"The enemy commander is old in age, he is cautious and careful. It will not be easy to fool him, but his cautious nature is also his downfall. If our opponent today was that animal He Rong Hui of our Black Iron Camp, even if the main ship blew up completely, he would still rob a boat to come fight me. It would not be easy to deal with then." Gu Yun murmured and kneaded his eyes subconsciously with his hand. His vision was blurred. Just now he was too tense to notice. At this time, he realized that it was time to drink medicine. He smiled at Yao Zhen, whose soul still had not returned. He ordered, "Sail back!"

Back in the Marshal tent, Gu Yun didn't dare to rest. He wanted to make up an emergency war report to send to the imperial court, he also had to deploy the war preparations to avoid such a situation of lacking here and there just now.

He had to ask someone to boil a bowl of medicine for him first. While waiting for its effect, he was whetting the ink and studying how to hold the Western army for some time in the future. Suddenly, a sharp stabbing pain at his nape and back from when he collided with the ship just now arose, creating a large area of bruising. Gu Yun’s hand trembled, the whetstone unexpectedly slipped out of his hand and fell down.

He gritted his teeth, reached for the table, and waited for the pain to pass.

But this time, the pain was unusually severe. Tormenting him for half an hour, until his back was soaked with cold sweat, it gradually became numb and faded.

At this time, Gu Yun found a very serious problem.

His hearing and eyesight that should have become clear again, still had not recovered.

Gu Yun's heart suddenly sank. A moment later, he realized something and looked down at the blurry medicine bowl in front of his eyes.

He did not panic, for he knew this day would come, but momentarily, he still found it difficult to fully accept. Much like how everyone knew they would die sooner or later, when closing their eyes, most people would not be so willing.

In front of the noisy Liangjiang camp, the coming enemy had retreated, but the warning of the attack had not been lifted. The sharp whistle still rang all around, but in Gu Yun's ears, the sound was like a distant line of sobs.

His world was fuzzy and quiet, the black ink and white paper on the table, in his eyes, were only two masses of blurry colors.
