Returning to Poland ca. 1630 or 1631 (sources vary), he joined the royal court and was named starosta of Nakło.[2][3] He was elected a deputy to the convocation sejm of 1632;[2][3] then again in 1635. In 1636 he was elected to the Crown Tribunal.[2] In 1634[3] or 1636[1] (sources vary) he joined the Jesuit Order, declared his intent to become a missionary in distant lands,[1] and began studies in theology at Kraków.[2][3]
After a journey during which he fell ill and almost died, in 1646 he arrived in Macao.[1] He studied Chinese language and customs in Jiangnan and Hangzhou.[1] Then he moved to Nanjing and adopted the Chinese name, Mu Ni-co (also spelled Mu Ni-ko, Mu Nike, Mu Nigo; some sources add a third part, Rude, as in "Mu Nigo, Rude").[3][4] He began his missionary activities in Nanking, but about 1647 a civil war forced him to move to Jianyang in the Chinese province of Fujian. In the years 1648–51 he worked as a missionary.[2][4]
He also taught astronomy and mathematics, introducing logarithms to China, and was much respected by Chinese scholars.[3][4][5] His fame as a scholar and teacher spread, and in 1653 he was invited by the Shunzhi Emperor to his court in Beijing.[2]
Smogulecki requested permission to leave the court to continue his missionary travels.[4] He went to Manchuria, then to Yunnan, where another civil war made him travel to Guangzhou. He visited the island of Hainan, then returned to the mainland.
On 17 September 1656 he died in Zhaoqing, Guangdong Province. (The city name is variously transcribed as Tszan-King, Zhaojing, Zhaoging Fou; sources vary).[2][3][4]
