine. People cheered, drank and indulged.

In the distance, Long Leiyan and Zhou Ruoxi, who met again, stood opposite each other. Both of them were silent, just staring at each other for a long time. From acquaintance to separation, all kinds of scenes are like movies, passing through the hearts of the two.

Suddenly, Long Lei Yan took a step forward and hugged Ruoxi tightly in his arms. Sometimes, an apology between lovers is purely superfluous, and a hug with a deep kiss is enough.

After a long time, Major General Long Da Ruoxi, who was about to lose his breath, let go. Ruoxi was already crying so much: "You, you know how to bully me!"

Long Lei Yan smiled innocently: "If I don't bully you, who will I bully?"

Zhou Ruoxi pinched Long Leiyan's nose and said, "There's no shortage of flowers and grass here, right?"

Long Leiyan's old face flushed, glanced at several beauties in the distance, and said embarrassedly: "Isn't this in the other world, I didn't expect to see you at the time, it's forgivable!"

Zhou Ruoxi snorted coldly and said, "You are wrong, this is not another world, this is the earth!"

Long Lei Yan was so shocked that he hurriedly said: "Impossible, this is absolutely impossible, where on earth is there such a big undeveloped land?"

Zhou Ruoxi said: "It's true above the surface, but what about under the surface?"

Long Leiyan hurriedly asked, "What do you mean?"

Zhou Ruoxi said: "You are still a high school student, let me ask you how many layers the earth's structure is in?"

Although he didn't finish high school, Long Leiyan still knew this bit of common sense, and said: "The earth's crust, mantle, and core are composed of three parts, and it is said that the earth's core is also divided into the outer core of the core. ”

Ruoxi said: "Yes, 100 points! But the answer is not comprehensive, there are still many huge gaps between the earth's crust and the mantle, and this is it!"

The preconceived idea that this is the otherworldly dragon Lei Yan really can't believe that he is inside the earth.

Seeing that he didn't believe it, Ruoxi took an instrument that looked like a laptop and said: "I didn't believe it at first, but you see, this is a multi-functional locator made by the tutor, we entered the Lawson Bridge at the beginning, in order to determine the orientation of the earth, recorded the earth's magnetic field fluctuation map, the magnetic field of each planet is different, to put it bluntly, it is equivalent to human fingerprints, you see the position displayed on the instrument now!"

Long Leiyan suddenly remembered Nole Verne's geocentric travelogue that he read in junior high school, which described a magical underground world, and he didn't think that he would be able to come to this world one day.

Zhou Ruoxi operated on the notebook and said: "What's even more surprising is that these people are not outsiders, they are also Chinese!"

Long Leiyan had been shocked by the series of news, and his big mouth couldn't close for a long time, thinking that the black-haired and yellow-skinned Huaxia people could be understood, but those blonde and blue-eyed people were also Huaxia people?

Ruoxi said: "They are the descendants of the Xia Dynasty who were defeated by Yin Shang, do you understand that?"

Long Leiyan suddenly realized that after the defeat of these Chinese ancestors, they hid in the underground world and developed another civilization, so it should be easier to return to the surface than to travel through time and space.

Ruoxi said: "The average thickness of the earth's crust is 17 kilometers, and if we rely on our current technology to manually dig tunnels, we will all die of old age and will not be able to go back." ”

Long Leiyan said: "Then look for the Lawson Bridge, we can just go back the same way, but I didn't find the Lawson Bridge where I first came." ”

Ruoxi said: "This is very easy to explain, the Lawson Bridge is a passage formed by the density and mass exceeding the bearing capacity of space, and its energy will be offset for various reasons!"

Saying that, Ruoxi pointed to the distance outside the city and continued: "Behind those dark creatures, there is a Lawson Bridge, which should be able for us to return to the surface, and the only difficulty now is how to clean up the dark creatures. ”

The big battle just now can be described as a complete victory, but what is cleaned up is only the dark creatures that are besieging the city, and there are countless dark creatures in the distance that are ready to move, and it is impossible to kill all of them without strong firepower, but now the most scarce thing is ammunition, Long Leiyan couldn't help frowning.

At this time, Wei'er suddenly appeared in her mind and said, "Didn't you find a lot of weapons in the tunnel?"

Long Leiyan said impatiently: "You stupid, it's on the surface, how can we get it? If you have the ability to move here, it's better to go home directly to save trouble!"

Wei'er glared and said: "You are stupid, since I mentioned these arms, naturally there is a way to get them, I have made a location in the tunnel, if the energy is sufficient, I can completely transmit those arms over!"

Long Leiyan was immediately overjoyed and said, "Then how good it is to get us back directly, why bother with all this effort?"

Vayl said, "Now I need to break up the subject matter into particles and reassemble them when I teleport items, do you want to try it?"

Long Leiyan was shocked into a cold sweat, is it still me who recombines his heart?

Weier said: "When I was fighting just now, I found a wave of energy, it should be a fragment of the crystal nearby, we can find it, all the problems are solved!"

At this moment, Long Leiyan had nothing to hide from Ruoxi, so he told Wei'er about her existence and suggestions.

Ruoxi found Wang Lie, the captain of the army, and the three of them sat together to discuss a plan.

There was nothing to say all night, and when the sun rose in the east, the three search teams composed of Long Leiyan, Po Jun, and the elite of the wolf clan set off, searched in the direction given by Wei'er, and agreed to return to the city wall no matter what happened after seven days. The hard work paid off, and three days later, Long Leiyan took Sha Hulu and Yelu Qian to finally discover the crystal.

On top of a mountain peak, this crystal was surrounded by a large group of dark creatures, Long Lei Yan estimated the balance of strength between the two sides, and felt that the three of them alone would definitely not be able to take it, and he should be able to return to the city wall and organize the whole team to come together.

By the time they returned to the walls of the fortress, the other two groups had already returned in vain. The meeting was held again to develop an action plan. This time, there was a target, and all the people cooperated with the action and slowly approached the peak.

At this time, countless elite troops turned into engineering soldiers, each with a shovel in hand, and dug three trenches around the hill, and the ditches were piled up with mountains of firewood, grass and oil. There was only one exit left in the trench, and the two sides were guarded by the broken army members with guns, and due to the difficult task, Long Leiyan concentrated all the ammunition that was left so far on them.

It took more than ten days to get ready.

One night, Long Lei Yan rode on the transformed little black black and roared at the sky: "The action begins!"
