Except for Meng Zitao and Dajun, no one else could describe the shock in their hearts with words, and the whole person was stunned.

Yes, just like the scene that Meng Zitao encountered in the Shaokang Tomb, twenty or thirty meters in front of the cave exit, there is a flat land, and the flat land area is at least more than 5 square kilometers, which is much larger than the Shaokang Tomb.

The plains are densely populated with strange trees and shrubs, most of which are more than twenty meters tall, and some have even grown to the top of the cave.

In addition, the underground river flows from west to east, right through the plain, providing water for the plants here.

If there's sunshine, it's a paradise!

But it's another thing to have no light, and very few plants can survive in an environment without light, so how do these trees survive in front of you?

"Bang Bang!"

The sound of fried beans brought everyone back to their senses, and immediately after, everyone saw the sound of fire and explosions coming from hundreds of meters away, and it was mixed with the angry roar of wild beasts.

"What's going on over there?" Professor Qiu asked, a little nervously.

Meng Zitao looked at the place of the exchange of fire and said, "It is very likely that the people who are looking for the spirit guard are fighting each other. Armies, you watch out for them, and the others are familiar with their surroundings. ”

The army first took the security personnel down to guard, and until there was no security problem, they let Meng Zitao and them go down.

At this time, the two professors couldn't wait a little and began to study their respective areas of interest.

Professor Qiu ran to the tree, and immediately let out an exclamation from his mouth: "This seems to be a bitter oak!"

"How could a bitter tree grow in this place?"

Professor Qi didn't believe it, but on closer inspection, he found that it was indeed very similar to the bitter oak.

It is a deciduous tree with broad leaves and thorny edges, which grows in the south of the Yangtze River and north of Wuling, and is only found in the eastern part of Xishu and the northeastern part of Guizhou in the southwest. Found bitter oak here, and it was still in a lightless environment, it is no wonder that Professor Qi does not agree.

The trees that were suspected to be bitter trees had already borne fruit, and Professor Qiu asked someone to pick a few from a shorter tree.

The fruit that grows on the oak tree is quite similar to a hairy chestnut, and the hard-shelled fruit inside is the oak, the size of a thumb, also known as an acorn. It resembles a pocket waist drum, except that the top is pointed, like a bullet, and the bottom is like a drum surface, and it can make a beeping sound when struck with your fingertips. The shell is an uneven brown color, and when you shake it close to your ear, you can clearly hear the beating of the kernels inside.

Professor Qiu peeled off the skin of the fruit, and the fruit inside was the same as the common oak, and said excitedly: "At least eighty percent of the genes of the bitter oak!"

Professor Qiu looked at the forest in front of him and was very excited, these trees were priceless to him.

Meng Zitao took a quercille, peeled off the skin and the hard shell inside, revealing the flesh inside, the flesh is different from the common oak, it is translucent, and it smells like a fresh fragrance of rice, which feels very delicious.

In reality, the mountain people pick up the oak chestnut from the mountain and dry it, remove the hard shell, soak it in living water for a week, remove the single lemon in the astringent mouth, and then grind the pulp into a fine powder, filter out the coarse residue, and it becomes the oak powder, which can be eaten and used to make various foods.

The quercus in Meng Zitao's hand smelled as if it could be eaten raw, and if there were no toxic side effects, the people of the Exquisite Ancient Kingdom could use it to satisfy their hunger at that time, and the environmental disadvantages here could be reduced.

"Xiao Zhang, help me record the data!"

The unexpected discovery made Professor Qiu so enthusiastic that he didn't care about the gunshots coming from afar, and concentrated on his research.

Meng Zitao was actually very curious about the situation on the other side of the firefight, but he would not be stupid enough to deliberately go over and join in the fun, and take out the map he got before to check it.

Speaking of which, this map is really abstract enough, if he hadn't entered this place, Mencius Tao wouldn't have seen the similarities between the two.

