Li Xuan said to himself. He took the Spiritual Pen and started to draw on the Spiritual Paper. Then, he started to write the word 'explosion' on it.
Around the 'explosion' word, Li Xuan drew a twisting spirit pattern. This was the most basic Spirit Pattern, and it had very low requirements. The requirements for the shape and drawing method were also very low.
The only requirement was that when drawing the Spirit Pattern, one had to inject Spiritual Power evenly. There could not be any uneven situation. If the Spiritual Power was too much or too little, there would be problems.
If the Spiritual Power was too little, it might not be able to trigger the Spirit Talisman, or the power of the Spirit Talisman would decrease. If the Spiritual Power was too much, it would cause the Spirit Talisman to burn and explode.
