Of course, Chu Chu wouldn't refuse the help of a cultivator that had reached the 'master level' in the field of saber techniques. Although he had cheated to increase his skills, Song Shuhang's comprehension of saber techniques had indeed reached the master level!
Thereupon, Song Shuhang began to teach Chu Chu about the foundations of saber techniques.
The methods he used were the same as that young man wearing green clothes he met in Venerable White's illusory reality—simple and crude.
At first, he explained to Chu Chu how to use all sorts of saber techniques. Then, he picked up his treasured saber Broken Tyrant and decided to let Chu Chu experience the charm of saber technique with her body.
The only problem was that Chu Chu didn't have a saber with her at this time. Therefore, she had no choice but to use her sword to execute saber techniques, increasing the difficulty of the training.
