  Recently, a novel direct counterfactual quantum communication protocol was
proposed using chained quantum Zeno effect. We found that this protocol is far
from being widely used in practical channels, due to the side effect of
'chained', which leads to a dramatic increase of the equivalent optical
distance between Alice and Bob. Therefore, not only the transmission time of a
single bit increases in multiple times, but also the protocol is more sensitive
to the noise. Here, we proposed an improved protocol, in which quantum
interference is employed to destroy the nested structure induced by 'chained'
effect. Moreover, we proved that a better counterfactuality is easier to be
achieved, and showed that our protocol outperforms the former in the presence
of noises.
