Just as the two of them were observing the battlefield that was about to break out outside the forest, the little ape-man behind them suddenly let out a cheerful cry and ran towards the group of ape-men.

Not far away, on the imminent battlefield, both sides turned their eyes to this side.

Two humans wearing Type 12 armed police special operations training uniforms had no choice but to stand up, they hid in a glowing plant, and the camouflage color on their bodies did not match the world, because none of the plants here were green, which made them look somewhat weird here. This is one of the reasons why they managed to get here, and the other beasts did not attack. Just as we see the stinging red poisonous frogs, colorful caterpillars, and brightly colored poisonous snakes, the body color that contrasts with the environment can play a role in deterring and warning the enemy, and the 12-type armed police special operations training uniform with green as the main color has unexpectedly become the warning color in the eyes of those underground creatures.

As for why the plants here are not green, under normal circumstances, the photosynthesis of plants is divided into light reaction and dark reaction, light reaction is the process of photolysis of water, production of oxygen, and conversion of light energy into chemical energy, and dark reaction is a series of enzymatic reactions. In this space, which was gradually closed to no sunlight, plants evolved into their current form over the years, absorbing nutrients from their roots, replacing the main light reaction in photosynthesis with dark reactions, and entering the fiber ducts of microorganisms, nitrogen-fixing bacteria, and prokaryotes (cyanobacteria) that can carry out oxygen-producing photosynthesis into leaf veins, and generating high-energy electrons through cooperation with these bacteria, thereby converting light energy into electricity. The electrons are then transferred through the movement between the electron transport chains in the thylakoid membrane in the plant, and the H+ protons are used to establish an electrochemical proton gradient for the synthesis of ATP to produce oxygen, re-completing the unique energy conversion process in this specific environment. Because the light reaction has lost its original important role, the chlorophyll in the plant body is becoming less and less, and carotene, lutein and other thylakoid pigments have replaced the position of chlorophyll, and it has become the unique plant color in the underground world.

Well, this little ape-man was the fuse of this war, and now those apes have found the granddaughter who suspected this kidnapping, so they left here under the leadership of the wise old ape-man, and the battle ended early because of Zhao Xinghua's unexpected appearance. But in the underworld, there will soon be an existential national war on the horizon, which is another reason why the two sides do not want to break out in a full-scale conflict in advance.

Zhao Xinghua and Xie Yunhao were not treated as VIPs, their fancy clothes did not match the cultural aesthetics in this closed space, and the communication between the two sides was not very smooth.

In modern Xiaoxiang Province, the Chinese dialects include Hunan dialect, Southwest Mandarin, Gan dialect, Hakka, in addition, there are Hunan native dialects and Waxiang dialects.

Xie Yunhao is a native of Xiangtan City, Xiaoxiang Province, and speaks the local Hunan language of Tanzhou, which is the most representative dialect in Xiaoxiang Province, mainly distributed in Tanzhou, Xiangtan, Zhuzhou and other central regions of Xiaoxiang.

In ancient times, Xiaoxiang was mainly inhabited by the "Sanmiao" tribe. Later, the Sanmiao tribe grew up in the area and established the Chu State regime, which was historically called "Jingman". The ancestors of the Chu State are said to be the Zhurong tribe of the Central Plains, surnamed Mi. "Historical Records of the Chu Family" said: "The ancestor of Chu came from Emperor Gaoyang. However, the state of Chu has always been despised by the northern regime, and the state of Chu has also publicly declared: "I am a barbarian, and I do not speak to China." Therefore, Chu language, as an early Hunan language, is different from Central Plains Chinese.

The difference between the ancient Chu language and the northern Chinese language may be mainly reflected in the vocabulary and phonetics. "Mencius Tengwen Gong I" records that Mencius also said when he ridiculed the Chu people Xu Xing, "Now there is also a person with a tongue in the south." However, since Xu Xing was able to preach his doctrine "from Chu Zhiteng" and communicate with the Chen Xiang brothers from "Zi Song Zhiteng", although the Chu language at that time was different from the language of the northern Central Plains, it was still a dialect of Chinese.

From the perspective of Chu in a broad sense, Xiaoxiang is within the scope of Chu State. Therefore, we can think that the "Chu language" of the Han Dynasty, especially the Chinese language of "Southern Chu", is the predecessor of the modern Hunan language. Tanzhou has been in the cultural and political center of the place in history, Qin set up Changsha County, the Western Han Dynasty placed Changsha State, Sui set up Tanzhou Prefecture County, Song Dynasty set up Jinghu South Road Road Governance, Qing set up the Right Bu Political Envoy Division, and Hunan Provincial Envoy Department was in Changsha...... Until today, due to the mentality of superiority formed by the central geographical advantages of Hunan in Tanzhou, it does not change as fast as the dialects around Xiaoxiang, and it is the closest language family to the ancient Hunan language.

Although linguists believe that the modern Hunan language still retains most of the continuity of the ancient Hunan language, they ignore the changes in the language caused by internal factors in this underground society for more than 2,000 years. The simple living environment and the state of life on the verge of danger at any time make the language of this civilization develop in the direction of simplicity and simplicity.

When Zhao and Xie took out the traditional Chinese letters prepared by the linguists in advance and handed them them, these underground Han people also encountered headaches, and even the full-time cultural people who were priests were equally confused after receiving the letters. An ancient Chinese letter was rushed up by language experts in the Tanzhou Wanjia International Survivor Guardian Center, and everyone present could not read it.

Since there are no brocades in the underground world, the bamboo slips and brocade books brought more than 2,000 years ago have long since decayed due to the humid environment, and there is almost no way to use language to pass on culture.

These underground Han people were deeply wary of the two of them. In their eyes, the two are not only strangely dressed, but also "different" in appearance.

In the closed underground environment for more than 2,000 years, the high frequency of marriage between the same population, the dominant genetic manifestations of human beings are very obvious, and these people almost all have the same characteristics. In addition, the long-term underground life, like all cavemen, has a lack of sunlight that hinders the production of pigment in the body, and they also show albinism. The different external physiological manifestations make it impossible for them to immediately accept that the two are the same species.

Zhao Xinghua and Xie Yunhao did not expect that the underground journey to find relatives would begin in a tense atmosphere.

Without the threat of those apemen, these underground Han people pointed their weapons at the two of them again, until Zhao Xinghua suddenly flew and jumped towards a rock, and after quickly carving it on it with a fanged dagger, all the underground humans surrounding suddenly burst into a surprise cheer!

On that rock, there is a Chinese script that has been passed down for more than 2,000 years.

"Han"

Where the sun and the moon shine and the rivers go, they are all Han soil!
