In 631, Master Xuanzang arrived in Zhongtianzhu Kingdom and was warmly received by King Jingri, after which he began friendly exchanges with the Tang Dynasty.
In 643, Emperor Taizong of Tang ordered Wang Xuance to send an envoy to Tianzhu. Wang Xuance, a native of Luoyang, year of birth and death unknown. He was an outstanding diplomat and military strategist of the Tang Dynasty, and successfully sent four envoys to Tianzhu.
In 647, Wang Xuance was appointed as the envoy and Jiang Shiren as the deputy envoy, and led 30 people to send another envoy to Tianzhu. After the mission arrived in India, it was just in time for the king of the Jiri to accidentally drown in a bath in the Ganges, and the state was in turmoil. The minister Alonashun usurped the throne and plundered the Tang Dynasty mission. Many of the mission's members were killed, and the survivors were taken prisoner, including Wang Xuance and Jiang Shiren.
Later, Wang Xuance and Jiang Shiren managed to escape from prison, and instead of fleeing directly back to Chang'an to file an emergency, they fled to the Tang Dynasty's vassal state of Nepal (Nepal) for help. At that time, both the princesses of Nibhara and the Tang Dynasty's Princess Wencheng were married to Songtsen Gampo of Tubo.
After Wang Xuance's lobbying, Nebra lent him 7,000 cavalry. Wang Xuance borrowed another 1,500 elite soldiers from Tubo Wang Songtseng Gambu. Another Zhang Qiuba country also sent more than a thousand soldiers. Located in the southwest of Tibet's Shigatse region, next to Nepal, the state of Zhangqiuba is a small state.
Wang Xuance led this joint army to attack the Zhongtianzhu Kingdom. The two armies took the battle, and after three days of continuous fighting, Wang Xuance broke through the Tianzhu army, he first used the fire bull array to defeat the 60,000 elephant army of Tianzhu in one fell swoop, and then he even counted several cities, beheading more than 3,000 people, and the Tianzhu army went to the water to drown more than 10,000 people.
Alona abandoned the city and was defeated, and Wang Xuance gathered the remnants, pursued them with victory, and defeated the reinforcements of the Eastern Tianzhu Kingdom. Later, Alonashun was finally captured, and tens of thousands of men and women of Zhongtianzhu Kingdom were captured, and thousands of prisoners were killed. The entire Indian region was terrified, and more than 580 cities rushed to show goodwill.
In 648, Wang Xuance escorted Alonashun and others to Chang'an, where he was deeply rewarded by Emperor Taizong of Tang and rewarded him with the post of Chaosan Dafu.
After Wang Xuance escaped from prison, he single-handedly turned a lotus flower on his tongue, said that he mobilized the three kingdoms to help the army, and defeated the huge Zhongtianzhu Kingdom without sending a soldier from the Tang Dynasty, achieving the ancient myth of "one man destroys one country" as later generations, and his glorious achievements are enough to blaze in history.
Later, Wang Xuance also sent two envoys to Tianzhu, ensuring the peace of the Sino-Indian border for hundreds of years. Due to the distance of thousands of miles and the difficulty of transportation, the one-way journey to Chang'an took more than half a year, and it was difficult to "rule with a long arm", and the Tang Dynasty did not include the India laid down by Wang Xuance into the territory, but only made it submit.
Wang Xuance also imported a lot of things from India, such as Buddhist scriptures and Buddha statues. The most precious of these is the Buddha's top bone relic that he invited back to offer. The introduction of the Buddha top bone relics, coupled with the early Buddha finger relics and the Buddha tooth relics, allowed Chang'an to gather the world's three major relics. These Buddhist holy relics made Chang'an the Buddha capital of the East.
Wang Xuance also offered a 200-year-old Tianzhu Fangshi to Emperor Taizong of Tang. Tianzhu Fangshi boasted that he was proficient in the art of alchemy, fooling that the elixir he refined could live forever. Emperor Taizong of Tang was very superstitious about him and took "elixirs" every day.
Tang Taizong was originally in good health and prosperous in spring and autumn, but after eating "elixirs" for a year, his health deteriorated sharply, and he died at the age of 51, presumably due to mercury poisoning.
After Emperor Gaozong of Tang succeeded to the throne, Li Zhi was held accountable, blaming Wang Xuance for offering the Tianzhu Fangshi, and although he was not imprisoned, he was no longer used and left him idle.