In addition, I don't know what the points marked on the map mean to indicate that the place is in danger, or whether there are ruins or treasures.

Anyway, Meng Zitao must go to see these places, so as not to miss the treasure.

Just as Meng Zitao was studying the map, he suddenly heard an exclamation from Professor Qiu's side, he hurriedly looked back, only to see a tree in front of Professor Qiu, suddenly shaking, the leaves rustling, there was a sense of horror movie immediacy.

Meng Zitao walked over briskly and found that the trunk of the tree was dripping with a dark red liquid, as if it was bleeding!

"This ...... Could this tree be alive......" Professor Qiu was so frightened by the tree that he trembled a little when he spoke.

Meng Zitao asked, "Professor Qiu, what happened just now?"

Professor Qiu replied, "As you can see, I originally asked Xiao Zhang to take a sample, but I didn't expect that this tree looks like an animal, and it will bleed!

Meng Zitao shook his head: "I think this is right, generally speaking, plants are going to photosynthesize, and there are no such conditions in this cave, so in the long process of evolution, it came alive and became a special species integrating animals and plants." Because of this, it is able to survive underground without light. ”

Everyone felt that Mencius's explanation was very reasonable, but because of this, these trees were more attractive to Professor Qiu, and this forest was a priceless treasure in his eyes.

"Professor Qi, where have you been, how did you get like this?"

At this time, Meng Zitao noticed Professor Qi, who was belated, his body was not gray, and he looked as if he had dug up the soil somewhere.

Professor Qi replied, "I just found something, you come with me to take a look." ”

Meng Zitao led people to the place where Professor Qi said, which was a vacant land of 100 square meters, and this vacant land was left behind at a glance, and there were stone bricks on the ground.

In addition, in the center of the clearing, there are two stone statues, but the stone statues have been destroyed, one stone statue is intact and only one leg is left, and the other stone statue only has a third of its body left, and the upper part is damaged, so it is not clear what kind of stone statue it is.

In addition, in the middle of the stone statue, there is a pillar, the pillar has also been broken, Mencius Tao walked over, you can also see some ornaments carved on the pillar.

Professor Qi spoke: "Based on my years of research on the Exquisite Ancient Kingdom, these ornaments should be used on fire-related utensils, and just now I found some traces of burning in the wreckage on the ground, indicating that this pillar was likely to play a role in lighting at that time. ”

Meng Zitao agreed that people cannot live in a lightless environment all the time, and if this is a place where people in the ancient kingdom took refuge from disasters, then there will definitely be large lighting equipment, and if this is a fixed torch, it is considered a normal situation.

Professor Qi continued, "I suspect that there is probably more than one such place in the entire underground space. ”

Meng Zitao nodded: "Professor Qi, what's the use of finding these places?"

Professor Qi said: "This place seems to be just a place used by ordinary people, if the royal family also has such a venue, then it should not be far from us to find our target." ”

Meng Zitao was silent for a moment, then he took out the map and compared it: "Look at the shape here, is there any resemblance to the surroundings?"

"yes, it should be here!"

Professor Qi looked at the map and pointed to the side marked on the map very excitedly: "Let's go to this place to have a look, if it can be true, then it proves that the place marked on this map refers to the same lighting place as here." And this place is probably where the king lived at that time. ”

Meng Zitao also agreed with Professor Qi's opinion, and decided to go to the nearest place to verify first, and they returned to Professor Qiu's place.

Now that Professor Qiu is researching, he refuses to go there to verify anything, considering that this place is quite safe, Meng Zitao asked the army to stay here with security guards to protect Professor Qiu, and he plus Professor Qi and a total of four people went to the nearest point on the map.

After a short time, the gunfire gradually stopped, and the roar of the beasts could not be heard, and it was not known which side had won.

Considering that the side of the exchange of fire was relatively close to where the suspected king lived, there was a sense of urgency in everyone's hearts, and the speed sped up a lot.
